Inventor, do hereby declare the nature of this invention to be as follows:-
The materials required are as follows. 1st. Narrow wood frames, having a metal
casement on the inside & underneath of frame. 2nd. Sheet india-rubber. 3rd. India-
rubber solution. 4th. Air proof cushion, made of air proof cloth, or india-rubber, or
part of one & part of the other. 5th. Stout canvas, light leather, or such like
material. 6th Suitable covering, which articles are put together in the following
manner :-A piece of sheet india-rubber is secured by means of india-rubber
solution to & over the whole surface of the frame. This piece of sheet india rubber
is then divided in the centre forming an aperture, through which the air cushion
may be extracted or replaced. The edges of this aperture inay be strengthened by
a narrow strip of air proof cloth, being secured by means of india-rubber solution.
India-rubber solution is used in the following manner :-Both parts that require
adhering to be given a thin layer of the solution, & afterwards exposed to the air
for about thirty minutes, after which they will firmly adhere when brought
together. The air proof cushion which may be made of air proof cloth or india-
rubber, must have a hole in the centre of cushion, which assists ventilation, & may
be made with a tube running through cushion, from the front to the centre hole,
(this also assists ventilation).
The air cushion must be made the exact shape of frame, but may be made from
half an inch to one & a half inches larger, according to the amount of inflation
required. The air cushion is then slightly inflated, & placed upon the top of sheet
india-rubber covering frame. Then a piece of stout canvas, light leather or such
like material is tacked all round to the outside edge of frame forming a strong
collar around the air cushion.
The air cushion is supplied with neck & valve as a means of inflation or deflation.
The sheet india rubber covering frame, carries the air cushion & acts as a spring
when weight is brought to bear upon it. The seat is then covered with any
suitable material in the following manner. The top of covering is cut out the
exact shape of seat, then a narrow strip of the same material (varying in width
according to the amount of inflation required) is then sewn to the edge of the top
of covering. The covering is made the wrong side & then turned. The covering
may have a piece of india-rubber insertion in the centre, & in the front of covering
opposite tube. (This piece of insertion is perforated as a means of ventilation.)
India-rubber insertion is a non-elastic material, being a kind of canvas placed
between two pieces of india-rubber.
The following are some of the advantages-Cleanliness, comfort, ease, coolness &c.

Improved Pneumatic Cycle Seat and Saddle.
We JOSEPH ARTHUR BONDS of 39 Stanbury Road Queen's Road Peckham
London, S.E. Surveyor, LIZZIE DAWES of 34 Ivanhoe Road Camberwell London
S.E. Lady and SAMUEL DAWES of 34 Ivanhoe Road Camberwell London, S.E.
Inventor, 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 improvements in pneumatic cycle seats and saddles.
The materials required are as follows. 1st. Narrow wood frames, (made the exact
shape as required) having a light metal casement on the inside & underside of
them, & the metal casement secured to the narrow wood frame by screws or light
nuts & bolts. 2nd. Sheet india-rubber, or other elastic material. 3rd. India-
rubber solution. 4th. Air proof cushion, made of air proof cloth, india-rubber, or
one side of cushion may be made of air proof cloth & the other of india-rubber.
5th. Stout canvas, light leather (must be free from grease) or other suitable material.
6th. Suitable coverings. Which articles are put together in the following manner.
A piece of sheet india-rubber the same size & shape of narrow wood frame, is
secured by means of india-rubber solution to & over the whole surface of frame.
This piece of sheet india-rubber is then divided in the centre forming an aperture
sufficiently large that the air cushion may be extracted or replaced in case of
puncture. The edges of this aperture may be strengthened by a narrow strip
of air proof cloth, or other suitable material, being secured to them by means of
india-rubber solution. This aperture may then be laced together after the manner
of a football covering. India-rubber solution is used in the following manner.
Both parts that require adhering to be given a thin layer of the solution, & after
exposure to the atmosphere for about 30 minutes they will firmly adhere when
brought together. The air proof cushion must be made the same shape as the
wood frame, but may be made from half (t) an inch to one & a half (1) inches
larger according to the amount of inflation required. The air proof cushion must
have a hole in the centre which allows of free ventilation, also giving the exactness
& evenness of inflation required. The air cushion must be supplied with valve, the
usual means of inflation or deflation. The air cushion also may be made with a
tube running from the front (or peak) of saddle, to the hole in the centre, or the
cushion may be divided from the front (or peak) to the centre hole, (that means
that the cushion may be made in two parts from the front (or peak) to the centre
hole instead of one part,) & a loose india-rubber tube inserted, which will also
assist in ventilating the saddle or seat, or the seat or saddle may be made without
either.
The air cushion is then slightly inflated & placed upon the top of sheet india-
rubber covering frame. Then a strip of stout canvas, light leather, or other
suitable material is secured by tacking or otherwise, all round the wood frame to
the outside edge of it, forming a strong collar around the air cushion, (which forms
the interior of seat). This sheet india-rubber covering narrow wood frame & which
carries the air cushion, acts as a spring when weight is brought to bear upon the
seat. The sheet india-rubber that has been found most suitable are the thicknesses
known as one thirty second (32) or one sixteenth (1) of an inch. The seat is then
covered with any suitable coverings, the first or inner covering may be made of
ordinary canvas, & the coverings may be made in the following manner. The top
of covering is cut out the exact shape of seat, then a narrow strip of the same
material (varying in width according to the amount of inflation required) is sewn
to the edge of top of covering, & to hide all stitching may be made the wrong side

page_text: f material & turned. The final or outer covering may be made in the manner
escribed. The coverings (if suitable) may have a piece of india-rubber insertion
the centre of covers, which may be perforated to allow of further ventilation.
In order that our invention may be thoroughly understood we annex drawings.

metal casement (which carries the narrow wood frame) & sheet india-rubber
ttached to wood frame.

Fig. 3 is a section on line C. D. of Fig. 1 showing all that is in Fig. 2 with the
addition of M which shows valve the means of inflation & deflation, also J the
whole of inserted tube.
Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed, we declare that what we
claim is.
The mode or means of making pneumatic cycle seats & saddles, first by carrying
an inflated cushion upon a piece of sheet india-rubber, (or other elastic material)
secured to a narrow frame, second the air cushion kept in place by a collar
attached to the outside edge of frame substantially as described & illustrated.
