PROVISIONAL SPECIFICATION.
An Improved Device for Preventing the Theft of Cycles.
I, KARL MEY, of 14-16, Waldhornstrasse, in the City of Karlsruhe, Grand
Duchy of Baden, in the Empire of Germany, Gentleman, do hereby declare the
nature of this invention to be as follows:
-
My invention has for its object an improved device for preventing the theft
of cycles, and it may be attached to any suitable part of the cycle frame. It
consists essentially in arranging an indicator or sign-board or like article in such
a manner that its operation is effected by the owner of the machine, so that when
the cycle is not in use the indicator or sign-board is displayed, and the public
are made acquainted with the fact that the owner is absent and tampering with
the machine thus prevented. In order however to prevent the use or removal
of the cycle by persons other than the owner where the machine has to be left
for some time in a lonely place where the sign board would not ensure the same
protection, additional cycle locks may be used as well as the present device;
such as locking the front or rear wheel, or the steering or driving mechanism
of the machine. I prefer to combine both the sign-board arrangement and the
locking device so that they can be operated simultaneously by the owner.
The mode of carrying my invention into effect is illustrated in the accompany-
ing drawings as follows;-
Figure 1 is a side elevation of the device attached to the steering head of
the cycle frame.
"
Figure 2 is a cross section on ay through Figure 1.
رو
Referring to the drawings:-The indicator or sign-board a is provided with
any suitable inscription (on one or both sides) such as " not to be stolen"
private or other word or words which would indicate to the public that the
machine was private property left temporarily. This sign-board a is pivotally
attached to the shell b, the said shell being formed integral with the steering
tube of the cycle frame. A sheath c is attached to the shell b in such a manner
that when the sign-board is swung down the sheath covers the board and the
sign becomes invisible.
In operating the device after using the cycle and when the owner wishes to
leave it, the latch d is pressed down releasing the board a and allowing it to
spring out into the position shown in the drawings, and this movement outwards
is effected by a spring e preferably arranged in torsion as shown. The board
is now secured by a padlock f locking corresponding openings arranged between
the sheath and board a to receive the arm of the padlock, so that when locked
the sign-board is secured in the position shown. When the sign-board takes
the position shown in Figure 1 a small corner piece al presses against a spring
ping attached to the steering head in such a manner that it enters the steering
tube and fixes it against rotation, in this way further securing the cycle against
theft or use in the absence of the owner.
When it is desired to again use the cycle the owner opens the padlock f and
turns the sign-board a down into the sheath and the said board is there

page_text: automatically locked by the catch or latch dwhile simultaneous with this action
the pin g springs back releasing the steering head. It is of course evident that
the padlock is arranged to open only by means of a particular key carried
by the owner, and it is further evident that a puzzle or letter lock could be
employed for the same purpose 'without departing from the subject of the present
invention.

An Improved Device for Preventing the Theft of Cycles.
I, KARL MEY, of 14-16, Waldhornstrasse, in the City of Karlsruhe, Grand
Duchy of Baden, in the Empire of Germany, Gentleman, 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 has for its object an improved device for preventing the theft
of cycles, and it may be attached to any suitable part of the cycle frame. It
consists essentially in arranging an indicator or sign-board or like article.in such
a manner that its operation is effected by the owner of the machine, so that when
the cycle is not in use the indicator or sign-board is displayed and the public
are made acquainted with the fact that the owner is absent and tampering with
the machine thus prevented. In order, however, to prevent the use or removal
of the cycle by persons other than the owner where the machine has to be left
for some time in a lonely place where the sign-board would not ensure the same
protection additional cycle locks may be used as well as the present device,
such as locking the front or rear wheel, or the steering or driving mechanism
of the machine.. I prefer to combine both the sign-board arrangement and the
locking device so that they can be operated simultaneously by the owner.
"
The mode of carrying my invention into effect is illustrated in the drawings
accompanying the Provisional Specification. In these drawings:-
Fig. 1, is a side elevation of the device attached to the steering head of the
cycle frame.

Fig. 2, is a cross section on a through Fig. 1.
Referring to the drawings:-The indicator or sign-board a is provided with
any suitable inscription (on one or both sides) such as "not to be stolen
private or other word or words which would indicate to the public that the
machine was private property left temporarily. This sign-board a is pivotally
attached to the shell 6, the said shell being formed integral with the steering
tube of the cycle frame. A sheath c is attached to the shell 6 in such a manner
that when the sign-board is swung down the sheath covers the board and the
sign becomes invisible.
In operating the device after using the cycle and when the owner wishes to
leave it, a latch & consisting of a spring d¹ fixed at its end and provided with
an inclined projection at its free end is pressed down the projection d
releasing the board a and allowing it to spring out into the position shown in
the drawings, and this movement, outwards is effected by a spring e preferably
arranged in torsion as shown. The board is now secured by a padlock f.locking
corresponding openings arranged between the sheath c and board a to receive
FTC

page_text: the arm of the padlock so that when locked the sign-board is secured in the
position shown. When the sign-board takes the position shown in Fig. 1, a
small corner piece at presses against a pin or bolt g which is adapted to slide'
against a spring in a socket g₁ attached to the steering head in such a manner
that it enters a hole in the steering tube when the board a is in its upward
position and fixes said tube against rotation, in this way further securing the
cycle against theft or use in the absence of the owner.
When it is desired to again use the cycle the owner opens the padlock f and
turns the sign-board a down into the sheath c and the said board is there
automatically locked by the catch or latch while simultaneous with this action
the pin g is forced back by its spring releasing the steering head. It is of course
evident that the padlock f is arranged to open only by means of a particular
key carried by the owner, and it is further evident that a puzzle or letter lock
could be employed for the same purpose without departing from the subject
of the present invention.
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.) An improved device for preventing the theft of cycles consisting of an
indicator or sign-board a provided upon the cycle frame but not capable of
being taken off, having upon it an inscription such as
66 not to be stolen,' or such
like, and a sheath c fixed on the cycle frame or forming a part thereof for the
reception of the indicator or sign-board when not in use, the latter being fastened
in its open position by a lock or other suitable means, substantially as and for
the purpose hereinbefore described.
2.) An improved device for preventing the theft of cycles as specified in
Claim 1, in which a pin or bolt such as g is caused to engage with the steering
tube or other part in a manner for the purpose and substantially as described.
