PROVISIONAL SPECIFICATION.
Improved Means for Locking Cycle Wheels, applicable also
as a Brake.
We, CAMPBELL WARD, of Luny House, Teign Street, Teignmouth, Brewer,
and WILLIAM BOBBETT, of 1, Brimley House Villas, Teignmouth, Coachbuilder,
do hereby declare the nature of this invention to be as follows:-
This invention consists in mechanism for locking cycle wheels through the medium
of the brake. It is applicable also as a brake..
The improved mechanism in which this invention consists is constructed, arranged,
and operated, as follows:
Upon the steering pillar is a collar to which is secured a sleeve internally screw-
threaded and telescoped at its lower end over a cylindrical socket closed at the
bottom and carried in a collar secured to the brake rod. In the screw-threaded
sleeve aforesaid is a screw spindle adapted to work in the sleeve. At its lower end
the said screw-spindle bears against the inner face of the bottom of the cylindrical
socket. A removable key of special design is employed to turn the screw spindle
in the sleeve, and through this key only the screw can be so turned when the
mechanism is in place on the cycle. By turning the screw spindle in the proper
direction the brake, which is of an ordinary spoon or brush pattern, is lowered on
to the wheel tyre and bears thereon with a pressure depending on the extent to
which it is forced down. By this means the wheel can be prevented. from rotating.
The wheel is released by turning the screw spindle in the reverse direction to that
required for screwing it down. The key being, as aforesaid, removable, can be
taken away after locking the wheel which can only be unlocked by the use of the
said key.
By the provision of winding reels, or the like, situated at convenient points along
the handle-bar, the brake can be operated through the medium of wires, or their
equivalents, attached to the key aforesaid and to the winding devices.
Under a modification a worm is carried upon the spindle operated by the key,
and a rack is carried upon the brake rod. The worm gears with the rack. The
mechanism is protected by a guard.

page_text: he performed, to be particularly described and ascertained in and by the following
statement:-
This invention consists in mechanism for locking cycle wheels through the medium
of the brake. It is applicable also as a brake.
The improved mechanism in which this invention consists is constructed, arranged,
and operated as follows:-
Clamped to the handle-bar or to the steering pillar of the cycle is a collar to
which is secured a sleeve internally screw-threaded and telescoped at its lower end
over a cylindrical socket closed at the bottom and carried by a collar or bracket,
either secured to or adapted to act upon the brake rod. In the screw-threaded
sleeve aforesaid is a screw spindle adapted to work in the sleeve as a nut. At its
lower end the said screw spindle is secured to but free to turn in the bracket which
carries the socket aforesaid. A removable key is employed to turn the screw
spindle in the sleeve, and by this key only, or by a key precisely similar, the
screw can be so turned when the lock is in place on the cycle. By turning the
screw spindle in the proper direction the brake, which is of an ordinary spoon or
brush or other pattern, is lowered on to the wheel tyre and bears thereon with a
pressure depending on the extent to which it is forced down. By this means the
wheel can be braked and can be prevented from rotating. The wheel is released
by turning the screw spindle in the reverse direction to that required for screwing
the brake down. The key being, as aforesaid, removable, can be taken away after
locking the brake, which can only be unlocked by using the said key.
Referring to the accompanying sheet of illustrative drawings, Fig. 1 represents
a front view of one form of our improved lock for cycles. Fig. 2 is a side view.
The locking device consists of a sleeve a attached by the clamping bracket.b to
the handle-bar c of the cycle. It might be secured to the steering pillar of the
cycle. The sleeve a is screw-threaded throughout a part of its length, and, in
the screw threads, as in a nut, works the spindle d which at the lower end is
secured to but free to turn in the bracket e which extends over the top of the
brake rod f. A tubular socket g secured to the bracket e is telescoped into the
sleeve a. It serves as a guard to prevent access to the lower part of the screw
spindle d. A removable key h fits on the head or upper end of the spindle d
which can be turned only by means of the said key, or a similar key. When it
is desired to put the lock into operation, the key h is turned in the proper direction
and the bracket e moved down to bear upon the head of the brake rod which,
by continued screwing down, applies the brake to the wheel of the cycle with a
degree of pressure depending on the extent to which the spindle d is screwed down.
If, now, the key h be removed, the brake cannot be taken off, and until the said
key, or a key precisely similar, is applied and the spindle d thereby turned in the
requisite direction, and the brake released through the agency of the key and the
usual brake releasing spring, the cycle wheel remains locked, and the machine
cannot be wheeled away. The keys, and spindle heads which the keys fit, are
intended to be different in all machines, so that the same key shall not fit more
than one spindle head.
In the example shown at Figs. 1 and 2 of the drawings, the usual hand-brake is
employed and is free to be operated independently of the lock. In some cases the
bracket e of the lock may be counected to the brake rod and the brake lever f
may be dispensed with; the lock then serving both as a lock and a means of
applying the brake.
At Fig. 3 is shown in front view, and at Fig. 4 in side view, a modification of
this invention. In this arrangement the bracket i is furnished with a hook i which,
by operating the screw spindle in the internally screw-threaded sleeve a by the
special key and telescopic tubular socket g, can be made to engage and pull up
the usual brake lever k and so cause the brake rod, to which the lever k is, as is
usual, connected, to be depressed, and thus the brake is applied to the wheel of the
cycle. In this modification also, the braking mechanism is not coupled to the lock
and may be operated independently.

page_text: Having now particularly described and ascertained the nature of this inven-
tior, and in what manner the same is to be performed, we declare that what we
claim is :-
1. An appliance for locking cycle wheels through the medium of the brake;
consisting of an internally screw-threaded sleeve such as a, clamped or otherwise
secured to the handle-bar, steering pillar, or other suitable part of the cycle, a
screw spindle such as d operated to screw up and down in the sleeve through the
medium of a removable key and thus to raise and lower a bracket such as e or its
equivalent, which, by pressing on the rod carrying the brake block, causes the
brake to be applied to any desired degree of pressure, substantially as hereinabove
described with reference to Figs. 1 and 2 of the accompanying drawings.
2. The modification herein above described with reference to Figs. 3 and 4 of the
accompanying drawings; in which the screw operated bracket of the lock is
furnished with a hook which, by being raised through the medium of the removable
key and screw spindle of the lock, tilts the brake lever and thus causes the brake
to be applied to the cycle wheel.
