Improvements in Saddle Supports for Safety Bicycles.
HENRY LURKINGS Carpenter and Joiner Shrewley near Warwick do hereby
declare the nature of this invention to be as follows:-
The saddle pillar to work up and down in the socket in which it is usually fixed.
To be lifted up by means of coil spring. The weight of the rider to force it down
at will. A small cylindrical spring bolt attached to front side of socket, shooting
through socket into hole in pillar, when pillar is elevated or down, the pillar is
kept in position by a small pin screwed in back side of pillar the head of which
projects working up and down in slot cut in back side of socket, which also
regulates the distance of rising or lowering of pillar. The bolt is drawn by means
of lever attached to handle bar (similar to brake lever) which forces down a
socket bracket working up and down stem of handle bar, which is connected to a
crank attached to underside top bar of frame by 2 small rods, the crank is
connected to cylindrical bolt by a thin steel rod.
For ladies machines it requires 2 cranks instead of one to carry connecting rods
round with frame.

Improvements in Saddle Supports for Safety Bicycles.
I, HENRY LURKINGS, Shrewley, near Warwick, Carpenter and Joiner, 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 saddle pillar to work up and down in the socket in which it is usually fixed.
To be lifted up by means of coil spring.
The weight of the rider to force it down at will. A small cylindrical bolt
attached to front side of socket, shooting through socket into hole in pillar when
elevated or lowered, the pillar is kept in position by a small pin screwed in back
side of pillar the head of which projects and works up and down slot cut in
back of socket, and which also regulates the distance of raising or lowering
of pillar.
The bolt is drawn by means of a lever attached to the handle bar, such as those
now in use, which forces down a socket bracket working up and down the stem of
the handle bar, which is connected to a crank attached to the underside of the top
bar of the frame by two small rods, the crank is connected to the cylindrical
bolt by thin steel rod.
For ladies machines it requires two cranks instead of one to carry connecting
rods of a round form or shape with the frame.
In order that my invention may be fully understood I now refer to the annexed
drawings in which :-
Figure 1. side elevation of my invention adapted for a gentleman's machine.

Figure 3. sectional side elevation of my invention adapted for use with a ladies
machine.
g
a is the pillar or rod carrying the sadle which bears upon a spiral spring b
contained in the tube or framing c; d is a bolt controlled by the spiral spring
which enters apertures in the sliding pillar a so maintains same at various heights,
the bolt d and spring e are carried in a casing attached to the collar which
encircles the hollow frame tube c, i being a set screw which engages in the groove h.
in the sliding pillar a. The bolt d is connected to the bent lever j pivoted at k,
through the medium of the rod or wire l. This bent lever j is operated by the
rod or bar m which is pivoted to the sliding collar n which is operated by the
lever o which is pivoted at p. to the handle bar q; it will be seen that by releasing
the bolt d. from the pillar a the same will descend under the weight of the rider
thus compressing the spring band can be retained by the bolt d. engaging in an
aperture or recess in the pillar a. By releasing the bolt d. and reducing the
weight upon the saddle the spring b will again raise the saddle to its initial or
highest position.
In Figure 3. an arrangement suitable for a ladies machine is shown, in which
the bolt d is released through the medium of the pivoted bent lever r, rod or
wire bent pivoted lever t, rod or wire u, and bent pivoted lever v, w being the
rod which is operated by the lever o as before for the purpose of releasing the
bolt d from the pillar a, the pillar a and spring 6 being arranged as before in
the hollow frame tube c.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
In supports for saddles or seats for bicycles, tricycles, and the like, a pillar
carrying the saddle or seat and resting or bearing upon a spring contained in a
hollow frame tube, said pillar sliding in same, and having recesses or apertures in
which a
locking bolt controlled by a spring engages, said locking bolt being
operated by suitable connecting levers and rods; substantially as described and
illustrated.
