PROVISIONAL SPECIFICATION.
Improved Means for Securing Lamps to Bicycles, Tricycles, and
other Vehicles, and for such like purposes.
We WILLIAM STEWARD and HARRY CURETON, trading as Cureton and
Steward both of Staniforth Street Lamp Works Staniforth Street Birmingham
in the County of Warwick, Manufacturers do hereby declare the nature of this
invention to be as follows:-
:-
This invention relates to the above or any like purposes, and consists in attaching.
to the back of the lamp and also to the socket or slide that fits on to the lamp
bracket a lock-plate and lock which may be in any suitable position upon the lock
plate.
At the lower end of the lock plate is hindged or otherwise suitably connected
a catch of a peculiar formation being bent back to form a catch piece and tongue
and having a slot or hole cut therein into which the bolt of the lock shoots.
When the lamp is locked on to the machine the hindged catch piece and tongue
is turned back underneath the bracket that carries the lamp the back portion of
the catch forms a shoulder and bears against the underside of the lamp bracket
the tongue portion of the catch coming forward horizontally through a slot in the
lock plate is secured by the lock and the lamp cannot be removed from the machine
until released by the unlocking of the catch."

COMPLETE SPECIFICATION.
Improved Means for Securing Lamps to Bicycles, Tricycles, and
other Vehicles, and for such like purposes.
We WILLIAM STEWARD and HARRY CURETON trading as Cureton and
Steward both of Staniforth Street Lamp Works Staniforth Street Birmingham in
the County of Warwick, Manufacturers, 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 :-
Our invention relates to a means for securing and locking the lamps upon the
brackets of bicycles, tricycles and the like and it consists in the construction of a
lock plate or lock back arrangement which is connected to the back of the lamp
and is also connected to the socket or slide that fits onto the lamp bracket.
At the lower end of the lock plate or lock back is a catch of a peculiar forma-
tion which may be hinged pivotted or otherwise suitably connected to the lock
plate or back. This catch is bent to form a kind of hook and tongue and having
a slot cut in its flat surface into which the drop down bolt of the lock takes.
Within the lock plate or lock back is an arrangement forming the locking
mechanism consisting of a perpendicular rack having a bolt upon its lower edge
which rises and falls when operated and which is kept in position by side pieces or
grooved strips. Working into this rack is a pinion or spur wheel supported by
bearings and having a square" formed by the extension of the centre pin or axle
of the ratchet whereon fits a key for locking and unlocking the bolt.

The locking arrangement may be in any suitable position upon the lock plate.

parts
Figure 1, is a side elevation of a bicycle lamp with the improved lock plate or
lock back connected thereto shewn locked.
Figure 2, is a side elevation of the lock plate or lock back alone shewn
unlocked.
Figure 3, is a side elevation to a larger scale shewing the pinion or spur wheel
and bolt (locked).
Figure 4, is a side elevation of the plate that encloses the locking mechanism.
Figure 5, is a front elevation with the outer plate removed shewing the rack
bolt and spur wheel also key for actuating same.
Figures 6 and 7, views of rack and bolt and spur wheel, separately.
A, is the lamp connected to which as shewn is the lock plate or lock back B
carrying the socket or slide C, supported by the bracket D on the machine, E is
the hook like catch and tongue hinged pivotted or otherwise attached as at F to
the lock plate B, G is the rack carrying the bolt C, H is the pinion or spur
wheel actuated in its centre by the key I.
Assuming the lamp is in position upon the bracket on the machine the hook
catch E is turned up the tongue thereof passing through the lock plate or back B,
horizontally as at J and underneath the bracket D, Figures 1, 3, and 5, the key is
then turned thus actuating the spur wheel H thereby causing the rack G to
descend and shooting the bolt Ginto the slot cut out for the purpose in the
tongue of the catch E. The shoulder E₁ formed by the angle of the hook like
catch bears against the under side of the bracket as stated and effectually prevents
the lamp from being lifted off or stolen until the catch is unlocked and turned back
see Figure 2, when the lamp may be easily removed.
We wish it to be understood that we do not limit ourselves to the mere precise
details of construction and arrangement as hercin set forth and illustrated as we
may vary the several parts to suit different requirements.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
Firstly. In lamps for bicycles tricycles and other velocipedes and vehicles the
locking arrangement for attaching and locking the same on to the brackets
substantially in manner as set forth.
Secondly. In lamps for bicycles tricycles and other velocipedes the arrangement
of the lock plate or back B containing the rack plate and bolt G, G', the pinion
or spur wheel H also the catch piece or hook and tongue E, all constructed and
arranged substantially as described and operating in the manner and for the purpose
specified.
