Improvements in or connected with Locking Apparatus for Cycles.
We, STANLEY WILLIAM RANDOLPH COLYER of, 66, Christchurch Road, Streatham,
in the County of Surrey, Dentist, and, CHARLES STORK HOLDSWORTH of, 23, Bush
Lane, Cannon Street, in the City of London, Solicitor, 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:-
Our invention relates to improvements in or connected with cycle locks, the
object being to simplify the construction and to provide a thoroughly reliable lock
which can be quickly brought into or thrown out of action, while at the same time
it can be attached to any existing machine with but little difficulty.
Our invention comprises essentially the arrangement of a bar or rod (or & chain
or the like may be employed) pivotally connected to one side of the front or back
forks of the velocipede in such a manner as to engage or lock the back or front
wheel of the machine, or both wheels may be locked. The free end of the locking
har or the like may engage with the lock proper clamped or suitably connected at
the opposite side of the fork, or the bar may be pivotally connected to the look
direct so as to be secured as hereinafter more fully described.
In order that our invention may be more fully understood, we will now proceed
to describe same with reference to the accompanying drawings in which Fig. 1 is
a front elevation of a portion of the front forks of a velocipede showing the
application of our invention thereto. Fig. 2 is a sectional view on line x, x, of
Fig. 1, and Fig. 3 is a detail of the end of the locking bar drawn to an enlarged
scale so as to more clearly show the action of the spring hereinafter referred to.
Fig. 4 shows a slight modified form of our invention, and Fig. 5 is a similar view
showing an alternative form. Fig. 6 is a detail showing the mechanism of a
covering cap or lid.
According to our invention we secure to the one side of the fork f of the
velocipede by means of a clamp e one end of the locking bar b which may be
formed in two parts b, b¹, and screwed together, while to the opposite side of the
fork is secured by means of a clamp c¹ a small lock y of any suitable and well
known construction, one of the kind commonly known as automatic spring locks"
being preferably employed. Around the arm a carrying the locking bar 6 is
arranged a suitable coiled spring s having a projecting arm s secured by small
links to the locking bar b, the object of this spring being to keep the said
locking bar closely against the stop d and parallel to the fork of the machine as
shown in Fig. 1, when not in use.
When it is required to lock the wheel of the velocipede, the locking bar 6 18
raised into the position shown in dotted lines (Fig. 1) the end of the locking bar b
taking into a suitable opening formed in the bottom of the aforesaid lock which,
where an automatic lock is employed, firmly secures the end of the aforesaid locking
bar, or in cases where an ordinary lock is used the end of the bar is secured within
the lock by turning a suitable key.
As a modified form of our invention, and in order to dispense with the attach-
ment on both sides of the velocipede forks, the locking bar & may be nivotally

page_text: connected to a projecting lug h of the lock g as shown in Fig. 4. In this case
the longer arm of the locking bar b extends across the fork passing between the
spokes of the wheel, while the shorter arm k is bent at right angles and enters the
lock as shown at Fig. 4 where it is secured automatically or by turning the key in
the usual manner. A spring m is provided bearing upon a pin n for the purpose
of keeping the locking bar closely down and parallel to the forks of the machine
as shown in dotted lines in Fig. 4, when in the open position, while Fig. 5
illustrates an alternative form wherein the locking bar b is locked or secured at the
pivotal point or joint, by means of the bolt of the lock g, entering a recess or indent
formed in the pivotal end of the said locking bar.
"In some cases where the hole designed to receive the end of the locking bar is
formed or arranged at the top of the lock, we may provide a suitable sliding disc or
cover designed to pass over and close the said hole when the lock is not in use,
(Fig. 6). This lid or cover is furnished with teeth or serrations while the axis of
The locking arm 6 carries a small toothed quadrant 9 designed to engage with same,
so that upon the locking arm b being raised so as to lock the wheel of the
velocipede, the toothed quadrant also turns thus drawing back the sliding disc or
cover and disclosing the hole or entrance.
q
We wish it to be understood that we do not restrict ourselves to any particular
kind of lock but reserve to ourselves the right to employ in connection with our
improved locking mechanism a lock of suitable or convenient construction.
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 cycle lock comprising the locking bar b preferably
formed in two parts b, b, and screwed together aud pivotally connected to a
clamp or the like such as e whereby it may be secured to one side of the forks of a
machine, in combination with a lock g of suitable construction clamped or suitably
connected to the opposite side of the fork and designed to receive and secure the
end of the locking bar, the whole combined and arranged substantially as herein
described and shown, and for the purposes specified.
to
2. In a cycle lock such as above claimed the application or use of a curved or
spiral spring such as having a projecting arms and secured by small links
the locking bar b, substantially as and for the purposes specified.
3. The modified forms of cycle locks lierein described and shown with reference
to Figs. 4 and 5 of the accompanying drawings, and substantially as set forth.
4. The improvements in or connected with cycle locks substantially as herein
described and shown, and for the purposes specified.
