' ing' is a specification.

The object of our invention is to produce a mold for making receptacles, such as burial- Vaults, from a plastic material, such as 'cementsconcrete,jthe construction being such that the mold may be readily adjusted so as to permit the formation of two-piece receptomes ofdifl'erent lengths and widths.

The accompanying drawings illustrate our invention.

Figure l is a perspective view of our mold in assembledposition for the smallest size; Fig. 2, a perspective view of the form for molding the cover-section; Fig. 3, a pore ective View of the external mold extende for one of the lar er sizes Fig. 4, a similar View of the interna core similarly extended, and Fig. 5 is a transverse section ofthe coverforming" mold.

The external mold is formed of bshaped members 10, each of which, at its corner, is )rovided witlrcne or more corner-pieces l1, termed, preferably, of anglcdron suitably bent into an t. and secured. thereto. Secured to each arm of each bracket is bar 12 extended along the adjacent arm or the L-shaped secfiion forming the mold side, the outer free ends of these bars overlapping and being connccted in ditl'erent longitudinal adjustments by suitable bolts 1.3. Adjacent arms of adjacent mold members 10 are laterally displaced slightly in opposite directions, so that they may be overlapped, as shown at X, one of the. mold-section arms lying a sufficient distance from be adjacent bar 12 to permit the oven lap ing mold-section arm to pass between it and the adjacent bar. By this means it is possible by loosening the several bolts 13 to collapse or expand the box-like mold form of the four L-sha )GCl sections without the removal or introduction of fillin members to complete the sides of the mold. The mold sides are formed, preferably, of sheet motel which isflcomperatively thin, and the lateral displacement of the overlapping sides docs are adjustably secured by bolts 31.

notcxceed one-half the thickness, so that the oll'sets formed in the face of the concrete are not great and may be readily troweled out at thetime when the mold is removed.

The core member is formed, substantially like the external mold member, of four L' shaped well-sections 20, having secured at their inner corner Lshaped braces 21, to each arm of which is secured a bar 22, the adjacent ends of which overlap and are adjustably connected. by bolts The adjacent arms of the L shaped core sides 20 overla as at X. The top or cover of the van t may be form ed in a mold composed of four L-shap ed members 30, the arms of which overlap and Each member 30, in cross-section, is composed of a vertical arni32 and an inclined arm 33, the inner angle between the two being obtuse. Any size cover may be readily obtained by loosening the bolts 31 and slidin the several members 30 on each other until the dimensions are obtained,

in operation the mold members 10 arsed-- justed upon each other without the use of filler members, so as to form a box of the reuired dimensions, end a floor of concrete is ,t on laid in the bottom thereof, the mold beplaced Within the external mold, and the space between the two molds is filled with plastic.

The cover; mold similarly adjusted and placed, with the arms down, upon a suitable foundation{date and filled with concrete. i l/hen the concrete has sufficiently set, bolts may be loosened and the core slightlycollapsed by moving the L-shaped secti0ns 20 together, whereupon t 1e core ma be easilywithdrawn. T he shallow vertica creases in the concrete may be then readily troweled out. The exterior mold is then removed by loosening bolts '13 and slightly separating the members 10, whereupon the structure may be lifted-ell from the completed vaultl The members 12 or 22 are firmly attached to theirsupporting corner-pieces and to each other, and thus securely brace the overlapping. arms of the mold-forming members.

Vi e claim as our invention-- 1. A mold comprising four Lshaped sidefOimlfif members the as scent ends of which overlain, corner-pieces secured to the corners earners of each of said members and having portions standing along the side-forming members with their adjacent ends overlain ping, and means for Pdjustahly'securing said overiavpping ends together.

A mold comprising a. pair of nested boxlike members each comprising four L-shsped side-iorn'nng members the ad acent ends of wh ch overlap, corner-p1eees seem'ml to the l corners of each of said members and having i portions standing along the side-forining members with their adjacent ends overlapping, means for sdjustably securing said overlapping ends together, and a eover forining mold com I rising four L-sha-ped members the arms of W iich are overlapped, and means for connecting said overlapping arms at different points of adjustment.

In Witness whereof i have hereunto set my hand and seal, at Linton, indiana. this 21st. day of July, A. D. 1906.
