Improvements in or relating to Fixing or Locking Devices for Cycles.
A communication by the Firm of GEORG BEISSBARTHI, vorm. FRIEDRICH LOOS, of
46, Gostenhofer Hauptstrasse, Nuremberg, in the Empire of Germany, Metal
Goods Manufacturers.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, of 6, Lord Street, Liverpool, & 6, Bank Street, Manchester,
both in the County of Lancaster, 118, New Street, Birmingham, in the County
of Warwick, & 322, High Holborn, in the County of Middlesex, Civil Engineer,
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 has for its object an improved fixing or locking device for
cycles. It consists essentially in a strip-spring which lies close against the lower
frame bar or tube, being arranged pivotally on its central axis at the point of
juncture where the steering socket of the front wheel fork tube meets or
encounters the lower.frame bar or tube, said spring carrying at its end an adjust-
able pin, which latter in a given position of the spring may be inserted into two
openings corresponding with one another in the steering socket and the front
wheel fork tube and thus both parts be fixed one against the other.
The improved fixing device is shown in Figures 1 to 5 of the accompanying
drawings, Figure 1 being a side view of the whole arrangement, together with
the front wheel of a bicycle and Figures 2 to 5 detail views.
At the place where the steering socket 1 of the front wheel fork tube 2 meets
or encounters the lower obliquely inclined frame bar or tube 3, there is a strip
spring 4, having its centre pivotally mounted on the axis of a screw 5 inserted
in the said frame bar or tube 3 Figures 3 to 5. By the elasticity of the spring
both of its ends are pressed against the outside of the bar or tube 3 so that in the
position of the spring shown in Figures 3 to 5 a stud 6 located on one of its ends
engages in an opening 7 of the frame bar or tube 3. At the other end which is
strengthened by means of a flange or socket 8 a pin 9 is located, provided with
a head 10, and corresponding, in the above mentioned position of the strip spring,
with an opening 11 in the steering socket 1. When the front wheel 12 assumes
the straight position shown in Figure 1 the opening 13 formed in the fork
tube 2 comes to lie in the same axis as the opening 11 and the pin 9, so that the
latter engages in both openings 11 and 13 by the pressure on the head 10
(Figure 5) and thus the fork tube 2 is fixed against the steering socket 1.
In order to loosen the connection, the pin 9 is drawn upwards by means of the
head 10, a projection 14 formed on the pin encountering a correspond-
ing projection on the flange or socket 8, and thus preventing the pin
slipping out of the flange. If the spring be then turned 180°, the stud 6
snaps into the opening 11 of the steering socket and holds the spring fast in this
position (Figure 4) whilst the pin 9 now faces the opening 7, and may be inserted
in the latter.

page_text: The fixing or locking device hereinbefore described in addition to its simplicity
is characterised by its capability of being applied subsequently without difficulty
to any cycle or wheel, and it also affords the advantage, as shown in Figure 2, that
the opening 11, uncovered on the turning back of the spring, allows of a
lubrication of the lower steering bar bearing 15.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claim is:
A fixing or locking device for cycles, consisting of a strip spring (4) resting
against the frame bar and pivotally mounted on its central axis (5) being
provided at one end with a stud (6) engaging in an opening (7) and at the other
end with an adjustable pin (9) which engages into two openings (11 & 13) of
the spring socket (1) and of the fork tube (2), which latter openings correspond
with one another when the front wheel (12) is in a straight position, and thus
both parts are fixed as regards one another, substantially as hereinbefore described
and shown.
