Patented Sept. 18, 1906.

.To avZZrwhoz/h/it may concern:

Be it known that I, JOHN G. voN Horn, a citizen of the United States, and a resident ofthe city of New York, borough of Manhatmasses of concrete or other plastic material..

Certain other objects are also. involved, and they will appear below.

Reference is to be hadv to the accompanying drawings, forming a part of this specification, 1n which similar characters of reference indicate corresponding parts in all the 1 is a perspective view of a building-block, showing one form of my invention. Fig. 2 is a rear view f aportion of a wall constructed of these blocks. Fig. 3 is a sec- Figure tional view -on the line 3 ,3 of Fig. 2, showing the blocks slightly modified; Fig. 4 is a sectionalview on ythe line 4 4 of Fig. 2. Fig. 5 is a perspective view of another form of block embodying the principle of my invention. Fig. 6 is a view similar toAFig. 2, showing the blocks illustrated. in Fig. 5. Fig. 7 is a plan of a course of blocks of the second form, and Fig. 8 is a sectional view on the line 8 8 of Fig. 6.

Mv invention is designed especially to be ein loyed with walls formed in place by ino ding concrete or other plastic material between afwall of veneering-blocks .and a temporary backing. .Such walls are preferably yprovided upon their front surfaces with blocks having a surface ex osed on the front sidethat will be more or essjornamental or will resemble any other kind of buildingwall. Any desired kind of veneering-blocks can be used for .this purpose, and my invenv tion applied thereto.

ln its simplest 'form'the invention conirises van undercut recess formed .in each loc-k, so that the lastic material of' which the main body of e wall is composed will enter said recess and securel hold the blocks in position upon the wall. 'Fins provides vfor a most eiiicient -bond between the'mainjbody 'understood that the ofthe wall and the veneerin'g-blocks and also v allows the wall to be built and veneered with aminimum expenditure of labor. It will be the lastic material-is introduced and that the locksare arranged'in the way in which thely are-desired to appear in the finished wa The block shown in Fig. 1 may be of any desired form, but is provided on each end with a recess c, which is connected by a perforation b through the rear wall thereof with plastic material c, which constitutes the main body 'of the wall. It will be noticed that the cross-sectional area of the cavity or depression a is larger than the area of the blocks are placed on thefront of the mold' or molding-space before opening or erforation b, and consequently a T- haped ook will be rovided by the plastic material entering t `s cavity at c. Ini other words, the recess a isundercut. In

the form illustrated in the iirst four figures the perforations b are when two blocks are arranged end to end circular openings are provided; but it will be understood that any other desired shape may be employed.

In the form shown in Fig. 5 each corner of the block is provided with a recess. d, and from these recesses extend undercut portions semicircular, so that e toward the interior of the block or in any other desired direction. y Each ofthe recesses ,d is in this form a quarter `of a circle, and `when the blocks are arranged as shown in Fig.

6 they form'semicircles with each other. lf, however, the blocks "were arranged so as not to break -oints, complete circles would be formed.,` n anyj event the plastic material of the wall c enters the recesses to form locks c2 similar to the locks c.

' In building the wall the veneering-blocks are set up in the position in which it is intended to have them remain in the finished wall,I preferably breaking joints, as shown in Figs. 2 and 6. After a suiiicient number of courses are placed in this position the concrete or other plastic material is poured in behind them, and 4it-enters the recesses described., so as to'form the locks c and c2. This locking operation is therefore accomplished in the mostsirnple'aid eicient manner merely by the 'flow of the material by gravity, or if a dry-rnolding1 system is em ing ofthe mold lmateria The plastic material'hardens in place and. forms an abso-v IOO loyed by the tamplutely perfect Vioint and loclr'fto bind the vep j These air-spaces f are preferably alternately arranged with the airespace's ofthe blocks, so as"`to break joints with them, as shown in- Figv. 3,- in order `that a particle of moisture in traversing4 the wallrom any point will en'- coun-ter an afirspace. v

yHaving thus described my invention, I claim' as new and desire to secure by Letters y I. Wall having a body of plastic material, and a veneer of blocks each block having ari undercut recess on its end for receivinga4 bond integraly with the plastic material, the

recessesbeing bounded on all sides by Walls of the blocks Qwhich .abut against each other at Vtheir ends, the one of said walls adjacent to the plastic material being perforatedv to permit the admission of said bond.

2. A wall comprising a body of plastic'ma- .t'erial having vertical parallel passages therethrough, and a veneer of blocks having vertival parallel passages alternately yarranged with respectto the first-named passages,v the abutting ends of the said `blocks being recessed, and "perforated adjacent to the plas-l tie material whereby to receive a bond inte'- gral With the plastic material.

,'-. In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
