PROVISIONAL SPECIFICATION.
A New, or Improved Method of Mounting the Saddle or Seat
Support of Cycles and other Vehicles.
I, ALFRED MAYHEW, of 80, Windmill Street, Gravesend, in the County of
Kent, Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to the mounting upon the frame of the support which
carries the saddle or seat of vehicles and is more especially designed for cycles,
the object being to minimise shocks to the rider due to inequalities of surface and
the consequent checks to speed produced thereby; also to reduce friction between
rider and saddle and to facilitate riding.
According to my invention to that part of the frame which is intended to carry
the seat attach what may be termed a "radial motion " arrangement which
consists essentially of one or more bars pivotted to said frame or support and
projecting for a suitable distance rearwardly and adapted to vibrate about the pivot
only in radial directions; the rearward ends are pivotted together and also to a bar
frame or support which carries the saddle or a part in connection therewith. This
bar frame or support extends horizontally forward and passes freely through an
oscillating guide bearing block carried by the supporting part. This bar frame or
support is fitted in convenient position with a spring or springs adapted for
approximately horizontal action, or equivalently a mass of resilient material may
be used, and so arranged as to take up and counterbalance all stresses produced
during and by the motion of riding.
By the above described arrangement strains in the frame are reduced, and hence
lighter sections of material can be used, also the strains upon the arrangement
described being transmitted approximately in longitudinal directions do
appreciably check progression as 18 the case with vertically arranged saddle
springs.

COMPLETE SPECIFICATION.
A New or Improved Method of Mounting the Saddle or Seat
Support of Cycles and other Vehicles.
I, ALFRED MAYHEW, of 80, Windmill Street, Gravesend, in the County of
Kent, Engineer, do hereby declare the nature of this invention and in what
manner the saine is to be performed to be particularly described and ascertained
in and by the following statement:-
My invention relates to the mounting upon the frame of the support which
carries the saddle or seat of vehicles, and is more especially designed for cycles,
the object being to minimise shocks to the rider due to inequalicies of surface and
consequent checks to speed produced thereby; also to reduce friction between rider
and saddle, and to facilitate riding and prevent saddle soreness.

According to my invention to that part of the frame which is intended to carry
the seat attach what may be termed a radial motion arrangement, which
consists essentially of one or more bars pivotted to said frame or support and
projecting for a suitable distance rearwardly, and adapted to vibrate about the
pivot only in radial directions; the rearward ends are pivotted together and also
to a sliding bar frame or support which carries the saddle or a part in connection
therewith. This bar frame or support extends horizontally forward and passes
freely through an oscillating guide bearing block carried by the supporting part.
This bar frame or support is fitted in convenient position with a spring or springs
adapted for approximately horizontal action, or equivalently a mass of resilient
material may be used, and so arranged as to take up and counterbalance all stresses
produced during and by the motion of riding.
I will fully describe my invention in reference to the accompanying drawing, in
which
Fig. is an elevation; Fig. 2 a sectional elevation; Fig. 3 a plan; and Fig. 4
a rear end elevation of my improved method of mounting saddles as applied to
cycles.
A is the adjustable seat pillar, to the head of which a pair of rearwardly
projecting bars B B are pivotted at bb, or equivalently a rigid bracket may be
employed. The rear ends of these bars may be bent upwards or curved as shown,
and they are pivotted together and also to the bar C at c. To this bar C the arm
of the saddle L is attached in suitable position, and the forward portion C¹ of
the bar C is or may be reduced in diameter, and projects horizontally forward and
passes freely through and beyond an oscillating guide bearing block D which is
attached by a pin d to an extension A¹ of the seat pillar A. This extension is
shown in the drawing as projecting forward, which is the preferred construction,
but it may be lineable with the seat pillar or project rearwardly if desired. The
movement of the bar C C is controlled by the spring or springs S which are of
suitable strength, and their resiliency is or may be adjustable by a cap F screwed
upon the forward end of the sliding rod C₁, suitable washers f' being provided
for receiving the end thrusts of the springs S.
By this arrangement when the weight of the rider is upon the saddle the parts
will assume more or less the position shown in Figs. 1 and 2, the normal position
being shown dotted in Fig. 1, the bars B moving in a downward radial direction,
and imparting a rearward longitudinal movement to the rod C in the direction of
the arrow thereby compressing the springs S, the action of which counterbalances
and takes up all weight, vibration, and stresses produced during and by the motion
of riding; furthermore, all strains in the frame being reduced, lighter sections of
material can be used, also the strains upon the "radial motion arrangement being
transmitted approximately in a longitudinal direction do not appreciably check
progression as is the case with vertically arranged saddle springs.
"
By further screwing up or unscrewing the cap F the saddle may be raised or
lowered by the rider without dismounting to suit any gradient he may encounter,
thereby enabling him to assume a more vertical and efficient position.
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 is :-
1. The method of mounting the saddle or seat support of cycles and other
vehicles in the manner hereinabove described, so that it shall be capable of radial
motion behind or about the seat pillar for the purpose specified.
2. The arrangement for mounting the seat consisting of the saddle-carrying
bar C connected at its rear end to the rearwardly projecting bracket or bars B
pivotted to seat pillar A, and carried at its forward end in an oscillating guide
block D attached to the pillar head, said bar C being fitted with springs S, aud
screw cap F, so that by varying the compression on the springs the position of the
saddle may be varied as required, substantially as herein before described.

described and illustrated in the drawings.
