SPECIFICATION forming part of Letters1Patent No. 489,191, dated January 3, 1898. Application filed May 27, 1892. Serial No. 434,554. (No model.)

To all whom it may concern: A arm, ashere shown, bearing upon a dog B, Be it known that I, ISAIAH S. HEATLY, of near the fulcrum point, and the upper arm Jersey City, county of Hudson, and State of of each spring engages with a link b which New Jersey, have invented a certain new and at the other end is pivoted to an arm'b of the 5 useful Improvement in Firearms, of which the hammers. following is a specification. I will now describe the meansfor cocking Thisinvention-relatestolocksanddisehargthe hammers.

It has a rearwardly m of the gun mechanism as will hereinafter apextending portion 0 on each side of which is pear. journaled 'an antifrictio'n roller 0' adapted to The invention consists in the construction bear upon the arms I) of the hammers. The and novel arrangement of parts as hereinafter upper end of the dog 0 has a lug c engaging set forth. in a hole, in the forward end of a link 0', r 5 In the accompanying drawings, Figure 1 is which, at the opposite end, is pivotally coua vertical longitudinal section of a gun mechnected toa slide plate 0 This slide plate is anism embodying my improvement.

The shaft of the pin- Referring by letter to the drawings A desion '0 extends upward through and has its v 25 ignates a frame designed to be secured to a bearing in a hole inthe top plate a and a gun stock in the usual manner, and consistcocking lever C is secured bya pin to the uping essentially of the side plates a, the top per end of the pinion shaft. It will be obplate a and the bottom plate a A vertical served that a'segment only of the pinion 0 wall a of the frameA forms the breech plate is used to operate the plate 0 but I prefer to 30 for the barrels A. This breech plate a. is provide the pinion with teeth throughout its 4 provided with holes a, through which the circumference, so that should a tooth be acciends of the central fire hammers B passto exdentallybroken the pinion may be shifted to plode the charge. At its lower portion the bring an operative set of teeth into position frame A is provided with a forward extension by merely removing the lever C or shifting 5 A to which the barrels are hinged as hereit rotarily in the pinion shaft. Of course in inafter described. Each hammer B is pivdoing this, it will be necessary to remove the oted on a pin or rod b extending from, one holding pin and drill a new hole through the side wall to the other of the boxing A. As shaft for its passage. shown, these hammers at their lower ends Theoperation ot'cocking the hammers may 0 have tubular blocks 11' through which the pin be described as follows:' The normal position or rod 1) passes,-and the inner or adjacent ends of the cooking lever C is in line with the lonof the blocks are provided with short arms gitudinal center of the gun. To cook the ham- 1) extending at substantially right angles mers the leverC is moved laterally, as shown to the blocks. Each block b is provided at in Fig. 3, to rotate the pinion C which slides 5 5 one side with a notch b into which the end the plate 0 rearward to the position shown of a pivoted sear 13' engages to hold the hamin Fig. 2. This movement of the plate (3 opmer in a cooked position. The sears B have crates, through the link C, to rock the cooka pivotal connection, as at b, with the frame ing dog 0, and turn the hammers on their a A, and the longer arm of each sear engages pivots until the ends of the scars B'catch into too 50 with a pivoted triggerB Springs B of the the notches Z1 of the hammers. The cooking usual construction, have the end of the lower of the hammers compresses the springs B so that they, will operate to throw the hammers forward to dischargothc cartridge. The parts as so far described as to the cocking of the hammers are in the position shown in Fig. :3; The lever 0' is now returned to its normal position and will return the parts t, C, ,to the position shown in-l ig. 1, leaving the hasntners'cocked. The hammers cannot" now be released, byzpulling the triggers B because the operation of the parts as described to cock the hammers, also sets a safety mechanism, which I will now describe.

I) is a vertically movable safety latch consisting of a plate cur.ved ldngitudiually and secured to a longittulinally curved lug (7, extending upward from the bottom plate a of l he frame A, by means of a screw d passing" .through a slot (1 in the latch, the lower end of the latch rests upon rearward projections d of the triggers, and is held thereon and moved in one direction by means of a spring plate 1) engaging at one end with an antifriction roller (Z journalell in an opening in the latch and secured at the other end to a slide plate D r The plate D is adapted to slide upon the under surface-of the plate a in line with the plate C A stud ,(1 extends upward from the plate D through a slot (1" in the top plate a and is provided with athumb piece D The plate D has a hole (I in it through which the upper end of the latch D extends.

The operation of the safety mechanism is as follows: When the plate (3 is moved rearward as before described, it moves the plate lT rearward and forces theutmaer end of the la-tchD against the under-surface of the plate u with the lower end upon the extensions (1- of the triggers as shown in Fig. :2. The plate C" may be now returned to its normal position, leaving the safety latch at safety. While the safety latch is in this positionacartridge rannot be discharged because a trigger cannot be operated to release a hammer. To set the latch in position so thateither one or both of the triggers may be operated the plate D is pushed forward Dymeaus of pressure on the thumb piece D This will leave a space in the slot (1 rearward of the lug (i coincident with the hole (F in the plate D and into which the upper end of the latch D may be forced when a trigger is pulled, as as shown in Fig, 1. Of course the forward movement of the plate D imparts a slight lo'ngitudinal movement to the latch and brings its upper end in line with the slot (1.

The manipulation of the parts to cook the ham mcrs as described also serves to release the barrels A so that they may be tilted in the usual manner to extract or insert cartridges, as I will now describe. A lug E extends downward from the barrels A and is provided in its front face with a semi circular bearing notch e adapted to oscillate upon a bearing pin c ext-ended between the cheek pieces e of the extension This construction allows the barrels to be wholly removed from the stock in. the usual manner. A lug E extends downward from the barrels in the rear of the bearing lug E and the ex- -tcnsion A is provided with a vertical opening e into which this lug E projects when the barrels are locked. is a locking bolt movable in guide ways in the upper portion of the extension A and a link (connects the rear end of this belt with the dog C as shown. The bolt E is provided with an opening e through which the lug B may move. The lug E is provided with a notch e into which the end of the-bolt E may slide and the lug E is provided with a notch 6- into which the end wall a of the opening 6 may slide to lock the barrels in the position shown in Fig. 1. The operation of thehammercockingmechanisnnasheretofore described .draws the bolt 1* out of the notches e c so that the barrels may be tilted as, shown in Fig. 2. A spring E secured at one end to the frame A and bearing at the otherend upon the end of the bolt E serves to push said bolt forward as the dog 0 resumes its normal position.

I will now describe the cartridge extracting mechanism. F designates the extractor the outer end of which is of the usual construction adapted to engage the rim of a shell. A steady pin f is movable in a longitudinal hole f in the center piece of the barrels and a slide piece f is movable in an opening f in the lower part thereof. When the barrels are tilted to extract a shell or shells, a rock lever F serves to push the extractor outward. This lever is pivoted between cheek pieces f of the removable stock piece F and has its upper end projected through an outward opening slot f into the openingf and impinging against the end of the slide piece f Thelower end of the lever F is cam shaped or rounded and bears or operates against the upper inclined surface of ablockf extended from one side of the bearing e. By this construction when the barrels are tilted the cam end of the lever F bearingagaiust the block f will rack said lever and cause it to push the extractor outward. The extractor is pushed inward when the barrels are thrown down by contactin g with the wall a.

In breaking or tilting the barrels the sudden shock at; the end of the movement sometimes breaks the joint. To obviate this I employ a fulcrumed stop G. This stop is fulcrumed between its ends to the lug E as shown and has its upper end projected into a slot g in the slide piece f. The lowerend is provided with a hook g to engage the forward end wall of the slot e" in the bolt E \Vhcn the barrels are tilted one end wall of the slot g will engage the stop and rock it on its pivot so that the hook y will engage the bolt E as shown in Fig. 2.

I have shown and described my improvement in connection with a double barrel fire arm, but I do not wish to be limited thereto, as, obviously, it can be used with a single barrel.

' Having described my invention what I claim, is:

- 1. The combination, with a hammer, and the operating spring, of the cooking dog, a

. sliding plate having rack teeth, a link connection between said plate and cooking dog,

a cooking lever and a gear operated by said leverand engaging the rack teeth of theplate, substantially as specified.

2. The combination, with the hammers, the

operating mechanism therefor, and the cockit ing mechanism, of safety mechanism consisting of the curved plate having a slot, the lug,

' the screw passing through the slot and securing the plate to the lug, and means whereby a the safety mechanism may be set by the operation of cooking the hammers, substantially I as specified.

' 3. The combination with the frame having the forward extension, and the barrels pivoted thereto, the locking bolt and the stop carried by the barrel and constructed to engage with the locking bolt when the barrels are in atilted position, substantially as specified.

4.. The combination with the frame having 'the forward projection, of the barrels pivoted thereto, the movable stock piece, the extractor and the rock lever having a cam. shaped end to engage, a block on the forward proj cation and engaging at its upper end with the extractor, the locking bolt and the'stop pivoted to a lug on the barrels and movable by the extractor to engage with the loclxingv bolt when the barrels are tilted, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
