FIREARM Filed July 19, 1932 2 Sheets-Sheet 2 MATTORNEY Patented Feb. 21, 1933 ars OTTO WILK, OF NEWARK, NEW JERSEY FIREARM Application filed July 19,

This invention relates to fire-arms, of the types known as single or double barrelled, shoulder fired, breech loading rifles, shotguns, or combinations thereof, and more particularly to the looks, or firing mechanism with which the are equipped.

One of the jects of this invention is to provide a firing mechanism in which is combined a safety catch that positively prevents a discharge of the fire-arm from occurring when the device is in operative position, quite irrespective of violent handling, shocks or jars that may be imparted to it, or other misadventures, until the safety catch has been withdrawn.

A further feature is in the provision of a gun lock combined with a safety device, that is applicable to any type of shoulder fire-arm, or shot-gun and rifle combination, that in nowise interferes with its ordinary use or impedes the instant action desirable in the use of the arm.

These and other highly important purposes will appear in the followlng description and are shown in the accompanymg drawings, constituting a material part of this disclosure, and in which Figure 1 is a partial top plan view of a gun lock made in accordance with the invention.

Figure 2 is a side elevational view of the same, the firing mechanisms being shown as being locked or inoperative.

barrel as extended ready for firing, the safety catch being moved into an inoperative position.

Figure 9 is a similar but partial view of the same parts in locked or operative position.

Figure 10. is a grouped perspectiveview of certain elements of the safety locking device in detail. 7

As shown in the drawings the invention comprises a hollow breech block, generally designated by the numeral 15, having at the rear the usual shoulder piece or butt, not shown, and at the lower front portions forwardly reaching side extensions 16 between which the barrel or barrels 17 are pivotally secured.

Fixed to the under side of the block is a guard 18 for a trigger 19 the main narrow element 20 of which passes through a slot in the breech block and rotates on a pivot 21 set therein.

'Extending integrally from the lower side of the breech block 15 into the chamber therein, are lugs 2223 carrying a fixed pivot pin 24 in their forward portions, and

. mounted thereon is a striker 25 adapted to contact with the head of a spring pressed firing pin 26 extending through the front wall of the breech block to make forcible 8 in the detent and the other engaged in a slot 29 in the striker 25.

Also pivoted on the pin 24: is a detent 30 having a laterally extending lug 31 engageable in a recess 32 in the striker whereby it may be prevented from action.

The lower end of the striker 25 is curved and formed to present a tooth 33 engageable by the forward end of a lever 34 pivoted on a pin 35 set in the lugs 2223 rearwardly of the pivot 24.

The rear portion of the lever 3 1 is held in contact with the upper face of the trigger 20 by a flat spring 36 which also retains the point in engagement with the striker tooth 33 until the trigger has been drawn upwardly by an operator.

Attached by a pivot 37 to the detent 30 is a rear reaching link 38 connected at its opposite end by a pivot 39 to a tumbler lever 40, pivoted at 41 to tilt within the breechblock chamber.

The upper end of the lever 40 is curved to present a semicircular head engaged be tween a pair of lugs 42-43 extending downwardly through a slot 44 in the upper wall of the breech block, these lugs being in tegral with a slide 45 movable over the slot and drawn rearwardly by a tension spring 46.

The forward lug 42 is drilled to slidably receive the stem of a plunger 47 having an enlarged head, spring pressed upwardly through the counterbored opening in a mound raised from the slide to be accessible by the fingers of an operator.

The inner end of the plunger 47 is secured by a screw stud 48, operating in a slot 49 in the lug, to catch lever 50, pivoted at 51 to the lug 43 and provided at its forward portion with a projection 52 engageable in a corresponding opening 53 in the breech block chamber wall. 7

At the forward extremity of the catch lever 50 is a ledge 54 adapted to be engaged by the rear end of escapement lever 55 pivoted at 56 to lugs reaching in from the chamber wall, the bevelled upturned for-- ward end 57 of the lever being normally depressed by a compression springo58.

The bevelled end 57 is brought into contact with the correspondingly bevelled upper edge 58 of the striker 25, as seen in Figs. 7, 8 and 9, when the striker is in a retracted position.

At the lower end of the striker is a seat 59 to be contacted by rear end of a lever 60, pivoted at 61 to the breech blockextension 16, the lever terminating at the front in a hook 62 engaged by the barrel when turned down, as in extracting a shell or reloading, the rear portion of the lever being held in a normally raised position by a flat spring 63.

In breaking down the barrel, the usual type of lever 64 is mounted on top of the breech block, see Fig. 1, and 1 operatively connected with a breech block pin '65 to retain the barrel in the customary position.

If a double barrelled gun, or combination of shot-gun and rifle are used, as indicated in Fig. 1, each will have its individual firing mechanism but as they are essentially alike in construction, one only. has been described.

In operation, let it be assumedthat the gun is loaded and the barrel extended in the ordinary manner, the striker 25 having been cooked by the lever 60 when the barrel was turned down to eject a spent shell. and reload, as indicated in Fig. 7.

The striker is moved an abnormal dismove the detent 30 rearwardly from the position shown in Fig. 7, to that seen in Fig. 8, this movement being aided by the spring 27 to the limit of its force and which then becomes lax and inoperative even if the trigger 18 be drawn.

This condition obtains and continues until the slide 45 has been moved'forward into the position shown in Fig. 9, where the spring 27 is compressed and ready to hurl the striker against the firing pin 26 when the trigger is pulled, causing the lever 34 to release its hold on the striker.

The safety device may also be set manually by depressing the plunger button 47 thereby releasing the safety catch 50 to be drawn back by the springs 46 and 47, and through the lever 40 and link 34 move the detent 30 rearward, relieving'the spring 27 of itscompression, thereby assuring complete safety from firing. f a

From the foregoing it will be understood that the safety catch is automatically applied upon reloading of the gun and no possibility of firing can take place until the safety slide has been shifted forwardly as explained. V

It will be apparent that the safety device can'be'manually applied and will remain in either of its adjusted positions until action is required. f

While certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangement, proportions? sizes and details thereof may be made without departing from the scope of the invention as defined in the appended claims.

Having thus d'escribed the invention, what is claimed as new and desired to secure by Letters Patent, is I 1'. In a breech loading gun the combination with a firing mechanism including a firing pin, a striker therefor and means actuated by the breeching of the gun to cock said striker, of a detent pivoted alongside said striker, a striker spring anchored in said detent, a lerer link connected to said tion with a firing mechanism including a firing pin, a striker therefor and means actuated by the breeching of the gun to cock said striker, of a detent pivoted alongside 5 said striker, a striker spring anchored in said detent, a lever link connected to said detent, a spring drawn slide engaging the free end of said lever, a catch to retain said slide when its spring is tensioned, means for releasing said catch, and means for restoring said catch in operative position.

3. In a breech loading gun the combination with a firing mechanism including a firing pin, a striker therefor and means actuated b the breeching of the gun to cook said stri er, of a detent pivoted alongside said striker and having means for engagement therewith operable in one direction, a Spring to actuate said striker, said spring being anchored in the detent, a lever linked to said detent, a second lever engaged on the free end of the linked lever, said second lever being slidably mounted, a spring to draw the lever slide in one direction, a retaining catch for the lever slide, and a third lever mounted to displace said catch upon contact with said striker.

In witness whereof I have signed my name to this specification. 3o OTTO WILK.
