CLARENCE H. FREDERICK, OF KENOSHA, WISCONSIN, ASSIG-NOR TO THE SIMMONS MANUFACTURING COMPANY, OF KENOSHA, WI$CONSIN, A' CORPORATION OF WIS- CONSIN.

' BED FABRIC.

Application filed June 20, 1914.

To all whom it may concern:

Be-it known that I, CLARENCE H. FRED ERICK, a citizen of the United States, residing in the city of Kenosha, county of Kenosha, and State of Wisconsin, have invented certain new and useful Improvements in Bed Fabricsfl'ef which the following is a specification.

My invention relates to improvements in bed fabrics and refers more particularly to that type of bed fabric which is built up of a series of longitudinal link chains arranged in parallel relation and connected together by means of cross-links engaging the links of the longitudinal chains.

The salient objects of my invention are, to provide an improved form of wire link fabric in which the cross-links of the fabric are positively positioned without danger of slipping or interference with the other members of the fabric; to provide an improved construction by which the tension trans mitted by the cross-links is prevented from separating, stretching or bending the longitudinal links of the fabric; to provide an improved construction in which the links are of comparatively simple form and cheaply and economically manufactured,

and, in general, to provide an improved bed fabric of the type referred to.

My invention consists in the mattershereinafter described and more particularly pointed out in connection with the accompanying drawings, in which- Figure l is a plan view of my improved bed fabric; Fig. 2 is a section of Fig. 1 taken on the line 2-2; and Fig. 3 is a fragmentary section taken on the line of Fig. 1.

The wire fabric shown is of the general type shown and described in U. S. Letters Patent No. 758,920, issued to O. R. Hunt lllay a, 190i.

Referring to the drawings, it will be seen that thefabric as a whole is constructed of longitudinal. chains each made up of a series of similarly formed links -i hooked into ongagcn'icnt with one another, these links being connected together by cross-links 5. Each of the longitudinal links 4: is symmetrically formed with an eye (3 at one of its ends, this eye being engaged by the free ends of the other end of the adjacent link which are bent around the eye into hook form, as shown very clearly at '7 in Fig. A. short distance above the llOOrI end of each of the Specification of Letters Patent.

Patented Sept. 7, 1915.

Serial No. 846 295.

tion of my improved fabric it will be manifest that with this method of forming the longitudinal links it is impossible for the cross-links to slip or become displaced, since they are positively retained in position by the sides of the bights 10 formed in the ends of the longitudinal links, and, obviously, it is equally impossible for the eyes of the longitudinal links to become displaced. The spreading of the open ends of the longitudinal links due to the tension of the crosslinks 5 is obviated by the twist 8, which also prevents any possible tendency for the cross links to travel up the longitudinal links toward the eyes 6. It will be seen also that the links of the fabric are of extremely simple form and can be constructed Jill a comparatively small number of operations of the automatic machinery by which these longitudinal link chains are constructed, and, in addition, the form of the link is such that every part of the Wire is effective for performing its pa. ticular function and there is no waste of material caused by unnecessary bends or complicated shapes,

The fabric may be folded both transversely and longitudinally and when so folded it occupies comparatively small compass and there is also little danger of the links snarling or catching when the fabric is to be again unfolded in its normal flat position.

Although I have described and shown what I consider to be a preferred embodiment of my invention, it is obvious that certain changes may be effected in the details of the fabric without departing from the spirit of my invention, and in my case I do not desire to be limited in the use of my invention except as specified in the appended claims.

, I claim 1. A wire link bed fabric, comprising a plurality of similarly formed longitudinal link chains arranged in substantial parallelism, each link being made from a piece of Wire bent upon itself intermediate its ends to form the eye of the link, and the two ends of the wire being bent to form a pair of hooks at the other end of the link, said hooks engaging the eye of the adj aoent link of the chain, the link being given a longitudinal twist adjacent its hook ends and being provided with opposing bights adjacent .the hooked ends, and cross-links engaging said bights and connecting together the adjacent longitudinal chains of the fabric.

2. A Wire link bed fabric, comprising a plurality of similarly formed longitudinal link chains arranged in substantial parallelism, each. link being made from a piece of wire bentupon itself intermediate its ends to form the eye of the link and the two ends of the wire being bent to form a pair of hooks at the other end of the link, said hooks engaging the eye of the adjacent link of the chain, said link being given a longitudinal twist and provided with a pair of opposed bights intermediate the twist and its hooked end, and cross-links engaging said bights for tying the longitudinal chains together.

3. A wire link bed fabric, comprising a plurality of similarly formed longitudinal link chains arranged in substantial paralbights contiguous to said twist, and crosslinks engaging said bights for tying said chains together.
