Year: 1885

page_text: I ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex,
Engineer do hereby declare the nature of the said invention for "IMPROVEMENTS
IN REPEATING MECHANISM FOR BREECH-LOADING FIREARMS a communication
from Count Rudolf de Montgelas of Egglkofen, Germany to be as follows:―
"
This mechanism can be employed in all or most known breech loading systems
provided with cylindrical breech bolt.
The apparatus is shown in the figures 1, 2, and 3 of the accompanying drawing
the figures 4 and 5 represent the apparatus in combination with a breech-loading
rifle, the figures 6, 7 and 7ª show the reservoir for cartridges used in the
repeating mechanism.
The figures 8 and 9 show the contrivance for fixing the mechanism to the rifle
and the figures 10 and 11 the cam fixed to the breech bolt.
In the cylinder a (see figures 1 and 2) is a piston 6 which is excavated and forms
so a sort of spoon as shown in figure 3.
On the head of the piston b is a circular groove c The cylinder a has a slit d
running in the direction of the longitudinal axis of the cylinder but bending
laterally off in the fore part in the direction of a screw-line. A pin e secured to
the piston b catches into this slit. In drawing the piston b out of the cylinder a
the pin e will slide in the slit and finally cause the piston to turn.
Upon the cylinder a is secured the reservoir for cartridges f (see figures 6 and 7)
in such a way that a turning hoop g fixed to the cylinder a is flapped up and
encloses so the reservoir (figures 1 and 2).
In order to prevent the cartridges from falling out of the reservoir the opening
is covered by pasting paper over, which is taken off before putting the reservoir
upon the repeating mechanism. A partition x which may be movable or fixed
(figures 7 and 7a) divides the reservoir into two parts.
After the filled reservoir having been put upon the cylinder a (figure 1) a
cartridge will fall into the cavity of the piston b and is taken with, when 6 is
drawn out.

page_text: The whole apparatus is now fixed to the stock at the side of the rifle by means
of the contrivance shown in the figures S and 9. The part is secured to the
stock by means of screws; in the slit of this part is placed the flap 1 (figures 1
and 2) fixed to the cylinder a and maintained in its position by the spring m.
The cam shown in the figures 10 and 11 is fixed to the cylindrical breech bolt
and catches from below with its semi-circular hoop into the circular groove c of
the piston b (see figures 4 and 5).
The repeating mechanism works in the following manner.
In opening the rifle the piston b is drawn out by the cam p secured to the breech
bolt when the latter is withdrawn.
In the cavity (spoon) of the piston b is lodged a cartridge, which is thrown on
the end of the movement of the piston in consequence of its revolution into the
open chamber opposite to the spoon.
When the rifle now will be shut the piston goes also back and receives a new
cartridge in its cavity (spoon).
After the rifle having been discharged the same play will recommence on
opening the rifle.
The shell or case of the discharged cartridge will be removed by a suitable
contrivance shortly before the cartridge will slide out of the spoon into the
chamber. The reservoir when it has become void may be quickly replaced by a
filled one after the hoop having been let down.
If the rifle has to work as an ordinary breech-loader the repeating mechanism
can easily and quickly be removed, or the whole mechanism is raised so that the
spring m catches into the lower rest z (see figure 1).
In this position the semi-circular hoop p (figures 4. 5. 10 and 11) does no more
catch into the groove c and the shutting-piston moves to and fro without the
spoon b being taken with it.
The partition in the reservoir for cartridges has for its purpose to prevent a
stoppage in the sliding out of the cartridges. First one half of the reservoir will
become void and then the other half.
In lieu of the above described reservoir for cartridges f an otherwise shaped
reservoir with or without interior partition may also be employed.
The pin e is disposed in an elastic manner for the purpose to allow the piston b
to be removed entirely out of the cylinder a for cleaning etc. In order to obtain
this the pin is forced backward up to the surface of the piston b which then can
be drawn out.
The springs (figure 1) on the outside of the cylinder a presses by means of a
small projection passing through an opening in the wall of the cylinder a upon the
piston and prevents so the latter from sliding out of the cylinder a, when the
repeating mechanism has been raised that is to say has been put out of operation.
The handle (knob) y has a backward bent form, as shown in the figures 4 and 5
in order to allow the operation when pointing. the rifle.

I, ALFRED JULIUS BOULT, 323 High Holborn, Middlesex Mechanical Engineer
do hereby declare the nature of this invention (a communication from abroad by
Count Rudolf de Montgelas, of Egglkofen in Bavaria) and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This new apparatus can be employed in all known breech loading systems,
provided with cylindrical breech bolt.
The apparatus is shown in the figures 1, 2, and 3 of the accompanying
drawing; the figures 4 and 5 represent the apparatus in combination with a
breech-loading rifle; the figures 6 and 7 show the contrivance for fixing the
mechanism to the rifle and the figures 8 and 9 the cam fixed to the breech bolt.
In the cylinder a (see Figures 1 and 2) is a piston b, the rear half of which is
hollowed out, and forms so a sort of spoon as shown in Figure 3. On the head of
the piston b is a circular groove c. The cylinder a has a slit d running in the
direction of the longitudinal axis of the cylinder but bending laterally off in the
forepart in the direction of a screw line. A pin e secured to the piston b catches
into this slit. In drawing the piston bout of the cylinder a, the pin e will slide
in the slit and finally cause the piston to turn.
Upon the cylinder a is secured the reservoir for cartridges f, which is provided
on its upper part with a cover in order to fill the cartridges.
A partition which may be moveable (Figure 2) or fixed (Figure 2) divides
the reservoir into two parts.
The cartridges fall into the cavity (spoon) of the piston b and travel with the
spoon, when the latter is drawn out.
The whole apparatus is now fixed to the stock at the side of the rifle by means
of the contrivance shown in the Figures 6 and 7. The part is secured to the
stock by means of screws, in the slit of this part is placed the flap (Figures 1
and 2) fixed to the cylinder a, and maintained in its position by the spring m.
The camp shown in the figures 8 and 9 is fixed to the cylindrical breech bolt and
catches from below with its semi-circular hoop into the circular groove c of the
piston 6 (see Figures 4 and 5).
b
The repeating mechanism works in the following manner.
In opening the rifle the piston b is drawn out by the cam p secured to the
closure when the latter is withdrawn. In the cavity (spoon) of the piston bis
lodged a cartridge which is thrown on the end of the movement of the piston in
consequence of its revolution into the open chamber opposite to the spoon.
b
When the rifle is shut, the piston 6 goes back, and receives a fresh cartridge in
its cavity (spoon). After the rifle has been discharged the same action will
recommence on opening the rifle.
The shell of the discharged cartridge is removed by a suitable contrivance
shortly before the fresh cartridge slides out of the spoon into the chamber,

page_text: The reservoir when it has become empty may be quickly filled again after
opening the cover g.
If the rifle has to be used as an ordinary breech loader the repeating mechanism
can easily and quickly be removed, or the whole mechanism is raised, so that the
spring m catches into the lower rest 9 (see Figure 1). In this position the semi-
circular hoop p (Figures 4, 5, 6, and 7) no longer catches into the groove c and
the closing piston moves to and fro without the spoon b being actuated,
The partition in the reservoir for cartridges has for its purpose to prevent a
stoppage in the sliding out of the cartridges. First one half of the reservoir will
become empty and then the other half.
In lieu of the above described reservoir for cartridges f a differently shaped
reservoir with or without interior partition may be employed.
The pin e is disposed in an elastic manner, in order to allow the piston 6 to be
removed entirely out of the cylinder a for cleaning etc. In order to obtain this,
the pin is forced backward up to the surface of the piston b which then can be
.drawn out.
The springs (Figure 1) on the outside of the cylinder a, presses, by means of a
small projection passing through an opening in the wall of the cylinder α, upon
the piston b and prevents so the latter from sliding out of the cylinder a when the
repeating mechanism has been raised, that is to say, has been put out of operation.
The handle (knob) y has a backward bent form as shown in the figures 4 and 5,
in order to facilitate its operation when the rifle is aimed at an object.
. Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is
A repeating mechanism for breech loaders consisting of the combination of a
cylinder a with a spoon b and a reservoir for cartridges f in connection with a
camp secured to the cylindrical closure and catching into the groove c of the
spoon b, so that in opening the rifle, the spoon b containing a cartridge is drawn
out of the cylinder a, and delivers in consequence of the revolution the cartridge
into the chamber of the rifle.
