UNITED STATES PATEN JOHN SABO, OF CLEVELAND, OHIO.

AUTOMATIC MAGAZINE.

To all whom it may concern:

Be it known that I, JOHN SABO, a citizen of the United States, and resident of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Automatic Magazines, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to provide a magazine for a quick firing rifle or other gun, in which the cartridges can be delivered endwise, and in which a multiple number of cartridges can be stored without jamming them together and from which they can be delivered one at a time in quick succession with absolute precision, and regularly until all have been used.

The objects are further to provide simple, eflicient and automatically acting mechanism for delivering the cartridges to the gun so that no further effort will be required on the part of the operator than sighting the gun and pulling the trigger, all the operating parts being designed to move in their regular order without further attention.

The invention consists in a series of cartridge storage tubes comprising a storage cylinder which is rotatable about a common axis, a conductor or guide tube leading from and in line with one of said storage tubes, automatically operating mechanism for ro tating the cylinder through the diameter of one tube at the moment of delivery of the last cartridge from one of the storage tubes; means for pushing the cartridges one at a time from the tubes, means for pushing out the cartridges remaining in the conducting tube, and also, consists in the inclosing case for the tubes, and in the forms of construction and arrangement of details and combination of elements or organized parts as hereinafter described shown in the accompa nying drawings, out in the claims.

in the accompanying drawings Figure 1 is a longitudinal section of a gun showing and specificially pointed the arrangement of the magazine and con ducting tube therein, for forward feed of the cartridges; Fig. 1 is a similar view of a repeating gun showing the arrangement of the various parts, adapted to rear feed of the cartridges; Fig. 2 is a longitudinal section Specification of Letters Patent.

| of the magazine chamber or case, showing the series of storage tubes therein, which comprise the magazine cylinder, the actuating spring by means of which the storage tubes, are revolved about their common axis, and the springs adapted for delivering the cartridges and the cartridge followers; Fig. 3 is an end view of the magazine showing the ratchet mechanism and detaining pawl therefor, and an automatic device for releasing the detaining pawl, and also an exterior pawl or cartridge detent adapted to prevent the delivery of the cartridges when the magazine is removed from the gun: Fig. 4 is an end elevation of the magazine, the end wall of the casing being removed, showing the slotted retaining ring and plate for the cartridge followers: Fig. 5 is an end view of the storage tubes or cylinder showing the supporting plate slotted for the passage of the lugs which operate the pawl releasing device: Fig. 6 is a perspective view of the outlet tube fixed upon the end wall of the magazine casing with which the storage tubes are designed to register in turn; in this View are shown the automatically acting devices for engaging the pawl with the ratchet teeth upon the magazine cylinder, one tooth for each storage tube so that the cylinder can be rotated by its spring, and also shows mechanism for operating the detent which retains the cartridges within the delivery tube. These two mechanisms are connected together in such a manner that when the said detent is down the pawl which is adapted to engage the ratchet teeth can not be thrown into engagement therewith, Fig. 7, is a bottom view of these devices; Fig. 7 is an enlarged view of a portion of the same, Fig. 8 is a perspective view of the sleeve upon the projecting outlet tube and the cam thereon which operates the aforesaid cartridge detent; Fig. 9 is a longitudinal section of the upper part of the cylinder and case, showing the mode of operation of the pawl and ratchet device which retains the cylinder; Fig. 10 is a perspective View of the axial shaft upon which the storage cylinder is mounted, and the slotted terminal cup shaped plate therefor to which the supporting plate for the storage tubes is secured, and Fig. 11 is a longitudinal section of the reach rod employed in one of the tubes, and adapted to force the last remaining cartridges into the gun, Fig. 12 is a side elevation of one end of the detached cylinder; Fig. 1.3 is a transverse section showing the main operating spring.

In these views, 1 is the magazine case, 2 the storage tubes which are supported by means of the disks 3, 3 concentrically upon a common axial shaft 4, and comprise the storage cylinder, which may be designated I as a whole by the letter C. This cylinder is rotatable within the case in terminal shaft bearings 5, 5.

6 is a short combined feed outlet tube secured to the end wall or cover 7 of the magazine case 1, and designed to register in turn with the storage tubes 2, 2, as the cylinder rotates, within the case. Each tube 2 is provided with a follower 8, which is provided with a lug 9, extending through the longitudinal slot 10, in the tube. The cartridges are fed to these tubes in turn through the short tube 6, until all are full, and are retained therein by the end wall 7 except in one tube which registers with the outlet tube 6, and a detent 11 pivoted upon a sleeve 12 thereon retains the cartridges in this tube until the magazine is put into place in the gun.

A strong spiral spring S is employed to rotate the cylinder through a distance equal to the space between the centers of the tubes. To limit this movement a pawl 13, pivoted upon the case at 14 is normally in engagement with one of the ratchet teeth 15 upon the periphery of the cylinder and prevents its movement while each tube is being emp tied of its contents. It is essential that the movement of the cylinder should be an automatic intermittent one, and that the movement thereof should take place as soon as each storage tube has been emptied of its cartridges. To accomplish this action of the device, the lug 9 on each follower 8, is adapted to engage with a sliding bar 16, mounted in the wall 7 of the case. The movement of this bar is conveyed to the pawl 13, to place it in position to release one of the ratchet teeth, by means of the link 17, bell crank lever 18, having an engaging arm 19, a sliding bar or rod 20, and a lever arm 21, upon the pivot rod 14 of the pawl, so that every time one of the followers engages the inner inclined end of the bar 16 the pawl will be raised out of contact with its corresponding ratchet tooth, until the last cartridge has passed out of that tube, when the cylinder will be free to turn, and the lug will slide off from the sliding bar 16. Immediately a spring 22 will return the pawl, so as to cause it to engage the next ratchet tooth in order and detain the cylinder from further movement.

The axial shaft is secured to the cylinder by means of the disk shaped head 23, thereon which is provided with a rim 24. Both disk and rim are slotted longitudinally at 25, 25

to permit of the passage of the lugs 9, 9, and a terminal solid portion 26, retains the lugs in place so that they will not shoot out of the cylinder. This disk is secured to the supporting disk 3 by means of screws, 27, 27, so that all parts move together and the outer disk 3 is slotted radially at 28, 28, for the passage of the lugs 9, 9. This construction permits of the removal of the shaft and followers when desired.

The cartridge detent 11 is depressed by means of an integral spring 30 when released and is raised by means of the cam 31 upon the sleeve 32, rotatable on the outlet tube. This sleeve is rotated by means of the finger operated lever 33, secured thereto and is connected by means of a link 34 with the longitudinally movable bar 20, hereinbefore described, and when the lever 33 is moved this bar 20 is moved sidewise as shown in Figs. 7 and 7 until its outer end 35 is in engagement with the lever arm 19, which operates the bar 20 and through its agency the pawl 13. The movement of the lever 33 has no direct effect upon the movements of the pawl 13, since the spring 22 serves to normally retain the pawl in contact with one of the ratchet teeth upon the cylinder. But the movements of the lever 33 serve to throw the bar 20 into and out of line with the operating lever 19, so that the lever 19 operated by the sliding bar 16 and lug 9 can not release the pawl 13 when the cartridge detent 11 is down.

The sliding bar 20, is provided with an inclined extremity 35, shown upside down in Fig. 7 and 7 This extremity when the bar is thrown outward, (as seen in Fig. 7 and in Fig. 7 in dotted lines) will engage the inclined face F on the rock arm 19, and hence the lever 18 and arm 19 will not move the bar forward when the lug 9 engages the slide 16, but when the bar 20 is thrown in as shown in solid lines in Fig. 7 the arm 19 will engage the bar and move it forward. A guard plate G shown in Fig. (i serves to retain the extremity of the bar 20.

In Fig. 11 is shown a reach rod 50 in two portions jointed at 51, one part being slidable within the other and provided with a modified form of lug 9 at one end. This reach rod is placed in the last tube to be used, and will force the cartridges out of the conducting tube L which leads to the gun. A spring 52 makes the result more easily obtained. This device is substituted for a follower 9 in the last tube only.

In Fig. 12 is shown the extremity of the cylinder and numerals therein as shown one for each tube adapted to show through an opening 41, in the case serve to indicate what storage tube is in use at any time, and in this manner will indicate how many tubes have been used.

In Fig. 13 the main operating spring S is shown. This spring'is housed within a cylinder or case 43 and the case is provided with a lug 4L2 wherebythe rotary pressure of the spring is transmitted to the cylinder.

This lug can be placed between any two storage tubes 2, 2, and hence the pressure of the spring can be made adjustable at pleasure.

In Fig. 1 the cylinder case is shown detachable from the gun stock by means of lugs, T which enter the stock and a recess M, is engaged by one half of a pin N, which can be turned around half way to release it. The shoulder piece for the stock is preferably formed of aluminium and projects downwardly so as to be in line at its lower edge with the edge of the case 1, and in this manner it protects a projecting handle 60 by means ofwhich the shaft 4: can be rotated when filling the magazine with cartridges.
