I P. PELDEN. Rocking Chair.

No. 242,442. Patented June 7,1881.

UNITED STATES PATENT OFFIC.

PETER FELDEN, OF CHICAGO, ILLINOIS.

ROCKING-CHAIR.

SPECIFICATION formingpart of Letters Patent N0. 242,442, dated June '7, 1881. Application filed August 30, 1880. (No model.)

To all whom it may concern Be it known that I, PETER FELDEN, of Ohicago, in the county of (look and State of lllinois, have invented a certain new and useful Improvement in Rocking-Chairs, of which the following is a specification.

The object I have in view is to produce strong, durable, noiseless, and simple springconnections for platform rocking-chairs which will not interfere with the bottom of the seat nor with the cross-rails of the platform, and will hold the chair firmly upon the platform and confine its rocking movement within safe limits, and will prevent both lateral and longitudinal slipping of the rockers on the baserails without the use of stops or guides, and will at the same time give an exceedingly easy movement to the chair-body.

My invention consists in the peculiar con-' struction of the springs and the means for attaching them to the rockers and side rails of the platform, as fully hereinafter explained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is an elevation, of the inside of one of the rockers of the body and one of the side rails of the platform or base with my improved sprin g-connection attached thereto. Fig. 2 is a top view of the spring, and Fig. 3 a cross-section through one of the bracketirons and one side of the spring on line 3 3.

Like letters denote corresponding parts in all three figures.

A is one of the side rails of the platform or base, and 13 the corresponding rocker of the body of a platform rocking-chair, such rocker restingdirectly upon said side rail.

01s a continuous plate-metal spring, theupper and lower sides of which, at thecenter, are

secured, preferably, by rivets to the horizontal wings a of cast-metal bracket-iron D D. The vertical wings I) of these bracket-irons have countersunk holes, through which wood-screws are turned for securing the bracket-irons to the rocker and base-rail. ()11 each side of the bracket-irons the two parts of the continuous plate-spring are bent toward each other, as shown at o, and are then spread apart, and form rounded loops (1. These loops d project considerably more below the upper surface of the inner side thereof is spread apart somewhat, so as to draw them firmly together. The spring, while allowing a free and easy rocking movement within safe limits, has great lateral stiffness, preventing any lateral displacement of the chair-body on the platform. The spring also, by being continuous, and by reason of extending 011 both sides of the bracket-irons, prevents the rocker from slipping longitudinally on the side rail of the platform, since one part of the spring counteracts the tendency of the other part to effect such a slipping movement in rocking. If the spring were made a half-spring-thatis, were extended only on one side of the bracket-irons-it would cause the rocker to slip longitudinally on the base-rail in rocking, and would therefore make a noise. The continuous spring can also be made of lighter steel-plate and cheaper than the halfspring, and,by extending on both sides of the I bracket-irons, it need not project so close to the front cross-rail of the platform.

It will be understood that two of my springconnections are used on each chair, one being secured to the inner side of each rocker of the body and the corresponding side rail of the platform or base.

I wish it understood that I do not claim as any part of my invention the half-spring for this purpose, some of the disadvantages of which have just been set forth.

' What I claim as my invention is 1. In a platform rocking-chair, the combination, with the base-rail A and the rocker B, resting directly upon the base-rail, of the bracket-irons D D, secured rigidly to said rocker and base-rail at or near their center, and the continuous double plate spring 0, bent from a extending on both sides thereof parallel to the single piece of metal and secured rigidly at its center to said bracketirons, such spring extending on both sides of the braekctirons parallel with the rocker and base-rail, and having free ends, substantially as described and shown, for the purpose set forth.

2. In a platform rockin g-chair, the combination, with the base-rail A and rocker B, of the bracketirons D D and the continuous platespring 0, secured to such bracket-irons and basc rail and rocker, said spring; being bent inwardly at c and outwardly to form rounded loops (1 at its ends, which loops extend more below than above the top of the base-rail, substantially as described and shown.

PETER FELDEN.
