Warwick REUBEN BULLOCK Gun Maker No. 11 St. Marys Row Birmingham in the
County of Warwick do hereby declare the nature of this invention to be as follows:-
-
The object of our invention is to effect further improvements in our invention
Patent Spec.-dated May 23rd 1887 No. 7470. Our invention consists of a new
method of intercepting the unfired cartridge untill the Gun is fired from drop down
Guns. Our method is to cut a slot down centre of face of breech block and two cross
slots on top of breech block; deep enough to intersect the striker hole, and long
enough to intersect the centre slot. In these cross slots we fit plates which oscillate
on a pin passing through block and plate near the centre. To actuate the oscillating
plates we fit a stud on the head of the extractor, which projects into and moves
down the centre slot when closing the Gun and engages with and presses down the
end of oscillating plates and so raises the other end into position to intercept the
cartridge; and is retained in that position by resting on the striker. When the gun
is fired the plate is pressed into a notch (made in the striker) by a small spring.
The above arrangements of our intercepters are used in combination with our
ejector mechanism as represented and described in patent spec.-dated May 23rd 1887
No. 7470.

ISAAC BULLOOK Gun Maker 11 St. Mary's Row Birmingham Warwickshire REUBEN
BULLOCK Gun Maker 11 St. Mary's Row Birmingham Warwickshire 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 consists of a new method of intercepting the unfired cartridge
(until the Gun is fired) from drop down Guns. Our method is to cut a slot down
the centre of face of breech block; and two cross slots in the top of breech block;
deep enough to intersect the striker holes and long enough to intersect the centre
slot. In these cross slots we fit plates which oscillate on a pin i passing through
block and plate near the centre slot. To actuate the oscillating plates, we fit a stud
on the head of the extractor which projects into and moves down the centre slot
when closing the Gun, and engages with and presses down the end of oscillating
plates, and so raises the other end into position to intercept the cartridge; and is
retained in that position by resting on the striker. When the gun is fired the plate
is pressed into a notch (made in the striker) by a small spring.
In proceeding to fully describe our invention which is applicable to all kinds of
drop actions, we shall therefore in the accompanying drawings use only the outline
of a drop Gun without reference to any particular system of bolting. And in order
that our invention may be particularly described and ascertained; reference is
hereby made to the accompanying drawings.
Fig. 1 is a side view of barrels and action showing the stud A on the head of the
extractor in position to move down the centre slot B by the closeing of the Gun. In
passing down the centre slot B, the stud A presses upon the projecting arms of the
oscillating plates OC and so raises the top of the oscillating plates above the action,
and they are retained in that position by resting on the full part of the striker D D.
Fig. 2 shews the face of the action, the centre slot B and the intercepters O.C
raised above the action. Fig. 3 shows the face of the action, the contre slot B and
the intercepters down, in position to allow the cartridge cases to be ejected. The
oscillating plates CC are held in position (as shewn in Fig. 3) by means of a
Ushaped spring E which is fitted down the sides of the centre slot B, the ends of
the spring E pressing the arms of the intercepters CO always to the centro of the
slot B.
Fig. 4 shows the top of breech action also the cross slots F F and the strikers D D
When the hammer falls on the striker D, the notch in the striker is moved forward
under the intercepters; which being forced by spring E falls into the notch in the
striker D.
When the intercepters are raised by the closeing of the Gun (as before discribed)
a small coiled spring H in front of the striker D forces the striker back for the
intercepters to rest upon.

page_text: Fig. 5 shews all the parts for ejecting as represented and discribed in Specifications
of letters patent No. 7470 dated May 23rd 1887.
Fig. 6 shews all the parts for intercepting; and shews the arms G G as a modifica-
tion of the plates CC.
Haveing now particularly discribed and ascertained the nature of our invention
and in what manner the same is performed, we declare that
1st. We claim to cut in the cross slots F F and place in the slots so cut; the
oscillating plates CC or arms G G as shown in Fig. 6.
2nd. We claim the stud A and its combination with the intercepters C C and G G
for the purpose of raiseing the said intercepters into position to intercept the unfired
cartridge.
3rd. We claim the combination of the strikers D D with the intercepters for
retaining the intercepters in the proper position.
