BUILDING BLOCK AND WALL.

SPECIFICATION forming part of Letters Patent No. 743,391, dated November 3, 1903. Application filed May 29,1903. Serial No. 159,357. (No model.)

To all whom it may concern:

Be it known that I, FRANK E. KIDDER, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Building-Blocks and WValls; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which forni a part of this specification.

My invention relates to'improvements in building-blocks and walls, my object being to provide a block which when laid in a wall shall form a construction which shall be exceedingly durable and possess the maximum efficiency in a construction of this class; and to this end the invention consists of the features hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a perspective view in detail of one form of my improved building-block. Fig. 2 is a similar view showing a number of these blocks laid in a wall, all the structure except the uppermost block being shown in thelower or one of the single courses. Figs. 3, 4, and 5 are top views in detail, illustrating a number of blocks assembled, the blocks being of a slightly-modified form of construction as compared with the construction shown in Fig. 1.

The same referencecharacters indicate the same parts in all the views.

Referring first to Figs. 1 and 2, let the numeral 5 designate my improved buildingblock, whose body portion 5 is provided with a central projection 5, notched at its top and bottom, as shown at 5. The extremities of this block are reduced, as shown at 5 From the inner face of the wall to the recess 5 the block is curved in this form of construction, as shown at 5 while the face of the projec tion 5 is fiat or lies in a single plane. WVhen this block is laid in a wall, the blocks are arranged end to end and are supposed to be two blocks in thickness, as shown in Fig. 2 of the drawings. These blocks are so arranged that they break joints vertically-that is to say, the double recess formed by the two recesses 5 where the two blocks are brought end to end is of a suitable width to receive the face or outer edge of the projection 5 of the block on the opposite side of the wall 6, breaking the vertical joints. This will be clearly understood by reference to Fig. 2. By forming the recesses 5 the construction is made practicable, whereby the maximum length of the projection 5 may be employed, thus giving the wall the greatest possible binding or hold ing efficiency, so far as uniting the blocks together in-the completed wall is concerned.

The forms of construction shown in Figs. 3, 4, and 5 vary only in details from the construction shown in Figs. 1 and 2, already described. Hence the body of the block in each case will be designated 5, the same as in the principal views. In the form of, construction shown in Fig. 3 the extremities of the block are provided with curved recesses 5 which when two blocks are put together end to end form a semicircular recess adapted to receive the counterpart or rounded face 5 of the projection 5. I

In the construction shown in Fig. 4 the projection 5 is substantially the same as that shown in Fig. 1, but the recesses in the extremities of the block, which are designated 5 are right angular in shape instead of being curved on one side, as shown in Figs. 1 and 2. The two recesses 5 when the blocks are brought end to end form a double recess for the reception of a fiat face of the projection 5, the same as in Figs. 1 and 2. In the construction shown in Fig. 5 the face of the projection 5 is pointed, as shown at 5, being formed by two bevels which-form an angle of approximately forty-five degrees wi th the outer flat face of the block, while the extremities of this form of block are beveled, as shown at 5, so that when two of the blocks are brought end to end a V- shaped recess is formed which is the counterpart of the bevel or pointed face of the projection 5 which pointed face or V- shaped recess is adapted to receive.

From the foregoing description the use of my improved building -block to form walls will be readily understood, particularly by reference to Figs. 2 to 5, inclusive.

Having thus described my invention, What I claim is,

1. A building-block comprising a body part, and a central projection Whose outer face is curved or rounded, and Whose extremities are curved so that When the blocks are arranged end to end on opposite sides of a Wall, the curved end recesses of tWo blocks form a semicircular recess adapted to receive the curved face of the projection of the corresponding block on the opposite side of the Wall.

2. A Wall composed of building-blocks consisting of vertical courses arranged one above another, each block having a central projection and end recesses the blocks of any course being arranged end to end in such a manner as to break vertical joints on opposite sides of the wall, the projections of the blocks of the different vertical courses being alternately arranged in such a manner that the central projections of the blocks on opposite sides of the Wall occupying a position immediately above and below each other, coincide as to position but extend in opposite directions.

In testimony whereof I affix my signature in presence of two Witnesses.

FRANK E. KIDDER.
