BED-SPRING.

Application filed October 3, 1914.

To all 10 from it may concern:

Be it known that I, Monnrs 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.

lhe present invention relates to improvements in bed springs; more particularly to those having a woven wire or spring constructed bottom or web.

These bed springs usually comprise a spring mattress bottom made of woven fabric, the free ends of the wire strands of which are clamped between binding or retaining strips which are riveted together and provided with suitably spaced perforations in engagement with helical springs, the other ends of which are seated in openings in angle-iron transverse bars of the supporting frame, said transverse bars be ing attached to corner brackets or blocks carrying the usual side bars. In constructing these bed springs, obviously each set of binding or retaining strips has to be provided with two sets of registering perforations, that is to say one set for the clamping rivets and another set for the helical springs; in 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.

It has been proposed heretofore to do away with the perforating and riveting work, but, as far as known, these attempts were unsuccessful for the reason that, while some of the perforating work was saved, additional stamping work had to be done, which together with the increased cost of assembling did, instead of reducing the cost of manufacturing, materially increase the same.

One of the objects of the present invention is to produce a bed spring or wire mattress Specification of Letters Patent.

without perforating or riveting work, thus providing a structure which is simple, durable, easy and convenient to assemble, whereby the cost of the article is greatly reduced.

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 claims 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 claims without departing from the spirit or sacrificing any of the advantages of the invention.

A few of the many possible embodiments of the invention are illustrated in the accompanying 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 an enlarged scale; Fig. 3 is a plan view, partly in section, of the device shown in Fig. 2; Fig. 4 is a vertical section taken through a modified construction; Fig. 5 is a plan view of a portion of the device shown in Fig. 4; Fig. 6 is a vertical section taken through another modification of the invention; Fig. 7 is a plan view of a portion of the device shown in Fig. 6; Fig. 8 is a front elevation of a detail of the bed spring shown in Figs. 6 and 7; Fig. 9 is a perspective view of a modification applicable to the bed springs shown in Figs. 6 and 7 Fig. 10 is a front elevation of a corner bracket or block; Fig. 11 is a side elevation thereof; Fig. 12 is a perspective view of a further modification of a bed spring constructed in accordance with the present invention; Fig. 13 is a perspective View of a still further modification of the invention; Fig. 1 is a front elevation of a helical spring suited for use in conjunction with the device shown in Fig. 13; and Fig. 15 is a front elevation of a clip adapted for connecting helical springs with the supporting frame of bed springs.

Broadly speaking, the invention consists in embedding the free ends of the wire strands of the fabric, forming the spring mattress bottom, and also the ends of the helical springs, which are to be attached to the transverse bars of the supporting frame, in retaining strips that are constituted of a suitable composition, metal, alloys of metal, or any other suitable substance that forms, upon setting or hardening, a rigid or stiff bar. Instead of embedding in said retaining strips the helical springs, there may.

be embedded therein suitable means with which the said springs may be brought into engagement. The helical springs may be provided with clips, that are adapted to clasp or hold fast on the transverse bars, or the said springs may engage such clips, so that said bed spring or wire mattress is made or set up without the usual perforating and riveting operations.

Referring now more particularly to Figs. 1 to 3, inclusive, the numeral 20 indicates he angle-iron transverse-bars of the supporting frames. These members are attached, for instance by rivets 21, to corner brackets or blocks 22, having sockets 23, in which are seated the usual side bars 24: of the frame. The brackets are provided with sidewardly extending lugs 25, which rest upon the side frames 26 of the bedstead in the usual manner. The corner brackets or blocks may be of any suitable construction, and the same do not form part of the present invention as far as the device illustrated in Figs. 1 to 3 is concerned. The spring mattress bottom is made of a suitable fabric, indicated at 27, the free ends of its wire strands being embedded in retaining strips 28, in which are also embedded the inner ends 29 of helical stretcher springs 30. The

. the reinforcing bars in the body ofthe 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. In other cases, for instance, the elements to be embedded may be placed between strips of the material in its soft state, the latter compressed, and held under compression until it sets. Again, in other cases the elements to be embedded may be placed into a mold containing a powder-like substance, which is then heated or mixed with suitable liquids, to produce a paste-like substance that will form a rigid bar when set. The other ends of the. helical springs 30 are bent in the form of clips 32, comprising, for instance, horizontal portions 33, abutting against the horizontal flanges of the angleirons 20, and vertical portions 3% that abut against the outer faces of the vertical flanges of the angle-irons and are bent backward, as clearly shown at 34-, the backwardly bent portions embracing and gripping the lower section of the vertical flange of the angleiron. The springs 30 are, obviously, suitably spaced apart, the distances between the same or the number thereof depending wholly upon the weight which the bed spring is intended to carry.

The operation and assembling of the bed spring is obvious from the foregoing. From the foregoing it will also appear that by this improvement a very simple, rigid, inexpensive and practicable means is provided for connecting the wire mattress bottom with the angle-iron transverse bars of the springsupporting frame, and that by this construction the perforating and riveting work is entirely done away with in connection with the manufacture of bed springs, in the spring illustrated in Figs. 1 to 3 of the drawings there being no other rivets shown but those which secure the corner brackets or blocks 22 to the angle-iron transverse bars 20.

The modification shown in Figs. t and 5 of the drawings differs from the one above described in that the inner ends of its helical springs 35 are embedded in the retaining strips 28, and their outer ends are hookshaped, as clearly shown at 36. These hookshaped ends engage clips 37, which grip the transverse bars 20 of the supporting'frame. The clips 37 may be of any suitable construction. In the case illustrated they comprise a wire bent back upon its middle portion 38 to form two diverging horizontal. strands 39, which rest upon the horizontal flange of the angleiron 20, and are then bent downward vertically, as shown at 40, and I back at 4:1 in parallel relation to the sections 4-0, thereby being capable of embracing and holding fast on the lower portions of the vertical flanges of the angle-irons. Instead of the clips 37, those illustrated in Fig. 15 may be used. These clips, denoted by the numeral 37, are similar to the clips 32 above corner brackets or blocks 44, which grip the said tubular bar. Lugs 45, upon the said corner brackets and projecting through openings 46 in said bar, prevent a turning movement of the latter upon the said brackets. One of the helical springs used in connection with this tubular bar is shown in detail in Fig. 8 of the drawings, and denoted by the numeral 47. Its inner end is embedded in the manner above described in the retaining strip, while its outer end constitutes a clip in the form of an annulus or ring; 48, that embraces the tubular bar 42. If helical springs similar to those shown in Figs. 4 and 5 are to he used in connection with the tubular transverse bar 42, clips of the type shown in Fig. 9 may be mounted upon the said bar. Each of these clips, denoted by the numeral 49, comprises a wire bent back upon its middle portion and forming two strands that are bent into ringshape, the free ends 51 of each strand being hooked or otherwise fastened to itself near the middle portion of the wire, whereby an car 52 is formed at said middle portion, into which the helical spring may be hooked.

In the modification shown in Figs. 10 and 11 of the drawings, a corner bracket is illustrated, which differs from the one described in connection with Figs. 6 and 7 of the drawings in that its recess 43, into which a tubular transverse bar 42 is to be placed, is formed in its top. In mounting upon the brackets, shown in Figs. 6, 7, 10 and 11, the tubular bars, the said bars are placed into the recesses in a manner that the lugs 45 project through the openings 46 in said bars, after which the outer ends 53 of the recessed portions of the blocks are bent by a hammer or other suitable tool over the tubular bars.

A further modification of the invention is illustrated in Fig. 12 of the drawings. In this modification a spring mattress with side guards is shown, said side guards serving to prevent the spreading of the stuffed mattress that is placed upon the spring. The woven wire fabric constituting the bottom of the spring mattress is shown at 54. The side guards 55 may be of any suitable construction, and formed either integral with and bent up from the bottom, or attached to the bottom in any approved manner. In the case illustrated in Fig. 12 of the drawings the side guards are shown as of woven fabric and made integral with the bottom 54. The free ends of the wire strands of both the bottom and the side guards are embedded in retaining strips 56, comprising each a horizontally extending portion 57 and two vertically extending sections 58, which may be made integral with the section 57 or attached thereto. It is preferable to make the sections 58 integral with the section 57. In the latter case a U-shaped reinforcing bar 59 extends through the entire lengths of the retaining strips, that is to say through the horizontal portions and through both vertical sections thereof. Thev retaining strips 56 may be connected with the transverse bars of the supporting frame of the bed spring, for instance, by means of helical springs 59 of the type shown in Fig. 9 of the drawings. In such cases obviously the transverse bars 60 of the bed spring must be made in tubular form. Upon these tubular bars are mounted brackets 61, which are connected with the vertical sections 58 of the retaining strips by helical springs 62. The inner ends of these springs are embedded in said vertical sections, while their outer ends are engaged with inwardly turned projections 63, forming hooks.

A still further modification of the invcn-' tion is shown in Fig. 13 of the drawings, differing from all those hereinabove described in that in the retaining strips, denoted by the numeral 64, are embedded wire loops or eyes for engagement with hookshaped ends of helical springs. The other ends of these helical springs may be formed in any suitable manner, for instance they may be formed as clips (Fig. 14), or as rings as shown in Fig. 8 of the drawings, or finally as hooks for engagement with clips of the type shown in Figs. 4, 5 and 15 of the drawings, or for engagement with openings in the angle-iron transverse bars of the supporting frames of the ordinary construction.

The several forms of bed springs herein described are all alike in one respect, that is to say they each comprise a wire fabric bottom, the free ends of the wire strands of which are embedded in retaining strips, said retaining strips having also embedded therein means for attaching the same to the transverse bars of the spring supporting frame. This last named means may either be made in the form of helical springs which are adapted to engage directly the said transverse bars, or by the intermediary of clips;

or the said last named means may be made in the form of wire loops or eyes for engagement with helical springs.

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

It is to be observed that the several clips described herein in combination with the helical springs, or without them, may be used for connecting woven wire or other bed bottoms of the old type with their supporting frames.

What I claim is 1. A bed spring comprising a supporting frame including transverse end members, a bottom having its ends embedded in retaining strips, the bodies of said retaining strips being made of the same material throughout, and helical springs having their inner ends also embedded in said retaining strips for connectlng the latter with said transverse end members.

2. A bed spring comprismg a supporting i frame including transverse end members,

a bottom, mold-fashioned retaining strips inclosing the ends of said bottom, and means connected to said retaining strips and trans verse end members for holding said bottom on its supporting frame under tension, said last named means having its inner ends also inolosed by said retaining strips.

8. A bed spring bottom comprising a Wire fabric having the free ends of its Wire strands inclosed by mold-fashioned retaining strips, and reinforcing means Within said retaining strips.
