6 tiliaims. (Ci. 42---17) This invention relates to automatic, semi-automatic and slide actuated firearms in which a tubular. magazine'is mounted below the barrel. Cartridges housed in the tubular magazine are fed one at a time into the receiver of the firearm by a pair of novel cutoffs mounted in the receiver and controlled by a pair of slide arms. The slide arms may be actuated by the manipulation of a manual slide or automatically by a gas piston mounted in the front of the magazine tube or other means.
Prior art devices are known in which a pair of cutoffs is mounted in the receiver of a firearm and spring biased inwardly on opposite sides of'the mouth of a tubular magazine to control the movement of cartridges into the receiver. Young, Patent 955,490; Swebilius, Patent 1,550,758; and Crittendon et al. Patent 2,719,375 disclose such an arrangement. arrangement of cutoffs mounted in the receiver on opposite sides of the mouth of a tubular magazine. One of the cutoffs being normally spring biased inwardly into the path of movement of the cartridge and moved outwardly by cam means. The other cutoff being normally spring biased outwardly and positively movedinto the pathof movement of the cartridges by cam means. This novel arrangement of cutofis provides a degree of positive control over the movement of the cartridges from the magazine tube to the receiver which was heretofore impossible with the known prior art structures. The novel arrangement of elements disclosed in this invention eliminates jamming of the gun action. which frequently occurs when States Patent 0 This invention provides a novel wardly biased position. As the second cartridge is released by the first cutoff, it moves rearwardly a very slight distance until the rim of the cartridge comes into engagement with the second cutoff. The operation of the slide arms is then repeated the receiver. 1
It is apparent that at the moment each cartridge in the magazine is moving the greatest distance under the most force; .there is a cutoff positively held in its path by a cam. This feature eliminates completely any danger of the cartridge merely biasing the cutoff outwardly out of its path and bypassing the cutoff.
Thepreferred embodimentof this invention will now be described in detail with reference to the accompanying drawingsin which: p

so that the cutoff on the right is moved inwardly behind.
the rim of the first cartridge in the magazine tube.
FIGURE 4 is a sectional view similar to FIGURE 3 fin which the slide arms have been reciprocatedrearwardly a cartridge prematurely bypasses a cutoff, as frequently 7 occurs in the known prior art devices.
In the preferred embodiment of thisinvention. a first and a second cutoff are mounted in the receiver of a firearm on opposite sides of the mouth of a magazine tube.
ward of the first cutoff. As the cartridges are loaded into the magazine tube, the rim of the first cartridge engages the second cutoff which is positioned in its path. Thev first cutoff at this point being normally spring biased out of engagement with the cartridge. A pair of slide arms mounted above the cutoffs are then actuated to selectively feed the cartridges from the magazine into the receiver. Each slide arm is provided with a cam to engage a cam follower on the respective cutoffs. Rearward movement of the slide arms causes a cam on a first slide arm to. engage the first cutoff and move the cutoff inwardly be,- hind the rim of the first cartridge. Further rearward movement causes a cam on the second slide arm to engage the second cutoff and cam it outwardly out of engagement with the first cartridge. The first cartridge is then free to move rearwardly into the receiver. The rim of the second cartridge in the magazine moves into engagement with the first cutoff which has been positively cammed inwardly. Since there is a positive cam force on the first cutoff, there is no possibility of the cutoff being forced outwardly by the engaging force of the second cartridge; thereby, allowing the cartridge to slip by the cutoff and jam the gun action. The slide arms are reciprocated rearwardly to the end of their stroke vand then brought far enough to cam the left-hand cutoff out of the path of movement of the first cartridge. v

Referring now to the drawings: FIGURE ,1. shows a cut-away view of a firearm having a receiver 1. A barrel 2 is connected-to the front ofthe receiver. A magazinetube 3 is mounted below the barrel and is adaptedto accommodate a plurality of cartridges 4 and 5 as shown in FIGURE 2. A magazine follower 6 and magazine spring 7 urge the cartridgesrearwardly toward the receiver. A forearm 8 isshown slidably mounted on the magazine. In semi-automatic and automatic firearms, the.
forearm is fixed to the magazine tube and .a piston is arranged in the front of the magazine tube to automativ I cally perform the function of the manually operated forc arm. Connected to the forearm 8 and reciprocable there with is a pair of slide arms 9 and 10. Slide arms Q and It are provided with cams 11 and 12 respectively. The f function of cams '11 and .12 will be explained in detail below.
Mounted in the receiver 1 is a pair of cutoff supports into the. receiver as clearly shown'inFIGURES' ZandiS.
to feed the second cartridgeinto.
FIGURE 2 is a sectional view taken along line I 3 19 and 20 respectively, which ride on the upper surfaces 21 and 22 respectively, of the cutoff supports. (Note FIGURE 5.)
FIGURE 2 shows the firearm with cartridges 4 and 5 positioned in the magazine tube 2. The cutoffs 15 and 16 are shown in their normal positions with cutoff 15 spring biased inwardly into engagement with the rim of cartridge 4, and cutoff 16 normally spring biased outwardly away from engagement with the cartridge. Note that cutoff 15 is mounted slightly rearward of cutoff 16 and that earn 11 on slide arm 9 is located forward of cam 12 on slide arm 11 Rearward movement of the slide arms 9 and 11? brings cam 12 into engagement with the cam follower 32 on cutoff 16. Cutoff 16 is cammed inwardly as shown in FIGURE 3 so that the cutoff engages behind the rim of cartridge 4 and is held in this position by the cam 12. Further rearward movement of the slide arms causes cam 11 on the slide arm 9 to engage the cam follower 31 on cutoff 15. Cutoff 15 is cammed outwardly as shown in FIGURE 4 thereby releasing cartridge 4 which is free to move into the receiver and onto carrier 23. As cartridge 4 moves into the receiver; cartridge 5 is moved rearwardly by magazine spring 7 and follower 6. The rim of cartridge 5 engages cutoff 16 which is positively held inwardly by cam 12. The slide arms are reciprocated rearwardly to the end of their stroke and then brought forward. As the slide arms are brought forward; cam 11 disengages cutoff 15, and cutoff 15 assumes its normal inwardly biased position shown in FIGURE 2. Further forward movement of the slide arms allows cam 12 to disengage cutoff 16 and cutofl 16 assumes its normal inwardly biased position thereby releasing cartridge 5. Cartridge 5 moves rearwardly slightly from the position shown in FIGURE 4 to a position as shown in FIGURE 2 where the rim of the cartridge engages cutoff 15. To feed cartridge 5 and subsequent cartridges into the receiver, the operation described above is repeated.
It is apparent from the above description that while cartridge 5 is moving the greatest distance in the magazine tube 3 under the greatest force; cutoff 16 is positively held in its path by the cam 12 on slide arm 11). This arrangement eliminates the possibility of cutoff 16 being merely biased outwardly by the impact force of the cartridge, thereby jamming the gun action.
This invention has been described in detail in connection with the preferred embodiment of the invention illustrated in the drawings. Variations in design and structural modifications are also contemplated which will be within the spirit and scope of the appended claims.
