To all whom it may concern: l

Be it known that I, JOHN M. MARLIN, of New Haven, in the county of New Haven and State of. Connecticut, have invented a new and useful Improvement in Magazine- Guns, lof which the following is a specication.

My invention relates to that class known as magazine-guns;77 `rand it consists in certain improvements whereby the cartridges of such arms "maybe more readily introducedinto the magazine and delivered therefrom to the loading mechanism of the gun, substantiallyfas hereinafter described and claimed.

In the drawings, Figure lis a View of a portion of a magazine-gun, partly in section, provided with my improvement. larged view of thejmagazine loading-tube detac-hed from the magazine. Fig. 3 is a sectional view of the same. Fig. 4 is an enlarged is a view ofthe barrel and head ofthe loading-tube at theirouter ends.

Hitherto it has been found convenient to employ a cartridge-loading tube inside of the magazine-tube of the magazinegun, especially when'the gun is made of small caliber, the

loading-tube being capable of being charged andvinserted into the magazinemuch quicker than a like number' of cartridges can be in vserted directly into the magazine by hand.

A is the gun, madeof any well-known constructiomwherein the breechblock raises each cartridge successively from the level of the magazine to that of the bore of the barrel. b is the barrel ofthe gun. c is the magazineftube. d is a loading-tube inserted in the magazine#` tube from the forward end, and having within it a coiled spring, d', and a plunger, d2., to bear against the cartridges d3 d, placed within it, and press them successively into the breechblock as the charges are red.

When the loading-tube d is removed from the magazine to be filled with cartridges, it has been found difficult to confine the spring d in acompressed position to allow the plunger d2 to be pushed back as far as possible and give room for as many cartridges as the loading-tube will hold, and to hold it in this position and unlock it therefrom readily after the loading-tube has been inserted in the magazine, so as to allow the plunger and spring to deliver the cartridges into the loading mech- Fig. 2 is an en- Fig. 5

`[ anism in the ordinary manner. I provide a slot, e, extending longitudinally from near the open end ofV the loading-tube nearly to its closed end, where the slot terminates in al round hole, e', out through the side of the tube. A pin rectangular in cross-section, e2, is

formed with a screw-thread on its lower end, and of a proper thickness on its outer end to fill the slot e transversely, 'so as to preventits turning when in the slot. The greatest breadth of the upper end of the pin e2 is such that it is slightly less than the diameter of the hole e. Having inserted the coiled spring into the lloading-tubeagainst the internal surface of its closed end, I place the plunger di on top of it and press the latter down until a hole tapped in its side andprovided with aninternal screw-` 'thread to fit that of thepin e2 comes opposite to the hole e. I then screw the. pin e2 into the hole in the plunger a sufficient distance and bring its edge opposite the slot e, release the plunger, when'it is forced toward the open end of the loading-tube, the pin traversing the slot.

The pin being unable to turn in the slot thus secures the loading-tube and its, coiled spring andplunger together while in use, and at the in the tube until the pin is pressed out of the notch into the slot e again. These notches e3 e3 are-each placed so that when the plunger is locked by the pin into one of them, as before described, a certain given number of cartridges, when dropped into the open end of the tube and resting down against the plunger, will just iill the tube., The pin e2 projects a sufficient distance beyond the surface of the loading-tube to enable ktheplunger d2 to be readily pressed back and locked by hand from the exterior of the tube into one ofthe notches, as described.

The tube, being thus filled with cartridges,

.is inserted into the magazine from the front end, in the position shown in Fig. l, when it becomes necessary to unlock the plunger to ICO permit the spring to feed the cartridges into the loading mechanism of the gun. rDhis I accomplish in the following' manner: I press a portion of the magazine-tube c (preferably one of its edges where it is welded together) inward, thus, forming one or more shoulders, c, which come opposite the notches ai in the loading-tube when the latter is placed in the magazine. These shoulders c project inward far enough vto engage with the pin eL when the loading-tube is revolved in the right direction, so as to bring the pin against the shoulder, while the shoulders do not project inward far enough to prevent the loading-tube from being readily revolved in the magazine. Having inserted the loading-tube into the magazine, as described, I revolve the tube by means of the head end in 'the direction shown by the arrow in Fig. until the 'pin e2, coming against the shoulder c', is thrown out of its notch e3 into the slot e, and thus the spring d and plunger d2 are released from their locked position and operate to force the cartridges toward the loading' mechanism in the usual manner. i

The sam-e rotary motion of the loadingltube serves to lock it in the barrel in the :following manner: The barrel projects 'slightly beyond the magazine, and has a transverse 'slot cnt Vin its lower side of proper breadth to receive the head d4 of the loading-tube d. This head d* is milled on its 'exterior to aid in turning it inthe magazine by the fingers, -and on one side is cut voft" so as to allow it to pass the barrel and 'come opposite to the sl'ot last mentioned. This ycut-off' side serves not only 'to allow it to be pressed into the magazine vt'o this position, but also to show the position of the slot e ifn inserting the loadingtube intoy the magazine.

The revolution of the loading-tube, as before described, while it unlocks the spring and plunger, also brings the circular portion oi' the head of the tube d* into its slot in the A barrel and prevents its being withdrawn until it is revolved backward, so as to bring the cut-off side underneath the barrel.

When the loading-tube is inserted into' the magazine, in order to bring its open end to readily deliver the cartridges and afford the least friction possible, I secure a beILmOut-h 4 for taper-mouth collar, n, in the rear -end of 'the magazine-tube, which fits 'around the exterior of the end of the loading-tube 'd 'andi centers it properly vin the magazine at that.y end.

Instead 'of the shoulders c being 'made with their faces which abut against the pi'n e2 extending longitudinally of the magazine, they may be made with Itheir faces extending in a spiral direction around it, if desired, and

so that the act of inserting the cartridgeloading tube into the magazine in'alongitudinal direction will bring thel pin e2 against the spiral face of the shoulder and press the pin out of its retaining-notch in the loading-tube Without departing from the spirit of my invention.

What I claim as new and of my invention 1. The combination of the magazine-case c, provided with one lor more internal shoulders, c', with the longitudinally-slotted magazine d, provided with the spring d', its plunger d2, carrying pin e2, and one or more notches, e3, in slot e, with which said pin engages, substantially as described.

2. The combination 'of the magazine-case c, provided with one or more shoulders,rc, the magazine d, provided with the longitudinal slot e, and spring d', its plunger dl, carrying pin e2, one or more notches, e3, in said slot,

with which said pin engages, and the magazine-head di, adapted to lock itself i'n a 'correspondingslot in the arm by the rotary movement of the magazine, substantially as 'described.

3. The combination, with the magazine d, of the spring d', its plunger d, carrying pin e2, flattened on two sides, and slot e, in which it slides, having an enlargement, e', whereby the attene'd pin may be introduced int'o said slot, substantially -as described.

4. The combination, with the removable magazine d, lof the longitudinal slot e, spring d', its plunger d2, carrying pin e, and one lor `more notches, ei, in said slot, 'with which said pin engages, substantially as described.

5. The combination, with the magazined, of the spring d', its plunger d2, carrying the pin e2, flattened on one or more sides, and th'elon- Yg'itudinal slot e, in which it slides, having an enlargement, e,whereby the flattened pin may be introduced into said slot, and one or Amore notches, e3, insaid slot, with which "said pin engages, substantially ,as described.

6. Ihe combination, with a removable cartridge-magazine, of spring d, its plunger di,

l and suitable latch mechanism, which locks the plunger 'and spring back in the magazine-tube when the same is removed from the magazine, said latch mechanism being provided with a 'part projecting beyond the magazine to nnlock it, with one or more suitable attachments in the magazine-case, which autonratic'ally'engage with said projecting part of said latch and unlock the said latch mechanism by the i movement of inserting said tube into its place or seat in said case, substantially asde'scribed.
