Application February 4, 1935, Serial No. 4,964
This invention relates to building blocks, and has for its object the provision of wooden blocks which may be laid in the same manner as bricks 'or building blocks of other material and which will produce a strong, durable wall readily lending itself to any scheme of ornamentation. It is also an object of the invention to provide building blocks to which plaster may be applied on the inside of a wall composed of the blocks and which may receive stucco or other finish upon the outer sides. The invention is illustrated in the accompanying drawing, and consists in certain novel features which will be first fully described and then more particularly defined in the appended claim.
In the drawing:
Figure 1 is a perspective view of a portion of a wall constructed of blocks embodying the invention.
Figure 2 is a transverse section of a portion of such a wall showing a slight modification.
Figure 3 is a transverse section showing another variation.
The blocks, shown at I, may be of any desired dimensions and may conveniently be of the dimensions of ordinary building bricks. The blocks are to be laid in courses to break joint, as indicated at 2, and, to resist endwise separation of adjacent blocks in any one course, splices 3 are inserted through the blocks at the joints so as to secure the blocks together. The blocks are provided with top walls, or tops, H3 and inner edges H6. On the top walls of the blocks are central ribs 4 and at their front edges are similar ribs 5 and in the under sides of the blocks are grooves, indicated at 6, in positions corresponding to the locations of the respective ribs, as clearly shown in Figure 1, so that the ribs on one block will engage in the grooves in a superimposed block and thereby maintain the blo'cks in the proper relation in the wall. On their inner edges IIB, the blocks are somewhat reduced so that a space 1 will be left between any one block and the bottom of a superimposed block at the inner edges ofthe blocks, and adjacent this reduced portion each block has a longitudinal groove 8 formed therein so that at the outer side of the groove will be a rib 9. An L- shaped recess is thus produced extending longitudinally of the wall between successive courses of the blocks and plaster may be applied to the blocks and will be keyed thereto in the recesses. as will be understood. The outer edges of the blocks may be given any desired configuration and in Figure 1 they are inclined inwardly and upwardly so that the completed Wall has the appearance vof ordinary weather boarding.
The wall thus produced will be very firm and strong and need not have any adhesive or mortar interposed between successive courses, although such material may be interposed if desired. The splices 3 may be driven through the meeting ends of adjacent blocks in one course into the upper portions of blocks in a lower course, as shown in Figure 1, so that the several courses will be positively bound together. The outer surfaces ofk the blocks4 may be painted or otherwise treated and may be coated with stucco or other finish. In Figure 3 the louter edges of the blocks are convex vertically, as shown at ID, so that the completed wall will have the appearance of having been built from logs. The blocks shown in Figure 3 have ribs II on their, upper sides engageable in grooves I2 in the bottoms of superposed blocks, as shown, but the ribs and grooves are not located identically with the ribs and grooves shown in Figure 1. In the wall shown in Figure 3, also the plaster-receiving grooves or recesses have been omitted.
In Figure 2, the blocks I3 have the same contour as the blocks shown in Figure 1 at their edges, but the rear or inner ribs I4 are disposed immediately adjacent the plaster-receiving grooves, and the grooves I5 in the bottoms of the blocks are correspondingly located. Deep grooves I6 are formed in the blocks I3 longitudinally thereof and extend upwardly from their lower surfaces near their front edges and downwardly from their upper surfaces near their rear edges. When the blocks are superimposed in a wall these deep grooves will form dead air spaces which will increase the sound-proof and waterproof qualities of the completed wall. In all forms of the invention, the blocks are simple in construction, easily handled and a wall formed therefrom may be cheaply and rapidly built.
Having thus described the invention, what is claimed as new is:
A wall composed of wooden building blocks arranged in superimposed courses, the blocks having their under faces formed with front and rear longitudinally extending grooves and their upper faces formed with front and rear longitudinally extending ribs for engagement in grooves of superimposed blocks, the front grooves being spaced from the front edges ofthe under 'faces of the blocks and the front faces of the blocks extending upwardly at a rearward incline and merging into front faces of the front ribs whereby the lower portion of each course projects fortongue near its rex' edge adapted to project into a mating groove in the vblock mounted thereabove i'or providing e rear anchor for the blocks.' each ot said blocks having a groove adJacent said upwrdly projecting tongues and having a lo. relatively short rim opposite said tongues to define an open space between the bottom inner edge Aot an overlying block and the upper edge of the rib to cooperste with the groove formedv between the rib and the upwardly projecting ltongue to denne an inverted L-shaped lockingspace for plaster. the inner vertical mri'aoe ofsaid blocks being in the slime` vertical plane.
