BED-SPRING.

SPECIFICATION forming part of Letters Patent No. 477,181, dated June 14, 1892.

Application filed May 2, 1892. Serial No. 431,559. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES KING, a eitizen of the United States, residing at Detroit, in the county of IVayne and State of Michigan, have invented certain new and useful Improvements in Bed-Springs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in bed-springs, and especially to the construction of a spring-Md made of coiled springs connected together; and it consists in the peculiar construction of the connection between the springs and longitudii'lally-connecting wires, whereby the structure is stiitened, and whereby a perfectly-tight joint is made Without any possibility of rattling or looseness.

In the drawings, Figure l is a plan view of a spring-bed embodying my invention. Fig. 2 is an enlarged plan of the edges of two of the coiled springs, illustrating the manner of connecting the springs together and to the binding-wire. Fig. 3 is across-section thereof on line on. Fig. 4 is a cross'section on line y y in Fig. 2. Fig. 5 is a detached perspect ive view of the joint. Fig. (3 is a detached perspective view of the various parts from which the joint is formed.

A is a series of coiled springs.

B is the usual metallic frame at the sides and ends, to which the marginal coiled springs are connected at the sides by means of extensions C at the top and bottom coiled around the frame. These springs are arranged in longitudinal series, and they are connected together and to the frame by means of COYIIIBOtIIlg-WIIOS I) at the top and bottom. These connecting-wires are connected at their ends to the ends of the frame,and intermediate their ends are formed with bends E opposite each coil. The top and bottom coil of each coil-spring has formed therein an eye F by means of a horizontal loop of a length substantially equal to the length of the bend E in the connecting-wire and through which the bond is adapted to engage, as shown in Fig. 8. After completing the coil the wire forming the same extends beyond the coil to form an extension G, which is adapted to be passed through the bend beneath the loop, locking the connecting-wire firmly in the eye of the loop, and then to prevent rattling is bent into the coil II around the top of the loop, firmly clamping all the parts together. This construction, it will be seen, comprises coil-springs having in the top and bottom coil on one side an eye, and on the other side having the ends of the wires secured thereto and formed with an extension adapted to connect with the adjoining coil, and of connecting-Wires extending longitudinally, with crimps or bends passing through the eyes and secured in position by the connecting-wires from the adjoining springs. The result is a spring-bed which is light and durable and with joints connecting the springs, which are secured, and which are so firmly banded together as to prevent any possibility of rattling.

What I claim as my invention is- 1. In a spring-bed, the combination,with the coil-spring having a loop formed at one side of the end coil and an extension of the end of the wire at the opposite side thereof, of a coi'inecting-wire having a crimp or bend adapted to pass through the eye and the connecting wire from the adjacent coil passing through the bend beneath the loop and coiled around the loop, substantially as described.

2. In a spring-bed, the combination of a series of coil-springs, a frame around the same, to which the marginal springs are connected, and connecting-wires connected at their ends to the ends of the frame, bends in the conn ecting-wi res at each spring, loops in the lower coil of the spring, through which said bends engage, and a locking-wire formed by an extension of the lower end of the adjoining spring engaging through the bend beneath the eye and coiled around the eye, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES KING.
