Improvements in Springs for Cycle Saddles.
I, ARTHUR ACKLOM HAWKINS, of Beau Rivage, Stain Hill Park, Hampton, in
the County of Middlesex, Agent, do hereby declare the nature of this invention
which has been communicated to me from abroad by Seldom A. Bailey, of 183,
Broadway, New York, 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 an improved spring for supporting cycle saddles, and
it has for its object to provide a spring the elasticity of which can be varied to
suit the weight or fancy of the rider.
In the accompanying drawing which illustrates this invention:-
Figure 1 is a view in side elevation, and Figure 2 is a view in plan.
In both views similar parts refer to like letters of reference.
The improved spring consists of four essential parts, three of which form the
spring proper, and the other of which forms the means of adjusting its elasticity.
The spring proper consisting of an upper plate A a middle plate B and a lower
plate C. The upper plate A is curved upwards at its rear end and its extremities
are adapted for attachment to the opposite ends of a saddle which may con-
veniently be attained by means of bolts and nuts passing through the holes or
slots a in it. The rear end of the plate A preferably carries a cross piece A¹
so as to give the saddle three points of support.
The upper plate A is fixed at or near its forward end to the front end of the
middle plate B-which is flat throughout its length--by means of rivets b, b, or
their equivalent, or it may under some circumstances be made in one with it.
The lower plate C, which springs from the rear part of the middle plate B and
extends forward under the same, is preferably formed integral with the said
plate B, but it may be made independent thereof and fixed thereto by means of
rivets or their equivalent. This plate C curves away from the underside of the
middle plate B, and then takes a downward dip and terminates in a short length c
which lies parallel with the intermediate plate B. The part c of the lower plate C
is fixed to the seat pillar X by means of any suitable form of clamp bracket D).
It will be seen that as the curved faces of the upper and lower plates are in
contact with the middle plate, the contact of the said plates increases with the
weight on the saddle and thereby stiffening and reinforcing the spring.
To make the spring more rigid i.e. to decrease its elasticity a plate E is clamped
by means of a bolt or screw E¹ to the underside of the middle plate B, the for-
ward end of the said plate being slotted to adapt it to engage with the heads of
the rivets b, b, or their equivalents whereby its parallel movement on the middle
plate B is ensured.
The rear end e of the plate E is chamfered and is curved slightly downwards so
that its upper face does not lie in contact with the under face of the middle
plate B throughout its length, and its chamfered end engages with or rests on the
upper surface of the lower plate C as shown in Figure 1. It will be obvious that
the more the rear end e of the plate E projects into the space between the under-
