An Improved Locking Device applied to Cycles for Preventing Theft
of same.
I JAMES WHITEWOOD of Claygates Cottage, Buxted in the County of Sussex,
Farm Bailiff, do hereby declare the nature of this invention to be as follows:-
This Invention relates to an improved locking device applied to cycles for pre-
venting the use of the machine when required and thus obviating the risk of theft.
For this purpose I form or fix upon one of the side tubes of the rear fork a
projection or case somewhat similar to a padlock fitted with a spring bolt or lock
and a keyhole for locking or unlocking by means of a key.
Upon the other tube of the said fork and opposite the locking case I attach an
arm or lever pivoted to the tube or to a sleeve or bracket riveted or otherwise fixed
to the tube and I provide the said arm or lever with a spring for keeping it in a
vertical line with the tube of the fork when in its unlocked position.
When required to lock the wheel of the cycle the arm or lever is turned so as
to pass between the spokes of the wheel its end entering a slot formed on the
inner side of the locking case wherein it is locked by means of a key which can
be removed and applied again as in an ordinary padlock for unlocking the wheel
when required.
Any suitable lock may be formed upon the machine in the manner described.
so that it engages with the bar as before referred to.

COMPLETE SPECIFICATION.
An Improved Locking Device applied to Cycles for Preventing Theft
of same.
I JAMES WHITEWOOD of Claygates Cottage, Buxted in the County of Sussex,
Farm Bailiff, 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:-
My Invention relates to an improved lock for cycles for preventing misappro-
priation of the same and consists in applying the said lock to one or other of the
wheel of the cycle so as to render the latter inoperative or prevent its being ridden
'by any unauthorised person.

page_text: For this purpose I provide an arm or lever pivoted to a sleeve or boss riveted
or otherwise securely fixed to one of the tubes or stays forming the back fork
of the machine. This arm or lever lies centrally along the said tube or stay when
the machine is unlocked or being ridden and is kept in this position by means
of a hooked catch engaging with the outer or free end of the arm or lever the
said catch being likewise riveted or rigidly attached to the tube or stay.
To the opposite tube or stay is brazed or otherwise rigidly fixed a block provided
with a lock and keyhole and formed with a slot for receiving the free end of the
arm or lever when turned into its locked position. The arm or lever is fitted
with a spring for keeping it with the assistance of the hooked catch in its unlocked
position along the tube of the fork and preventing it rattling from the motion of
the machine. It is also provided with an india-rubber sleeve or covering for
the same purpose and to prevent its contact with the spokes of the wheel.
In the accompanying drawings Figure 1 is a side view of a portion of a wheel
and its fork with my improved lock applied thereto and Figure 2 is a view at
right angles to the same. Figures 3 & 4 are opposite side views of the locking
block and Figure 5 is a cross section on the line of Figure 2. Figure 6 is an
elevation of a modified arrangement and Figure 7 is a cross section on line y y
of the same.
a is the arm or lever pivoted to the pin a riveted or otherwise fixed
to the sleeve brazed or rigidly attached to the stay c forming one arm of the
rear fork. d is the hooked catch fixed to the stay for engaging with the free
end of the lever a as shown in Figure 5 the lever a being also provided with the
spring a for keeping it in its unlocked position along the stay c and the india
rubber or other elastic covering a³ for preventing the contact with the spokes of
the wheel and injuring the same. e is the block fitted with a lock and a keyhole e¹
and brazed or rigidly fixed to the opposite tube or stay d¹ of the fork.
In this block is formed the slote for receiving the end of the lever a the
latter being slotted at a for engagement with the locking bolt in the block e.
When required to lock the wheel the lever a is turned into a horizontal position
as shown in dotted lines in Figures 2 & 5 its end entering the slot e² of the
block e to which it is locked by turning a key in the keyhole e. The lever thus
passes between two of the spokes and prevents the turning of the wheel and when
it is unlocked its spring a returns it to its position upon the tube or stay e under-
neath the catch as shown in the drawings.
Figures 6&7 show a modification in which a recessed or slotted block f is
brazed to the tube c of the fork within which recess lies a locking arm y pivoted
at g¹ so as not to protrude beyond the face of the block its end only extending a
short distance below the block so that the same may be caught hold of for turning
the said arm into its locked position where it is held in the locking block e as
in the arrangement before described. The army is acted upon by a spring h
fixed in the block so as to keep it in its closed or open position.
My improved locking device may be attached to the horizontal instead of the
vertical fork, of the rear wheel or it may be applied to the front fork of the
machine and by its special construction it is impossible to remove any portion of
it by means of a spanner or other tool by any unauthorised person wishing to
ride the machine with the object of stealing it.
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. In a locking device for cycles the combination of an arm pivoted to a sleeve
brazed or rigidly fixed to one side or stay of the wheel fork a spring and catch
for holding the said arm in its vertical or unlocked position on the said stay and a
slotted block provided with a lock and key brazed or rigidly attached to the other
stay of the said fork substantially as described and for the purposes specified.
2. In a locking device for cycles the combination of an arm or lever a a pin a¹ a
spring a elastic covering a³ slot at a sleeve b stays c c hooked catch block e

page_text: kev-hole e and slot all arranged and operating substantially as described and
for the purposes specified.
3. The modification as shown in and described with reference to Figures 6 & 7
of the accompanying drawings.
4. The improved locking device for cycles substantially as described and shown
in the drawings.
