speciiication. y My inventionv rela sto bed-s rings' known n,..the trade 'as ovehang. bedgs'prings'also tcf" rabbet-edge .spri'n gs, both-of which overhang theside rails of' the bedstead. In-the overhangcon-struction, to which the invention yis I,incre'particularly designed, the web-sup portingframe has its end bars attached to the upper sides of the side bars to support the web at a higher level than the level ofthe said upper sides of the side bars and'pojecting beyond the outsiders of' theside bars ftocarry/a Wire webv with margins overh'anging l the frame, which'is lade'sirable form of constructiom aiording wider beds with a given Width of bedsteads, said extensions of the.A end bars'beingalso utilized for thebearingpoints of the bed-springs on the side rails of' the bedstead; and my invention consists of improvements in'springebearings of such bedspring frames to rest on the side rails of the bedsteadsfo'r greater elasticity of the bed, preventing noise,and especially to prevent warring, scratching, and disiguring the'en-v Vamel or other finish of the side rails of the bedstead, all as hereinafter described, reference beingmade to 'the accompanying drawings, in whichl l Figure 1 is a plan .view of a bed-spring of the character for which my invention is .designed. Fig. 2 is a detail in sectional eleva-` tion, cna larger scale, the line of the section being approximately at 2 2, Fig. 1. Fig. 3 is to th'e end bar of the bed-spring frame. Fig. 4 is a transverse sectionof the clip on' line 3 3, Fig. 3. Fig'. 5 is a detail in side elevation,y showinga modification of the clip for attachp ing the springs to angle-iron end bars of the bed-spring frame; and Fig. '6 is a detail showing a manner of connecting the spring Without the clip. Fig. 7 is a longitudinal sectionof the spring and clip, showing a solid spring Serial' No: 708,683. (No model.)

with a recess in each end-to receive'the prongs of the holder. v

The frames of the overhang bedlspri'ngs,

for. which my improved bearing-springisf intended, are commonly made of wood bars, as thesidebars a, and the end bars b, Ysaid'en'd bars being boltedto lthe upper sides'of the side bars, as represented in Fig. '2, and `projectng outward of the side bars, asat c, to. support margins d of the wire web overhang ing the side bars a and theside rails eof the' bedstead also; but they are sometimes-made of anglefiron bars a and b', a bracket e" or some equivalent device -being employed` in connecting the side bars and end bars to-v geth'er, the bracket being secured to the side bar, Aand the end bar bbeing boltedor ri-v# eted to the bracket'. As these overhangbedsprings are now-made the `projectingendsg of the end bars rest directly on ythe side rails e-of the bedstead, which is injurious to the' enamel or other finish of the side 'rails by scratching vand marringlit. It is also objec-f .A

ltio'na'ble for beingcreaky and noisy, and the bedfspring sets' lower than .is-desirable fol-the` lproper height 'ofthe wire web above theside rails of the bedstead. To avoid these obje@ tions and also to make the bed more springy, I apply rubber cushion-springs to the unden sides of these projecting end portions cof the end bars, which I prefer to make of Ashort sections iof elastic-rubber ubing ot'- comparatively thick and-,rigid web', which i apply side'- wise to the under sides of said-projections and will secure in any approved way, as by a nail t driven through the upper part of theV web of the spring, the lower part of theweb being perforated toadmit the head'of the nail through ill; but the Wayl that I preferY to api ply-them consistsin the employmentofametallic clip comprising a base-plate j, havinga' suitable concave seat 7c inI one side ad ted to the contour of a section of the side su face of `the spring, with aprongl at the ends of `the seat, respectively, said prongs pointing, -inward of the .ends of the ibase-plate. to hook into the openings of the ends of thespring-to retain the springen the seat, the'saidplate having the fiat base (represented inFig's. 2, 3,

and 4) to be fastened on the end portion cof,

, a barb by screws -'inserted `through holes m 'or .parallel flanges o,- adapted to receive between-them the vertical flange p of the an.- gle-lronlgend bar b'fand the binding-strip q,

3 employed-"Ito `Beeurethe turned-down margin 's of the wire weban'd be rivetedthereto, as

shown in Fig. 5.

. To enter the spi-ings in their seats in the 'attaching-plates, 'theyya're powerfully com- IO' {Dressed-lengthwise, as in the jaws o f avise, be'- n'glinserted alittle more than half their diameter between said jaws-and so shortened by the compression thatthe spring-will enter between the. points ofthe prongs into the seat,

Vthe plate being placed'on the spring while so compressed Then as the pressure is relaxed the spring expands into the hooks and `isthus effectually secured.

. The springs are not necessarily tubular.

'TheyA may beV practically solid and either cyflindric'alorof other form, with a recess in each en d toreceive the prongs of the holder,`

as shown inv Fig. -7, or lthe indentures of the' prongs in the ends of the `compressed springs 'fof solid form may serve.

Isepa .be attached to any overhang or rabbet-edge The spring an'd attaching-plate may be sold rately from the bed-springs, as theycan bed-spring already in use by any one capable of. screwing the attaching-plates to the end bars 'ofthe bed-spring.

"It will be seen that the special feature of ,myinvention is a very simplec'ontrivance of the lcushion spring, whereby it can be attached directly to the under side of thev projecting end portion of the end bar of the bedspring traine, vso as to avoid the necessity of a special bracket attached to the bed-spring fraine for carrying the cushion-spring, as in the 'Schlesinger patent, No. 583,266.

What I claim as my invention is 1. A- cushion-'spring 4for overhang or rabbet-edge bed-springs consisting of an elasticpad and a baseplate,said base-plate having one side'adapted to be attached directly to thennder side of the overhanging part of thebed-spring, a bearing-seat on the other side. for receiving the elastic pad, and

^ a'hook-prong at each end of said seat, said prongs pointing toward each otherand adapted to engage the ends of the 4pad respectively and securely hold itin 'its seat in the baseplate.

2. The combination with a bed-spring having overhang extensions of the sides at th; ends to rest on the side bars of the bedstead, of cushion-springs attached directly to thel under sides of said overhang extensions of the bed-spring, said cushion-springs con- .sisting of au elastic pad, a base-plate, said base-plate having one side adapted to be attached to said overhang extensions, a bear-
