` Be it known that I, TORWALD WINTER, of Boston, in the county ot' Snfolk, and State otiMlassachusetts, have invented an Improved Recumbent Chair; and I do hereby declare that the following, `taken in connection with'the drawings which accompany and form part of this specification, is a description of mvinvention sutleientl to enable those skilled in the art to practise it. A

My invention relates toitheV construction of that kind of chairs known as railway or recumbent chairs, which are adapted to sustain and support the body Vin easy position, whether the person in the chair be sitting erect or he leaning back at anyangle, down to an extended o'r nearly horizontal position7 the parts of the chair moving withthe person, so that the whole length of bodyis supported. at any position the person n1ay,assume.

My improvement consists in` the peculiar arrangement-of the arms, leg-rest, and back, with mechanism for locking them in position.

The drawings represent, at A and B respectively, a side elevation anda front view of a chair or chair-frame embodying my improvement. I

a denotes the stationary base; Z1, the back, jointed'to the rear of ythe base, as lshown at A, and having jointed to each of its uprights an arm, c, the front end of which is jointed to and supported by a lever, al, fu1 crumed in the. top rail e ofthe base, a. Each lever d extends through its rail e, and the lower ends of the pair arc connected by a cross-bar, f.' At the centre of this bar is an arm, g, which projects under thefront rail t, and is jointed at its front end to a leg-support onframe, z', which frame is hung at top to the front ends of the side raiis e of the base, a, as shown at B. At the bottom this frame is a foot-board or rest, le, hinged upon arms Z, projecting from the bottom rail m of frame z', the foot-rest swinging down against the arms, as seen at A, or up over them, as seen by the red lines at'AA. n denotes a curved ratchet or rack-bar, hung upon a pin, o, the bar projecting through a slot, p, in the rail/m, and having a foot-piece, g, at its front end. 4The bar also extends through a slot in a cross-rail, r, (seen in dotted lines at A,) and its notches, s, catch into a tooth at the bottom of this slot, the bar being pressed down by a spring, t, so that in whatever positionthe leg-rest may be brought, one f the notches of the rack engages with this tooth, and thereby holds the legaest sta tionary. Y .i l

The -parts being thus constructed and arranged, the operation oi' tho chair will be readily understood. The chair being in upright position, as seen in-eolor at A, when the sitter wishes to rccline he places a foot on'top of thepiece g, and depresses said piece, thereby freeing the racknotch from the catch or tooth. on rail r. I-Ie then leans`baek, keeping his foot on piece (/and `presses back the back frame b, the movement of' which is ,communicatedby arms c and leviers d tothe Vleg-reste', tipping up such rest as the back is depressed, the movable `parte being broughtto a stop, and being locked in position at any point, by releasing the foot-piece g, the

rack Vbeing sprung back into engagement with itscateh at such release. By this means, and without any `movement'of the seat, the chair may be extended so as to bring the seat, leg-rest, and back, into or nearly `required position without useof thel hands'.

into horizontal line, as seen by the red lines 'at A, and lwhen the chair is thus extended the foot-board Ic may be tipped up, as also seen in red at A.

'It will be seen that this construction is very strong, that the parts cannot easily get loose or out ot`place, that the arrangement is simple and inexpensive, 4that the arrangement of the parts which move is such as to oier no impediment to upholstering the chair, and that the chair is readily brought t0 and locked in any Instead of connecting the levers eZ by eross-barj`, and 'arm g to the leg-rest or frame z', the connection may be made by links jointed to the lower ends of levers and the` ends of the leg-restbut I prefer the arrangement shown.

i I claim the combination of the stationary base and seat-frame a, tipping back b, jointed arms c, levers cl,`

leg-rest z', spring-rack bar n, and its foot-piece q, Awhen all are arranged to operate together, substantially as shown and described. l

I also claim, in combinationv with the above, the foot-piece 7e, arranged to swing Idown against or up from the arms Z, substantially asishown and'described. TOR-WAM) WINTER:
