IMPROVEMENTS IN SELF COCKING FIRING APPARATUS FOR ORDNANCE
Year: 1884

page_text: 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 SELF COCKING FIRING APPARATUS FOR ORDNANCE" to be
as follows:-
My Invention relates to the firing of percussion primers or cartridges for breech-
loading ordnance by means of a self-cocking rebounding spiral spring lock or
apparatus of a cylindrical form and of small diameter which apparatus is to be
placed in a chamber in the axis of the breechscrew or sliding block of the gun and
is secured therein by means of a sliding shutter; or the said apparatus may be
screwed into its place by hand.
This apparatus consists essentially of a steel cylindrical case the front part of
which is formed to hold a central fire percussion primer or cartridge with a rim;
and behind this a striker is held in equilibrium by means of one or two spiral
springs which act upon the sides of a collar on the said striker in such manner
that when at rest the striker shall not be in contact with the primer.
The rear end of the striker passes through the end of another small cylinder,
which is screwed into the first cylinder, which contains a piston actuated by another
spiral spring. In this piston a sinall lever or trigger is hinged, which is adapted
to hook into a notch formed in the end of the striker. A pin or stop is fixed in
the cylinder over the trigger so that on the piston being drawn back the rear end
of the trigger is pressed down whereby the other end is released from the striker
which striker is immediately projected forwards against the primer and then
retracted by means of the front spiral spring. The trigger is immediately recon-
nected to the striker by means of the spiral spring in the rear forcing the said
trigger-piston forward. A small flat spring assists to keep the trigger in a proper
position for connecting with the striker.
In the Drawing Figure 1 is a longitudinal section; Figure 2, an elevation of
the front end; and Figure 3, an elevation of the rear end of this firing apparatus.
Dated this Twentieth day of November 1884.

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 SELF-COCKING FIRING APPARATUS FOR 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 firing percussion primers or cartridges for breech loading
ordnance, by means of a self cocking rebounding spiral spring lock or apparatus of
a cylindrical form, and of small diameter, which apparatus is to be placed in a
chamber in the axis of the breech screw or sliding block of the gun, and is secured
therein by means of a sliding shutter; or the said apparatus may be screwed into
its place by hand.
This apparatus consists essentially of a steel cylindrical case, the front part of
which, is formed to hold a central fire percussion primer or cartridge with a rim,
and behind this a striker is held in equilibrium by means of one or two spiral
springs, which act upon the sides of a collar on the said striker in such manner,
that when at rest the striker shall not be in contact with the primer.
The rear end of the striker passes through the end of another small cylinder,
which is screwed into the first cylinder, which contains a piston actuated by another
spiral spring. In this piston a small lever or trigger is hinged, which is adapted
to hook into a notch formed in the end of the striker. A pin or stop is fixed in
the cylinder over the trigger, so that on the piston being drawn back the rear end
of the trigger is pressed down, whereby the other end is released from the striker,
which striker is immediately projected forwards against the primer and then
retracted by means of the front spiral spring.
The trigger is immediately reconnected to the striker by means of the spiral
spring in the rear, forcing the said trigger-piston forward.
A small flat spring assists to keep the trigger in a proper position for connecting
with the 'striker.
In the accompanying drawing figure 1, is a longitudinal section; figure 2 an
elevation of the front end and figure 3 an elevation of the rear end of a self
cocking firing apparatus for ordnance constructed according to my invention.―
Similar letters in all the figures represent similar parts.
A represents the front end of the metal case into which the rear part A¹, is
screwed; B, is the striker; C is the trigger-piston, and D is the primer holder; v is
the front spiral spring which causes the striker to rebound after firing; vl, is, the
spiral spring which projects the striker forward against the percussion primer when
the trigger is disengaged from the notch in the end of the said striker; v², is the
spiral spring which forces forward the trigger piston so as to reconnect the said
trigger to the striker immediately after firing; x, is. the pin or stop fixed in the
case A¹, and by means of which the rear end of the trigger is pressed down on
the piston being drawn sufficiently far back whereby the front end of the said
trigger is released from the notch in the striker; z, is the said trigger and y, is
the flat spring which assists to keep the trigger in proper position to allow of its
being connected to the striker.

page_text: 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 self cocking rebounding percussion lock for firing percussion primers in
ordnance, consisting of a striker held in equilibrium by spiral springs, a trigger
piston adapted for the said trigger to engage into a notch in the rear end of
the said striker, and of another spiral spring for actuating the said trigger piston
so as to cause the said trigger to engage with the said striker, in combination with
a fixed pin or stop adapted to act on the said trigger, so as to release the said
striker at the proper instant to fire the percussion primers substantially as herein-
before described and represented in the accompanying drawing.
