Improvements in Saddles Suitable for Cycles.
We, CHARLES ARTHUR CHAPMAN, of Glenthorne House, Horley, in the County
of Surrey, ALFRED WARREN, of Aberdeen House, Horley, aforesaid, and CHARLES
FIPPARD, of Brighton House, Horley, aforesaid, do hereby declare the nature of
this invention to be as follows:-
According to this invention the front and back of the saddle are made of shaped
plates. The back U lies in an approximately horizontal plane with its legs point-
ing forwards whilst the front U (which is smaller) lies in an approximately vertical
plane with its legs pointing downwards. These U shaped plates are connected by
stretched springs, preferably in the form of india rubber threads above which is
a piece of soft leather or the like to form the seat and their middles are also con-
nected and supported by a curved bar having one or more knuckle jointed hinges
in it so arranged that the ends cannot be turned upwards beyond a certain point by
the tension of the springs but can be turned downwards by pressure so further
stretching the springs.

Improvements in Saddles Suitable for Cycles.
We, CHARLES ARTHUR CHAPMAN, of Glenthorne House, Horley, in the County
of Surrey, ALFRED WARREN, of Aberdeen House, Horley, aforesaid, and CHARLES
FIPPARD, of Brighton House, Horley, aforesaid, 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 spring seats especially suitable for the saddles of cycles.
The saddle consists of front and back plates connected by springs which form
the seat each plate being supported by a curved bar having one or more knuckle
jointed hinges in it so arranged that the ends cannot be turned upwards beyond
a certain point by the tension of the springs but can be turned downwards by
pressure so further stretching the springs.

page_text: Figure 1 is a vertical central section, Figure 2 is a plan, and Figures 3 and 4
are transverse sections on the lines 3-3 and 4-4 Figures 1 and 2 looking to the
left and right respectively. Figure 5 is a local section on the line 5-5 Figure 1.
a and b are the back and front plates (the latter being constructed in the form
of an inverted U) carried by arms a¹ and 6¹ fixed to them and pivotted respectively
at ab to the flanges c¹ c¹ of the plate c.. The four corners of each flange c¹ are
turned outwards forming stops 2 which limit the movement of the arms a¹ and b¹.
The plate rests on a plate & the flanges d¹ of which are notched and rest on the
usual bar support e the whole being secured by the eye f and nut f¹. g is an india-
rubber cord covered with braiding and laced round pulleys h on the plates a and b.
The peak is covered with leather ; and the seat may also be covered with soft
leather or other material.
The details of the arrangement may be varied for example the indiarubber
may be replaced by a helical spring or springs of metal, the arm a¹ may be fixed
to the frame and so on.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we wish it to be understood
that we do not claim broadly a saddle having a seat consisting of stretched springs,
but we declare that what we claim is :-
1. Mounting the front and back plates so that they can separate by extending.
the springs.
2. In arrangements such as are referred to in Claim 1:-
a-making the front plate in the form of an inverted U.
b-pivotting the supports of the front and back plates and providing stops
to limit their travel.
c-making the seat of an indiarubber cord laced round pulleys on the front
and back plates.
3. Seats substantially as described and shown in the drawings.
