SAFETY GUN TRIGGER Filed March 26, 1957 Z4 1 2g 5 L 6 INVENTOR 1. MEA f). A/mmsm 17/5 ATTORNEY This invention relates to a safety gun triggenand has for one of its objects the production of a simple and States atent eflicient means for positively locking the trigger of a gun against movement, and thereby preventing the accidental discharge of the gun, the parts of the device being easy to assemble.

A further object of this invention is the production of a simple and efiicient means for limiting the forward movement of the pull or push rod, so as to prevent the safety lock from wedging too tight.

Another object of the invention is the production of a simple and efficient latching means for the pull or push rod which will insure of instantaneous and positive release of the latching means and engagement with the pull or push rod when the push buttons are actuated, these push buttons being relatively long to facilitate gripping thereof by the hand of an operator particularly while wearing mittens and the like.

Other objects and advantages of the present invention viill appear throughout the following specification and am.

This application is an improvement on my Patent No. 2,380,140, issued July 10, 1945, relating to Safety Gun Trigger.

In the drawing:

Figure l is a fragmentary top plan view of a portion of a gun, showing the safety means located thereon;

Figure 2 is a horizontal longitudinal sectional view showing the parts in a locked position;

Figure 3 is a view similar to Figure 2, showing the parts in a released position;

Figure 4 is an irregular transverse sectional view taken on line 44 of Figure 2;

Figure 5 is an end elevational view of the trigger lock;

Figure 6 is an enlarged side elevational view of the trigger lock, a portion of the trigger also being shown;

Figure 7 is a detail perspective View of the latching dog or pawl, for locking and unlocking the pull or push rod;

Figure 8 is a fragmentary side elevational view of the inner end of the push or pull rod;

Figure 9 is a perspective view of one of the operating push or pull buttons.

The present invention constitutes an improvement over my previous Patent Number 2,380,140, issued July 10, 1945, and relating to a Safety Gun Trigger.

By referring to the drawing, it will be seen that 10 designates the stock of the gun, which carries the conventional barrel 11. The stock 10 of the gun is provided near its forward end with a pocket 12, in which is mounted a box 13. A button-receiving socket 14 is formed in one side of the stock 10 and communicates with the pocket 12. A button-receiving socket 15 is formed in the opposite side of the stock 10, and also communicates with the pocket 12. The socket 14 is in offset alignment with the socket 15. An elongated push-button 16 is mounted within the socket 14 and an elongated pushbutton 17 is mounted in the socket 15. These

pushbuttons

16 and 17 are elongated to facilitate pping thereof by the hand of an operator, particularly while wearing mittens and the like. A plunger rod 18 is carried by the push-button 16 and supports a pivot link 19. A spring 20 is interposed between the push-button 16 and the box 13 to normally urge the button 16 outwardly. This button 16 is preferably provided with a suitable flange 21 to limit the outward movement of the button 16. A similar spring 22 is carried by the button 17 and this button 17 is constructed similarly to the button 16.

The push-button 17 is provided with a plunger rod 23, and the plunger rod 23 extends into the box 13 for engaging and locking the pull or push rod 24 in a safety position in a manner described in the following. As is shown in Figures 2 and 3, the plunger rod 18 extends into the box 13 in an opposite direction to the plunger rod 23 and transversely of the box 13. When operated, the plunger rod 18 shifts the push rod 24 longitudinally to release the plate 32 from a locking position relative to the trigger 39-see Figure 6. t

The pull rod 24 extends longitudinally of the stock 10, and carries an expansion spring 25 at its forward end, the spring 25 being located in the socket 26, which extends longitudinally of the forward end of the stock 10.

The spring 25 is adapted to normally pull the pull rod 24 forwardly and this forward pull is limited by means of the stop 27 which abuts against the box 13, as is shown in Figure 2. The link 19 which is pivotally connected to the rod 18 is also pivotally connected to the pull or push rod 24 and is inclined rearwardly and away from the push-button 16, as is shown in Figures 2 and 3. The rod 24 is provided with a transversely extending toothreceiving notch 28 in spaced relation to the link 19, and this notch 28 is adapted to receive the toothed end 29 of the dog or pawl 30. The dog or pawl 30 is pivotally mounted upon the transversely moving plunger rod 23, is bodily movable away from said pull or push rod 24, and is provided with a rearwardly extending fulcrum finger 31, which extends into a suitable aperture formed in the stationary rear end of the box 13 constituting an abutment for said finger 31. The notch 28 is adapted to receive the toothed end 29 of the dog or pawl 30 for the purpose of holding or locking the pull or push rod 24 in a set position. The dog or pawl 30 is moved out of engagement with the notch 28 by pushing inwardly on the button 17 to permit longitudinal movement of the pull or push rod 24 when the button 16 is operated. As the dog or pawl is bodily moved away from the pull or push rod 24 it is simultaneously swung upon its pivot to swing the toothed end 29 out of the notch 28.

The rod 24 is provided with a knob 33 at its rear end, in front of which knob 33 is fitted a hook 34 of the trigger releasing and engaging slide plate 32. The rod 24 is provided with a shank 35 near the knob 33 for the purpose of receiving the hook 34. This hook 34 is carried by the forward end of the plate 32 and this plate 32 is provided with a pair of longitudinally extending slots 36 for receiving the retaining screws 37. The screws 37 are adapted to secure the plate 32 to the conventional bolt of the gun 38 shown in dotted lines in Figure 6. The plate 32 is provided at its rear end with a depending lip 40 which is adapted to engage the shoulder portion 41 of the trigger 39 and hold the trigger against movement until the lip 40 and the plate 32 are shifted to a desired position.

The operation of the device is as follows:

The parts are normally in the position shown in Figures 2 and 6. When it is desired to fire the gun, the left hand of the operator will engage the forward portion of the stock 10 adjacent the push-

buttons

16 and 17 with his right hand and trigger finger adjacent the trigger 39. The push-button 17 is then pushed inwardly, thereby re- Patented Feb. 3, 1959 tion shown. in Figure 6, where the depending. lip 40*.will

be moved. out oi engagement with the shoulder 410i the trigger 39. This movement will permit the trigger 39 to be swung for releasing the firing pin of the gun.

It should be understood that. the present. device may be applied to various types of firearms, and only those portions of the gun which are essential to all types have been illustrated, in view of the fact that the present invention relates to a means for locking the trigger against swinging movement until the. trigger is first mechanically releasedby the operation of the pushbuttons 16 and 1'7. As shown in Figure 6, the trigger 39 is pivoted, as at 42',

and it should be understood that, the bolt, the particular said pull rod for normally holding the pull rod in a safety position, a pull rod actuating member engaging the pull rod for shifting the pull rod when said locking member is released from said pull rod, the locking member and the actuating member being mounted adjacent said pull rod and extending at right angles to said pull rod, said locking and actuating members being located forwardly of said trigger and releasing plate, an elongated depressible push-button, mounted upon each side of said gun, one push-button being connected to said releasable locking member and the other push-button being connected to said pull rod actuating member, the elongated pushbuttons facilitating operation of the push-buttons while the operator is using hand coverings, such as mittens and the like, said pull rod having a notch, and said releasable locking member comprising a dog, a plunger rod, said dog being pivotally mounted upon said plunger to bodily move said dog away from said pull rod, said dog having a rearwardlyextending fulcrum finger, and an abutment for engaging said finger to simultaneously swing said dog out of said notch as said dog is bodily moved away from saidpull rod.
