Fig. 17 is a perspective view of a modi fied form of wall block.

In the accompanying drawings, the ref erence numeral 2 denotes mold wall plates" and each plate is substantially rectangular in elevation and of sufiicient thickness to perm1t of said plates belng placed superposedrelation adjoining one anotherso as to form a mold wall. With two such Walls in spaced relation the intervening space may be filled wlth concrete 1 or other plastic material.

Each mold wall plate 2 has its upper edges; atits ends provided with notchesor recesses 8 and when the mold wall plates are placed in abutting assembled relation the recesses coiiperate 1n formmg transverse grooves or openings and the grooves 01" openingsof one mold wall are adapted to transversely al ne with thegroovesor openings of the other mold Wall.

Eachmold Wall plate ma haveitsouter race provided with blocks 22 and these blocks are preferably placed at the upper and loweredges of the plate, adjacent'the ends thereof so that the blocks of one plate will vertically ahne with the blocks of an adjoining plate, and the blocks atthehdges of the adjoining plates abut each other or approximately so, whereby such blocks may beconnected by a tie block 14. Eachof the blocks 22 has a tapered dovetailedtongue24 with thetongue disposedin a vertical plane intermediate the side edges of each block andthetongue tapers inwardly'toward the upper edge of a block so that it will be necessary to place the tie block 14 on the upper end. ofthe tongue and then shiftsaid tie block downwardly to connect the mold blocks. Thetorigues of themoldblocks at the upper edge of each mold plate are slightly larger than the tongues" of the weeks zit-the lower" edge ofthemold plateso that when the mold plates are placed in superposed relation the tongues at the upper edge of the mold plate will represent a continuation of the tongues at the lower edge of the adjacent mold plate. This will permit of the tie plate 14 being placed downwardly over the tongue 24 to connect all of the contiguous blocks, and in order that the tie plate 14 may be employed for this purpose, said tie plate has its inner face provided with tapered dovetailed grooves 21*. Each tie block is of a sufficient area to practically interlock four of the mold blocks 22 and to connect the mold blocks to the outer faces of the mold plates 2 I prefer to use screws or bolts 6 and nuts or sockets 2 both of which are shown in Figs. 15 and-.16.

. The bolt or screw 6 has a head 3* adapted to be countersunk in the inner wall of the mold wall plate 2, and the socket 2 has a nut portion 5 adapted to be countersunk in the mold blocks 22, so that the connecting means between the mold wall plates and the blocks will be flush therewith. Vith the sockets 2 permanently located in the blocks 22 the screw 6 may detachably support said blocks and should a block be injured it may be readily removed. 7

. Each tie block 14 has its lower edge provided with a transverse notch 19 adapted to register with the recesses 8 of the mold wall plates 2, so that said tie blocks may fit over transverse connecting members 10 'which are placed in the recesses 8 of the mold walls as the mold is built up. These connecting members are best shown in Figs. 1, 4 and 5 and each member is 1n the form of a bar that may be seated in the recesses 8 and extend from between the blocks 22 at the upper edges of adjoining mold wall plates. The side walls of each connecting member, at its ends, are provided with vertical grooves 7, and each groove may have its walls tapered or beveled to correspond to the taper "or bevel of the walls of the notches 19, so that each tie plate may be fitted down over the connecting member and becomeinterlocked therewith, thus binding the wall plate blocks 22 and the tie blocks to the connecting members which will prevent lateral displacement or bulging of the mold wall plates when assembled as a mold.

.As shownin Fig. 5 each connecting member may have its ends provided with additional grooves 7 and such grooves will serve two purposes. First, the mold walls may be placed a. greater distance apart should a widerwall be desired, or devices may be anchored on the ends of the connecting members tofacilitate assembling the mold parts, such devices forming no part of this invention.

Considering Fig. 1, it will be noted that the mold walls are tied together by the connecting members 10 and when walls are to be formed at an angle to one another I may use angular or curved tie blocks. An angular tie block 9 is shown in Fig. 9 and besides having its inner face provided with dovetailed grooves it has a notch 7 to receive the connecting member, and it is obvious that the recesses 8 will have the walls thereof beveled to aline with the walls of the notch 7 to permit of the connecting member extending in an angular direction relative to adjacent connecting members in the same lateral plane. This is best shown at the left hand side of Fig. 1, where the walls form an L. \Vhen the walls form a T, some of the connecting members 10 may have angular ends so that angle tie blocks 9 may be placed in engagement therewith.

A curved tie block 9 is shown in Fig. 13, and in constructing some concrete walls or curbings, it may be possible to provide a connecting member 40 with an angle tie block 9 and a triangular tie block 41, especially when a portion of a wall or curbing is disposed at an acute angle relative to an adjoining wall or curb portion.

Since some walls may have offset portions, tie blocks 23 may be employed as shown in Fig. 10 where one part of the block is of greater thickness than another part. This view of the drawing also shows that a tie block may have a tongue 24 at one end thereof and a groove 21 at the opposite end thereof, and the same is shown in connection with the angular tie block of Fig. 12, it being understood that mold blocks will be used having tongues to engage in the grooves 21 of the tie blocks. Such tongued mold blocks have been shown in Fig. 14 and designated 4. The mold block 4 may also have the inner faces thereof beveled or inclined and the tie blocks employed to interlock the mold blocks will be similarly formed, as brought out in Fig. 7, whereby the tie blocks will have a wedging action tending to tighten the mold blocks relative to the connecting members.

Since the mold wall plates may be of considerable length it may be necessary to use connecting members intermediate the ends thereof and such long mold plates are designated 26 in Fig. 2, and have the upper and lower edges thereof provided with single long blocks 21 which are used in lieu of two small mold blocks as at the adjoining edges of mold plates.

In some constructions it may be necessary for the mold blocks at the upper edges of mold plates to extend on to the lower edges of superposed wall plates, as shown in Fig. 4 and thus provide braces or guides for the upper mold wall plates when assembling the same. Then again, it is possible to use the long blocks 21 even at the juncture of a plurality of mold plates. It is in this connection that I do not care to limit myself to the precise size or shape of the mold wall blocks or even the tie blocks since diflerent kinds of concrete walls will require different kinds of molds.

It is obvious that the inner faces of the mold wall plates may be finished'to impart a desired finish to the exterior surfaces of the Wall, and after the parts of the mold have been removed the openings left by the connecting members may be plugged with concrete or otherwise closed.

What I claim is 1. The combination of mold plates adapted to be placed in superposed relation to form opposed mold walls, mold blocks carried by said plates at adjacent edges thereof, connecting members extending from one mold Wall to the other with the ends of said connecting members at said mold blocks, and tie blocks fitting on said mold blocks and said connecting members and holding adjacent mold blocks relative to said connecting members.

2. The combination set forth in claim 1, wherein the mold and tie blocks having tongue and groove connections and said tie ed to be placed in superposed abutting relation to form opposed mold Walls, said mold plates having the upper edges thereof recessed, mold blocks on said mold plates at the abutting edges thereof, connecting members extending from one mold wall to the other and protruding from said mold walls, said connecting members being seated in the recesses of said mold plates, and tie blocks fitted on said mold blocks and having the lower edges thereof notched to receive said connecting members, so that said mold and tie blocks are held against displacement relative to said connecting members.

4. The combination Set forth in claim 3, wherein said mold and tie blocks have tongue and groove connections.

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