Improvements in Saddle Supports for Bioycles.
CHARLES ALBERT CRANE, 31, Warwick Square, S.W., Doctor of Medicine, do
hereby declare the nature of this invention to be as follows: —
To place an elastic or pneumatic buffer in the saddle tube of a bioycle so that
the saddle pin rests upon it. By saddle tube I mean the tube of the bicycle into
which the saddle support is telescoped. By saddle pin I mean that part of the
saddle support which is telescoped into the saddle tube.
The buffer may be made of small pneumatic cylinders of india rubber, of
spherical pneumatic balls, of india rubber rings which may be either solid or
hollow containing air or by other means. The saddle pin may be fitted into a
cylinder the cylinder to be fitted into the saddle tube. The saddle pin to move
freely up and down in the saddle tube and to be allowed to rotate or not. T'he
pin may be made to contain the buffer.

Improvements in Saddle Supports for Bicycles.
1, CHARLES ALBERT CRANE, 31, Warwick Square, London, S.W., Doctor of
Medicine, 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:-
A buffer consisting of a series of rings or discs or balls or cylinders of india
rubber and dises or rings of wood or other suitable material.
The buffer is to be placed beneath the saddle pin and supports it.
The rings are hollow or solid of less diameter than the diameter of the tube
into which they are to be placed.
The balls are either solid or hollow and small enough to pass freely up and
down the tubo when they are compressed.
The discs are to he of a diameter rather less than the diameter of the tube
containing them and they must be not less than half an inch thick and somewhat
biconcave allowing a sufficient flat margin for the rings to rest upon it.
The discs may be perforated in the centre so as to allow of a rod or piece of stick
or cane to pass through the whole length of the buffer being fastened to the bottom
disc to allow of the easy removal of the entire buffer.
The buffer so formed is then to be placed in the saddle tube upon a diaphragm
or partition placed at a convenient distance down the saddle tube.

page_text: A metal washer is placed on the top of the buffer for the saddle pin to rest on.
The buffer instead of being simply placed in the saddle tube as above described
may be placed in a separate tube which fits into the saddle tube. This tube
-Fig. 1 & 2-or sleeve or cylinder is closed at one end by a metal bottom on
which the buffer rests round the other end or top of the sleeve a collar 19
placed to prevent it slipping too far down the saddle tube. The sleeve is kept in
its place by the bolt pussing through the top of the back stays and lug in the same
way as the saddle support is secured in ordinary bicycles. On the collar is a
projection to pass through the slot cut in the back of the saddle pin and to limit
the rotation of saddle the rotation can be graduated by a wider or narrower slot.
The saddle pin is made so as to slide freely up and down in the sleeve and to
rotate, a slot is cut down the back of the saddle pin to receive the projection on the
collar.
The constuction of any buffer bears a resemblance to the vertebral column. The
effect of this buffer is to prevent the concussions caused by the inequalities of the
surface over which the bicycle is propelled from being communicated to the body
of the rider.
The partial rotation of the saddle also contributes to prevent concussion and
saddle soreness.
Complete rotation is not necessary.

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:
1. A buffer composed of a series of elastic and more or less hard materials
arranged alternately adapted to support a bicycle saddle pillar.
2. A rotating saddle support in which the rotation can be graduated.
