Description




FIELD OF INVENTION




This invention relates to butter dishes and more particularly to butter dishes that cut slices of butter.




BACKGROUND




People have used butter dishes for storing butter for a very long time. Obtaining a portion of butter is not necessarily a neat task. Butter may be difficult to slice whether the butter is warm or cold. When the butter is warm, uniform slices cannot easily be produced, producing more of a glob than a slice. When the butter is cold, it is difficult to cut the butter and even more difficult to produce flat, uniform slices. Other problems also exist.




Typically, a person will use a knife to cut a slice of butter. The person will then spread the butter onto a slice of bread or toast. This person may then apply peanut butter or jelly to the slice of bread or toast. This person may then wish to cut another slice of butter for a second slice of bread or toast. The knife will likely contain breadcrumbs, peanut butter, jelly, or other particles. When the person cuts the second slice of butter, the breadcrumbs, peanut butter, jelly, or other particles are transferred to the butter. Many people find the transfer of these particles from one person's food to another's food distasteful.




Another problem with customary butter dishes is that these dishes do not protect the butter from contact with undesirable insects. For example, when the butter dish is left on the counter top or placed on the table for use, the butter is usually unprotected. Flies and insects easily come in contact with the butter. The butter dish will not likely have a barrier by which to prevent these insects from landing on the butter and leaving tracks.




Another problem with typical butter dishes is that they are difficult to wash. Many butter dishes may not be placed into dishwashers because of the material of which they are made. Washing butter dishes by hand may be an adventure. Butter is oil-based which creates the difficulty in washing butter dishes. One must use extremely hot water to clean butter dishes. Often water this hot is intolerable for the person washing butter dishes. Moreover, the person's hands become coated in the oil found in butter.

SUMMARY




The present invention includes a receptacle mechanism for storage of a stick of butter or margarine (hereinafter butter). Inside the top portion of the receptacle mechanism is a push mechanism for pushing the butter down into the receptacle mechanism. A cutting mechanism for cutting slices of butter is attached to the lower portion of a frame mechanism. The frame mechanism also contains the receptacle mechanism.




The present invention prevents contamination of the butter within the receptacle mechanism. A person is able to obtain several slices of butter without using his/her knife. This prevents the person from needing to cut butter slices with his/her knife that he/she used with other food, which in turn prevents contamination of the butter with bread crumbs, peanut butter, jelly or other food particles and from allowing insects to attack the butter.




The present invention provides a method for easily obtaining a slice of butter with the use of only one hand. A person may grip the present invention with one hand by placing the frame adjacent to his/her palm and the receptacle mechanism adjacent to his/her fingers. The person then moves his/her fingers toward his/her palm, and thus, producing a slice of butter using only one hand.




In detailed operation, the person places a stick of butter into the receptacle mechanism. The push mechanism is next placed into the receptacle mechanism atop the butter. Pressured is applied to the receptacle mechanism by pulling the receptacle mechanism towards the back of the frame mechanism. This causes the push mechanism to move the butter into position for cutting. The pressure on the receptacle also causes a straight gear firmly secured to the receptacle to turn a round gear, which in turn moves a straight gear in a direction opposite the receptacle. The second straight gear is secured to a blade which slices through the butter extending below the receptacle. Release of the receptacle, allows the push mechanism to readjust relative to the receptacle; ready for the next slice.




DETAILED DESCRIPTION




The present inventive device


10


, shown in

FIGS. 1 through 7

, includes a receptacle mechanism


12


for containing butter or margarine, a push mechanism


14


for pushing the butter or margarine down into the receptacle mechanism


12


, a cutting mechanism


16


for cutting slices of the butter or margarine, and a frame mechanism


18


for encapsulating mechanisms


12


,


14


, and


16


. These mechanisms


12


,


14


,


16


, and


18


will be described in more detail below.




As seen in

FIG. 4

, the receptacle mechanism


12


may include an adjustment mechanism


20


, a pivot mechanism


22


, a gear sheet


24


, a view mechanism


26


, a pin box


28


, a plurality of strait gears


30


, and a cutting surface


32


. As seen in

FIG. 5

, the receptacle mechanism


12


also includes a gear sheet control mechanism


33


, a gear sheet return spring


35


, and an anchoring mechanism


37


. These will be described in more detail below.




The receptacle mechanism


12


may be of a variety of sizes, shapes, and materials. The preferred size is large enough to contain an entire typical stick of butter or margarine (hereinafter butter) as well as the push mechanism


14


. The receptacle mechanism


12


will preferably be a hollow rectangle. The receptacle mechanism


12


includes an upper rectangular opening (not shown) and a lower rectangular opening (not shown). The receptacle mechanism


12


preferably will be constructed of lightweight glass or plastic. Most preferably, the receptacle mechanism


12


will be non-breakable, clear plastic.




The adjustment mechanism


20


adjusts the thickness of the slice of butter. The adjustment mechanism


20


may be a rotatable oblong-shaped disc held with a screw or any other suitable mechanism for adjusting the thickness of the slice. The adjustment mechanism


20


works in conjunction with the gear sheet


24


and the gear sheet control mechanism


33


. The rotation of the adjustment mechanism


20


controls the distance the control mechanism


33


moves, e.g., the distance between the control mechanism


20


and the anchor mechanism


37


, thereby controlling the distance traveled by the push block


14


. The distance the push block


14


moves controls the thickness of the slice of butter.




The pivot mechanism


22


may be a plurality of pivot holes and pivot pins that enable the receptacle mechanism


12


to pivot within the frame


18


to an angle for improved cutting of a slice of butter or margarine. The pivot mechanism


22


works in conjunction with the frame mechanism


18


. The plurality of pivot holes works in conjunction with the pivot pins and the frame mechanism


18


to allow the receptacle mechanism


12


to pivot within the frame mechanism


18


.




The gear sheet


24


is located at the rearward wall within the receptacle mechanism


12


. A gear sheet channel


24




a


is created prior to the gear sheet


24


being positioned within the receptacle mechanism


12


. A pair of first blocks


24




b


is attached to the rearward inside corners of the receptacle mechanism


12


. A pair of second blocks


24




c


is then attached, perhaps homogeneously, to the pair first blocks


24




b.


The pair of second blocks


24




c


are slightly wider than the pair of first blocks


24




b;


this creates a small channel beneath the second blocks


24




c


and above the back of the receptacle mechanism


12


through which the teeth of the gear sheet


24


are exposed to the push mechanism


14


. The teeth of the gear sheet


24


are recessed beneath the second block


24




c,


which prevents the butter from coming into contact with the teeth of gear sheet


24


.




As described below, the gear sheet


24


, being drawn by the pin box


28


, moves downward during the beginning of the cutting stroke. The gear sheet


24


returns to the up position during the cutting process. As stated above, the adjustment mechanism


20


may be set to limit the control mechanism


33


from returning to the top position and thereby reduce the amount of movement of the gear sheet


24


which, in the end, results in thinner slices.




The view mechanism


26


may be a plurality of openings defined within the receptacle mechanism


12


. The view mechanism


26


allows the user of the present invention


10


to determine if the receptacle mechanism


12


needs to be refilled with butter or margarine. The present invention


10


may not include the view mechanism


26


particularly if the receptacle mechanism


12


is constructed of a transparent material.




The gear sheet control mechanism


33


may be any mechanism that will control the movement of the gear sheet


24


. The gear sheet control mechanism


33


may be a control block. The control block


33


is attached to the backside of the gear sheet


24


through the upper rectangular opening on the receptacle mechanism


12


. The control block


33


moves upward and downward with the gear sheet


24


. The adjustment mechanism


20


controls how far the control block


33


will move upward and thus controls the thickness of the slices of butter.




The anchoring mechanism


37


may be any mechanism that provides the gear sheet spring


35


with an anchor. The anchoring mechanism


37


may be an anchor block. The anchor block


37


is attached to the outside of the receptacle mechanism


12


beneath the upper rectangular opening. The anchor block


37


does not move with the gear sheet


24


. The anchor block


37


is stationary.




The gear sheet spring


35


is attached at one end to the control block


33


and attached to the anchor block


37


at the opposing end. The gear sheet spring


35


is forced down onto the anchor block


37


by the control block


33


as the gear sheet


24


moves downward. The gear sheet spring


35


re-extends at the end of the cutting stroke forcing the control block


33


to move upwards. The gear sheet


24


is forced upwards as the control block


33


moves upward, which causes the gear sheet


24


to return to its original starting position.




The pin box


28


may include a spring


34


and a plurality of control pins


36


. The pin box


28


is attached through the lower rectangular opening of the receptacle mechanism


12


to the back of the gear sheet


24


, forming the push block advancing mechanism


31


. When the receptacle mechanism


12


is moved back toward the frame mechanism


18


, the control pins


36


move downward (


1


) along the angled edge


39




a


of the pin box rotator


39


as shown in FIG.


7


. This movement causes the gear sheet


24


to move downward. The control pins


36


then move up the ramp


39




b


of the pin box rotator


39


(


2


), pushing the pins


36


into the pin box


28


. Once atop the ramp


39




b,


the gear sheet spring


35


forces the control block


33


to move upwards in the direction of the adjustment mechanism


20


, drawing the gear sheet


24


and pin box


28


upward. The compressed control pins


36


slide along the major surface


39




c


of the pin box rotator


39


as indicated at (


3


). The return stroke (


4


), caused by a main spring


64


(discussed below), pushes the frame


18


, secured to the pin box


28


back into their original positions, where the control pins


36


extend and are brought to rest against the angled edge


39




a.


The rotation of the pin box


28


completed, the device


10


is ready for the operation.




The plurality of strait gears


30


, shown in

FIGS. 4 and 5

, may be any typical strait gears. The strait gears


30


may be permanently attached to or integral with outside surface of the sides of the receptacle mechanism


12


. The strait gears


30


may be located near the lower portion of the receptacle mechanism


12


. The strait gears


30


interact with a pair of round gears


66


.




The receptacle mechanism


12


may have a cutting surface


32


. The cutting surface


32


is shown in

FIGS. 1

,


4


and


5


. The cutting surface


32


is the lower front edge of the receptacle mechanism


12


. The cutting surface


32


may be slightly longer than the remaining three lower edges of the receptacle mechanism


12


. The butter is cut against the cutting surface


32


.




As shown in

FIG. 2

, the push mechanism


14


may include a retrieval chain


38


, a storage area


40


, a guide bar


42


, a spring


44


, a plurality of pins


46


, a joggle plate


48


, a latch


50


and a latch pivot rod


51


. The retrieval chain


38


, the storage area


40


, the guide bar


42


, the spring


44


, the plurality of pins


46


, the joggle plate


48


, the latch


50


and the latch pivot rod


51


will be described in more detail below.




The push mechanism


14


is placed into the top of the receptacle mechanism


12


and then connected to the gear sheet


24


as explained below. The push mechanism


14


should be slightly smaller than the receptacle mechanism


12


so that the push mechanism


14


may be inserted into the receptacle mechanism


12


. The push mechanism


14


may be approximately 1 ⅔ inches by 1 ¼ inch by 1 ¼ inch.




The retrieval chain


38


is stored inside of the storage area


40


. The storage area


40


is located within the push mechanism


14


. The retrieval chain


38


is a thin chain attached to the latch


50


, which has a stop


53


disposed thereon to contain the chain within the areas as shown and described. When the butter needs to be refilled, a person tips the present invention


10


upside down and the retrieval chain


38


falls from the storage area


40


. The person pulls the retrieval chain


38


, which retracts the latch


50


. The person is then able to remove the push mechanism


14


and refill the butter.




The guide bar


42


is inserted into and attached to the push mechanism


14


. The retrieval chain


38


is placed beneath the guide bar


42


to change the angle/direction of pull to enable the retrieval chain


38


to pull back the latch


50


.




The spring


44


is attached to the inside of the push mechanism


14


. The spring


44


allows the latch


50


to generally remain in an extended position so that the latch


50


may lock into the teeth of the gear sheet


24


, during the downward stroke. The spring


44


allows the latch


50


to retract when the gear sheet


24


is sliding upward into its starting position. This allows the push mechanism


14


to only move downward and not move upward during the cutting process.




One end of the plurality of pins


46


attaches to the lower portion of the push mechanism


14


. The opposing end of plurality of pins


46


attaches to the joggle plate


48


. Butter tends to be sticky and, therefore, may stick to the joggle plate


48


. The plurality of pins


46


allows the joggle plate


48


to move downward, if attached to the butter, without moving the push mechanism


14


downward at the same time. This prevents extra thick slices of butter from being cut.




The latch


50


is attached to the latch pivot rod


51


. The latch


50


is releasably locked into the teeth of the gear sheet


24


. This causes the push mechanism


14


to move downward when the gear sheet


24


is moving downward. The latch pivot rod


51


allows the latch


50


to pivot during the movement of the gear sheet


24


, which allows the push mechanism


14


to move downward with the gear sheet


24


and, yet, not upward with the gear sheet


24


.




The cutting mechanism


16


, shown in

FIG. 3

, may include a blade


52


, a pair of blade-guide mechanisms


54


, a knock-off mechanism


56


, and a pair of blade gears


58


. The blade


52


, the blade-guide mechanisms


54


, the knock-off mechanism


56


, and the blade gears


58


will be described in more detail below.




The blade


52


may be any typical blade such as a razor blade or other similar type of blade. The blade


52


should be approximately the same width, or slightly wider than, the width of a stick of butter to ensure a complete cut through the butter. The blade


52


may be approximately ½ inch in width and the length of the blade


52


is approximately 2 and ½ inches. The blade


52


is attached to the pair of blade-guide mechanisms at each end.




The pair of blade-guide mechanisms


54


may be any mechanism that will guide the blade


52


forward and backward during the cutting process. The blade-guide mechanisms


54


may be oval-shaped or rectangular-shaped rings or slats. The pair of blade-guide mechanisms


54


may be approximately one and ¾ inches in length. One blade-guide


54


may be inserted onto the blade


52


at each end adjacent to the cutting edge.




The knock-off mechanism


56


may be any mechanism that separates the butter from the blade


52


. The knock-off mechanism


56


may be a long narrow strip that is attached at each end to the top of the pair of blade-guide mechanisms


54


. The knock-off mechanism


56


may be wedge-shaped. As the blade


52


slides forward through the butter, the knock-off mechanism


56


slides between the butter and the blade


52


.




The blade gears


58


may be any straight lined gear mechanism that meshes with the round gears


66


. The blade gears


58


may be approximately 1 and ¾ inch in the length. The blade gears


58


may be attached to the pair of blade-guide mechanisms


54


along their lengths.




The frame mechanism


18


is shown in

FIGS. 1 and 6

. The frame mechanism


18


may include a cover


60


, a frame


62


, a main spring


64


, a pair of round gears


66


, a track


68


, and a butter stop

may be approximately three inches by approximately two inches by approximately ⅛ inch in dimension. The cover


60


may be placed over a top portion


62




a


of the frame mechanism


18


. The cover


60


may be removed to insert or remove a stick of butter. The cover


60


may also be removed to insert or remove the receptacle mechanism


12


from the frame mechanism


18


.




The frame


62


may be slightly taller than eight inches. The frame


62


may include the top portion


62




a,


a base portion


62




b,


and an opening


62




c.


The top portion


62




a


may be approximately one and ⅔ inch in height. The base portion


62




b


may be approximately two and ⅓ inch in height. The frame


62


is approximately three inches in depth and two inches in width.




The frame


62


may be enclosed at the top portion


62




a


using the cover


60


. The base portion


62




b


may be separate from, though attached to, the frame


62


. The base portion


62




b


may include a butter retrieval opening


62




d


so as to allow the user of the present invention


10


to obtain the recently cut slice of butter, which falls from the butter retrieval opening


62




d


by the force of gravity. The opening


62




c


is defined in between the top portion


62




a


and the base portion


62




b.


The opening


62




c


allows the user to squeeze the receptacle mechanism


12


into a vertical position for cutting a butter slice.




The main spring


64


returns the receptacle mechanism


12


to its original starting position after cutting a slice of butter as stated above. The main spring


64


is a conical spring. The main spring


64


is attached at one end to the outside of the receptacle mechanism


12


and to the inside of the frame mechanism


18


at the opposing end. When force is applied to the receptacle mechanism


12


to move it back towards the frame mechanism


18


, the main spring


64


is forced against the frame mechanism


18


. The main spring


64


becomes flattened by this action. When the force on the receptacle mechanism


12


is released, the main spring


64


expands to its original shape and thus partially rotates the receptacle mechanism


12


about the pivot mechanism


22


and back to its original position.




The round gears


66


may be attached to the opposing inside walls of the base portion


62




b


as shown in

FIGS. 1 and 6

. The round gears


66


should be attached to the base portion


62




b


in such a manner as to allow the round gears


66


to turn when activated by the strait gears


30


. The round gears


66


are pinned to the inside of the base portion


62




b


of the frame


62


. The round gears


66


have an opening defined in the center. A pin, with a cap, is inserted through the round gears


66


. The pin is attached to an opening in the base portion


62




b.






The track


68


is located in the base portion


62




b


beneath the round gears


66


. The cutting mechanism


16


is inserted into the track


68


. When the receptacle mechanism


12


is pulled towards the back of the frame


62


, the cutting mechanism


16


will be moved forward to cut the butter.




The butter stop


70


prevents the butter from sliding out of the present invention


10


. The butter stop


70


may be any mechanism that prevents the butter from sliding out of the present invention


10


. The butter stop


70


is shown in

FIGS. 1 and 6

.




The present invention


10


is easy to use. The cutting mechanism


16


is inserted into the track


68


of the frame mechanism


18


. The receptacle mechanism


12


is inserted into the frame mechanism


18


if it is not currently within the frame mechanism


18


. Typically, the receptacle mechanism


12


will stay within the frame mechanism


18


. A stick of butter or margarine is inserted into the receptacle mechanism


12


. The push mechanism


14


is inserted into the top of the receptacle mechanism


12


lining up the teeth of the gear sheet


24


with latch


50


. The cover


60


is placed onto the top portion


62




a.






The user holds the present invention


10


with the opening


62




c


adjacent to the user's fingers and the back of the frame


62


adjacent to the user's palm. The user then pulls the receptacle mechanism


12


towards the back of the frame


62


. A slice of butter will be cut by the cutting mechanism


16


and released at the bottom of the base portion


62




b.






The strait gears


30


mesh with the top of the round gears


66


. The blade gears


58


mesh with the bottom of the round gears


66


. When the receptacle mechanism


12


is pulled towards the back of the frame


62


, the round gears


66


turn. The turning of the round gears


66


pushes the blade gears


58


forward. Because the blade gears


58


are attached to the cutting mechanism


16


, the blade


52


moves forward with the blade gears


58


. As the blade


52


is moving forward, the receptacle mechanism


12


moves the butter backward. This reduces the stroke length in half.




In an alternative embodiment, the blade


52


is formed such that the knock-off mechanism


56


is integral with the blade


52


. The blade


52


may be wedge-shaped. The wedge-shaped blade


52


is thicker which prevents bending of the blade


52


. The wedge-shaped blade


52


also provides the knock-off mechanism


56


to cause the butter to be knocked off the blade


52


.




Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize changes may be made in form and detail without departing from the spirit and scope of the invention.
