Improvements in Head-locks for Cycles.
1, MARTIN DIEDERICH RUCKER, of Humber & Co. Ltd., 32, Holborn
Viaduct, in the County of Middlesex, Managing Director, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a head-lock for cycles, the object being to fix the
steering head so that the machine cannot be steered or the head turned, a particu-
larly useful attachment to a safety bicycle when it is desired to stand it against
a wall or similar support.
In carrying out my invention I employ what 1 may term a hollow cottar or
wedge passed through a portion of the barrel or frame-work of the machine and
fitting around the tube forming the top of the front fork or steering, head so that
when this hollowed cottar is pressed up against the tube which turns with the
handle and the steering wheel it prevents the tube from turning and thus locks the
handles and steering wheel rigidly to the frame.
Various means may be employed for applying the pressure, as for example a nut
screwed on to the smaller end of the cottar or the latter may be eccentrically
formed so that when turned by means of a convenient handle or the like it will
bear upon the tube.
Although for convenience I prefer to make the cottar tapered it may be made
parallel if required and may take the form of a flat wedge instead of a round or
other shaped cottar.

Improvements in Head-locks for Cycles.
I, MARTIN DIEDERICH RUCKER of Humber & Co. Limited, 32 Holborn
Viaduct, in the County of Middlesex, Managing Director, 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 a head-lock for cycles, the object being to fix the
steering head so that the machine cannot be steered or the head turned, a particu-
larly useful attachment to a safety bicycle when it is desired to stand it against
a wall or similar support.
The invention will be best understood by reference to the accompanying drawings,
in which
Figure 1 is a horizontal section through a cycle steering head provided with one
form of lock constructed according to my invention, and
Figure 2 is a vertical section showing another form of the head lock, and,
Figure 3 is a view similar to Figure 2 of a modified form.
Like letters indicate like parts throughout the drawings.

page_text: In carrying out my invention in the inauner shown in Figure 11 employ a recessed
cottar or wedge A passed through a portion of the barrel or frame-work B of the
machine and fitting upon the tube C forming the top of the front fork or steering
head so that when this recessed cottar A is pressed up against the tube C which
turns with the handle and the steering wheel (not shown in the drawing) it prevents
the tube C from turning and thus locks the handles and steering wheel rigidly to
the frame.
Various means may be employed for applying the pressure, as for example a
nut D screwed on to the smaller end of the cottar A or the latter as shown in
Figure 2 may take the form of a shaft provided at one part with an eccentric
cam A' so that when turned on its axis by means of a convenient handle or the like
the eccentric will bear upon the tube C.
Although for convenience I prefer to make the cottar A shown in Figure 1
tapered it may be made parallel if required and may take the form of a flat wedge
instead of a round or other shaped cottar... I prefer however to recess the cottar as
shown lest if Hat it should damage or flatten the tube C.
If desired, as shown in Fig. 3 a stop A² may be placed so as to engage with a
corresponding recess or slot C¹ in the tube C for the purpose of fixing the steering
,head with the wheels in the same plane.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A head lock for cycles comprising a recessed cottar such as A. and,means
such as a nut D for tightening it against the steering head substantially as described
., and; illustrated in Figures 1 and 2 of the accompanying drawings.
2. Locking the steering head of a cycle by a cottar such as A pressed against
the movable member of the head.
3. A head lock for cycles comprising a shaft such as A. having an eccentric or
cam such as A and capable of being turned on its axis to tighten the cam against
the steering head substantially as described and illustrated in Figure 2 of the
accompanying drawings.
