RECLININ'G-CHAIR; No.1.73,974. .Patente d Feb. 22,1876.
JETERSv PHOTO-HTHOGRAPNER. WASHINGTON, Dv C.
UNITED STATES PATENT QFFIGE- JOHN LEMMAN, OF CINCINNATI, OHIO.
IMPROVEMENT IN RECLINING-CHAIRS.
Specification forming part of Letters Patent No. 173,974, dated February 22, 1876; application filed January 15, 1876.
To all whom it may concern: I
Be it known that I, JOHN LEMMAN, of Gincinnati, Hamilton county and State of Ohio, have invented an Improvement in Reclining- Chairs, of which the following is a specification:
My invention relates to the class of chairs in which flat springs are introduced between the seat and stand; and my invention consists in making the upper surface of the stand of a combination of straight and curved surfaces, and attaching thereto straight flat position in which it is at rest or occupied by a sitter, seated in an advanced position on the seat. Fig. 2 is a side View of the same when swung back and hearing such a weight as would cause the springs to rest on the stand the entire length. Fig. 3 is a perspective View, showing the way the springs are attachcd.
A is the seat, B B are the springs, and O the stand. The springs B, when fastened to the stand, as shown, extend horizontally, as shown in Fig. 3, and the chair-seat as it leans back is supported on these springs elastically and retained by them in proper position on the curved ways of the stand. The springs are secured at their outer ends to the bottom of the seat, by screws or otherwise. The top Ways of the stand 0, on which the springs B rest, have a peculiar formation, which is unlike the ordinary rocker-stand. It has from the point X to point Y a horizontal surface, on which the sitter, when desiring anunyielding seat, may solidly rest, and it has from point Y to point Z a curved surface, over which the sitter may, when leaning or sitting back, swing flexibly or elastically. This form of stand enables the convenient use of the chair at a table in writing or otherwise, and gives perfect freedom when desiring to swing back.
I claim The combination of the seat, the flat springs,
and the stand, the upper surface of which has the partly-flat or horizontal and partly-curved
