To (LH 11i/ont [i muy emmer.-

Einiii'is, oi' llartford, in the county of llart ford and State ot Connecticut, have invented a new Improvement in lreeeh-lniading Fire-Arms; and Ido hereby deelare the following, when taken in connection with accompanying drawings and the letters of refercncemarked thereon, to be a full, clear, aml exact description ofthe same, 1o and which said drawings constitute part of this specification, and represent, in l Figure 1, a longitudinal section cutting centrally through one of the bai rels and showing side view of the foreend .and of the i5 lock mechanism, the parts being in the normal position; Fig. the same as Fig. l, showing the parts in the position which they occupy when the barrels are thrown open from the position in Fig. l Fig. 2, a transverse seczo tion through the cooking-bar, representing the pin 9; Fig. 3, a transverse section through the extractor-slide on line .r of Fig. L?, looking rearward; Fig. 4, the same as Fig. 2, showing the parts in the position alter the barrels have been returned; Fig. o, the saine as Fig. 4, showing the parts in the position when the barrels are opened without the hammer havingI been diseharged; Fig. o', a sectional side view illustrating the ejecting devices in the 3o normal position; Fig?,animderside viewot' the parts shown in Fig. t3, Fig. S, a forward em'l view ofthe arm l; with the fore-end removed; Fig. S, a transverse section through the foreend directly in front; ol' the cams, looking rearward; Fig. ti, the sameas Fig. (i, illustrating the parts in the open position, as when tliehainmers are cocked, the cani f' removed to show theoperation of the central cam o; Fig. lt), a transverse section through the frame or arm to l on line .r n of Fig. El; Fig. lll, a top view of the slides il; Fig. l l, a perspective view of one of the segmentsl nl detached; Fig. 12, the same as Fig. t3, representingl the parts 1n the open position and as after the hammers have been `i5 discharged.

the saine modification with the parts in the open position, and showing the eam just on the turning-point and undertheactionof the o strut; Fig. l5,a moditieatiim in the operative mechanism ot' the eanis, Fig. l and sneceeding tignres being enlarged.

This invention relates to an improvement in that class of breeelrloziding tire-arms in which the barrel is hung to the frame at a point forward of its lireech end, and so that the barrel will swing up from the frame in opening the breech,commonly called breakdown arms, it having special reference to those arms of this class in which the hammer 6o or hammers are concealed within the frame and are thrown to thc cocked position in the breakdown movement, the invention being specially applicable to double-barrel shotguns of this class, but also applicable to single barrels and other breakdowns.

In the more general construction of this. class ot arms the eai'tridge-retraetor is operated hy the breakdown movement, and so as to simply start the cartridge from its seat in the 7o barrel whether or not the hammer has been discharged to explode the cartrige, the starting of the cartridge att'ording the operator an opportunity to grasp the cartridge or exploded shell, as the case may he, with his tingers to withdraw it from the barrel.

The objet-t of my invention is an automatic deviee which will operate to eject the eartridge, lint; do so only in ease thehainnierhas been released and thrown to its normal posi- 8o tion to explode the cartridge, and so that in doulile-barrel arms if one barrel has been discharged and the other not the openinginovenient of the barrels will eject the exploded shell without a corresponding ejeoting movenieiitof the uncxploded cartridge; ahd thein- Vent ion consists in the mechanism hereinafter described, and particularly recited in the claims.

A represents the frame, from which an arm 9o l; projects forward. and to which arm the fore-end (t is hinged in the usual manner.

E represents theliarrels, securedto the foreend, and so that turning the barrels 'forward and downward upon the pivot will` open the lireeeh and a corresponding return movement will close the breeeh in the usual manner.

F represents one hammer, linng in the frame npoii a pivot (l.

ll represents one arm ot' the mainspring, loo

which carries a roller I, that works upon a bearing-surface in the frame and extends forward. ',lhe other arm, returning, terminates in a cam-like end J, which bears upon the hammer forward of its pivot.

l represents the scar, hung upon a pivot L in rear of the hammer, its nose adapted to engage the cock-notch of the hammer, its tail, extending rearward, adapted for engagement with the trigger M.

N represents the eocking-bar, which ishung by its forward end to the upper side of a rock-shaft l), arranged transversely through the forward end of the arm l. The bar N being engaged with the roelcshaft upon its upper side, as at (Q), extends rearward, and at its rear end is constructed with a shoulder P, adapted to engage a pin R on the hammer, and so that as the rock-shaft l) is turned forward it will draw upon the bar N .and bring the hammer to the cocked position, as seen in Fig. '2, at which point the hammer will be engaged bythe scar, as also seenin Fi"- C' and l o* a so that the barrels majv then be returned, leaving the hammers at full-cock and readjv for discharge. i

The usual interlocking devices for seeurY ing the barrels in the closed position are provided and not necessary to be described. The rockshaft is connected to the fore-end by means of studs D', which project through vertical slots D2 in the forward end ofthe arm li, (see Fig. 3,) the said studs passing through corresponding openings in the rear end of the fore-end, so 'as to engage the fore-end, that when the fore-end is turned, as from the position seen in Fig. t to that seen in Fig. 2, the rock-shaft l) will be cori espondingly rotated. The forward end of the mainspring engages the locking-bar N, so as to partake of its backward-aiid-forward movement, and whcreby the mainspring is partially compressed dnringthe opening movement, as vfrom Fig. l to Fig. 2, and then on the return movement the cam-shaped end J of the mainspring rides onto the bearing upon the hammer, so as to complete the compression of the mainspring, as represented in Fig. l.

As thus far described the construction is substantially the same as that described as the invention of William Mason in Letters Patent of the lin ited States No.2t3il,ltl1,dated August 22, 1882, assigner to the assignees in this application.

S represents the ejector-slide, which is arranged to slide longitudinally between the barrels in thc usual manner; but instead of being made in the form of a single bar it is divided, as indicated in Fig. il. Each slide is provided with an independent ejector T, these cjeetors being substantially the usual ejector for double-barrel guns secured to the end of the slide, except that the ejector is divided, so that each part is in connection with its own particular slide, and so that each may be moved independent of the other.

In the fore-end t, and near the joint between it and the arm l, a transverse pivot U is introduced, upon which three cams a l c are hung so as to swing in a vertical plane. The cam a is in a 'vertical central position in a plane between the two barrels, and so that its nose d may normally bear against the rear end of both ejector-slides. The two cams 11 c, being upon opposite sides of the cam o, are adapted to bear each against its own respective ej ector-slide. ln the fore-end helowthe cams two followers j' are arranged and so as to slide longitudinally. The tail q of the cam a bears against the forward ends of both these followers, as represented in Figs. t3 and 7. The noses of the two cams l) c normally stand in a position as bearing against the forward ends of the respective slides S, as does the nose of the cam u. 'lhe lower ends h i of the respective cams l c stand in the path of the respective followers cf, as seen in Fig. 7; but the lower ends of each of the cams I c normally rest against a stop l, which holds the said cams a short distance away from the ends of their respective followers, as represented in Fig. l.

In the opening movement of the barrels if either follower be thrown outward to a limited extent such movement of the follower will impart to the central cam o a rotative movement before the said follower can reach its cam h or c, as the case may be. Under such movement of the followers,therefore, thecentrai cam will receive a movement in advance of the two cams I) f', and such movement of the central cam will impart a corresponding longitudinal or retractive movement to both ejector-slides. Then a further movement of either of the followers will bring such follower into contact with its cam l; or c, as the case may be, and then that cam Il or c will move under the continued movement of its follower, together with the central cam o.

0n the shaft l), and in recesses in the arm l around the shaft l), segments m are arranged eoncentric with the shaft, one for each of the followers c j'. One of these segments is shown detached in FigA 11. The recesses in which the segments are arranged are of a length greater than the length of the segments, and so that when the parts are in the closed or normal position, as seen in Fig. G, a space n will be left in the segment-recess between the rear end of the segments and corresponding shoulders 0 in the frame. These two segments are represented in broken lin es, Fig. 8, also seen in Fig. 1U. At` the forward end each segment is constructed with an inward projection )aand these projections 11 are constructed with seats s, (sce Fig. 8,) in which the inner ends of the followers c frcspcctively rest. The ends of the followers which so rest inthe seats s are of cam shape, as seen in Fig. l).

In breakingdown the arm-that is, in turning from the position in Fig. G to that seen in Fig. tlthe followers and the cams swing with l the fore-end, and as the followers bear upon IOC l cams Z) e in like manner r-,or either of them, be turned upward, the result ot' such movement of the cams is to bring such strut into line between the axis upon which the cams turn and the seat of the strut on its piston. New, if the movement of the cam be continued above this point, as seen in Fig. 12, so that the end of the strut is brought to a position above the said line, the reaction of the spring upon the strut will then tend to force the strut rearward against the cams and impart to the nose of the cams a rearward movement, as indicated in broken lines, Fig. 12. It will be evident that if the followers are forced farther forward than when in the previouslydescribed opening movement of the barrels it will correspondingly turn their respective cams Z; e, and will also continue the turning' movement of the cam e'. The nose of that cam o, being, therefore, in advance of the nose of the respective cams l; c, will correspondingly move the ejector-slides in advance of the noses of the cams b r, and it will also be seen that if the segments be stopped earlier than upon the shoulders o the action of the seg- `ments upon the followers will occur earlier and produce a corresponding greater extent of movement of the followers.

The movement which I have described, with the segments coming to a bearing against the shoulder o, is that which oecu rs when the ham mer is in the cocked position, and so long as the hammer remains in that cocked position the movement of the segments will be, as I have described, from the normal position until they come to a bearing against the shoulders o.

As the ejection of a cartridge is not desirable unless the hammer has been thrown forward to explode the cartridge, I utilize the hammers to operate in connection with the segments to leave the segments free to reach the shoulders o when the hammers are in the cocked position, or to interpose a stop for the segments at an earlier point when the hammers, or either of them, are discharged. 'lo thus .utilize the hammers, I arrange a headed pin il vertically through the cooking-bar N, the head of the pin adapted to rest upon the upper side of the bar N and directly below the arm J of the mainspring, so that the tendency of the mainspring upon the pin 9 is to force it downward, as seen in Fig. l, when the hammer is in the normal position. t`omhined with this pin .fl is a spring 10, very much lighter than the mainspring, the tendency of which is to raise the pin il. W'hen the hammer is thrown to the cocked position, as seen in llig. 2, the pin is free t0 rise under the action of its own spring 10, and as the arm .lof the mainspring rises the pin 0 rises accordingly, as seen in Fig. f2, and when the hammer is returned to the normal position, as seen in Fig. l, then the pin 9 will be forced to its down position. Forward of this pin and between it and the pivot fl) a longitudinal slide Vl1 is arranged, the rear end of this their respective seats in the segments they will turn those segments until the said segments come to a bearing against the shoulder o, as seen in Fig. fl. At this point the further movement ot' the segments will loe arrested; but the followers and the cams will continue their movement with the fore-end. The cam-shaped ends of the followers and. the correspondingseats of the segments now come into action, thc result of which is to throw the followers forward to the position seen in Fig. t), and such forward movement of the followers will act upon the central cam u and turn it accordingly, throwing its nose rearward to the position indicated in Fig. il, the broken line t representing the position of the nose of the cam before such movement. This movement ot' the cam will impart a corresponding rearward movement alike to both ejectors, and sntiicient to start both cartridges or shells, as the case may be, from theirseats in the barrel, and sutlicient to enable the operator to grasp the heads to remove the shells or cartridges should he desire to do so. If from this open position in Fig. 9 the barrels bc returned, the cam a and followers return therewith, and as the closing position is approached the followers come to a bearing upon the upper side u ot' the seats s in the segments, and then in completing' the closing movement this engagement between the followers and the segments will return the segments to their normal position, seen in Fig. li. vIn this movement it will be observed there has been no action upon the cams l: r. In this closing movement the cjcetors will strike the recoil-plate of the gun and be forced inward in the usual manner, and this movement of the ejector-slides will force the cam u. back to its normal position.

In the fore-end (l, forward of the respective cams, longitudinal recesses 2 are formed, (see Figs. t5 and 7,) in cach of which a piston is arranged, and in the recesses, l'orward of the pistons, spiral springs are introduced, the tendency of which is to force thepistons rearward, and between each et' said pistons and the back of the respective cams Z1 e struts t are arranged, one end ot' the struts taking a seat on the piston, and the other end of the struts rest upon seats 5 in their respective cams. 'lhe seats 5 `in the respective cams, when the parts are in the normal positioli,as seen in lfig. marc at points on the cams below a line drawn between the center of the axis upon which the cams turn and the seat for the struts on the pistons, so that the struts stand in a downward and rearwardly ini clined position, the result of which is that the springs bearing against the said pistons and through the said struts yieldingly hold the respective cams against their respective stops l. Stops are arranged, as seen in Fig. l, to arrest the upwardmovement of the as the stop l arrests their descent, broken lines, Fig. (l, indicating' such stopped position. lt the rams I;

slide standing directly forward of the pin t) when the parts are in the normal position, as seen in Fig. 1, but so that when the hammer is in the cocked position, as seen in Fig. 4, the pin 9 will be raised so far as to escape the slide in the forward movement of the pin, and so that the pin will pass over that end of the slide 1l, as seen in Fig. 5. Consequently when the hammer is in the cocked position the pin 9 has no effect upon the slide 11', but when the hammer is in the normal or closed position, as seen in Fig. 1, the pin stands in rear of the rearfend of the slide 1l, and so that in the forward movement of the pin the slide will be forced forward, as seen in Fig. .2. The position of the lower arm of the mainspring is such with relation to the pin J that the pin 9 cannot escape under the action of its own spring 10 from engagement with the slide 11 until the open position of the barrels is reached, as seen in Fig. 2. Then the pin, under the action of its own spring 10, has risen out of engagement with the slide. An independent slide 1 l is arranged for each segment.

The forward end of each of the slides 11 is constructed with an inward fiange 12. (See Figs. 1() and 10.) These projections extend through a slot 14 in the frame and normally stand in rear of the spaces n and shoulders o, as seen in Figs. 6 and 9; but under the forward movement of the slide 1l, as before described, the said fiange 12 is brought into a space `n and below the shoulders o, as seen in Fig. 1:2, and so as to form a bearing against which the segment m may come to a stop at a point earlier than the shoulders o. The result of this earlier stoppage is to bring the seat s of the segment to an earlier action on the follower e, and as seen in Fig. 12, which represents the fore-end at its extreme open movement. In this position, it will be observed, the rear end of the strut l has been raised to a point above a line drawn from the pivot of the cam to the seat of the strut on its piston. As the downward or opening movement is being completed the seat between the cam and the strut 4 passes above the said line between the center of the pivot and the piston-seat of the strut, as seen in Fig. 12. Then the action of the spring through the strut upon the cam is to turn the cam rearward, which it is free to do, there being nothing interposed other than friction to prevent such rear movement of the cam and the ejector-slide, and the cam will be thrown under such action of the strut until it is arrested by a suitable stop. lVhen this rearward action of the strut commences, the nose of the cam upon which the strut acts stands forward of the rear end of the ejectorslide by so much as the nose of the cam @has been moved in advance of the cam upon which the strut acts. The result of this action of the spring-strut upon its cam, therefore, is a quick accelerated movement of the cam, which will bring its nose against the forward end of its ejector-slide, giving to it a blow, as by a hammer, and of a force sufficient to give to that ejector-slide such a sudden rearward movement as to enable it to throw the exploded shell, or the cartridge, if it be not exploded, entirely from the barrel, and as indicated in broken lines, Fig. 12. On the return or closing movement of the barrels the ejector strikes the recoil-plate of the frame, as before mentioned, returning the ejector to its place in the usual manner, which imparts a returning movement to the cam until the forward end of the strut has passed below the said line between the pivot of the cam and the piston-scat of the strut, as indicated in broken lines, Fig. when the strut will, under the action of its own spring, return to its normal position, as seen in Fig. G.

The shaft D is constructed with a cam-recess in its periphery, forming a cam 15, (see Figs. l and 2,) adapted to operate against the corresponding forward end of the slide 11. \Vhen the barrels are opened and the slide 11 moved forward, as 1 have before described, the forward end of the said slide 11 passes below the cam 15 of the shaft l), (see Fig. 2,) and so that as the barrels are returned the said cam 15 operates upon this then-projecting end of the slide 1l,and so as to force the slide to its rear or home position, as seen in Fig. 1. The opening movement and return of the barrels which l have thus described leaves the hammer in the cocked position, as seen in Fig. 4, and so long as the hammer remains in the cocked position the pin t) will be held up out of possible contact with the slide 11, and so that the barrels may be opened, and, as seen in Fig. 5, without operation upon the slide 11, but so soon as the hammer is'discharged the arm J of the mainspring forces the pin D downward into position to engage the slide 11. lhile the hammer stands in the cocked position the movement of the ejector will be limited by the shoulder o in the frame, against which the segment bears, as first described. The result of this is that the ejector will be moved but a short distahce and without an ejective action, and so as to only start the cartridge from the barrel to be returned as the barrel is closed; but after the hammer has been discharged and the slide 11 thrown forward to earlier arrest the movement of the segment the increased movement will be imparted to the ejector-cam and the ejeetive or accelerated action which 1 have described will be the result. It will be understood that a like slide 11, with its flange l2, is employed for each of the segments, and so that upon the discharge of either hammer its particular slide 1l will be thrown forward to bring the iiange or auxiliary stop 12 into position to arrest the rotative movement of that hammers segment. So long, therefore, as both hammers are in the cocked position there will be no ejective force applied to the ejector-slide; but after the discharge of one hammer the opening movement of the barrels applies the ejective IIC IIO

force to the barrel with which that discharged hammer operated, and so as to eject the shell exploded by such discharge of the hammer, (or cartridge, if it be not exploded,) while the other hammer not having been discharged its cartridge will remain in its place. Il", however, both hammers be discharged, then upon the next opening of the barrels the shells from both barrels will be simultaneously ejected. Thus either barrel may be fired, according to the desire of the operator, the shell from the barrel tired being ejected, while the cartridge of the other barrel will remain in place, the ejection from each barrel being independent of the other, and the ejection can only occur after the hammer has been discharged.

The intermediate cam a may be omitted and the two outside or independent cams cmployed. An illustration of this modification is represented in Figs. lil and ll, thc representation of one cam being sufficient for illustration. In this case the tail of the cam, instead of standing normallyout of reach of the follower e, rests against the follower, as seen in Fig. 13, and the strut bears upon the cam, as before described; but in this arrangement recesses U are made in the cams above the seat 5, in which the Struts normally rest, and so as to form a seat 7 ata distance above the seat 5. In the opening movement of the barrels, as in cooking the hammer, both cams in this ease will start with the followers and move to a distance corresponding to the distance heretofore described for the caln u, as seen in broken lines, Fig. il, and will give to the ejector-slides the correspomling initial movement, and this will occur before the seats 5 of the struts have reached apoint above the line through the axis on which the cams turn, so that such initial movement of the cams will not turn them so far as to bring the struts into action, it being understood in this ease that the struts are inclined downward to a greater extent than in the first description, and as seen in Fig. lll; but on the increased movement of a follower, as by the earlier stopping of, the segment, a correspondinglyincreased turning movement will be imparted to the cam, and so as to bring the seat 5 oli' the strut above the line through the axis of the cam, as seen in broken lines, Fig. ll, and when this point is reached the strut will lly to its uppositioinas indicated in broken lilies, Fig. lll, and in so doing will give to the cam and to the ejector-slide an aeeeleratel'l movement corresponding to the blow of the cams heretofore described. Under the modification which l have thus described the see'- ments operate the same as before until they stop against the shoulder o, as seen in Fig. ll. '.lhe continued opening movemcntof the barrels forces the follower outward, and so as to turn the cam to give the preliminztry movement to the ejector-slide,butnot to an extent sufficient to bring the strut above the line between the axis of the cam and the seat of the strut on its piston, and as represented in Fig. il; butil theauxiliary stop 12 be brought into action, as before described,to earlier arrest the rotative movementof thc segment m, then the follower will be forced farther forward,and so as to turn the cam with the strut into the position seen in broken lines, Fig. 14, when thc strut will be foiced upward in the scat of the cam, and so as to impart the blow, as before described. l, however, prefer the employment of the three cams.

While l prefer to employ the followers ef asa means of operatingthe cams from the segments, the tail of the cams may extend into the seat in the segments, as seen in Fig. l5, so that the segments will act directly upon the cams, with substantially the same result.

The modilications which l have thus illustrated will be suflicicnt to enable others skilled in this art to introduce other meehanism between the hammers and the cams to impart the required movement to the cams, it only being essential to the invention that that movement shall he imparted in the openingl movement of the barrel through an operator in rear of the cams, and between the cams and the hammer, the said operator having a movement imparted-to it in the opening movement of the barrels, with meehanism between said operator and the hammer, whereby the said operator imparts a greater movement to the cams when the hammers are in the discharged. position than when in the cocked position. vI ther fore do not wish to be um'lerstood as limiting the invention to the precise construction lirst described whereby the objects of the invention are attained.

l have described the invention as applied to double-barrel guns; but it will be understood the invention may be advantageously employed in single-barrel breakdown arms.
