Complete Specification Accepted, 24th Aug., 1888
I, FRITZ VOGEL of Mittweida in the Empire of Germany Manufacturer do hereby
declare the nature of this invention to be as follows:-
This invention relates to chairs or seats having adjustable back or back rests and
adjustable foot rest and it consists in a novel manner of rendering the same adjustable
so that the adjustment may be varied by the sitter without rising from or leaving the
chair.
The back is hinged at the rear of the seat and the foot rest to the front of the seat.
The back and the footrest are connected by cords, passing through the arms of the
seat, in such a manner that by depressing the footrest the back is raised and by
depressing the back, the foot rest is raised. At the passage of the cord through the
arm is arranged a friction brake acting automatically or otherwise for securing the
back and foot rest in the position given to them.

page_text: 1 FRITZ VOGEL of Mittweida in the Empire of Germany Manufacturer do hereby
declare the nature of this invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
The invention relates to chairs or seats in which the back or back rest, and the
footrest are adjustable, and it consists in a novel manner of or means for relatively
or mutually supporting said back and foot rests so that they may be adjusted
by the person sitting in the chair without rising from or leaving the same.
Reference being made to the annexed drawings. Fig. represents in side view
a chair fitted the said improvements and adapted to be folded up. Fig. 2 is a front
view thereof. Fig. 3 shows the same folded. Figs. 4 and 5 represent a detail of the
improvements and Fig. 6 illustrates the invention as applied to an arm chair of a
more substantial kind.
The improvements substantially consist in pivoting the back and foot rests to the
standing framework and connecting them together by cords or the like passsing
through a part of the standing frame work, where a suitable brake is applied for
holding the rope or cord, so that when the said brake is loosened the back may be
lowered or raised and the foot rest correspondingly raised or lowered. Thus in
the drawings the letter A is used to designate the seat and generally the standing
part of the frame of the chair, whether the same be adapted to fold or not. B is the
back pivoted or hinged to the frame at c, and D is the foot rest pivoted to the frame or
hinged thereto at d. s is the cord fastened at one end to the back and at the other to
the foot. There may be two such cords one on each side of the chair. The cord s
passes through the brake device g provided in a standing portion f. suitably formed
with the frame of the chair so that the brake occupies a position relative to the parts
of the chair substantially as shown. Thus in a folding chair of the kind shown the
part may be a continuation of one of the pivoted frame bars forming the legs of
the chair, in a fixed chair as shown in Fig. 6 the part may be the fixed arm of the
chair and the brake g be provided in the front end thereof. As a brake may be used
any suitable clamp or the like adapted to be unclosed by a person seated in the
chair, or a friction device may be used as shown in Figs. 4 and 5-being a sinuous
slot in which the cord is subjected to lateral friction according to the longitudinal
strain on the cord. By lifting the feet from the rest D or by pressing less heavily
with the feet thereon the cord is loosened and the back may be pressed down or, by
leaning forward in the seat the foot rest may be depressed and the back raised.
knot or stop may be placed on the cord to prevent the back rest from being lowered
too far.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is ;-
1. In chairs or seats the combination with a hinged back and hinged foot rest, of a
cord or cords or the like connecting same, and a brake device for said cord in the
frame of said chair or seat substantially as set forth.
2. In chairs or seats having movable back rest, movable foot rest and a cord or the
like connecting same; a brake device g, being a sinuous slot, for said cord and a knot
in said cord substantially as and for the purposes set forth.
