PROVISIONAL SPECIFICATION.
Improved Apparatus for Adapting Ordnance for Miniature
Ammunition Practice.
We, CHARLES CUTHBERTSON, of No. 107, Sebert Road, Forest Gate, in the
County of Essex, Engineer, and WILLIAM HENRY STENTIFORD, of No. 105,
Shakespear Road, Herne Hill in the County of Surrey, Engineer, do hereby
declare the nature of this invention to be as follows:-
It is often found desirable for drill purposes to fix on or in a cannon a rifle barrel
by which practice is made with miniature ammunition:
This invention relates to an appliance for firing a rifle under these conditions in
the same way as the cannon itself would be fired by a lanyard which by the act of
firing becomes detached.
For this purpose, there is pivotted on the trigger guard of the rifle, a lever the
one end of which bears against the trigger at the point where the finger is usually
applied for firing; the other end, which projects a little beyond the trigger guard,
has through it a hole counter sunk on both sides. To a suitable lanyard is attached
a Ụ shaped spring each limb of which presents inwardly a rounded stud. This
spring can be sprung on the external end of the lever above mentioned, its rounded
studs just entering the countersunk hole and taking sufficient hold to move the
trigger when the lanyard is pulled, but to give way and become detached by the
jerk of the pull.
Dated this 11th day of February 1892.

COMPLETE SPECIFICATION.
Improved Apparatus for Adapting Ordnance for Miniature
Ammunition Practice.
We, CHARLES CUTHBERTSON, of No. 107 Sebert Road, Forest Gate, in the
County of Essex, Engineer, and WILLIAM HENRY STENTIFORD, of No. 105,
Shakespear Road, Herne Hill, in the County of Surrey, 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 :-
It is often found desirable for drill purposes to fix on or in a cannon a rifle barrel
by which practice is made with miniature ammunition.
This invention relates to an appliance for firing a rifle under these conditions in
the same way as the cannon itself would be fired by a lanyard which by the act of
firing becomes detached. The appliance for this purpose is shewn in side view
Fig. 1 and in end view Fig. 2 of the accompanying drawings.
There is pivotted on the trigger guard A of the rifle, a lever B the one end of
which bears against the trigger C at the point where the finger is usually applied
for firing; the other end which projects a little beyond the trigger guard A, has
through it a hole. To a suitable lanyard is attached a U shaped spring E each
limb of which presents inwardly a rounded stud. This spring can be pushed on
the external end of the lever B which is made wedge shaped to allow this, and its
rounded studs just entering the hole of B take sufficient hold to move the trigger C
when the lanyard is pulled, but give way and become detached by the jerk of the
pull. Thus, as in firing a large gun, the lanyard becomes detached, and has to be

page_text: again attached by springing the loop E on the lever B, before the arm can be fired
again.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In combination with the trigger and trigger guard of a rifle, a lever spring loop
and lanyard, substantially as and for the purpose set forth.
