JAMES HUNDLEY, or NOBLESVILLE, 111mm.

INTER-LOCKING BUILDING Enron.

Application filed September 22, 1921. Serial No. 502,477. I

T all whom it may concern:

Be it known that 1, JAMES 'HUNDLEY, a citizen of the United States, and a resident of ill the city of Noblesv-ille, county of Hamilton, and State of Indiana, have invented new and useful Improvements in Interlocking Building Brick, of which the following is a before the concrete is poured into the Wall moulds or forms, and which will be cemented together and be bound and tied integrally to the wall as the concrete is poured. A further object is to provide a brick which interlocks longitudinally with its adjacent bricks as it is being laid in the wall, and which is provided with lateral abutments forming exteriorly closed apertures between adjacent bricks into which the concrete mayflow as the wall is being poured. A still further object is to provide a brick with a plurality of depending transverse lugs at its extremities, a transverse depression medially of its length on the opposite face fro-n1 said lugs, a longitudinal depending lug connecting said transverse lugs, a vertical tongue on one longitudinal extremity of said brick, and corresponding recesses to receive said tongue and said longitudinal lug, to form apertures between adjacent bricks when they are laid together to form a wall.

With these and other objects in view, my invention will be best understood by reference to the accompanying drawings, in which Figure 1 represents an exterior elevation of a fragment of a Wall formed of these bricks. Fig. 2 is a vertical transverse section taken on line 22 of Fig. 1; Fig. 3 is a plan view of the same, and Fig. 4 is an interior side elevation of the same wall. Fig. 5 is a top view of one of these bricks; Fig. 6 is a bottom view of one of the bricks; Fig. 7 is a sectional view on line 77 of Fig. 5; Fig. 8 is a rear side elevation of one of the bricks, and Fig. 9 is a front side elevation of same. Fig. 10 is a'perspective view of one of said brick.

In the drawings, which illustrate a preferred form of the device, and in which like numerals refer to like parts throughout, the numeral 1 indicates the brick in general, 3 being its top face, its bottom face,'and 2 its outeriface. vertical side wallsYo' is formed'medially of face '3, and a transverse depending lug 7 with a vertical faceS is formed at ea'cheX- treinity of face 41 Joining the lugs 7'is a longitudinal depending lug 9' having a A transverse recess 5"'With.

vertical face 10, while a recess 11 aligning with lug 9 is formed on the opposite edge of the brick, the depth 12 of said recess. being ess than the length 10 of lug '9. A vertical lug13 is formed adjacent one exterior'corner of the brick and a corresponding recess 16 is formed inthe opposite exterior corner, i

the length '14 of lug 13 being greater than the depth 15 of recess 16. A plurality of vertical recesses 17 may be formed on'the inner face of said brick and these recesses may be dovetailed as at "18 if desired, to strengthen the bonding between the bricks 1 and the concrete Wall 21.

lVhen these brick are laid together to 11, and the tongue 13 will enter the recess 16,

The length 8 of lugs 7 and length. 10 of lug 9 being greater respectively than the depth 6 of recess 5 and depth 12 of recess 11, it is apparent that an inclos'ed aperture 20 will be formed horizontally between adjacent brick, and the tongue 13 being of greater length 14 thanthe depth 15 of recess. 16, an. aperture 19 communicating with aperture 20 will be formed between the ends of adj acent brick; When viewed eXteriorly, the wall would appear to be made of bricks without intervening mortar, but should it be desired to convey the impression of having mortar between the bricks it is evident that the longitudinal lug .9 and the vertical tongue 13 may be formed, while in the mold in which the bricks are pressed, of a ma teria: having a different consistency or color,

to convey such impression, as is. indicated by the numerals 23 and 22 respectively. In practice it may be found advisable to apply a thin coating or wash of cement to the contacting surfaces of the abutting lugs and re- I claim as new and desire to protect by these Letters Patent is 1. A building brick formed with a plurality of depending iugs'in spaced relation to one another on one horizontal face of said brick, a vertical lug adjacent one end of said brick adjacent the exterior face of the brick, a vertical recess on the opposite end of said brick in alignment with said vertical lug, a transverse recess in the surface opposite said depending lugs and in spaced parallel relation to said depending lugs, aplurality of bonding recesses on the interior face of they brick,said vertical lug projecting to a greater extentthan the depth of said vertical recess, and said depending lugs projecting to a greater extent than the depth of the transverse recess, a longitudinal depending lug in alignment with said vertical lug and connecting one extremity of said first mentioned depending lugs adjacent the exterior face of the brick, a longitudinal recess on the opposite edge of said exterior face so positioned that when a series of said brick are laid together to form a wall the exterior face of said wall will form a continuous smooth surface while the interior face will possess spaced recesses between adjacent bricks,-except where said lugs engage said recesses, essentially as and for the purpose described.

2. A building brick formed with a vertical lug adjacent one end, a depending horizontal lug 1n the same plane as said vertical lug, a vertical recess on the opposite end of said brick from said vertical lug, a horizontal recess on the opposite edge of said brick from said horizontal lug, a depending transverse lug on each end of said brick, a transverse recess medially placed on the opposite side of said brick from said transverse lugs, all of said. lugs being of greater length than the depth of said recesses, so that when aid bricks are laid together to form a wall, said lugs will register with said said brick, a vertical lug adjacent one end,

and a dependinglongitudinal lug in the same vertical plane as the vertical lug, a vertical; recess at the opposite end from said vertical lug, a horizontal recess opposite said horizontal depending lug, a transverse recess on the upper surface olsaid brick, said vertical lug and said horizontal depending lug being formed of a different material from the remainder of aid brick, said vertical lug being of greater horizontal length than the horizontal depth of said vertical recess, said horizontal and said transverse depending lugs being of greater vertical length than the depth of said horizontal and said transverse recesses, so that when a series of said brick are laid up to form a wall, said wall will have an essentially continuous exterior surface, and a series of recesses will be provided between adjacent bricks, so that plastic and semi-fluid material may enter said last mentioned recesses to bond and tie said series of brick to an adjacent wall or structure.

In witness whereof I hereunto set my hand in the presence of two subscribing witnesses.
