Improvements in and relating to Cycle Saddles or Seats.
GEORGE CRESWELL BOND, Newcastle Chambers, Nottingham, Mining Engineer,
and FREDERICK SADLER, 4, Hanway Street, London, W., Mechanic, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to improvements in and relating to cycle saddles
or seats and our invention consists in supporting the saddle or seat of a cyclo
by means of preferably two springs of suitable form and affixed to the outside of
the frame or tubes of the cycle.
Wo prefer said springs to be tied or braced together at the top by a suitable
bridge piece or equivalent on which the seat pillar may rest, said pillar being
guided in any suitable manner if required.

Improvements in and relating to Cycle Saddles or Seats.
We, GEORGE CRESWELL BOND, of Newcastle Chambers, Nottingham, Mining
Engineer, and FREDERICK SADLER, late of 4, Hanway Street, London, W., but now
of 15, Grays Inn Road, London, W.C., Mechanic, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
-
This invention has reference to improvements in and relating to cycle saddles
or seats and the object of the said invention is to prevent or to reduce to a
minimum the communication of vibration from the cycle to the rider when
seated on such saddle.
For this purpose we employ a pillar upon which we attach the saddle and rest
the same upon a spring or springs fixed externally to the frame of the cycle the
said pillar being so supported and guided that its movement may be vertical
or practically vertical and consequently in the same direction as that in which
the pressure due to the weight of the rider is exerted.
In order that this invention may be readily understood we have shewn one
form thereof in which two springs are used in side elevation in Fig. 1 of the
accompanying drawings, Fig. 2 being a rear elevation thereof, in each case a
suflicient portion only of the cycle frame being shewn. Figs. 3, 4 and 5 shew
details hereinafter more particularly referred to.
In carrying out this invention we employ a saddle or seat pillar A,-adapted
to carry a saddle or seat in the usual manner which pillar passes through a
vertical or practically vertical socket or equivalent B with which we form or
provide the cycle frame C.

page_text: The two springs D which we employ-preferably ordinary elliptical springs
As commonly used in carriages are placed one on each side of the frome C
in about the position shewn in Fig. 2.
The uppermost and lowermost parts of the two springs D are respectively
connected together by suitable plates or equivalents E shewn in plan view in
Fig. 3 and end elevation in Fig. 4. Each of said plates E is formed with an
aperture e through which the pillar A passes the said plates E thus serving to
guide the lower end of said pillar and in order that the weight of the rider may
rest upon the springs D we provide a clamp F-shown in plan view in Fig. 5-
which clamp we attach in any suitable manner to the upper one of the two
plates the arrangement being such that after having adjusted the sent to its
required height-by sliding the pillar A up or down as may be necessary--we
tighten the clamp up so as to cause it to firmly grip the pillar A and thereby
ensure that the whole weight of the pillar seat and rider rest on the springs D.
The springs themselves are supported by a girder or equivalent G which is
fixed in any suitable manner to the frame C and in order to further keep the
springa Din position without interfering with their elasticity we connect them
together at their ends by means of tie rods or equivalents d.
By arranging the pillar on its spring so that the former when moving under
the weight of the rider has a practically vertical motion friction is reduced to a
minimum whereas, if the pillar is arranged to slide in one of the inclined tubes
of the frame as has previously been done, the weight of the rider does not act
along the pillar but more or less at an angle with it so that the friction of the
pillar on the side of the tube is considerable. In my invention the action or
movement of the pillar relatively to the frame is q te free and unobstructed
and the spring action absorbs the whole or nearly th whole of the vibration of
the machine.
.
It is advantageous to employ two springs-one on ach side of the frame-
ns thereby the action or movement of the various pa is well balanced. The
form of springs shown in the drawings is also most mitable to the intended
purpose as such springs may be made sufficiently delicate having regard to tho
weight of the rider to answer to the slightest vibration and yet strong enough to
keep the amount of compression or movement within reasonable limits.
We do not confine ourselves to the particular form of our invention described
and shewn in the drawings. It is obvious for example that the springs may be
otherwise fixed to the frame and that the pillar may be otherwise attached to
the springs, and that the form or number of springs may be varied.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
-
1. In cycle saddle attachments, supporting the pillar, to which the saddle is
attached, in a vertical or nearly vertical position, on a spring or springs or their
equivalent, substantially as described.
2. In cycle saddle attachments, the combination with the cycle frame of a
saddle pillar capable of sliding in a vertical or nearly vertical direction, and a
spring or springs supported on the cycle frame and carrying the said pillar sub-
stantially as described.
3. A support for cyclo saddles substantially as described and illustrated in
the accompanying drawings.
