COMPLETE SPECIFICATION.
Inflated Cushions or Pads.
WILLIAM ARTHUR STANFIELD 134 Grosvernor Road Belfast Clerk, 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 relates to cushions or pads, inflated with air and which are to
consist of an air tube or chamber, valve, frame and cover.
Such cushions may be applied instead of hair, flock &c. which are in common use
as seats, lounges, beds, crutches, saddles, harness and other purposes. Air chamber
may consist of rubber or other suitable material, having valve affixed or attached
for the purpose of inflation. Valve may be any suitable design. Cover may be
any material capable of withstanding the pressure of inflation, having pockets in
its edges, into which wire or other substance is inserted, or the edges may be
thickened, strengthened or reinforced to withstand the tension caused by inflation,
when it is attached or fastened by its edges.
I attain my object in the manner illustrated by the accompanying drawings in
which
Figs. 1 & 2 are views in longitudinal section of a crutch head, embodying my
invention.
Fig. 3 is a diagrammatic view of wire edges, shewing joints & hinges.
I form a groove or recess underneath the edges of frame A into which the wire
edges of cover B are inserted. In order to provide for the adjustment of wire, I
form it of two or more parts, the engaging end of one part C as a socket, and the
CD 011

page_text: engaging end of the other part D as a tongue. It may also have one or more
hinges E formed in it lengthwise, for the purpose of contracting the wire, to
facilitate the placing or removal of cover, when the grooves or recesses are situated
inside the frame as shewn in Fig. 2.
As a modification of above the cover may be stuck on, or fastened with nails,
hooks, or laced in such a manner that it will confine the air chamber.
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 :-
First. The method of affixing inflated cushions to frames substantially as set
forth.
Second. The use of covers having wire inserted in its edges, or any mere
modification of same, or having its edges otherwise thickened, strengthened or
reinforced, to withstand the tension caused by the pressure of inflation.
Third. The combination of parts respectively used in making inflated pads and
-cushions viz. an air chamber, valve and cover as described, with a frame of any
suitable shape, all combined, arranged and operating as, and for the purpose
.set forth.
