Aug. 10, 1965 w. M. LARGEN SAFETY FOR GUNS Filed June 17, 1963 IN VENTOR.

William M. Largen I 3 g? il I United States Patent 3,199,249 SAFETY FUR GUNS William M. Largen, 1938 Avon Road, Roanoke, Va. Filed June 17, 1963, Ser. No. 288,326 6 Claims. (Cl. 4270) The present invention generally relates to a novel and improved safety for guns and more particularly to such a safety incorporated into firearms normally fired with the butt end of the stock resting against the forward surface of the shoulder. The safety of the present invention is automatically operated so that it is rendered effective, whenever the firearm or gun is removed from the shoulder-engaging firing position thereby rendering the firing mechanism inoperative whenever the gun is not in the firing position against the shoulder. As soon as the gun is placed in proper firing position, that is, with the butt end of the stock engaging the shoulder, the safety device of the present invention will be rendered inoperative and the firing mechanism of the gun will be rendered effective so that the gun may be fired in the usual manner.

While shoulder fired weapons such as shotguns, rifles and the like are normally provided with safety devices which prevent operation of the trigger when the safety is in its operative position, such devices require that the person carrying or using the gun manually move the safety to its operative position when the gun is not being fired and manually move the safety to its inoperative position when the gun is ready to be fired. Since this requires the person using the gun to manually manipulate the safety, it quite often occurs that the safety is not moved to an operative position when the gun is not being fired due to the user of the gun inadvertently forgetting to actuate the safety to its operative position or perhaps feeling that it is not necessary to move the safety to an operative position since the gun will be again used in the relatively near future. Failure to move the normally provided safety to an operative position results in frequent accidental discharge of guns with the consequent danger to persons in the near vicinity.

Accordingly, one of the primary objects of the present invention is to provide a safety device which will automatically become operative when the gun is removed from its shoulder firing position thereby preventing the trigger mechanism from being moved rearwardly when the gun is not disposed against the shoulder of the person shooting the gun. Conversely, as soon as the gun is placed in proper position with the butt end of the stock against the shoulder, the safety device is automatically rendered inoperative thereby enabling the trigger mechanism to be actuated in the conventional manner. Thus, regardless of what the conditions are or when the gun is next expected to be fired, as soon as the gun is removed from its firing position away from the shoulder, the safety of the present invention is automatically rendered effective for preventing the gun from being fired by accidentally moving the trigger mechanism.

Another object of the present invention is to provide a safety device including structural features which enable it to be securely locked in operative position when the gun is not in its area of use, for example, when transporting the gun in an automobile, placing the gun in a storage area or the like thereby eliminating any possibility of the safety mechanism beingrendered ineffective by the butt end of the gun coming into engagement with a supof the present invention will remain in an operative position.

Yet another important object of the present invention is to provide a safety for guns which is simple in construction, easy to install in existing guns with very little modification thereof, effective for its purposes and relatively inexpensive to manufacture while still being foolproof and long lasting.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a side elevational View of a portion of the gun with areas thereof broken away illustrating the orientation of the safety of the present invention;

FIGURE 2 is an enlarged sectional view of the rotatable safety member and its relationship to the trigger and the mechanism for operating the safety member;

FIGURE 3 is a detailed sectional view taken substantially upon a plane passing along section line 33 of FIGURE 2 illustrating further structural details of the rotatable safety member and its relationship to the trigger;

FIGURE 4 is a perspective view of the rotatable safety member;

FlGURE 5 is a detailed sectional view illustrating the structure of the actuating member and its relationship to the stock of the gun; and

FIGURE 6 is a plan view of the construction of FIG- URE 5.

Referring now specifically to the drawings, the numeral it generally designates a gun of any suitable character such as a conventional shotgun having a pump action or the like. The details of the gun are not illustrated except for the stock 12, the trigger guard 14, the trigger to, and

a receiver or breech 18 which receives the firing mechanisrn such as the firing pin, scar and the like. As is well known, the trigger mechanism including the guard 14 will drop out of the receiver or breech 18 when two transverse pins 24! are removed and the stock 12 is detached from the receiver 18 by virtue of removing the conventional elongated securing srew (not shown).

The trigger 16 is pivotally supported by a transverse pin 22 and includes a projection 24 on the rear surface thereof for reception in .a socket 26 formed in the periphery of a cylindrical safety member 28. The safety member 28 is also provided with a notch 39 in the opposite surface thereof from the socket 26 and an abutment area 32 is formed between the socket 26 and the notch Bil. When the safety member 23 is in operative position, the abutment surface 32 is in alignment with the projection 24 on the trigger 16 thereby preventing rearward movement of the trigger 16 about pivot pin 12. However, when the safety member 23 is rotated to a position so that the abutment 32 is below the projection 24, the socket 26 will be aligned with the projection 24 thereby receiving the projection 24 when the trigger 16 is pulled rearwardly thereby enabling the trigger 15 to be pivoted rearwardly about pivot pin 22. FIGURE 2 of the drawings illustrates the abutment 32 engaged with the projection 24 and by rotating the safety member 28 in a clockwise direction as illustrated in vFiGURE 2, the safety member may be moved to an inoperative position since the projection24 would then pass above the abutment 32 and be received within the socket 26 thus enabling the firing mechanism to be operated in the conventional manner.

The safety member 23 is retained in a transversely extending aperture 34 which conventionally receives the manually operated safety for such a gun by virtue of a setscrew 36 having a reduced axial extension 38 on'the inner end thereof received in the notch 36 which will preclude axial movement of the safety member 28 but enable limited rotational movement thereof between th operative and inoperative positions as defined by the axial extension or pin 38 engaging the ends of the bottom of the notch 30. The peripheral surface of the safety member 28 in the area opposite from the socket 26 and the notch Stlis provided with a plurality of longitudinal gear teeth 40 in meshing engagement with an elongated rack gear 42 slidable in a passageway 44 formed in the upper rear end portion of the trigger guard and trigger carrier assembly 46. The upper edge surface of the rack gear 42 is provided with a longitudinal recess 48 receiving a setscrew 50 for guiding andlimiting the movement of the rack gear 42 in relation to the safety 28. A lock setscrew 52 is provided for retaining the setscrew G in position.

The end portion of the rack gear 42 remote from the rotatable safety 28 is somewhat enlarged as at 54 and receives a compression coil spring 56 there around which engages the rear surface of the trigger carrier 46. The other end of the spring 56 engages a transverse pin 58 which connects the larger portion 54 of the rack gear 42 with an elongated operating rod 60 received in the hollow interior 62 of the stock 12. The hollow interior 62 is conventional and it is through this hollow interior that the stock securing screw is also accessible. The rear or butt end of the stock 12 is provided with a removable butt plate 64 held in place by suitable and conventional screwthreaded fasteners (not shown). The outer surface of the butt plate 64 is concave as indicated by numeral 66 and this also is a conventional structural orientation for the butt plate since it fits to the curvature of the front surface of the shoulder for more effectively enabling the gun to be properly held when being fired.

The but-t plate 64 is provided with a centrally disposed aperture 68 therein for slidably receiving a safety actuating member 70 in the form of a plate of generally rectangular cross-sectional configuration which may have a rounded outer end portion 72 for engagement with the shoulder. The top of the opening 68 is provided with a guide plate 74 having an upwardly inclined inner end portion 76 for sli-dingly engaging a safety lockout pin 78 when it is not functioning as a lockout pin. The plate 70 is provided with a socket 80 having :a small compression spring 32 therein which slidably receives the lockout pin 78. A transverse pin 84 extends through the plate 70 and through a longitudinal slot 86 in the lockout pin 78 for limiting the reciprocation thereof. While the pin 78 is slidably received in the socket 80, the close fitting relationship thereof is sufliciently loose to enable free sliding movement of the pin 78 in relation to the actuating member or plate 70. The outer end of the guide plate 74 is provided with a notch 88 which receives the lockout pin 7 8 when it is in operative position as illustrated in FIGURE 5. In this position, the actuating member 7t) cannot be pushed inwardly. However, in this position, the actuating plate 70 has been pulled outwardly slightly beyond its normal operating position. This is accomplished by grasping the side edges of the plate 70 and pulling it outwardly thus enabling the lockout pin 78 to be projected outwardly of the guide plate 74 and engaged in the notch 88 as illustrated in FIGURES S and 6.

The inner end of the actuating plate 70 is connected to an upturned end portion 90 on the end of the operating rod 60 by virtue of a U-shaped saddle 92 having a bight portion 94 pivotally engaged with the circular upstanding end portion 90. The bight portion 94 is provided with a plurality of notches 96 and the upstanding end portion 90 of the operating rod 60 is provided with a plurality of notches or transversely flattened areas 98 in the surface thereof in opposition to the inner end of the actuating member 70. A pair of coil compression springs 100 are engaged with the notches 73 respectively and extend into a pair of sockets 102 formed in the inner end of the actuating member 79 thus resiliently biasing the upstanding member 91} into engagement with the bight portion 94 of the U-sh-aped saddle 92. This retains the actuating member 79 in alignment With the rod tl and also enables rearward movement of the rod 60 in relation to the actuating member or relative resilient movement of the actuating member 70 in relation to the rod 69 thereby eliminating any possibility of the actuating member 79 causing discomfort during firing of the gun due to recoil of the gun against the shoulder.

The saddle 92 is secured to the actuating member by transverse pins or fasteners 104 and the side walls of the saddle 92 are provided with centrally disposed tunnel-like projections 106 each of which receives a coil compression spring 108 having one end engaging the inner end of the tunnel 106 and the other end engaging the butt plate 64 on opposite sides of the aperture 68 thereby enabling outward movement of the actuating member sufiicient to enable the lockout pin 78 to efiectively engage the notch 38. It is pointed out that the pin 58 which connects the rack gear with the operating rod 60 not only is a pivot pin but may provide a limited amount of lost motion to enable the actuating member 70 to move outwardly slightly and also to enable some initial inward movement of the actuating member 74) before the rack gear 42 and safety 28 are actuated or moved to an inoperative position.

When the lockout pin 73 is in the position of PI- URE 5, the abutment 32 is so positioned that the projection 24 will engage it thus assuring that regardless of the pressure exerted on the actuating plate 7 0, the trigger 16 cannot be actuated. During normal use of the gun such as when hunting or the like, the lockout pin 7 3 is pushed inwardly by engaging the thumbnail or fingernail therewith so that it assumes the normal position riding against the inner surface of the guide plate '74 with the springs 108 serving to retain this normal position. In this normal position, the spring 56 will return the safety 28 to its operative position as illustrated in FIGURE 2 but at any time the butt plate 64 is engaged with the shoulder, the actuating member 70 will be forced inwardly thereby rotating the safety member 28 so that the pocket 26 will receive the projection 24 on the trigger 16 thereby enabling actuation of the trigger. Due to the concave surface of the butt plate 64, the actuating member 76 will not be actuated when the gun is engaged with a fiat surface or even with the surface of the ground under normal conditions thereby rendering the safety device completely automatic in operation except when the gun is not to be used for awhile at which time the actuating member 7l may be pulled outwardly slightly so that the lockout pin 78 will register with the notch 88 as illustrated in FIG- URE 5.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
