BED-SPRING.

Specification of Letters Patent.

Patented Feb. '6, 1917.

Application led March 3, 1915. Serial N o. 11,8()6.

To all 'whom it may concern:

Be it known that I, MORRIS LowY, a citizen 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.

rIhe 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, thewoven fabric are clamped between binding or retaining strips, which are riveted together and connected by helical springs with the angle-iron transverse bars of the supportingframe. In constructing these bed springs, obviously each set of binding or retaining strips must be provided with two sets of registering perforations, that is one set for the clamping rivets and the other set -for` the helical springs. Ina 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 might 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 riveting work, or by reducing such work to a possible minimum, thereby providing a structure which is simple, durable, easy 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 theaccompanying 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 append ed 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 accompanying drawings, in which Figure l is a plan view of part 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. 3 is a plan view, partly in section, of .the-detail shown in Fig. 2; and Fig. t is a plan view, partly in section of a modified construction.

Broadly speaking, the invention consists in embedding the free ends of the wire strands of the fabric, yforming the spring mattress bottom, and also thev means which are to be engaged by the helical springs, that are to be attached tothe transverse bars of the supporting frame, 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.

Referring now more particularly to Figs. l to 3, inclusive, the numeral 2O indicates the angle-iron transverse bars of the supporting frame. These members are attached, for instance by rvets,to corner brackets or blocks 21, having sockets, in which are seated the usual side bars 22 of the frame. The brackets are provided with sidewardly eX- tending lugs 23, which rest upon the side frames 24 of the bedstead in the usual manner. The spring mattress bottom is made of a suitable fabric, indicated at 25, the free ends of its wire strands being embedded in retaining strips 26, in which are also embedded eyelets 27. Through the retaining strips extend reinforcing bars 28 for the well known purpose. rIhe retaining strips may be inade of metal, alloys of metal, compositions or other suitable substances which form, when set or hardened, a rigid or stiff I bar. The process of embedding the free ends l of the wire strands, the eyelets and the reinforcing bars in the bodies of the retaining strips depends entirely upon the nature or properties of the material of 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.

With the eyelets 27 are engaged the inner ends of helical stretcher springs 29. Both ends of these springs are bent, for instance, into hook shape, as clearly shown in Fig. 2 of the drawings. One ofY the end-s of each spring is engaged With an eyelet 27, and the other end hooked into a perforation S0 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 improve ment a very simple, inexpensive, and practicable means is provided for connecting the Wire mattress bottom with the transverse angle-iron bars of the spring supporting frame, and that by this construction the riveting Work is entirely done away with and the perforating Work reduced to a possible minimum, in the spring illustrated in Figs. l to 3, inclusive, there being no other rivets but those Which secure the corner brackets or blocks 2l to the angle-iron transverse bars 20.

The modification shown in F ig. l of the drawings dilers from the one above described in that the retaining strip, denoted in this case by the numeral 31, is provided along its outer edge with projections 32, in which the eyelets 27 are embedded. Other- Wise the construction and operation of the elements are the same as those described in connection With Figs. l to 3, inclusive.

VIt is obvious that instead of the Woven WireI bottoms, any other suitable bottoms, for instance, Wire link bottoms, may be made use of Without departing from the spirit of the invention.

What I claim is A bed spring, comprising a supporting frame including transverse end members, a bottom having its free ends inclosed in moldfashioned retaining strips, eyelets in said retaining strips, said strips being molded around said eyelets, and helical stretcher springs having their free 'ends hooked into said eyelets and their outer ends connected with said transverse end members.

Signed at New York, in the county of New York, and State of New York, this 24th day of Feb., A. D. 191,5.
