SPRING ATTACHMENT FOR ROCKING-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 440,516, dated November 11, 1890.

Application filed June 22, 1886.

To all whom it may concern:

Be it known that I, ASHER B. STEVENS, a citizen of the United States, residing at New Bridge, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Spring Attachments for Rocking-Chairs, of which the following is a full, clear, and exact description.

This invention relates to the now common connection for the rocking portion and base of the class of chairs designated base or platform rockers or rocking-chairs, wliichconnection comprises a closely-coiled spring about as broad as long, or of greater diameter than length, and having its end coils firmly connected to metallic brackets, which in turn are attached to the base and rocking portions of the chair, respectively, two ora set of such connections being applied to the chair within its base and rockers and serving to unite the base and rocker port-ions and at the same time permit the free rocking motion against the tension of the spring, the recovery of the spring assisting in restoring the rocking portion to balance, all as usual in this class of devices.

My invention consists in a spring-attaching bracket for rocker-springs in which the sole has arms projecting from the base-plate to such a length as to receive the end coils of the spring or springs within them for over half the circumference of the spring, so that when once in place the spring cannot work loose, but will be rigidly held in engagement with the bracket.

The invention also consists in various details of construction, substantially as hereinafter particularly set forth and claimed.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1 is a front elevation of one of my improved spring-connections with the lower part of the spring broken away. Fig. 2 is a plan view, Fig. 3 a vertical section, Fig. 4 a modification in plan View, and Fig. 5 a plan, of a twin or compound spring connection.

The mode of applying devices of the class to which mine appertains is so well known that I have deemed it unnecessary to show and describe the parts of a chair of the kind to which my invention is applicable.

Serial No. 205,889. (No model.)

tially as indicated in Fig. 1, where the spring,

is broken away to show this feature. This sole is extended or projects from the plate, as arms cl cl, to an extent greater than half the circumference of the spring they receive, and they follow th e'line of curvature of the spring, as in Figs. 1, 2, 3, and 5, or they may be tangent to the diametrical points of the spring,

as in Fig. 4. These arms have the external vertical flanges e to prevent lateral displacement of the springs. The ends of the arms 61 d are preferably beveled or tapered, so as to facilitate the attachment of the spring to the bracket, and this connection is effected by simply forcing the arms and sole of the bracket between the end coils of the spring, so that after the spring has passed into the sole and arms beyond its diameter it snaps right into place and cannot be removed except by force and by prying open or lifting its end coil. For additional security and to prevent any possibility of the spring turning on its own axis on orin the bracket, Iprovide a notched web f on the inside of one arm and enter into said notch the inbent end 9 of the spring. This absolutely prevents any accidental dislocation of the spring, though it might be dispensed with, as indicated in Fig. 4.

In Fig. 5 I have shown these same features applied to a duplex or twin-spring attachment.

In my invention the spirality of the sole and arms conforming to the spirality of the spring it follows that the spring must stand straight, and hence there is no need of rights and lefts.

With my present construction of the spring retaining and embracing arms extending from the bracket a distance greater than half the circumference of the spring I am enabled to hold the spring by its sides only, and need no intermediate engaging device.

Instead of bending inward the end of the spring to engage the notched Web, it may be bent outward to engage a notch in the outer rim or flange. This deflected end of the spring in either case is snapped into its notch or depression and is held there by the force of the spring.

In my application, Serial No. 190,082, filed bracket on the same side of the diameter of the spring parallel to the face of the plate being nearer together than the extremes of such diameter, substantially as described.

2. A bracket having a plate, a sole, arms projecting from said sole forward of and beyond diametrical points next said arms, the opposite spring-holding points on the arms of the bracket on the same side of the diameter of the spring parallel to the face of the plate being nearer together than the extremes of such diameter, and flanges on the outer edges of said arms to hold and retain the spring to and on the bracket against motion in any direction, substantially as described.

In testimony whereof I have hereunto set my hand this 17th day of June, A. D. 1886.

ASHER B. STEVENS.
