Improvements relating to Locking Appliances for the Steering Heads
of Cycles and other Road Vehicles.
I, EDWARD JONES, of Kynoch Limited, Lion Works, Witton, in the County
of Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention consists of improvements relating to the steering heads of
cycles, motor cars, and the like road vehicles, my object being to provide simple
and effective means capable of ready manipulation whereby such a steering head
can be locked or prevented from rotation within the socket or framing when
required, the parts from which the locking or fastening device is formed being
neatly arranged in a convenient position and in such a manner as to prevent
any scratching or damaging of any part of the finished surface of the machine.
In the construction of a steering head locking device in accordance with my
invention for attachment to an existing cycle, I employ a double eyed clamping
piece or locking body which fits over the upper part of the top socket lug and
also over the portion of such lug which receives the top or connecting tube of the
cycle frame. The portion of the locking body embracing the top tube or con-
necting tube portion of the lug is in part formed by a cap which must be detached
to permit of the locking body being placed in position. The cap is connected
to the body or main part by screws which when tightened up securely clamp
the complete locking body or bracket in position.
On the upper surface of the locking body or bracket I form a guiding groove
for the locking bolt, such bolt having a wedge like head shaped on the inner
side to the curvature of the ball head clip. On tightening the nut on the
opposite end of the bolt the wedge like head is drawn tightly between its guide
on the one side and the ball head on the opposite side and the latter is thus
prevented from rotation.
I preferably face the wedge head with leather or other suitable substance,
which I attach in any convenient manner.
In the application of my invention to cycles when under construction I prefer-
ably form the bracket or projection or projections for the reception of the locking
bolt in one with the top socket lug of the cycle frame.

page_text: what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention consists of improvements relating to the steering heads of
cycles, motor cars, and the like road vehicles, miy object being to provide simple
and effective means capable of ready manipulation whereby such a steering head
can be locked or prevented from rotation within the socket or framing when
required, the parts from which the locking or fastening device is formed being
neatly arranged in a convenient position and in such a manner as to prevent
any scratching or damaging of any part of the finished surface of the machine.
In the accompanying sheet of explanatory, drawings to be hereinafter referred
to.

Figure 1 is an end elevation; Figure 2 a side elevation, Figure 3 a plan, and
Figure 4 a sectional plan of the top socket lug of a cycle frame and a portion of
the steering head having my invention applied thereto.
The same reference letters in the different views indicate the same parts.
In the construction of a steering head locking device or a cycle head-lock in
accordance with my invention, I form with or attach to the top socket lug A a
bracket or projection A¹, such bracket or projection having a guiding groove cut.
or formed through it for the reception of the locking bolt B. The bolt B has a
wedge like head which is shaped on the inner side to the curvature of the ball
head clip C. On tightening the nut D on the opposite end of the bolt the wedge.
like head is drawn lightly between its guide and abutment on the one side and
the ball head clip on the opposite side and the latter is thus prevented from.
rotation.
I preferably face the wedge head with leather or other suitable substance,"
which I attach in any convenient manner.
In the application of my invention to cycles when under construction I prefer-
ably form the bracket or projection or projections as A, for the reception of the
locking bolt B, in one with the top socket lug A of the cycle frame, but in
applying it to existing cycles the bracket is made as a projection from a clamping
or embracing piece which is connected to the top socket lug in any convenient
manner.
Having now particularly 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.
1. In locking appliances for the steering heads of cycles and other road vehicles,
the combination and arrangement of a locking bolt between a portion of the
steering head and a guide and abutment formed with or attached to a part of
the vehicle framing, substantially as described.
2. A cycle head lock constructed and arranged substantially as described and
as illustrated.
