To aZZ whom it may camera.'

Be it known that I, CLINTON W. SCHALL, a citizen of the United States, residing at Columbus in the county of Franklin and State of Chio, have invented a certain new and useful improvement in Slabs for Building Constructions, of which the following is a specification.

The primary object of this invention 1s to provide slabs for use in erecting lhouses and other structures that may be economically and expeditiously manufactured and erected without the aid of highly skilled labor. @ther objects will appear from the disclosure herein.`

The invention is embodied in the example of slab and art of manufacturing the same herein shown and described, the features of novelty being :finally claimed.

In the accompanying drawing- Figure 1 is a transverse central sectional view of the partly formed slab taken horizontally with reference to its position when finally erected in a building.

F ig. 2 is a similar view showing the slab completed or ready for joining with other similar slabs.

Fig. 3 shows in horizontal section how the slabs are joined to form a straight wall and a corner.

F ig. 4C shows in horizontal section the joint between two slabs as it iinally appears or with the form boards removed from the joint.

The slabs are preferably formed in squares or oblongs of any suitable size. In the views 5 designates a rectangular sheet of what is called expanded sheet metal or lath having a large mesh, say one and one fourth inches. This sheet is laid on -a boa-rd 26 and upon the center of sheet 5 is placed a sheet metal spool 6. Wires, as shown at 8, are secured to the lower sheet at its center and sides, said wires to be bent down at their upper ends to secure the upper sheet to the lower sheet as hereinafter described. Placed near the two ends of the to-be vertical margins of the sheet are strips of plaster of Paris 9 and paralleling these are placed curved wooden form strips l0. Before laying the sheet 5 on the board its opposite edges are slightly bent up as indicated at 5a. Thus prepared the spool 6 and the spaces between the strips 9 and 10 are filled with concrete and the sheet metal 5 covered with a layer of suitable thickness, say one half inch, of concrete or plaster as shown at 11. When the concrete thus referred to has sufliciently set the form strips 10 are removed and upon the filled spool and filled ends is placed another sheet of expanded metal 12 of the same size and form as that first referred to, two of its edges being bent down as shown at 12a and the upper ends of the wires 8 passed through the sheet and bent down as indicated in Fig. 2. The sheets 5 and 12 because of their location may be termed face sheets. Through the open ends of the structure thus formed are passed several horses 13 and upon these horses are supported form boards 1a. These boards 14: are preferably located so as to allow some of the concrete to pass through the mesh of the sheet and thus form on the inner side a layer 15, the application of the concrete being continued to form To hold the wet concrete and prevent it from running over the edges and also for providing a measure to x the thickness of the outer layer 16 boards 17 are located around all the edges of the sheet 12. lin practice and preparatory to applying the concrete to the sheet 12 an open rectangular frame comprising form boards 17 may be placed around the partly formed slab, the

edges 5El and 12a being bent in to permit this. When the layers of concrete 15 and 16 have hardened t e slab is removed from the frame 17 and the horses 13 and boards 14 taken out of the open ends of the slab.

Tn erecting a wall the slabs thus formed are placed edge to edge as shown in Fig. 3the lips 5 and 12a being bent out and inter-connected at several points by wires 18. The vertical openings between the thus connected slabs are then closed at opposite faces of the wall by form boards 19 and the pocket thus formed filled with concrete pouredI into the upper end of the pocket. When the concrete thus poured h-ardens and the form boards 19 removed a wall having a joint like that shown in F ig. 4 is presented. lt will be noted that because the sheet 5` was laid on a board the plaster or cement l1 passes through the mesh of the metallic sheet and spreads upon the board so that upon hardening it forms a smooth an outer layer 16.,

coat or surface as though regularly lastered. A White coat can be added i desiredwhen the wall is erected.

As depictedI in Fi 3 the slabs as rst described are admirab y ada ted to form corners. In constructing suc corners I form with a suitable mold an angular piece 21 having 'a m'etallic core 22. The two Webs of this angular piece are joined at intervals with metallic'straps 23. A corner piece thus formed is placed to lap on the ends of the two slabs meeting at a corner, as shown in Fig. 3, the edges 5? andi 12a being first wired together as indicated Vin said vlew. When the corner piece is thus applied a pocket is formed into the yupper end of which the concrete can be poured and when such concrete sets and hardens the meeting edges of the slabs and the corner piece are all bound tightly together by a solid core of concrete. It will be noted that the curved form of the core in the straight Wall forms a key that locks the adjacent slabs from lateral movement with reference to each other, either inward or outward. The wall can be erected in courses of these slabs either with alinin or broken joints vertically. It is-preferable to erect them with vertically alining joints because such construction lessens multiplication of sizes andi continuous vertical air spaces are provided, thus promotin coolness in summer, warmth in winter an freedom from dampness at all times.

In erecting a building with these slabs due provision will, of course, be made for leaving suitable openings for the installation of door and window frames of metal or wood, such frames being preferably so constructed as to aid in tying together the adjacent slabs in fixed relation to each other and the wall as a whole.

The forms of ,the parts can be changed without departing from the gist of the 1nvention as claimed.

What I claim is:

V1. A wall constructed of hollow slabs laced edge to edge said slabs each consistlng of two paralleliy spaced face sheets of foraminate metal adapted to receive, be penetrated b and retain a plastic material, coats of p astic material applied to and covering said sheets except at the vertical margins thereof, and reinforced Vertical spacing fillings of plastic material between and connecting said face sheets within the margins thereof, and plastic fillings between said slabs covering the aforesaid margins. 2. A hollow slab for constructing buildings consisting of two parallelly spaced face sheets of foraminate sheet metal adapted to receive, be penetrated by and retain a plastic material, coats of plastic material applied to and covering said sheets except at the vertical margins thereof and reinforced vertical spacing fillings of plastid material between and connecting said face sheets between the margins thereof, said margins being adapted to be bent inward'to engage a plastic filling between the adjacent edges of two of such slabs.

3. A hollow slab for constructing buildings consisting of two parallelly spacedI face sheets of foraminate sheet metal adapted to receive, be penetrated by and retain a plastic material, plastic material applied to and covering said sheets except at margins thereof and spacing and bracing posts of plastic material connecting said facing sheets at the interior of the slab, said posts having a reinforcing member connecting the foraminate sheets.
