To all whom "it may concern:

' .Be it knownthat-I, MATTHEW WM. FLoTo. United States, and a resident of the cityof Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im roveinents in Wire Fabrics and Attaching eans Therefor; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marke thereon, which form a part of this specification.

This invention relates to improvements in wire cloth fabrics and attaching means therefor and more particularly to that class set forth in my prior ap lication for patent filed July 24,-1905; Seria No.*270,924.-

In constructing the bottoms of beds, couches, etc., it has been usually-customary kinds of springs in constructions are unnecessarily e pen'sive and are exceedingly difficult to repair. In some instances woven wire netting or a wire cloth fabric made of separable units has been employed and is fastened to the end and side a members of the spring frame. WVhere the :iof the fabricor springs and it therefore sags a fabric be fabric is thus-engaged to rigid side bars or rails there is, of course at all times a hard ridge, .alongeach side and for this reason said constructions have not heretofore been adaptable forcouches and davenports owing to the discomfort and fatigue caused by the rigid Furthermore in the construction prevent the occupant from lying on the edges of the bed and a considerable area for this reason cannot be utilized. Again where the sides of the fabric are yielding side bars the resiliency of the fabric is not evenly distributed over the entire area toward thecenter so that if more than one person occupies the bed both roll toward the middlei It is an object of this invention to provide members or bars are dis ensed with and which affords approximate y equal resiliency over the entire, area of the bottom'and in which the objections heretofore caused by sa ging are eliminated. is also an'objectofthis invention to rovide means whereby the fabric when use .for

acouch, davenport, etc, may be stiflened any desiredamount and in which the stifien' be quickly and easily inserted ing means may and removed. It is finally an object of this invention to reduce the number of.units and attaching parts to azminimumand to provide a construction so cheap to manufacture and-easily to be within the reach of all users."

The invention relates tothe matters hereinafter described and more fully pointed out and defined in'the ap ended claims.

.In thedrawings: *igure'l is a: plan view of a device embodying my invention with parts omitted. Fig.2 is an enlarged detail of one of the side units or members. Fig. 3 is an enlarged perspective detail of one of the intermediate units or members. Fig. 4 is an enlarged perspective view of one of the hooks for securing the end of the fabric to the bar or frame. Fig. 5 is an enlarged per spective fragmentary, detail of one corner of the bottom. Fig. 6 is a fragmentary detail illustrating one method of stifi'ening the fabric.

As shown in said drawings: AA" indicate end bars or members of any suitable material which as shown are angle bars having the web directed downward and the flange inwardly. Engaged to said bars at approximately the same distance from each end is'a bracket 0 provided with an internally threaded socketa' to receive the longitudinal' tubular rods o The corresponding sockets on opposite end bars are 0 p0 sitely threaded and said tubular rods i ro tated in one'direction serve to tighten the ,The fabric comprises a plurality ofunits or spring members of which the intermediate units or members B, comprise a wire formed centrally to afford a spiral coil b, havingdivergent arms bb, ,each of which is provided with a hook N, at its outer end, the extremity of which is directed inwardly upon the arm and is then turned outwardly forming a rounded end. The hook of said intermediate units are engaged in the coils. .of the adjacent units and afford together sides. The outer arm of each unit or member B adjacent the sides is in sucha position that it does not engage a coil or loop of an I adjacent intermediate unit.

1 a solid network intermediate the Engaged to the intermediate units or members B at the sides of the fabric are unit or spring members C which each comprise a wiretwisted intermediate its ends to afford directed inwardly in the same general direc tion as the arm 0 and provided with a hook 0 As shown, the arm 0 engages the coil or 100 b of the intermediate units or members an the free arm b. of said members B engages the coil 0 as vdoes also the arm 0", of each side unit or member. structed the coils or loops 0; along each side of the fabric are in alinement. Secured through said alined loops 0 is a rod D of greater size and strength than the units and provided at each end with an eye adapted to engage one end of a helical pulling spring E, the opposite ends of which are engaged to the end bars or members A-A. The coils or loops bc of the units or members BC adjacent the bar or member A are secured thereto by means of fasteners F which are provided atone end with hooks f as before.

described and at the opposite end by a plain hook. The units or members B-'C adjacent the bar A are engaged thereto by means of fasteners G which as shown consist each of one piece of wire turned to form a coil 9 which is engaged by the hooks at the ends of said members or units B0 and the opposite end of said fastener G is bent to engage suitable aperture") in the angle bar A.

The operation is as follows: The fabric is very quickly and easily assembled and by the use of the novel units or members 0 and the hook G, the use of a great number of independent coils and. half unit members is obviated. The fabric so constructed affords uniform resiliency over the entire area and does not draw from the sides or tend to sag at the middle when occupied. Furthermore there being no side rail a soft edge is assured and the bed is comfortable to its edge either for a seat or as a bed. Should the edge prove too soft or resilient it may be stiffened by increasing the stren th of the springs E or strong wires or rods Tl may be employed which are provided at each end with a hook similar to the hook I) or before described and which engage the longitudinally alined coils or loop I) or c of said units or members B(J;next adjacent the "rod 1), of course more than one line of such rods or wires may be employed if desired and helical springs in that case may be substituted in lieu of the hook f or G in such strengthened line. Said connecting rods a may also be employed to' When thus con tighten the fabric and of course the sockets may be of sufficient depth to admit of considerable lengthenin of the bed.

The unit or mem%er C may be' modified to form a spring hook to engage the rod D if preferred and various modifications in the construction may be made. I therefore do not limit this application as to details, as

obviously they may be varied without deloops and means yieldingly engaging t e ends A of said rods to said end bars.
