SAFETY-LOCK FOR GUNS.

To all whom it may concern:

Be it known that I, GEORGE E. HEGKMAN, a citizen of the United States, residing at Gipaw, 'in the county of Hall, State of Texas, have invented certain new and useful Improvements in. Safety-Locks for Guns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to air guns and particularly in the provision of a safety lock for holding the trigger thereof against movement to release the spring pressed plunger until the lever arm by which the compression of said plunger is had is removed from the path of travel of said plunger when released.

To this end the invention consists in providing a spring pressed catch adapted to engage a lug on the trigger to hold said trigger against a rearward or releasing movement and in further providing on the handle portion of the lever which compresses the plunger means adapted to engage said latch to release the trigger When said lever has been moved entirely out of the path of travel of the spring pressed plunger when same is released.

In describing the invention in detail reference will be had to the accompanying drawings in which like characters of ref erence denote corresponding parts in the several views, and in which,

Figure 1 is a side elevation of a fragment of an air gun with the invention incorporated; a part of the casing which contains the trigger mechanism and a portion of the spring pressed plunger being broken away; Fig. 2, a view similar to Fig. 1, looking from the opposite side of the gun, one side of the casing being removed and the parts being shown in the position occupied at the termination of the cooking movement; Fig. 8, a section on the line 33 of Fig. 1 looking toward the rear of the gun; Fig. 4., a section on the line 4% of Fig. 2 looking toward the rear of the gun; Fig. 5, a detail perspective view of the safety latch, and, Fig. 6, a detail perspective view of the trigger.

Referring to the drawings, 1 indicates the stock of the gun having the customary formation, 2 the casing which contains the trigger mechanism, a portion of the spring Specification of Letters Patent.

pressed plunger and the safety lock and 3 the barrel of the gun; said casing 2 being suitably secured at opposite ends to the stock 1 and the barrel 3 respectively. The barrel 3 has a forward extension 4: attached thereto, the rear end of said extension having a perforated diaphragm 5 therein. lVithin the barrel extension 4 is suitably mounted a tube 6. This tube is provided with an opening near the rear end thereof as indicated at 7 and forms the firing tube of the gun. Above the firing tube is located a magazine tube 20 provided with an opening 21 communicating with the tube 6.

Below the barrel 3 is secured a cylinder 8 wherein is held a spring 9. Vithin the easing 2 is pivoted a trigger 10 the free end of which projects through a slot 11 in the casing and a spring 12 normally holds the trigger in engaging position. Slidable in the barrel 8 is a plunger 13 provided with a head 14 which closely fits the barrel and has a suitable packing 15 to provide an airtight engagement between the barrel and said head. The end of this plunger extends within the casing 2 and is provided with a slot 16 through which projects the upper end of the lever 24 and wherein is mounted a roller 17 which is adapted to be engaged by the rear face of the lever and serves as an anti-friction bearing. The plunger 13 is provided with a notch 18 to form a shoulder adapted for engagement with the sear 19 of the trigger and has a rearwardly extending end 22 which forms a guide to keep the plunger in proper alinement with the barrel 3. A compression spring 28 is mounted in the barrel 3 and has one end bearing against the head of the plunger and the other end thereof against a shoulder (not shown) formed in the casing 2. A lever 24: is pivoted to the casing and projects through the bottom thereof, said lever being formed with a handle portion 25 normally resting against the under side of the stock and a reduced end 26 which extends up in the slot of the plunger and bears against the roller mounted therein. This lever is further provided with a slot 26 wherein is pivoted a rod 27 having an enlarged end 28' which bears against the end of the spring 9. This rod 27 is so arranged that the spring 9 normally forces the handle portion of the le ver against the under side of the stock.

It will be noted that the operating lever and the plunger pivoted thereto are so arranged that when the operating lever is in the position for firing the pivot of the plunger lies below the pivot of the lever while in the charging the positions of these pivots are reversed. It will thus be obvious that when the handle of the operating lever is moved against the stock the spring 9 through the medium of the rod 27 will serve to hold the handle in that position.

Pivoted to one side of the casing 2 is a latch 29 and a spring 29 mounted above said latch on the side of the casing which constantly tends to force the free end of said latch downward. On the under face of said latch near the free end thereof is formed a notch 30 which is adapted to engage the transversely disposed lug 31 on the trigger to hold said trigger against rearward movement. In order to make the engagement between the latch and the trigger more positive a pivoted pawl 32 has its free end pressing in a notch 33 formed in the upper face of the latch and a spring 34 constantly tends to force said pawl and latch downwardly. Secured to a portion of the lever handle situated without the casing 2 is a contact finger 35 which is adapted to pass through a slot 36 in the bottom of the casing and bear against the under side of the latch 29 when the handle 25 is disposed against the stock 1. In all other positions of the handle 25 the contact finger 35 is without influence on the latch 29.

The operation of the safety lock just described will be obvious. When the parts of the gun are in the position they occupy at the termination of the cooking movement, as is illustrated in Fig. 2, it will be seen that if the trigger 10 were prematurely moved and the plunger 13 released it would result in the lever arm 24 being moved forward with great force and produce a corresponding movement in the handle 25 of said lever arm with possible injury resulting to the hand of the operator. By reason of the safety look just described, however, such a premature movement of the trigger would be impossible as the contact finger 35 would not be in engagement with the latch 29, and the latch would be pressed down into interlocking engagement with the lug 31 of the trigger through the medium of the spring 29. hen the handle 25, however, is moved into contact with the stock 1 the contact finger 35 will raise the latch 29 and release same from engagement with the trigger so that the latter may be pulled at the will of the operator.

While I have shown the particular form of safety look as applied to an air gun it will be obvious that same may be applied to any gun which utilizes a pivoted lever to effect the cocking thereof.

It will be noted that in order to remove the pawl 32 from the notch 33 to permit raising thereof by the contact finger 35 the latch 29 is provided with a recess 37 in one side thereof, while said contact finger 35 is provided with an upwardly extending offset portion 35 adapted to pass between the walls of said recess and engage and raise the pawl 32 prior to the engagement of latch 29 by the contact finger.

What is claimed is 1. The combination with a gun, of a firing mechanism, a lever for moving said firing mechanism to active position, a trigger for engaging and holding said mechanism in active position, a pivoted latch adapted to engage said trigger to hold same against movement to release said firing mechanism during the movements of said lever, a pawl engaging said latch to positively lock same against dis-engagement from the trigger, and a contact finger adapted to successively engage and move said pawl from engagement with the latch and said latch from engagement with the trigger as the lever is moved to normal position.

2. The combination with a gun, of a firing mechanism, a lever for moving said firing mechanism to active position and normally disposed against the stock of the gun, a trigger for engaging and holding said mechanism in active position, a pivoted latch adapted to engage said trigger to hold same against movement to release said firing mechanism when said lever has been actuated to move the firing mechanism to active position, said latch having a side face pro- 100 vided with a recess, a pawl disposed across said recess above said latch and engaging the latter to positively lock same against disengagement from the trigger and a con tact finger carried by the lever having a 105 reduced upper portion forming a shoulder intermediate the ends of said finger, said reduced portion being adapted to pass through the recess in the latch to engage and release the pawl from engagement with 110 the latch and said shoulder being adapted to subsequently engage and move the latch from engagement with the trigger as the lever is moved to normal position.

In testimony whereof, I affix my signa- 115 ture, in presence of two witnesses.

GEORGE E. HECKMAN.
