PROVISIONAL SPECIFICATION.
An Improved Saddle Support for Velocipedes and like Vehioles.
I, SAMUEL SIDNEY BROMHEAD of '97 Newgate Street, London, Patent Agent,
(a communication from Baptiste Puybourdin of Paris) do hereby declare the
nature of this invention to be as follows:-
This invention is designed to supply an elastic support to the saddle of
velocipedes and like vehicles in order to 'lessen the effect of jar or shock to
the rider.
It consists of a bolt with long head' working inside a tube the top of which is
connected to the saddle. A lug or projecting eye connected to the head of the
bolt slides up and down in a slot in the tube, and regulates the travel of the
bolt. A spiral spring is placed between the top of the bolt-head and the upper
end of the tube..
Another spiral spring works on the 'free end of the bolt, being stayed' at one end
against a flange on the end of the tube, and at the other or lower end against.no
adjustable nut screwed on the lower end of the.bolt. This screw cut on the 'bolt is
of considerable length, in order to allow of the necessary adjustment of 'the nut, by
the height of which the lower spring is compressed to adapt its force to the weight
.of the rider:
In this way an adjustable elastic seat is obtained' and the vibration of the wheels
minimised.
COMPLETE SERCIFICATION.
An Improved Saddle Support for Velooipedes and like Vehioles.
I, SAMUEL SIDNEY BROMHEAD of 97 Newgate Street, London, Patent Agent,
(a communication from Baptiste Puybourdin of Paris) 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 is designed to supply an elastic support to the saddle of
volocipedes aud like vehicles in order to lessen the effect of jar or shock. to
the rider.
.
It consists of a bolt preferably hollow with long head working inside a tube.tlie
top of which tube is connected to the saddle. A lug or projecting eye connected
to the head of the bolt slides up and down in a slot in the tube, and regulates the
travel of the bolt. A apiral spring is placed between the top of the bolt-head and
the upper end of the tube.
Another spiral spring works around the free end of the bolt, being stayed at one
end against a flange ou,the end of the tube, and at the other or lower end against
an adjustable nut.screwed.on the dower end of the bolt. The thread which carries
this nut is of considerable length, in order to allow of the necessary adjustment of
the nut, by the position of which the springs are compressed to adapt their force
to the weight of the rider.

page_text: I will now describe the invention with reference to the accompanying drawings
in which,
Fig. 1 shows a sectional elevation of the bolt and tube and the springs forming
the support.
Fig. 2 shows a front view of the tube H with the slot and lug.
Fig. 3 shows a portion of the fräine of a bicycle to which the support as shown
in Fig. 1 can be attached.
Fig. 4 shows a variation of the arrangement in Fig. 1.
Fig. 5.shows a portion of the tubular frame of a bicycle adapted to receive the
arrangement in Fig. 4.
A is the 'bolt.
B is the lower spring.
C is the upper end of A which slides freely in H.
D is the adjusting out.
E is.a pin or key to secure C in the slots F.
FF are two slots in the tube H.
Gis a stop end at the lower end of H to hold the spring J in position.
His the tube in which A. works.
Jis the upper spring.
¡
T is the tube to which the saddle support is attached..
ee are holes in the tube T to receive the key E.
n, n, are pins or screws to secure the stop G.
i.
As shewn in Figs. 1. 2. 3, H is the saddle-tube in which the hollow head C
connected to the bolt A slides freely.
When fixing the apparatus together the head C is first placed in the tube H,
then the spiral spring J is placed in position, and the stop-end G is inserted in the
end of the tube H. This stop end is fastened by two screws or pins n.
The spiral spring B is then placed around the bolt A and the put D is
screwed on.
=
By means of this nut the spring B is compressed more or less. The compression
of B, also brings pressure on the spring J, which finds itself confined between the
head C and the stop end G. A pin or key E passes through the upper end of C
and through two longitudinal' slots in the tube H.
13:
Before putting the pin E in place, the support is introduced into the saddle
bearer T, which forms part of the frame of the bicycle, and at the moment the
pin E is fastened in the holes e of the tube T, and through the end of the head C.
By means of this arrangement the tube becomes supported by the spring B
which sustains it from below upwards. The spring J on the contrary presses it
from above downwards.
The saddle is thus suspended in equilibrium between these two forces and-by
means of the nut D, a tension proportional to the weight of the rider can be
obtained.
The result is that when jerks occur, the spring B diminishes the shock and the
spring lessens the rebound. The saddle tube H slides upon the head C, which is
fixed, the pin E, by sliding in the slots F permits these movements.
The spring placed between the nut D and the stop G may be in one piece,
or as shewn in Fig. 1, in two pieces, one being shown at a to b, and the other
at c to d.
In the part cto d the two pieces are shown screwed as it were into each other.
When not expanded the interval between the spirals is equal to the diameter of the
steel wire of which they are made; so that, when the spirals are intertwined
as shown at c-d, there is little or no elasticity owing to the wires being in
contact.

In this way any desired stiffness can be given to the springs, and afterwards the
tension can be regulated by the nut D.

page_text: In the arrangement shown in Fig. 4 the bolt A is fixed to the end of tho saddle
tube H which slides in the tube C. The spring. J is supported by the stop Gand
the nut D by means of which one tightens both the springs. In this case it is the
spring J which lessens the effected jerks and the spring B which minimises the
countershock, the saddle being in equilibrium as before explained, the action of
the springs being merely inverted.
Two screws or pins E fixed in the tube H slide in the slots F formed in two sides
of the head C.
The apparatus is caused to enter the tube T, which forms part of the frame of
the bicycle, and a collar fastens the tube C in such a way that the saddle tube H
rises and falls by sliding in the tube C. The screws E slide the length of the
slots F.
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 [
claim is :-
1. A saddle support for velocipedes composed of a hollow bolt with tubular head
which head slides in a vertical tube, said bolt alides in a stop-end fixed at lower
end of the said tube, of a spiral spring lodged in said tube supported by said stop-
end, sustaining thus the weight of the rider and diminishing the effect of shocks;
of another spiral spring surrounding the said rod aud' confined by a nut in such
manner that it is supported beneath the said stop-end, and diminishes the rebound
or countershock of each jerk, the weight being as it were in equilibrium between
the opposing forces of these two regulable springs as herein described and
set forth.
2. The arrangement described in reference to Figs. 4 & 5 which is in principle
the same as the foregoing as herein described and set forth.
Dated this 30th day of September 1895.
