irons, secured in a firm manner to the rear of the seat A. The back G is provided with a frame, H, which is hinged to the inside of the back-frame, to a cross-piece, I. At or near this cross-piece I commences a suitable groove. From each of the front inner-corners of the frame of the back G into these grooves fits the clamp-frame H, allowing sufficient space at each side for the angle-irons, so that the back may be raised up or lowered easily. To the bottom of the clamp-frame His a crosspiece, K, into which is secured a nut, L, and
to the bottom of the back-frame G is a crosspiece, M, into which is Secured the hand-screw N, upon the outer end of which is a suitable knob, to be grasped by the hand to tighten or release the gripe or bearing brought against the angle-irons, the ends of which fit into the groove or opening between the back-frame Gr and the clamp-frame H. Thus, by loosening the hand'screw N, the pressure is released and the back may be raised or lowered to the point desired, when a turn or two in the opposite direction will bring the clamp-frame toward the back-frame, and the same is secured firmly in position.
