ARTHUR J. STRONG, onBRoOKLYN, New YORK.

Application tiled March 25, 1893.

To @ZZ whom t may concern.-

Be it known that I, ARTHUR J. STRONG, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Firearms; and Ido hereby declare that the following is a full, clear, of the same, reference being had to the accompanying drawings, makinga part of this specification, in which- Figure l is a longitudinal sectional view taken in the line u, u, of Fig. 5. Fig. 2 is a like view taken in the line o, o, of Fig. 6. Fig. 3 is a like view taken in the line w, 10,0f Fig. '7, and showing the 'parts in a position dierent'i'rom that shown in Figs. l and 2. Fig. 4 is a longitudinal sectional View taken in the line of Fig. l, and in a plane at right angles to those of Figs. l, 2, and 3. Fig. 5 is a transverse sectional view taken in the line, y, y, of Fig. 8. Fig. 6 is a like view taken in the line, z, z, of Fig. 8. Fig. 7 is a rear end view of the barrel portion of the firearm, and Fig. 8 an inverted plan view of the same, with the barrel lug.

This invention relates to that class of tirebreech is opened by tilting the rear end of the barrel outward from the breech-receiver, and its object is to provide afirearm of this class which shall be simple in construction, capable of economical manufacture, strong and durable, and not liable to get out of order during the vicissitudes of use and operation.

The drawings represent the invention as embodied in a double-barreled shot gun, but it is, of course, eqitally applicable to rifles, &c., and as will be manifest from the description hereinafter presently given, certain of the combinations of parts included in said invention may be embodied in single bar- Figs. l and 2 show the arrangement of the parts as provided in connection with one of the barrels of a double barreled shot gun. It is of course to be understood that, unless hereinafter qualified, such arrangement of parts is duplicated within the same frame and stockv with due relation to the other barrel. A description, therefore, of such arrangement concerning one barrel applies equally to that concerning the other.

A, is the stock, B, the frame, and, C, one of SPECIFIATION forming part of Letters Patent No. 517,989, dated April 10, 1894.

the barrels. The barrels have pivotal connection with theframe in the usual or in any suitable manner as shown at, a. That part, Z), of the frame behind the pivotal point, a, including the recoil block, c, constitutes the breech-receiver, the recoil block, c, closing the breech of the barrel when the latter is depressed to its place upon the part, b, of the frame.

Fast at the under side of the barrel is abarrel lng, D, which is chambered 'on its under side as shown at, CZ. At the rear end of this chamber, d, is a pin, e, the position of which is shown in Figs. l and I3.

E, is a rocking dog which is pivoted as shown at,f, and the lower forwardly projecting part of which is notched or forkedv las shownl at, g. Said fork, g, is placed astride the pin, e, to engage therewith. n

F is the hammer which is pivoted on the same pivot or shaft,f, as the rocking dog, E. Projecting laterally from the latter and in front of the hammer is a pin or stud, h. The sear, z', ofthe trigger, F', is arranged to catch upon the shoulder, a, at the rearmost lower part of the hammer when the latter is cocked, the sear being pressed to its place by a spiral or other-.suitable spring, j, as shown in Fig. 2. In the chamber, d, Ot` the barrel lug is placed the main-spring, G, the free end, la, of which rests upon the toe, m, of the hammer. The too great expansion of the main-spring when lifted by the outward or upward movement of the barrel is prevented by a cross-pin, f, extended through the walls o f the barrel-lug, as shown in one clearly in Fig. 6. Then the breech is thrown open by end of the barrel, the pin, e, as it rises acts upon the rocking dog, E, to swing the latter backward, thereby causing the stud, h, to press against the front of the hammer and turn the same backward to full cock in which position, as just mentioned, it is caught and ,retained by the scar of the trigger until Such time as a pull on the trigger releases it. When this cooking action has been secured 'the pin, e, may pass out of the fork, g, of the rocking dog. inasmuch as the main-spring `is carried upward with the barrel its pressure uponthe toe,.m, of the hammer is reduced or released while the latter is being cocked,

thereby insuring an easy and practically unelevating the rear resisting movementof the hammer in coming to a cocked position as described. Then the barrel is brought downward to close the breech the, depression of the main-spring compresses it upon the toe of the hammer to afford the" to its original position in front ot`bnt ont of f the way of, the hammer during the forward or descending motion of thesame. The barrel is locke/d in its depressed condition, with the breech closed by the recoil block, c, by means of the operating lever, H, at the outer and upper end of a rockingbolt, I. lThe forward end of this lever is shaped to form a catch, n, which, as shown in Fig. l, engages in arnotch fr, in the rear of the shank, s, which extends back frpm the barrel. \Vhen the lever ismoved sidewise as, for example, toward the right, the catch, fn, is brought laterally out of the notch, fr, thereby releasing the barrel/and permitting the breech to be swung upward to open the same.'

I Upon the lower end of the rocking bolt, I, is a radial stud, u. A'spring, w, attached to -theadjacent surface of the frame or of the stock as the case may be, is so applied to the rocking' bolt as to tend to normally turn the same to the positionv in which, when the breech is closed, itwill engage with the notch, r. The lever being actuated to release the barrel, and the rear of the latter raised to open the breech as described, the backward movement of the rocking lug, E,ibrings it beside the stud, u, of the rocking bolt in such manner as to prevent the return of said stud, ja, to its normal position, thereby keeping the catch, n, clear of the path of the shank, s, to permit the latter to resume its place when the breech is closed. The act of closing the breech throws the rocking dog, E,forward, bringing it away from its blocking position with regard to the stud, u, and permitting the spring, zo, to turn the rocking bolt to bringthe catch, n, into the notch, r, to lock the breech-end of the barrel down in its place.

K is an ejector the stem B of which is capablo of a longitudinal movement in a guide, provided in the barrel underneath and longitudinal with the same. Around this stem is the usual ejector spring, C.

Pivoted at, a', in the walls of the two chambers, (Z, (when as shown in the drawings the firearm is double-bai'1'eled,or in the walls of a single like chamber when the firearm is single barreled) is an ejector sear, D', the rear end of which is provided with a laterally projecting stud, b', which ext-ends below the main-spring in such manner as, on occasion, to be acted upon thereby. This ejector scar, D', has a shoulder, c', and its nose or forward end, ff, projects relatively underneath a xed stop, d', at the front of. the breech re- The shoulder, h'. vtion, holding forward the safety catch, L, the,`

ceive'r` The ejector stem, B', has a circumferential slioulder,e. When the main-spring -is fully expanded as when'the barrel is depressed to close the breech, it acts upon the lateral stud, b', to depress the rear end of the ejector scar and consequently lift the forward end thereof, thereby bringing its shoulder, c', intosuch relation with the shoulder, e", as to engage therewith when the ejector with its stem is forced forward to its place when the barrel is depressed to close the breech.

The ejector, K, is arranged in the usuai or in any suitable manner in such relation with the recoil block, c, that the act of closing the breech by the depression of the rear end of the barrel forces forward the ejector to its place snug to the breech.l This d'one the shoulder, c', of the ejector scar, D', catches against the shoulder, e', ot` the ejector stein and so long as it remains holding against the saidl shoulder, e', holdsthe stem and consequently the ejector against any backward or ejectinr,l action. This continues until in the opening of the breech, the nose,f, of the ejector scar,

D', conles'in contact with the iztedshoulder,l

d', whereupon the upward movement ofthe parts relatively depresses the forward end sition prevents the operation of the trigger` and consequently ofthe hammer, and at the back is provided with a shoulder, h. Alel ver, M, the fulcrum of which is shown at 7a',

has its forward en'd arranged to engage with the shoulder, h', while its rear end, b as shown in Fig. 2, projects downward through a suitable slot P provided in .the under side IIO of Ithe grip of the stock, and in convenient proximity to the trigger, F', and behind the' same. Aspring, m', tends to keep the forward end of said lover engaged with the When the lever is in this posiiip, g', of the latter is crowded upon theitrigger as described and therebyprevents the trigger from yielding to any pull upon it,and prevents the accidental discharge of the tirearm. By forcing inward the rear end, 1)",0f

the lever, M, which maybe readily done in practice by the use of fingers not engaged in manipulating the trigger, its inner end is depressed and releases the safety catch, L, permitting its lip, g', to slip from the trigger, and thereby discngage the latter to permit its action in tripping the hammer. Y Said lip is of course so shaped 'as to yield to the upward pressure of the sear when the safety catch is released from the retaining action of the lever, M, behind it.

As hereinbefore set forth the combinations of yparts may be used in single-barreled guns, and for double barreled guns require to be simply duplicated. It is to be noted, however, that the rocking dog, E, need not be duplieated iu such case for the reason that by providing duplicate pins, h, one at eachside thereof, it is enabled to act in due operative relation with the two duplicate hammers and their duplicated adj uncts in double-barreled guns.

In Figs. 5 to 8 inclusive, which more particularly show the invention embodied in a doublebarreled firearm, the parts shown in duplicate are indicate by duplicatefreference letters, thus, for example, each of the duplicate main-springs is indicated by the reference letter, G. It is further to be remarked that with the safety catch, L, and the lever, M, as with the rocking dog E,thereis no need of duplication when Aapplied in double barreled guns, inasmuch, as the safety-catch is, in such cases, made of suchfwidth as to catch upon the triggers of both barrels asindicated in Fig. 4.

What I claim as my invention is- 1. In a firearm of the class specified, the combination with a barrel, A, provided with and carryingr a pin, e, a hammer and tripping sear, of the rocking dog, E, forked at its front end to straddle the pin, and having atits upper or rear part a pin or lateral projection,h,'
