Improved Means for Locking Cycle Steering Wheels.
JOHN CROSHAW WILSON Park Ravine Nottingham Hosier do hereby declare
the nature of my said invention to be as follows:-
This invention has for its object the provision of certain and simple means for
locking the fork of cycle steering wheels in a fixed position so that the cycle cannot
be steered until the fork has been unlocked.
According to this invention the fork tube is provided with one or more bolts.
which are fitted to slide in guides inside the tube, and are actuated by a lever
which is capable of turning and sliding with or on its axle. This lever or its axle
is held to or from the bolts by means of a spring, and the bolts are locked in
position by a catch, which may be in the form of a pin on the lever or its axle, and
suitable fixed recesses, so that, before the lever can be turned, it, or, its axle must
be moved to or from the bolts until the movable part of the catch is clear of the
fixed part. A key is used for actuating the lever, and the fork is locked by the
bolts being shot through the fork tube into openings in the crown tube.

JOHN CROSHAW WILSON Park Ravine Nottingham Hosier 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 :-
This invention relates to an improved locking appliance for cycles, the object
being the provision of means for locking the cycle front wheel the said means being
contained within the steering head of the machine.
The improved lock comprises one or more bolts preferably fitted to slide in
guides and actuated by a lever which is fitted to slide on or with its axle to or from
the bolts, and is provided with a spring for holding it to or from the bolts and with
means for holding it in its placed position.
In the accompanying drawings illustrating this invention
Fig. 1 is a side vertical section, and
Fig. 2 is a front vertical section.
The tube a carries the fork for the front wheel of the cycle and is fitted to turn
in the usual way within the outer tube 6 which is carried by the cycle frame. At
any convenient position between the bearings of the tube a there is fitted a piece c
which is attached to the tube by rivets or other suitable means. This piece is
provided with grooves for receiving the sliding bolts d and e which are provided with
projecting pins f. In the centre of the piece c there is a bearing for the axle h of
a lever g, the axle having a collar and a squared end h2, while the bearing is
recessed to receive a spring k. The ends of the lever g are slotted to fit over the
D

page_text: pins on the slides d and e and at some convenient position there is a pin land
in the piece e there are two holes m and n arranged to receive the pin l. The
tubes a and b are drilled at o to allow of a key being inserted and at p and q for
receiving the ends of the bolts e and d, these holes being arranged in conjunction
with the other parts to allow of the front wheel being locked in any determined
position. In the drawings the lever g is shown in its central position, and when
the cycle wheel is to be locked, the front fork is turned until the holes o p and q in
the tube a are opposite the corresponding holes in the tube b. The key is then
inserted in the hole o and pressed against the collar h¹. This compresses the
spring k, pushes back the lever g; removes the pin from the hole m, and allows
the lever g to be turned, this latter shooting forward the bolts through the holes p
and g; and on removing the pressure from the axle the pin enters the hole in and
locks the bolts so that they cannot be shot back from the inside.
In a modification the lever is fitted to slide on its axle instead of with it, a
different arrangement of spring is used and a projection on the lever is arranged
to fall into grooves cut in the boss of the bearing for the lever axle.
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
cláim is:-
1. A lock for cycle steering forks fitted wholly within the steering head and
comprising one or more sliding bolts actuated by a lever fitted to slide on or with
its axle, to and from the bolts and a spring and catch for holding the bolts in the
locked or unlocked position as herein set forth.
2. A lock for cycle steering forks fitted wholly within the steering head and
constructed as herein shown and described.
