SPECIFICATION formingpart of Letters Patent No. 695,574, dated March 18, 1902. Application filed March 21, 1901. Serial No. 52,225. (No model.)

To 1r/ZZ whom t may concern: Beit known that I, JOHN B. MAHANA, a citizen of the United States, residing at Kelso, in

Ythe county of Cowlitz and State of Washingof parts, and facilityof repair inthe event of derangement.

A special object of my invention is to so constructand arrange the action ofa magazine-gun that the user shall be able to retain it at his shoulder and without changing the position of either hand discharge and reload until the magazine is emptied, the arrangement being such that in whatever position the gun is held the Vmagazine will operate equallywell in loading, tiring, or in discharging the empty shell, which is discharged or thrown from the gun at one side (here shown as the right-hand side) instead of backward, as is the case with many other forms of magazine-guns. The magazine is capable of holding six cartridges; but it may be readily lengthened to hold more and mayalso be conveniently reilled without the removal from the gun of any part or element, the magazine containing the entire mechanism for feeding cartridges to the barrel and throwing out the empty shells, and may be easily removed from its socket when necessary for repair or cleaning.

The invention further relates to means for locking the tiring-pin against movement while the gun is being loaded, said means consisting of simple and positive mechanism which releases the firing-pin only at the proper moment, so that a premature discharge of the gun is impossible.

The principal objects of my invention having been thus set forth, a more detailed de- .magazine detached.

scription of the general structure will now be given, reference being had to the accompanying drawings.

Figure l is a side elevation of that portion of a magazine-gun containing the action or working parts made in accordance with my invention. Fig. 2 is aplan ofthe same. Fig. 3 is a longitudinal sectional view, the breechbolt being in firing position. Fig. 4 is a similar view, the breech-bolt being retracted and a new cartridge brought vinto position for loading. Fig. 5 is a similar sectional View showing the position of ythe parts after the gun has been fired and as the reloading is about to take place. Fig. 6 is a side view of the sliding bar by means of which the cartridges are pushed into the barrel of thegun and the empty shells withdrawn. Fig. 7 is a front end viewof the same sliding bar. Fig. 8 is a section of said baron the line 8 8 of Fig. 6. Figs. 9 and 10 are respctivelyaside and a rear view of the actuating-lever, the cover-plate being removed. Fig. 11 isaside view, on a smaller scale, of the entire gun. Fig. 12 is a horizontal section on the line 12 12` of Fig. 13. Fig. 13 is a vertical section of the gun-frame on the line 13 13 of Fig. 12. Figs. 14E, 15, and 16 are cross-sections of the gun on the lines 11i 14, 15 15, and 16 16, respectively, of Fig. 3, Figs. 17 and 18 are respectively aside and a rear view of the Fig. 19 shows a detail hereinafter described.

Similarletters of referenceindicate similar parts in the several figures.

A indicates the stock, B the barrel, and C the frame. The frame C is hollow and consists, mainly, of two side plates c c', Fig. 12, in each of which is formed part of a dovetail groove c2 c2, Figs. 12, 13, and 16, for supporting and carrying the breech-bolt D. The side plate c is integral with the'gun-frame, while the plate c is removable therefrom and held in place by suitable screws. The forward part of each groove c2 is cut away, as at c1, Figs. 4, 5, 12, and 13, to form an abutment or stop, as hereinafterexplained. In each plate c c' is a curved opening O for the insertion of the forefinger when the gun is to be used.

Fulcrumed nponta pin E, passing transversely through the portion C, is the actuat- IOO ing-lever F, having a circular hole f made therethrough and in line with the curved opening CZ -Aingerf' projects upwardly and an extensionf2is prolonged downwardly from the actuating-lever through the bottom of the portion C, running backwardly beneath the stock in the form of an arm F10, which terminates in a finger flo, as shown. The forward edge of the actuating-lever F is provided with two lugs fsfl, their function being hereinafter described. A recess F', Figs. 9 and 10, is made in the actuating-lever behind the opening f, within which recess a trigger G, pivoted at g, is carried. A plate F2, Fig. 10, covers the recess, being secured by screws to the actuating-lever. The trigger G has a curved end g for receiving the pressure of the linger projecting within the holef of the actuating-lever F and a shoulder g2 fordisengaging the searJfrom the hammerH when said trigger is pressed.

Above the actuating-lever F and adapted to be moved longitudinally in the grooves c2 in line with the barrel B is the breech-bolt D, carrying longitudinally therein the firingpin I. A seat d is formed in the underside of the'breech-bolt, into which is fitted a recoil-block D2, pivoted at d10 to the breechbolt. Depending from theunder side of the recoil-block D2 is a slotted .lug CZ', which engages the pin f5 on the actuating-lever F. When the gun is ready for firing, the recoilblock D2 isdrawn down into the cut-away portions or against thev abutinents cl2 of the side plates, as seen in Fig. 3. The upper surface of the block D2 has formed thereon an angular rib d2, which engages with a notch t' in the firing-pin I, locks the same at all times, except when the gun mechanism is in the position for firing, by which means a premature discharge is prevented. The rear end of the breech-bolt D is slotted, as shown in Figs. 2, 3, dac., within which slot the hammer H passes to strike the firing-pin. The forward end of the breech-bolt D is practically cylindrical in cross-section (see Fig. 7) and carries on its right-hand side what I term a curtain D for the purpose of closing the upper part of the magazine M after the empty shell has been thrown out and the gun reloaded. Extractors d5 on the forward end of the breechbolt serve to withdraw the empty shell.

H indicates the hammer, which is pivoted at Zt and actuated by a flat spring H', pressing against a strut H2, bearing on the hammer. The hammer H has a hub h2, in which are formed two notches h2 h4, the former holding the hammer at half-cock, as represented by dotted lines in Fig. 5,. while the latter retains it at full-cock. One end of a sear J, situated between the hammer and the trigger, engages at the proper time one or the other notch h2 h4 and is held in engagement therewith by a springj. The other end of the sear J is in position to be struck by the shoulder g2 of the trigger when the gun is to be discharged.

From the breech end of the barrel B rearwardly for a suitable distance the side plates or walls c c' of the frame C are cut away for about one-third of their height, (see Figs. 12 and 13,) the remaining partmade thinner, and the bottom removed, thus formingachannel K through the frame C in a vertical direction. Within this channel the magazine M is placed.

Referring particularly to Figs. 3, 14, l5, 17, and 18, it will be seen that the magazine M consists of two main parts-a lower rectangular portion or box M and a cylindrical upper part M2, the axis of which lies in a horizontal plane, a portion of its right side and bottom being eut away, as shown in Figs. 14 and 15. lVithin the boxl M', the internal width of which is slightly greater than the rim of the cartridge to be placed therein, is a carrier N, on which the cartridges rest and by which they are elevated at suitable times by means of a spring O, one end being secured within the fore-stock, the other end passing through a slot in the front wall of the magazine. Guiding-pieces m, secured to the front and rear Walls within the part M of the magazine, have their opposing faces curved, that the cartridge may move with greater ease, and separated a distance equal to the length of the cartridges contained therein. Projecting laterally from each side of the carrier N are two pins n, which pass through slot m in the side walls of the magazine and project a short distance into groovesk Za, formed in the side Walls of the channel K. (See Figs. 12 and 13.) To return the carrier N to the bottom of the magazine for the purpose of refilling, a yoke L, Figs. 1, 3, 4, and 5, is used. This yoke kconsists of two pins Z Z' and a connecting-plate Z2. The plate Z2 lies close against the forestock a short distance in front of the magazine (see Fig. 1) and is adapted to be rocked or vibrated on its pivot formed by the pin Z, journaled in the fore-stock. The pin Z at the other end of the plate Z2 passes through a curved slot b2 into the interior of the forestock above the spring O. When the yoke L is swung downwardly on the pin Z, the pin Z' carries the spring O with it, and consequently the carrier N. When the yoke is raised, the spring naturally follows. A stop 127 holds the yoke in its two positions.

Pivoted within the cylindrical portion M2 of the magazine is the intermittently-rotating cartridge-feeding and shell-discharging device P, consisting principally of a shaft j), to which is fixed a body carrying four curved arms p2, their normal position being that shown in Fig. 14. The rear end of the shaft p carries a spring-controlled stop-wheel P and a ratchet-wheel P2, the latter being rotated intermittently by mechanism operated by lugs f2 f4 on the actuating-lever F.

The mechanism for rotating the arms p2 may be briefly described as follows: Arranged to slide vertically in bearings m12 on the rear wall of the magazine is a rod Q, the

lOO

IIO

upper end of which is formed into a spring andl adapted to engage the ratchet-Wheel P2. A finger Q6 projectsa shortdistance rearwardly fromthe rod Q and is then bent laterally, so as to lie in the pathway of the lugsl f3f4, heretofore described. When the actuating-lever is drawn back, the lugj4 strikes the finger q'j ust before the actuating-lever reaches the end of its movement. Thisl movement raises the rod Q and turns the Yratchet-Wheel one-quarter of a revolution, there being but four teeth on the ratchet-wheel. A springp4 'bears against the stop-Wheel P and `holds it against further rotation. AsA the actuatinglever returns the lug f2 strikes the stud-gf and drarrs down the rod Qinto position for` another quarter-turn of the ratchet.` Each "movement of the ratchet throws ou tthe em pty shell and brings a new 'cart ridge into loading position. f

For the'puifpose of supporting the cleaningrod the stock of my gun is bored, as at Ct,

Fig 11, in which is placed a telescopic cleaning-rod. A cavity is` also formed in thestock for Vcarrying patches and closed by acover a2;

The barrel B has two lugsb b' depending from its Vunder side, Which-fitin suitable slots iin `the fore-stock,fthe lug b' being heldbya swinging hook b2, locked in position by a spring-catch b3.' Y

The operation of my invention is as follows:

Assuming the magazine tobe empty and the parts in the position shownin Figs. 3 and ll,

las

except that the hammer rests on the tiri-ngpin, the first operation to be performed is'that of loading the magazine. The gun is heldin the left hand, forward of the magazine, While withV the 'right hand the yoke L is operated to depress the spring O and loi'ver the carrierN. The forefinger of theright hand is then placed in the holefot' the actuating-lever and the said lever drawn back. The `first movement of the actuating-lever raises'tlije recoil-block D2 from the labutment C10 and into its' seat d in the breech-bolt D, by reason of the connection of` the fngerf and lug d', (see Fig. 5,) carrying the rib d2 into the notch t' in the tiring-pin, -thus `locking it 'securely against movement in any direction. bolt D after the recoil-block D2 becomes disengaged from the abutments and seatsitself is carried rearwardly bythe flngerf until the limit of movement-has been reached, (see Y spring p4 with the stop-WheelP. This movement of the shaft p turns the arms p2'sufticiently to eject through the open side of the magazine the 'empty shell should one have been'in the gun. It willV be understood that zine. lnext* two cartridges Will pass around With'the` The breech-- When thebreech-bolt D is retracted the cur-`f tain D' attached thereto will also be drawn back, thus opening the magazine. Fresh cartridges having been placed against or-upon' the arms p2, as in Fig. 15,-upon rotation of the vfeeding and discharging device P in the directionof 'the arronY the cartridges Will-fall into the magazine on coming in line With it.

"Should the carrier N be in the position shown in lo', the cartridges Would pass around with the arms instead of entering the maga- As soon asthe magazine is filledV the arms p2, one cartridge being in position for yentering the barrel, while the other is ready to be carried into'place at the next movement 4to reload. The magazine being filled, the pressure ofthe middle finger ofthe operator against the extension f1O of the actuating-'1e- 'ver Will cause said'lev'er to move forward,

carrying with it the breech-bolt D, the for- Ward-end'of which'on striking the-cartridge vwill force itinto the barrel and the extractor into engagement with the rim of the cartridge.

The cartridge having4 beenforced home, the

recoil-block D2is drawn down by-theinger f', so as to engage `the abutments 010 of the 1 grooves c2, locking, the breech-bolt D firmly `in place against the cartridge and taking the" Afull force of the recoil. l At the timethe re-A coilj-block D2 engages the abutments the rib d2 (seeFigs 5,` G, and 8)`is withdrawn Vfrom Y' the n'otch't' in the tiring-pin, leaving the lat- =ter freeA to move when' struck by the hammer.V

The magazine may be readily taken from `its s ocket by moving the breech-bolt rear- -wardlyuntilit is free of the magazine; `The L catch m10 (see Figkl) being then withdrawn from the notch m12 in the side of the magachannel. A i

`zine,`the latter is free Yto be 7taken Afrom `its The'gun is held to the shoulder in the usual inanneigthe right hand of the user grasping thev stock, his forenger passing-through the restingagainst the extension f2, his third iinger under the' arm F10, and his fourth finger above the finger f 10. It will thus be seen that the recoil-block D2 is held with great firmness against its abutments when ring. Should a cartridge-shell stick in the barrel, as sometimes happens, so that it cannot be Withdrawn by the forefinger operating the actuating-lever, the arm F10 overcomes this difficulty by its greater leverage.4 By alternately pressing the foreiinger and the middle finger the cycle of operations of loading and firing may be performed without removing the gunv from the shoulder.V
