Improvements in Cases or Canisters for Containing or Carrying
Gunpowder or other Explosive.
We JAMES ROBINSON LINSLEY of Cramlington Northumberland Mining Engineer
and JOHN HENRY PROCTOR of 29 Side Newcastle upon Tyne Ironmonger do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to render cases or canisters for containing or carrying
gunpowder or other explosive self closing and self locking so as to prevent the
gunpowder or other explosive from being extracted when the case or canister may be
left by the authorized attendant and thereby reduce the risk of accident by preventing
these explosives being in the hands of unauthorized persons.
This is accomplished in the following manner. Attached to the lid of the canister
there is a spiral or other form of spring, the opposite end of this spring is attached
to the canister itself by preference to the back thereof on the inside so that when the
lid is opened it cannot remain so when left owing to the tension of the spring bringing
the lid down and so closing the case. As the lid thus closes by its spring there is a
spring lock which is self locking so that as the sprints which are fixed on the lid enter
the lock the bolt of the lock is thrust back by these sprints and when the aperture in
sprints is brought into position opposite the bolt the spring of the lock shoots the bolt
forward into the aperture of the sprints and so the case is not only closed but is also
securely locked and cannot be opened again without the aid of a key.
The spring or springs for lid before mentioned may be if preferred on the outside of
the canister or they may form part of the hinge.

We JAMES ROBINSON LINSLEY of Cramlington Northumberland Mining Engineer
and JOHN HENRY PROOTOR of 29 Side Newcastle upon Tyne Ironmonger 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
The object of this invention is to render cases or canisters for containing or carrying
gunpowder or other explosive self closing and self locking so as to prevent the
gunpowder or other explosive from being extracted when the case or canister may be
left by the authorised attendant and thereby reduce the risk of accidents by preventing
these explosives being in the hands of unauthorised persons.
This is accomplished in the following manner. Attached to the lid of the canister
there is a spiral or other form of spring the opposite end of this spring is attached to
the canister itself, by preference to the back thereof on the inside so that when the lid
is opened it cannot remain so when left, owing to the tension of the spring bringing
the lid down and so closing the case. As the lid thus closes by its spring there is a
spring lock which is self locking so that as the sprints which are fixed on the lid enter
the lock the bolt of the lock is thrust back by these sprints and when the aperture or
notch is brought into position opposite the bolt, the spring of the lock shoots the bolt
forward into the aperture or notch of the sprints and so the case is not only
closed but is also securely locked and cannot be opened again without the aid of a key.
The spring or springs for lid before mentioned may be if preferred on the outside of
the canister or they may form part of the hinge.
Fig. 1 is a sectional elevation of the case, the case is marked a, the lid e the spring
for lid 6 the sprints & the bolts of lock c and the brackets for carrying the whole f
Fig. 2 is a plan of Fig. 1 and Fig. 3 is a side elevation shewing sprints & and bolts
of lock c.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
A spring on hinge or in other suitable position in combination with a spring lock so
as to insure the closing and locking of canisters for gunpowder or other explosive as
hereinbefore described.
