I, CHARLES PIERRE NEWTON WEATHERBY, of 28 East 74th Street, in the City
and State of New York, United States of America, Gentleman, 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 said improvements relate first to the magazines, two of which are employed,
Each
one being located in the butt stock and the other under the harrel.
magazine is provided with a cut-off, so that cartridges may be taken from the
magazines alternately, or all may be taken from one before any are taken from
the other magazine, and when both magazines are closed the gun may be used as
an ordinary breech loader; Second, to the magazine tubes which are formed with
wave corrugations on the bottom or side, so that the point of one bullet cannot
strike against the primer of the next preceding cartridge; Third, to a double irregular
immovable incline, by which the cartridges from the front and rear magazines are
guided in their transfer to the barrel; Fourth, to the loading and extracting device,
which consists of a bolt formed with a lip and a solid extracting hook, by which
means the cartridges from either magazine are held and forced into the barrel and
the shells withdrawn; Fifth, to the device for locking the bolt, and, Sixth, to the
construction of the trigger.
In the accompanying drawings forming a part of this specification.

:
The two magazines, M, N, are located in front and rear of the irregular incline X.
These magazines are provided with cut-off slides O, P, operated by push buttons o, p':
These buttons as shown are operated separately by hand. The cartridges are forced
forward by spiral springs S when the slides O, P, are opened. The magazine tubes
are formed with wave corrugations m and n as shown, for the purpose of preventing
the bullet point of one cartridge striking against the primer in the next preceding
cartridge. By this construction the form of the cartridge is preserved and the danger
of accidental discharge is avoided.
The double incline X is formed of an irregular shape as shown, for the purpose of
guiding the cartridge as it is forced from the magazine. It will be observed that the
two sides are of different shape. This variation is necessary in order to bring the rim
of the cartridge into proper contact with the extracting hook.
The bolt is constructed in two parts C, D. The front part C is provided with a
solid bevelled extracting hook I, which in connection with lip J formed on or secured.
to the bolt, seizes hold of the cartridge that has been forced up the irregular incline
by the magazine spring. The extractor is so bevelled as to conform to the bevelled
recess K formed in the chamber of the barrel, so as to solidly press the extracting
hook on the rim of the cartridge shell.
The locking piece T fits into a recess t¹ on the side of the bolt, to prevent the same
from turning or dropping out when the gun is used for drilling purposes.
The locking piece T, prevents accidental discharge, by permanently locking the
bolt from turning, or dropping back; to be discharged the bolt must be turned
down.
The independent pivotted trigger R is formed so as to press upon the sear Q, to
release it from the cocking notches g, g, on bolt fin F, when the bolt is turned down
for firing, also to release catch U, on end of sear, from rim of cartridge.
The magazines are filled from the same aperture L, and the cartridges are retained
in the rear magazine by a catch U on end of sear Q, and in the front magazine by
lip J on part of the bolt. The lip Jacts as a rest to hold the cartridges from
dropping away from the extracting book I, when the bolt is being drawn back, and
the magazine N'in use. When loading magazine N, the rim of the cartridges rest
on it to prevent their slipping out, as seen in Fig. 5, till the bolt is pushed forward,
when it presses the last cartridge low enough for the bolt to slip past, and allow
magazine slide P, to be closed, thus entirely cutting' off magazine N. If necessary
to make it longer to lift the cartridge, it will then be made with an opening in it to
allow the cartridges from rear magazine to pass through it. When filled the two
magazines are closed by means of slides, O, P, and the gun may then be used as an
ordinary breech loader until it is desired to use it as a repeater.
Then the slides may
be opened to fire alternately or to fire all from one magazine.
The front or rear magazine being opened, a cartridge is forced up the front or rear
part of the irregular incline and under the extracting hook, and drawn or pushed into
position by the bolt, to enter the chamber, and being forced home, the bolt is turned
down and the sear released-and the cartridge discharged.
The sear is formed of one piece having a solid ring through which the cartridges
pass from rear magazine, with a catch on end for holding cartridges in rear magazine,
and with projections on top of solid ring to enter cocking notches 9, 9, on bolt fin F,
to prevent the discharge of gun till pressed clear of cocking notches by trigger R,
when bolt is turned down.

page_text: The firing pin is released only when bolt lever E is turned down.
The means of preventing the release of the firing pin when the bolt is not turned
down, is by the resting of the rear part D of the bolt, against the end of the inclined
cocking slot, on the front part C of the bolt, in which there is a slight notch, hence
the sear can be dropped clear of the notches g, g, in bolt fin F, while the bolt remains
fixed. When released by turning the bolt down, and away from the end of the
inclined cocking slot the firing pin is released by actuating the trigger. The cocking
slot is also the cocking device, which is operated by turning the bolt upward, separating
the front from the rear, and causing the opening shown at G, Fig. 4.
When the bolt lever is turned up the gun is cocked by the same movement, and
thus the point of the firing pin is removed from the primer of the exploded cartridge.
The bolt being now forced back extracts the shell, said extraction being made certain
by the pressure of the bevelled extracting hook into the bevelled recess in the
chamber.
The cartridges are ejected by being forced into the notch W by the extracting
hook I, in the backward movement of the bolt.
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 :-
First. In a fire-arm a front and rear magazine M, N, for the purposes herein set
forth.
Second. In a fire-arm a double irregular incline X for the purpose herein set
forth.
Third. In a fire-arm a loading and extracting device consisting of bolt C and
extractor I, constructed and arranged substantially as set forth.
Fourth. In a fire-arm extracting hook I bevelled on its upper side, in combination
with a corresponding bevelled recess K in the chamber, for the purpose herein set
forth.
Fifth. In a fire-arm a magazine the bottom or side of which has wave corrugations
formed thereon for the purpose herein set forth.
Sixth. In a fire-arm having a magazine in the butt stock, a trigger R constructed
substantially as and for the purpose herein set forth.
Seventh. In a fire-arm a slide T operated by push button t, in combination with
a recess formed on the bolt, substantially as and for the purpose herein set forth.
Dated this 5th day of November 1887.
