SPRING-SEAT.

SPECIFICATION forming part of Letters Patent No. 288,608, dated November 13, 1883.

Application filed December 9, 1882. (No model.)

.To all whom it may concern:

Be it known that I, WALLACE H. BATE, a citizen ofthe United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented an lmprovementin i Spring-Seats, of which the following is a full,

My present invention relates to that class of seats in which springs are employed to enable the same,when occupied, to" tilt or incline downward; and. my invention Consists in a seat pivot'ed at its front and having one or more springs and a support therefor located under its rear, said seat being disconnected from the back or support,` against which the back of the occupant bears, whereby ease and comfort are promotedV and the liability of slipping forward avoided, my said invention being adapted for use as a chair, settee, or wag- Cnseat. Y

To enable others skilled in the art to uuderstand and use my invention7 I will proceed to l describe the manner in which Ihave carried it out.

In the said drawings, A A represent the two front legs; B B, the two rear legs, which are integral with thetwo respective side pieces forming the back D, the top of the latter sloping to the rear of a vertical plane passing through the tops of the rear legs,and forming `an inclined support for the back of the occupant ofthe chair-seat C, thesides of the front of which or the ends of a cross-bar, a, thereunder are pivoted directly to the tops of `the 4( two front legs, A A, no leg-frame being interposed. Under the rear of the seat is located a spring, c, the topof which is secured to the bottom of the seat, and the bottom of the spring resting on a transverse bar, d,whichis located upon the upper rungs, e. One spring only is shown; but two or more may be .employed when located and arranged in a manner similar to that c-zl e., interposed between the bottom of the seat C and the transverse bar d. The seat has no` connectionwith the back D. lVhen a person occupies a chair of my construction, the weight is brought to bear upon the rear of the seat, which tilts downward against the resistance oi the spring or springs c, and when the seat is relieved of pressure it instantly returns to its original horizontal position. a comfortable reclining-chair of simple andV economical construction being thereby provided.

l claim- The combination, with a frame provided with a back, of a seat capable of movement independently of said back, said seat pivoted or hingedat the front of the frame, one or more springs and a support therefor attached to the frame, said support and spring or springs being located under the seat, substantially as and for the purpose set forth.`

YVALLACE H. BATE.
