PROVISIONAL SPECIFICATION.
A New or Improved Locking Apparatus for Cycles.
We, ANDREW DOUGLAS BOWIE, Cabinet Maker, and the Reverend HENRY
BRAY, both of Kirkcudbright, North Britain, do hereby declare the nature of our
said invention to be as follows:-
The object of our invention is to manufacture a new or improved construction of
lock for securing cycles against theft, the lock being readily applied to cycles now
in use, and the operation of locking greatly facilitated.
According to our invention, as applied to a rear driven safety bicycle, we clamp
or otherwise secure a pivoted bar or lever to one leg of the upper back fork,
preferably the left. This bar or lever is fixed to the left leg in such a position
that when in its locked position, the bar passes between the spokes of the wheel
and close to the rim and rests in a fork fixed on the right leg of the fork. The
bar or lever is connected with a sliding lock by a link so that on raising the lock
upon the left fork, the bar is placed in its locked position and on lowering the lock,
the bar is moved to a position approximately parallel to left leg of the fork.
A segmental ribbed plate is sometimes attached to the clamp, upon which the
lock is capable of sliding, the ribbed plate being formed to fit the shape of the leg
of the fork. The lock is formed with a band or clamp to encircle both the leg
and the plate and is fitted with a hook, bolt or other, preferably self-acting,
projection to enter a correspondingly formed hole in the plate when in its locked
position.
In some cases the segmental ribbed plate may be dispensed with, the lock
sliding directly on the leg which is drilled to receive the hook, bolt or other
fastening of the lock.
The lock is enclosed in a case or cover and operated with the aid of a key, by
preference.
COMPLETE SPECIFICATION.
A New or Improved Locking Apparatus for Cycles.
We ANDREW DOUGLAS BOWIE Cabinet Maker and the Reverend HENRY
BRAY both of Kirkcudbright North Britain, do hereby declare the nature of
our said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of our invention is to manufacture a new or improved construction of
lock for securing cycles against theft the lock being readily applied to cycles now
in use and the operation of locking being greatly facilitated.
And in order that our said invention may be particularly described and
ascertained reference is hereby made to the accompanying drawings in which
similar figures of reference indicate corresponding parts illustrating the application
of our invention to a rear driven safety bicycle.

lever 6 is pivoted at 7 to the clamp 5 in such a position that when it is raised and
locked as shewn in Figure 2 the bar passes between the spokes of the wheel
close to the rim 8 and becomes engaged in a box staple 9 integral with a fixed
clamp 10 attached to the right leg 4 of the fork. 11 is a sliding collar having a
lock 12 attached thereto and capable of sliding up and down the segmental
plate 13 attached to the leg 3. 14 is a rib or feather integral with the plate 13
the case of the lock 12 being recessed to fit the same. 15 is a notch formed in the
feather to receive the latch or bolt of the lock which is preferably made self
locking. 16 is a channel shaped link pivoted at 17 to the sliding collar 11 and at 18
to the locking bar 6.
When the cycle is travelling the apparatus is retained in the position shewn in
Figure 1 and when it is necessary to lock the wheel the collar 11 is raised to the
position shewn in Figure 2 in which position the collar 11 is locked the bar 6
passes between the spokes of the wheel the end of the bar becoming engaged in the
box staple 9 and thereby preventing the rotation of the wheel.
The apparatus is unlocked by means of a key 19 inserted in the lock 12 and
releasing the bolt or latch.
In some cases the segmental ribbed plate 13 may be dispensed with the collar 11
and lock 12 sliding directly on the leg which is drilled to receive the hook bolt
latch or other fastening of the lock. Also the collar 10 may be dispensed with a
slot being made in the leg 4 to receive the end of the bar 6 when locked.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1. The new or improved locking apparatus for cycles substantially as herein before
described and illustrated by the drawings.
2. In apparatus for locking the wheels of cycles the combination of one or both
of the fixed collars 5 and 10 attached to the fork of a wheel a sliding collar 11
carrying a lock 12, a locking bar 6 pivoted to the collar 5, a link 16 pivotted to
the sliding collar 11 and to the locking bar 6 the sliding collar 11 sliding upon a
segmental plate 13 fitted with a rib or feather 14 all severally and collectively
operating substantially as herein before described and illustrated by the drawings.
3. In apparatus for locking the wheels of cycles the combination of a fixed
collar 5 attached to the fork of a wheel a sliding collar 11 carrying a lock 12 a
locking bar 6 pivoted to the collar 5 a link 16 pivoted to the sliding collar 11 and
to the locking bar 6 the bolt or latch of the lock entering an opening in the leg 3
and the locking bar 6 entering an opening in the leg 4 substantially as hereinbefore
described and illustrated by the drawings.
