This invention relates generally to caskets, and more particularly to a method of making one-piece, unitary lids for caskets by a novel molding process.
A casket includes a shell and, in the case of so-called “split top” caskets, a pair of lids or caps, a head end cap and a foot end cap. Caskets have most often been fabricated of either metal or wood for aesthetic reasons. More recently some lower end caskets have been fabricated out of materials such as plastic, hardboard, and cardboard. While such materials are much less expensive than sheet metal and fine furniture grade wood, there is a consequent decrease in the aesthetics of the casket. Thus, efforts continue to be made by those in the industry to devise more economically produced, less expensive caskets which do not exhibit a consequent decrease in aesthetics and ornamentality.
Each cap in a so-called split top casket is comprised of a crown, a pie, a rim, a header and, in the case of convex shaped lids, a web. More particularly, the crown is, as its name implies, the crown portion of the lid, which is often, though not necessarily, convex in shape. As its name implies, the pie is a pie-shaped section which fits into a pie-shaped cutout in one end of the crown. The crown and pie assembly is typically referred to in the industry as the “cover”. The cover thus has opposed sides and opposed ends. Each of the opposed sides has a decorative piece of molding known as a side rim member secured thereto. Similarly, the pie has secured thereto a decorative piece of molding known as an end rim member. The pair of side rim members and the end rim member together comprise the rim. At the end of the cover opposite from the pie, there is attached to the crown a web panel, and there is attached to the ends of the side rim members and to the lower edge of the web a header panel. In the case of flat top casket lids, there is no web, but simply a header. The term “header”, as used herein, shall be deemed to encompass both a) a header panel only, and b) a header panel in combination with a web panel. The combined assembly, i.e., crown, pie, rim and header, comprises the casket cap or casket lid.
In order to fabricate a cap, several different pieces must be time-consumingly assembled and secured together. For example, in the case of sheet metal caskets, a number of sheet metal stampings must be fixtured and then welded together to form the cap. In the case of wood caskets, the crown is formed from a plurality of boards secured together lengthwise with glue and fasteners. The pie is likewise formed from a plurality of boards and is secured to the crown with glue and fasteners. Next, the side and end rim members, themselves formed from a plurality of boards, are secured to the cover and the header is secured to the cover and the side rim members, again via glue and fasteners. As can be appreciated, utilizing a combination of glue and fasteners to secure together the various components of a wood casket cap is tedious and time consuming.
It would be desirable to reduce the number of component parts necessary to fabricate a cap thereby reducing assembly time and costs, etc. One attempt at accomplishing this, commercialized by Werzalit AG & Co., Federal Republic of Germany, involved the use of a mixture of wood chips and binder which was molded with tooling into a one-piece cover, i.e. crown and pie assembly. This molded one-piece cover thus eliminated the separate crown and pie and the steps required to secure the two together. The tooling for forming such a one-piece cover comprised a male portion configured into the shape of the under side of the cover to be formed, and a female portion configured into the shape of the upper side of the cover to be formed.
However, once this single-piece cover was formed, a manufacturer was still required to fabricate and install separate side rim members, end rim member and header to the one-piece cover in order to complete the cap assembly.
Another less than completely successful attempt at fabricating a one-piece casket cap utilized fiberglass and resin applied to a form in the shape of a casket cap, the process otherwise being known as “laying up.” While such a one-piece, integral fiberglass casket cap did include a crown, a pie, side rim members, end rim members and a header, the fiberglass material itself as well as its use created difficulties. For example, the process of laying up of fiberglass is time and labor intensive and does not readily lend itself to automation. Further, the glass fibers are difficult to manage and the resin produces noxious odors.
It would be desirable to eliminate even more of the separate component parts of a casket cap in order to eliminate the costs associated with producing the component parts as well as the costs associated with assembling together all of the component parts while at the same time avoiding the difficulties associated with fiberglass construction techniques.
The present invention is a method of making a one-piece, unitary lid for a casket and a casket lid made by the method. The method and lid of this invention completely eliminate the separate component parts required to be assembled together in prior casket lids. The method of the invention comprises providing tooling configured to produce a one-piece, unitary casket lid having a crown, a pie, a rim and a header, providing settable material from which to mold the lid, molding the settable material with the tooling and permitting the settable material to set thereby producing the one-piece, unitary casket lid having a crown, a pie, a rim and a header. A wood veneer sheet is adhesively applied to at least a portion of the lid.
The veneer sheet can be applied to the lid with either a membrane press or a profile wrapping machine. Preferably, glue is applied to the veneer sheet and the veneer sheet is adhered to the lid with the use of heat and pressure. The veneer sheet is preferably applied to the exterior surfaces of the crown, pie, rim and header.
In another aspect, a method for making a lid for a casket comprises providing tooling configured to produce a one-piece, unitary casket lid portion having a crown and a pie, providing settable material from which to mold the lid portion, molding the settable material with the tooling, permitting the settable material to set thereby producing a one-piece, unitary casket lid portion having a crown and a pie and adhesively applying wood veneer to the crown and the pie. A rim can be fabricated of solid wood and attached to the crown and pie, or a rim can be fabricated from a solid non-wood substrate profile wrapped with wood veneer, and attached to the crown and pie.
In another aspect, a method of making a lid for a casket comprises providing tooling configured to produce a one-piece, unitary casket lid portion having a crown and a pair of side rims, providing settable material from which to mold the lid portion, molding the settable material with the tooling, permitting the settable material to set thereby producing a one-piece, unitary casket lid portion having a crown and a pair of side rims and adhesively applying wood veneer to the crown and side rims. A pie and end rim can be fabricated of solid wood and attached to the crown and side rims.
In another aspect, a method of making a lid for a casket comprises providing tooling configured to produce a one-piece unitary casket lid having a crown, a pie, a pair of side rims, an end rim and a header, providing settable material from which to mold the lid, molding the settable material with the tooling, permitting the settable material to set thereby producing a one-piece, unitary casket lid having a crown, a pie, a pair of side rims, an end rim and a header, separating a pie and end rim from the crown and the side rims, adhesively applying a first wood veneer sheet to the pie and end rim, adhesively applying a second wood veneer sheet to the crown and side rims and attaching the veneered pie and end rim to the veneered crown and side rims.
In another aspect, for a casket lid having a pie and a crown, a method of forming a miter joint from first and second sheets of veneer applied to the pie and crown, along the line of intersection of the pie and crown, comprises applying a first strip of masking tape to the line of intersection, trimming the first strip of masking tape along the line of intersection and removing the trimmed portion from the pie side of the line of intersection, applying a first sheet of veneer to the pie, the sheet overlying the portion of the first strip of masking tape remaining on the crown side of the line of intersection, applying a second strip of masking tape to the first sheet of veneer over the line of intersection, trimming the second strip of masking tape and the first sheet of veneer along the line of intersection and removing the trimmed portions from the crown side of the line of intersection by removing the portion of the first strip of masking tape remaining on the crown side of the line of intersection, applying a second sheet of veneer on the crown, the sheet overlying the portion of the second strip of masking tape remaining on the pie side of the line of intersection and trimming the second sheet of veneer along the line of intersection and removing the trimmed portion from the pie side of the line of intersection by removing the portion of the second strip of masking tape remaining on the pie side of the line of intersection.
In another aspect, a method of making a head end lid and a foot end lid for a casket comprises providing tooling configured to produce a one-piece, unitary casket lid having a crown, a pie, a rim and a header, providing settable material from which to mold the lid, molding the settable material with the tooling, permitting the settable material to set thereby producing a first one-piece, unitary casket lid having a crown, a pie, a rim and a header, repeating the above steps to produce a second such casket lid, positioning the first and second lids header-end-to-header end, adhesively applying a single wood veneer sheet to the crowns of both the first and second lids and separating the first lid from the second lid. The veneer sheet can applied to the lids with a membrane press.
The invention thus provides a method of producing a molded one-piece, unitary lid for a casket which includes a crown, a pie, a rim and a header. Multiple components are not required to be fabricated or assembled. The invention also provides methods of applying decorative veneer to the molded one-piece unitary lid.
These and other advantages of the present invention will become more readily apparent during the following detailed description taken in conjunction with the drawings herein, in which:

The invention thus provides a one-piece, unitary lid for a casket which includes a crown, a pie, a rim and header: separate fabrication and assembly of individual components are thus eliminated. The lid includes a decorative wood grain pattern applied thereto. The paper covering forming an outer skin of the lid conceals the wood chips in the material from which the lid is formed and may be attractively stained to further enhance the wood look. And, when two lids are placed end-to-end atop a casket shell the wood grain is continuous from the head end to the foot end of the lids thus presenting the appearance of lids fabricated from so-called full length boards.
The invention may also be practiced in conjunction with the application of wood veneer to the surface of the molded lid 20. The veneer can be applied to either the entire lid 20 all at once (whether for a full length cap or for a split cap), or to portions of the lid 20 in a series of steps. In addition, a combination of wood veneer applied to selected portions of the molded lid 20, in combination with either solid wood lid portions or wood veneered solid non-wood (fiberglass, plastic, etc.) lid portions, can be used to fabricate the lid 20. In addition, the wood veneer can be applied to other portions of a casket other than just the lid, for example the casket shell side walls, end walls, top mold, base mold, etc. In those cases, the underlying structure to which the veneer is applied can either be a molded product molded by the steps above, or other material such as medium density fiberboard, timber core (also known as oriented strand board), particle board, fiberglass, or plastic, for example. While the step of applying the veneer will be described below in the context of utilizing either a membrane press or a profile wrapping machine, it is to be appreciated that the veneer could be applied to the underlying substrate by other techniques and still be within the spirit and scope of the invention.
In a presently preferred method of practicing the invention in conjunction with wood veneer, and referring now to
The pie 24 and end rim 36 of the lid 20 are then veneered. A precut (e.g. with a laser cutting device) sheet of approximately 0.025 inch thick wood veneer 24a has glue applied to it (e.g. with a stationary glue wheel over which the sheet of wood veneer 24a is run). The glue is preferably a cross-linking PVA such as that marketed by Franklin Adhesives as Multibond MX90. The sheet of wood veneer 24a is then placed on the pie 24 and end rim 36 of the lid 20. The lid 20 with wood veneer 24a applied to the pie 24 and end rim 36 thereof is then placed in a “membrane press” 10a, a press which utilizes a silicone rubber membrane 11 to conform the veneer to the profile of the lid 20, and heat and pressure are applied to one side of the lid 20 by one side 12a of the press 10a, while a vacuum can be (though is not necessarily) applied to the other side of the lid 20 by the other side 14a of the press 10a. The lid 20 is then removed from the press 10a, and the excess wood veneer is trimmed from the end rim edge and miters of the pie veneer 24a. The process is then repeated with crown veneer 22a for the crown 22 and side rim members 34.
In order for the miter where the pie veneer 24a and crown veneer 22a meet to have the proper aesthetics, the following procedure is employed. Prior to applying the glue laden veneer 24a to the pie 24 and end rim 36, tape 100 is applied to the bare lid 20 along the miters where the pie 24 intersects the crown 22. The tape 100 is preferably a high temperature masking tape such as that marketed by 3M as either 4737T or 2364. The tape 100 is then trimmed precisely by an automated trimming machine 104 along its respective miter, and the tape portion 100a on the pie 24 side of the miter is pulled up and removed, leaving just the tape portion 100b on the crown 22 side. The precut veneer 24a to be applied to the pie 24 and end rim 36 is sized so as to overhang the miters and end rim slightly. The glue laden pie veneer 24a is then applied to the pie 24 and end rim 36, and the cover 26 is placed into the membrane press 10a for about 30 to 120 seconds at a press temperature of about 340 degrees F. (which produces a glue temperature of about 180 to 210 degrees F.) and a press pressure of about 60 psi, and is then removed. Next a second piece of tape 102 is applied to the pie veneer 24a and to the bare crown 22 along the miters. The excess pie veneer 24a′ is trimmed precisely by the trimming machine 104 along the miters. The excess veneer overhanging the bottom edge of the end rim 36 is also trimmed away, and can be done so manually. The tape portion 100b on the crown 22 side of the miter lines is then pulled up and removed, removing with it the excess pie veneer 24a′ as well as tape portion 102b, leaving just tape portion 102a on the pie 24 side of the miter lines and overlying the pie veneer 24a.
The precut veneer 22a to be applied to the crown 22 is also sized so as to overhang the miters and side rims 34 slightly. The glue laden crown veneer 22a is then applied to the crown 22 and the cover 26 is again placed in the membrane press 10a at the pressure and temperature, and for the duration, mentioned above. The cover 26 is then removed from the membrane press 10a and the excess crown veneer 22a′ is trimmed precisely by the trimming machine 104 along the miters. The excess veneer overhanging the bottom edges of the side rims 34 and header 32 is also trimmed away, and can be done so manually. The tape portion 102b remaining on the pie 24 side of the miter lines and overlying the pie veneer 24a is then pulled up and removed, removing with it the excess crown veneer 22a′.
In the production of split caps or lids, it is particularly advantageous to perform the pressing step with 2 lids 20 oriented header-to-header and spaced slightly apart, in the press 10a. In that case a sheet of crown veneer 22a long enough to cover both crowns 22 of both lids 20 is used. During the laser cutting step of cutting out such a length of crown veneer 22a, perforations 23 are formed in the crown veneer 22a at its mid-length point; during the pressing step the membrane press 10a tears the veneer sheet along the perforations. See
Finally, a roller is applied to the abutting edges of the pie veneer 24a and crown veneer 22a, i.e. along the miters, to assist in producing a smooth, even and aesthetically pleasing transition between the two veneer sheets.
An alternative to the membrane press 10a for conforming the veneer to the casket lid or to selected portions thereof, or to other portions of the casket, is to use the technique of “profile wrapping.” See for example U.S. Pat. Nos. 5,234,519 and 3,541,592, both of which are hereby incorporated by reference herein as if fully set forth in their entirety. As shown in
Various combinations and permutations of the above can also be practiced. For example, only the cover portion 26 of the lid 20 could be molded by the principles of the invention. Then solid wood side and end rim members 34, 36 could be attached to the cover 26 with glue and/or fasteners. The cover 26 could be veneered as described above either before or after attachment of the rim members 34, 36. Alternatively, the rim members could be fabricated by profile wrapping veneer onto a solid non-wood substrate. Further, the entire lid 20 could be molded as described above, and then the pie 24 and end rim 36 could be cut out of the lid 20. The pie 24 and end rim 36 could be veneered in one step, and the crown 22 and side rims 34 could be veneered in another step; once both are veneered the two could be assembled with glue and/or fasteners. Still further, just the crown 22 and side rims 34 could be molded as described above, and a pie 24 and end rim 36 could be fabricated out of solid wood and attached to the crown 22 and side rims 34 with glue and/or fasteners.
Other variations are as follows. The lid 20 could be pressed with crown veneer 22a applied to the crown 22 and side rims 34, and then the veneer 22a could be trimmed as described above. Then a perfectly laser cut pie veneer 24a could be pressed onto the pie 24 and end rim 36, thus requiring no trimming of the pie veneer 24a. Or, the lid 20 could be pressed with pie veneer 24a applied to the pie 24 and end rim 36, and then the veneer 24a could be trimmed as described above. Then a perfectly laser cut crown veneer 22a could pressed onto the crown 22 and side rims 34, thus requiring no trimming of the crown veneer 22a. Or, both the pie veneer 24a and the crown veneer 22a could be perfectly laser cut and then pressed onto the lid 20, thus requiring no trimming of either.
Further, and referring now to
“Marquetry” is a decorative veneer sheet which is assembled from many separate individual pieces/colors/designs of veneer to produce an intricate pattern and when applied to a substrate resembles an “inlay.” Marquetry is especially appropriate as the veneer to apply to the molded lid 20 of this invention as the resulting casket lid gives the appearance of being finely tooled and decoratively inlaid. Other variations on the veneer aspect of the invention can include running the sheet of veneer through an ink jet printer to apply an ink pattern to the veneer, and then applying the veneer sheet to the casket lid. Or, the veneer sheet could be laser engraved with designs and/or text prior to applying it to the casket lid.
Those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the present invention which will result in an improved casket lid and method for making, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. For example, the method of this invention readily lends itself to fabricating lids for so-called full-couch caskets, i.e. caskets which have a single full-length lid rather than a pair of so-called split caps. In that case, the lid does not have a header on one end. Rather, the lid includes a full-length crown, a pie at each end of the crown, a pair of side rim members one of which is at each side of the crown and a pair of end rim members one of which is at each pie. Further, even though the material to be molded is described and illustrated as being applied to the male tool prior to molding the material, it is to be understood that the material could just as well be applied to the female tool instead, or be applied to both the male and female tools prior to molding the material. In addition, fibrous materials other than those mentioned above may be utilized in the practice of the present invention; for example, plastic chips may be used. Further, wood veneer can be utilized as a covering for the molded cap. Still further, a thermal transfer layer, i.e. a sheet with ink printed thereon, could be used to place an ink pattern on the molded cap. Still further, a flange, such as an extruded plastic flange, could be attached to the cap for securing a dish assembly in the cap interior. Or alternatively a flange could be molded directly into the cap thus providing an integral means of securing the dish assembly within the cap. Thus, the invention shall embrace all such variations. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
