To all whom it may concern:

Be it own that I, SAMUEL So oMnN Law, a citizen of the United States, and resident of Mattapan, county of Sufiolk,

5 State of Massachusetts, have invented an provement in Building Construction, of which the following description, in connec tion with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to building construction and particularly to building construction involving the use of blocks of cement or cementitious material. The object of the invention is to provide a building block oi novel term which can be readily laid up in the form of a wall and which is constructed so that when the blocks are thus laid up they can be readily secured together to sim ly by the insertion of cement or motar in a igned grooves in adjacent blocks.

' lln order to give an understanding of my invention I have illustratedin the drawings some selected embodiments thereof which will now be described after which the novel features will be pointed out in the appended claims.

1F ig. 1 is a perspective view of the corner of a wall formed of building blocks embodyingr my invention.

ig. 2 is a front view of a portion of a wall.

Fig. 3 is an end view of Fig. 2.

My improved building blocks are indicated at 7, in Fig. 1. Each block is made of cement or some suitable cementitious substance and may have any desired shape or size. Each block is formed on both its top lace and its bottom face with a groove in ich is aligned with a corresponding groove in the block beneath or directly above when the wall is laid up. These grooves are shown at 2 in Fig. 1, and each groove extends only partially across the block, said groove terminating at a point near the front face of the block but not extending clear to the front face. These grooves 1 and 2 will preferably be dovetailed in shape and I will also preferably employ two grooves in each face, said grooves being so situated relative to each other that the distance between the grooves on any face is twice the distance between each groove and the end of the block. at ere this arrangement of grooves extill dll

lib

lets the blocks may be placed one on the other so that they will break. joints as shown in Figs. 1 and 2 and in each case the grooves on the bottom of any block will come into alignment with the grooves on the top of the block beneath. After the building blocks have been laid up one on the other to form the wall then motar or some other suitable cementor binding material 4: is inserted into the aligned grooves as shown in Fig. 1. When the mortar tar or cement t sets the blocks will be firmly locked together thus making a rigid wall structure.

ll may, if desired, form each block with a rabbet 3 along either its top or its bottom edge at the front thereof. This rabbet may extend along the top edge merely or may also be formed along one of the vertical edges. Where this rabbeted structure is employed 75 it is my intention to fillthe grooves formed by the rabbets with cement or motar 5, after the blocks are laid this giving the com pleted Wall the appearance shown in Fig. 2.

In Fig. 1, 6 indicates a foundation on so which the wall is laid.

ere the wall is built by laying the blocks so that they break joints it Wlll be necessary to employ a block of one-half length as shown at 17 in some places. Thistt one-half length block however will have the grooves 1 or 2 therein properly situated to come into alignment with the grooves in ph ii full length blocks when the latter are One advantage of my invention is that a wall can be built up by simply placing the blocks on each other and without the necessity of providing a bed of mortar or cement for each block as it is laid. Since the blocks are all made perfectly true a wall can be built up perpendicularly by unskilled labor and after the blocks are laid up the grooves can be filled with cement or mortar.

I claim:

1. A building block of cement having on both the top and bottom faces two dovetail grooves extending transversely from the inner face part way'only to the outer face, said grooves being placed so that the distance between the grooves on any face is twice that between each groove and the end of the block, whereby when the blocks arelaid up in a wall with the blocks in adjacent courses breaking joint the two grooves 110 hit ltd

Mid

the top face of any block in one course are in alignment with the grooves in the meetin ends of two blocks in the course above,

all of the grooves being open at the inner 5 face of the block so that the blocks may be laid up (11' and subsequently mortar or cement may be forced into the aligned grooves to bond the blocks together.

2. A wall formed of a plurality of build- 10 ing blocks laid one on the other with the blocks on adjacent courses breaking joint,

each block having on both the top and bottom faces two dove-tail grooves which are so situated that the distance between the 15 grooves is twice the distance between each .aligned grooves and tying the blocks to- 25 gether.

In testimony whereof,I have signed my name to this specification.

SAMUEL SOLOMEN LEVY.
