LOCK FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 594,863, dated December 7, 1897. Application filedJ'une 25, 1896. Serial No. 596,899. (No model.)

To all whom, if; may concern;

Be it known that I, OTTO P. ELTERICH, a citizen of the United States of America, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Looks for Firearms, of which the following is a specification.

Myinvention has reference to improvements in firearms, and especially to the locks of hammerless guns, it having for its objects, first,

to obtain simplicity of construction and durability, combined with absolute safety, and, secondly, to enable the gun to be cooked with safety in case the trigger-spring should break.

The nature of my invention will best be understood when described in connection with the accompanying drawings, in which- Figure 1 represents a longitudinal central section of a lock embodying my invention applied to a double-barrel hammerless shotgun. Fig. 2 is a similar view showing the barrels open and the construction of the springhammer slightly modified. Fig. 3 is a side elevation of the trigger-plate and parts thereto appertaining removed. Fig. 4 is a top View of the same. Fig. 5 is a cross-section on the line 5 5, Fig. 1, taken through the gunbarrels. Figs. 6, 7, and S are detail views. Fig. 9 is a detail view illustrating a modified form.

Similar letters and numerals of reference designate corresponding parts throughout the several views of the drawings.

In the present example I have illustrated a double-barrel gun, with its accompanying mechanism, but shall describe the mechanism as if adapted for a single-barrel gun, since the operative parts are merely duplicated.

Referring to the drawings, the letter A designates the frame of the gun, adapted to receive the trigger-plate B and its attached mechanism, said trigger-plate being secured to the frame by

bolts

1 and 2, as usual. The barrels O and the fore-end D are attached to the frame A in the manner usual in breakdown guns, the usual form of top lever E and an automatic safety device 8 being provided.

According to my present invention I combine the hammer and mainspring to form what I shall term the spring-hammer II, which is made substantially in V form, with one leg shorter than the other. It is fitted into a recess formed in, the side of the triggerplate B and is secured by a screw Z), passing through a horizontal extension of the shorter limb. At its upper end the longer limb is provided with a head 0, adapted to engage with the firing-pin d, or, as shown in Fig. 2, it may be formed also with a pin d, adapted to strike the cartridge. The spring-hammeris adapted to be engaged near its upper end by a pin 6, carried by the lifting-lever tumbler F, which is adapted to turn about a stud f, secured in upright lugs formed on the trigger-plate B. The lifting-lever tumbler is provided with a vertical arm g, carrying the pin 0 before mentioned, a horizontal arm h, adapted to be engaged by the tappet i on the lug G, attached to the gun-barrel, and a second horizontal arm j, provided with two notches adapted to be engaged by the sear m. The scar on is pivoted at Z to suitable lugs on the triggerplate B, and its rearwardly-projecting arm I is provided with a horizontal pin n, adapted to engage with a slot 0, formed in the web of the trigger '1. The trigger-web is also provided with a notch 23, into which extends the end of the trigger-spring q, the latter being secured by a screw 0", as usual.

I will now proceed to describe the operation of the parts, including those usually found in firearms of this description. The top lever E is first turned laterally, thereby drawing the bolt i from the recess t, formed in the lug c on the barrels O, thus permitting thebarrels to be turned down for the insertion of the cartridges. With the turning down of the barrels the tappet t' on the lug G engages with the arm h of the lifting-lever tumbler F and turns the same to the position shown in Fig. 2, thereby throwing the spring-hammer II backward. The scar m is then turned about its pintle by the action of the trigger-spring q, transmitted through the trigger, and its nose drops into the top notch 011 the lifting-le-.

ver tumbler. The barrels are then turned upwardly again. hen the trigger is pressed, the sear m is lifted and frees the lifting-lever tumbler, as usual, and the springhammer descends with its full force.

The lock can be cooked with the aid of the fore-end by the introduction of a second cocking-lever w, as shown in Fig. 9, which engages the arm h of the lifting-lever tumbler and operates in connection with the fore-end in the usual manner.

In View of the pin-and-slot connection between the scar and trigger I am also enabled to use the gun should the trigger-spring q break, it being simply necessary to turn the trigger forward while the gun is being cocked, thereby elevating the engaging end of the sear and throwing the nose of the same in position to engage the top notch in the liftinglever tumbler F. After the gun is cooked the sear will hold the lifting-lever tumbler with the greatest safety. It will also be noticed that the use of a special sear-spring is dispensed with, as the trigger-spring fulfils the functions of the former.

It is of course to be understood that the lock herein described can be applied to guns of other constructions and also to pistols.

What I claim as new is 1. A look for a firearm,comprisin g a springhaminer,alifting-tumbler operated byamovement of the barrel and having an upright arm engaging with the spring-hammer, and a scar engaging said tumbler,substantially as specified.

2. A lock for a firearm, comprising a springhammer, a lifting-tumbler having an upright arm engaging with the hammer and an arm having connection with the barrel, whereby the tumbler is operated by a-movement of the barrel, and a sear engaging said tumbler,

substantially as specified.

3. A lock for firearms, a trigger-plate provided with means for supporting the operative parts of the lock, said parts being composed of a lifting-tumbler having rear notches,

whereby the tumbler is operated by a movement of the barrel, and an upright arm, a scar adapted to engage in the notches, a springpressed trigger having a sliding connection with the sear, and a V-shaped spring-hammer engaged by the upright arm of the liftingtumbler, substantially as specified.

4. In a lock for firearms, a hammer and mainspring formed of one piece and affixed to a trigger-plate, alifting-tumbler operated from the barrel and having connection with the spring-hammer, a trigger having a slot, and a sear engaging the lifting-tumbler and having a pin extended into the slot in the trigger, substantially as specified.

5. In a lock for firearms, the combination of a trigger-plate, a spring-hammer made in one piece,a lifting-tumbler pivoted to the trigger-plate and provided with an arm engaging the spring-hammer and with a forwardly-extended arm, an operative connection between .the latter arm and the barrel and a sear engaging the lifting-tumbler, substantially as specified.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 11th day of June, 1896.
