MACHINE-GUN.

"To all whom it may concern:

Be it known that I, ROBERT F. HUnsoN, a citizen of the United States, residing"at Richmond, in'the county of Henrlco and State of Virginia, have invented certain new and useful Improvements in Machine-Guns, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in machine guns, one object of the invention being the provision of positive means by which the cartridge is delivered to the breech of the barrel, is retained in such posit-ion during'the firing operation, and theyempty shell or even in case the cartridge should be unexploded, itis removed from the breech of the barrel and released to move or ran in an opposite direction to the oncoming new car- A. further object of this invention is the provision of a machinegun in which the firingmechanisms are preferably arranged in; pairs and whereby a plurality of barrels may be'employed so that an exceedingly effective defensive weapon can be provided and one which will positively tact, and in which one or more barrels will be discharged at a time. p 1 f f A still further object'of this invention is the provision of a machine gun which elimi nates the defects due to jamming ashas been discovered in all guns using the recoil or gas to operate the breech block, inasmuch as in-the present mechanism a snapped. cartridge will. be withdrawn from the barrel I g as rapidly as an exploded shell;

, mechanism.

In the accompanying drawings z;v Figure 1 is a side elevation of the com plete gun, the lower. part of the tripod being broken away.

Fig. 2 is a'front elevation thereof. Fig. 3 is a rear elevation thereof. Fig. 4 is a top plan Viewv thereof. 7 Fig. 5 is a horizontal sectional view through the breeches ofthe rifle, showing the relative positions of'lthe breech block Fig. 6'is an enlargedde tail section on line 6-6 of Fig. 5, showing the parts in the position they assume when having placed a cartridge in the barrel and'just previous to the explodingthereof- Fig. 7 is a similar view to Fig. 6 show iIlg the breechjblock' in the position a as:

sumes after having released a spent shell and previous to the delivery of a' cartridge.

gF g. 8 is a section through the frameaof j the mechanism substantiallyon the line 8+8 of Fig. '6,'showing the trigger setting slots,

and adjacent mechanism,

Figs. 9 and 1 0,are detail views ofvarious parts of the present machine gun.

' Referring to the drawings, the" numeral V 20 designatesa'tripod or any support by" means of which the horizontal swivel21 may be mounted'so that the mechanism-may be swung from right to left, the yoke 22m porting the rod 23;which as shown in Fig. '6, is .mounted in' the slot 24 to "cotiperate with the compression spring 251m re eeivethe recoil of the gunand atthe same time to permit variouselevations fas the rod 231prbvides a means 'forpermitting vertical swing: ing movement of the complete mechanism. The projection 26 carries the. spring 25 and also thecomplete gunmechanismg- Carried at the forward portion thereof, isthe'plate 2? having aplurality of interiorly threaded socketsj28 for the'r'emovable reception of the gun barrels 29. ,VVher'emore than one of the barrels are employe d, the sockets 28 are so arranged as to permit of a fan-like arrangement of the barrels, it being intended that ata range of 1000 yards that the bullets fired from the various barrels. "will be' The'barrels therefore will 1 r 18 inchesapart. I not be absolutely parallel.

- Surrounding thebarrel s, eitheronegat-a time or all of them, is the water jacket 30 byineans of whichtheyare' cooled. Any

desired means may be employed for cooling l l the barrels,-that here shown merelybeing an example of one method ofdoirig it. The barrel carrying plate is provided Wlthga, plurality of pins 31v for engagement in the sockets 32, the catches83 and pins 34 being employed to lock the same downwardly against movement, while the pins 35 are employed to prevent any forward tilting movement.v Abracket 36 is also employed (to insure the proper locking of the parts to the frame of the machine. V

Formed integral with the portion 26 and extending rearwardly'therefrom, are the two side plates 37 which areconnected together by" means of the plate38 provided with Pa 2 plurality of triggercocking slots 39, here ROBERT F. .rrunsoiv, or RIGHIVIOND, VIRGINIA.

shown eight in number. It will be here noted that the se'slots are arranged in fours in-stepped relation, as in a gun of this size, eight barrels, four barrels are cocked at one time and instead ofthrowinglthe fullpower in the cocking operation at one time, they are operated in succession by the respective in member'65 when 111' breech block closing slots 39, as will presently appear,

Attached to the upper surface oi the side plates 37 is the top plate 40 which as here shown, is provided with the cartridge receiving apertures 41 and the reduced slots 42 for the reception'of the locking lug .43 ofthe cartridge mechanism 44, this slot. being ex tended from the rear of the plate 40 soanumber of mechanisms beflplaced in positio'i'none after the other,the spentmagazine being automatically released when it is adjacent the slot 41 to fall over or be re moved by hand, as is necessary. Between the plates 88 and 40 is'a heavier plate 45, which is provided with substantially dovetail shaped grooves 46, one to each breech block mechanism 47, and asv each breech block mechanism'is a duplicate'of the other,

the description ofone will sufiicc'for all. Each breech block'mechanism consists of a bar 48 provided upon its under side with the rack 49, the purpose of which will pres-- ently appear, the notch 50, and with thecani end 51, while at its forward lower end it is provided with the ribs 52 and53 for the receptionof the ejector carrying block 54,

whichis slidably mounted thereon and limited in itsforward movement .by;means of the slot 55 and the pin 56. In the slot 57 or the oppositely disposedwings 58 of the member 54, there are disposed the cartridge carrying and ejecting levers 59, each one of which'is provided with the rim engaging terminal 60andthe cam engaging operating projections 61,'a spring 62 b'eingxprovided to normally hold theends 69 toward each other and in frictional engagcmentwith the cartridge C even'be'fore'the retractire movement of the breech block and. after it has been seated within the groove 63 0f said cartridge, the same maintaining its position even after the cartridge is "within the breech of the barrel, as clearly illustrated in Fig. 6. In order to release the members 59 so as to permit the empty shell'to tall and assume the position as shown in Fig. 7, there is disposed in the path of the ends 61 thereof, the pins 6, Fig. 5, it being here shown'in the position it assumes when some of the shells have been delivered to the breech of the barrels and the others' in position forbeing moved forward as gripped betweenthe eject: lng mechanism, the full barrel movement of r the breech block [causing the, cartridge to assume the position as shown in the barrel with the ends 60 in engagementwith the rim this means, whether the shell. eX-

plodes or not 'andupon the retractive movement of the block, it is removed from the barrel and released to receive the next cartridge above from the magazine.

Upon the upper surface of the block 47 at the forward end thereof and parallel with the ribs 52 and 53, 1s a tubular member 65 which guides the firing pin 66,: the tubular position assuming the position as shown'in Fig. 6, and closing the breech while the mer 69 which consists-0t asubstantially L-shaped plate 'witlrthe. terminal 70 guided underthe cross-bar17l and carrying the cylindrical rod '72 upon which. is supported spring '73 which is a compression spring and isdisp'ose l between the lug 70 and the head 69, so as to exert tension toward the tiring pin. The rear end 74 of the hammer is hingedly connected as at 75to'the hammer setting and releasing-block 76 which-is provided with a pin 77 for fitting within the I slot'YS offlthe setting sear mounted in the slot 80 of the breech blocl upon the, pin

:81. As-the' breech block is retracted in its 7 movement, the; sear having its, lowerv end 82 projected through its respective slot 39, the rear endofthe slot'is engaged and 'tlie'end S2, moved upwardly seas 'to' cause the block 76 to he slid rearwardly to cook the hammer, the lock 83du'ringthis movement engaging .over the upper end of the cam 51 of the mem ber 48 and. assuming the position as shown in Fig. 6,7with thespring 73 retractjed and the hammer cocked. V

In order to impart reciprocating ii1ovcment to the member 48, which in reality is theibreeciliblock, there is jonrnalcd transversely oi the frame, the shaft 84 which has mounted I thereon two oppositely disposed toothed segments85 and' 86, whose shaft her being shown as operated by the crank 87, although 'it i's to-be understood that this s'haft maybejoperat'echby a spring, electric or gasolene motoras may befound desirable in practice; Alsofmounted upon the hea 841s a cam 8(., hav1ng the oppos tely d sposed notches 88 and 89.

7 It may be said that in a gunof any number of barrels only two of these cams-are employed and therefore only two. of the breeehblock mechanisms 48' are provided with racks 49 so that when the shaft 84 is rotated these toothed segments 85 and 86 impart forward movement first to one breech mechanism and then the other, In view or thisffactfit istherefore necessary to'havc motion imparted from the respective breech blocksto the rcmei'ning'jones and in order to accomplish this theracks 90 and 91 are provided upon opposite sldesof the respec- 7 that any-number: of breechblock mechanisms and barrels may be employed and tive breech mechanisms so as to engagethe loose pinions 92 and therefore transmit motion alternately to the various breech block mechanisms'supported in the. frame.

i In order to lock and release the breech blocks in their. extreme forward or rearward position and at the same'time to release the hammers to operate upon thefir- 'ing pinsythere -ismounted at the rear of the frame tWo arms 93 which are guided at the rear of theframe and carry the crossbar 943-which is adapted to sit Within the notches of the respective 'mechanisms When retracted toilock" them in such posi-- tion and to extend to'the rear to engage the cam surface 51 of the projector mechanisms, the continued forwardmovement: of thebar 94: engaging the trigger 83 to raise it from engagement in-the position as shown in Fig. 6,- so as to release the memberf76 and the hammer 69 to the action'of the spring 73,

the parts being in absolute locked 'POSltlOIl beforegthis occurs. The spring 95, mounted in the casing 96," and also inthe hollow plunger 97 Which is connected to the frame 93,- normally holds the crossbar 94 up:

wardly; In order to release the cross-bar 9st, 'thecam 87 is provided, the continued movement ofthe cam riding upon the tooth 98 carried by the lever 99, Which is'pivoted at' the forWard send at theslot 100 of the frame and at the rear end as at 101 to the arms 93. This action causes the-depression of the arms 93 and the cross-bar 94against the action ofthe spring 95'so that a cross- From the foregoing description taken in connection 'Wltll the:drawings, it is evident maybe driven from a single shell andthat by means of this mechanism each alternate breech "block mechan1sm'-W1ll be simultaneously retracted andthe spent shell ejected While the others Will be projected with the new cartridge taken fromthe mechanisms to be deliveredjin the breech of the barrels. 7 It is also evident from this construction that the action; of inserting and Withdrawing the cartridge and-its shell is absolutely positive and "that should a cartridge fail to explode it ill be ejected just the same asvif it had exploded- 7 latter case a {n will also be noted, that witheach half f revolution in 'the' main shaft that in this construction four barrels will explode "and that While fou-rare being" exploded the other four are being made ready; and 'at'xthe completionof the revolution the remaining ones Will be fired. T c V w It is also apparent that this mechanism may be'used with a single barrel or any number of pairsand that'any odd number also may be=used as'may befound desirable, The present mechanism is so constructed and adapted as to take any ofthe desired calibers,'that is, rangingfrom the rifle car V tridgeto the one or tWo pounders, in the different mounting would; be
