PROVISIONAL SPECIFICATION.
An Improved Locking Apparatus for Bicycles, Tricycles, and other
Velocipedes.
JOHN TIMOTHY BROWN 5ª St. Marys Butts Reading, in the County of
Berks, Whitesmith, do hereby declare the nature of this invention to be as
follows:-
It consists of a small letter or figure locking device with a steel rod attached to
a spindle which works in the lock. The locking device is clamped to the fork or
otherwise attached thereto or to any convenient part of the machine.
This rod when in its normal position lies close to the fork. To lock the machine
lift rod to right angles and it becomes automaticaly fixed between the spokes of
the wheel and it also covers the screws or bolts by which lock is fixed to machine
to prevent lock being taken off.
To release the wheel it is necessary to know the combination of letters or
figures. Or may be made to open with a key.

An Improved Locking Apparatus for Bicycles, Tricycles, and other
Velocipedes.
JOHN TIMOTHY BROWN 5 St. Marys Butts Reading in the County of Berks
Whitesmith. I 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 means for locking wheels of velocipedes so as to prevent
their removal or use during the absence of the owner by an arrangement which
It consists of
may be permanently attached to the fork or framing of the vehicle.
a small tubular combination letter figure or key locking device with a spindle lever
and clamp by which it is clamped or otherwise attached to the front fork of a
safety bicycle or to any convenient part of machine. To lock machine it is
necessary to lift lever from a perpendicular to a horizontal position and it becomes
automaticaly locked between the spokes of the wheel but in the combination lock
it is necessary to move rollers. To unlock machine insert and turn key pull knob c
and turn lever down by side of fork, but in the combination lock place letters to
combination pull knob c and turn lever down by side of fork.
I will now describe the invention with reference to the accompanying drawings.
Like letters indicate like parts throughout the drawings. a in Fig. 3 is the
tubular case b and c in Fig. 3 is the knobs which covers the working parts to
exclude dust. din Fig. 3 is the spindle which works through the tubular case with
the lever e and knob c attached at one end and the locking pin f and washer g
attached at the other end, or in the key lock Fig. 5 the locking pin fis left out.
H in Fig. 3 is the coiled spring which bears one end against the washer
other end against rollers J and J, or in the key lock Fig. 5 against locking
washer G and projection t in tubular case a Fig. 5, the washer g' Fig. 5 is fixed
one end of spring H the other end of spring is fixed at projection t in
case a Fig. the washer in Fig. 5 turns on end of spindle and works in the slotted
on
the

page_text: end of tubular case a Fig. 5 as when the lock is unlocked the projection on
washer Fig. 5 is in the slot but the action of locking the lock pushes the
projection on washer out of the slot and it flys back into recess cut by side of slot,
the above mentioned coil spring is made to answer the double purpose of pulling
the lever into its locked position and turning the washer into recess, when the
key o can be taken out of lock.
The roller J' is cut down to receive roller J and is provided with a milled edge
to facilitate moving. The roller J is attached to and works on roller J, and knob b
is attached to roller J and each roller is slotted on the inside to pass the locking
pin f.
Fig. 1 shows a full size view of my invention attached to the front fork of a
safety bicycle in a locked position.
Fig. 2 shows a full size side view of my invention showing the manner of fixing
with the lever turned down by side of fork and the dotted lines show lever locked
between the spokes of the wheel and crossing the fixing screws to prevent them
from being drawn out when the lock is locked.
Fig. 3 shows a sectional plan with the tube a knobs b and c rollers J and J'
spindle d locking pin fcoiled spring H washer and lever E.
Fig. 4 is an enlarged view of tubular case a with one end notched such as m
and n to receive lever E the notch M is where lever fits when locked, the notch N
is where lever fits when in a normal position by side of fork the clamp K is fixed
to tubular case a and slotted such as R to receive lever E the clamp K' is drilled
and tapped to receive the fixing screws L, the notch N not being cut so deep as
notch M the rollers are not free to pass the locking pin fleaving the lock always
ready for use. The same arrangement applies to key lock Fig. 5 as when unlocked
the key such as o cannot be taken out of lock. I provide a coller on key to cover
keyhole such as P Fig. 5 to exclude dust when riding, or in place of the notches
mentioned above the casing may be made with a square recess and the spindle made
with a square end. It also shows the manner of stamping the combination on the
inside of clamp such a Q.
Fig. 5 shows my invention with key o and keyhole P in knob b and tubular case a
with knob off to show case slotted such as to receive the projection on locking
washer g² on end of spindle d in place of lettered rollers as described above.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is.
1. A wheel lock consisting of a tubular casing with slotted clamp as described.
2. A wheel lock the combination of a round spindle with a lever or bar attached
at one end and capable of being turned in the tubular casing whereby the locking
lever is placed between the spokes of the wheel and across the heads of the fixing
screws as herein described and set forth.
3. A wheel lock the combination of a round spindle fitted with one two or
more lettered rollers such as J and J' and coil spring such as H and washer and
locking pin such as fas herein described and set forth.
4. In a automatic wheel lock the combination of a spindle fitted with coiled
spring such as H and locking washer such as 9 Fig. 5 to be operated with key such
as o as herein described and set forth.
5. The combination and arrangements of parts consisting the complete wheel
lock substantially as herein described and set forth.
But take notice I do not claim anything in respect of the lettered rollers J and J'
the same being well known and in common use.
