Improvements in Magazine Guns.
I, HARRY KIDDER WHITE, Lieutenant of Marines, U.S. Navy, at present
stationed at Washington, D.C., U.S.A. do hereby declare the nature of my
invention for IMPROVEMENTS IN MAGAZINE GUNS, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The gun is improved as to the construction of the barrel, stock, breech mechanism,
automatic mechanism for loading, mechanism for cooling the parts, and in the
magazine, the cartridge feeder, and in various details.
Fig. 1 is a partial side elevation of a gun, showing the open breech mechanism
and magazine in section, and omitting the automatic loading devices.
Fig. 2 is a broken top plan, and Fig. 3 a broken longitudinal sectional plan of the
bolt.
Fig. 3 is a cross section of bolt and trigger.
Fig. 4 is a plan of the locking slide, and Fig. 5 a cross section of the gun just in
rear of the locking slide.
Fig. 6 is a broken detail elevation and partial section just in rear of the
magazine.
Fig. 7 is a front view of the bolt, and Fig. 8 a cross section at a-a, Fig. 3.
The gun barrel has a housing 1, extending back continuous with the receiver 2.
The housing 1 has a mortise 3. extending into or through its walls.
The holt A, or the shell thereof, is in two pieces. The piece 11 constitutes the
nose and body of the bolt, and has a firing pin 12 passing through it, and an extractor
attached to it. The extractor has a hook 14, which engages the flange of the
cartridge. The rear end of the extractor is merely a book or turned down end,
which end drops into a recess in the nose of the bolt, to connect the extractor to
said bolt.
The bolt has a cover 15, to which the handle 16 is attached. This cover 15, has
a longitudinal movement with reference to the nose piece 11, and may be held to
said nose piece either by a longitudinal tongue and groove, or by one part being
inclosed partly in the other, or by one part lying on top of the other, the housing of
the gun holding them together when the bolt is in place.
The nose piece 11 has a transverse mortise 9, in which the locking piece or
slide 20 rests.
The locking slide 20 is as long as the transverse diameter of the
bolt, plus the thickness of the walls of the housing 1.
One side of the housing has
a slot 4 leading back from the mortise through the end of the housing. This slot is
not as high as the height of the mortise.
The slide piece 20 has a groove along one or both of its faces, parallel with its
surface, forming a neck 21.
When the slide piece is shifted to the left, as in dotted lines, Fig. 5, the narrow
or thin neck 21 comes opposite the slot 4 in the frame, the end of the slide projecting
to the left of the housing. The other end of the slide is drawn into the bolt, and
as the neck of the slide is drawn into line with the slot 4, the bolt may be moved
forward or back in the housing, the neck 21 of the slide piece passing through the
slot 4 in the housing.
When the bolt is closed the slide piece may be pressed to the right, as in full
lines Fig. 5. The ends of the slide piece then enter the mortise 3, on each side of
the housing, and fit snugly therein, thus locking the bolt against rearward
movement.
The movement of the locking slide transversely of the bolt is effected by the
movement of the bolt cover 15, as follows: The slide piece 20 has an upwardly

page_text: projecting pin or lug 22. This pin enters a cam groove 19 in the bolt cover, (dotted
lines as Fig. 2). A backward pull on handle 16 moves the bolt cover 15 to the
rear, and the cam groove 19 engaging the pin 22 moves the slide piece to the left,
thus unlocking the bolt. As soon as the bolt is unlocked, a continuation of the
rearward movement of handle 16 causes the end of the cam groove 19 to engage the
pin 22, and pull the slide piece along with the bolt cover. The slide piece, resting
in its mortise, draws the nose of the bolt back with it. A reversal of this movement
of the handle presses the bolt forward and locks it. Thus the bolt is opened, closed,
and locked by a movement of the handle exactly in a straight line parallel with the
receiver. The locking piece is supported in both sides of the frame or housing, and
the bearing surfaces are about transverse to the frame.
By inclining the faces 24 of the locking piece slightly, and the ends of the
mortise 3 to correspond, a powerful wedging action is brought to bear on the bolt
nose, both in locking and unlocking, so that the cartridge may be forced home in
the chamber, or "started" in withdrawing.
The
The front hook 14 of the extractor engages the shell in usual manner.
extractor guard 26 rests in a groove in the top plate of the bolt, and has an
independent lengthwise movement, and its front end rests over the extractor when
the bolt is closed, holding the extractor firmly to the cartridge. The guard is pressed
forward by shoulder 27 in the bolt cover engaging the rear end of the extractor
guard, as the bolt cover makes its final forward movement.
As the bolt cover 15 is drawn back in opening the breech, the guard 26 is held
from backward movement by the friction spring 13, in the rear housing 8, bearing
on said guard, until the bolt nose is drawn back, when the guard is carried back
with the bolt nose and extractor by means of a slot and pin connection between the
extractor and guard. When the bolt is drawn back the lower edge of the cartridge
flange strikes the ejector 30, to throw out the shell.
When the bolt is closed the spring 13 engages a notch 29 in the extractor guard,
and holds the same back until a shoulder on the cover strikes the guard to move it
forward. This holding back of the guard permits the extractor to spring over the
cartridge flange.
The receiver and housings are slotted to receive the projecting end of the slide 20
when the bolt is unlocked. The slide piece 20 has inclined recesses 31 and 32 in
its rear edge, one of these recesses being deeper than the other, and the firing pin
has an incline 33 in position to enter one of these recesses, as the firing pin is
pressed forward by its spring 34. The recess 32 is deep enough to permit the pin
to spring forward and strike the cartridges, but the recess 31 is not deep enough, so
that the firing pin can only move forward to firing position when the slide 20 is in
position to lock the bolt.
As the gun is fired the incline 33 enters recess 32. The first movement in
unlocking causes the incline 32 to press back the firing pin, and hold it back until
the bolt is again locked. The incline 33 then enters recess 31 and holds the slide 20
to the left in moving the bolt. The firing pin may be of usual construction. By
preference I attach a handle or hammer 36 extending behind the bolt and this may
be used to draw back the firing pin by hand. Notches 37 in this handle or hammer
may be engaged by a sliding catch 38 on the rear of the bolt cover, so as to hold
the firing pin in safety or cocked or half-cocked position. The firing pin is caught
by the sear 40, and released by pull on trigger 41, as usual.
The parts of the bolt are assembled entirely without screws. The end of the
hammer or handle 36 has a recess to receive the head at the rear of the firing pin,
and the spring surrounding said pin has a bearing against the body of the bolt and
a collar on the pin, as usual. The slide piece 20 enters the mortise in the bolt, and
binds the parts together, the incline 33 on the firing pin holding said slide piece in.
By compressing the spring 34 the slide piece may be withdrawn from the mortise in
the bolt, and the bolt then withdrawn from the housing.
The magazine 50 is open at the bottom for the passage of a cartridge holding clip
or packing case 51, which clip or case incloses only the body portion of the

page_text: cartridges. The follower 52 on which the bottom cartridge rests, is pressed up by
a spring 53, which spring is partly outside the magazine, and enters a slot at the
front of the magazine. The follower 52 may have a guide 54, which extends
through a curved slot 55 in the side of the magazine and keeps the follower in
proper position for feeding the cartridges.
The clip or packing case 51 is struck up from elastic sheet metal. The sides of
the clip, near the top and bottom and rear edge, are slotted as indicated at 58, and
the part of the metal between the top and bottom slots forms a spring catch, 59,
which is bent in to clasp the cartridge heads. The spring tongues 58 are formed
by a second slot near the top and bottom of the clip. These tongues bend inward
and then outward, their ends forming an inclined catch which will spring outward
and permit the top cartridge to be pushed forward. (See Fig. 6.) All the
cartridges may be inserted in the clip from the front thereof at one operation, and -
will be held by the bent-in edge of the metal engaging the cartridge heads, and by
the spring tongues.
When the bolt is drawn back, the open ended clip may be put into the top of the
magazine, either end of the clip upward. The lower cartridge in the clip will press
the follower down, placing the spring under tension, and in general the rim of
the upper cartridge will extend slightly into the pathway of the bolt, so that as the
bolt moves forward it will push the cartridge forward. The tongues 58 hold the
flange of the top cartridge from moving forward, until pushed out by the bolt, and
the inturned upper edge of the clip holds the cartridge down until it has moved
forward out of the clip, when it will be moved into the chamber of the gun, as is
usual in this class of guns, the next cartridge taking the place of the first and so on.
As the top cartridge rises in the clip it is pressed slightly forward by the inclined
or turned in corner 475, Fig. 10, the clip, being tilted by the preceding cartridge,
still in the receiver, thus carrying the rim of the top cartridge past the rim of the
one below, should it have been behind the same.
The clip 51 has a lug 60 on its rear side. A pawl 61 at the rear of the receiver
has a toe 62 which engages said lug when the clip is in the magazine.
The pawl 61 slides vertically, and is held by friction. The toe 62 yields to let
the lng 60 pass, and then engages the top of the lug. The upward pressure of the
follower on the bottom cartridge tends to lift all the cartridges and clip, but this toe
holds the lug down.
If desired to reserve the magazine, using the piece as a single loader, the pawl 61
may be pressed down, by the finger of the operator acting on button 64, and the
button may be caught below the tooth 65, in the rear housing 8. This depresses
the clip so that the cartridges will not be moved therefrom by the bolt movement,
and cartridges may be fed singly into the receiver, the top cartridge in the magazine
acting as a floor to the receiver. When button 64 on pawl 61 is disengaged from
tooth 65, the follower will lift the clip to make the magazine operative.
The pawl 61 may be used to expel empty clips or packing cases from the
magazine should the clip fail to fall by gravity when empty. The pawl 61 may
be lifted out of engagement with tooth 65, when the abutment 99 in the frame will
press back the pawl and permit the clip and its cartridge to be lifted out of the
top of the magazine, by the force of the spring follower, or otherwise.
The stock B will be of such construction as to receive the working and other
parts of the gun.
I have described this gun in a simple form. I will now describe the modifications
by which it may be made automatic, and I will further describe the mechanism for
cooling the barrel, and other modifications and improvements.
The parts corresponding to those in the non automatic firearm are hereinafter
designated with the same numerals heretofore used, with the number 100 added;
or numeral 1 prefixed; other parts are usually numbered from 200 upward.

Fig. 22 is a section of air pump.
The gun barrel is rigidly connected to the receiver 102, which is rigid with
housings 101 and 108. The transverse mortise 103 in the housings, is transferred
to the rear housing, and the mortise in the bolt is carried back to correspond.
The receiver 102 is carried in guide ways 201 attached to the stock, so that said
receiver and all its connections may have a longitudinal movement in said guide
ways. The barrel is mainly covered by a casing in which it may move longi-
tudinally, as hereinafter described.
The receiver has a rigid downwardly projecting arm 202. This arm is connected
to a plunger or piston 203, around which plunger there is a spring 204. The
backward movement of the barrel and receiver under influence of the recoil is
opposed by this spring 204, (and other resistance as will be described,) and as the
barrel recoils the recoil compresses this spring 204.
As soon as the force of recoil is exhausted, the spring 204 forces the barrel and
receiver forward, to their firing position, Fig. 10. The bolt is opened or held
back as the receiver moves forward, by mechanism about to be described.
The bolt 1 has a transverse locking slide 120, with a projecting pin 121. This
pin is engaged by the cam plate 215, the pin projecting into the inclined slot 219
in the plate. The cam plate 215 has an arm 217 extending down at the side of
the gun stock.
A spring pressed pawl 220 has one end projecting from the side of the stock,
and extending into the path of travel of the arm 217. The nose of this pawl is
inclined, so that it may spring inward to let arm 217 pass by when carried back
by the recoil, and will then spring out and retain said arm. (See Figs. 9, 10, 11.)
When arm 217 is thus held back, and the barrel and receiver are pressed forward
by spring 204, the bolt will be opened, precisely as if the cam plate 215 (which
answers to bandle 16, and its cover, 15, Fig. 2,) had been drawn back and the
receiver held stationary, as in Fig. 1. That is, the bolt and its locking mechanism
will be held back as the barrel moves forward, thus opening the breech, and the
shell or cartridge will be extracted from the barrel by the extractor.
A small cylinder 230, attached to the stock, has a spring 231 inclosed therein.
A piston rod 232 connected to this spring, extends behind arm 217 before described,
and has a hook 233 which may be tuned over so as to engage the rear edge of
said arm.
When so engaged the recoil of the barrel and receiver will draw out
the piston rod 232, and compress spring 231, and when arm 217 is held back by
pawl or catch 220 this spring will be under tension. By releasing catch or
pawl 220 the spring 231 will draw the piston forward, and with it the arm 217,
and the bolt and its locking mechanism, and by the lengthwise movement of
plate 215 the locking slide 120 will be caused to enter the mortise 103 in the
housing, as soon as the bolt is closed.
The magazine 150 is in the stock, and feeds its cartridges upward through a
hole in the bottom of the receiver, said hole in the receiver being over the
magazine when the receiver is in its forward position.

page_text: A swinging gate 240 is pivoted near the front of the magazine. This gate has
an inclined surface 241 projecting slightly over the bullet of the top cartridge in
the magazine. A pin 242 projects from one side of this gate, and a draw rod 243
has a slot 244 therein, which the pin 242 enters. The draw rod extends back,
and has a hook 246 behind the end of pawl 220. The spring 245 which presses
out this catch or pawl, causes the rod 243 to swing the incline 241 over the bullet
of the top cartridge. When the bullet rises it swings the gate 240, which draws
on rod 243, and releases the catch 220, thus permitting the spring 231 to draw
the bolt to closed position and lock it. Gate 240 has a slotted connection with its
pivot, so that it may rise slightly as well as swing on its pivot..
The arm 202 on the receiver carries a catch 250, which is guided in ways on
said arm. This catch has a bevelled end 251, which is pressed up into the recess 252
in the frame or fixed slide way, when the receiver is in its former position, by the
trigger spring 253. The lower end of the catch 250 may have a hook or pin 254
which is engaged by a corresponding hooked leaf or projection 255 from the
trigger spring, to pull down the catch 250 when the trigger is pulled, thus disen-
gaging the catch from recess 252, to permit the recoil of the barrel and receiver
which thus can only occur when the trigger is pulled.
The trigger 141 is shown connected to a sear or catch 140 by a link 140*.
To enable the clip 151 to be entered into the magazine from below, the spring
and follower must be moved out of the way. The follower 262 is secured to the
coil spring 263. A forked lever 264 is connected to the other end of said spring.
This forked lever lies alongside the magazine, and the outer end 266 of one fork
projects through an inclined slot 265 in the wall of the magazine, said magazine
being wide enough at its forward end for such purpose. The stock in front of the
magazine has a recess. By pressing the handle 266 forward in the slot 265, the
lever, follower, and spring will be carried forward into this recess.
The clip
containing cartridges may now be inserted in the magazine without resistance from
the spring
In drawing back the handle 266 the end of the follower rides under
the cartridges, and the spring is brought under tension as the handle rides up the
incline. The other fork of the lever has a turned-in edge 269 which projects over
the edge of the clip, and serves to expel the clip when the handle 266 is pressed
forward. The casing or stock may have indicating marks alongside the slot 265,
and the follower is visible through the slot, thus indicating the number of cartridges
in the magazine. The handle may be moved forward to said marks, when the
follower will be partly depressed in the magazine, and the number of cartridges
designated may be dropped into the magazine.
The magazine may have a guide groove 158 (Fig. 15) in which the cartridge
heads will be guided, when it is desired to enter cartridges independently of
the clip.
Should the extractor fail to withdraw the shell or cartridge, it is desirable that
the magazine be stopped, so that no more cartridges be fed therefrom. To this
end a bearing piece 270, hung to spring 271, (Fig. 15,) is placed where the rim of
a cartridge will rest thereon when the cartridge is in its chamber in the barrel.
This presses the piece 270 against the inclined front face of gate 240, and holds
the incline 241 of said gate back over the end of the bullet of the upper cartridge
in the magazine. The withdrawal of the cartridge shell E permits the spring 271
to raise piece 270 and then gate 240 may swing, to operate the pawl 220.
A key 295 in the stock may be turned to engage a projection 296 on the draw
rod 243, and thus hold said draw rod permanently forward, the slot 244 permitting
this movement. The pawl 220 will then be held out of engagement with bar 217,
and the breech will move forward with the barrel after the recoil, when it must be
opened and closed by hand. The gun thus ceases to be automatic.
To cut off the magazine entirely, so that the gun may be used as a single loader,
a feed stop 280 is provided. This stop is the section of a ring, and is supported in
a recess or groove outside the receiver. When this stop is up, as in Figs. 10

page_text: and 14, the magazine is free to feed.
When turned down, as shown in the section,
Fig. 18, the lower part of the ing section lies over the mouth of the magazine,
and prevents the rise of cartridges therefrom. The natural action of introducing
a cartridge, in using the gun as a single loader, will turn down the stop so it will
act as a cut off. When tuned up it is full view of any one observing the gun,
and an officer in charge of troops can readily see whether the magazine is used, or
whether the piece is used as a single loader.
The lever 264 has an upwardly projecting pawl 290, which engages a spiral
groove 291 in the magazine cut off, as said lever moves forward, in the operation
of filling the magazine. This turns the cut off so that the gun becomes a single
loader. In returning lever 264 the pawl rides out of groove 291, and does
not open the cut off, so the cut off must be opened by hand before the magazine
can feed.
The plunger 203 is hollow, and closed at its end. When the barrel recoils this
piston or plunger enters the hollow cylinder 283, into which it fits closely, and the
air is compressed in the cylinder, thus forming a buffer or recoil check to the
backward movement of the barrel. When the plunger 203 has entered cylinder 283
a sufficient distance, it strikes a ring valve 284, and moves this valve back, against
the pressure of spring 285, and opens ports 287, letting out the compressed air,
which may be used for cooling the gun, a suitable pipe conveying the air to the.
barrel.
As plunger 203 moves forward, a vacuum is created in cylinder 283 until the
plunger passes out, thus serving to ease the forward movement of the barrel on
return from recoil.
The barrel 310 has a covering C secured to it, leaving a space between. This
cover moves with the barrel on recoil. A pump cylinder D is secured to this
and partakes of its movement. This pump cylinder contains a piston E,
which fits tightly in the cylinder, and the piston rod F is connected to the stock B
of the gun.
cover,
The pump cylinder has inlet ports 300, governed by suitable valves to permit
the inflow and prevent escape of air, and has pipes or passages 301 leading to the
space between the barrel and cover. Thus each reciprocation of the gun barrel
causes the pump to force air into the space surrounding the barrel.
The gun barrel 310 may be corrugated or coarsely screw threaded on its surface,
as at 311, to make a large radiating surface; or the same object accomplished by
winding the barrel with spiral wire; the outer surface retaining the spiral wind.
Saddles 313, made to fit the cover and the corrugations of the barrel, are inter-
posed between the cover and barrel. Screws 314 may hold the cover to these
saddles, and also secure the sight 315 to the barrel.
An outer casing H forms with the stock an inclosing covering for the front part
of the gun barrel, and casing C enters this outer cover at least as far as the length
of the recoil movement.
The stock B, under the barrel, will have longitudinal or circumferential spiral
grooves 320, for double purposes of permitting a passage of the air, and of affording
less surface for contact between the barrel and stock.
The front end of cover H is a hollow cylinder, and the front end of the barrel
has ribs 325 which center the barrel in this cylinder, and permit the passage of
air between said ribs. There is an annular orifice O formed around the muzzle
between the cover H and barrel. The rapid passage of gases on discharge past
this orifice, causes a vacuum in the space about the muzzle, drawing the heated air
out around the muzzle and the fresh air in at the breech around the barrel to
cool it. The front sight 326 is attached to one of the ribs 325 and projects
through a slot 327 in the covering, thus serving as a guide to the front of the
barrel. As the bayonet cannot well be attached to this sight, which moves with
the barrel on recoil, a catch 328 may be applied to the side of the casing, and the
bayonet secured to said catch.

page_text: An abutment 440 connected to the stock or slide way may have a rubber buffer
attached, to take the shock of the forward movement of the barrel under the
impulse of spring 204.
The firing pin 340 projects at the rear of the bolt, and may be cocked by hand
if desirable.
The bolt may be operated by hand as follows: A thumb piece 350 has a spring
clasp 351 connected thereto. A short pin 352 extends from the thumb piece into a
hole in the arm 217 when the thumb piece is clasped to said arm. A downward
pressure on the outer end of the thumb piece will spring the clasp 351 so that the
pin 312 will be withdrawn from the hole in arm 217, and the thumb piece can thus
be removed.
A spring pin 353 in one side of arm 217 projects through loops 354 and 355,
when the thumb piece is attached to arm piece 217. This spring pin fills these
loops, which project from opposite sides of the clasp. But when the thumb piece
is in its forward position, as when the breech is closed, a horn 357, permanently
attached to the stock, engages the end of the pin 253 and pushes in said spring
pin, the horn then extending through the loops. The horn 357 is smaller than
the spring pin, and does not fill the opening in the loops, so that the spring
clasp may be opened, and the thumb piece detached from aim 217. (See Fig. 23,
which is an edge view of thumb piece with clasp opened.) Fig. 22 is a similar
view with clasp rigid. Fig. 24 is a broken face view of thumb piece connections.
In Fig. 15 the barrel and its housings are shown in section, and a bevelled
guide piece 444 shown in tear of the barrel, to guide the cartridges from the
magazine into the chamber.
