Improvements in Small Arms.
I, EDWARD BENNETT of Groveland, in the County of Liveston, State of New
York, United States of America, Carpenter, 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 :-
My invention relates to the locking attachment for the barrel in breech-loading
fire-arms; and the invention consists in the combination and arrangement of parts
hereinafter described and claimed.
In the drawings,
Figure 1 is a longitudinal sectional view of a portion of a gun showing my
invention.
Fig. 2 is an enlarged sectional view of same.
Fig. 3 is a diagram showing a side elevation of the breech and the barrel in
the unlocked and open position.
Fig. 4 is a cross-section of the breech and a rear-end elevation of the barrel.
Figs. 5 and 6 are detail views in perspective of the locking attachments.
Fig. 7 is a detail view of the ejector, and Fig. 8 is a sectional view showing the
ejector in position.
A indicates the breech and B the barrel, the same being jointed in the ordinary
manner, so that the rear of the barrel may be opened upward to insert the
cartridges and discharge the shells. As shown in the drawings, the barrel
contains a rifle and a shotgun bore, one above the other. It may be otherwise
arranged if desired.
C is the locking-lever on the underside of the gun the front end being pivoted
at a to the ordinary slotted lug b, attached to the underside of the barrel. The
barrel is raised by throwing the lever downward and forward and then raising it
vertically, as shown by dotted lines in Fig. 1.
D is a locking-block, consisting of a bar c, seated in a groove in the under side
of the stock and having free movement forward and back to a limited extent, its
front end entering the slot in the lug b and locking the barrel in place. It is
provided on its under side with an angular bearing d, between the sides of which
the locking lever passes. It has two reverse inclined shoulders fand g, the first
extending upward and backward and the other upward and forward, as shown in
Figs. 2 and 5. The head of the locking-lever has two corresponding inclined
shoulders and i, which, when the lever is locked, fit said shoulders of the
bearing, as shown in Fig. 2. The block is pressed backward by a small spring k,
which rests at one end against a shoulder m of the block and at the other against a
similar shoulder n of the stock.
In the locked position the lever C is held up by the back pressure of the locking-
block D, the shoulder i of the lever holding over the corresponding shoulder g of
the block. Sufficient downward pressure on the lever causes the inclined shoulder i
to force the block forward till the lever is released, when the lever is free and can
be used, as before described to raise the barrel. When the block is free of the
handle the spring forces it back, so that the front end of the block frees from the
hotch in the lug b and releases the barrel and allows it to be raised. In the back
movement of the lever to lock the barrel again, the inclined shoulder i of the lever
trikes under and back of the inclined shoulder f of the block and forces it forward

page_text: again, forcing the front end into the slot of lug b. The novelty consists more
especially in the spring-block provided with the reverse inclined shoulders and the
lever provided with corresponding shoulders, whereby the lever is held up in place
and acts automatically in opening and closing the block.
s is the ejector for ejecting the empty shells, the same being located in a
depression or cavity at the rear end of the barrel in the ordinary way. t is an arm
for operating the ejector. It is located in a cavity v made in one of the outer sides
of the barrel, and it has an off-set-pivot w, marked in dotted lines, Figs. 1 and 3.
This pivot being eccentric to the pivot on which the barrel turns in opening and
closing, the tendency is to throw the arm out in the opening movement and draw it
back in the closing movement of the barrel, the same being done automatically. It
therefore pushes the ejector out in opening the barrel and draws it back in closing
it. The other end of the arm is connected with the ejector by a tenon y, which
passes through the ejector.
The rifle-barrel is provided with spiral grooves pp as usual, but in this case they
differ from the ordinary grooves by being made V-shaped in cross-section and
brought to a sharp edge at their inner depth. By this means they are more
effective, as the ball more readily fills them, and there is less wear and tendency to
lead the barrel.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. In a breech loading firearm, the combination with a locking lever provided
with reversely inclined shoulders, of a spring block provided with corresponding
inclined shoulders, the whole arranged to operate in the manner and for the
purpose specified.
2. A rifle barrel having spiral grooves of V shape in cross section, said grooves
terminating in a sharp edge at their inner depth, substantially as set forth.
3. In a gun, a combination barrel, the same comprising a shot bore and a
rifle bore, the said bores being arranged, one above the other, substantially as
set forth.
4. The improvements in small arms substantially as and for the purposes
hereinbefore described, set forth and illustrated in the drawings.
Dated this 20th day of January 1896.
