SPRING-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 767,374, dated August 16, 1904. Application filed February l2, 1902. Serial No. 93,686. (No model.)

To all 'wh/mt it muy concern:

Be it known that I, GEORGE E. BIGELOW, a citizen of the United States, residing' at lYorcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Spring-Support, of which the following is a specification.

This invention relates to an improved construction for supporting ordinary upholstery- 1o springs-such, for example, as are used in chair-seats, carriage-seats, couches, or which may be employed to advantage in bed-springs or for substantially any purpose where a cushion or spring' seat is required.

The especial object of this invention is to provide a construction for supporting upholstery-springs and to lock the same in place` which can be assembled or put together without the use of special tools.

2o To this end this invention consists of the parts and combinations of parts, as hereinafter described, and more particularly pointed out in the claims at the end of this speciiication.

In the accompanying drawings, Figure 1 is z5 a perspective view, partially broken away, of

a frame having its upholstery-springs supported and locked in position according to my invention. Fig. 2 is an enlarged fragmentary view showing the manner in which the crosswires are hooked in place to fasten a spring onto a main supporting-wire, and Fig. 3 is a fragmentary view of one of the main supporting-wires.

In upholstering chair-seats or other articles of furniture difliculty is `frequently encountered in providing suitable means for supporting and fastening the upholstery-springs in place. For supporting the ordinary upholstery-springs it has been proposed to provide 4o supporting-wires extending acros's the frame which is to be upholstered. In such constructions, however, so far as I am familiar with the same, the upholstery-springs have usually been fastened or locked in place by threading the coils of the springs onto the supportingwires or by using binding-wires which are permanently twisted in place.

In practice upholstery-springs are now made of such stiff wire that in order to thread or turn the coils of .an ordinary upholsteryspring into place on a supporting-wire or other device special tools are required for bending the end of the spring, and even with the use of such special tools and devices the operation of threading an ordinary upholstery-spring 5'5 onto a support is a difficult one, which usually can be performed only by skilled help and then comparatively slowly. To overcome these defects, I have provided a construction for upholstery purposes which can be put together in a simple, direct, and eflicient manner without the use of special tools and which will provide a strongly-braced and connected construction which will not only provide a knockdown construction which can loe assembled without the use of special tools, but which will also support the upholstery-spring in a more permanent and rigid manner than in constructions which have heretofore been employed. To these ends for supporting the 7 0 upholstery-springs I employ main supportingwires which extend across the frame which is to be upholstered, and combined with the main supporting-wires I provide cross-wires which are detachably hooked onto the supporting-wires, the parts being so combined that the act of securing the cross-wires in place will lock the.upholstery-springs in position without turning or threading the coils of the springs onto the supporting-wires. 8O

Referring to the accompanying drawings, for a detail description of a construction embodying my invention, 10 designates a chairseat or other frame which is to be upholstered. Extending across the frame 1() are -the main 85 supporting-wires 11. The said supportingwires 11 are bent up near their ends 12 to form a bow-shaped support which is provided at its eXtreme end with a U-shaped footpiece 13, which is formed in a plane at right angles to the plane of the U-shaped body, the outer leg of the U-shaped foot-piece 13 being long enough to form, in effect, a T-head, so that when the main supporting wires are placed in position on the frame which is to be upholstered the U-shaped foot-piece 13 will hold the supporting-wire from swaying or rocking. The main supporting-wires 11 may be each secured in place by an ordinary wire staple 1-t.

The springs 16 maybe of the ordinary npholstery-spring' type, and cach of the springs 16 is secured in place on its supporting-wire 11 by t-wo short cross-wires 1T. The short cross-wires 1T are substantially of a buttonhook shape at each end.

The manner in which the parts are assembled is most clearly illustrated in Fig'. 2. As shown in this tig'ure, in order to secureaspring' 1G in place a supporting' wire 11 is lirst threaded between the coils near the base of the spring'. The inner ends of the cross-wires 17 are then hooked onto the supportingwire 11 within the coils of the spring' 16, so that when the outer ends of the cross-wire 17 are swung' up and hooked onto the side supporting-wires 11 or the outside wires 15 (shown in Fig'. 1) the spring' not only will be securely fastened in position, but the supporting'-wires will be tied together, so as to form a strong' and efficient construction which will provide a more rig'id support than constructions which have heretofore been employed.

ln practice l have found that the tension of the parts is suiiicient to hold the springs in place upon their supportingwires, so that the same are not liable to move longitudinally on the supporting-wires. 1n some cases, however, it may be desirable to provide positive stops for preventing' the longitudinal displacement of the springs upon their supliiorting'- wires, and when it is desired to do this the main supportingwires 11 may be roug'hened or maybe provided with upwardly-projecting' lugs or teats 18, as shown in Fig'. 3.

1n shipping' the parts to be used in u pholstering'franies according' to my invention the springs may be nested together and the supporting-wi res and cross-wires may be wrapped in bundles, so that a large number of such iitting's may be made to occupy comparatively small space. r

in the drawings l. have illustrated. the application of my invention to frames in which live springs are employed. llt is to be understood, however, that the number of main supporting-wires and number of spring's secured thereon can be varied as desired.

l am aware that numerous chang'es may be made in practicing' my invention by those who are skilled in the art without departing from the scope of my invention as expressed in the claims. 1 do not wish, therefore, to be limited to the construction I have herein shown and described; but

llfhat 1 do claim, and desire to secure by Letters Patent of the United States, is

1. 1n a construction otA the class described, the combination of a simporting-strip, an upholstery-spring' having' one coil thereof engaging' the simporting-strip, two cross-wires having' their inner ends connected to the supporting-strip within the coil of the spring',

i i i and means for fastening' the outer ends of the cross-wires so that the spring' will be locked in place on the supporting-strip therebv.

2. 1n a construction of the class described, the combination of a frame, supporting'- strips extending' across the frame, upholsterysprings, each having' one coil engaged by a simporting-strip, two cross-wires secured on each supporting-strip within the coil of each upholstory-spring', and means for holding' the Outer ends of the cross-wires in place so that the upholstery-spring's will be locked in place thereby upon the supportiiig-strips.

3. 1n a construction of the class described, the combination of a frame, main supporting'- strips extending' across the fraaie, upholsterysprings, each having a coil eng'ag'ed by a supporting-strip, and two cross-wires for each spring' having' their inner ends detachably hooked upon the supporting-strip within the coil of the upholstery-spring', and having' th cir ends extending' out in opposite directions, and provided with hooks for engaging' a supporting-strip at each side of the supporting-strip to which their inner ends are hooked, so as to lock the upholstory-springs in place.

4L. In a construction of the class described, the combination of a supporting-strip, an upholstery-spring' having' one coil thereof eng'ag'ed by the supportingstrip, two cross-wires having' their inner ends secured on the supporting-strip within the coil of the spring', means for holding' the outer ends of the crosswires in place, and thereby locking' the upholstery-siiiring' on its supporting-strip, and lugs or projections for preventing' the crosswires from sliding' longitudinally upon the supporting-strip. l

5. As an article of manufacture, a main supporting-wire for use in constructions of the class described, consi sti ng' of a bow-shaped body portion, with foot-piecesat its ends lying' in a plane at rig'ht angles to the plane of the body portion, said foot-pieces being' formed by a lJ-shaped bend of wire having' an extending end.
