COLUMBIA FLANOGRAPH CD..WASHINOTON. DIC- AUGUST O. SOI-IILDBAGH, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO THE MARLIN FIREARMS COMPANY, OF NEW' HAVEN, CONNECTICUT, A CORPORATION OF CON- NECTICUT.

To all whom it may cancern L' Be it known that I, Aoensr C; SOHILD- BAOH, a citizen of the United States, residing at New Haven, New Haven county, Connecticut, have invented certain new and useful Improvements in Cut-Offs for Magazine- Guns, of which the following isa full, clear, and exact description.

This invention relates to an improvement in cartridge cut-offs for tubular magazine guns, particularly of the type set forth in the J. H. Wheeler Patent No. 94:0,764 of November 23rd,1909. 7 Q

In the accompanying drawings, Figure 1 is a side elevation of a tubular magazine gun with the breech open and partlybroken away to illustrate the cut-off mechanism; Fig. 2 is a section of'certain parts on the plane of the line w-m, showing the cut-elf mechanism in one position. Fig. 3 is a similar view showing the same parts in another position. Fig. 4 is a perspectiveview of a detail of construction. 'Fig. 5 is a per-- 5 spective view of another detail of; construc-' tion.

1 represents the stock of a gun'.

2 represents the barrel- 3 represents the bre'echj' frame or receiven carrying appropriate breech mechanism including a carrier 5. t V

6 is a tubular magazine arranged underneath .the barrel 2 and provided with the usual spring-pressed follower (not shown) by which'cartridges contained in the magazine are forced rearwardly toward the receiver so that they may be successively admittedtherein at the proper time.

8 is an action rod of the usual type which enters the receiver and may be reciprocated to and fro by means of the usual handle which ordinarily slides upon the magazine (SJ This action rod 8 may be operatively connectedwith the breech mechanism within the receiver in any suitable manner, for

example, as shown in the aforesaid Wheeler patent.

9 represents a cartridge within the magazine.

10-11 represent the two parts of the cut: off'mechanism which, as in the aforesaid Wheeler patent, are located in a recess in the same side of the gun as the action rod 8 and just below the action rod so that the cut-off mechanism may be operated thereby.

CUT-OFF FOR MAGAZINE-GUNS.

Specification of Letters Patent. v Patented Jun 9, 19j 4 Application filed December 26, 1913. Serial No. 808,728.

12 is a pivot pin for the parts 10-11 upon which these parts rock in a horizontal plane. At the forward end of each cut-off part 1011 there is a stop abutment as shown respectively at lO 11 The stop 10? pro- Jects slightly ahead'of .the stop 11. The stop part 11 carries an arm 11 which pro- ]ects into the path of a cam shoulder orincline 8 on the action rod so that when the Faction rod 8 is slid rearwardly it will directly encounter the extension 11*. and positlvely operate the cut-0E member 11. In

this instance the positive operation is in a direction to retire the stop 11 from the'path of the cartridge about to be moved into the t A spring 11 maybe employed to tilt the part 11 in the opposite direction when the action rod 8 is moved ahead to such a degree that the cam incline 8 lifts the shoulder 11*.

Thus far described, the various parts of "the cut-01f mechanism and the cooperating action rod correspond with the same parts set forth'in the aforesaid Wheeler patent.

The present improvement has for its 0 ject the provision of means whereby the action rod cam incline 8 may also assist in operating the other section 10 of the cut-off mechanism. To that end I provide an upwardly extending shoulder 10 onthe part 10*, in this instance forward of the pivot 12 and this shoulder likewise extends into the path of movement of the cam incline 8 so that when the action rod is moved back,

said incline 8 will engage the shoulder 10 and push the stop shoulder 10 into the cartridge cutting off position. I also pr0- vide at the rear of the cut-off part 10 a spring 10 for operating in opposition to the cam incline 8 so that when the action rod is'drawn ahead, the cutting off part 10 will be tilted and the stop 10 withdrawn from the path of the cartridges in the magazine. In the preferred construction I provide the cut-0fi part 10 with a bevel 10, the incline of the bevel being on the upper edge so that in the event the spring 10 should fail to tilt the part 10 in a direction to retire the stop shoulder 10 then some part of the breech mechanism may engage said 'mclinelO and positively repress the stop shoulder 10 In operation, when the action rod 8 is fully advanced, as shown in. Fig. 3, the stop 10 will be retired, allowing the rearmost cartridge 9 in the magazine to pass. At this time, however, the stop shoulder 11 will stand in the blocking position so that the cartridge in the magazine will be held in the position shown in Fig. 3. When the action rod 8 is moved rearwardly, the cam shoulder 8 will first engage the extension 10 and project. the stop shoulder 10 into the path of the next following cartridge in the magazine, the stop shoulder 10 being suitably shaped to extend around the rim of the cartridge which is then being held by the stop shoulder 11". As the action rod 8 is moved farther back, the cam incline 8 engages the extension or shoulder 11 as shown in Fig. 2, so as to tilt the cut-off sec tion 11 and withdraw the stop shoulder 11 from the rear of the cartridge being held thereby, thus allowing the follower spring to force that particular cartridge back into the receiver, as indicated in dotted lines, the next succeeding cartridge being stopped by the stop shoulder 10, as shown in Fig. 1. When the action rod is advanced to carry the cartridge now on the carrier5 up into position in front of the breech block for insertion into the chamber of the-barrel, this forward movement of the action rod will first withdraw the cam incline 8 from behind the shoulderll whereupon thestop shoulder 11 will be projected by the spring 11 into its cartridge-engaging position. When the action rod is moved far enough ahead. the cam incline 8 will be withdrawn from behind the extension 10, whereupon the spring 10 will tilt the cut-off section 10, withdrawing the stop shoulder 10 from the cartridge, allowing the cartridge to move back against the then projected stop shoulder 11*, as shown in Fig. 3.

It will be observed that by this unique construction of two-part cut-off mechanism, which parts are independently controllable, I am enabled to employ a single cam shoul der 8* on the action rod for operating both of said parts in the proper time and sequenceto permit cartridges to be effectively and reliably fed, one by one, from the magazine into the receiver.

What I claim is:

1. In a repeating firearm, a receiver, a tubular magazine opening into said receiver, a cartridge cut-off, including two independently movable stop elements adjacent the opening from the magazine into the receiver, one of'said stops being arranged slightly in adyance of the other, a reciprocating action rod with integral means carried thereby for positively engaging and moving each of said stop elements alternately.

2. In a repeating firearm, a. receiver, a tubular magazine opening into said receiver, a cartridge cut-off including'two independent pivotally mounted stop elements arranged side by side, means for operating one of said elements from one end to withdraw the stop abutment thereof from the cuttingoff position, and means for operating the other element from the same end to withdraw the stop abutment thereof from said cutting-off position.

3. In a repeating firearm, a magazine, a receiver, said magazine opening into said receiver, a cut-off comprising two independently movable pivoted parts arranged side by side, each part having a stop shoulder at its forward end, one of said stop shoulders being located in advance of the other, an action rod and means operated thereby for positively projecting the forward stop abutment into the cartridge cutting-0E position.

4. In a repeating firearm, a magazine, a receiver, said magazine opening into said receiver, a cut-oil" comp ising two independently movable pivoted parts arranged side by side, each part having a stop shoulder at its forward end, one of said stop shoulders being located in advance of the other, an action rod and means operated thereby for positively projecting the forward stop abutment into the cartridge cutting-off posit-ion, said means operating the other part to positively withdraw the stop thereon from the cutting-off position.

5. In a repeating firearm, a magazine, a receiver, said magazine opening into said receiver, two independent cartridge cut-0if stops arranged adjacent to the opening from the magazine into the receiver, an action operating device directly engaging and positively operating both of said cut-off parts independently. i

6. In a repeating firearm, a magazine entering the front of said receiver, a cutoff mechanism comprising two independent tilting parts arranged on one side of the receiver, a stop shoulder on each part forward of the fulcrum for each of said parts respectively, one of said stop shoulders being located in advance of the other, an action rod having a cam incline, a projection on each of said cut-off parts arranged in the path of movement of said cam incline, one of said projections being forward of the fulcrum of one part, the other being to the rear of the fulcrum of the other part, whereby when said action rod is reciprocated, said cam incline will engage said projections respectively and successively and positively tilt each of said parts, with means for tilting said parts in opposition to the tilting movement produced by the action of said cam incline.

7. In a repeating firearm, a receiver, a tubular magazine opening into the front end of the receiver, a cut-off magazine including two independent tilting members pivotally mounted intermediate their length, a stop shoulder at or near the forward end of each of said tilting members, one stop to positively repress the stop shoulder at shoulder being arranged in advance of the the forward end thereof, with means inde other, a reciprocating action rod having a pendent of the action rod for moving each cam incline, said cam incline engaging the of said tilting members in opposition to the 5 tilting member having the most advanced movement imparted thereto by said cam 15 stop shoulder at a point forward of its i incline.
