METHOD OF MAKING COMPOSITION BURlAL-CASKETS.

SPECIFICATION forming part of Letters Patent No. 536,749, dated April 2, 1895.

Application filed March 28. 1893. Renewed September 11, 1894. Serial No, 522,753. (No model.)

To all whom it may concern.-

Be it known that I, HENRY A. GARVEY, a citizen of the United States, and a resident of the city of New York, in the county and State of New York, have invented new and useful Improvements in Methods of Making Composition Burial-Caskets, of which the following 1s a specification.

My invention relates to a method of forming hollow articles formed of compositions of matter and having metallic cores, and consists of the methods hereinafter described and is more particularly pointed out in the claims concluding this specification.

One form of my invention is illustrated in the accompanying drawings, forming part of this specification, in which- Figure 1 is a cross-section of the mold and casket. Fig. 2 is a longitudinal section of the Fig. 3 is a'plan sectional view taken on line 55 of Fig. 2. Fig. 4 is a view of a part of the mold. Fig. 5 is a section of the lid, and Fig. 6 is a section of the body of the preferred form of the casket formed according to my invention, also showing part of the mold. Fig. 7 is an edge view of the preferred form of the foraminous core, and Fig. 8 is a side view of the same.

My invention, so far as it relates to the method, is as followsz-About or in one part of the mold, I stretch a foraminous metallic templet, provided with small spurs or ofi-sets to hold the same away therefrom, so that, by preference, it will be in the center of the completed mold. I then secure the edges of the templet by means of small wires or the like to the mold, preferably placing them in shallow grooves across the face thereof. I then place and secure the other part of the mold in position. Then I introduce the liquid or plastic composition through suitable gates,

leaving others as air-vents, until the mold is full. I allow a sufficient time for the hardening or setting of the composition to elapse. Then I remove the mold, cutting the small holding wires after taking off one part of the mold. The top is formed in a similar manner. The parts are now ready for subsequent operations, such as smoothing off, painting, affixing of handles and the like.

In some cases, I roughen or oxidize the core to get a better bond between it and the composition.

Referring to Figs. 1 to 4 of the drawings, 5 marks one half of a mold, said half 5 being formed of four longitudinal pieces 6, 7, 8, 9, hinged together by hinges 10, and three pieces (at each end) 11, 12, 13, held in place by overlapping lugs 14 and screws 15. The pieces 6, 9,11, 12, 13, of the half mold 5 are formed with flanges 16, which have lugs or flanges 17 in which screw threaded bolts 18 are pivoted, said bolts having butterfly nuts 19 thereon.

At suitable intervals, the flanges 16 have small holes 20 through them. I-Ialf mold 5 by preference is suspended at a height convenient for workmen, (or it may be turned upside down on a bench,) while the templet or core is put in position.

The core 4 is preferably cut from wire cloth (or equivalent) of a width sufficient to extend around parts 6, 7, 8, 9, of half mold 5 from flange to flange (16), the ends being cut into gores. In some cases, small off-sets or spurs 21 are secured to the core at intervals for a purpose hereinafter mentioned. These spurs 21 are rnade of the material used for the casket and may be fastened in place by any suitable means. The core is then bent or stretched around the half-mold 5 with its spurs thereagainst to hold the core away therefrom. The gores are brought up with their edges together or overlapping and are laced together with wire or otherwise secured. The edges of the core are secured to the mold by small soft or flexible wires 22 which pass through holes 20 in the mold and are fastened to the core, and then to pins on the inside of the mold when the core is sufficiently taut.

The outer half mold which is formed of bottom piece 24, side pieces 25, and end pieces 26, hinged to bottom 24, is placed under the suspended half mold 5 withthe sides and ends down. Half mold 5 with core 4 in place is lowered and centered until the sides and ends of the outer half mold can be brought up and bolts 18 be placed in slots 27 in the overlapping edges of the sides and ends 26. By means of the bolts 18 and nuts 19, the molds are brought into proper relation with each other, (the core 4 being mid-way between them) and there secured. The fluid or plastic composition is then introduced through some of the gates 28 until the mold is entirely full. The composition fills all interstices of the mold and core, the two parts of the article separated by the core 4 being united through the perforations in the latter; also, owing to the oxidized condition of the core, forming a good bond with the same.

After allowing the mass to set or harden,

the sides 25 and ends 26 are dropped,b0lts 18' and nuts 19 being loosened for that purpose, screws 15 are removed, parts 11, 12,13 are removed, then pieces 6, 7, 8, 9, are likewise removed, and then the casket 2 is lifted from the bottom 24, and is ready for the finishing operations. Rough places on the casket are next smoothed otf, and the same may be painted or otherwise finished by steps not necessary to be stated here.

The top is formed in a similar manner with a core 4? therein, and with rabbeted edges 31, so as to fit against and overlap the edge of the body portion of the casket, to which it is secured, as by screws. The casket is supported on legs or flanges 33 made integral therewith.

Thecasket maybe upholstered and finished as desired. The metal core imparts rigidity and strength to the casket.

In Figs. 5 to 8 inclusive I showa preferred form of the casket and the foramonious metallic core. The latterconsists of wire netting 4, havlng out portions or spurt 21, at suitable intervals, said spurs 21 being turned to about right angles with the netting. I find that a one-half inch mesh wire netting answers very well, with the spurs several inches apart. (In the drawings, these are shown as relatively closer than this to accommodate mat ters to the size of the drawings.)

The cores, in Figs. 5 and 6, are shown with outwardly and reverse flanges and 41. These give great stiffness to the edges of the casket and cover. In addition there may be longitudinalbeads or moldings, as42, 4.3 on the casket and cover, as wellas ornamentation.

For the best results the mold should have a smooth or polished surface for contact with the plastic composition. A metallic mold with burnished surfaces does very well for this purpose. The use of a mold with smooth faces gives a smooth surface to the articles ready to receive varnish, paint, or other finish.

It will be understood that the method hereinbefore described may be used to form hollow articles of many descriptions.

Any suitable composition of matter, as artificial stone, cement, plastic compositions, &c., may be used to form the articles in combination with the core.

What I claim as new, and desire to secure by Letters Patent, is-- 1. The method of making artificial stone caskets consisting in forming or bending a foraminous metallic core, provided with indicators or spurs, upon one part of a mold with the spurs thereagainst, fastening the edges of the core to the mold, placing the rest of the mold in position, then filling the mold with the fluid or plastic composition of matter, allowing the same to harden, then releasing and removing the mold, substantially as described.

2. The method of making artificial stone caskets consisting in cutting and bending some of the wires of a netting at points to form spurs, bending the netting about one part of a mold with the spurs thereagainst, securing the edges of the netting to the mold, placing the rest of the mold in position, filling the mold with the fluid or plastic composition of matter, allowing the same to harden, then releasing and removing the mold, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name,in presence of two witnesses, this 22d day of March, 1893.

HENRY A. GARVEY.
