PROVISIONAL SPECIFICATION.
Improved Head-lock for Cycles.
I, WILLIAM LOCK, of Tindal Villas, Brentwood Road, Romford, in the County
of Essex, Under-foreman to the New Ormonde Cycle Company, Limited, do hereby
declare the nature of this invention to be as follows:-
-
The invention has for its object a simple construction of head-lock for cycles.
In carrying my invention into effect 1 form the lower lug of the head with a boss
or projection, and I bore a hole centrally through the same, through the head tube,
and through the steering tube which passes through the head. I have thus a clear
passage from the exterior to the interior of the head. In the interior of the
steering tube I place a spring-actuated stud, which accurately fits the hole formed
in the two tubes and lug. This stud has a tendency to project through the hole in
the steering tube into that in the head when such parts are in a straight line and
thus to keep the head locked. The boss upon the lower lug is screw-threaded, and
when the screw which works in it is screwed up tightly, the inner end thereof fills
up the hole in the head tube and presses the spring-actuated stud back into the
steering tube. The head tube has under these conditions a smooth inner surface,
against which the spring-actuated stud will press, but as the pressure is only slight
it will not interfere with the free steering of the machine. The spring-actuated
stud is formed with a collar on its inside end to prevent it falling out when the
screw is entirely removed, or it may be made of tapered form for the same
purpose. It will be understood that the screw may be prevented from unscrewing
by any convenient means, such, for instance, as a lock-nut, and that the head-lock
constructed as above described may be applied to other parts of the head.

I WILLIAM LOCK of Tindall Villas, Brentwood Road, Romford, in the County
of Essex, Under-foreman to the New Ormonde Cycle Company, Limited, do hereby
0 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:

page_text: projection (a Figs. 4 & 5.) through the head tube (b. Figs. 4 & 5.) and through the
steering tube (c. Figs. 4 & 5.) which passes through the head. I have thus a clear
passage from the exterior to the interior of the head.
In the interior of the steering tube I place a spring actuated stud (Figs. 1 & 2)
which accurately fits the hole formed in the two tubes (b. & c. Figs. 4 & 5.) and
boss or projection (a. Figs. 4. & 5.).
This stud (Fig. 2) has a tendency to project through the hole in the steering
tube (c. Figs. 4 & 5.) into that in the head tube (b. Figs. 4 & 5.) when such parts
are in a straight line and thus to keep the head locked.
The boss or projection (a. Figs. 4 & 5.) upon the lower lug of the head is screw-
threaded and when the screw (Fig. 3.) which works in it is screwed up tightly the
inner end thereof fills up the hole in the head tube and presses the spring actuated
stud (Figs. 1 & 2) back into the steering tube (c. Figs. 4 & 5.). The inner surface
of the head tube (b. Figs. 4 & 5.) has under these conditions a smooth surface
against which the spring actuated stud (Figs. 1 & 2) will press, but as the pressure
is only slight it will not interfere with the free steering of the machine.
It will be understood that the screw (Fig. 3) may be prevented from unscrewing
by any convenient means, such for instance as a lock nut, and that the headlock
coustructed as above described may be applied to other parts of the head.
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. The combination of a spring and stud controlled by a screw.
2. The combination of a head-lock with a block provided with a spring, stud and
-screw.
3. The combination of a spring and stud controlled by a screw working into the
holes in the two tubes and lug.
