Shirt pallet with retractable arms

FIELD OF THE INVENTION
The present invention relates to pallets used to support garments during screen printing, and more particularly, relates to such pallets which allow for printing over an entire side of a shirt, including the arms.
BACKGROUND OF THE INVENTION
Conventional screen printing on garments such as T-shirts was traditionally limited to printing over only a small portion of the middle of the shirt. Accordingly, pallets were designed which supplied the requisite support to the center portion of the shirts during printing and maintained the center portion of the shirts in a stationary position as the shirts and pallets were advanced into successive registration with each of a number of printing stations whereby the composite of the colors printed at each of the stations resulted in production of a multi-colored image on the center portion of the shirt.
Recently, there has been a demand for T-shirts having printing over substantially the entire surface of the shirt, particularly including the sleeves. To accomplish this, belt presses are employed wherein the shirts are laid flat on a conveyor belt which transports the shirts to one or more printing units. Since there is nothing inside the shirts, as there is when utilizing conventional pallets, the shirts lay completely flat, so that prints can be made to extend across the entire side of a shirt front or back with little or no gap at the lateral edges of the shirt, which gaps are unavoidable when utilizing conventional pallets. Thus, the images printed on one side of the shirt can meet the images printed on the other side of the shirt to allow for a continual image extending across the front and back of the shirt. To assure that the print extends completely to the lateral edges of the shirt and particularly to allow print to cover the sleeves, prints are actually made larger than the shirt so that the print extends beyond the outer edges of the shirt. Thus, the print extends not only over the entire side of the shirt including the sleeves, but also extends beyond the edges of the shirt, with the portion of the print extending beyond the shirt edge being applied directly onto the belt upon which the shirt rests.
Belt presses have been found to suffer numerous shortcomings. A principle shortcoming is the high initial purchase cost of belt presses. Another shortcoming is that the belt must be cleaned following each printing before another shirt can be loaded onto the belt. This results not only in additional expense associated with the washing mechanism and/or personnel to carry out the washing, but also imposes a limitation as to the types of inks which can be applied since many types of inks, such as plastisol, are not easily removable from the belt. Additionally, since the print extends beyond the edges of the shirt, there is considerable waste of ink which is printed on the belt only to be later scrubbed off.
A still further shortcoming of belt presses is inaccurate alignment. Since the shirts are not secured upon a pallet, as is the practice with more conventional rotary screen presses, but, rather, merely lay upon the belt, detailed prints are not achievable. That is, even where adhesive spray is applied to the belt, the adhesive will only secure the back side of the shirt in a stationary position on the belt, while the front side of the shirt which is to be printed upon remains free to move around. Thus, even during printing of one color at a single station, design detail is limited due to the freedom of movement of the top side of the shirt, wherein the shirt moves slightly during printing resulting in a blurred image if too much detail is attempted. Furthermore, printing of multi-colored images requires very accurate registration from one print to the next which accuracy is not achievable with belt printers due to the aforementioned freedom of movement of the shirt resting on the belt. Thus, belt press prints are usually limited to at most only two or three colors, with limited design detail.
Also, flash curing of inks is limited due to the effect of the heat on the belt. While flash curing is attainable with some belts, this is generally only employed to print on dark material in which a base of white ink is applied and flash cured prior to printing another color directly on top of the white ink. Due to the aforementioned inaccurate registration between successive prints, such accurate multilayer printing techniques are not realizable with belt presses.
In light of the above discussed shortcomings associated with belt presses, it is desirable to provide a pallet for supporting a shirt which allows for printing over the entire surface of the shirt, particularly including the sleeves, which pallet maintains the shirt in a stationary position thereupon as the pallet is brought into successive registration with each of a plurality of printing units to provide the requisite registration accuracy necessary to make detailed multicolored prints.
Moreover, it is desirable to provide a pallet which allows for printing over the entire surface of a shirt which lends itself to employment on conventional rotary screen presses, particularly allowing for retrofit onto pre-existing rotary screen presses. This would preclude manufacturers wishing to print images over the entire shirt surface from having to purchase a completely new press to achieve this, as is currently required.
Such pallet should lend itself to commercial production, allowing for rapid loading and unloading of shirts therefrom for good productivity and decreased turnaround time. It is also desirable that the pallet lend itself to simple and economical manufacture.
SUMMARY OF THE INVENTION
In accordance with the present invention there is provided a pallet for supporting shirts for printing over a substantially complete side thereof, including the sleeves, with a single print on a rotary press, which complete printing coverage is not attainable with current pallets. The pallet of the present invention maintains the shirts in a stationary position as the pallet is moved between successive print stations, allowing for significantly greater detail of prints than attainable with belt presses.
A thin upper panel is mounted to a lower panel for movement between a raised position in which the upper panel is spaced from the lower panel, and a lowered position in which the upper panel abuts the lower panel. Shirts are placed over the thin upper panel while in its raised position, with the thin panel being received within the shirt body and being of a proportional lateral width with respect to the shirt to pull the shirt body taut. To provide support to the sleeves of the shirt, separate sleeve panels are provided which are mounted to the upper panel for sliding movement outward of the upper panel at the location at which the shirt sleeves are positioned.
The sleeve panels are in a retracted position, inward of the lateral sides of the upper panel, while the shirt is pulled over the upper panel. After a shirt has been pulled onto the upper panel, the sleeve panels are then pulled outward into the arm portion of the shirt. This pulls the shirt sleeves taut. Thereafter, an operator holds the shirt taut as the upper panel is moved to its lowered position abutting the bottom panel. The bottom side of the shirt is thus secured between the upper and lower panels to maintain the shirt in a stationary position during printing. While the upper panel is too thin to withstand the loads encountered during printing operations by itself, the provision of the bottom panel onto which the upper panel is lowered provides the requisite pallet support.
A particular feature of the present invention is that the sleeve panels and upper panel form a generally continuous planar surface upon which the shirt rests during printing. Also, the sleeve panels are restrained from being pulled inward by the tautness of the shirt with the design of the present invention.
The sleeve panels include a thicker outer portion which steps down to a thinner inner portion, and are supported so that they are spaced slightly from the underside of the upper panel when the upper panel is in its raised position. There is some play in the support of the sleeve panels, such that upon lowering of the upper panel into abutment with the lower panel the sleeve panels are urged against the upper panel. The sleeve panels are retracted during shirt loading whereby the entire sleeve panel lies beneath the upper panel, spaced slightly therefrom. The sleeve panels are designed so that, upon pulling out of the sleeve panels, the thicker outer portion of the sleeve panels are brought outward of the lateral sides of the upper panel, with the thinner inner portion of the sleeve panels remaining directly beneath the upper panel.
After a shirt has been loaded and the sleeve panels pulled outward to support the shirt sleeves, the upper panel is moved to its lowered position into abutment with the lower panel. This forces the sleeve panels against the upper panel, whereby the thicker outer portion of the sleeve panels is raised upward to form a generally continuous planar surface with the upper panel. The sleeve panels are thereby also prevented from moving inward under the influence of a taut shirt due to abutment of the inner edge of the thicker outer portion of the sleeve panels against the lateral edges of the upper panel.
Accordingly, the shirt is retained in a stationary, taut position on the pallet with the entire shirt supported on a generally continuous planar surface which allows for detailed printing over an entire side of a shirt, including the sleeves, to be carried out on a rotary press.
This design allows for rapid loading and unloading of shirts while still allowing for printing over the entire surface of the shirt. Accordingly, production rates approaching that of belt printers is attainable with the pallet of the present invention without the shortcomings associated with belt presses. Furthermore, since this design lends itself to retrofit with pre-existing rotary presses 14 having a rotatable turret 15 carrying a plurality of pallets, the cost for performing full shirt prints is minimal in comparison with the cost of purchasing a belt press for this purpose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment of a pallet embodying various features of the present invention is illustrated in FIGS. 1-12 and referred to generally at 20. With initial reference to FIG. 12, the pallet 20 comprises a thin upper or top panel 22 which is pivotally connected to a lower or bottom panel 24 through a hinge 25 to allow for pivotal movement of the upper panel 22 between a raised position in which the upper panel 22 is spaced from the lower panel (see FIG. 7), and a lowered position in which the upper panel 22 abuts the lower panel 24 (see FIG. 9). The thinness of the upper panel 22 minimizes the amount of shirt material at its lateral sides so that a print can be made over the entire front surface of a shirt and another over the entire back surface of a shirt which prints will nearly meet. This is in contrast with conventional pallets in which the pallet is unibody, having a thickness which causes large gaps between prints done on the frontside of the shirt and prints done on the backside of the shirt. Simply making the conventional unibody pallets thinner is not a feasible alternative since the thin pallets do not provide enough strength to withstand the loads encountered during printing. Thus, the provision of separate upper and lower panels is required.
The upper panel 22 has two sleeve panels 26 mounted thereto for pivotal movement between a retracted position as illustrated in FIG. 10 and an extended position as illustrated in FIG. 11. A shirt 28 to be printed is pulled taut over the upper panel 22 with the sleeve panels 26 in their retracted position, as illustrated in FIG. 7. Then the sleeve panels 26 are pulled outward to their extended position into the sleeve of the shirt 28 to pull the shirt sleeve taut, with the upper panel 22 maintained in its raised position, as illustrated in FIG. 8. Thereafter, the upper panel 22 is lowered and rests on the lower panel securing the shirt 28 between the upper and lower panels.
To allow for movement of the sleeve panels 26 between their retracted and extended positions, in the preferred embodiment the sleeve panels 26 include a pivot aperture 30 and the upper panel 22 includes a mounting aperture 32 through which the sleeve panel 26 is mounted for pivotal movement with respect to the upper panel 22 about the pivot apertures.
The extent of pivotal movement of the sleeve panels 26 with respect to the upper panel 22 is defined by arcuate slots 34 formed in the sleeve panels 26. Pins 36 extend from the upper panel 22 down through the arcuate slots 34, and are retained within the arcuate slots 34 by washers 38. Thus, as seen in FIG. 10, as the sleeve panels 26 pivot about the pivot aperture 30, the extent of retraction of the sleeve panels 26 is defined by abutment of the pin 36 against the outer end 40 of the arcuate slot 34, and the extent of extension of the sleeve panels 26 is defined by abutment of the pin 36 against the inner end 42 of the arcuate slot 34. This precludes the need for precise operator positioning of the sleeve panels 26 and also provides support of the sleeve panels. The washers are preferably formed of plastic material to allow low friction sliding.
For reasons to be discussed below, it is desirable that the washers 38 be spaced from the upper panel so that there is space or play between the upper side 44 of the thickened outer section 52 of the sleeve panels 26 and the underside 46 of the top panel 22. Further support of the sleeve panels 36 is provided by receipt of the upper end 48 of the sleeve panels within brackets 50 mounted to the underside 46 of the upper panel 22. The brackets 50 allow for some movement of the sleeve panels 26 therein between the position of FIG. 3 in which the sleeve panel 26 is spaced from the upper panel 22, and the position of FIG. 4 in which the sleeve panel 26 abuts the upper panel 22. This is an important aspect of the present invention which is discussed in detail below.
In order to provide for a generally continuous planar surface upon which to carry out printing operations, and to prevent the sleeve panels 26 from being pulled toward their retracted position under the influence of the tautness of a shirt stretched thereacross, the sleeve panels 26 include thicker outer sections 52. In the preferred embodiment of the invention, the thicker outer sections 52 of the sleeve panels 26 are formed by simply attaching a small plate 26a to the top surface 54 of the sleeve panels 26. While this is preferred for economy of manufacture, clearly other suitable means of forming a thickened or widened outer section 52 may be employed without departing from the inventive concepts of the present invention.
The thickened outer sections 52 of the sleeve panels 26 extend only to the lateral sides 56 of the upper panel 22 when the sleeve panels 26 are moved to their extended positions. That is, the thickened outer sections 52 step down along a line or path defined by the position of the lateral side 56 of the upper panel 22 with respect to the sleeve panel 26 when the sleeve panel is moved to its extended position, as best seen in FIG. 2.
The aforementioned provision of space between the sleeve panel 26 and the underside 46 of the upper panel 22 accomplishes at least two separate objectives.
First, it allows the thickened outer section 52 of the sleeve panels 26 to slide beneath the upper panel 22 without contacting the underside 46 thereof. This is particularly important in applications in which adhesive spray is applied to the upper surface 44 of the outer section of the sleeve panels 22 to assist in securing the shirt 28 in a stationary position. Without the sufficient clearance allowed by the bracket 50 support, the sleeve panels 22 would get hung up when moving between extended and retracted positions.
Second, with reference to FIGS. 3 and 4, after the sleeve panels 26 have been moved to their extended position with the upper panel raised, the sleeve panels 26 remain spaced slightly from the underside 46 of the upper panel 22. With the sleeve panels 26 fully extended and the upper panel 22 in its raised position, as shown in FIG. 3, the thickened outer sections 52 of the sleeve panels 26 are positioned such that the inner edge or step down 58 thereof extend just outward of the lateral sides 56 of the upper panel 22, being also spaced slightly below the upper panel 22. Thus, upon lowering of the upper panel 22 onto the lower panel 24, the sleeve panels 26 are forced against the underside 46 of the upper panel 22, thereby taking up the space therebetween. This raises the thickened outer section 52 of the sleeve panels 26 upward to bring the upper surface 44 of the thickened outer section 52 of the sleeve panels 26 into a generally level relationship with the upper surface 60 of the upper panel 22. Accordingly, after the shirt 28 has been secured on the upper panel 22 and the panel is thereafter lowered into abutment with the lower panel 24, the entire shirt, particularly including the sleeves, is supported on a generally planar surface for printing.
It is desirable to minimize the gap between the inner edge 58 of the sleeve panels 26 and the lateral sides 56 of the upper panel 22. Otherwise the print will be distorted thereat. The design of the present invention accomplishes this objective inherently. When the sleeve panels 26 are extended, the shirt 28 is pulled taut. The tautness of the shirt 28 exerts an inward force on the sleeve panels 26, tending the panels 26 toward their retracted position.
While this would result in inward movement of the sleeve panels 26 were the upper panel 22 maintained in its raised position, due to the aforementioned allowance of space for movement of the thickened outer section 52 beneath the upper panel 22 (as best illustrated in FIG. 3), the sleeve panels 26 are prevented from moving inward when the upper panel 22 is in its lowered position due to abutment of the inner edge 58 of the sleeve panels 26 against the lateral side 56 of the upper panel 22.
Thereafter, following printing operations, the upper panel 22 is raised again and the shirt pulled off the pallet 20, so that the sleeve panel 26 resumes the position illustrated in FIG. 3.
The potential for pinching a portion of the shirt between the sleeve panels 26 and the upper panel 22 upon retraction of the upper panel is also minimized by the construction of the preferred embodiment. Since the upper surface 44 of the sleeve panels 26 drops down to a plane below the upper surface 60 of the upper panel 22 upon raising of the upper panel 22, the shirt 28 is thereby peeled from the adhesive which is normally employed on the upper surface 44 of the sleeve panels upon raising of the upper panel 22. Thus, the shirt is peeled from the sleeve panels 26 prior to retraction of the sleeve panels 26, so that the shirt does not stick to the sleeve panels when they are retracted, whereby otherwise the portion of the shirt adhering to the sleeve panel would be pulled and pinched between the panels.
To move the upper panel 22 between its raised position in which it is spaced from the lower panel 24, and its lowered position in which the upper panel 22 abuts and rests atop the lower panel 24, wheels 62 are employed. With reference now to FIG. 6, wheel openings 64 are provided in the lower panel 24 through which the wheels 62 are raised to lift the upper panel 22 to its raised position, as shown in FIG. 2. The wheels 62 are lowered to a position beneath the lower panel 24 to bring the upper panel 22 to its lowered position abutting the lower panel 24.
Any of the several commercially available over-center devices 66 can be employed to lock the wheels 62 in a raised position by movement of a handle 68 in a first direction, and thereafter lower the wheels 62 by movement of the handle 68 in an opposite second direction. A DE-STATO-202 clamp has been found to be effective. As best seen in FIG. 6, a pair of wheel mounting blocks 70 are affixed to the underside 72 of the lower panel 24. A wheel supporting axle 74 spans the wheel mounting blocks 70 and is mounted for rotation therein. An actuating bracket 76 and a pair of wheel supporting brackets 78 are fixedly secured to a common wheel supporting axle 74 whereby raising the actuating bracket 76 effects the simultaneous raising of the pair of wheel supporting brackets 78 and, hence, raising of the pair of wheels 62 through the wheel openings 64 as illustrated in FIG. 6.
Hence, an operator moves the handle 68 of the over-center device to raise the wheels 62 upward through the wheel openings 64 provided in the lower panel 24, whereby the wheels 62 exert an upward force against the underside 46 of the upper panel 22 to lift the upper panel 22 to its raised position, as illustrated in FIGS. 2 and 6.
With the upper panel 22 in its raised position supported upon the wheels 62 and the sleeve panels retracted, an operator pulls a shirt 28 taut over the upper panel 22 so that the upper panel 22 and sleeve panels 26 are received within the shirt 28. Then, the operator grips the lip 27 of the sleeve panels 26 and pulls them outward to their extended position into the sleeves of the shirt to make the shirt sleeves taut. Since it is desirable to hold the shirt taut as the upper panel 22 is lowered onto the lower panel 24, a hydraulic or pneumatic cylinder 82 is mounted to the frame 84 of a press. The cylinder 82 is actuated by a foot switch 86 connected thereto which reciprocates a knock-out arm 88 to knock the handle 68 of the over-center device to lower the wheels 62 and hence lower the upper panel 22. This allows the operator to maintain a grip on the sleeve panels 26 with both hands to keep the shirt taut while the upper panel 22 is lowered. Of course, pneumatic or hydraulic cylinders can be employed to both raise and lower the upper panel 22, however, since it takes less time to unload a shirt from the pallet 20 than to load a shirt onto the pallet 20, the expense associated with such fully foot operated raising and lowering is not justified.
The lower panel 24 includes arcuate recesses 90 where the lips 27 of the sleeve panels 26 meet the lower panel 24 in their extended positions. This allows the operator to maintain a grip on the sleeve panels 26 during lowering of the upper panel 22, without concern for fingers getting caught between the upper panel 22 and lower panel 24.
To prevent the wheels 62 from impeding the movement of the sleeve panels 26 between retracted and extended positions, the sleeve panels are provided with cutout sections 80. That is, with the sleeve panels in their retracted position, were it not for the provision of the cutouts 80, the wheels 62 would be forced against the sleeve panels 26 when raised, rather than being forced directly against the upper panel 22. The abutment of the wheels 62 against the sleeve panels 26 would provide undesirable resistance to outward movement of the sleeve panels 26 were it not for the provision of the cutouts 80.
Other means for raising and lowering the upper panel 22 with respect to the lower panel 24 can be employed without departing from the inventive concepts of the present invention. For instance, springs can be employed at the base 82 of the upper panel 22. However, such arrangements have been found to result in bowing of the relatively thin upper panel 22 under its own weight when the upper panel elevating means is positioned at the base rather than being spaced from the base, as provided for with the wheel arrangement of the present invention. The wheel arrangement of the present invention is desirable in that the rolling action of the wheels 62 allows the shirt 28 to pass between the wheels 62 and the underside 46 of the upper panel 22 with little resistance.
In the preferred embodiment of the invention, the panels are all interconnected at the hinge 25. As seen in FIG. 12, the hinge includes an upper flange 29 and a lower flange 31. The upper panel 22 and sleeve panels 26 are connected to the upper flange 29 of the hinge 25, and the lower flange 31 of the hinge 25 is connected to the upper end 94 of the clamps 92. The clamps 92 are then in turn clamped to mounting brackets 96 which are mounted to the underside 72 of the lower panel 24.
Thus, the lower panel 24 and the mounting blocks 96 mounted to the underside 74 thereof are permanent components, and remain mounted to the press, while the upper panel 22 which is connected to the clamps 92 through hinges 25 is removable from the lower panel 24 by simply loosening the clamping screws 98 of the clamp 92. This arrangement allows for accommodation of differently sized shirts since the upper panel 22 is mounted for simple and rapid interchangability.
Hence, any number of differently sized upper panels 22 can be maintained to accommodate differently sized shirts 28, with each upper panel 22 being connected to respective clamps 92 through hinges 25, whereby upper panels 22 are readily interchangeable by simply clamping and unclamping to the mounting blocks 96. Once clamped, the upper panel 22 is then hingedly connected to the lower panel 24 for pivotal movement with respect thereto.
To assure that the upper panel 22 rests flat against the lower panel 24, the lower panel is provided with a number of cutouts to accommodate hardware extending downward from the underside 46 of the upper panel 22. Specifically, in the illustrated embodiment, bracket cutouts 100 are provided in the bottom panel 24 to accommodate the brackets 50 and pin cutouts 102 are provided in the lower panel 24 to accommodate the pins 36 and their associated washers 38. Depending upon the exact pallet construction utilized, should it differ from the preferred embodiment, other cutouts may be required so that the upper panel 22 lays flat atop the lower panel 24 to assure securing of the shirt 28 therebetween.
To further assure that the upper panel 22 lays flat against the lower panel 24, a neck cutout 106 is provided in the bottom panel 24 to accommodate the thickened neck portion of T-shirts therein, which thickness in relation to the remainder of the T-shirt would otherwise preclude the upper panel 22 from laying flat upon the lower panel 24.
Thus, in operation of the pallet 20 of the preferred embodiment discussed above, an operator first manually raises the upper panel 22 by movement of the handle 68 to unload a previously printed shirt 28 as it resides at an unloading station 10. Thereafter, the pallet 20 moves to an adjacent loading station 11 while still remaining in its raised position. Thereat, an operator pulls a new shirt 28 to be printed upon over the upper panel 22 by sliding the lower end of the shirt between the wheels 62 and the upper panel 22 and the upper end of the shirt over the upper surface 60 of the upper panel 22. Then the operator extends the sleeve panels 26 by pulling on the lip 27 thereof and pivoting the sleeve panels 26 into the sleeves of the shirt. While holding the sleeve panels 26 outward, the operator steps on the foot switch 86 to actuate the hydraulic cylinder 82 and knock out the handle 86 to lower the wheels 62 and hence lower the upper panel 22. This secures the underside of the shirt 28 between the upper panel and the lower panel 24 to maintain the shirt in a stationary position as it then advances through a plurality of printing stations 12 to receive the respective printing operations. When the shirt moves around to the unloading station following the printing operations, an operator manually raises the upper panel 22 by movement of the handle 86 and slide the printed shirt off the pallet 20. Thereafter, the raised pallet 20 advances to the loading station whereat the above procedure is repeated.
An alternative embodiment of a pallet embodying various features of the present invention is illustrated in FIG. 13 and referred to generally at 110. This embodiment is similar to the preferred embodiment in that the upper panel 122 is pivotally connected to the lower panel 124 and includes generally all of the other features of the pallet 20 of the preferred embodiment such as the wheel lifting mechanism and the like. This alternative embodiment, however, differs from the preferred embodiment in the construction of the sleeve panels. The sleeve panels 126 of the embodiment of FIG. 13 slide linearly between retracted and extended positions, rather than pivoting.
Each sleeve panel 126 includes two brackets 150 which the support the sleeve panel 126 for drawer-like sliding. An operator grips the lips 127 of the sleeve panels and pulls then outward into the sleeves of the shirt. As with the preferred embodiment, and for the reasons delineated with respect to the preferred embodiment, the outer section 126a of the sleeve panels 126 is made thicker than the inner section 126 of the sleeve panels. Thus, the brackets 150 should be designed to provide space for movement of the sleeve panels 126 therein. Hence, the thickened outer section 126a of the sleeve panels moves between a suspended position spaced from the upper panel 122 when the upper panel 122 is raised, to a position flush against the upper panel 122 when the upper panel is lowered, with the upper surface 144 of the thickened outer section 126a being moved to a position planar with the upper surface 160 of the upper panel 122 when the upper panel 122 is lowered.
The sleeve panels include cutouts 180 to accommodate the wheels 162 similar to the cutouts 80 provided in the sleeve panels 26 of the preferred embodiment.
This embodiment is not preferred in that it results in sharp corners 200 at the support of the armpits of the shirt, in contrast with the smooth radius 118 provided at the armpits in the preferred embodiment. This radius 118 pulls the shirt taut at the armpits to allow printing thereat. Also, the linear drawer-like sliding has been found to cause significantly more hang-ups than the pivotal arrangement of the sleeve panels provided in the preferred embodiment of the invention.
While the invention has been described with reference to preferred embodiments, it will be understood to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
