page_text: I EMMANUEL AMODEO SALVATOR of Washington, District of Columbia, United States
of America, 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 object of the invention is to produce a fire arm adapted for any very rapid firing
and for being fed directly from the magazine supported on a belt worn by the person
using the weapon and it consists in the constructions hereinafter described and
particularly indicated in the claims.
In the accompanying drawings which form a part of this specification, figure 1
represents a sectional view shewing the several parts of the gun in position for firing;
figure 2 is an enlarged section shewing the position of the parts with a cartridge in the
cylinder ready to be inserted in the barrel of the gun; figure 3 is a detail plan view
with parts broken away; figure 4 is a cross section of the cartridge cylinder on the
line,, figure 1; figure 5 is a perspective view of the same shewing the position of
the cartridge carrying ribbon; figures and 7 are detailed views of the portable
magazine; figure 8 is a detail view of the operating lever; figures 9 and 9", are detail

mechanism for revolving the cartridge cylinder; figure 11 is a view of the knife for
severing the ribbon; figure 12 is a side view showing the knife in position in the
cartridge cylinder figure 13 is a side view of the cartridge; figure 14 is a perspective
view of the ribbon holder.
Magazine guns as heretofore constructed for use as fire arins to be held to the
shoulder of the person using them have had their magazines formed in the stock or
some other part of the gun which has made them very unwieldy on account of the
additional weight added to the arm by the loaded cartridges and has had the effect
of taxing the strength of the user to hold the fire arm in a position for execution.
By my invention the magazine is supported by belts about the body and crossing the
shoulder of the person and the fire arm relieved of all weight of the ammunition save that
of the one cartridge in the gun and the few suspended upon the ribbon between the
gun and the magazine.
Another impediment to firing a great number of cartridges in rapid succession has

page_text: been the heating of the barrel to such an extent as to require the firing to be stopped
and time allowed for the parts to cool. To overcome this objection I provide a chamber
around the barrel of the gun which is in communication with a reservoir in the stock
of the gun containing a cooling liquid.
In most or nearly all of the fire arms now in use the sight of the gunner is obstructed
by hammers projecting above the upper surface of the gun; to avoid this I locate the
hammers within the breech block and present a smooth and unobstructed surface to
the eye of the gunner.
In the drawings A represents a cartridge carrying cylinder provided with five
chambers a, adapted to receive and hold a cartridge while it is being pushed into the
barrel of the gun by the moveable breech block B. The cartridge cylinder revolves
upon an axle C which is eccentric to the barrel of the gun and the inner end of the
cylinder is provided with gearing b, which engages with a pinión d; the number of
teeth of the said gearing being in the proportion of three on the pinion to five on the
cylinder.
The pinion d, is attached to a shaft e, which bas its bearings in supports f, g, and is
provided with a worm gear k, and a sleeve i, which has a corresponding nut j, formed
in one end and a spider k, figure 10, in the opposite end through which the shaft e,
passes. Upon the sleeve i, is a sliding collar, provided with a projecting pin m, and
a conical bearing n, (figure 10) which corresponds with the seat o, on the sleeve i, and
is operated by the lever D (which is indirectly attached to the breech block B) by
means of a curved slot p, with which the pin m, engages and by which the cartridge
cylinder is revolved upon the forward stroke of the said lever. To prevent the
possibility of the cylinder A revolving in the opposite direction when the lever D is
returned to its rear position as shewn in figure 1, a ratchet 4, and a pawl r, are
provided, the pawl being held in contact with the ratchet by a springs, (figure 10).
The lever D is bent laterally as shewn in figure 8 to prevent it interfering with the
trigger g and the conduit leading from the reservoir and is pivotted at ", and is provided
with a guard t, in the rear thereof and has a slot e, formed in the arms w, ic, which
engage with a pin y, projecting on both sides of the sliding block z which has a dovetail
projection a¹ formed on the end thereof which engages with a corresponding slot on the
seat in the end of the breech block B.
To prevent the breech block B from being pushed back by the explosion of the
cartridge and the lever D from being thrown forward prematurely, the pivot u is
arranged on a higher horizontal plane than the pin y, and the slots in the arms w, w,
when the parts are in the position shewn in figure 1 and the arm c¹ of the sliding
block is held in position by a spring d¹ bearing upon the outer end thereof.
A spring e¹ is coiled around one end of the breech block and when compressed is
contained in a chamber f¹ formed in the metal which constitutes the rear wall of the
feed wheel chamber and assists in throwing the lever D forward and extracting
the discharged cartridge from the barrel of the gun, by the spring pressing against
the inner face of the sliding block :.
When the lever D is returned to its normal position as shewn in figure 1, the
arms w, we are brought down into the position shewn in the said figure. During this
movement of the lever I the pin y in the arm c¹ of the sliding block moves in the
slots of the arms w, w, moves the said block down in the seat b¹ of the breech-block,
pushes the breech-block B in towards the barrel of the gun, carrying a cartridge with
it, and at the same compresses the spring e¹ into the chamber when the gun is again
ready for firing.
=
The breech-block is made in two parts 1, 2, connected by an ordinary screw-thread
and the part 2 is provided with a chamber 3, within which there is a spring-actuated
hammer 4, and a firing pin 5, provided with a spring 6, which serves as a cushion to
the blow of the hammer and also returns the pin to its normal position after the
cartridge has been exploded. An arm 7, attached to the hammer 4, engages with a
pivotted latch 8, on the front end of the trigger g, and holds the hammer in position
with the spring 10, contracted ready for use. A cam 11, bearing upon the spring 12,
securely locks the trigger g, and prevents any accidental discharge of the cartridge.

page_text: The arm 7, and the latch 8, are held in a locked position at all times when the cartridge
is in the barrel of the gun by the spring 12, bearing upon the trigger g, the projecting
end of said trigger extends into the finger slot of the lever D for convenience of
operating it.
E represents a knife attached to the sliding breech block B by a bolt g¹, and is
pushed into the slots ', in the walls of the chambers, formed in the cartridge
cylinder A (as clearly shown in figure 4) and cuts off the end of the ribbon from
which the cartridge has been removed by the breech block and forced into the barrel
of the gun. The construction of the knife is distinctly shewn in figure 11 and by
reference to figures 4 and 5 it will readily be seen that the slots ', are cut at an angle
to the periphery of the cartridge cylinder to accomodate the reciprocating motion of
the knife and the position which it occupies in relation to the axis of the cylinder.
Secured to the front end of the breech block is an extractor 13, which engages
with the flange of the cartridge and is held in contact therewith by a leaf spring 14,
and is disengaged therefrom upon the back stroke of the breech block by striking the
wall of the cartridge chamber or stock of the gun at 15.
The gun is made in three parts, namely, the barrel F which may be smooth or
rifled, the casing G and the stock H, the several parts being secured together by screw
threads and a plate K¹ hinged to the casing G at 1, and connected to the stock by a
screw m; the casing may extend along the under side of the barrel to the end
thereof.
Upon the inner end of the lower side of the casing G is formed a screw threaded
extension n', which engages with a corresponding screw threaded socket in the
stock H and the barrel F is supported by a block p, which forms the outer end walls
of a cooling chamber I which communicates with a reservoir J in the stock H containing
a suitable cooling liquid by means of a passage ', in the extension n', a conduit,
and a pumps, provided with the usual supply or suction pipe and check valves. The
pumps, is operated by a jointed lever t¹, which is supported in guide ways formed on
the reservoir and projects through the slot ', in the upper edge of the stock H and
the cooling chamber I is provided with a relief valve v¹.
By filling the chamber I with liquid from the reservoir J the inner end of the barrel
is kept cool the parts are prevented from becoming overheated and as a consequence a
very large number of rounds of cartridges may be fired in rapid succession without
danger of premature discharge of the ammunition produced by the overheating of the
metal as frequently occurs in ordinary magazine guns or when they become too hot
for use with safety they must be laid aside to cool.
After the chamber I has been filled the handle or lever ', is folded down into the
slot as shewn in dotted lines in figure 1.
K, (figures 6 and 7) represents the cartridge magazine which consists of a box
having a hinged cover in which the cartridges secured to a ribbon and wound in
concentric layers about a thimble (not shewn) are placed around a central shaft ",
and withdrawn through the opening ¹, and taken to the gun and a cartridge placed
in one of the chambers a, of the revolving cylinder A after which they are fed to the
cylinder automatically by the manipulation of the lever D as will hereinafter more
fully be described.
The magazine is provided with a stud y', projecting from one side and having
grooves, formed in its sides to engage with the flanges a', on the support
attached to the horizontal belt el, at , and to the vertical belt el, at ", and slides
freely therein. It is also provided with a foot piece 111, adapted to rest upon the left
leg of the gunner when in a kneeling position to support the weight of the magazine
and allow it to slide freely in the guide ways formed in the supports 6", attached to
the belts. To insert the cartridges the cover 9", of the magazine. swung open on
its binge", and the coil of ribbon with the cartridges attached is placed in the box
around the central shaft with one end projecting as is shewn in figure 6; the box is
then closed and the cover secured by a hasp when it is ready for use.
:
To secure the cartridges L, to the ribbon M, they are provided with a spring
prong, formed integral therewith and connected near the front end of the cartridge

page_text: as shewn in figure 13. The prong 1, is inserted through the ribbon from the under
side at a right angle to the length thereof and the cartridges are placed equi-distant as
shewn in figures 5, 6 and 7 and removed therefrom by the forward motion of the
breech block B as it moves the cartridge from one of the chambers a, of the cylinder A
into the barrel of the gun and the prong ", is returned to the wall of the cartridge
so as to form a smooth surface.
The magazine K is designed to be worn upon the left breast of the person using the
fire arm and the cartridge on the end of the ribbon placed in one of the chambers of
the cartridge cylinder and a continuous supply is kept up until all of the cartridges on
the ribbon M have been used when another coil of ribbon and fixed cartridges is
placed in the magazine and the firing continued; the ribbon holder shewn in per-
spective view at figure 14 serves to keep the cartridge-carrying ribbon in position
against the cartridge cylinder while the cartridges are being brought into position for
firing, the ribbon holder being secured to the prong K' by two thread screws as shewn
in figure 4.
The several parts being constructed substantially as described the operation is as
follows:-
The magazine K having been filled with a coil of ribbon with the cartridges affixed
thereto and attached to the left side of the gunner the lever D is thrown forward and
the breech block B withdrawn from the cartridge cylinder; the cartridge on the outer
end of the ribbon is then placed in one of the chambers a, of the cartridge cylinder A
as shewn in figure 2. The lever D is then returned the cartridge moved from the
cylinder by the advancing breech block B and seated in the end of the barrel of
the gun with the extractor 13, engaged with the rim or flange on the cartridge; the
hammer 4, is set and the spring e, around the breech block compressed in the
chamber f¹.
The cam 11, is then moved into the position shewn in dotted lines in Figure 1 and
all of the parts assume their relative positions shewn in the said figure. The trigger g,
is then raised which releases the arm 7, from the latch 8, and the spring 10, throws
the hammer 4, forward which strikes the firing pin 5; and explodes the cartridge in
the barrel of the gun. The lever D is then thrown forward and by its movement it
first extracts the discharged cartridge and places it in one of the chambers of the
cylinder A; by this time the lever I will have carried the collar, on the sleeve i,
against the bearing or seat o, and the further movement of the lever will cause the
nut j, to engage with the worm gear h, and turn the pinion d, one third of a revolution
which will turn the cylinder A one fifth of a revolution and carry the discharged
cartridge to the right and place a fresh cartridge in the next chamber a, ready to be
inserted in the barrel of the gun.
The return movement of the lever D now pushes the cartridge out of the cylinder A
into the barrel and simultaneously therewith the arm 7, of the hammer 4; engages
with the latch 8, compresses the spring 10, and sets the hammer ready for the next
firing of a cartridge and the knife E is moved forward into the slot h', and cuts off the
end of the ribbon from which the former cartridge has been removed.
It will be observed that by the forward motion of the lever D the discharged
cartridge is withdrawn from the barrel, placed in the revolving cylinder moved out of
the way and a fresh cartridge placed in another chamber a, of the cylinder A in line
with the barrel and the return motion moves the breech block forward inserts the
cartridge, compresses the spring e, around the block and cuts off the free end of the
ribbon. In the description of the operation it is to be presumed that previously to
commencing work with the gun the cooling chamber I has been filled with liquid from
the reservoir J, and that during the use of the gun the supply of liquid is kept up by
the pump as the necessities of the case demand.
