ROBERT ROBERTS JARDINE Clerk to H.M. Office of Works, Birmingham
Oughton Place Sparkbrook Birmingham do hereby declare the nature of this
invention to be as follows:-
The pneumatic seats are made up of (a) wooden frames or seats which can be
made to any size & to any shape: (b) india rubber bladders which also can be made
to any size & to any shape, with or without holes in centre but in all cases supplied
with necks and valves which are placed in the most convenient position for purposes
of inflation or deflation: (c) india rubber solution: (d) sheet india rubber:
(e) volute which is a canvas material which has undergone a process of vulcanizing
(f) rims of wood & (g) canvas or like material for first covering.
The above articles are put together as follows:-
A thin coat of solution is placed on the top side of wooden seat or frame, and the
under side of india rubber bladder, after which they are firmly fixed together and
then inflated.
Another coat of solution is placed along edges of frame or seat, & of the india
rubber bladder, also upon strips of volute, after which the volute is put round the
elges of the frame and bladder & prevent the latter from coming away from the
former when any pressure is put upon the seat.
Bladders with holes in the centre have a sheet of india rubber-perforated or
otherwise stretched across the hole.
Rims of wood of suitable dimensions are fixed to the sides of the seat, or under-
ueath, to which the covering is secured, so that the covering can be removed, if
A sheet of canvas
necessary, without interfering with the pneumatic part of seat.
or like material is next placed over the pneumatic seat & secured to rim, to take
the pressure on the seat, and another suitable covering being placed over it,
completes my invention.
The wooden seats or frames having holes in the centre have perforated panels of
wood, placed on the under side of the frames or seats, if necessary, to give extra
security to the pneumatic seat when abnormal weights are put upon it.
Dated this 30th day of November 1894.

ROBERT ROBERTS JARDINE 43 Oughton Place, Sparkbrook Birmingham,
Assistant to Surveyor at H.M. Office of Works, Birmingham, 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 pueumatic seats are made up of I. wooden frames or seats which can be made

page_text: to any size and to any shape. II. india rubber bladders which also can be made to
any size or to any shape, with or without holes. Some seats have to be buttoned
therefore holes have to be made in the bladders, other seats are plain & do not
require holes but in all cases supplied with necks and valves which are placed in
the most convenient position for the purposes of inflation and deflation.
III. india
rubber solution. IV. sheet india rubber. V. volute. Volute is a rubbered canvas.
VI. rims of wood and VII. canvas or like material for a first cover.
These articles are put together as follows:-A thin coat of solution is placed
upon the top side of wooden seat or frame C, and on the under side of india rubber
bladder D, after which they are united, and the india rubber bladder is gently
inflated. Solution is then put upon the edge of india rubber bladder E and edge
of wooden seat F, also on one side of strip of volute-which volute G is sufficiently
long to go all round the seat and of a sufficient width to cover edge of wooden seat
and extend two or three inches up side of india rubber bladder. This being done
the strip is made to adhere to the edge of wooden frame and india rubber bladder.
H represents valve.
A rim of wood K of suitable dimensions, is next put on the bottom side of
wooden frame. A. cover of canvas or like material I is next placed over the
india rubber bladder and fixed to the edge of the rim, after which the seat is made
complete by putting on a second cover J of suitable material which cover is also
secured to the rim.
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. The application, to chairs, seats, couches & the like, of india rubber bladders
cemented on one side of wooden base, supplied with a valve for the purposes of
inflation & deflation which inflated bladders take the place of the ordinary or usual
stuffing substantially as described and illustrated.
Dated this 22nd day of August 1895.
