Improvements in Magazine Guns.
A communication from HERMAN LEINE WEBER, of South Chicago, Illinois, United
States of America, Inventor.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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 :-
This invention relates to an improvement in the type of gun in which a spring-
controlled firing-pin is confined in a breech-block adapted to be reciprocated by
hand for the purpose of opening the breech for loading and closing the breech
preparatory to firing, the breech-block being further adapted to be rocked back
and forth on its longitudinal axis for unlocking and locking it.
"
The invention includes the provision with the aforesaid type of gun of a magazine
having an automatic feed for bringing the cartridges, in succession, to a position in
the breech in line with the bore of the barrel and into position to be pushed into
the latter by the return of the breech-block.
The object of this invention is to provide a gun, especially suitable for military
use, which shall involve in its firing mechanism a comparatively simple construction
and few parts, to the exclusion of springs, except one for the firing-pin and one for
the trigger, and to the exclusion of other or complicated details in the firing-
mechanism liable to get out of order or to become inoperative with use. As will
hereinafter appear, a single bolt. suffices for securing the entire firing-mechanism in
place in the gun.

A denotes the stock and B is the barrel. These parts need not involve any-
thing novel, but may be of any ordinary or suitable construction. The invention
is confined, entirely, to the mechanism interposed between the barrel and stock.
The breech C is formed by the two sides and 1. At the rear end of the
breech is the internally cylindrical housing or bearing C₁ for the breech-block,
hereinafter described; and where the barrel joins the breech-portion, the latter is
shown to be expanded, as represented at x, Figure 1, and internally cylindrical,
and is provided at the inner end of its bore with diametrically opposite notches v
and ¹, serving a purpose hereinafter explained. Near the forward end of the
housing in the base thereof is the breech-block lock D (see Figure 20) comprising
a rectangular block t fitting in an aperture formed through the base of the housing
and in which it may be raised and lowered, the extent of its play being limited,
however, by an elongated opening t¹ formed transversely through it and through
which, and the sides r and, a bolt t passes. On the upper end of the block is
provided a guide-stop for the breech-block, which guide-stop is formed, by
preference, of two studs or projections &, s, which, when the block t is raised to its
highest position, extend above the base of the housing C', but which, when the
block is lowered to the limit of its play, are flush with, or below, that base. For
convenience in manipulating the lock D a thumb-piece t is extended from the base
of the block t laterally beyond the side of the breech.
Immediately behind the lock D the interior of the housing C¹ is hollowed out
circumferentially, thereby forming the circumferential recess u, (Figure 1), from
opposite sides of which extend backward, longitudinally of the housing to the rear
extremity thereof, the lateral grooves u' and . From the circumferential recess u
the base of the housing is slightly concave longitudinally and centrally, as shown
at (Figure 15) and the extension of the said base behind the housing contains a
longitudinal central recess y¹.
E is the trigger, which is preferably formed of the peculiar construction
illustrated, though it is not intended to limit the improvement to the use of the
particular trigger-construction. The finger or lever portion p of the trigger is
fulcrumed at (Figure 1), whence it extends at one end beyond the under side
of the gun into the plane of the usual trigger-guard q. The other end of the
finger p extends into a chamber p², inserted into the base of the housing C
and having a longitudinally circular bottom on which is seated a block p', the
base of which is in the form of a segment of a circle fitting the base of the
chamber and with which the adjacent end of the finger p is rigidly connected.
The outer end of the segmental block p' is provided with an offset, and
projects normally through an opening in the longitudinal recess y' near the
extreme forward end of the latter, and above the plane of the base of the said
recess, the segmental block being maintained yieldingly in such normal position by
a spring o, one end of which bears against the inner expanded end of the block p

page_text: while the other extends into a notch w formed transversely in the back of the
block t of the lock D, whereby the tendency of the latter is to remain in its raised
position. To guide the segmental block p¹ and limit its play, elongated curved
openings p' are formed transversely through it; and through these openings, pins p*
extend from the walls or sides of the chamber p³.
F is the hollow breech-block, shown as of cylindrical form, and reduced in
diameter toward its rear end to form a narrower cylindrical extension F¹, which is
provided with a slot n formed transversely through it and extending to its rear end
and with L-shaped or "bayonet" grooves n' and n' extending respectively from
the forward end of the slot on opposite sides of the extension F₁, the bases of the
grooves retaining the circumferential concentricity with the exterior surface of the
extension. In the under side of the breech-block are formed, longitudinally of its
diametrically larger portion, the parallel grooves m and m² (see Figure 6) to
coincide, when the breech-block is in place, with the projections s on the locking-
block t.
The forward end of the hollow breech-block is closed by a disk-shaped
head 1, which may be screwed into place, as represented, and in the center of which
is an aperture l¹ formed in the shape of the head G¹of the firing-pin G, which
latter extends lengthwise through the breech-block considerably beyond the rear
end thereof, and should be threaded, as shown, toward its rear extremity and be
flattened just forward of the thread, as shown at w¹ on opposite sides. Inside the
breech-block the firing-pin is surrounded by a spiral spring G³, confined thereon
between the back of the head G¹ and a shoulder in the rear portion of the
breech-block. On the outer side of the breech-block F approximately opposite
that provided with the guide-grooves m, m³, is formed a longitudinal rectangular
recess m² containing a strip of spring-metal m³, fastened toward its rear end and
projecting beyond the forward end of the head l, where it terminates in an inward
projecting hook or catch; and a guide-flange for the spring-catch H, thus
formed by the parts me and 2, is provided to enter a recess³ (Figure 3) formed
in the base of the groove m' at the head 1. Directly opposite the hook 1, a tongue
projects forward from the periphery of the head ; and the exterior surfaces of the
tongue and the spring-catch H conform to the transverse curve of the cylindrical
breech-block, the spring-catch being flush, when in its normal position in the
recess m³, with the exterior surface of the breech-block. Immediately adjacent to
the tongue, a loosely reciprocating pink coincident with the groove m³ extends
through the disk-head liroin a recess or chamber ¹ formed back of the head lat
the end of the groove m', where a head k on the inner end of the pin projects
through the plane of the groove flush with the circumference of the cylindrical
breech-block.
I (Figures 12 to 14) is a cam-sleeve adapted to fit over the rear projecting end
of the firing-pin G and to form, as it were, a thickening of the end of the firing-pin,
and it reciprocates with relation to the reduced rear portion F¹ of the breech-
block F, with which it is adapted to interlock. To that end it is provided at
opposite sides with tongue-extensions.i, i, adapted to fit and slide in the opposite
sides of the slot n of the extension F¹ and embrace the firing-pin, which is prevented
from turning axially by the flattened sides of the bore in the sleeve, toward the
rear end of the latter, bearing against the flattened sides of the firing-pin near
its threaded end. On one side of the sleeve 1, at its rear end, is a cam I¹ facing
forward; and from the under side of the sleeve, also near its rear end, there projects
a stop. There is also provided, by preference, in the side of this cam-sleeve, at
a right-angle to the side on which the stop is provided, a depression or aperture ¿³
for engaging a safety-catch, hereinafter described.
K is the lock for the breech-block, the principal functions thereof being to set
the spring controlling the firing-pin preparatory to firing and without turning the
breech-block for the purpose; to lock the breech-block in the breech; and t
unlock the breech-block to permit its partial withdrawal preparatory to
reloading.
The detailed construction of the lock K. is shown in Figures 8 to 10, and a

page_text: description thereof is as follows: A cylindrical sleeve has a bore of a diameter
adapting it to fit over the sleeve I and reduced extension F of the breech-block;
and at opposite sides of the interior of the bore, at the forward end of the sleeve,
are tongues h¹, which, by sliding the sleeve upon the extension F, enter the
longitudinal portions of the L-shaped or bayonet grooves n', whence, by turning
the sleeve, they are brought into the transverse portions of those grooves to lock
the sleeve. Coincident with the tongues ¹ are ears 2 provided on opposite outer
sides of the sleeve h, which, as will hereinafter be more definitely described in
explaining the manner of adjusting the parts of the gun together, pass through the
longitudinal guide-grooves u¹ and 2 in the housing C₁, whence they enter the
circumferential recess therein, in which the sleeve is turned to remove the ears h³
from coincidence with the grooves u³ and ³, thereby locking the sleeve, (which as
will hereinafter appear, is fastened upon the breech-block) and the breech-block
against withdrawal. The rear end of the sleeve is notched, somewhat in the
form of a V, in its under side, toward the left thereof, to form an inclined face h*
in position to conform to the face of the cam I on the sleeve I; and at the outer
end of the inclined face is an offset h*, adjacent to which is a protuberance h³ on
the outer surface of the rear end of the sleeve h to afford a stop against turning the
sleeve, when the breech-block is in operative position, unduly toward the left.
K' is the handle extending about at a right-angle (with relation to the ears ³)
from the sleeve h, with which it may form an integral part, as shown; and it should
be provided, on its outer end, with the usual knob (not shown). Between the base
of the handle K¹ and stop his formed an opening g' adjacent to which is pivoted a
safety-catch g in a manner to extend its curved tongue-piece g' into the opening g',
with which the aperture in the sleeve I is caused, under certain conditions,
hereinafter explained, to coincide; when the catch may readily be turned up to
insert its tongue-piece into that aperture thereby to prevent accidental firing.
It should here be stated that the invention, as thus far described, may be used
for single loading, that is to say for inserting by hand into the barrel B a single
cartridge L at a time and firing it off; or with a supply of the cartridges in a
magazine M, adapted to feed the cartridges successively into position to be pushed
into the barrel preparatory to firing. A construction adapting the gun to be
readily interchanged for use as a single-loader, or as a magazine-loader, is illus-
trated in the drawings. Figure 19 shows the construction adapting the gun to the
first-named purpose, by providing in the inner face of each of the sides r and r¹ of
the breech, below the plane of the base of the breech-block housing C', a
longitudinal pocket of containing a spring-plate fl secured in place and bent to
extend at its free edge horizontally partway across the breech. The two spring-
plates thus nearly meet along the longitudinal center of the breech and form a
rest or table for a cartridge imposed upon them prior to pushing it into the barrel.
The plates are sufficiently yielding to adapt them to be readily forced back into
their respective pockets f by inserting the magazine, which, when it is adjusted is
partly held in place by the force of the spring-plates bearing against its opposite
sides.
The magazine M illustrated in Fig. 22 is of peculiar and very simple construction,
which adapts it for advantageous use with magazine-guns differently constructed
from that herein described; and the intention is, therefore, to avoid limitation to
the use of the magazine with this particular firing mechanism.
The magazine M, though it may be constructed of any of various materials, is
most conveniently formed by stamping, out of sheet-metal, a blank capable of being
bent into the shape of a flat chamber tapering in somewhat V-shape toward one
end, closed at its base and at both ends (which latter, however, are not fastened
along both edges to the sides, so that the sides are springy and may be spread
lightly apart) and extended at their upper edges, toward the rear, flaring, end of
the chamber into converging concavo-convex flanges e, e. At the rear end of the
flanges e the magazine is open to permit ready insertion, point foremost, of the
cartridges in filling the magazine; and as the converging flanges partly cover

page_text: the open upper edge of the magazine, they prevent forcing the cartridges upward
out of the magazine-chamber beyond the flanges e. The force which brings each
cartridge, in turn, between the flanges e is exerted automatically by a peculiarly
shaped spring-lever N (Figure 18), which may be best and most readily formed of
strong spring-wire bent double into the shape illustrated somewhat resembling a
double skate-runner pivotally supported, in the narrower end of the magazine-
chamber, at the extremity of its upward-turned end, the springy bowed portion d of
which projects through and beyond the forward narrower end of the magazine-
chamber, whence the longer part d' extends lengthwise in said chamber over the
base thereof. At the flaring end of the magazine a stop d² should be provided, for
a purpose hereinafter stated, and which may be stamped out of that end.
To adjust the several parts together the proceeding is as follows:
The trigger-chamber p², carrying the lock D, may be first adjusted in place, and
the bolt then inserted. It will be noticed that the bolt is the only bolt
employed in the entire mechanism for fastening parts together.
The breech-block proper F with its contained spring-controlled firing-pin, lateral
spring-hook H and reciprocal stud k, are not designed to be readily separated, but
are practically integral. Upon the breech-block is first to be adjusted the lock K
by slipping the sleeve over the breech-block extension F¹ in a manner to enter
the lugs into the grooves n' and n², till they reach the transverse portions of the
latter, into which they are turned. Then the sleeve I is slipped inside the sleeve /,
from the rear end of the latter, over the end of the firing-pin, and its tongue-
extensions i enter the opposite sides of the recess n in the extension F, while the
inner flattened sides of the rear end of the sleeve I embrace the flattened sides w
of the end of the pin G. This also brings the cam I against the inclined face h*
of the lock-sleeve h. A nut c (Figure 1) is then screwed upon the threaded
end of the firing-pin against the rear ends of the sleeves and I, securing them
against withdrawal from the pin G.
The next step is to adjust the breech-block and parts it carries into the breech.
To enable this to be done, the ears 42 on the sleeve must be in line with the
longitudinal grooves and u³, in the housing C', when the hook will be in line
with its notch e, while the arm K' must be turned upward to avoid obstruction by
an ear on the right-hand side of the extension of the base of the housing, and
between which ear and the rear end of the housing a recess is provided into which
to swing the handle K', as hereinafter described. To so turn the handle or arm K¹
the breech-block may be held firmly in the left hand and the handle manipulated
with the right. This operation, as will be observed, sets the firing-pin spring G³,
since it necessarily effects turning of the sleeve, whereby the inclined face his
moved against the cam I' until the latter is reached, at its base, by, and engages,
the offset ', whereby the sleeve I is forced outward, and, being confined by the
nut c, compresses, or sets, the spring G².
The breech-block may readily, then, be inserted end wise through the housing C',
(provided the block D has been lowered to take the projections s out of its path)
until its forward end strikes the rear end of the barrel B and the hook and
tongue, respectively enter the notches and . Thus adjusting the breech-block
likewise brings the stop on the sleeve into the groove ¹ to abut against the
upward projecting end of the part pl of the trigger; and a guide-tongue ² on the
lower side of the adjusted nut c also enters the said groove. With the stop i
against the trigger, as described, the arm K¹ may, with impunity, be turned down
to enter its recess, since, though the inclined face h will thereby be brought into
its normal coinciding position with relation to the cam I', (though in advance of
the latter) the spring G2 cannot exert its resilient force to advance the firing-pin,
Because the sleeve I is held back by the abutment of the stop against the trigger
in its path. To permit the resilient force of the firing-pin spring to act, the part p
of the trigger is pulled backward, thereby withdrawing the part thereof from
obstructing the action of the spring.

page_text: Of course the trigger is returned to its position, when released, by the spring o,
which is set by pulling the trigger.
To explain the operation of the gun, it may first be presumed that there is no
magazine provided, when, as hereinbefore explained, the spring-plates ex'end
below the plane of the base of the breech-block and afford a support for the
cartridge, insertion of which, of course, requires that the breech-block be first
withdrawn. To withdraw the breech-block, the arm K' is first raised out of its
seat or notch, thereby turning the lock K to bring the ears * coincident with the
longitudinal grooves u and u in the housing C, and at the same time setting the
firing pin spring. The breech-block may then be drawn out (or back), to open
the breech, until stopped by the projections s on the block D. Then a cartridge is
inserted thereby being in position to be pushed into the barrel, which is done by
advancing the breech-block to its closed position, in which the tongue and spring-
hook extend into their notches and in advance of the rim a on the rear end
of the cartridge, and clamp it yieldingly between them. On turning the arm K'
into its recess, the gun is ready to be fired, unless prevented by previous adjust-
ment of the safety-catch g to extend into its tongue-piece g² through the opening gl
into the aperture 3, in the sleeve I, then coincident therewith.
After firing, produced by pulling the trigger, the breech-block is withdrawn on
raising the arm K1, whereby, as will be noticed, the tongues enter the transverse
parts of the L-shaped grooves, thereby holding the sleeve as well as by the nut c;
and since the empty cartridge-shell is clamped between the catch and tougue 1, it
is withdrawn by the withdrawal of the breech-block, which likewise effects throwing
out of the breech the empty cartridge-shell, as follows: When the breech-block
has been so far withdrawn as to bring the head * cf the pink suddenly against the
stop m in the housing C, the pin k is suddenly forced forward against the rear end
of the cartridge-shell, thereby forcing the latter from between the tongue 1³ and
spring-catch H, the suddenness of the plunger-action of the pin k effecting the
discharge of the shell out of the breech.
If the magazine M be used, it is inserted, with its open end upward and tapering
end forward, through the base of the breech till the open rear end of the flanges e
is brought into the path of the breech-block F, (previously withdrawn to permit
the insertion) thereby forcing the spring-plates f¹ (if provided) backward into their
pockets. It should be stated that the magazine is to be supplied with cartridges
prior to adjusting it in place, wherein it is stopped from a tendency to rise by the
projection d² bearing against the adjacent end of the trigger-guard q. The weight
of the cartridges rests on the spring-lever N, bearing the latter down against the
base of the magazine-chamber, and, consequently, protruding the bowed portion of
the lever through the forward end of the chamber. When, however, the magazine
is adjusted in place, into which it closely fits, the end-walls of the receptacle for it
being rigid, the bowed end of the spring-lever N is necessarily forced inward,
thereby creating considerable tension on the long arm of the lever, and a tendency
in the latter to swing upward to relieve the tension. This, however, it cannot do,
because the force of the spring-lever is insufficient to separate the flanges e by
pressing against them the cartridges from below. The breech-block, however, on
its return-movement, pushes the uppermost cartridge in its path between the
flanges e into the barrel, spreading the flanges e apart, in so doing. Thus when the
breech-block is closed it is in the position of the cartridge it displaced in closing;
but when it is again withdrawn, another cartridge is raised into its path by the
spring-lever N.
The firing, withdrawal and throwing out of the empty shell, and other operations
are the same with the magazine as without it; and having been explained with the
last-named condition, they need not again be described with the use of the magazine.
As will be understood, when a magazine has been emptied of its supply of
cartridges, it may be removed by merely pulling it out, to permit the insertion of a
filled one.

page_text: The minuteness of the foregoing description is considered at least advisable. for
the sake of clearness, but is not intended to create the impression that all of, or the
exact, details are indispensable parts of the invention, which is believed to be
generically novel as to certain broad features. Among these are particularly to be
inentioned the locking of the breech-block by a rotary lock independent of the
breech-block, whereby the latter may be locked and unlocked without being turned
on its axis for those purposes; the interchangeable construction with which the
gun may be provided to adapt it for a single-loader or a magazine-gun; the
construction of the magazine itself, which, as hereinbefore mentioned, may be used
with advantage with other forms of firing-mechanism than that herein described;
the thorough locking of the breech-block in the breech, and also the holding effect
upon the locking-sleeve by the bayonet-grooves in the breech-block extension, for
which holding effect the nut c need not be relied on; and the peculiar construction
of the trigger-mechanism, which, as in the case of the magazine, adapts it for use
in other guns.
