Improvements in Magazine Fire Arms.
1. JOHN HAMILTON BROWN of the City, County and State of New York, United
States of America 162 East 36th Street, Manufacturer, 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 Magazine Fire Arms, and pertains to arms of that class
which are constructed to be used as single loaders or as repeating arms, at pleasure,
and the invention consists in the peculiar construction and arrangement of various
parts of the arm, all as hereinafter fully described and pointed out in the claims.
In the drawing forming part of this specification, Figure 1, is a side elevation
partly in section, of the frame of a magazine fire arm and portions of the barrel and
stock thereof embodying my invention, the operative mechanism of the arm in said
Figure, being represented in the position occupied thereby when the gun is closed and
loaded, and the hammer cocked. Figure 2, is also a side elevation of the frame and
portions of the barrel and stock of the arm but showing the guard-lever swung away
from the latter to open the arm sufficiently to eject an empty shell and bring the parts
to position to receive cartridges from the hand as in single loading, said Figure
showing the positions of various parts in dotted lines, all of which are hereinafter fully
described. Figure 3, is a plan view of the frame of the arm and of two levers
constituting connections between the breech-block and cartridge-carrier, which are
hung on a common pivot in said frame. Figure 4, is a side elevation of the front end
and the central part of said frame, one side thereof being broken away, disclosing one
of the inner walls thereof, the rear end of the frame being shown broken off.
Figure 5, is a perspective view of the breech-block, and Figure 6, is a central vertical
section of the same. Figure 7, is a plan view of the cartridge-carrier, showing
thereon in dotted lines the position of the cover thereof when the carrier is open to
permit cartridges to be inserted therein and pushed through it in order to load: the
magazine. Figure 8, is a perspective view of the cover of the cartridge-carrier, its
under side being shown uppermost. Figure 9, is a longitudinal section of a portion
of the upper side of the cartridge-carrier, showing in side elevation a pivoted cartridge-
stop and its spring. Figure 10, is a perspective view of the pivot-pin of the guard-.
lever.

page_text: In the drawing, 2, is the frame of the armi into the front end of which the rear end
of the barrel, 3, is screwed in the usual way. The fore-arm, 4, of the stock is secured
under the barrel by the engagement of its rear end with the adjoining end of the
frame, and by any well-known fastening devices. The butt, 5, is secured to the rear
end of the frame by the usual strap on the latter and a screw or screws passing through
the strap into the butt. An additional means for securing the butt to the frame is
afforded by the magazine-tube, 17, one end of which is screwed or otherwise secured
to the rear end of the frame, said tube extending rearwardly nearly to the butt-plate
and having a nut thereon (not shown in the drawing) within the butt which engages
with the latter and draws it endwise towards or against the end of the frame.
The construction, generally, of the within-described arm embodies a magazine-tube
in the butt of the arm to receive a certain number of cartridges: A cartridge-ejecting
spring within said tube having a pusher connected to one end, to move the cartridges
into the cartridge-carrier and through the latter into the barrel: A pivoted cartridge-
carrier located in the frame between the end of the magazine-tube and the rear end of
the barrel A guard-lever pivoted by one end under the frame of the arm and having
attached thereto the entire lock mechanism: A breech-block having a pivotal
connection with the guard lever and operating between the cartridge-carrier and the
rear end of the barrel, and a cartridge-shell ejector secured to the under side of the
barrel. The said arm constructed as below described, owing to the direct action of
the mechanism which conveys the cartridges from the magazine to the cartridge-
carrier, and to the action of the breech-block as the cartridge-stop when firing the
same as a repeater, is capable of using cartridges of varying lengths.
The guard-lever, 6, is pivoted to the under side of the frame, 2, of the arm by a
pin 15 (see Figure 10) which passes through the lower part of the forward end of the
frame and has a stud, 16, thereon which passes through a slot, a, at one side of the
pin-hole in the frame (see Figure 4,) and engages with the inner side of the frame at
that point when the pin is turned by the handle thereof after being put into the frame,
and thereby the pin is locked in the frame. By turning the pin back so that said stud
thereon corresponds in position with said slot, in the frame, the pin may be
withdrawn, thereby conveniently disconnecting the guard-lever and the lock mechanism
from the frame. This feature of construction enables one in case of emergency to
quickly disable the arm without the use of tools.
The hammer, 18, is hung between two cheek-pieces, 19, on the inner side of the
guard-lever on a pivot-pin passing through said cheek-pieces and the lower end of
the hammer the latter having thereon an arm, 20, which extends towards the forward
end of the frame and over a bar, 21, which extends transversely between the sides of
the frame under the barrel. The sear-notch is formed in the hub of the hammer, as
shown in dotted lines in Figures 1 and 2, and the nose of the hammer is constructed
to form of itself the firing pin. The main-spring whose position on the inner side of
the guard-lever is indicated in dotted lines in Figure 1, has its short arm bearing on
the upper side of the trigger, 22, and its long arm is connected to the rear side of the
hammer by the usual stirrup connection. By the above-described arrangement the
the main-spring serves both as such and as a trigger-spring.
A safety trigger-lever, 23, is pivoted in the guard-lever 6, at the rear of the trigger,
having one end engaging in a notch in the latter whereby the trigger is retained in
engagement with the sear-notch in the hammer when the latter is in a cocked position
as shown in Figure 1. The said safety-lever, 23, serves to prevent the accidental
operation of the hammer and the discharge of the arm until it is properly taken in
hand for that purpose, under which conditions certain of the fingers of the hand are
brought against the long arm of the lever, 23, at the same time that the finger engages
with the trigger, 22, and thereby said lever, 23, is, at the proper time, disengaged
from the trigger to allow the arm to be fired.
The guard-lever, 6, has a notch, o, transversely across the under side thereof just
back of its piyot, 15, which engages, with the edge of a bar 24, across the forward
end of the frame, 2, when said lever is swung downward to its greatest limit for the

page_text: purpose of operating the repeating mechanism of the arm, as below described, said
bar thereby serving as a stop for the guard-lever.
The guard-lever has a slot in its pivoted end in a plane with the adjoining sides of
the frame 2, in which slot an arm on the rear end of the ejector-trigger, 25,
extends as shown in Figure 1. A projection, v, on the end of the guard-lever projects
towards the under side of the barrel 3, and is adapted to engage with a downhanging
arm w, on the under side of the ejector 26, to aid in operating the ejector as
hereinbefore described. An arm, 27, on the guard-lever, 6, is adapted to engage with
a downhanging arm 28, on the under side of the cartridge-carrier, 10, as shown in
Figure 1, the engagement of said arm, 27, with the arm 28, serving to retain the
guard-lever in the position under the arm shown in said Figure, and the engagement
of said two arms one with the other also serves to cause the cartridge-carrier 10, to be
held up to the position shown in Figure 1, against the action of the spring 29,
located in a chamber in the butt, one end of which is attached to the latter, its opposite
end being connected to an arm 30, on the under side of the cartridge-carrier. Only
a portion of said spring is shown in the drawing.
The ejector 26, consists of a flat metallic bar on the under side of which is the
aforesaid arm, w, and it has a cylindrical tail-piece 31, extending towards the muzzle
of the barrel and passing through a stud 32, which is rigidly fixed to the under side
of the barrel 3, a nut or nuts being placed on the end of said tail-piece which engage
with said stud when the ejector moves rearward thereby governing said movement of
the latter. The rear end of the ejector passes under that part of the frame 2, into
which the barrel is screwed and the nose, z, of the ejector extends upwardly, as shown,
and is let in to a part of the frame and the under side of the barrel, as in Figure 1, so
that when it is retired against the barrel the outer side of said nose is in a plane with
the end of the latter. An inwardly projecting stud 33, is fixed on each of the inner
opposite sides of the frame and projects under the end of the ejector, the latter resting
and moving on said stud and being thereby held up to its position relative to the
under side of the barrel, thereby being prevented from springing out of place when
forced against the rim of the cartridge to eject it from the barrel.
An ejector-hammer 34, is placed on the cylindrical tail-piece 31, of the ejector at
the junction of said tail-piece and the aforesaid flat portion of the ejector, said hammer
being free to be moved longitudinally on said tail-piece, away from and towards the
abutment which is furnished by the end of the aforesaid flat bar portion of the ejector.
A lip, c, on said ejector-hammer extends towards the adjoining end of the frame 2, of
the arm, and the end of said lip is adapted to be engaged by the edge of the aforesaid
ejector-trigger 25. The said ejector-trigger 25, is pivoted between the sides of the
front end of the frame 2, just forward of the end of the guard-lever 6, as shown, a
spring 35, is secured by one end to said stud 32, under the barrel and its opposite end
engages with the under side of said ejector-trigger holding the outer end of the latter
in engagement with the end of said hammer 34. A spring 36, is placed on the said
tail piece of the ejector between the stud 32, and the hammer 34. The end. of the
lip, c, on said hammer 34, with which said trigger 25, engages has a notch therein.
running transversely across the end of said lip to receive the end or edge of said
trigger, said notch being more clearly shown in the dotted line representation of said
hammer in Figure 2, where it is shown disengaged from the trigger.
The operation of the above-described ejector mechanism in conjunction with the
guard-lever, 6, and the breech-block 9, is as follows:
;
Figure 1, shows in dotted lines the position of a cartridge in the barrel 3, after
the arm is loaded, the rim of said cartridge engaging with the nose, , of the ejector,"
and the ejector parts all in the positions which they occupy when the arm is dis-
charged. After firing the arm the guard-lever 6, is swung downward to the position:
shown in Figure 2, and in swinging said lever to that position the breech-block 9,
follows the guard-lever, as shown in Figure 2, clearing the end of the barrel and.
taking such a position that the ejector is free to act.
In swinging the guard-lever downward as aforesaid, the arm, v, thereon first
encounters or engages with the arm w, on the under side of the ejector thereby

page_text: causing the latter to move away from the end of the barrel and by a powerful lever-
action to start the cartridge from its chamber in the latter. A continued movement
of the guard lever brings the said arm on the trigger 25, into engagement with the
base of the slot in the end of said lever in which said arm projects, and thereby said
trigger is given a vibratory motion whereby the edge thereof which is engaged with
the end of the lip, c, on the hammer 34, is disengaged from the end of said lip and
caused to swing under the latter leaving said hammer free to be thrown suddenly by
the action of the spring 36, against said abutment end of the flat portion of the
cjector, thereby driving the latter suddenly rearward to the position shown in dotted
lines in Figure 2, and causing the cartridge-shell to be thrown rearward against the
top of the inclined cartridge-carrier and be thereby directed out of and away from
the frame of the arm. The cartridge shell when ejected forcibly from the barrel as
aforesaid, in its rearward flight inclines to strike one side of the upwardly projecting
finger-piece on the end of the cartridge-carrier cover 12, and is thereby so directed
laterally as to throw it away from the person holding the arm.
A cartridge being again placed in the barrel, the guard-lever 6, is brought
gradually to the position shown in Figure 1, thereby moving the breech-block, 9, up
behind the end of the ejector and causing the latter to move back under the barrel to
the position shown in Figure 1, and in so doing the hammer 34, is caused to move
n the same direction compressing the spring 36, meanwhile, between it and the
tud, 32, and bringing the end of the lip, e, on the hammer to such position that the
rigger, 25, will re-engage therewith, as shown in said. Figure 1.
The breech-block 9, illustrated in perspective and in sectional views in Figures 5
and 6, is pivotally connected to the guard-lever 6, by screws passing through slots in
its side as shown, (the hammer occupying a position within or between the sides of
said block as shown) whereby the breech-block is given or permitted a free oscillating
motion on said lever, and whereby said block is given a reciprocating movement
between the sides of the frame 2 directly back of the end of the barrel when said
lever is operated as above described. Said breech-block is adapted to form, in con-
junction with the frame, in which it operates as aforesaid, a solid, unyielding breech
at the rear of the barrel and of the cartridge contained therein, said block having,
during the latter part of its upward movement back of the barrel to close the same, a
motion at right angles to the end of the barrel, and it at that time moves within
grooves e, in the inner opposite sides of the frame 2 (see Figures 3 and 4) and the
edges of said grooves are so engaged with the rear side of the breech-block that the
latter cannot yield to any degree to the force of the charge so long as the frame
remains intact.
The rear edges of said grooves e, in the frame are inclined rearwardly at, f (sce
Figure 4) whereby said grooves are given a wider form near the lower edge of the
frame to accommodate said groove to the form of the sides of the breech-block, as
shown in Figures 5 and 6, the sides of said breech-block, when the latter is in the
position shown in Figure 1, substantially filling said grooves, and thereby the afore-
said rigid support is given to the breech block when the parts are in firing position
in the arm.
The upper end of the breech-block is inclined rearwardly, or towards the end of the
cartridge-carrier 10, to facilitate its action when lifted up against the end of said
carrier to bring the latter to the position shown in Figure 1. The breech-block is
provided with the central perforation, n, through which the nose of the hammer
passes to strike the primer in the end of the cartridge when the arm is fired. Two
slots, h, in the rear side of the breech-block in which the two arms of the bifurcated
lever 7, engage when the breech-block is carried to its extreme downward limit to
operate the cartridge-carrier as below described, are formed in said block as shown
in Figure 5.
The said lever 7, and the aforesaid lever S, have a mutual engagement when the
breech-block is moved downward as just described, whereby the free end of lever 8,
is caused to swing against the under side of the cartridge-carrier 10, and swing the
latter upward to bring a cartridge which it may contain into line with the bore of.

page_text: the barrel. This action of the levers 7 and 8, takes place when the arm is used as a
repeating fire-arm. Figure 2, shows in dotted lines the positions of the breech-block
when it is about to engage with and swing said levers 7 and S, and the position of
the cartridge-carrier when about to be acted on by said levers as above described.
The requisite extent of the vibratory movement (as shown in Figure 2) of the
guard-lever to load the arm for firing singly, is indicated to the operator by the
resistance caused by the engagement of lever 7, with the breech-block at the extent
of said movement, said lever acting against the tension of spring 29.
After the arm has been discharged the nose of the hammer is in a position behind
the breech-block or within the same to which it is carried by the action of the main-
spring when the trigger is pulled, and when the hammer occupies said position the
under side of the arm 20, thereon is brought near to the upper side of the fixed
pin 21, in the frame of the arm and the hammer becomes cocked again when the
guard-lever 6, is next swung downward by the engagement of said arm 20, with the
pin 21, whereby the hammer is swung to a cocked position so that the trigger can
re-engage in its sear-notch as before. When the hammer occupies a cocked position,
as shown in Figure 1, the extremity of arm 20, is carried a little higher than the
under side of the ejector, and to accommodate said movement of the hammer a
perforation is made in the ejector into which the end of said arm may enter when
said hammer is cocked.
The said cartridge-carrier 10, consists of a hollow block or cartridge receptacle of
the form shown in Figure 1, fitted between the inner sides of the frame, 2, and
having a strap J, extending rearwardly on the top of said frame, the extreme end of
which is pivotally connected with the frame, a slot K, being formed in the top of the
latter under said strap to permit the cartridge-carrier to swing on its pivot downward
to the position shown in Figure 2, or slightly lower, in operating the arm. As above
described the spring 29, serves to swing the free end of the cartridge-carrier down-
ward, but when the arm is loaded said free end is held in an upward position by its
engagement with the breech-block.
Figure 7, illustrates, in plan view, the outer side of the cartridge-carrier, an
opening D, being made therein to permit of the insertion of cartridges for loading
the magazine. At the rear end of said opening D, is a circular perforation in the top
of the carrier having one side communicating with said opening, a screw-hole x, x,
being formed near said circular opening.
A cover 12, for said cartridge-carrier has a boss d, on its under side, as shown in
Figure 8, on the ends of which are overhanging lips, as shown, which engage under
the upper side of the cartridge-carrier and retain the cover thereon, said boss con-
stituting a pivot connection between said cover and the carrier. The said boss is
concave in order that it may present no obstacle to the movement of cartridges
within the carrier. A screw is placed in the screw-hole, a, a, in the carrier at the
border of said cover 12, as indicated in Figure 7. When said cover is swung to the
position shown in dotted lines in Figure 7, it is stopped from further swinging
movement by said screw, and when the cover is swung back into line with the carrier
the end of the slot in the edge of said cover engages with said screw and stops the
cover at a proper position.
By removing said screw from the top of the cartridge-carrier the cover 12, may be
swung sufficiently around thereon to bring the said boss d, into a line with the
opening on the top of the carrier, and then the cover may be removed therefrom.
A cartridge-stop 13, is pivoted in a slot in the upper side of the cartridge-carrier,
one end of which is capable of swinging downward by the action of a spring 14, and
engage
with the rim of the cartridges when the cover 12, is swung open to insert
cartridges in the magazine, against the action of spring 37. Thus each cartridge, as
it is pushed into the carrier 10, and through the latter into the magazine, has its rim
caught by said stop and the cartridge is thus retained. When the cover 12, is shut
over the opening D, in the carrier it swings against the upwardly projecting end of
the stop 13, thereby swinging the latter to a line with the inner side of the carrier
and removing any obstacle to the free movement of the cartridges through the carrier,

page_text: except the breech-block 9. Figure 9, illustrates parts of two cartridges in said
operative relation to the stop, 13.
The said slot K, in the upper side of the frame 2, opens into a cylindrical passage
in the frame which communicates with said magazine-tube 17, and through which
the cartridges pass when put into or ejected from the magazine.
An ejecting spring 37, is placed in said magazine-tube 17 to one end of which is
attached a cartridge-pusher, 38.
Figure 9, shows the rim of one cartridge engaged with the end of stop 13, in the
manner described, and the end of another cartridge following the first one from the
magazine.
The sight 39, is of ordinary construction, excepting that it is pivoted by one end to
its bed and has a bubble-glass or spirit-lever 42, fixed therein, and a quadrant or
segment shaped arm 40, having graduation marks thereon as shown in Figure 1,
said arm being slotted, and a binding-screw 43, having a finger-piece thereon for
turning it, passes through said slot and screws into the side of said base. The
construction, and arrangement of said sight on the arm, affords unusual advantages
for firing the gun at excessive elevations for the purpose of dropping the balls upon
the enemy in warfare. By elevating the rear end of the sight, to, say 1000 yards,
more or less, as may be indicated by said graduation marks, and setting or holding
the gun by the level, it may be fired from the hip, or by resting the butt thereof on
the ground, with the result above mentioned. The upturned, rear end of the sight, 39,
is provided with the usual peep-hole or notch common in rear sights.
The operation of my improvements in firing said arm as a single loader, whether
the magazine be charged with cartridges or not, is as follows:
It being understood that the parts occupy the positions shown in Figure 1, before
beginning to fire, excepting that the hammer is not cocked:
In swinging the guard-lever downward the arm 27, thereon is disengaged from
the arm 28, on the cartridge-carrier, the hammer becomes cocked by the engagement
of its arm 20 on the cross-bar or pin 21, the breech-block is moved downward letting
the forward end of the cartridge-carrier drop, thus exposing the rear end of the
barrel, and the cartridge-ejecting mechanism is operated as above described. The
parts then occupy the positions indicated in full and in dotted lines in Figure 2.
A cartridge is then put into the barrel in the position shown in said last-named
Figure, with its rim engaged in the nose of the ejector. The guard-lever is then
swung up, the breech block following the guide of said grooves e, in the frame carries
the forward end of the carrier 10, upward, engages with the end' of the ejector and
the cartridge, sliding the ejector to its place under the barrel and forcing the cartridge
to its place in its chamber, and setting the ejector, mechanism as above described,
and re-engaging the said arms 27 and 28, when the lever is brought against the
under side of the arm. The trigger is then pulled and the arm is fired, and the empty
shell is ejected as above described.
To fire the arm as a repeater, the magazine being charged let it be supposed that
the parts have been swung to the positions shown in Figure 2, and that there is no
cartridge in the barrel: The guard-lever is swung still farther downward, causing the
breech-block to engage as described, with the lever 7, thereby oscillating the latter
and lever 8, and swinging the cartridge-carrier up into line with the bore of the
barrel. The cartridge then in the carrier is driven into the barrel by the action
of spring 37, the ball of the following cartridge resting against the head of the
preceding one. The guard lever is then swung up as before and the breech-block
and other operative parts of the gun are brought to the positions shown in Figure I,
ready, after firing the arm, to have said operation repeated.
It is obvious that the above-described mechanism which pertains to the magazine
and repeating features of this arm has no necessary connection with the mechanism
thereof which pertains to the single loading features of the gun, and therefore, the
latter-named features of construction may be embodied in a fire-arm entirely
independent of any repeating mechanism with the same advantages as they possess
in the construction herein shown and described.
