APPLICATION FILED AUG. 20, 1908.

2 T E E !H 2% m N w +U m a D1 side plates 11 of the mold is formed the mold cavity, in which the concrete material 150 is placed. The lower inside plates 11 are so adjusted by means of the bolts 9, that their flanges 120 rest a distance above the floor 2, equal to the thickness it is desired to give to the bottom of the concrete vault or receptacle, the whole inside being sup ported by the cross beams 13, as above described. When the concrete is poured in through the open top 15 of the mold, it is allowed to rise until it reaches these flanges 120, when the concrete is then poured into .the mold cavity between the inner and outer plates, until it reaches nearly to the top of said cavity.- By the time the mold cavity is thus formed, the bottom may be struck oil, or leveled, using the flanges 120 as guides to "determine the final thickness of said bottom. After this is donepthe concrete will be sufliciently solid to support the side plates 11- and to permit the removal of the supporting beams 13.

The rabbet forming strips :17 may now be placed in the mold cavity, and the concrete filled up-to the top of the latter and smoothed off; or these strips may be placed in said cavity at any earlier stage and suit-ably supported from the outside.- When the strips 17 are removed a rabbet 151 Will be formed in the finished receptacle 150, as shown in Fig. 6, which latter is obtained by disassembling the parts of the mold after the con; crete has sufiiciently hardened.

The operation of the form or mold will be clear from the above, but itmay be summed, up as follows :VVhen it is desired to assemble the mold, the floor- 2, it a floor is to be used, is first brought into position; the outer and inner plates are so adjusted the one over the other as to form a mold cavity having any desired inside ancl outside dimensions and said plates are firmly secured togetherby means of the bolts 9; the

longitudinal upper and lower outside supporting bars are brought into poslt-ion, and the outside end bars are secured thereto by 'means of the bolts 302 passing through the proper holes in said bars. The uprights 1-.

are secured over said outside bars after the ns de plates have been brought into position inside said outside plates. The inside strips 18 and21 and the adjustable Spreaders l!) and 20 are brought into place, and the whole inside wall of the mold cavity suspended. by the cross bars 13, as above described.

The flanges 12,120 and 130 are important-- features of this invention, for they serveto; stiifen the plates as above stated, and thereby permit them to be made so light that.

they can for ordinary burial vaults be handled by one man by hand. And the flanges 120, are an additional especially important feature of this invention, for not only do they secure the necessary strength above described, but they support the plates on the concrete while it sets, and constitute a convenient and ready gage by which the workman may at once know'the thickness of the bottom of the vault and may level it off without any delay Whatever.

After the vault is formed in the manner above set forth, the form or mold 60, shown in Fig. 5, may be used to form the. finished cover 70, shown in Fig. 7, which is preferably provided with the handles 71 before the concrete sets.

Various changes coming within the spirit of this invention will readily suggest themselves to those skilled in the art, and therefore I do not wish to be limited to the exact details of construction, except as specified in the claims.

What I claim is V 1. Ina form or mold for concrete receptacles, the combination oftelescoping inner and outer side and end walls flanged at their In a foian or mold for concrete recep- 'tacles, the combination of telescoping inner and outer side and end walls flanged at their top edges and provided with registering holes, and bolts adapted to secure said sides together; telescoping upper and lower outer side and endsupporting bars, also provided with registering holes; two pairs of horizontal supporting strips 18 and onepair of vertical strips 2-1 adapted to rest on the inside of said inner Walls; and adjustable spreader bars 19 and 20 adapted to extend between said strips, substantially as described.

3, In a form or mold for concrete recep' tacles, the combination of perforated inner. and outer adjustable telescoping plates pro: vided with stitlcning flanges at the upper edges; means comprising bolts for holding said plates in their adjusted positions; cross bars 13 extending across and resting on the upper-flanges of said outer plates; and bolts passing through said bars and.the flanges of said inner plates and serving to support the "same above the bottoms of said outer plates,

flanges; means passing through said beams adapted to hold the bottom, flanges of said inner plates a predetermined distance above the bottom edges of the outer plates; andadjustable- Spreaders inside said inner plates substantially as described.

5. In a form or mold for concrete receptacles, the combination of inner adjustable telescoping plates provided with registering holes and flanges on their top and bottom edges; outer plates also provided with registering holes and flanges on their top edges; cross beams adapted to rest on said latter flanges; means passing throu 'h said beams adapted to hold the bottom ianges of said inner plates a predetermined distance above the bottom edges of the'outer plates; horizontal strips 18, and vertical strips 21 adapted to contact with said inner plates; and adjustable spreaders inside said inner plates adapted to contact with said strips, substantially as described.

(3. In a form or mold for concrete receptacles, the combination of inner and outer adjustable telescoping plates provided with stiffening flanges at their upper edges, and

said inner plates provided. with stiffening flanges at their lower edges; a bottom for said mold; cross beams 13 adapted to rest on the upper flanges of said outer plates and provided with means whereby the lower flanges of said inner plates are supported a predetermined distance above said bottom;

and inner and outer means for holding said plates in position, substantially as described.

7. In a form or mold for concrete receptacles, the combination of inner and outer adjustable telescopin plates provided with registering holes, stit fening flanges at.- their uppenedges and-said inner plates provided with stiffening flanges at their lower edges;

a bottom for said mold; cross beams 13 provided with recesses fitting and adapted'to,

bars on the outside of said mold and spreader bars on the inside of the same, substantially as described.

8. In a form or mold for concrete receptacles, the combination of inner platesfianged at their bottom edges; outer adjustable telescoping plates flanged at their upper edges and provided with registering holes; bolts passing through said holes adapted to hold said plates in their adjusted positions; outer, upper and lower supporting side and end bars also provided with registering holes; a bottom for said mold; vertical braces st through which said supporting side plates pass; an adjustable rod passing through said vertical braces; cross bars provided with reeesses fitting the flanges of said outer plates and provided with means for holding the flanges of said inner plates a predetermined distance above said bottom; two pairs of horizontal strips 18 fitting the inside of said inner plates; and vertical. strips 21, also. fitting the inside of said inner plates; and adjustable Spreaders contacting with said strips, substantially as described.

In testimony whereof, I aflix my signature. in presence of two witnesses.
