IMPROVEMENT IN FOOT-RESTS FOR EASY-CHAIRS.
Specification forming part of Letters Patent No. 161,887, dated April 13,1875; application led August 3, 1874.
To all whom it may concer-n Be it known that I, PETER L. LAMBERT, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Easy-Chairs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings making partof this specification, in which- Figure 1 is a perspective view of an easychair, with my improvement applied thereto and raised in a position ready for use. Fig. 2 is a view of the same with my improvement swung down and slid under the seat ofthe chair; Fig. 3, detail in section. 4
My present invention has special reference to a leg-rest for easy-chairs, and consists in a horizontal rest pivoted by links to the frame, which slides under the seat oi' the chair, the said rest being readily swung' up into an elevated horizontal position to support the legs throughout their length, from the thigh to the foot, and being also adjustable to accommodate the stature and suit the ease ofthe occupant.
To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.
In the said drawings, A is the back, B B the arm-rests, and D the frame, ot' the seat ot' an easy-chair. The front a of the frame otl the seat is provided with a longitudinal slot, b, for the reception of a trame, c, the rear ends of which are provided with bent metallic clasps dal, which extend over and under a pair oi' parallel crosspieces, E E, running between the front and back of the frame of the seat. To the front of the fra-lne cis secured a strip, e, in imitation of a panel, and this strip is provided with a knob or handle, h, by which the frame c may be readily drawn out when desired, the metallic clasps d d serving to guide the frame c as it is moved out and in. fi is also a frame of rectangular form to be upholstered; this frame being pivoted at k, by four links, l l, to the frame c, so that when swung down into the position seen in Fig. 2 it may tit therein, and be slid with it under the seat ot' the chair. The frame t', when elevated into the position seen in Fig. 1, serves as a rest for the legs ot' the occupant ot' the chair, the entire leg from the thigh down to the foot being thereby supported in a natural and comfortable position.
The. height of the rest i may be varied to suit the inclination or stature of the incumbent in the following manner: Vhen a short person occupies the chair the rest i, at'ter being raised to the desired height, is held in this position by sliding in the trame c until the rear links l Z are brought against the top of the front of the frame of the seat, which thus supports itas required. When a person ot considerable height is seated in the chair, the frame cis drawn out to its full length, and the leg-rest raised and simultaneously advanced till the front links l Z come in Contact with the inside of the front cross-bar m of the frame c, which thus supports it; the leg-rest in this position being drawn out to its greatest extent.
The above-described improvement maybe readily adjusted and operated, and can be applied to any easy-chair at a tritling cost.
Vhat I claim as my invention- The combination, with the sliding frame c, adapted to be moved Within a chair-seat, ot' the rest i and links l l, whereby the said rest may be raised and held in a horizontal position, substantially as and for the purpose set forth.
Witness my hand this 29th day of July, 1874.
