provement in Cement Building Constructi'oh, of whichthe following is a specificaner in which they are attached. Prior to.

tion. v

This invention relates to certain improve-v merits in construction of buildings having a wooden frame-Work, or studding, which is covered on the exterior with a veneer of relatively thin cement blocks, and, more particularly relates to certain improvements in cement blocks adapted for such purpose, and the means associated therewith for attaching them to the-studding, and the inanmy invention, cement blocks have bcenprovided with attaching means which comprise a reinforcing rod, having WII'GS, attached thereto, said rod and attached portion of the I wires being embeddedin the block and said some extended beyondthe inner surface of the block and being-adapted to be connected.

to the frame of the'building' to hold the .blocks in place. In the practical employmento'f these attaching means various difiiculties are presented. It is d-ifficult to cast the blocks so that the wires which are at- I tached to the rod will project from their f inner sides, inasmuch as the most convenient method of making the same is to cast them in ashallow mold, and, as the upper surface of the block must bethe finished surface, the side next the bottom must be the inner side of the block, from which the wires must project, furthermore, said projecting wires are liable to be broken in setting the block in place, in which case the lam tire block might be rendered useless.

The object of my invention is to provide the blocks with means, which are adapted to be entirely embedded in the cement at the time the block is cast, so that they do not protrude beyond the surface of the block, thereby enabling the block to be cast in a shallow mold and its upper surface to be finished as desired before the cement hardens, and avoiding the necessity of having attaching means'protrude through the bottom of the mold, when the biock is cast, said means being adapted to receive attaching means, at any time after the-block has been removed from the mold, or when it is placed in position against the studdmg,

which may be employed to bind the block I =securely to the studding and to draw the blocks closely together at their ends. I accomplish this object by the means shown in the accompanying drawing, in Which:-

Fig. 3is an elevation showing the inner side of the buildihg 'studding with the cement blocks attached thereto in amanner embodying my invention. Ifig. 1s a top plan View thereof. F g. 5 IS a cross sectional viewoi'a mold for forming the blocks, illustrating the" method which 1 preferably employ in melt ing said blocks, Fig. 6 is a detaii-view of the iastener-receivmg means which 'i em- I ploy.- v

According to my invention, in the process of manufacture of the cement bloclrs a,;-a reinforcing rod 1) is embedded in the middle of each block, said rod being of sufficient lengthto extend from end to end thereof,

and azseries of U-shapod tubes 0 are also embedded-therein, and arranged to extend around said rod with their ends flush with the inner surface of the block.

in practice, the blocks are cast in shallow molds, as d, preferably between two and three inches in depth," and of the required length and breadth, and when the mold is,

partly filled the rod b is laid therein. The ends of the tubes are closed with some readily removable means, as'a cork stopper c, and then said tubes are inserted in the cement astride the rod and pressed down until their ends touch, or bear against the bottom of the mold, as shown Figs. 5 and 6. The filling of the mold is then completed, so that the rod and tubes are covered, and the top surface is finished as desired. Nu-

'merous diderent eiiects' in'finish may be conveniently secured on the upper surface of the block when cast in this manner, as-

it is convenient of access and special finishing material may be applied to time surface before the cement hardens.

After the cement hardens and is removed from themold, a cement block will beprovided having one or more reflexed passages therein, which open to the inner side of the block, or the side which is toenga ge the wall of the structure when in position thereon. 7 r

is the construction or the building, the

studs f are arranged at the customary distance apart, and the blocks a are made of studs, so that the inner sides of the blocks rest thereagainst, and the cndsot the blocks of one course terminate directly opposite the middle of the blocks in the ad acent COUUISQS.

Either before, or after the blocks are placed in position against the studs, the corlts e are removed from the ends of the tubes 0, and a length of strong, flexible wire 9 pushed through each tube, this being easily ossible, as said tube is of curved form. hen said tubes 0 are placed in position at the time the blocks are cast, they are arranged so that, when the blocks are in position against the studs, each tube will be closely adjacent one sideof a stud. Further, I preferably arrange one of said tubes adjacent each end of each block, so that the wires which are placed therein protrude ad jacent the adjacent sides of the studs which the block partly overlaps, and arrange two tubes adjacent the middle thereof, so that the wires therein are disposed at opposite sides cf'the stud which engages the middle portion of the block. Each end of one middle wire is then attached to the corresponding end of the other middle wire by merely twisting said ends together, after they have been passed about the inner side of the stud,

so that the block is firmly attached to the stud, and, in like manner, the ends of the wire in each of the end tubes are passed about the adjacent stud and connected to the wires in the adjacent tube of the next block. In fastening said end wires the blocks are drawn together so that the cement which is placed between the ends of the blocks will be pressed therebetween, making a close joint. 1 or convenience in illustration, the ends of the wires are shown as twisted together at the inner sides of the studs, but, in practice, they are preferably twisted together at the intermediate sides, so that there will be practically nothing to interfere with the application of the laths to the inner side at any point.

It will be observed that, after a length of wire has been cut 0d and inserted in a tube, so that both end-portions of the wire extend from the ends of the passage formed thereon, the wire may be readily slid back and forthas desired, so that the relative lengths of said protruding end-portions may be varied, as may be convenient in attaching' the same to the studs.

The erection of the wall will be continued when it is finished, its interior may be provided with a coating of waterproof material to prevent the passage of moisture therethrough and the usual lath and plaster finish will then be applied.

The U-shaped tubes, while serving primarily as a convenient means of connecting the attaching Wires after the blocks are cast, also serve to protect the wires from moisture entering through the block, so that the possibility that the wires may become rusted away in time is avoided, and, to prevent all possibility that this may occur, the tubes are refcrably made of waterproof material.

ile the above described invention is believed to be especially advantageous when used in connection with a building frame composed of studs, beams, posts, and the like, and is more particularly designed, specilically, for use in this connection, it may be employedin connection with the wall of any structure through which the attaching wires may be passed, so that they may be socured on the inner side thereof.
