SAFETY ACTUATOR FOR FIREARMS Gordon C. Bent, Jr., Green Bay, Wis.

Application November 17, 1952, Serial No. 320,963

1 Claim. (CI. 42-70) This invention relates to new and useful improvements in safety devices for portable shoulder firearms and the primary object of the present invention is to provide an actuator for the cross-bolt safety of a firearm, whereby the cross-bolt may be readily moved to its off position by the thumb of the users trigger hand while the users trigger finger is inside the trigger guard resting lightly on the trigger and the other three fingers in shooting position on the grip of the stock.

Another important object of the present invention is to provide a pivotal lever attachment for firearms having an angulated end terminating in a cam that will ride against the cross-bolt safety of a firearm as the lever is pivoted, to move the cross-bolt to its off position.

A further object of the present invention is to provide a safety device for firearms that includes parts that will replace the assembly pin and safety button of a firearm to permit a more convenient actuation of the safety than was heretofore possible and which safety device may be removed and replaced by the normal assembly pin and safety button when desired.

A still further aim of the present invention is to provide a device of the aforementioned character that is extremely small and compact in structure, efiicient, and durable in use, inexpensive to manufacture, and other- Wise well adapted for the purposes for which the same is intended.

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 l is a fragmentary perspective view of a firearm and showing the present invention mounted thereon;

Figure 2 is a bottom plan view of Figure 1;

Figure 3 is a view similar to Figure 2 but showing the lever depressing the safety to an off position;

Figure 4 is an enlarged front elevational view of the lever used in the present invention;

Figure 5 is an enlarged view, partly in elevation and partly in section showing the lever attaching pin; and

Figure 6 is an enlarged elevational view of a conventional trigger plate pin which is replaced by the pin of Figure 5 when the lever is attached to the firearm.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral 10 represents a firearm having a trigger guard 12 with a transverse cross-bolt safety accommodating aperture 14 that receives the novel cross-bolt safety of the firearm.

nited States Patent 0 2,711,043 Patented June 21, 1955 The trigger plate and its components (trigger, trigger guard, hammer, etc.) is fastened to the receiver 10 by factory installed front trigger plate pin 15 and rear trigger plate pin 16.

The present invention involves a novel cross-bolt safety 18 that is slipped in the aperture 14 to replace the normal cross-bolt safety of the firearm. One end 20 of the crossbolt or pin 18 is tapered, this end being the one that is pressed to move the cross-bolt to its off position.

A lever forming strip 21 is bent at one end portion to extend toward the trigger guard 12 and the strip 21 is formed with a countersunken aperture 22 adjacent its lower angulated end 24 that receives the head of fastener 16. The end 24 terminates in a bent rounded lip or cam 26 for riding against the tapered end 20 of pin 18. The upper end 28 of strip 21 fixedly supports an outwardly projecting conical lug 30 that may be engaged by a user's thumb.

In practical use of the present invention, the upper end of lever 21 is disposed rearwardly at the time the pin 18 is disposed with its tapered end 20 exposed as shown in Figure 2 and by full lines in Figure 1. A user having his trigger finger on the trigger of the firearm may push the upper end of the lever 21 forward with his thumb engaging lug 30, so that cam 26 rides against end 20 to move the pin 18 to its releasing or off position illustrated in Figure 3 and by dotted lines in Figure 1.

In order to permit the lever to be attached to the firearm, the rear normal trigger plate pin 16 is replaced by a pin 16a slightly larger than pin 16 and having a threaded recess 17 at one end accommodating a screw 19 that extends through the aperture 22. Pin 16a is slightly larger at one end 16b than pin 16 so that when the lever 21 is swung forwardly to ride against the beveled end of the cross-bolt, the stress applied to pin 16a will not cause pin 16a to be pulled through the receiver 10. The pin may be readily removed and replaced by the normal pin 16 if desired.

What is claimed as new is:

In a shoulder firearm including a horizontally reciprocable cross-bolt safety positioned in a transverse bore in the upper end of the trigger guard and having a tapered end normally projecting from the side of the trigger guard, an elongated strip forming a lever having a central portion pivotally secured to one side of the firearm above the safety, a lower angulated end on said strip extending under the firearm towards the trigger guard and terminating in a cam for selective engagement with the tapered end of the safety, and a projecting tapered lug on the upper end and outer surface of said strip for engagement by a thumb for manipulation of said lever and safety, said angulated end positioned adjacent the trigger whereby a trigger finger may contact said angulated end for determining the position of said lever and safety.
