TO ALL PERSONS lO WHOM THESE PRESENTS MAY COME:
-Be it known that I, CHARLES W. CNANT, oi' Gardner, in the county of Worcester, and State of Massachu- Betts, have invented a new and usefullm'proveiuent in Rocking-Chairs; and I do hereby declare the same to be fully described in the following speeificntion, and represented in the accompanying drawings, of Which- Figure 1 is a. side elevation, l i
Figure 2 a. rear elevation, and
Figure 3 a vertical and longitudinal section of a chnir provided with my invention.
I'n the said drawings, A denotes the sen-t ofthe chair as provided with a back, a, and arms o r arm-rests b, and also with u pair of rockers, ec. These rockers are arranged below, and nre connected to the seat and rest on the eross-bar d of a supporting-frame, B. The said frame B consists-of two open vertical side Aframes, e e, connected by the bar d. Besides the rockers, there is an arch-piece C, extended down from the seat, and with respect tothe cross-liar d, as represented. On the middle of the Asaid cross-bar a spring, d, is fastened, it being projected in opposite (lirections'from the bai'. At or near its two ends the said spring is fastened to the areb- The middle of the spring, it will be perceived, is itrrangerl'on a level with the tops of those partsvof the bar' d en ,whicll rockers rest. The spring and the arch-piece operate to restore the chair-sent to its normal or horizontal position, and to gradually arrest the chair during either movement while a. sitter mny'be rocking it. The spring and arch-piece serve also to hnldtlie rockers down upon the bar d, and in eonsequence of the arrangeare prevented from sliding on, and sons to wear into the ment of the spring, the rockers, while in movement surface or surfaces on which theyare supported.
I claim the' arrangement, as well as the combination, of the spring D and the arch-piece C with the chair-seat A, the rockers c c, and the supporting-frame Bthereof, the whole being toA operate substantially as described.
