page_text: I, JOHANNES EMIL CAESAR STALLMANN, of Neumünster, in the Province of
Schleswig Holstein, Prussia, in the Empire of Germany, Organist, do hereby
declare the nature of this invention to be as follows:-
This improved cycle-lock has reference to that class of lock, by which the
rotatable handle-bar tube can be locked to the head socket tube, in order to
thereby prevent the handle bar tube from being rotated and to consequently
prevent riding.
This improved cycle lock is provided between two guide rings with a rotatable
ring which carries a locking bolt with locking spring and a slide.
When the bolt occupies the locking position, it is in engagement with two
openings, one in the handle bar tube and the other in the head socket tube
and retains the handle bar tube locked to the said head socket tube. The slide
is retained by the bolt by means of an engaging spring which is adapted to engage
behind a projection of the rotatable ring, and the lock cannot therefore be
opened by unauthorized persons not in possession of the proper key.
If, on the contrary, by the aid of a key which may be varied in form or
construction for each lock, the engaging spring is moved forward behind the
projection and if the slide is turned against the bolt by means of the outer
knob or handle the said slide by embracing a shoulder of the bolt with its fork
shaped end forces the bolt back out of the two openings of the aforesaid tubes.
The handle bar tube then admits of being freely turned within the head socket
tube.
In order to prevent the lock from again returning into the tube openings after
the slide has been released and returned by a retracting spring to its original
position, the ring, prior to this releasing action is slightly turned, so that the bolt
no longer lies opposite the opening of the head socket tube. The lock is thus
open and the handle bar tube can be turned within the head socket tube.
The above described cycle lock is so constructed as to admit of being made as
a separate part and of being arranged on any velocipede. Owing to the fact,
that the lock-ring can be rotated and the bolt he moved out of the neighbourhood
of the tube-openings, the handle bar tube is absolutely prevented from being
unintentionally locked to the neck tube during riding.

page_text: I, JOHANNES EMIL CAESAR STALLMANN, of Neumünster, in the Province of
Schleswig Holstein, Prussia, in the Empire of Germany, Organist, 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 improved cycle-lock has reference to that class of lock, by which the
rotatable handle-bar tube can be locked to the head socket tube or neck tube
of the frame, in order to thereby prevent the handle bar tube from being rotated
and to consequently prevent riding.
In order that my invention may be more fully understood by one skilled in the
art to which it appertains I will now proceed to describe the same in detail and
for that purpose shall refer to the accompanying drawings, in which :
Figure 1 is a side elevation of my improved cycle lock when attached to the
socket or neck tube of the cycle frame, and in its unlocked position so that the
handle bar tube may be freely turned within the neck tube; only so much of
the frame itself being shown as is necessary for a clear understanding of the
device.
Figure 2 is a horizontal section through the cycle lock when its bolt occupies
the locking position; in this figure the cycle frame or the cycle respectively
is shown so as to be at right angles to the position of the cycle frame illustrated
in Figure 1.
Figure 3 is a similar view to Figure 2 showing the locking bolt forced
back out of the openings of the handle bar tube and neck tube.
Figure 4 is a plan of the cycle lock as it appears after the removal of the
upper guide ring and after the rotatable ring with the locking bolt has been
turned in the position of use; the position of the cycle lock shown in Figure 4
corresponds to that shown in Figure 1, the cycle frames however being at right
angles to each other.
Figure 5 is an elevation, and
Figure 6 a horizontal section of the slide piece for disengaging or unlocking
the locking bolt.
Figure 7 is a detailed plan of the upper guide ring.
The improved cycle lock is arranged between two guide rings cc and consists
of a rotatable ring d which carries a locking bolt e with locking spring e¹ and a
slide f. The guide rings c c consisting each of two halves are clamped upon
the neck tube 6 of the cycle frame 12.
When the bolt occupies the locking position (Figure 2), it is in engagement
with two openings, one in the handle bar tube a and the other in the head
socket tube b and retains the handle bar tube locked to the said head socket
tube. The slide f is kept away from the bolt by means of a spring f' which
is adapted to engage behind a projection or nose of the rotatable ring d, and
the lock cannot therefore be opened by unauthorized persons not in possession
of the proper key.
If, on the contrary, by the aid of a key g which may be varied in form or
construction for each lock and which is to be inserted into the key hole g¹, the
spring is pushed beyond the projection and if the slide f is turned towards
the bolt e by means of its outer knob or handle f² (Figure 3) the said slide f by
embracing the bolt e with its fork shaped end (Figures 5 and 6) and acting
against a shoulder of the said bolt forces the latter back out of the two openings

page_text: of the aforesaid tubes a and b. The handle bar tube a then admits of being
freely turned within the head socket tube b.
In order to prevent the bolt e from again returning in the tube openings
after the slide has been released and returned by a retracting spring to its
original position, the ring d, prior to this releasing action is slightly turned, so
that the bolt no longer lies opposite the opening of the head socket tube b
(Figure 4). The lock is thus open and the handle bar tube a can be turned
within the head socket tube b.
The above described cycle lock is so constructed as to admit of being made as
a separate part and of being arranged on any velocipede. Owing to the fact,
that the lock-ring d can be rotated and the bolt e be moved out of the neighbour-
hood of the tube-openings, the handle bar tube a is absolutely prevented from
being unintentionally locked to the neck tube during riding.
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. In a cycle lock the combination of a locking ring (d) rotatably attached
to the neck tube of the cycle frame, a locking spring actuated bolt (e) and a
disengaging slide (f f¹ f²) for the latter substantially as and for the purpose
set forth.
2. The improved cycle-lock for rigidly coupling or connecting the handle
bar-tube and the neck tube with each other constructed, arranged and operating,
substantially as hereinbefore described with reference to and shown in the
drawing.
