EDWARD J. GAR-HARD, 0 F RICHMOND; CALIFORNIA.
Application filed October 24, 1921. Serial No. 509,972.
To all whom it may concern:
Be it known that I, EDWARD J. GARRARD, a citizen of the United States, residing at Richmond, in the county of Contra Costa and State of California, have invented new and useful Improvements in Building Tiles, of which the following is a specification.
The present invention relates to improvements in building tile and resides in the provision of tile which may be quickly and easily laid or assembled to form walls, ce1lings, partitions, floors and other structural units.
The primary object of the invention is to provide simple, inexpensive tile construction, whereby the tiles may be cheaply and easily manufactured and readily laid or assembled in interlocked relation without employing cement or mortar, thus making possible amore expeditious building operation in the construction of walls and the like and effecting a saving in time, labor and material as compared to building operations heretofore carried out.
The invention possesses other advantages and features some of which, with the foregoing will be set forth at length in the following description where I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming a part of the present specification. In said drawings I have shown one form of the construction of my invention, but it is to be understood that I do not limit myself to such form since the invention as expressed in the claims may be embodied in a plurality of forms,
Referring to the drawing:
Figure 1 represents a horizontal sectional View of a wall constructed with tile of my invention, a special arrangement of the tiles being shown at one end of the wall.
Figure 2 is an enlarged perspective view of the tile of my invention.
Figure 3 is a top plan View of the studding and key strip with which the tile interlocks.
Figure dis a fragmentary side elevation of the studding and key strip.
Referring particularly to the accompanying drawing wherein there is exemplified one embodiment of the invention 1 designates a wall composed of my improved tile 2, the tiles being laid one upon the other with studding 3 and key strips t interposed be tween and interfitted with opposed ends of the tiles. It is thought unnecessary to illustrate the tiles as when laid one upon the other since this arrangement is common in the art.
The tile of my invention is moulded of any suitable size, preferably in rectangular form and has hollow portions 5 to reduce the weight thereof. Opposite ends of the tile, as the case may be, are of like construction, there being formed in each end a longitudinal groove 6. This groove is equidistantly spaced from opposite edges of said end and defines flanges or walls Tand 8 on opposite sides thereof. The flange or walls on one side extend outwardly from the bottom of the groove adistance less than the flange or wall 7 or in other words are shorter than the flanges 7. Thus when the tiles are laid the grooves 6 at the opposed end or side faces thereof aline with one another and like wise the flanges 7 and 8 of one tile aline with the corresponding flanges of the next tile. The flanges 7 are of such length that they are slightly spaced whereas the flanges 8 are spaced apart a greater distance.
In carrying out a building operation with the tile of my invention such as in building the outer walls 4 a house or like structure, the studding 3 and key strips 4- are first set up in properly spaced relation depending on the size of the tile. The tiles are then laid from above, one upon the other so that the key-strips 4: will extend into the grooves 6 in the opposed ends of the tiles, and the studding 3 will lie between the opposed ends of the flanges or walls 8 with the wall or flanges 7 nearly contacting as shown in the drawing. In this way a wall, ceiling or the like may be constructed in a shorter period of time than is usually required, and the use of cement or mortar and skilled labor are dispensed with. Also with my tiles it is unnecessary to use, sheathing tar paper and wire, since the spaces between the flanges 7 will provide for formation of locking bonds in plaster which may be directly applied to the outer side of the wall formed by the tile.
It will thus be seen that with special end construction of my tile and studding and key strips, a rigid strong and reliable interlocking of the tiles is eflected as well as an interlocking of the wall with the studding 3 which latter comprise major structural units of the building. The key strips 4 prevent lateral displacement of the assembled tiles and end to end arrangement of the tiles between the studding insures against longitudinal displacement.
As at one end of the wall in Figure 1 the tiles may be reversed to provide a substantially closed locking space between their ends. This space may be filled with cement or mortar to form a bond" between the tiles.
It will be noted that the studding and key strips substantially fill the grooves 6 or better the spaces between the ends of the tiles and due to this particularly as regards the key strips, the use of ta-stenings strips of metal or wood or cement along the studding at the inner faces of the tiles is unnecessary. Since the flanges 7 and 8- ,are subject to being knocked against and broken or cracked they are formed thicker than the walls proper of the hollow tile and are therefore reinforced and less apt to break or crack; This thicker formation is easy to provide for and does not in any way add to" the cost of production.
1. A building construction comprising a wall or like structure made up of a plurality of tiles, each of said tiles having like ends formed with grooves adapted to aline with the similar grooves of the next ad acent tiles, the walls of said grooves on one side being shorter than the walls on the opposite side,
formed with grooves adapted to aline with similar grooves of the next adjacent tiles, the walls of said grooves on one side being shorter than the walls on opposite sides, studding extending between the shorter walls and a single key strip extending across the inner face of the studding and projecting laterally from the sides of the stiulding, said key strips engaging in the grooves of the tiles disposed on opposite sides of the studding and substantially filling the spaces provided by said grooves so as to prevent lateral displacement of the tiles.
