Improvements in connection with Upholstery.
I, CHRISTOPHER WILLIAM BRAITHWAITE, of 84, Brayard Road, Peckham, in
the County of Surrey, Boot Manufacturer, do hereby declare the nature of this
invention to be as follows:
My object is to provide all articles of furniture usually upholstered or that may
be used to sleep or rest on, with a pneumatic seat or seats, so constructed that the
use of hair or other materials hereto used in stuffing them, also all springs and
other appliances for the object of resilience will be obviated.
For this purpose chairs of every description, sofas, couches and all other articles
of upholstery will be provided with a seat or covering preferably constructed of
pure or vulcanized rubber or other suitable material, shaped as may be desired,
filled with air or gas, hermetically sealed or having an aperture at some convenient
place, through which extends a valve or valves communicating with the interior
of the seat or seats, the said valve or valves being so arranged as not to constitute
unsightly projections. A suitable pump will be used to inflate the pneumatic
seat or seats.
The bottom and sides of my improved pneumatic seat or seats may be lined in
the interior with a wooden frame made to the desired shape or they and the top
covered with strong canvas or other material and the whole with plain or
ornamental leather, pegamoid or any of the materials usually employed in
upholstering.

the County of Surrey, Boot 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: -
This invention consists of a pneumatic seat or seats so constructed and arranged
that the use of hair or other materials heretofore used in stuffing or filling them,
also all springs and other appliances adopted for the purpose of resilience will, by
this invention be obviated.
For this purpose, chairs of every description, sofas, couches, beds and all other
articles of upholstery will be provided with a seat or seats or covering in one or
several parts, sections, divisions or chambers, and these will be, preferably, con-

may be required or desired. These parts,, sections, divisions or chambers will be
inflated with air or gas,, hermetically sealed, or having an aperture, opening or
passage at some convenient place or places, through which extends a valve or
valves, these being arranged in such a manner as not to constitute unsightly
projections. A suitable pump will be used for the purpose of inflating the seat
or seats or coverings. The arm and back or head rests of chairs, sofas, seats or
other articles usually upholstered will be provided with a suitable pneumatic
cushion or cushions, pad or pads, these may be divided into one or more compart-
ments, constructed of rubber or other suitable material, hermetically sealed or
fitted with a valve or valves by which the cushion or cushions can be inflated as
and when required, by means of a suitable pump.
The bottoms and sides of my improved pneumatic seat or seats or coverings may
be lined exteriorly or interiorly with a frame constructed of wood or other suit-
able material fashioned to the desired or required shape or shapes.
and
or
The interior exterior of the sides, top or tops of the seat or seats, and the
whole of the arm and back or head rests may be lined or covered with strong
canvas, non-puncturable or other suitable material and this, also the wooden
portion, finally, with plain or ornamental leather, pegamoid or any of the
materials usually employed in upholstering.
In order that my invention may be readily understood I will, now, proceed to
describe the same fully with reference to the accompanying drawings, wherein
Figure 1 represents section of a chair fitted with my improved pneumatic
seat also cushions or pads constituting arm and back or head rests.
Figure 2 represents section of a sofa or couch, fitted with my improved pneu-
matic seat, shewing the air chambers constructed in three compartments.
Like letters indicate like parts throughout the drawings.
Figure 1. A is the air chamber B. the wooden frame C. the aperture with
valve. D. the arm and back or head rests.
Figure 2. A. is the air chamber constructed in three compartments, B. the
wooden frame, C. the apertures with valves.
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. A pneumatic seat or seats preferably constructed of rubber or other material,
covered with non-puncturable, or other suitable material filled with air or gas
hermetically sealed or capable of being inflated by means of a valve or valves,
to which a small air pump can be applied as and when required.
2. A pneumatic cushion or cushions, pad or pads, constituting the arm and
back or head rests of chairs, sofas, or seats of any and every description. These
may be divided into one or more compartments or divisions, preferably constructed
of rubber or other material, covered with non-puncturable or other suitable
material, filled with air or gas, hermetically sealed or capable of being inflated
by means of a valve or valves, to which a small air pump can be applied as and
when required.
