I, FREDERICK WILLIAM ROE, of Stonehenge, Tasmania, Gentleman, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in pneumatic cushions for bicycle seats
and has for its object to construct a simple, effective and cheap device for this
purpose. The cushion consists of a circular air chamber with valve, inclosed in a
cover of cloth or leather or the like. The whole forming a circular seat about nine
inches wide by two inches thick when blown up, having a hole in the centre and a
strap for attaching it firmly to saddles in ordinary use on bicycles, by passing the
strap over the front and through the saddle underneath returning through the
centre and fastening over the back thereby depressing a narrow strip of the cushion.
in front and behind.
Improvements in Pneumatic CusшIONS FO
I, FREDERICK WILLIAM ROE, of Stonehenge, Tasmania, Gentleman, do hereby
the same is to be
declare the nature of this invention and in what manner
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in pneumatic cushions for cycle seats and
has for its object to construct a simple, effective and cheap device which may be
readily attached to existing saddles and which shall give to the seat all the
advantages to be obtained by using pneumatic or divided saddles.
The cushion consists of an air chamber of rubber which chamber may be
constructed in the same manner as the inflation tubes provided in pneumatic tyres
The
and has a pump attachment provided with a valve of any well known form.
chamber is enclosed within a cover of cloth leather or any other suitable material
and is approximately circular in outline, although the form may be varied to suit
circumstances, and having a central opening through which is passed a strap or
straps securing the same to the seat, the strap passing over the front through the
saddle underneath returning through the centre and fastening at the back by a
buckle or other device attached to the end of the strap.
In order that the invention may be the better understood drawings are appended
in which Fig. 1 is a plan of the leather of a cycle saddle showing the invention
lied thereto

page_text: Fig. 2 is a transverse section on line A B Fig. 1.
In Fig. 1 is shown the pneumatic seat or, cushion which consists of an inner air
tube A provided with a pump connection B indicated by dotted lines Fig. 1 which
is carried through an opening formed in the cover C which may consist of cloth or
any suitable material and which as shown. is sewn round the outer edge at D
and is open upon the inside where holes E are provided to receive a lace F. The
seat or cushion which may be circular in outline but is preferably of
the configuration shown in the drawings, is secured to the saddle G by means of the
strap H one part of which as shown in the drawings is passed over the front of
the seat, then through the opening in the centre and through the central opening I
underneath the saddle leather over the back of the seat, and is secured at the end
to the other end of the strap by a buckle or suitable device. A slit J is cut in the
front or beak of the saddle leather through which the strap H is passed and lead
upon the underside of the saddle G. up through the opening: I and over the back of
the seat where it is secured as aforesaid. When strapped tightly the seat or
cushion presents, at the points where compressed by the strap, the appearance
shown in the sectional view. Fig. 2 leaving a free passage for the air between the
riders person and the seat and at the same time preventing injurious pressure at
those points: A strip of cloth or the like attached at both ends to the cover C
of the cushion and upon the underside thereof is provided to receive the
pump connection.
When it is desired for any purpose to remove the inner tube A, the strap H is
first freed from the buckle at the back end when the ends of the same may be
drawn through the opening I and either thrown back or entirely withdrawn, leaving
the seat free for removal. The lace F is next withdrawn from the holes E when
the cover C may be opened out and the tube A withdrawn if required.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is.
The improved pneumatic cushion for use upon the saddles or seats" of cycles,
and the means of and method employed for attaching the same to the said
seat, substantially as herein set forth and as shown by the accompanying
drawings.
