PROVISIONAL SPECIFICATION.
An Adjustable and Folding Chair.
ERNEST SMITH Chair Maker of 17 Tankerville Road Streatham Common in the
county of Surrey England do hereby declare the nature of my said invention to be
as follows:-
:-
Bars crossing each other and pivoted together at the point of intersection form the
legs of the chair said bars extending upwards far enough to constitute a support for
a horizontal bar which forms the arm of the chair said arm bar being pivoted to both
legs of the chair so as to brace them apart and keep them in position when the chair
is set up for use. A slot is made horizontally in the arm har so that the pivot attach-
ing the bar to the leg nearest the back of the chair can slide in the slot, theroby
enabling said leg to pass into a position nearly parallel with the front leg when the
chair is folded. The legs and arms thus arranged and constructed for each side of
the chair are joined together by cross rails so as to form a frame work into which the
seat and back of the chair are placed, the front part of the seat resting on a cross rail
of the frame work or on pins projecting from the inner side of the front legs. The
rear end of the seat is pivoted to the lower part of the back and the back is pivoted
to the arms of the chair at a point sufficiently above the seat to cause the back thus
suspended between the arms of the chair and the seat pivoted to the back and having
the front part resting on the cross rail or pins as before described, to be in equilibrium.
Having constructed the chair in the foregoing manner a slight movement of the body
by a person sitting in it will adjust it to any angle required. I claim as my inven-
tion the arrangement and construction of the arm bars as herein described for the
purpose of folding the chair and keeping it in position and also for suspending the
back from the same.

SPECIFICATION.
An Adjustable and Folding Chair.
ERNEST SMITH chair manufacturer of 17 Tankerville road Streatham Common
in the county of Surrey England, do hereby declare the nature of my said invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Fig. 1 in the drawing shews section of chair frame when open. Fig. 2 when
folded.
The bars A B forming the legs of the chair are pivotted together at the point of
intersection n and extend upwards far enough to constitute a support for the hori-
zontal bar C which forms the arm of the chair, to the under side of said arm bar a
metal plate wis securely fastened, to this plate the legs A B are pivoted at the
points a e, the pivot e passes through a slot in the metal plate w and moves along this
slot towards the pivot a in folding until the legs are brought into a position paralle!
to each other as shown in Fig. 2 of the drawing. The bar D is pivoted to the har ()
at f and to the seat bar E at 9. The bar E rests upon a pivot projecting from the
bar A at the point i and slides upon the same, the sloth preventing the seat bar
sliding too far to the back or front and also attaches it to the leg of the chair.
