JEL3LQW TILE BUILDING BLOCK.

Application filed April 12,

- and declare the following to be a full, clear,

and exact description oi the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying draw- .g

in s, which form a part of this specification.

@ly invention relates to a hollow tile building element or block, shown in the accompanying drawings and more particularly described in the following specification and claims.

The primary object of thisinvention is to provide a building block which may be constructed of any suitable plastic material but which is preferably formed of clay that it maymore closely represent brick which the outer face of the block is grooved to repremnt.

A further object of this invention is to provide a building element with an interlocking joint at each end of the block adapted to co-operate with similar blocks, whereby it may present the appearance of a brick wall of usual construction.

A further object of the invention is to provide for retouching all exterior mortar joints of the block, either real or imitation, so as to give the'appearance of a brick wall 7 of usual construction.

A further object of the invention is to provide a building element representing the equivalent of a plurality of bricks with an integral hollow tilebaeking, thereby greatly reducing the cost of material and labor involved over a wall or" like character formed of separate brick units of usual construction.

Another object of the invention is to provide a building element having an interlocking or dove-tailed joint with a slightly arc-shaped surface that it may be rapidly formed by a rotary cutting knife in the manufacture of the block.

A further object is to provide a building 1922. Serial in. 551,805.

'element with interlocking crenelated portions having a relatively broad base adjacent the body of the block converging to a blunt outer edge to provide for maximum strength with a minimum mortar surface.

A further object of the invention is to provide a block having a minimum articulating surface, thereby reducing the amount of mortar required for the joints, and the labor necessary for fitting the blocks toether.

A further object of the invention is to provide the ends of the blocks with a plurality of vertically disposed opposing grooves for receiving liquid or plastic mortar, the purpose being to break joints between. the blocks, and to secure them in place, the construction being such that the grooves in the blocks register with the partition walls in the blocks beneath, thereby forming a floor to receive the mortar poured into the grooves of the superimposed blocks.

With the foregoing and other objects in view which will appear as the description proceeds, the invention further resides in the combination and details of construction hereinafter described and claimed it being understood that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same.

Figure 2 is a fragmentary perspective view showing the rear of the wall which may be grooved to represent a brick face for use in constructing basement walls, garages, or wherever it may be desired to have an inner surface of finished brick.

Figure 3 is a perspective view of one of the building elements.

buil ing a wall.

Figure 5 is a fragmentary end view of the block showing the interlocking joint and one of the vertical rooves at the end of the building element fil ed with mortar.

Referring now to the letters of reference placed upon the drawings:

A, denotes a building block preferably formed of tile, it may however be made of any plastic material adapted for the pur-' pose. l3, indicates grooves in the face of the block of a character to represent-a pluralit of bricks as ordinarily arranged in C, are interlocking projecting portions spaced apart and relatively broad adjacent the body of the block and tapering toward a blunt outer end. The interlocking portions C are ada ted to articulate with correspondingily ormed recesses D in the adj aoent bloc In the embodiment shown in the drawings the crenelated ends of the block are preferably arc-shaped at the back of the projecting portions as this form lends itself to their rapid formation by a suitable rotary cutter. It owever will. be obvious that the rear faces of the interlocking portions of the block may be flat if preferred. f

E, denotes a pluralit of vertical grooves in the ends of the bloc adapted to register withthe grooves in the ad acent block to form a channel to receiveliquid mortar or cement. The grooves E are so spaced that they are adapted to register with the partition walls A in the block beneath which thus serves as a floor for the mortar poured into the grooves in the su erimposed blocks. F, denotes mortar lodged in the grooves outlining the bricks that the block may more perfectly present the appearance of an ordinarily constructed brick wall.

- In erecting the wall mortar may be spread upon the ed es and face of the interlocking portlons an also upon the edges of the partition walls of the-hollow block. Attention is especially directed to the fact that a rela tively small amount of mortar is re uired to efi'ect a suitable bond between the uilding elements, while the peculiar form of the interlocking ends in conjunction with the mortar filled vertical grooves provides a joint through which air cannot readily penetrate.-

Having thus described my invention what I claim is:

1. In a building element of the character described. a hollow block grooved upon its outer face to represent a plurality of superimposed bricks with a plurality of interlocking projecting. portions extending from the end of each block adjacent to its outer face said rojectin portions having a relatlvely widg' basef-a jacent the block and tapairing in a blunt outer end said projecting with recesses 1n the ortions alternatin ody of the block s aped to receive like ines es described, a hollow block scored upon its outer face to represent a plurality of superimposed bricks with a plurality of interlocking arc-shaped projecting portions extending from each end of the block adjacent to its outer face and alternating with recesses adapted to receive the interlocking arc-shaped projecting portions. of a similar block placed in adjacent relation.

3. In a building element of the character described, a hollow block scored upon its outer face to represent a plurality of superimposed blocks with a plurality of tapering interlocking projecting portions extending from each end of the block adjacent to its outer face and alternating with a plurality of recesses adapted to co-ordinate with like tapering projecting portions of a similarblock placed in adjacent relation and a plurality of vertical grooves formed in the ends of the block between the tapering pro'ecting interlocking portions and the rear. ace of the block. i a

4. In a building element of thecharacter described, a hollow block rooved-fupon its outer face to represent a p urality of en erimposed bricks with a plurality of we geshaped interlocking projecting portions extending from each end of the block adjacent its outer face and alternating with recesses in the body of the block adapted to receive the projecting interlocking portions of a similar block placed in adjacent relation and a filling of mortar or cement lodged in the face grooves of the blockwhereby said block may more closely resemble a wall formed of a plurality of separate bricks held together by mortar.

5. Ina building element of the character described, a hollow block scored u on its outer face to represent a plurality 0 superimposed bricks and to receive a filling of mortar, a mortar filling for said grooves, said blocks provided with a plurality of interlocking wedge shaped projecting portions extending from each end of the block, and alternating with recesses in the body of the block adapted to register with the corresponding projecting wedge-shaped interlocking portions of a similar block placed in adjacent relation, said block having at each end a plurality of vertically disposed the block,.said grooves being adapted to re ister with like grooves in the adjacent bloc whereby the 'oints between the blocks may be sealed by fi ling said grooves with mortar.

6. In a building element of the character described, a hollow block grooved upon its outer and inner surfaces to represent a plu- Leas es g3 rality of superimposed bricks and to receive tions of a similar block placed in adjacent relation. 10

In testimony whereof, I sign this specification in the presence of two witnesses.
