THOMAS C. CAREY, OF TRENTON, NEW JERSEY, ASSIGNOR 'IO BLOOM AND GODLEY COMPANY, OF TRENTON', NEVT JERSEY.

BED-SPRING.

Application filed May 27, 1914.

Trenton, in the county of Mercer and State.

of New Jersey, have invented certain new and useful Improvements in Bed-Springs,

of which the following is a specification.

This invention relates to bed springs and more particularly to a novel means for securing the edges of the woven wire fabric to the end bars of the spring frame.

One of the present methods of securing the edges of the woven wire fabric of a bed spring consists in turning the side edges of the fabric over a suitable length of strap metal and then riveting the strip to the horizontal flange of the end bar of the frame. This method of securing the fabric is objectionable, however, inasmuch as the ends of the strands project beyond the edge of the securing strip and are liable to cause injury to ones hands in moving the spring, or to tear the bed clothing.

The present invention therefore aims to provide a securing and binding means for the edges of the fabric, so constructed and secured as to cover the ends of the strands and thereby prevent such injury.

In the accompanying drawings: Figure 1 is a perspective view of one corner of a bed spring, illustrating the improvement embodying the present invention. Fig. 2 is a vertical transverse sectional view therethrough. Fig. 3 is a group perspective view, illustrating parts of the device about to be assembled.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference character.

In the drawings, the numeral 1 indicates in general one of the end bars of the spring frame, this bar being preferably of angle iron material and including a vertical flange 2 and a horizontal flange 3. The usual brackets 4 are secured to the edges of the flanges 2 and receive the ends of the usual side bar 5. The woven wire fabric, which comprises the spring proper, is indicated by the numeral 6.

In order that the securing strip and the binding strip embodying the present invention may be secured to the horizontal flange 8, the said flange is formed at suitable intervals with openings 7 for the passage of Specification of Letters Patent.

Patented Dec. 29, 1914i. Serial No. 841,324.

rivets in the manner which will be presently explained.

The securing strip is indicated by the numeral 8 and is preferably of bar metal and provided at intervals in its length with openings 9 adapted to aline with the openmgs 7 The b nding strip for covering the free ends of the strands of the woven wire fabric is indicated by the numeral 10 and is preferably of relatively thin sheet metal and provided with a flange 11 which initially extends substantially at right angles to the body portion of the strip. The strip 10 is also formed with a number of openings 12 which are designed to register with the openings 9.

in securing the edges of the woven wire fabric to the side bars of the spring frame, each of the said edge portions is folded over that edge of the respective strip 8, which is the inner edge when the strip is secured in place, and is passed beneath the strip and about the other edge thereof, as clearly shown in Fig. 2 of the drawings. The binding strip is then disposed with its body portion beneath the strip 8 so as to cover that portion of the woven fabric which extends beneath the under side of the said strip 8. The rivets 13 are then secured through the open ngs 7, 9 and 12 and headed and after this has been done, the flange 11 is struck down so as to cover the overturned edge portion of the fabric and thereby cover the ragged edge or projecting ends of the strands. In order to permit of this being done, the strip 10 is of course formed of malleable metal.

Referring now to Fig. 2 of the drawing. it will be observed that the flange 11 is of a sufficient width to entirelv cover the projecting end of the fabric and. conscquentlv. the same will be entirelv concealed and will not be liable to cause injury to ones hands or to tear the bed clothing. It will furthe more be apparent that in striking down the flange 11 a rounded edge 1.4 isformed continuously along the securing means and, consequently, when the spring fabric is depressed it may rub along this edge without likelihood of being worn through, as frequently occurs when the strip 8 is the only means provided for securing the edge of the fabric. Furthermore it will be observed by reference to the said Fig. 2, that the flange 11 may partly or Wholly cover the rivet heads 13 so that there Will be no likelihood of the wire fabric catching on these heads and becoming torn. It will also be noted that, inasmuch as the overturned edge portion of the wire fabric is secured between the strip 8 and the body portion of the binding strip 10, there will not be the likelihood for it to wear through that there would be if this portion were merely secured between the strip 8 and the horizontal flange 3 of the end bar.

Having thus described the invention, what is claimed as new is:

The combination with the end bar of a bed spring frame and the woven wire spring fabric, of means for securing the edge of the fabric including a strip of bar metal beneath which the edge of the fabric is passed, the said edge portion of the fabric being folded over the inner edge of the said strip to overlap the upper surface of the strip, a binding strip having a portion disposed against that part of the edge portion of the fabric which lies beneath the said strip, and

having a flange struck over the folded over part of the fabric to extend above that portion of the edge thereof which lies above the strip, the fabric being folded back over the outer edge of the strip and extending above the said strip and the binding strip, and headed fastening elements secured through the end bar of the bed spring frame and through the first-mentioned portion of the binding strip, that portion of the fabric which lies between the binding and first mentioned strips, and through the said firstmentioned strip, the folded over flange portion of the binding strip overlapping the upper heads of the said fastening elements,

whereby to guard the fabric against engagcti ment with the said heads.

In testimony whereof I ainx my signature in presence of two witnesses.
