Improvements in Steering Locks for Cycles.
I, GEORGE GILBERT, Director of The Centaur Cycle Co., of West Orchard
Works, Coventry, in the County of Warwick, Cycle Manufacturers, do hereby
declare the nature of my said invention to be as follows :-
This invention has for its object improvements in steering locks for cycles which
is very simple in action and is readily adaptable to any kind or make of machine.
It also has the advantage that when unlocked it is almost impossible to become
locked by accident when not so required.
In carrying my invention into effect I provide a piston bolt which is contained
within a socket the whole heing mounted upon a clip or band which fits around the
steering socket. A bolt hole is formed in the steering socket, a corresponding bolt
hole being provided in the steering spindle. A collar is formed upon the bolt and
a coiled spring is provided which takes a seating on one end against a shoulder in
the piston socket and at the other against the collar the tendency of the spring
being to press the bolt into a locking position. The piston is made to turn in its
socket and around the neck of the socket four slots or notches are provided,
corresponding pins or studs being provided upon the piston to engage with same.
One pair of the slots are sufficiently deep to allow the bolt to be forced home by the
spring for locking purposes-while the other pair of slots are only sufficiently deep
to retain the bolt clear of the steering spindle the full compressing force of the
coiled spring being in this case brought to bear upon it so that any possibility of
the studs being jerked from their seating and the bolt becoming engaged with the
steering spindle is practically obviated.
The clip or band for securing the locking arrangement to the steering socket
formed of a spring band and is provided with snugs and set screws for its easy
attachment and for ready accomodation to any variation in size of the steering
socket. A suitable head is provided to the piston so that for unlocking it is only
necessary to withdraw the piston against the compression of the spring and give it
a half turn so as to bring the studs over the reverse slots where they are retained
by the action of the spring as before described.

I, GEORGE GILBERT, Director of The Centaur Cycle Co. of West Orchard
Works, Coventry in the County of Warwick, Cycle Manufacturers, do hereby
declare the nature of my said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
1..
This invention bas for its object improvements in steering locks for cycles which
are very simple in action and are readily adaptable to any kind or make of machine.

page_text: My lock also has the advantage that when uhlocked it is almost impossible to
become locked by accident when not so retjuired.
In carrying my invention into effect provide a piston bolt which is contained
within a socket the whole being mounted upon a clip or band which fits around the
steering socket. A bolt hole is fornied in the steering socket, a corresponding bolt
hole being provided in the steering spindle. A collar is formed upon the bolt and
a coiled spring is provided which takes a seating on one end against a shoulder in
the piston socket and at the other. against the collar the tendency of the spring
being to press the bolt into a locking position." The 'piston is made to turn in its
socket and around the neck of the socket four slots or notches are provided,
corresponding pins or studs being provided upon the piston to engage with same.
One pair of the slots are sufficiently deep to allow the bolt to be forced home by
the spring for locking purposes-while the other pair of slots are only sufficiently
deep to retain the bolt clear of the steering spindle the full compressing force of
the coiled, spring being in this case brought to bear upon it so that any possibility
of the studs being jerked from their seating and 'the bolt becoming engaged with
the steering spindle is practically obviated.
The clip or band for securing the locking arrangement to the steering socket is
formed of a spring band and is provided with snugs and set screw for its easy
attachment and for ready accomodation to any variation in size of the steering
socket. A suitable head is provided to the piston so that for unlocking it is only
necessary to withdraw the piston against the compression of the spring and give it
a quarter turn so as to bring the studs over the reverse slots where they are
retained by the action of the spring as before described.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which my
device is clearly illustrated and which will enable any person conversant with such
matter to adapt it.
Figure is a broken off side elevation of the steering socket A and spindle B
with my locking device E attached thereto.
Figure 2 is a section through the steering socket A and spindle B showing the
locking device E in plan.
Figure 3 is a horizontal section of the locking device E embracing the
socket A.
Figure 4 is a front view of the notched face of the neck e¹ of E with the bolt e
taken away.
Figure 5 is a broken off elevation of the hinged part and the fastening
screw e in detail.
My lock consists of the main or front portion E which is a stamping or casting
fastened to a spring which is secured to E at el so that when the screw e is
turned outwards as shown at Figure 5 the lock may be applied to the spindle or
taken from it by springing the band e. "When it is on the socket A as shown by
the three first figures the screw e is in the position as there shown. To take the
lock off the spindle, e is unscrewed until the shoulder e is out of the socket when it
will turn upon e8 sideways through the slot which allows the screwed part e to
pass. The inside of e is of course tapped to suit the screw e. Now the locking
device when upon the spindle has in its main portion E with the piston bolt e²
mounted therein and its locked position as seen at Figure 2, that is to say the
point e3 of the bolt is forward through the holes a¹ of the socket A and b' of the
spindle B and the spindle is therefore locked. The bolt is held well through
the holes a and b by the spring e¹s which bears against the piston or collar e¹ the
cross'pin e falling now into the deeper slots e of the neck e. In Figure 3 the
bolt is unlocked and the cross pin ele is there in the shallow slots e12 which do not
allow the bolt to penetrate the socket A or spindle B.
It will thus be seen that my device is very simply applied to the spindle socket of
any existing machine and just as easily taken off and that its action is absolutely
certain and the parts secure in either the locked or unlocked position.

page_text: 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:
-:
The improvements in steering locks for cycles consisting of the band to embrace
the socket A fitted with its spring bolt e and screw e mounted and acting-
substantially as herein set forth and as shown upon the drawings by Figures 1 to 5
inclusive.
