An improved construction brick, which is self-aligning and may be fastened in place without mortar. The top of each brick is formed with a series of pointed projections which mate with matching indentations in the bottom surface of the supported brick, when the bricks are stacked and arranged in the conventional overlapping pattern of construction bricks. Similar interlocking projections and recesses are located on the inner side surfaces of the bricks. Through interior vents are located in the interior of the bricks, with vent passages running from the top to the bottom brick surfaces, and with passageways for utilities.

The top of each brick is formed with a series of pointed projections which mate with matching indentations in the bottom surface of the supported brick, when the bricks are stacked and arranged in the conventional overlapping pattern of construction bricks.

coNsTRUcnoN BRICK SUMMARY OF THE INVENTION This invention relates to an improved construction brick, and particularly to a construction brick which is self-aligning.
The construction brick of this invention may be employed without the use of mortar to build firm walls and building exteriors, with a stack of bricks being held in place by the alignment of pointed projections lying on the upper surface of each brick mating with matching indentations on the lower surface of the bricks directly above, with the pattern of indentations and projections fitting together when the bricks are laid in the conventional overlapping pattern customarily employed. Interior side surfaces are also formed with matching projection and indentations, and the bricks are fitted with through vertical passages from the upper to the lower surfaces for venting purposes.
BRIEF DESCRIPTION OF THE DRAWING The objects and features of the invention may be understood with reference to the following detailed description of an illustrative embodiment of the invention, taken together with the accompanying drawing in which:
FIG. 1 is a perspective view of the brick;
FIG. 2 is a perspective view of the brick from the opposite end;
FIG. 3 is a side view of the brick;
FIG. 4 is a plan view of the brick;
FIG. 5 is an end view of the brick;
FIG. 6 is a side view of a half block brick;
FIG. 7 is a perspective view of an adaptor brick;
FIG. 8 is an end view of an adaptor brick; and
FIG. 9 is a side view of an adaptor block.
DESCRIPTION OF THE PREFERRED EMBODIMENT:
Turning now descriptively to the drawing, in which similar reference characters denote similar elements throughout the several views, FIG. 1 illustrates brick 10 with side faces 1 l and 12, end faces 13 and 14, and top face 15. FIG. 2 illustrates the same brick 10 from the position of end face 13 and side face 12, with end face 13 consisting of male projections which mate with the female recesses of end face 14 of a similar brick 10. As shown in FIG. 1-6, the recesses of bottom face 16 mate with the projections of top face of a similar brick so that a series of bricks 10 of such design may be fitted together to form a conventional interlocked brick wall of a structure without the requirement of additional mortar or cement.
The interior of the brick 10 may be hollow, with vent holes 26 on the faces of the brick permitting the flow of air from the interior of one brick to the interior of adjoining bricks. Locking projections 25 may be mounted on the face of the brick with said projections 25 having projecting locking wings 22 with curved undercut sides so as to fit into mating curved recesses 27 of adjoining bricks.
Through holes 21 may be formed in the interior of the bricks for the passage of electrical wires. weakened face sections 31 in the sides of the brick may be opened at will to provide access to such through holes when it is desired to create such utility passageways through the sides of the brick or adjacent bricks.
The sides of each brick are finished along the side edges, either as projections 28 or as mating recesses 29 for the alignment of adjacent bricks which are lying top-to-bottom or end-to-end.
A half-brick, as shown in FIG. 6 is used to terminate the end of a line of bricks so as to form a smooth, flush end surface.
FIGS. 7-9 illustrate the shape of an adaptor brick 35 which may be employed to join with mortar a conventional brick to the bricks 10 of this invention. Brick 35 is formed with a central vertical recess 36 in one end wall 34 which mates with the projections 25 of an end face of brick 10. One horizontal central recess 37 along the bottom face 39 of adaptor brick 35 mates with projections 25 of a top face of a brick 10, with the other faces of adaptor brick 35 being formed of a flush configuration.
Since obvious changes may be made in the specific embodiment of the invention described herein, it is indicated that all matter contained herein is intended as illustrative and not as limiting in scope.
Having thus described my invention, what I claim as new and desire to secure by letters Patent of the United States is:
1. An improved construction brick which is selfaligning and may be fastened in interlocking fashion to adjoining such bricks without the use of mortar or other adhesives,
said brick containing projections of the side faces along one vertical end face and one horizontal face for alignment purposes, said :brick being formed with matching recesses on the opposite vertical end face and horizontal face for the purpose of mating with the projections on the side faces of adjacent similar bricks, with a rib structure which projects from one vertical brick face and one horizontal brick face that matches the recess on the opposite vertical brick face and opposite brick horizontal faces so that the projections on one brick face may mate with the recesses on the face of a similar adjacent brick, with said rib structure formed with wings of essentially wider rib sections, said wings having curved, undercut sides which mate with the curved undercut sides of the recesses in the opposite faces of similar shaped bricks.
2. The combination as recited in claim 1 in which the interior of the brick is hollow, with vent holes in the face of said brick providing for the circulation of air from the interior of said brick to the interior of an adjacent brick.
3. The combination as recited in claim 2 in which said brick contains a through passageway for the insertion of a utility pipe or wire, with a side of said passageway being formed with a weakened section which is readily knocked out when it is desired to connect to said passageway, through the side of the brick.
