page_text: I, WILLIAM EDWARD WALMSLEY, of 8, Hyde Road, Waterloo, in the County
of Lancaster, Works Manager, do hereby declare the nature of this invention to
be as follows
This invention relates to devices whereby the steering head of a cycle may be
locked in the mid or other position.
Such a device according to this invention consists of a spring actuated bolt
which is adapted to enter and lock the drop tube or piller of the cycle with the
frame thereof.
The spring actuated locking bolt is by preference disposed within a cup which is
screwed into the upper bracket or head of the cycle, and which is provided with a
screwed cap having a milled rim.
Surrounding the bolt is a spiral spring, whose ends abut respectively against a
shoulder on the bolt and the under surface of the screwed cap, and whose tendency
is to press the bolt (when the cap is screwed home) onto the drop tube or steering
piller of the cycle and to cause it to enter a recess or hole therein when the tube
assumes the mid or other position. The outer end of the bolt passes loosely through
the screwed cap and has rivetted to it a plate or disc, by which-when the cap is
unscrewed the bolt is withdrawn from the drop tube or piller, and which also
prevents the cap from being unscrewed too far and being lost.
I also prefer to employ a second spiral spring, which surrounds the spring above
mentioned, and whose ends abut respectively against a shoulder on the inner surface
of the cup and the under surface of the cap, the function of this spring being to
prevent the cap from being inadvertently-as for instance by the vibration of the
cycle-caused to screw inwardly and depress the bolt when the cycle is in motion.
In order to make a good joint between the cup and upper bracket, into which it
screws, I prefer to employ a washer having a concave under surface.
In operation, the cap is screwed inwardly over the cup, thus compressing both
springs and causing the bolt to press upon the drop tube or piller. When, therefore,
the handles are turned to the mid position, or other position at which it is desired
to lock the head, the bolt enters its recess in said tube and locks it. The locking
action may thus be applied in any position of the cycle handles, and only takes
effect when the recess in the drop tube coincides with the spring pressed bolt. By
unscrewing the cap it engages with the disc on the outer end of the bolt and lifts
the latter out of the recess in the drop tube.

I, WILLIAM EDWARD WALMSLEY, of 8, Hyde Road, Waterloo, in the County
of Lancaster, Works Manager, 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 devices whereby the steering head of a cycle may be
locked in the middle or other position.
Such a device according to this invention consists of a spring actuated_bolt,
which is caused to press upon, and ultimately enter a bolt hole in the periphery
of the drop-tube or steering pillar of the cycle and so lock it with the cycle
frame.
In the drawing hereto annexed,
Figure 1 shews the individual parts of the locking device.
Figure 2 is a vertical section of the head of a cycle, fitted with the locking
device.
Figure 3 is a cross section, shewing the drop-tube locked by the device.
Figures 4 to 8 shew the head lock combined with a letter lock.
The spring actuated locking bolt a is disposed within the cup b, which is screwed
into the upper bracket or head c of the cycle, and which is provided with a screwed
cap d having a milled rim.
Surrounding the bolt a is a spiral spring e, whose ends abut respectively against
the shoulder on the bolt and the under surface of the cap d, and whose tendency
is to press the bolt a (when the cap d is screwed home) against the drop-tube or
steering pillar g of the cycle and to cause it to enter the bolt-hole therein when
the tube g assumes the position at which the bolt and hole are opposite one another,
which may be the central position or other desired position. The outer end of the
bolt a passes loosely through the cap d, and has rivetted to it a head or plate i
by which--when the cap d is unscrewed-the bolt a is withdrawn from the
drop-tube and which also prevents the cap d from being unscrewed too far
and lost.
The spring k, whose ends abut respectively against a shoulder in the cup 6 and
the under surface of the cap d, prevents the latter from being inadvertently-as
for instance by vibration of the cycle-caused to screw inwardly and depress the
bolt a when the cycle is in motion. I prefer-for convenience in fitting-that
the springs e and k should have right and left hand spirals, as shewn in the
drawings, and that the spiral of the spring k should be opposite in direction to
the thread of the cap d, in order to minimise friction between the spring and cap
as the latter is screwed inwardly.
In order to make a good joint between the cup 6 and upper bracket c, into
which it screws, I employ a washer m having a concave under surface.
With new
machines, however, a special boss may be formed on the bracket c to receive
the cup b.
In operation, the cap d is screwed inwardly over the cup b, thus compressing the
spring e and causing the bolt a to press against the drop-tube g. When, therefore,
the handles of the cycle are turned to their normal position (or other position at
which the bolt a and hole h are opposite) the bolt a enters the hole / in said tube
and locks it. The cap d may thus be screwed inwardly at any position of the
cycle handles, the effect being that the bolt a presses against the periphery of the
tube 9, and the locking action takes place immediately the bolt a and hole h are
opposite, which may be coincident with the central or other position of the cycle
handles, as desired.

page_text: By unscrewing the cap d it presses against the bolt-head i and lifts the bolt out
of the hole h and thus releases the tube g.
The
As a means of locking the cap d and so guarding the cycle against theft, I
provide it with a letter lock as shewn in Figure 4 (side view) Figure 5 (sectional
side view) and Figure 6 (cross section). The periphery of the cap is grooved to
form teeth n. Around the cap I dispose two, three, or more lettered rings o
within a casing p attached to the cup b. Figure 7 is a plan of one ring o.
rings o have spring pawls o¹, which ride over the teeth n when the cap d is screwed
inwardly, but enter and lock such teeth when the cap is screwed outwardly, the
rings being prevented from turning by the tongues p' whose ends enter the
slots o' therein. The tongues pl have apertures p² for the insertion of a pin or
the like by which they are raised out of contact with the rings o, when the latter
may be turned so that their pawls o' all rest upon the tongue p³ (Figure 8) out of
contact with the cap d when it is desired to unscrew the latter. The letters on the
rings o at the same time form a predetermined combination between the marks p
at each side of the window p' in the casing p.
'
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 :-
1. In combination, as a cycle head locking device, a cup b, a cap d screwing
thereon, a bolt a whose outer end passes through said cap and has a rivetted head i,
and a spring e disposed between the shoulder of the bolt a and the cap d, whereby
as the cap d is screwed inwardly the spring e is compressed and the bolt a is
pressed against the tube g and finally into the hole h, the withdrawal of the bolt
being effected by unscrewing the cap d against the head i, such outward movement
of the cap being limited by the head i when the shoulder / comes in contact with
the underside of the shoulder 1, substantially as described with reference to the
drawings hereto annexed.
2. The employment in combination with the cycle head locking device herein
described, of a spring k which abuts against the shoulder of the cup b and presses
against the under surface of the cap d, whereby any tendency of the latter to
screw inwardly due to the vibration of the cycle-is counteracted, substantially
as described with reference to the drawings hereto annexed.
3. As a means of locking the cap d herein referred to, for the purpose of
guarding the cycle against theft, providing the periphery of such cap with teeth n,
and disposing around such cap two or more lettered rings o within a casing p
attached to the cup b, said rings having spring pawls o¹ which ride over the teeth n
when the cap is screwed inwardly but enter and lock such teeth when the cap is
screwed outwardly, the rings o being prevented from turning by the tongues pl
whose ends enter slots o' in the rings o, said tongues p' having apertures p² by
which they may be raised and the rings o turned so that their pawls o' all rest
upon the tongue p³ out of contact with the cap d when it is desired to unscrew the
latter, the letters on the rings o at the same time forming a predetermined
combination between the marks pt on the casing p, substantially as described with
reference to the drawings hereto annexed.
