in the usual gun, whenever the safety is in 5 the on position, it requires an appreciable period of time to move the same to the ofi" position for firing. Under these circumstances, it is quitecommon for hunters and other persons who find it necessary to fire their guns quickly 3 to leave the safety oil in order that the gun may be always ready to the. This is considered dangerous practice because the firearm maybe accidentally discharged.

' It is the purpose of the present invention to provide a safety mechanism that is capable of being set to a plurality of safety positions. In

other words, it is the purpose of the safety mechanism, in accordance with the present invention, to provide a. compound safety capable, in one a position, of being quickly released so that the gun may be quickly fired. In another position,

this safety is capable of being locked by an additional safety means.

In other words, a hunter having a gun equipped 5 with a safety mechanism, in accordance with the present invention, can keep the safety in the quickly releasable or intermediate on position when carrying the gun under conditions where a quick shot is expected. In the eventthat the gun was being carried over rough terrain or otherwise handled so that a very positive safety is the primary essential, the mechanism. according to the present invention, may be set to a double locked or on position.

One-cf the objects of the present invention,

therefore, is the provision of a'novel compound safety mechanism for a gun.

Another object of the present-invention is the Q provision or" a safety mechanism having two different locking actions.

Still another object of the present invention is the provision of a safety mechanism for firearms capable of being quickly released.

5' Other objects and advantages of the invention portion of the safety mechanism in the interor counterclockwise direction, serving to keep the 4 will be obvious from the detailed description which follows. ,6

Referring to the accompanying drawing:

Figure 1 is a side elevation partially in. section of a trigger and safety mechanism, in accordance with this invention, the safety mechanism being shown in the ofi or released position, and the trigger mechanism shown in the cocked position ready to fire.

Figure 2 is a side elevation partially in sectionshowing the safety mechanism in the on position. t

Figure 3 is a detail partly in section of a portion of the safety mechanism in the off or released po it Figure 4 is a detail, partly in section, of a portion of the safety mechanism in the "on position. a

Figure 5 is a detail, partly in section, of

mediate on position. I

Figure 6 is a perspective view of the safety pin.

Figure '7 is a perspective view of the safety lever.

Referring to Figure l of the drawing, 9 indicates a lever which is normally spring pressed in an upward direction. As is clearly understandable, this lever is merely indicative of a moving part of a firearm or striker release member. For the purposes of the present disclosure, it may be assumed that lever i, when moved in an upward direction,'releases the striker of a firearm in any suitable fashion, and when held in the position shown in Figure l prevents the firing of the gun.

Lever'l carries a lug 2 having a pawl engaging nose 3 which engages the hook t of the pawl 5. Pawl 5 is pivoted on a pivot 8 carried by a suitable portion of a firearm, as for example, the trigger guard 2d. Nose l carried by the pawl plunger 8 engages the pawl 5 in a notch Pawl plunger spring it, through the medium of the nose 5 and notch 9, urges the pawl in a backward pawl hook d in firm engagement with-the nose 3.

The depth of engagement of the pawl hook and nose is determined by the position of the adjusting lever it, pivoted at E2, on a suitable por-' tion of the firearm. Adjusting lever it carries 'a finger it, which bears against the pawl 5 limiting the counter-clockwise movement of the pawl and thus limiting the engagement of hook '6 and nose 3. The position of the adjusting lever is determined by a screw indicated at it. 1 5

Trigger 5 carried on pivot 6 has a dual engagement with the pawl 5. The trigger carries a plunger i6 (Figure'l) which is capable of sliding movement in the trigger. This plunger I8 is urged into pawl engaging position by a spring l6a. The action of this plunger positions the trigger so that the pawl is held between the plunger I8 and finger I! carried on the trigger. Trigger spring 1|8 acting-6n plunger i9 serves to retain the trigger in its forward position.

The safety mechanism of the firearm comprises a safety lever 20 carried on a pivot 6 having a bow 20a 0n the lower portion thereof and a cam lug 2| on its upper portion. The cam lug 2| is adapted to seat in a notch 22 in the lever lug 2. Slidably mounted in a hole 23 in the trigger guard 24 of the firearm is a safety pin 25. The safety pin comprises a knurled head 26 and a cut away portion indicated in general at 21. This cut-away portion comprises a fiat upper face 28 and a cam face 29 having a relieved portion 3|i and a rise 3|.

Plunger 32 urged into a downward or safety pin engaging position by spring 23 engages the fiat face 28 and serves to retain the safety pin either in on" or off" position.

The safety pin 25 is shown in Figures 1 and 3 in the off position. In this position, the safety lever bow 20a, is in its extreme forward position, bearing against cut-out portion 30 and the cam lug 2| is in rear, disengaged position.

In this position the trigger can be operated to fire the gun. A pull on the trigger l5 will move pawl 5 by means of plunger I6 to a forward position to disengage hook 4 and nose '3. In order to set the safety mechanism to on position and prevent firing of the gun, knurled head 26 is pushed in, thereby sliding relieved portion 30 from the position shown in Figure 5 to the position shown in Figure 4. Cam face 29 forces bow 20a rearwards about its pivot B, causing the upper portion of the safety lever carrying the cam lug 2| to move in a forward or in a clockwise direction. The cam lug 2| in moving into the forward position shown in Figure 2, forces the lug 2 in a downward "direction and seats in the notch 22. In this position, due to the positive engagement of the cam lug 2| and the notch 22, the gun cannot be fired since the lever I cannot move in an upward direction.

In this position, the safety is said to be on and in order to fire the gun, it is necessary not only to push the safety pin off but it is also necessary to move the safety lever bow 20a forward. If, however, it is desired. to leave the safety mechanism in what is termed the "intermediate on position, as shown particularly in Figure 5, it is only necessary to push the safety pin to the position shown in Figure 5, without moving the safety lever.

When the safety is in this position it is capable of being quickly released or moved to off. This "intermediate safe" position is, therefore, particularly adapted where a quick shot is desirable, as hereinbefore explained.

It may, therefore, be seen that the safety pin 25 functions as a primary locking safety means capable of assuming safe and ready to fire positions, and the safety lever 20 functions as a secondary quick releasing means. It may be further noted that the primary means or safety pin 25 is adapted to lock the secondary means or safety lever 20 against release when the safety pin is in the safe or on position. v
