page_text: I, JULIUS MOHS, of Brandenburg a/Havel, Prussia, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in cycle locking-devices for enabling
the handle-bar or steering-bar of a cycle to be fixed so as to render it impossible
to steer the cycle. By applying and using a locking-device of this kind, the
unauthorized use of the cycle is prevented.
Now this invention has for objects to enable such a locking-device to be
manipulated with ease and certainty even in the dark; to insure that the part of
the device by means of which it is attached to the cycle, will be covered over
when the device is in its locking position so that the device cannot be removed
from the cycle by unauthorized persons; and, finally, to insure that the unlocking
of the locking-device after it has been locked cannot be effected except by means
of a certain key.
All these features, which are all present in a device constructed so as to embody
the whole of this invention, serve to increase considerably the security of the
owner of the cycle, so that nobody who is not in possession of the key can use
the cycle. Such a device,, moreover, may be made so as to be very convenient
to handle and of small dimensions, so as to be inconspicuous.
An example of a locking-device constructed according to this invention is shown
in the accompanying drawings, in which
Fig. 1 is a horizontal central section of the locking-device with the parts in
the locking position,
Fig. 2 is a central horizontal section of the same with the parts in the unlocked
position, and
Figs. 3 and 4 are respectively an elevation and a plan of the key which is
required for securing the parts in the locking position.
As shown in Figs. 1 and 2, the action of the locking-device is such that, for
the purpose of locking, a bolt or pin b is inserted into a corresponding hole f
a tube. This tube, which may be the one by means of which the front wheel
is steered by the handle-bar, is surrounded by the tube of the frame of the
cycle, from which there projects laterally a hollow boss into which the locking-
device is screwed.
The locking device comprises a stud H which is screwed with one end into the
said boss, and may, as shown, be provided with annular grooves el e² and also
with one or more holes C. The device further comprises a casing a, mounted

page_text: movably on the stud H, and the bolt or pin b, which is fixed to the said casing
and which is capable of being moved with the casing a and is inserted in a
central perforation in the stud H.
The casing a is formed with a chamber in which is arranged a small coiled
spring which, when the bolt b is in its locking position (Fig. 1), holds a ball f
in the annular groove e¹ of the stud H, and, when the casing is drawn-back
(Fig. 2), holds the ball in the annular groove e² of the stud.
Opposite to the said chamber there may, as shown, be arranged in the casing a
second chamber which opens towards the outside and is formed with an internal
screw-thread, and in this second chamber there is inserted a short screw d that
is provided with a cavity o which is open to the outside. In this cavity there
be arranged a small stud o'.
may
The key z (Figs. 3 and 4) consists of a small tube which is slotted or slit at
one or both sides and is provided with a head and a ring, by means of which
it can be worn on a small chain by the owner of the cycle.
The mode of operation of the locking-device shown is as follows:-
--
When the casing a has been drawn outwards (Fig. 2), it has moved with it
the pin and has drawn it out of the hole in the ball f rests under the
pressure of the springs in the annular groove 2 of the stud H and thereby
secures the position of the casing against accidental movement.
With the parts in this position, the screw d is assumed to be screwed back
so that it is not in contact in any way with the stud H.
When the cycle is being secured against unauthorised use, the casing a is
slid on the stud H, towards the tube 2, into the position shown in Fig. 1, whereby
the pin is caused to enter the hole in the tube ; during this movement the
ball is moved back into its chamber, and is caused by the pressure of the spring
to enter the groove e¹. On now inserting the operating key z (which should
be elastic and is or may be compressed to some extent) into the cavity o of the
screw d, and on rotating the key so as to screw the screw into the locking-
device, the front end of the screw also enters the groove e¹ of the stud and
secures the locking-device in its locked position.
2
The small stud o¹ in the cavity o prevents unauthorised persons from being
able to screw the screw d back by the insertion of a nail or other article. Only
the key is suitable to be inserted into the annular space in the screw d and this
key when inserted in the compressed condition expands inside to such an extent
that, when rotated, it moves the screw d with it by friction. On being pushed
forward, the casing a has also, by means of its sleeve C¹ (when such is provided,
as shown), simultaneously covered the hole or holes C2 in the stud, and this
prevents the insertion into this hole or these holes of a screw spanner such as
would be necessary for removing the entire locking-device from the cycle. All
the outer surfaces of the locking-device being rounded so as not to afford any
hold for a spanner or pincers, all possibility of unscrewing the locking-device
from the cycle is practically excluded.
After the screw d has been screwed back (Fig. 2), the casing can be pushed
back again in order to withdraw from a³.
or
From what has been said, it will be seen that, for the purpose of locking
unlocking the locking-device, all that is necessary is to insert the small tubular
jamming key into the cavity of the screw d in order to screw the latter forwards
or backwards, and this can be easily done at any time, even in the dark.

page_text: I, JULIUS MOIS, of Brandenburg a/Havel, Prussia, in the Empire of Germany,
Manufacturer, 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 improvements in cycle locking-devices for enabling
the steering-bar of a cycle to be fixed SO as to render it impossible
to steer the cycle. By applying and using a locking-device of this kind, the
unauthorised use of the cycle is prevented.
Now this invention has for objects to enable such a locking-device to be
manipulated, with ease and certainty even in the dark; to insure that the part of
the device by means of which it is attached to the cycle, will be covered over
when the device is in its locking position so that the device cannot be removed
from the cycle by unauthorized persons; and, finally, to insure that the unlocking
of the locking-device after, it has been locked, cannot be effected except by means
of a certain key.
All these features, which are all present in a device constructed so as to embody
the whole of this invention, serve to increase considerably the security of the
owner of the cycle, so that nobody who is not in possession of the proper key can use
the cycle. Such a device, moreover, may be made so as to be very convenient
to handle and of small dimensions, so as to be inconspicuous.
An example of a locking-device constructed according to this invention is shown
in the drawings filed with my Provisional Specification, in which
Fig. 1 is a horizontal central section of the locking-device with the parts in
the locking position,
Fig. 2 is a central horizontal section of the same with the parts in the unlocked
position, and
Figs. 3 and 4 are respectively an elevation and a plan of the key which is
required for securing the parts in the locking position.
As shown in Figs. 1 and 2, the action of the locking-device is such that, for
the purpose of locking, a bolt or pin b is inserted into a corresponding hole of
a tube. This tube, which may be the one by means of which the front wheel
is steered by the handle-bar, is surrounded by the tube of the frame of the
cycle, from which there projects laterally a hollow boss into which the locking-
device is screwed.
The locking device comprises a stud H which is screwed with one end into the
said boss, and is preferably, as shown, provided with annular grooves e¹ and also
with one or more holes C. The device further comprises a casing a, mounted
movably on the stud H and the bolt or pin b, which is fixed to the said casing
and which is capable of being moved with the casing a and is inserted in a
central perforation in the stud H.
The casing a is formed with a chamber in which is arranged a small coiled
spring z, which, when the bolt b is in its locking position (Fig. 1), holds a ball f
in the annular groove e¹ of the stud H, and, when the casing is drawn back
(Fig. 2), holds the ball in the annular groove e² of the stud.
Opposite to the said chamber there may, as shown, be arranged in the casing a
second chamber which opens towards the outside and is formed with an internal
screw-thread, and in this second chamber there inserted a short screw d that
is provided with a cavity o which is open to the outside. In this cavity there
may be arranged a small stud o¹.

page_text: The key (Figs. 3 and 4) consists of a small tube which is slotted or slit at
one or both sides and is provided with a head and a ring, by means of which
it can be worn on a small chain by the owner of the cycle.
The mode of operation of the locking-device shown is as follows:-
When the casing a has been drawn outwards (Fig. 2), it has moved with it
the pin b and has drawn it out of the hole in ; the ball f rests, under the
pressure of the spring s, in the annular groove e² of the stud H and thereby
secures the position of the casing against accidental movement.
With the parts in this position the screw d is assumed to be screwed back
so that it is not in contact in any way with the stud H.
.r
When the cycle' is being secured against unauthorised use, the casing a is
slid on the stud H, towards the tube 2, into the position shown in Fig. 1, whereby
the pin is caused to enter the hole in the tube 3; during this movement the
ball is moved back into its chamber, and is caused by the pressure of the spring
to enter the groove el. On now inserting the operating key z (which should
be elastic and is or may be compressed to some extent) into the cavity o of the
screw d, and on, rotating the key so as to screw the screw d into the locking-
device, the front end of the screw also enters the groove e¹ of the stud and
secures the locking-device in its locked position.
2
The small stud o' in the cavity o prevents unauthorised persons from being
able to screw the screw d back by the insertion of a nail or other article. Only
the key is suitable to be inserted into the annular space in the screw d and this
key when inserted in the compressed condition expands inside to such an extent
that, when rotated, it moves the screw with it by friction. On being pushed
forward, the casing a has also, by means of its sleeve C₁ (when such is provided,
as shown) simultaneously covered the hole or holes C2 in the stud, and this
prevents the insertion into it or them of a screw spanner such as
would be necessary for removing the entire locking-device from the cycle. All
the outer surfaces of the locking-device being rounded so as not to afford any
hold for a spanner or pincers, there is practically no possibility of the unauthorized
unscrewing of the locking-device from the cycle.
After the screw d has been screwed back (Fig. 2), the casing can be pushed
back again in order to withdraw b from 3.
From what has been said it will be seen that, for the purpose of locking or
unlocking the locking-device, all that is necessary is to insert the small tubular
jamming key into the cavity of the screw d in order to screw the latter forwards
or backwards, and this can be easily done at any time, even in the dark.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:
1. A locking-device for cycles, comprising a stud H, a casing a, movably mounted
on the said stud, and a bolt or pin b which is fixed to the casing a and is inserted
in a central perforation of the stud H, the said locking-device being applied to
a cycle frame so that by moving the casing a the pin b can be caused to enter
a hole in that part of the cycle which is to be secured against use.
2. A locking-device according to the preceding claim, in which the stud H is
provided with two grooves e¹, e², and the casing a is provided with a movable
screw, which is adapted, on being screwed in and entering the groove el, to
secure the pin bin its locking-position in the part 3, whilst after screwing back
the screwd, the casing .can be moved so as to withdraw b out of 3.
3. A locking-device according to Claim 2, in which the screw d is provided with
a cavity o for the insertion of a tubular elastic key z with the object of screwing
the screw d forwards into the locking position (Fig. 1), or of screwing it back
for the purpose of unlocking the device.
4. A locking-device according to Claim 1, in which the stud H is provided at
its periphery with a hole C, or with a number of such holes, for the insertion

page_text: of the key for screwing the device firmly to a cycle, in combination with a sleeve-
like portion of the casing a, which sleeve-like portion will, in order to prevent
the locking-device from being unscrewed from the cycle, cover over the hole or
holes in the stud H when the casing is in the locking-position.
5. The improved cycle locking-device constructed, arranged, and operating as
hereinbefore described with reference to and shown in the drawings referred to.
Dated this 8th day of December 1898.
