UNITED STATES PATENT OFFICE.

HENRI CHOQUET AND ALBERT DESPATURE-COUSIN, OF PREMESQUES,

' FRANCE.

INTERLOCKING BRICKS.

SPECIFICATION forming part of Letters Patent No. 716,865, dated December 30, 1902.

Application filed May 14, 1902.

To all whom it inc/y 60721067771.

Be it known that we, HENRI and ALBERT DESPATURE-COUSIN, citizens of the French Republic, and residents of Prem'esques, Nerd, France, have invented certain out the use of mortar, if desired, or otherwise.

strengthening brick walls, so enabling the latter to be'made thinner than usual, and thereby economizing space, labor, and material. In this manner temporary buildings may be quickly established by the use of this improved brick locking arrangement, and both the bricks and the keys for the same can be made beforehand and of the same material, or the keys may be formed of other appropriate solid material. 7 r

In the accompanying drawings, Figures 1, 2, 3, 4, 5, 6, S, 10, 11, and 12 are plan views of different form set bricksincluded in theinvention. Fig. 7 is a plan view of the locking-key, and Figs. 19 and 20 are perspectives thereof. Figs. 13, 14, 15, 17, and 18 are perspectives of difierent forms of bricks. Fig. 21 is a side elevation of a wall constructed in accordance with our invention. 25, 16 and 9 are respectively plans of consecutive courses of various forms of walls embodying the invention.

Although the bricks and their locking means are separate parts, they may be ap propriately referred to as and are hereinafter called keyed bricks in the same manner as one speaks of key-locks.

The brick and its key may be made of any suitable, material to suit any particular re quirements.

The brick, which may vary in shape and dimensions for various purposes, is formed with one or more slots or openings a, provided either at one side or several sides or at portion 1), as illustrated in the annexed draw- Cnooun'r.

ings. The locking device or key for securing the bricks is provided with corresponding heads or flanges c. The web portion d of the key, which joins the two heads, may be varied in width, so as to suit the parts which it serves to lock together or the distance between rows of bricks when hollow double walls are constructed with an air-space be tween the bricks. The two parts-namely, the bricks and the keyswhen properly arranged provide a very strong assemblage which, together with the mortar and after the drying of the latter, forms into a solid block or monolith. It will be easy to realize the progress and superiority of this improved arrangement over existing method of brick construction by considering that this process comprises all the advantages of the ancient methods, in which the cross-joints of the brick walls have always been the chief feature to insure the strength-of building construction.

In addition to the aforementioned advantagesthe invention provides, furthermore,

pools, settling-tanks, reservoirs, wells, the

prooffloors,and generally wheneverbrickscan be employed. It will also be found very useful in the construction'of drying-rooms and ventilation-cham hers by forming the bricks with holes of any convenient section -for example, square, as shown in the accompanying drawingswhich hollow bricks form an additional protection against the cold air. It is, however, to be distinctly understood that the said holes may be omitted without prejudice to this invention and that, moreover, the lockingkeys need not be prepared beforehand, as they may be formed subsequently by running thin mortar or cement into the bricks after being built up.- I The mortar may be strengthened by the introduction of pieces of iron bars or rods, which become fixed in the mortar, and thus constitute a very reliable assemblage.

By using alternately a layer of bricks as shown in Fig. 8 and a layer of bricks of the form shown in' Fig. 1 the vertical cross-joint is obtained. By repeating this arrangement for each two superposed layers the continuity of the cross-joints is carried out, as shown in Fig. 21, which shows an elevation of a wall constructed in this manner, whereby the interlocking keys, Fig. 19, as indicated in dotted lines, always engage in two superposed layers. This is an important feature, which can be carried out without difiiculty by starting the first layer with short keys, like those shown in Fig.20.

Having now fully described our invention,

what we claim, and desire to secure by Letters Patent, is-
