page_text: I WILLIAM WIGGETT of No. 28 Freegrove Road, Islington in the County of
Middlesex, Carpenter, do hereby declare the nature of my said invention for "AN
IMPROVED ARRANGEMENT FOR LOCKING THE WHEELS OF VELOCIPEDES WHEN NOT
IN USE to be as follows:-

The object of my invention is to make a velocipede unrideable pro. tem. at the
will of the rider, so as to render it less liable to be stolen. To effect this I mount
on some fixed part of the machine a small lock, the bolt of which takes into one
of a series of holes drilled in the hub of one of the driving wheels, or its
equivalent, so that the wheel may be locked to the frame of the machine,. & so
prevent it being ridden.
It will be understood that the construction of my "Protector Lock" will
require to bo varied to suit the various types of Velocipedes to which it may be
fitted; for instance, in fitting it to a machine with two large wheels, only one of
which is a
"driver" I clamp or otherwise fix my lock to the stud axle of the
non-driving wheel & drill a series of holes to receive the bolt of the lock, in the
hub of the non-driving wheel, or fix a plate provided with the necessary holes to
the hub, so as to prevent the wheel revolving. Again in fitting it to a double-
driving machine with a through axle, to which one of the driving wheels is fixed,
I fit the lock on to the axle, & tho plate, to receive the bolt of the lock, to the
frame, so as to prevent the axle revolving. Or again in fitting it to a bicyclo I fit
the lock on to the inner side of one of the cranks & fix the plate to receive the bolt
on to the fork, so as to lock the wheel to the fork.

The form of lock that I prefer to use is that known as a latch lock; i,e, a lock
in which the locking is effected by the aid of a spring without the use of a key,
but instead of making the bolt to work automatically, I manipulate it by pressing
down a small spring lever which frees the bolt & so locks the machine, the unlocking
being effected by a key in the usual manner.
I construct my lock as follows; I mount the locking plate on the fulcrum pin
& connect it to the sliding bolt in any approved manner. A spring bears against
the locking bolt to press it forward. On the locking plate is a projection, against
which the beard of the key bears, and acting upon it draws back the sliding bolt.

page_text: Mounted in a suitable position is a small bell crank lever, at one end of which is a
projecting piece which engages with a recess cut on the locking plate, when the
sliding bolt is drawn back by the use of the key, & held there, a spring being
used to keep it in contact. Opposite the end of the other arm of the bell crank is
a small hole in the case of the lock, through which by pressing down the end of
the bell crank, the locking plate is released, & the sliding bolt shot forward by
the spring bearing against it. To unlock the lock the key is used as before
stated.

I WILLIAM WIGGETT of No 28 Freegrove Road, Islington, in the County of
Middlesex Carpenter, do hereby declare the nature of my said invention for "AN
IMPROVED ARRANGEMENT FOR LOCKING THE WHEELS OF VELOCIPEDES WHEN NOT
IN USE" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of my invention is to make a Velocipede unrideable pro. tem. at the
will of the rider, so as to render it less liable to be stolen. To effect this I mount
on some fixed part of the machine a small lock the bolt of which takes into one
of a series of lioles drilled in the hub of one of the driving wheels or its equivalent,
so that the wheel may be locked to the frame of the machine and so prevent it
being ridden. It will be understood that the construction of my "Protector lock"
will require to be varied to suit the various types of Velocipedes to which it may
be fitted for instance in fitting it to a machine with two large wheels only one of
which is a driver I fix my lock to the stud axle of the non-driving wheel and drill
a series of holes to receive the bolt of the lock in the hub of the non-driving wheel,
or fix a plate to the hub provided with the necessary holes to receive the bolt of
the lock so as to prevent the wheel revolving. Again in fitting it to a double
driving machine with a through axle to which one of the wheels is fixed I fit the
lock on to the axle and the plate to receive the bolt of the lock, to the frane so, as
to prevent the axle revolving, or again in fitting it to a bicycle I either fit the lock
on to the innerside of one of the cranks and fix the plate to receive the bolt on to
the fork, or I fix the lock to the case of the bearing at the bottom of the fork and
drill a series of holes in one flange of the hub to receive the bolt of the lock so as
to lock the wheel to the fork.
The form of lock I prefer to use is that known as a latch lock i.c. a lock in which
the locking is effected by the aid of a spring without the use of a key, but instead
of making the bolt to work automatically I manipulate it by pressing down a small
spring lever which frees the bolt and so shoots the bolt of the lock and locks the
machine, the unlocking being effected by a key in the usual manner. I construct
iny lock as follows, I mount the locking plate on the fulcrum pin and connect it to
the sliding bolt in any approved manner, a spring bears against the locking bolt to
press it forward; on the locking plate is a projection against which the beard of
the key bears and acting upon it draws back the sliding bolt. Mounted in
a suitable position is a small bell crank lever, at one end of which is a projecting
piece which engages with a recess cut on the locking plate when the sliding bolt is
drawn back by the use of the key, and holds it there; a spring being used to keep
it in contact. Opposite the end of the other arm of the bell crank is a small hole
in the case through which a stop fixed to the end of the bell crank lever protrudes,
by pressing down which the locking plate is released and the sliding bolt shot
forward by the spring bearing against it. To unlock the lock the key is used as
before stated.

page_text: In order that my invention may be fully understood I will more particularly
describe it by the aid of the accompanying drawings on which similar parts aro
marked with like letters of reference.
Figs 1 and 2 are side elevations of my lock (with the cover plate removed) the
latter showing the locking bolt shot, and the former withdrawn. Fig 3 is an end
elevation of the lock showing it fixed to the axle of a machine. Fig 4 shows the
application of the lock to a tricycle with a non-driving wheel mounted on a fixed
stud axle, the wheel being locked to the axle.
Fig 5 shows its application to a double driving tricycle in which the axlo
revolves, the axle being locked to the frame of the machine. Fig 6 shows its
application to a bicycle, the lock being fixed to the case of the bearing attached to
the fork, and locks the wheel to the fork.
"
Referring to these figures A designates the lock the component parts of which
are; a..the locking plate, b. the locking bolt, c. the bell crank lever, d. the locking
button or stop, c. the bell crank lever spring, the locking bolt spring, and g. the
fulcrum or key pin.
The lock is shown without any wards as these may be arranged according to the
quality of the lock it is proposed to uso; it will also be obvious that the whole
construction of the lock may be improved by constructing it on the lever principle.
The lock is provided with a cylindrical clip by which it may be fixed to the axle
as shown by Fig 3 or where it is not possible to get at the end of the axle to slip
the clip into position, one encircling only a portion of the axle is used. X designates
the frame of the machine, Y the hub of one of the wheels, and Z the axle.
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
First. A lock constructed as and for the purpose herein before described and
shown, or any mere modification thereof.
Secondly. Fixing a lock to a velocipede for the purpose of locking some moving
part of the machine to some fixed part of the same, as hereinbefore described and
shown.
