MAGAZINE BOLT-GUN.

SPECIFICATION forming part of Letters Patent No. 601,842, dated April 5, 1898.

Application nea June 20,1895. Serin No. 553,493. (No man.)

T0 LZZ whom t may concern:

Beit known that I, SAMUEL N. MCOLEAN, a citizen of the United States, residing at Washington, in the county of Washington and State of Iowa, have invented certain new and useful Improvements in Breech-Loading Firearms, of which the following is a specification.

My object is to improve and simplify the construction of breech-loading and magazine firearms, to provide cam-guides which shall control both the action and combination of the parts, to provide a barrel-feeding mechanism, to provide a safety firing mechanism, and to provide certain novel details of .construction and combinations hereinafter more fully set forth.

My invention when regarded in the entirety of its parts may be briefly described as follows: a cartridge-magazine carrying its cartridges in file, a reciprocating slide engaging the foremost cartridge in the magazine and connected to a reciprocating handle to draw the cartridges from the magazine into the receiver, a reciprocating breech-bolt, a connecting medium between said bolt and a reciprocating handle, the said medium partially encircling the bolt and having a cam-guide to actuate, reciprocate, and lock the bolt, a breech-bolt having a reciprocating and rotating movement, a firing-pin carried by said bolt, the rotating movement of the bolt bringing it into the path of the ring movement of the pin, a carrier movable between the barrel and the magazine and actuated to grip and release the cartridge by a handle having a wedge-shaped end movable between the gripping-arms of the carrier, a cartridge-magazine carrying its cartridges in file and having a spring-actu ated follower and provided with a scale to indicate the number of cartridges in the magazine, a carrier-feeding slide, a dog connected to a reciprocating handle and controlled by said slide to engage with and be disengaged from the carrier-feeding mechanism, a sear engaging the firing-pin and tripped by the handle to discharge the weapon, and a firing mechanism engaging both the pin and the handle and actuated by the trigger to release them.

The description of my invention with the accompanying drawings is as follows:

Figure 1 is a longitudinal sectional View of the barrel and stock of the firearm, showing the operating parts of the weapon assembled. Fig. 2 is a longitudinal section of the breechbolt and firing-pin. Fig. 3 is a front end view of the same. Fig. 4 is a side elevation of the handle, showing the carrier cam-track. Fig. v5 is a transverse or cross section of the same. Fig. 6 is a section of the magazine, showing the follower C and the slide C6 to open the magazine. Fig. 7 is an elevation of the bolt and ring-pin, showing the cam shape of their respective ends. Fig. 8 is a detail of the carrier-feedin g slide or track, showing the slot D2, in which the spur D is moved to-cut off the magazine. Fig. 9 is a section through the receiver, showing the carrier; Fig. 10 is a,

plan View of the part H, showing the cam-slide for operating the bolt and the'shape of this trackl to permit the. firing movement of the handle. Fig. 11 is a longitudinal sectional View of the weapon with the operating-parts assembled in forwardposition. Figs. 12 and 13 are detailed views of the cartridge-carrier. Fig. 14 is a horizontal sectional view taken through the weapon on a line with the under side of the part H, showing the cam-track H5 and the dog T and the manner in which the dog T engages with the side wall to actuate it`to release the pin H4, which connects this slide H5 with the breech-bolt. This View, Fig.

14, shows the straight part of the'groove H5 at its forward end to permit the carrier-lifting showing the dog T and groovefH5 and the concave upper surface of the part H to permit it to partially encircle the bolt. Fig. 17 is a plan view of the handle, showing its wedge-shaped forward end. f

A is the frame, in which the side walls of the receiver areformed to be alike on either side of the openings through which the cartridge is received and the shell ejected, and thefront end of the receiver is provided with Iool helical-shaped lugs at opposite points of the l `compass to engage the breech-bolt and to receive the strain of the discharge on the line of greatest strength and limit it to the least possible area of the frame to take it direct and to distribute it equally on all parts of the frame.

C is the cartridge-magazine, preferably located beneath the stock-frame and carrying its cartridges in tile and having a spring-actuated cartridge-follower C' and a scale and slot C2 to indicate the number of its contained cartridges.

The cartridge-follower C' has a pin-and-slot connection With the frame by means of the slots C5 and C7 and has a slide movement to open the magazine for the purpose of loading.

K is the actuating-handle controlled by the guard R to traverse a course on the under side of the stock and having a carrier-actuating track K', which has a double or diamondshaped forward end.

I is the carrier, having gripping-arms and engaging with the handle by means of the part I and pin I2 and its forward end shaped t'o conform to the size and contour of the cartridge. The cam or beveled faces I3, Fig. 12, of the carrier I are located in the path of the movements of the handle and are engaged by it to actuate the carrier to grip and release the cartridge.

E is the breech-bolt, Figs. l, 2, and 7. It is movable in a chamber formed on a line with the bore of the barrel and is provided with cam-lugs E' near its forward end to engage With corresponding cam-lugs A in the receiver. It has both a reciprocating and rotating movement and is connected to the reciprocating handle by means of the part H. This part H, Figs. l and 10, partially encircles the bolt and is provided With a cam-track to reciprocate and lock the bolt, the cam part of the track causing the bolt to rotate and the straight part of the track permitting the ir- H2 is a link connection of the parts H and K. G' is the track in which the extractors move and which tracks converge toward the bore of the barrel to canse the extractors to grip and release the cartridge.

G is the cartridge-extractors, attached to a collar which encircles the bolt. formed to be guided in the tracks G and to bear against the bottom of these tracks.

F is the firing-pin, Figs. l, 2, and 7, movable in a chamber formed in the breech-bolt and having a cam-shaped part to engage With a corresponding cam-shaped end on the bolt,

They are as seen in Fig. 7. The projecting cam-lug F6 on the firing-pin engages with its companion notch E2 on the breech-bolt, and the lug F4 prevents the firing-pin from rotating and permits a rotating movement of the breech-bolt to bring the lug F6 into line with its companion notch E2, as seen in Fig. 7 of the drawings,thus permitting the full firing movement of the ring-pin only when the breechbolt is in its locked position, the rotating movement of the bolt bringing it into line with the complete firing movement of the firing-pin. The iiring-pin F is actuated by the spring F2, which is set by the rearward movement of the bolt and is provided with a lug F4 to prevent the rotation of the firing-pin and the notch F5 to engage with the Sear L.

The automatic sear L is pivotally attached to the frame, as seen in Fig. 11, and projects into the path of the handle and is disengaged by the pin K2 of the handle to discharge the Weapon.

H is the carrier-feeding dog, which is pivotally attached to the part H and is provided With a pivot which slides in the track H3, which controls the carrier-feeding action of this dog and the handle.

The scar P, Fig. l, engages with the tiringpin and with the trigger M and is disengaged from the firing-pin to discharge the weapon by the action of the said trigger. The trigger M also engages with the notch K3 on the handle to lock and release the handle.

The slide D, Figs. l and 8, is located in the groove D3 (see Fig. ll) in front of the foremost cartridge in the magazine and has a hook-shaped forward end to engage with said cartridge and a hook-shaped rearward end to engage the dog H. This part D is also provided With a pin or button D', which projects through a suitable slot (not shown) in the frame, having a direction parallel With the groove D3, (see Figs. l and 11,) and by means of which the part D can be drawn forward by hand out of the path of the dog H', thus cutting off the magazine.

When the operating parts are in the position illustrated in Fig. l and the handle is actuated to move forward, it causes the pin l2 to traverse the groove K and the carrier to descend to position in front of the magazine. At the same time the part H is driven forward, and the lock T, being in engagement With the pin H4, causes the breech-bolt to advance till this lock T comes in contact with the cam side Walls of the receiver, which moves the lock T out of engagement with the pin H4 at a time when the cam-lugs E' have passed into position in front of the cam-lugs A' of the receiver, and by the further movement of the handle the part H causes the pin H4 to traverse the cam-guide H5 and rotate the bolt to locked position. The pin H4 then traverses the straight part of the guide H5 and permits the tiring movement of the handle. The dog H', when the bolt moves forward, is guided by the rear part of the slide H3 until IOO IIO

the hooked extremity of this dog has passed beyond the rear end of the carrier-feeding slide D, at which time the cam shape of this track Il3 causes the dog H to descend into engagement with the slide D and to pass forward beyond the rear end of this slide D until it has moved forward sufficiently to complete the locking and firing movement of the handle and to advance the slide D till it will permit the cartridge-follower C to feed the cartridges up into the path of the rearward movement of the slide D, as shown in Fig ll. The reverse or loading movement of the parts is as follows, the handle and breech-bolt being then in their forward orxlocked position and the carrier in position in front of the magazine, the handle being also in locked engagement with the trigger M by means of the catch K3: The trigger M when used is actuated to release the handle by the finger, and the rearward movement of the handle causes the part H to be drawn back and the pin H4 to traverse the cam-guide H5, thus causing the rotating and unlocking movement of the bolt, the further backward movement of the bolt withdrawing or extracting the shell and bringing the dog H into engagement with the slide D, and the further backward movement of the handle causing this part D to draw a cartridge from the magazine into the grip of the carrier at the same time that the shell is bein g extracted from the barrel. The cartridge, when it has passed from the magazine fully into the carrier, is actuated to rise into line with the bore of the barrel by the pin I2 of the carrier traversing the double or'forward end of the groove K in the handle K, thus lifting the carrier to position in front of the bore of the barrel. The part D, when it passes through this forward position, permits the action of the follower C and spring C4 to lift the succeeding cartridge into the path of the movement of this part D. The slide D is provided with a spur D', which projects through the slot D2 in the stock-frame and is operated to move the slide D out of engagement with the bolt and cut the magazine out of action. This spring-actuated follower C has a pin-andslot connection with the magazine-frame by means of the slots C5 and C7, which slots permit the pin-spur C3, which projects through the side of the magazine, to be slid back, thus openin g the magazine for the purpose of loading. The slot C2 permits the vertical feeding movement of the follower C and is provided with a scale to indicate the number of cartridges contained in the magazine.

The operation of the safety mechanism is as follows: The tiring-pin traverses a iixed path of movement and does not partake of the bolts rotation, and when in its rear position it is engaged by the sears L and P, the spring F2 being then compressed. The breechbolt when it moves forward traverses a straight course until it reaches the limit of its forward movement, and when actuated to rotate into locked position the cam-face E2 and the lug E3 are turned until they pass beyond the corresponding cam-lu g on the lringpin, thus bringing the bolt into the path of the complete movement of the iiring-pin and permitting the pin,when released by the sears L and P, to travel forward until it causes its front end to protrude through the bolt and encounter the cartridge to discharge it. The reverse or unlocking movement of the bolt causesthe cam or helical shaped face E2 and i F4 to slide past each other, thus starting the firing-pin back, drawing its point out of contact with the primer and cartridge and making it impossible f or the pin to hit the primer until the bolt has been rotated into locked position.
