Improvements in cycle saddles
Year: 1897

page_text: I, WALTER GRIFFITHS, of Highgate Square, Moseley Road, Birmingham, in the
County of Warwick, Manufacturer, do hereby declare the nature of this invention to
be as follows:-
My invention has for its object "Improvements in cycle saddles" by which I
provide a freedom of movement in the seat at the fore end which enables the sides of
the seat to automatically accomodate themselves to the movement of the legs. By
my invention the centre of the fore part of the seat is divided so as to form a space
in the centre and the two sides of the seat are so turned over as to form a support on
each side which is particularly easy to the rider and avoids injurious pressure on the
vital parts.
In carrying my invention into effect I divide the fore end of the seat of the saddle
into two parts each part of which is doubled over into two thicknesses and attached
to each side of a frame which is mounted to turn on a vertical pivot. This vertical
pivot is mounted to turn on a horizontal pivot which also forms the adjusting screw
between the seat and the support. The horizontal pivot pin is provided with a half
round nut which works in a cup-washer which is suitably attached to the support, so
as to enable the said horizontal pin to have a ball and socket movement with regard
to the support and this arrangement is applied to both ends of the pin, a lock nut
being provided to lock against the square side of the half round nut. The action is
as follows. When the right leg is down the frame turns on both the vertical and
horizontal pivots and allows that side of the seat to give both longitudinally and
vertically until the right leg is up and the left leg is down, when a similar action
takes place on the reverse side of the saddle and thus the seat is constantly
accomodating itself to the movement of the legs.

I, WALTER GRIFFITHS, of Highgate Square, Moseley Road, Birmingham, in the
30 County of Warwick, Manufacturer, 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:-
My invention has for its object "Improvements in cycle saddles" by which I

page_text: the seat to automatically accomodate themselves to the particular movement of the
parts of the rider affected by which I provide a saddle particularly easy to ride upon
and avoids any injurious pressure to the vital parts.
For a clear description of my invention I have added hereto a sheet of drawings
upon which I have fully illustrated the nature of my said improvements.
Figure 1 is a plan of the saddle.
Figure 2 is a longitudinal section.
Figure 3 is a front elevation.
Figure 4 is a part sectional plan.
my
In carrying my invention into effect I divide the fore end of the seat of saddle 1
into two parts, each part of which is doubled over as shewn by C1 and C2 Figure 1,
and which are attached respectively to the arms and 62 of the plate B. This
plate B is cupped at 63 to receive the ball pivot A by which it is supported in such a
manner as to have a sufficient amount of freedom to allow the fore ends C1 and C2 to
follow the action of the rider. It will be seen that the ball pivot not only gives a 1
vertical reciprocating action but also a similar action in a horizontal direction as shewn
by dotted lines in Figure 4, by which means upon the depression of the one side a
consequent increase in the flexibility of the seat on that side is obtained with
proportionate decrease of the flexibility on the other side and vice versa.
For limiting the amount of action of the plate B and for retaining the cup on the
ball A the pin D is provided with the half round head d' and half round nut d² both
working in half round cups formed in plate B and support F the holes through which
the pin D passes being made with sufficient clearance to allow freedom for the pin D
to move.
at
5 By these means the fore parts C¹ and C2 of the seats not only respond by a vertical
movement to the action of the rider but the flexibility of the seat is also increased
and decreased as required by such action of the rider.
I do not confine myself to the exact details so long as the divided fore end is
connected by a double or ball joint through which I obtain a compensating tension
of the sides of the seat in combination with the reciprocating action of the fore
end.

Having now partienlarly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1st. In a divided cycle saddle the ball joint A or its equivalent for obtaining a
compensating tension of the sides of the seat in combination with a reciprocating
action of the fore ends C¹ and C2 substantially as and for the purpose herein set forth
and shewn upon the accompanying drawings.
