SPRING-HOLDER.

SPECIFICATION forming part of Letters Patent N 0. 425,997, dated April 22, 1890.

Application filed August 13,1889.

T0 aZZ whom it may concern:

Be it known that we, CHARLES II. ECOLES- TON, of Oxford, and GEORGE II. HEBBARD, of Sherburne, in the county of Ghenango and State of New York, have invented a new and useful Improvement in Spring-Holders; and we do hereby declare that the following is a full, clear, and exact description of the same.

Our invention is a holding-bracket for spiral springs,'and while we have specially designed the same for use with rocking-chairs and have illustrated the invention as applied in this connection, it will be understood that it maybe used in other situations with equally good effect.

Our objects are to provide means for holding and connecting a spiral spring to the part desired to be placed under tension, which will not require any special formation of the spring other than. spiral, .and will not necessitate screw-threading or crooking the end of the wire.

Further, our object is to furnish a means for holding the spring which will permit quick and easy detachment of the spring and the parts held thereby without removing screws or the su pporting-bracket, and which will also permit adjustment to properly align the parts or to place a different tension thereupon.

ith these ends in view the invention consists, essentially, of a bracket having a socket to receive a coil of the spring and adapted to receive holding pin, which retains said coil therein.

In the drawings, Figure l is a side elevation of the rocker of a rocking-chair and the base upon which it rests,with the spring-connection in place. Fig. 2 is a transverse section of the same. Fig. 3 is a perspective view of the bracket and part of the spring, and Fig. 4 a longitudinal sectional view of the same.

In the drawings, Ais the rocker; B, the base upon which it rests and moves; C, the spiral spring extending between these parts, and D D the brackets, which connect the ends of the springs with the rocker and base B, respectively. The brackets consist of a baseplate d, having screw holes for attachment to the parts and a rectangular extension 6 off at one edge intended to receive and support one Serial No. 320,594. (No model.)

of the coils of the spring, and while it may be variously adapted for this purpose we prefer to make the extension with a socket f, which is formed with curved bearing-surfaces f, to receive the coil. The edges of the socket embrace the coil and hold it securely against displacement in the direction of its length. The extension is connected with the baseplate at its ends only, and this leaves a central opening 9, and as the bottom of the socket is formed with an opening 2 at its central part the coil of wire when in place will have an exposed portion 3, extending through be yond the bottom of the socket, and for the purpose of completing the securing of the coil a pin 4, preferably headed and wedgeshaped, is inserted between the exposed part of the coil and the edges of the socket, which are notched at 5. This wedge prevents outward and circumferential displacement of the coil and provides a rigid detachable connection. It will be noticed that any ordinary spiral spring can be used with this holding device, the coil itself being utilized to form the connection instead of threaded ends adapted to receive nuts or hooked ends. The spring can be easily detached and the parts disconnected for packing or storage by with drawing the wedge, and this connection allows the adj u stmentof the spring circumferentially in cases where through improper placing of the brackets a circumferential tension is created and the rocker and base forced out of alignment thereby, this being effected, of course, without removing the bracket. By removing the wedge also the tension of the spring can be increased by stretching it and bringing another coil in connection with the socket, or the reverse adjustment may be as readily effected. The brackets can be used with either side up, and thus they are adapted to small or narrow rockers and bases.

It will be obvious that the bracket may be used in other situations than that described above, as between the standard and the seat of a tilting-chair.

Ve claim- 1. In combination, the spring, the bracket having a base portion, and a horizontal hearing portion for the spring-coil, said bearing IOG portion having a vertical opening formed therein, and a removable pin inserted in said opening, extending transversely across the coil and retained by its frictional contact with the coil and the wall of the opening.

2. In combination, the spring, the bracket consisting of the base, and a socket portion extending therefrom and adapted to receive the coil, said socket having an opening through its upper and lower Walls, and a pin extending transversely through the socket and through said openings and transversely across the contained coil, substantially as described.

3. In combination, the spring, the bracket consisting of the base, and a socket portion extending therefrom adapted to receive the coil, said socket having a bottom opening through which the coil projects, and openings through the walls, and a removable-pin inserted through the openings in the Walls and bearing upon the projecting or exposed part of the coil, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
