BINDING AND FASTENING MEANS FOR FABRIC BED-BOTTOMS.

Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed December 1, 1919. Serial No. 341,709.

I '0 all whom it may concern:

Be it known that I, ABRAHAM GELMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Binding and F astening Means for Fabric Bed-Bottoms, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to binding and fastening means for fabric bed bottoms, an object being to provide an improved and simplified construction of this character which is also cheap to manufacture and eifective in its use. One of the features of my invention is the provision of a fabric seat having a sewed hemmed edge carrying a metal core with fabric supporting and protecting clips along the edge in the nature of U shaped metal members which are folded over the edge so as to securely embrace the fabric and core with openings therethrough for insertion of the spring hooks for supporting the seat, so that the hooks will support the core and the core support the seat, the clips also protecting the fabric against abrasion by the hook.

In bed bottoms made up of fabric seats it has been found diflicult to secure a construction which will suitably support the fabric bottom and revent a tearing thereof due to the strain requently placed thereon. Various constructions have been used in bed bottoms of this character but some of them have been too expensive for use with the ordinary cheap folding cot. Also in constructions of this kind which have heretofore been used, heavy metal reinforced edges have been provided which not only add greatly to the expense of manufacturing but also increase the weight. Added weight, of course, makes the cot more difficult to handle as these devices are frequently used where they must be quickly folded up and stored away. Also cots of this kind have been used in which fabric bottoms have been provided with supporting means either in the way of spring hooks or leather lacings threaded through openings along the edges but such that the fabric is worn due to the direct contact therewith by the supporting hooks or lacings.

In my improved construction I eliminate these disadvantages by inserting a thln metal core in the hemmed edge of the seat and providing metal clips which are spaced along the edge and so constructed that the supporting strain is placed upon the core as a whole and at the same time protecting the edge of the fabric against abrasion by the supporting hook or lacing.

The present application is a continuation in part of my application for folding cots Serial No. 291,651, filed Apr. 21, 1919, Fig. 6 of the present application being taken from the said copending case.

In the accompanying drawing I have shown several forms of my invention in which Figure l is a view of the end portion of a cot frame with the fabric seat and supportmg springs;

Fig. 2 is a section along the line 22 of Fig. 1. i

Fig. 3 is a perspective view of one form of clip;

Fig. 4 is a view of the clip of Fig. 3 showing it in its fiat state, that is, before being formed up to embrace the edge of the seat;

Fig. 5 is a modified form of clip in which holes are providedinstead of the slot as in the first form of my invention; and

Fig. 6 is another form of clip.

eferring now more in detail to the construction shown in Figs. 1 to 4 I have shown a fabric seat 10 preferably made up of heavy canvas and having hemmed edge 11 sewed at 12 so as to provide an opening in which a metal core 13 is inserted preferably in the form of a suitable wire rod. Spaced at proper intervals along the hemmed edge, and around the entire seat, clips are pressed in the form of U shaped members 14 which are preferably made out of blanks 15 punched from suitable sheet metal. These clips are pressed over the edge so as to embrace the fabric and securely hold it to the core 13, being preferably pressed tight against the fabric and core and held by rivets 16 which pass through the holes 17, 18 of the clip and also through the fabric seats. These clips are also preferably so constructed that an opening 20 is provided through which the hooks on the springs 19 maypass, permitting these supporting springs to engage the core so as to support the core and thereby the fabric seat. That is, the construction is such that the supporting spring 19 will cooperate with the core in such a thereby way that the core will take the supporting strain and thereby support the fabric seat throughout its length. These springs 19 are also booked at their one end into openings in a frame 21 usually provided for supporting the fabric seat. In the use of the cot the seat, of course, is strained in different ways and the supporting springs 19 are pulled in various directions. In order to prevent the hooks on these springs from unduly abrading the fabric of the seat the clips 14, although permitting insertion therethrough of the s ring hooks,

are such that abrasion of the abric is prevented, the clips themselves taking any side or transverse strain of the [spring hooks.

In Fig. 5 I have shown another form of my inventionin which, instead of providing a slot 20 through which the spring hook is inserted, I simply provide holes 20% which are spaced so as to permit insertion of the spring hook into engagement with the core the same as is shown in Fig. 2.

Of course, for the purpose of inserting the spring hook, the clips may be fastened to the seat and then a hand awl or similar implement used to pierce the fabric so as to readily admit the hook on the spring. This is a simple way of doing this and I have found it to be a farmost satisfactory one.

In Fig. 6 I have shown another form of clip in which the clip is placed over the edge and then pressed together so as to securely embrace the parts. This is the particular clip shown in my parent case and will answer the purpose in some cases, as

in lighter beds or cots, but the riveted clip is the preferred form.

For the purpose of illustrating my invention I have shown several different forms but it will be apparent that changes and modifications will readily occur to those skilled in the art and I also contemplate applying it inotlier ways than that shown and therefore do not desire to be limited to the structure shown and described but aim to cover all that which comes within the spirit and scope of the appended claim.

What I claim as new and desire to secure by U. S; Letters Patent is:

Binding and fastening means for cot bottoms comprising a fabric seat having a sewed hemmed edge, a wire core inserted in the hemmed edge, a plurality of individual thin metal U shaped reinforcing clips embracing the edge and extending backof the wire core, each clip having an opening through which a supporting spring is hooked, said openings clearing the wire core so that the springs directly engage the core,

means for securing said clips to bind the fabric to the core so asto prevent relative movement'thereof and protect the fabric against abrasion by any direct transverse pull of the supporting spring, said clip opening being positioned so that the spring book will support the core, and the core will support the seat.

In witness whereof, I hereunto subscribe my name this 28th day of October, A. D. 1919.

ABRAHAM GELMAN.
