Moto FOR BURIAL-CASES.

SPECIFICATION formingpart of Letters Patent No. 275,004, dated April 3, 1883.

(No model.)

To all whom it muy concern:

Be it known that I, CHARLES E. WILSON, a citizen of the United States'of America, residing at Hyde Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Molds for Burial-Gases, of which the following is a specification.

This invention relates to the casting of burial-cases or coffins in an upright position so as to lessen the labor and time required, and obviate the liability of damage attending the turning of the molds and casket after said casket is completed, as is necessary when the casket is cast in an inverted position.

The objects of ymy invention are to provide the inner surface of the casket or coffin with corrugations or depressions for the purpose of reducing the weight without unduly aifecting the strength ofthe casket; also, to provide a core for the outer mold; so constructed and arranged as to produce the said corrugations or depressions, and at the same time be capable of being readily'withdrawn when the casket is completed; and, further, to provide the upper edge of the Acasket with pieces or strips of metal of a peculiar form to hold the lid-fastening screws and to give strength and stiffness to that part of the casket. i

The invention consists in certain pccularitiesY in the construction, arrangement, and combination of parts, as hereinafter more fully described and claimed.

In the annexed drawings, illustrating the in vention, Figure `1 is a plan view of a mold for molding coffins in an upright position.

Fig. 2`is a cross-sectional view of the same taken on the line xwin Fig. 1. Fig?) is a cross sectional view of a coin completed; and Figs. 4, 5, and 6 are detail views to be referred to hereinafter.

Similar letters of reference refer to like parts throughout the several views.

A A is the mold, which may be constructed of wood, iron, or any'other suitable material.

B is the base-plate or bottom part oi' `the mold, and should be made sufficiently larger than the casket to admit of the sideand end walls or outer shell of the mold to restupofn it, and it may be provided with` wa'lls or ledges a ct, equal in height to the desired thickness of Vthe bottom of the casket, thus forming a gage to regulate the thickness of the cement as desired.

spread on the base-plate, as and for the purpose hereinafter more fully set forth,` or it may be merely a plain surface of the required size.

In casting coffms of this class in an upright position the core or inner shell of the mold may be made of suitable material and left in to form a part of the completed casket, or it maybe made to be withdrawn in the usual manner, and may be made in sections, or not, When intended to be withdrawn there are, however, manyreasons why a core in sections and collapsible should be preferred. A case so constructed facilitates to a greater degree the process of llling in the cement, is more easily and quickly removed, and it is only by the use of such a core that the inner surface of the core may be provided with corrugations, or with indentures to correspond with projections on the outer surface, which is` sometimes desirable.

I make the core C in two or more sections s s', die., as shown in Fig. 2, the bottom one, s, of which may be a plain-surfaced board or plate, or may have side wall, a a', as shown, and be provided with openings o o, supplied with corresponding pieces, o', for the purpose of removing the surplus cement from the bottom, should too much be spread thereon, in the manner hereinafter more fully described. The upper sections, s', .&c., have plain boards or plates b for the side walls, and have their ends composed of two pieces, b and h2, hinged at either side to the side pieces, b, in such a manner that they may be folded back parallel with the side pieces, I), as shown in dotted lines in Fig. 1. The end pieces, b' b2, are held in position by a bar, b3, secured to one of the parts andiitting over staples c in the other, a pin, p, being used to secure them.

The outer shell, A A, of my mold ll make in a similar manner to those already in use, composed of the side pieces, c c', and end pieces, d d, held together at the ends by swinging clamps D, composed of two parts, ce', connected by a coupling, e?, provided with right and left threads and hinged at one end to one side piece, c', and provided at the other end with a head, c3, which slips into a slot provided for the purpose on the outside face of the other side piece.

For supporting the core C in position in the mold, combination pins or screws may be used,

which go down through ,the bottom of the core and through the cement into holes provided in the base-plate for them; or these pins or screws may go, `through the sides of the core into the side walls of the outer shell. 1v however prefer screws made as shown at E, Figs. 2 and 4, composed of two parts,ff, the lower part,f, of which screws into the baseplate B, and when screwed in to its llimits projects above the said plate B a distance equal to the thickness of the bottom of the casket to be made. rihe upper part, j", passes through the bottom ofthe core C and screws into the lower part,f, which is tapped to receive it, the core G resting on and being supported by the lower part,f.

My method of casting a burial-case is as follows: I rst spread a thin layer of cement on the base-plate B, then lay upon that a sheet ot' perforated metal, wire-cloth, or other material intended to strengthen. the coffin-walls. rlhis sheet may be ofthe exact size of the bottom of the core, or larger, and turned out at the edges to lap up around the side walls some distance, and so arranged that it will be embedded within lthe walls of the cement when the casket is completed. Another layer of cement is then added sufficient to make the required thickness ofthe bottom of the coffin. The bottom section of the core (or if not made in sections the whole core) is then placed in position upon the screws E and fastened, as before described. It' there should be a surplus of cement on the bottom plate, B, the pieces 0 are removed from the openings o in the bottom ofthe core (l and the surplus cement allowed to ooze up through said openings as the core is forced down into its position, after which the surplus cement, if any, is removed and the pieces o replaced. A thin layer of cement having been spread on the side and end walls of the outer shell, and sheets of per forated metal or equivalent placed upon them, as before described for the bottom,they are set up in position and held in place at the bottom by projections upon the outer edge of the base-plate, or by double pins, as shown, and are clamped at the end by clamps D by turning the right-andleftthread coupling` e?. A space between the outer walls and the core still remains to be filled, which is done by pouring or tamping in the cement to the height of the bottom section of the core. The second section is then placed on the first and held in position by double pins, or otherwise, at the sides, andthe cement again lled in around it, and so on, if more than two sections are used. When the last section is placed in position and cement putin until near the top, a strip or strips of perforated metal, wire-cloth, or similar material, in a corrugated form, as shown in Fig. 6,is slipped into the cement until thetop edge comes dush with the top edge of the completed casket. vIhe pieces of metal a, designed to hold the lid-fastening screws, and provided with projections a', (see Fig. 5,) which serve as anchors to hold them firmly in the cement,

and also serve as guides to secure their coming in the center of the walls by extending on either side to the shell of the mold, are then placed in position at the proper places and cementis lled in until the mold is full,the top edges of the core and outer shell being exactly on a line.

If desired,the corrugated metal or wire-cloth may be dispensed with and the strips a be employed alone. In this case the metallic strips or pieces n, provided with projections, as described, may be made of sufficient length to go around the whole casket, and thus serve the double purpose of providing an attachment for the lid-fastening screws, and also of giving stiffness to the walls of the casket, and so avoid the use of the corrugated metal or wire-cloth, and at the Same time prevent any liability to warping or springing of the upper edges of the side walls.

After the cement is set the core is extracted by folding in the ends of the collapsible sections, as before described, and removingthem one at a time,the bottom section beingjarred loose and lifted out last, the screws E in the bottom being first removed. The clamps D are then loosened and the walls of the outerv shell removed, after which the holes left by the screws E are filled up with cement and the casket is completed.

If it is desired to embed askeleton frame of iron and wood strips into the casket to add further to its strength,a11d to provide for support for the screws whichfasten on thehandles, such frame is placed in position upon the rst layer of cement spread on the base-plate B, the subsequent proceedings being as described.

Having thus described my invention, what I claim as new, and desire to secure by vLetters Patent, is-
