Application led J' une 9, 1915. Serial No. 33,092.

To all whom t may concern Be it known that l, MORRIS LowY, a citi- Zen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bed-Springs, of which the following is a specification.

The present invention relates to improvements in bed-springs, having a woven wire or spring constructed bottom or web. In springs of this type the free ends of the wire strands of the woven fabric are clamped between binding or retaining strips, which are riveted together and connected by helical springs with the angleiron transverse bars of the supporting frame. In constructing these bed springs, obviously each set of binding or retaining strips must be provided with two sets of registering apertures, that is one set for the clamping rivets and the other set for the helical springs. ln a similar manner must in the angle-iron transverse bars of the supporting frame be formed openings for the helical springs, care being taken that these openings be in alinement with the corresponding perforations in the binding or retaining strips. The perforating and riveting work must be performed with great care in order to obtain a durable and marketable article. Although special tools and jigs are used for the perforating operations, it may be stated that a large part of the manufacturing and assembling expense is taken up by the perforating and riveting work.

One of the objects of the present invention is to reduce the cost of production of the bed springs by doing away with the perforating and rivetingrwork, or by reducing such work to a possible minimum, thereby producing a structure which is simple, dura# ble and convenient to assemble.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter fully described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claim without departing from the' spirit or sacrificing any of the advantages of the invention.

Two of the many possible embodiments of the invention are illustrated in the accompa* nying drawings, in which Figure 1 is a plan view of a bed spring constructed in accordance with the present invention; Fig. 2 is a vertical section taken through a portion of said spring on a larger scale; Fig?) is a plan view, partly insection, of the detail shown in Fig. 2; Fig. 4 is avertical section taken through a modiiication of the invention; and Fig. 5 is a plan view, partly in section, of the modification shown in Fig. 4f.

Broadly speaking, the invention consists in embedding the free ends of the wire strands of the fabric, forming the spring mattress bottom, and also reinforcing bars in retaining strips which consist of a suitable composition, metal, alloys of metal or any other suitable substance which forms, upon setting or hardening, a rigid or stiff bar; the reinforcing bars being disposed in front of those portions or sections of the retaining strips which are engaged by the means which connect the said retaining strips with the angle-iron or other transverse bars of the supporting frame.

Referring now more particularly to Figs. 1 to 3, inclusive, the numeral 10 indicates the angle-iron transverse bars of the supporting frame. These members are attached, for instance by rivets, to corner brackets or blocks 11, having sockets, in which are seated the usual side bars 12 of the frame. The brackets are provided with sidewardly extending lugs 13, which rest upon the side rails 14: of the bedstead in the usual manner. The spring mattress bottom is made of a suitable fabric, indicated at 15, the free ends of its wire strands being embedded in retaining strips 1.6, in which are also embedded reinforcing bars 17. In each retaining strip is formed in rear of the reinforcing bar 17 a row of apertures 18 for a purpose hereinafter to be described. The retaining strips may be made of metal, alloys of metal, compositions 0r other suitable substances which form, when set or hardened, a rigid or stiffl bar. The process of embedding the free ends of the wire strands and the reinforcing bars in the bodies of the retaining strips depends entirelyrup'on the nature or lproperties of the material or which said strips are formed. For instance, if the material be metallic, the elements to be embedded are placed into a suitable mold, the molten metal or alloys of metal poured thereinto, and left to congeal. Into the apertures 1S extend the inner ends `of helical stretcher springs 19. Both ends of these springs are bent, for' instance, into hook-shape, as clearly shown in Fig. 2 of the drawings. One of the ends of each spring 19 is hooked into an aperture 1S, and the other end into a perforation 20 in one of the angle-iron transverse bars of the supporting frame.

The operation and assembling of the bed spring is obvious from the foregoing.

It is to be observed that by this improvement a very simple, inexpensive and practical ineans is provided for connecting the wire mattress bottom with the transverse angle-iron bars of the supporting frame, and that by this construction the riveting work is entirely Vdone away with and the perforating work reduced to a possible minimum, in the spring illustrated in Figs. 1

t'o 3, inclusive, there being no other rivets Vbut those which secure the cerner brackets er blo'cl'rs U11 to the angleeiron transverse bars 10. Inasmuc'h as the reinforcing bars 17 are disposed in front of the inner hookshaped ends of the helical stretcher springs 19, the latter will be safely anchored in the said retaining strips, and the said stretcher springs cannot tear 'or break away portions of the retaining strips if subjected to undue tension by a heavy weight placed upon the mattress bottoni.

A modification of the invention is illustrated in Figs. -fl and 5 of the drawings. This structure differs from the one above described in that the retaining strips lack the apertures 18 above mentioned, the inner hook-shaped ends of the helical stretcher springseinbracing the inner edges of the said retaining strips. The reinforcing bars serve in this case also a twofold purpose, to Wit: to strengthen the retaining strips and to provide an anchorage for the helical stretcher springs.

It is obvious that instead of the woven wire fabric bottoms, any other suitable bottoins, for instance wire link bottoms, may be made rise of without departing from the spirit of the invention.

That I claim is A bed spring 'comprising a supporting frame including transverse end members, a wire fabric bottoni hai'fing the free ends of its wire strands inclosed by mold-fashioned retaining strips, helical stretcher springs having their inner ends hooked onto said retaining strips and their outer ends conneeted with said transverse end members, and reinforcing members embedded in said retaining strips and disposed in front of the curved portions of the hook-shaped inner ends of said stretcher springs.

Signed at NeivYork, in the county of New York, and State of New York, this 24th day of May, A. D. 1915;
