BUILDING-BLOCK.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed March 2, 1905. Serial No. 248,079-

To all whom it may concern:

Be it known that I, JOHN S. CULLEY, a citizen of the United States, residing at Louisville, Jefferson county, State of Kentucky, have invented certain new and useful Improvements in Building-Blocks, of which the following is a specification. v

The present invention relates to an improvement in building-blocks and walls constructed therefrom.

The object of the invention is to provide a building-block by means of which a strong and durable wall of minimum thickness will be provided with interior passages or chambers adapted for use in ventilation or to serve as conduits for any desired purpose.

In the accompanying drawings, Figure 1 is' a perspective view of a sectionof wall constructed in accordance with this invention. Figs. 2 and 3 are detail views of blocks employed in the construction of wall illustrated in Fig. 1. Fig. 4 is a plan of a wall constructed in accordance with the invention and differing slightly from the form illustrated in Fig. 1. Fig. 5 is a detail view of one of the blocks employed in building the wall shownin Fig. 4:. Referring to the drawings, it will be seen that each of the blocks, which may be made of any suitable material, consists of a body of substantially uniform thickness except at one end, where it is provided with a lateral projection or enlargement, which serves when the blocks are assembled to connect adjacent blocks and cause the same to be interlocked to form a solid wall. It will be noticed that each of said projections 1 extends longitudinally of the block for less than one-half the length of such block and has a face or side 2 that forms an acute angle with the face or side of the body 3 of the block from which said projection extends. Preferably the parts are in the proportions illustrated, the height of the block being one-third (t) of the length thereof and the thickness of the body 3 being one-half of the height. The projection 1 preferably projects beyond the body of the block a distance equal to the thickness of such body.

Referring to Fig. 1, it will be seen that when the blocks are assembled and the projections 1 thereon interlocked a plurality of passages or chambers 5 will be formed within the wall, which passages will be separated by a solid body of masonry equal in thickness to the longest diameter of said passages. In

at an angle to the body 3.

case it is desired that the wall have an angular formation it is desirable to employ special corner-blocks, such as are illustrated in detail in Fig. 3. Each of such blocks has a projection 1 at one end and differs from the common stretcher-block shown in Fig. 2 only in having its body bent at the end opposite such projection 1 to form a member 6 extending Such section 6 is of the same dimensions and forms a continuation of the body-of the block.

Referring to Fig. 1, it will be seen that by means of the stretcher-blocks illustrated in detail in Fig. 2 a strong and durable wall can be readily constructed, the several blocks being interlocked, so as to provide a very durable structure. tend at an angle to the adjoining section, corner-blocks such as are shown in Fig. 3 or having a section 6 extending at any desired angle to the main body 3 may be employed in connection with the stretcher-blocks as shown in Fig. 1. It will be observed that it is notnecessary to make the wall of undesirable thickness in order to obtain passages 5 of such dimensions that they are adapted to receive flues for heating or to serve as conduits for wires, &c. the form and of the dimensions illustrated and described the blocks are securely interlocked and solid pillars or partitions are formed between the several passages 5, which passages are completely surrounded by the blocks.

In Fig. i is illustrated a slightly-modified form of the invention, according to which while the thickness of the wall is slightly increased the number of passages 5 is doubled with'out sacrificing any of the strength of the structure. In this form of the invention in addition to such stretcher and corner blocks as are shown in Figs. 1 and 3, for example,

use is also made of a partition-block consisting of a body 7, corresponding to the body 3 of the stretcher-block 5. Such partition-block is provided at one end with oppositely-extended projections 8, each corresponding in form and proportion to the projection 1 of the stretcher and corner blocks before described that is, each of said projections 8 is provided with a face forming an acute angle with the face of the body of the.block from which it projects.

cordance with the invention illustrated in Fig. 4 the projections 1 of the stretcher-blocks are interlocked with the projections 8 of the par- If one section of the wall is to ex-- By making the projections 1 in In building a wall in ac- IIO tition-block, the wall thus produced having a thickness equal to that of three courses of the blocks, whereas the wall shown in Fig. 1 is but two courses thick. In the wall illustrated in Fig. 4, however, the number of passages 5 is double that of those in the wall shownin Fig. 1, such.passages being arranged on opposite sides of the bodies of the partitionblocks 7.

One of the advantages of the present invention is that by it it is possible to construct a wall having a number of air chambers or passages, which is very desirable, without weakening the individual blocks by forming openings or passages therein. Again, as stated above, it is possible by this invention to provide a Wall of minimum thickness with condui ts or passages for fines or pipes each of which is completely surrounded by the solid blocks. By the invention also the blocks are self-binding when laid in a wall or tier, and therefore the necessity for using iron or wall ties or separate binding-blocks is avoided.

As before stated, the blocks may be made of any suitable material, and the outer faces thereof may be ornamented in any desired manner.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is

1. A building-block having at one end an integral lateral projection which extends longitudinally of the block for less than half the uniform thickness except for said projections thereon.

4. A building-block consisting of a body having at one end oppositely-extending projections, a face of each of said projections forming an acute angle with the face of the body of the block from which said projection extends and the body of the block being of substantially uniform thickness from said projections to the opposite end thereof.

5. A wall composed of a series of buildingblocks each having a lateral projection at one end, which extends longitudinally of the block for less than half the length thereof, and the block being of substantially uniform thickness except for said projection, the said projections of adjacent blocks engaging each other, whereby the blocks are interlocked, the smaller end of one or both members of each pair of interlocked blocks extending longitudinally beyond the projection of the other block of said pair to form a plurality of interior passages or chambers in the wall.

6. A wall composed of a series of buildingblocks arranged end to end and each having at one end oppositely-extending projections 8, one face of each'of said projections forming an acute angle with the face of the body of the block from which said projection extends, and two series of blocks arranged on opposite sides of the first said blocks, and each having at one end a lateral projection, one face of which is adapted to engage the inclined face of the adjacent projection of one of the first said blocks, whereby said series of blocks are interlocked, the bodies of said blocks constituting sides of a plurality of interior passages arranged on opposite sides of the bodies of the first said blocks.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN S. CULLEY.
