From the seat, a, and back, b, lof the chair, projections c c extend downward, and `embrace the opposite sides of a base-frame, A, ,which is designed to' rest onthe floor.' Each of the parts c c is connected to the said frame A by meansof a journal, d', extended from the frame, land into the said part c, the same being to enable theehairto be tiltedori such journals.
A roller or barrel, d,arranged between andv having bearings in the cheeksv e e of the frame Ahas two bands, fg, fixed to the lower part of vits circumference, they being wound around .the roller in opposijte directions, and fastened, at or near their upper ends, to the seat of the chair.
In rear of. the roller is a rod, z, which extends from one cheek to theo-ther of the frame A, and serves to support one end ofa bow-spring, which is fixed' to it, This Spring, arranged with respect to the roller, in
manner as representedin fig. 3, is connected to the middle of the lower` part of the roller, means of a ring,
l, and a link or loop, m. Y
The spring, by its arrangement, will operate, with the roller and the bands, to chec'k the chair While-being tilted in either direction',y
By the mechanism. applied to the .chair and its supporting-stand, the chair maybe movoptilted with great ease by and to asitter. v .s l ,it
I claim the arrangement and combination of the spring, the bands, and the barrelor roller, as appl the chair audits stand. l
