Improvements in or connected with Spring Saddles for Velocipedes
or other Road Vehicles.
I, EDWIN PERCIVAL ALLAM of 14 Hatton Garden, in the County of London,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to obtain greater resilience in the saddle and to
construct the spring devices in a compact form. To this end I employ helical
springs; one of these springs is attached to one end of frame of the leather seat,
(hereafter referred to as the saddle) the other end of the spring rests on the exterior
flange of a cylinder which is encompassed by the spring and which is open at the
end formed with the flange, but closed at the other end; the length of the cylinder
is less than the spring to allow room for the compression of the latter. Inside the
cylinder I place the second helical spring, one end of which is attached to the bar
or bars to which the clip is attached, the other end presses against the closed end of
the cylinder. This spring is also longer than the cylinder, allowing room for the
compression of the spring. Sometimes I attach the inner spring to the saddle and
the outer spring to the bar or bars. One of these improved compound springs and
cylinder is usually placed under the front end of the saddle, and two at the back,
but sometimes only one is placed at the back, and sometimes an ordinary helical or
bent spring is placed at the back, and my improved springs at the front or vice versa.
To keep the leather seat of the saddle stretched I may arrange that the direction of
the springs, especially when used at back and front, shall be at a greater angle
than 90 degrees with each other. For the same purpose I attach the front of the
saddle to the upper spring by means of a connection adjustable in the direction of
the length of the saddle. The saddle can also be kept stretched by independent
adjustable bars or wires. Sometimes I attach a disc to the spring inside the cylinder
thus forming a piston inside the cylinder, this acts as a dash pot, and tends to damp
any sudden motion of the springs.
Sometimes I dispense with the cylinder and connect the two springs together
at their lower ends and attach the top of the inner spring to the bar by means
of a short metal rod. In some cases instead of employing two springs I form the
outside and inside convolutions out of one piece of wire.

COMPLETE SPECIFICATION.
Improvements in or connected with Spring Saddles for Velocipedes
or other Road Vehicles.
I, EDWIN PERCIVAL ALLAM of 14 Hatton Garden, in the County of London,
Electrical Engineer, 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 :-
The object of this invention is to obtain greater resilience in the saddle and to
construct the spring devices in a compact form.

page_text: In order that my invention may be readily understood I will describe same with
reference to the accompanying drawings whereon
Fig. 1 shews spring devices according to my invention, applied to a velocipede
saddle, the latter being shewn in vertical section.
Fig. 2 is a horizontal section of one of the spring devices taken on the line X Y
of Fig. 1.
Fig. 3 is an elevation of a part employed in the construction, and
Fig. 4 is a vertical sectional elevation shewing a modified arrangement.
Referring to the helical spring arrangement shewn in the peak of the saddle
Fig. 1, I attach one end of a spring A to one end of the tension frame B of the
saddle leather, C, the said end of the frame B in the example shewn being composed
of a block C through which a tension screw C freely passes, (not being tapped
therein) and the screw has a nut thereon to bear against the block C and force
outwards the fixing C3 of the saddle leather C.
The helical spring at its lower end rests on the exterior flange D' of a cylinder D
which is encompassed by the spring A as at Fig. 2, and which is open at the end
formed with the flange D', Fig. 1, but closed at the other end; the length of the
cylinder is less than the spring A to allow room for the compression of the latter.
Inside the cylinder D I place a second helical spring E, one end E of which is
attached to the bar, bars or frame F to which the clip or fixing is attached by which
the frame F is secured to the seat pillar. The other end of the spring E presses
against the closed end of the cylinder D and this spring E is also longer than the
cylinder D allowing room for the compression of the said spring.
In some cases I may invert the spring device just described, and then attach the
end E¹ of the inner spring E to the saddle frame at (, and fix the end of the outer
spring A to the bars or frame F.
One of these improved compound springs and cylinder, is usually placed under
the front end of the saddle, and two at the back, but sometimes an ordinary helical
or bent spring or springs may be placed at the back, and my improved spring device
at the front or re versa.
The cylinder D need not necessarily be formed with solid walls, or a solid top, but
may in fact consist of a mere framework, such as for example is shewn at Fig. 3.
Sometimes I dispense with the cylinder D and employ two springs one within
another, and a convenient construction of such arrangement is shewn at Fig. 1 at the
rear end of the saddle, where the internal spring E is formed from the same piece of
wire as is the external spring A. In this case the top of the internal spring E is
carried from the frame F by a rod H while the upper end of the external spring A
carries the saddle.
It is obvious that this arrangement of springs and connections might be inverted
if desired.
Sometimes as at Fig. 4 I attach a disc J to the spring E inside the cylinder D
thus forming a piston inside the cylinder, this acts as a dash pot, and tends to damp
any sudden motion of the springs.
my invention I am enabled within a given height to obtain a greater
increased length of spring, thus giving greater flexibility, resilience, and consequent
comfort to the rider, all of which arrangements are especially useful in saddles
for ladies.
I would have it understood that my improved spring devices can be applied to any
construction of saddle or seat, and I do not limit' myself to any particular construction
of such saddles, or tension devices, fixings or other parts thereof, but
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim as my improved spring devices for velocipede saddles and seats, to be interposed
between the saddle leather or seat proper, or its framework, and the carrying bars or
frame, is as follows:-
1. The spring device composed of an outer helical spring, fixed at one end to one

page_text: of the parts to be distanced, or insulated from vibration, encompassing a vertical
cylinder, and resting upon a flange at the lower open end of same, in combination
with an inner helical spring, one end of which extends within the cylinder, abutting
against the top thereof, while the other end of the inner spring is attached to the
other part to be distanced, substantially as described.
2. The spring device composed of an outer helical spring fixed at one end to one
of the parts to be distanced or insulated from vibration, the other end being
returned and fixed to or formed into a helical spring extending in the interior of the
outer spring, the terminal end of the inner spring being fixed to the other part to be
distanced, substantially as described.
3. The arrangement of disc within the cylinder, in combination with the helical
springs, substantially as and for the purposes described and illustrated with reference
to Fig. 4 of the accompanying drawings.
4. The combination and construction of parts composing my improvements in, or
connected with, spring saddles for velocipedes or other road vehicles, all arranged and
acting, substantially as and for the purposes described and illustrated with reference
to the accompanying drawings.
