Specification of Letters Patent.

Patented March 24, 1908.

Application filed June 14, 1907. Serial. No. 378,998.

To all whom Lt may concern:

Be it known that I, ALBERT WEBORG, a citizen of the United States, residing at i Jamestown, in the county of Chautauqua and State of New York, have invented a new and useful Furniture-Spring, of which the following is a specification.

This invention relates to spring seats for chairs and the like and its object is to provide a novel arrangement of springs having means for securelyholding them in proper relation at all times so that the same can not become separated as a result of usage.

A still further object is to provide auxiliary springs for maintaining the main springs of the seat normally in predetermined relation.

Another object is to provide brace strips which are connected to the springs in a novel manner.

With'these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a central horizontal section 5 Fig. 2 is a transverse section through the spring seat Fig. 3 is an enlarged transverse section through the overlapping portions of two of the brace strips and the adjoining whirls of a spring engaged thereby; and Fig. 4 is a detail view of one of the brace strips.

Referring to the .figures by characters of reference, l, 1 represents a plurality of double cone springs arranged preferably in pairs, the lower whirls of the springs being connected to a frame 2 by means of clips 3. The lower ends of the springs are also bent outward as at 4 and hooked around the frame to further insure a durable connection between the parts. The upper whirls of the springs are adapted to be connected to an upper frame 5 in the same manner and all of the springs are further tied together by means of links 6 or in any other preferred manner. In order that the central or contracted portions of the springs may be maintained in proper relation at all times brace strips have been provided. TWO sets of these strips are used, to wit, longitudinal strips 7 and transverse strips S. The longitudinal strips have lugs 9 outstruck therefrom at regular intervals, said lugs being arranged in airs. These strips are adapted to be slipped between the central or smallest whirls of the springs so that said whirls will surround the lugs as shown particularly in Figs. 1 and 3. The several pairs of springs are connected iu this manner by these longitudinal strips, after which the springs of each pair are further connected by the transverse strips 8 which are slipped between the intermediate or small whirls of the springs and are also formed with outstruck lugs l() which are surrounded by the whirls. This arrangement of strips holds the central portions of the springs positively spaced apart at predetermined intervals and in order that the springs may be prevented from twisting after being placed in engagement with the strips 7 and 8 braces 1 l are arranged diagonally between the end strips S and the longitudinal strips 7 and are riveted or otherwise fastened to said strips. The strips 7, S and 11 therefore form a rigid rectangular frame and after said strips have been slipped. into the springs and secured together in the manuel' described it becomes impossible for the central or contracted portions of the springs to move out ol predetermined relation.

In order that the two frames 2 and 5 may be further maintained normally in substanw tially parallel planes a series of supplemental springs are preferably used. These springs are in the form of coiled wires and one of them, 12, is secured at its ends to opposite sides of fraaie 2 and is coiled around the lower whirls of the intermediate pair ol springs 1 and around the link connection 6 therebetween. Two other elongated coils 13 are connected to opposite sides of the top frame 5 and coiled about the adjoining whirls of the intermediate pair Aof springs 1 and are then crossed andy coiled about the intermediate whirls of said springs after which said coils are again crossed and secured at their ends to opposite sides of the lower frame 2, the lower whirls of said springs 1 being also engaged by the springs 13, as shown particularly in Fig. 1, Another coiled spring 14 connects opposite sides of the top frame 5 and is interwoven with the upper whirls of the intermediate springs 1 and with the link connection 6 therebetween. This arrangement of supplemental springs tends to considerably reinforce the central portion of the seat which is subjected to the greatest strain and these springs, in view of their particular arrangement serve to greatly assist in maintaining the two frames 2 and 5 in substantially horizontal planes. They also tend to prevent the intermediate portions of the springs l and the connecting strips therebetween from moving laterally in relation to the frames 2 and 5.

The preferred form of the invention has been set forth in the foregoing description but I do not limit'myself thereto7 as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and l therefore reserve the right to make such changes as fairly fall Within the scope of the claims.

Vhat is claimed is:

1. A spring seat or the like comprising a plurality of coiled springs, superposed frames secured to the springs, lapping spacing devices interposed between intermediate whirls of the springs and engaging opposite sides of the frames, and inclined spring coils extending upwardly and downwardly respectively from the spacing devices to the frames.

2. A spring seat or the like comprising a plurality of coiled springs having contracted intermediate portions, frames surrounding and secured to the end portions of the springs, overlapping spacing strips having their overlapped portions interposed between the intermediate whirls of each spring, said overlapped portions having oppositely extending projections surrounded by said whirls, and transversely and diagonally disposed'spring coils engaging opposite sides of the frames.

3. A spring seat or the like comprising a plurality of coiled springs having contracted intermediate portions, frames surrounding and secured to the end portions of the springs, overlapping spacing strips having their overlapped portions interposed between the intermediate whirls of each spring, said overlapped portions having oppositely extending projections surrounded by said whirls, transversely and diagonally disposed spring coils engaging opposite sides of the frames and the end and intermediate whirls of the adjoining springs.

4. A spring seat or the like comprising a plurality of coiled springs having contracted intermediate portions, frames surrounding and secured to the end portions of the springs, overlapping spacing strips having their overlapped portions interposed between the intermediate whirls of each spring, said overlapped portions having oppositely extending projections surrounded by said whirls, transversely and diagonally' disposed spring coils engaging opposite sides of the frames and the end and intermediate whirls of the adjoining springs, and transversely extending coiledv springs connecting the sides ofeach frame and engaging the end whirls of adjoining springs.

ln testimony that l claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
