FURRNG CONSTRUCTION.

Application led February 17, 1928. Serial No. 254,990.

It is the obj ect ofmy inventionito provide' new and improved means whereby ceilings and walls may be prepared for receiving plaster, stucco or other plastic coating, or have facings applied thereto; further, to provide novel means whereby my improved attaching means is imbedded in the concrete or other material of which the ceiling or wall is composed; further, to provide novel means wherebyattaching tension members, such as wires, have protruding portions which are temporarily arranged in the plane of the ceiling or wall; and, further, to provide' an inset arranged to receive the protruding portions of the wires in bent form during construction of the wall or ceiling, the inset being provided with means capable of being arranged in protruding relation to the ceiling or wall to server as spacing means for the lath or other facing means.

The invention lwill vbe further readily understood from the following description and claims, and from the drawings, in which latter:

My improved device is arranged to 'be used in connection with ceilings, walls and other parts of building structures, and is arranged to be attached to the'ceiling or to the inside or the outside of ythe wall, for receiving plastering, stucco or other material, usually applied in plastic form, although sheet material, for instance, wall board, may also be used in connection therewith, and I shall hereinafter for brevity and clarity refer to the ceiling, wall or other part to which my improved device is attached,

as the foundation.

AIllustrating an application of my improved device, 11 represents the mold of a usual concrete ceiling structure, the mold defining the bottom` form of the floor 12, which is instanced of concrete, poured into the mold and allowed to harden in usual manner. The mold is eXempliiied as defining a channel 13 intow'hich the concrete is poured for forming one of the strengthening ribs 14;l inthe concrete Hoor or partition 12 which separates stories of abuilding, the ribs extending downwardly at the ceiling of the room.

These ribs are recurrent in the concrete structure, and it is usual to apply the plastered ceiling' below the planeof the lower ends of the ribs. It is also usual to install the piping for heatingand other service and electric wiring ini thespaces between 'the' ribs, which spaces are usually known as domes. My improved device provides means whereby the domes are free to receive suoli installation, andv protruding parts for attachlng lath or other material are avoided on the ceiling during such installation, which is usually done after the concrete is set and the forms are removed but before 'further manipulation of my improved device.

It has been difficult heretofore to con# veniently, properly and economically install lath for plastering or other coating to cover a concrete foundation. To overcome these objections I have provided an inset 15, shown as a pan, the bottom 16 of'which'is provided with apertures 17. Side walls 18 extend from thebottom and are preferably slantedr inwardly or toward each other. The inset is provided with a spacer member normally I l' parallel with the pan and arranged to be extended outwardly from the pan.` Thus one of the walls is Vprovided with a flange 19, which is normally bent along the bend 20 substantially parallel vwith the bottom 16.

For a ceiling structure, the pan is in upside down relation in the foundation and for an upright wall Structure the pan `is in upright relation in the inner face or the outer face of the wall.

A wire 21 is bent to form a lock 22, which is arranged to lock with the concrete, when vthe concrete has been poured thereabout and set, so as to properly resist vthe' strains of the ceiling or facing arranged to be held by the wire. the form of a loop, with the stretches 23, 24, of the wire extending therefrom and passing through the apertures 17. The free ends of the wire are bent in reverse directions or curled, as indicated at 25, and arranged along the inside of the pan between the bottom 16 and the flange 19. Then'wire forms a tension-member.

vThe pan is preferably provided with closed corners 26, whichjavoid the entrance into the pan of fluid and ingredients of the poured concrete. The spacing flange is bent inwardly, .preferably so as to be received within the plane of the outer edges 27 of` the ,side walls, so that these edges of the side walls may throughout meet with the form, in order to close the pan, and thereby prevent'the entrance into-thepan of fluid or ingredients from the poured concrete. The pan is attached to the form, as by means of nails 28, received through holes 29 in the bottom of the pan and nailedl into the form. 4 Y V 'When the concretehas been poured and set, and the form removed, the spacing flange 19 and the portions25 of the wires are exposed at the outer face of the foundation, but do not protrude therefrom. The piping and wiring lis then preferably installed in the domes. The flange is then bent outwardly, so as to project from the outer face of the foundation, and the wires are also bent, so as to project outwardly for use.

The outer edge'ofthe flange is provided with a notch 3l.

A Stringer 32, shown as a channel-bar, is received in this notch crosswise of the flange, and the projecting ends of the wires are arranged loopwise about the Stringer,

and are twisted, as shown at 34, preferablyy at the sideV of the stringer, to Afirmly sup port the channel-bar with relation tothe foundation,and to urge the channel-bar toward the flange 19,which` acts as a spacing part `for spacing the Stringer from the foundation.

My improved insets are arranged at suitable distances apart in the foundation, and the stringers extend across numbers of the insets and are secured thereto. Rows of these insets and stringers are r.arranged siiitable distances apart for properly supporting the lath 35. The lath is supported, preferably by means of wires 36 arranged loop wise around the stringers and through apertures 37 in the lath, the wire being twisted, as shown by the twist 38, for nrmly securing the lath to the stringers. The twist 38 is preferably flattened against the lath, and the twist 34 is preferably at the side of the Stringer between the foundation and the lath so asV not to interfere with the proper piane of the lath. Lath of various 'char- This lock is shown in acters may be employed, this lath being usually metal lath. @ther material or coating such as wall-board, or other material, may also be suitably secured to the stringers.

It is desirable that the lath be in an even plane for convenience and economy in plastcring. It often occurs that the face of the foundation in which the insetsV are lo cated is not. in an even plane. If such uneveness occurs, it`may be corrected by means of my improved device, by arranging the flange 19 at various angles with relation to said surface. If the flange extends at right angles to the surface, the Stringer is supported at greatest distance from said sur-` face. If it is desiredto arrange thestringer -atless distance from a4 portion of the lsurface ofthe foundation which bulges outwardly, for instance as shown at 39, then the flange 19 is bent to extend at ardifferent angle thanat right angles tothe surface, for instance as shown in Fig. G, whereby the uneveness in the foundation is corrected so that the coating is Vin an even plane.

,Flanges of'different lengths may also be employed. l

then the form is removed, the form is pulled away from the insetand the nails 28. The concrete is, however, received under n the inwardly bent side walls of the pan, for

forming retaining rims tOlaround the margins ofthe pan, for retaining the pan firmly in the foundation, and making itV easy to manipulatevthe flange 19 for bending the same and for bendingand manipulating the wires.

The flange 19 is preferably integral with the pan or the wall of the pan from which i it extends. The pan is preferably yof sheet metal. The pan is preferably dovetailed in the foundationby the retaining rims l10,

which aid in holding the panin place dur-V ingthe bending of the flangeA 19 to Vthe de-V sired extent, preferably at thebend 20. The sheet metal is preferably sufficiently stiff` to properly locate the Stringer at the various inclinationsof the flange 19.

i I have in Fig. 7 shown a different form ofstringer, the striiiger being there shown as a bar 41, the bar being of, suitable length and extending across a number of the insets. The form of str'inger and its cross-sectional dimensions or shape are immaterial, such stringere being selected and the distance'between stringersand between inserts being proportioned according to the weights to'be Supported or strainsto be resisted.

My improved device is especially useful for furring or providing a coating, such as plaster, stucco, or other coating, which is spaced from the foundation. My improved construction is furthermore simple and economical in structure and in use, and vit greatly simplifies the attachment'of finishing surfaces to foundations.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:
