IMPROVEMENT IN RECUMBENT CHAIRS.

Specification forming part of Letters Patent No. 174,627, dated March 14, 1876; application filed June 1 5,1s75.

To all whom it may concern Be it known that I, WILLIAM HEATH, of Bath, of the county of Sagadahoc and State of Maine, have invented a new and useful Improvementin Recumbent Chairs and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l is a top view, Figs. 2 and 3 opposite side elevations, Fig. 4 an under-side view, and Fig. 5 a longitudinal section, of a chair provided with my invention.

In this chair the back A and the seat B are to be or are hinged together, and the seat is provided with a leg-rest, L, which should also be hinged to the seat and have arms a a extending up from it and jointed to the chair-arms O 0, such chair-arms at their rear ends being jointed to the back A. The seat, at or near the middle of each end, I pivot to the supportframe 1), the pivots being shown at b b, and I provide such seat-frame with a deep tie or board, 0, extending across it longitudinally near its middle, as shown. Against one side of the board 0 I arrange a friction-arm, E, pivoted at its outer end to the leg-rest, such arm being connected with the board 0 by a pendulous connection-bar, d, pivoted to the frictionarm and to the board 0. To operate with the friction-bar there is a friction-toggle, F, which, arranged as shown, is hinged to the frontbar 6 of the frame D, and is connected to a lever, H, by a bar, G, which is pivoted to both toggle and lever. The said lever goes through the part c, and is fulcrumed thereto and jointed to another lever, I, arranged in the frame D in manner as shown. A spring, K, fixed at one end to the board 0, bears against the longer arm of the lever H.

From the above it will be seen that not only or otherwise, by means of the friction-arm and toggle, the spring serving to keep the toggle forced up to the friction-arm, and the system of levers enabling a sitter to move the toggle back, so as to enable the friction-arm to readily move with the leg-rest.

By having the seat pivoted at its ends to the frame it will operate to better advantage than if rigidly fixed thereto; but it may be rigidly fixed to the frame, the chair being in other respects as described.

I claim-- 1. In a recumbent chair having attached to its seat B a movable back, A, and a leg-rest, L, connected by arms 0 O a a, as described, a friction-arm, E, applied to the legrest and support-frame B, as set forth, in combination with a clamp or toggle, F, applied to said support-frame and friction-arm, and' provided not only with a spring, K, to force it toward the friction-arm, but with levers H I for drawing it away therefrom, all substantially as described.

2. The seat, pivoted, at or near the middle
