IMPROVEMENTS IN ORDNANCE
Year: 1884

page_text: I, GEORGE QUICK, of Chipping Campden in the County of Gloucester, Chief
Engineer, Royal Navy, do bereby declare the nature of my invention for
"IMPROVEMENTS IN ORDNANCE" to be as follows:-
My Invention relates to an additional fitting to the mechanism described in my
Provisional Specification "Improvements in Ordnance" No: 1115 of A.D. 1884, by
which additional fitting, percussion primers may be used for igniting the powder
charge, in lieu of the Friction or Electric primers.
I effect this by fitting on the rear face of a vent-shutter somewhat similar to
that described in my said Provisional Specification No: 1115 of A.D. 1884. a self
cocking rebounding gunlock, the said gunlock mechanism being enclosed in a strong
metal case, and having a trigger with a straight pull which trigger is adapted to be
pulled by means of a lanyard.
The gunlock is of such construction that the act of pulling the trigger cocks and
fires the lock. The vent-shutter and primer-extractor are actuated as described in
my Provisional Specification No 1115 of A.D. 1884.

page_text: COMPLETE SPECIFICATION.
I, GEORGE QUICK, of Chipping Campden, in the County of Gloucester, Chief
Engineer, Royal Navy; do hereby declare the nature of my invention for
"IMPROVEMENTS IN ORDNANCE" and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My Invention relates to an additional fitting to the mechanism described in my
Patent Specification "Improvements in Ordnance" No: 1115 of A.D. 1884, by
which additional fitting percussion primers may be used for igniting the powder
charge in lieu of friction or electric primers.
I effect this by fitting on the rear face of a vent shutter somewhat similar to
that described in my said Patent Specification No. 1115 of A.D. 1884, a self
cocking rebounding percussion lock, the said percussion lock mechanism being
enclosed in a strong metal case, and having a trigger with a straight pull, which
trigger is adapted to be pulled by means of a lanyard.
This percussion lock is of such construction that the act of pulling the trigger
cocks and fires the percussion lock.
The ventshutter and primer extractor may be actuated as described in my Patent
Specification No: 1115 of A.D. 1884.
In the Drawing Fig: 1 is an elevation of the breech of the gun. A, is the body
of the gun; B, is the sliding carriage; C, is the breechscrew; D, is the ventshutter
and case containing the self cocking percussion lock mechanism; E, is the loading-
tray forming part of the sliding-carriage B; G, is the breechscrew-lever on which
the vent-shutter slides, and a is the trigger of the said percussion lock.
Fig 2, is a section of the case containing the said percussion lock mechanism;
D, is the case, the base plate of which forms the vent shutter, and secures the
primer in its place as described in Patent Specification No: 1115 of A.D. 1884.
p, is the pin by which the said lock is actuated by the excentric guide n in Fig: 1.
a is the trigger having a straight pull, which actuates the lever b which has the
hook c jointed to its other extremity, which hook in its turn actuates the hammer d.
e, designates the spring for forcing the lever b down so as to put the hook c into
connection with the hammer d; f is the principal spring for actuating the
hammer d; g is a slight spring for preventing the hook c from being accidentally
thrown out of gear with the hammer d; and is the spring to cause the
rebounding action of the haminer d.
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
1, the fitting of a self cocking percussion lock suitable for firing percussion primers
unto a sliding ventshutter.
2, the construction of such self cocking percussion lock with a trigger having a
straight pull.
3, the combination of a ventshutter with a percussion lock, the said lock having
a rebounding and self cocking action. .
Dated this Sixth day of May A.D. 1885.
