An Improved Locking Device for Cycles.
I, Captain Hon. ROBERT CHARLES DRUMMOND, of 36, South Eaton Place,.
London, S.W., 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 an improved locking device for cycles, and has for object
to provide an article of this class that shall effectually prevent an unauthorized
person riding or wheeling away a cycle fitted with the device when the former is
left outside a house or when otherwise left unattended. And in order that this my
invention may be the more readily understood and carried into practical effect,
reference is hereby made to the accompanying sheet of illustrative drawings
wherein :
Fig 1 is a perspective view of a portion of a cycle shewing the lock in its closed
position thereon, the position it assumes when out of use being indicated by dotted
lines. Fig. 2 is a view, also in perspective of the lock itself, and Fig. 3 a view
similar to Fig. 1, but shewing an addition to the rim of a wheel of a cycle.
Referring to the drawings wherein like letters of reference indicate corresponding
parts, a is a bolt of rectangular shape, hinged at 6 working on a barrel or case e
containing locking mechanism of any suitable and well known form.
If desirable the barrel or case c may be of eliptical or other convenient form in
section and the bolt hinged thereto in any suitable manner.
The locking device is attached to one of the rear forks (preferably the near side
one) of the cycle by means of a collar e or its equivalent, in such a manner as to
render the removal of the clip a matter of impossibility to any person not provided
with the key or the appliance for unfixing it.
The locking device is fitted on the rear fork d, by removing the wheel 9, and
slipping the collar e over and along the said fork d, to its desired position, when it
is secured in place by means of the thumb-screw e¹ (Fig. 3) or the nutted bolt e
(Figs. 1 and 2) or their equivalent.
In operation, the bolt a is turned on its hinge b until such bolt is at right angles
to the fork d and is between two of the spokes g₁ of the rear wheel g, close up to
but not actually in contact with the rim thereof in which position the said bolt a
is locked or secured in any suitable manner, thereby effectually preventing the
wheel g, or the pedals being revolved.
If desirable the bolt a may be covered with india-rubber, felt or other suitable
yielding material or substance for the purpose of preventing injury to the spokes or
rim of the wheel 9. Referring particularly to Fig. 3, I have there shewn two studs
or projections h fixed to, or formed integral with the rim 92 of the wheel g, between
which studs or projections the bolt a passes. By this means all unnecessary play
of the wheel is taken up and the danger of injury to the spokes obviated.

page_text: 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 improved device for locking the wheel of a cycle, substantially as
described and illustrated.
(2). In a locking device for cycles, the hinged bolt a in combination with studs or
projections 2 upon the rim of the wheel, substantially as and for the purpose herein-
before described and shewn upon the drawing.
