Letters Patent No. 70,756, Jated November 12, 1867.

IMPROVED SPRING ROGKING-GHAIR.

TO ALL WHOM IT MAY CONOERN:

Be it known that I, EDMUND SMITH, Jr., of' the city and county of Worcester, in the State ofi-'Massachusetts, have invented au improvement in Spring Rocking-Chairs; and I do hereby declare that the following is a, full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention is applicable to that class of chair which has a stationary frame or stool below, and separate*- frorn the seat and back, and is not designed to form a spring seat, or, in other words, to have much if any directv perpendicular spring, but to give au easy rock back and forward, at the pleasure of' the occupant. To these ends its nature consists `in placing bracings springs between the stool and seat, in such a manner that they tend to keep the seat in a level position, yet by their elasticity allow it to tip back and forward, and give the rocking.

motion desired.

Figure 1 is a side view of a chair with my improvements.

Figure 2, showing the arrangement of the springs on the stool, the scat being removed.

A is the seat, B the back, fast to the seat, C C the legs, D the top of stool, made low enough to allow room for the springs a a and a', which are fastened at their ends to the top D and seat A, they being placed crosswise, as shown in fig. 1. This position gives the bracing stability desired, and leaves the springs to control the tip or rock.

I am aware that rocking-chairs have been made with the feet or legs stationary; and it is evident that more springs might be used, or spiral ones combined with those shown, and my improvement applied to all kinds or forms of chairs, cradles, or similar articles of furniture that it may be desirable to rock.

In combination with the frame and seat of a chair, I claim the springs a a a, with their opposite ends fastened respectively towards the front and rear of the chair, all arranged and combined substantially in the manner and for the purposes above set forth and described.

In testimony whereof` I have hereunto set my hand in the presence of two witnesses.

E. SMITH, JR. Witnesses:
