I, HENRY VANDER WEYDE of 182, Regent Street, W. Artist and Electric
Light Photographer, do hereby declare the nature of my invention to be as
follows:-
My invention relates to improved means of locking the steering fork of a
bicycle or the like in such position as to prevent the machine being easily wheeled
away and it has for its object to enable the locking to be effected quickly by the
mere pressure of the hand and in such a way that it cannot be unfastened without
the aid of the proper key, the steering fork when thus locked being so turned that
the wheels will only run in a very small circle so that forward progress on the
wheels is impossible.
The improved fastening consists of a bolt capable of being made to enter holes
in the head and steering fork spindle when those holes coincide, said bolt being
normally held out of engagement by a spring and in the combination therewith of a
lock in the nature of a padlock which when caused to bear on the spring forces
the bolt into the holes so as to render the steering fork immovable immediately
the fork is so turned that the holes coincide.
The lock may be an ordinary padlock body but instead of having a bow it is
hinged to and snaps into engagement with lugs on a collar clamped around the
steering fork head upon which the spring bolt is mounted in position to be pressed
on and covered by the lock body when the latter is in the locked position. The
collar is made in halves hinged together to enable it to be readily clasped around
the steering fork head the hinge being concealed and the collar being secured by a
screw or other fastening which is likewise covered by the lock body when in the
locked position so that tampering with the fastening is impossible.

Improved means of LOCKing Bicycles and the like.
I, HENRY VANDER WEYDE of 182, Regent Street, W. Artist and Electric
Light Photographer, 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 improved means of locking the steering fork of a bicycle
or the like in a fixed position so as to prevent the machine being easily wheeled
away by a thief and it has for its object to enable the locking to be effected quickly
by the mere pressure of the hand and in such a way that it cannot be unfastened
without the aid of the proper key.

page_text: Reference is to be had to the accompanying drawings forming part of this
specification in which
Figure 1 is a side view and Figure 2 a top view shewing the device in the locked
position.
Figure 3 is a side view shewing the lock in the unfastened position.
Figure 4 is a rear view of the collar with the lock removed.
Figure 5 is a perspective view of the two halves of the collar separated and
detached.
Figure 6 is a perspective view of the lock detached.
Figure 7 is a section shewing the locking pin as carried by a spring instead of
by the lock body.
The improved fastening consists of a bolt or pin a capable of being made to
enter holes bc in the head B of the frame and in the steering fork spindle C when
those holes coincide, said bolt or pin being normally held out of engagement with
the hole c. The lock A may be an ordinary padlock body but instead of having
a bow it is hinged at d to a collar D D' and snaps into engagement with a lug e
fixed on the part D of said collar. The collar is made of two halves DD' adapted
to be clamped tightly around the head B of the frame forming the socket in which
the steering fork spindle turns, the two halves being detachably hinged together
by interlocking hooked ends ff to enable it to be readily affixed in position, the
collar being secured by a screw g passed through a lug g' on the one part D and
screwing into a hole tapped in the other part D₁ the direction of the screw being
such as to draw the parts tightly together. Instead of hinging the parts D D
detachably by the. interlocking hooked ends f, they may be permanently hinged
together, provided that the hinge pin is so inserted or secured as not to be
removable from the outside. The halves of the collar are provided with flanges
between which the lock A is hinged and which enclose a recess in which the lock
body is partly received when in the locked position so that the flanges cover the
joints. In this recess the lug e and the fastening screw 9 are situated so as to be
covered by the lock body when the latter is in the locked position in order that
tampering with the fastening shall be impossible.
The collar has a guide hole i for the pin a and this hole coincides with the hole b
in the socket. The hole c in the steering fork spindle may be in such position
that it will also coincide with the hole 6 when the steering wheel is straight or
when it is turned or there may be several such holes c in the spindle so as to
enable the spindle to be locked when the wheel is in the one or other position
at will.
In Figures 1 to 6 the locking pin a is carried by the lock body A and is held
retracted by the weight of the lock, as shewn in Figure 3, but in Figure 7 the
pin a is attached to a spring k fixed in the recess of the collar the pin being
normally held retracted from engagement with the hole c in the spindle by the
spring, except when pressed upon by the lock body.
The internal mechanism of the lock is of the ordinary kind, adapted to snap into
locking engagement with the hooked lugs e e, preference being given to a lock of
the well known Yale type.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The herein described means of locking the steering fork of a bicycle or the
like, consisting of a locking pin or bolt adapted to enter holes in the socket and
spindle but normally retracted therefrom, in combination with a lock body hinged
to a collar and adapted to enter into locking engagement therewith and thereby to
force the locking pin or bolt into engagement with the steering fork spindle
substantially as specified.
2. The herein described locking device constructed substantially as specified,
the lock body being adapted to cover the fastening connecting the two parts of the

page_text: collar and to enter a recess in which the spindle locking pin and the snap hook
which enters the lock are situated so that tampering with the fastening is prevented
as described.
