BED-SPRING.

Specification of Letters Patent.

Application filed July 15, 1911.

Serial No. 638,605.

To all whom it may concern:

Be it known that I, J AGUB SOHWARTZMAN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bed-Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention has reference, generally, to improvements in bed-springs; and, the invention relates, more particularly, to improvements in bed-springs made from a wire-woven or spring-constructed metallic fabric, and in the novel means for supporting said fabric.

My present invention has for its principal object to provide a novel construction of frame for spreading the metallic springfabric, comprising a novel construction of corner-bracket or block, adapted to be combined with the cross bars and stretcher bars of the frame, to provide a means for supporting said metallic spring-fabric in such a manner so as to strengthen the longitudinal marginal edges of said metallic springfabric.

In the use of bed-springs of the metallic fabric type, it is usual to spread and support the same with its entire body fiat or horizontal; and in such cases a great strain is placed upon the marginal edges of the spring-fabric, which tends to sag at such marginal edges. This strain is often increased because of the fact that persons fre quently sit upon the edge of the bed, throwing the entire weight of the person upon the marginal edge of the bed-spring. It is the purpose of the invention, therefore, to provide a frame having a novel construction of corner block or bracket with which the metallic spring-fabric is connected in such a manner, so as to turn upwardly the longitudinal margin of said sprlng-fabric,

whereby the same is strengthened at such points.

Another advantage of my novel construction of bed-spring is that it prevents ridges or high spots forming in the middle of the mattress supported by the bed-spring, but rather tending to maintain the high points in the mattress surface at the edges of the same.

Other objects of this invention not at this time more particularly enumerated, will be clearly understood from the following detailed description of my present invention.

The invention consists in the novel metallic bed-spring hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, all of which will be hereinafter more fully described and then finally embodied in the clauses of the claim which are appended to and which form an essential part of this specification.

The present invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a plan view of the end-portion of a bed-spring embodying the principles of the present invention; and Fig. 2 is an elevation of one end of the same. Fig. 3 is a face view of the inner side of a novel construction of corner bracket or block, made according to and embodying the principles of the present invention; and Fig. 4 is a side view of the same, looking in the direction of the arrow w in Fig. 3.

Similar characters of reference are employed in all of the herein-above described views to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-character '1 indicates any suitable wire-mesh or fabric, such as is used in the ordinary construction Patented Nov. 7, 1911.

of bed-springs, the same being provided with the transverse or lateral end-straps 2, and the longitudinal side-straps 3. The said lateral end-straps 2 are provided, adjacent to their rear marginal edges, with a series of suitably spaced perforations 4, in which are hooked the ends of suspension or stretcher-springs 5, the latter being preferably of the coil or spiral type. The novel frame for supporting said wire-mesh or fabric is formed with four corner-brackets or blocks, each corner bracket or block comprising a main body-portion 6, inclined rearwardly and upwardlyfrom its lower portion 7. Connected with the lower inner corner of said lower portion 7 is a socket-piece 8, and extending from the upper end of said inclined body-portion 6 is an upper-portion 9, the upper edge of which turns or curves upwardly from the inner side to the outerside of said upper-portion. Said body-portion 6, together with its upper and lower portions 9 and 7, is provided with strengthening flanges 10 which extend at right angles therefrom. The upper curved edge of said upper portion 9 is likewise provided with a curved flange 11 conforming with the curve of said edge, and extends at right angles to the said upper portion.

Extending outwardly from the upper portion 9 of each corner bracket or block is a lug or projection 12, the same being provided with a flange 13 extending at right angles to said lug or projection, the said flange 13 extending rearwardly to meet said curved flange 11, and having connected therewith a jut or shoulder 14. In like manner, the said lug or projection 12 is joined with said upper portion 9 by means of a similar jut or shoulder 15, thus forming a seat for receiving the end of a head or cross-bar 16 adapted to be connected with, and adapted to extend between the laterally opposite corner brackets or blocks. Said head or crossbars 16 are secured in their connection with said corner-brackets or blocks by means of rivets, or any other suitable fastening devices. Said head or cross-bars 16 are made in the form of an angle iron providing a horizontal flange 17 each horizontal flange 17 being provided, adjacent to its free marginal edge, with a series of suitably spaced holes or perforations 18 adapted to receive and retain certain of said suspension or stretcher-springs 5 of the spring-fabric. In like manner, the said curved flanges 11 of the upper portion 9 of said corner-blocks or brackets are also provided, adjacent to their free marginal edges, with a plurality of perforations or holes 19, adapted to receive the remaining suspension or stretchersprings 5 of said spring-fabric. Since the said perforations or holes 19 extend up the curved or turned surface of said curved flanges 11, it will be clearly evident, that, when said spring-fabric is connected therewith, the longitudinal marginal edges of the fabric will be caused to assume an upward turn or inclination, conforming to the curve of each curved flange 11. Such a turn or inclination tends to stifi'en and strengthen the spring-fabric at said longitudinal marginal edges, thus enabling the same to stand greater strains without sagging or distortion, and thereby rendering the center of the spring-fabric uniformly smooth and straight. Furthermore, when a mattress is supported by a spring-fabric thus suspended and arranged, the same is prevented from forming ridges or high spots in the center thereof, and is maintained in a smoother and better condition. Extending between the longitudinally opposite corner bracket-s or blocks are the usual stretcher-rods 20, the ends of which are arranged and secured in said socketpieces 8 of the respective cornerbrackets or blocks.

I am aware that changes may be made in the various arrangements and combinations of the several devices and parts, and in the features of my present invention, without departing from the scope thereof, as described in the foregoing specification, and as defined in the claims appended thereto. Hence, I do not limit my invention to the exact arrangements and combinations of the various devices and parts as herein set forth, and as illustrated in the accompanying drawings, nor do I confine myself to the exact details of the construction of the said parts.
