SPEGIF ICAHON forming part of Letters Patent-No. 523,185, dated July 17, 1894. Application filed May 15,1893. Serialll'o. 473L267. .(No model.)

To all whom it may concern:

Be it known that I, PARDON B. TYLER, of Spokane, 1n the county of Spokane and State of Wash1ngton,have invented a new and Improved Machine-Gun, of which the following is a full, clear, and exact description.

hly IIlYBDlZlOIl relates to' improvements in rap d firing guns; and the object of my inventron is to produce amachine gun of extremely simpleconstruction, which is strong and durable, 1s adapted to discharge a continuous stream of bullets, is constructed in such a way that it cannot readily get out of 'repair', is arranged to operate by water power so that when the power is turned on the gun will then work automatically, which is arranged so that it may be quickly aimed, and which is provided with a simple gear mechanism by which it may be fired in case the water power gives out.

To this end my invention consists in certain features of construction and combinations of parts, as will be hereinafter described and claimed.

Reference is to he had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views. Figure 1 is a side elevation of a gun showlng my improvements. Fig. 2 is abroken rear elevation of the gun. Fig. 3 is an enlarged detail section on the line 3- 3 in Fig. 11 and illustrates the firing mechanism. Fig. 4 is a detail elevation of one of the'spring hammers and its supporting slide. Fig. 5 is a detail view of two connected links of the cartridge belt. Fig. 6 is a similar view of a modified form of the belt. Fig. 7 is a central vertical longitudinal section through the barrel and the breech case. Fig. 8 is a cross section on the line 8 S in Fig. 7, and shows the cartridge belt and .its actuating mechanism in detail. Fig. 8 is a detail perspective view ofthe Water motor. 'Fig. 9 is a cross section on the line 9-9 in Fig. 7. -Fig. 10 is a rear elevation of the breech block; and FigQllis a section on theline 1l-11 in Fig. 3..

The gun is provided with a main revoluble cylinder 10, the length of which correspondsto the length of the gun barrels, and this cylinder at its rear enters the breech case 11 in which the firing mechanism is contained. Extending longitudinally through the cylinderlO and arranged circumferentially within it are supply in any convenient way.

are fired. In the breech case, and secured to the end of the cylinder 10, is a revoluble cog wheel or drum 12 the grooves in which serve not claimed in detail as a part of this inven- The water is delivered horizontally to tion. the wheel from the pipe 15, whichextends longitudinallyinto the center of the cylinder 10 from the front end of the cylinder and is held centrally within the same. The main cylinder turns on a collar 16 and on the discharge nozzle 17, which are provided with spokes 18 secured to the pipe 15. The waste water circulates around the barrels 11 keeps ing them 0001, and the. nozzle. projects far enough to prevent the water from running back into the barrels.

The supply pipe 15 is bent, as shown at 20, so as to extend beneath the cylinder 10 and it also extends into the lower portion of the case 11, as shown clearly in Fig. 7. The sup:- ply pipe is pivotally supported in a coupling 21, as shown in Fig. 9, and connects with 'a'.-

bent pipe 22 of a generallyrectangular shape,

which pipe forms a supporting frame and has at its lower end a nipple 23 which is journaled in the hollow supporting base 24, whichbase is connected with a suitable source of water i It will he seenthat this arrangement enables the gun to be supported so that it may be swungon its horizontal" axis, which is the coupling 21, or it may be swung on its vertical axis which is the nipple 23, and in this way it may be convenientlyandaccnratelyaimed. Thepipe 15 is provided with a suitable valve 25 which is adapted to close the inlet to the pipe as shown in Fig. 7, and this valve is provi ed with a suitable rod or stem 26 whichpro'jects outward through the back of the breech case 11, and this enables the water supply to be controlled from the-rear end of the gun.

The cartridges are supplied to the gun by ICC means of a belt 27 which is shown clearly in:

Fig. 8, and which is preferablyffermed of a B tags, 185

series or nearly semi-elliptical links 28 which are hinged together at;their edges, as shown at 29,- and the rounded portions oi which are adapted to fit snugly between the teeth of the cog wheel or drum 12. The links are shown clearly inFi-g. 5, and are provided with longitudinal bores 30in which cartridges 31 are inserted.

- If desired, the links 28 may be secured to a flexible back as, as illustrated in Fig. 6, but the form shown in Figs. 5 and '8 is preferred. a The belt, as it passes over the cog wheel,

travels-beneath aroller or buifer 32 whic h has- .e'nd trunnions 33 and theseare adapted to 1 5 grd'stin suitable supportsffl above thedrum or cog wheel 12, and-on opposite-ends of the breech case 11". v The breech case is open at the top, as. shown at, 35 in Fig. 8, to provide for the roller, and this opening is covered by .20 a swinging cap 36 which may be fastened down by thumb screws 37 or equivalent fastening; The'roller 32 acts as a buffer, as described, and v causes the beltgto be pressed downward so as 35'the b'elt27 to be turned so as to bring. the

bores of the links 28 into consecutive alignment with the barrels llof the gun, and it is obvious that the belt must; have sufficient length to permit thecar'tridges to'be inserted 4c in that portion of the belt which hangs below the case 11, whi-lethe upper cartridges are being' fired. To provide for the feed ng of the belt 27", the case 11 is provided on its sides and near the bottomwith slotsyetO through which 'thebeltextendg'and the-lower portion of the case -is bent inward to form guides'41, as shown clearly in Fig; 8, which guides are adapted to strike the inner sides of the links 28 and enable them to run smoothlyinto'the 5o grooves of the cog wheel or drum -12.

I In the breech block 13 at points' opposite the bores of the cartridge links "8 and the grooves of the cog wheel or drum 12 are cylinders or cases 42 which are screwed into the '55 breech block, as shownbest in Figs. 3 andill,

and which-are closed at their outer ends by plugs 43i and in each case or cylinder is a firing pin 44,;of substantially the usual kind, which projects through the'opposite ends of the cylindei' and is-adapted to beforced against a cartridge so as to. explode thelsame. The firing pinskt'aare each prersed normally out ward'by-aspring 515 which is held in the cylinder 42 and which presses against a collar 6 5 on the firing pin. Adjacent to'each-firing pin is an inclined tripping cam 46, these cams beinarranged.circu'mferentially, as shown is a sight 38 which may be of clearly in, Fig. 10, and ,they are adapted to actuate the spring hammers 47 so as to cause the latter to spring against the firing pins and fire the cartridges.

Each ham mer 47 is secured to aispring shank 48, and the latter is carried in a slot 49 of a block 50 which is dovetailed into the breech case 11, as shown clearly in Fig. 11, and the hammers are normally, pressed outward by thetension of their spring shanks. YVheu, however, the breech block 13 revolves it brings the inclined trippingcams 46,into successive contact with the hammers so as to depress the same, and as the cams pass over the hammers they permit the hammers to spring out and strike the firing pins.

It will be readily understood that the hammers and inclined cams maybe arranged in relation to each other so that any desired number, of hammers will be simultaneously sprung soas to strike their opposing firing pins. a

The action of the .water-wheel 14 will re-' volve the drum or cog wheeland cylinder'IO andfeed the cartridge belt under ordinary circumstances, but a hand gear is-provided so that in case the water supply gives out the cog wheel'may be turned and the gun operated by hand. To this end the breech block 13 has secured to it at the center a shaft/51, see Fig. 7, which is journaled in the back of the case 11 and which atits rear end, is provided with a beveled gear wheel 52 meshing with another gear wheel 53 which is carried by a shaft 54,see Fig. 2, and the latter is j ournaled in suitable brackets 55 on the back of the case 11, and the shaft is provided with a detachable crank 56 and by means of this crank the gear mechanism may be turned and the'cog wheel 12'revolved when necessary.

'- The'operation of the gun is as follows:-The water is turned on in the pipe 15 and as it rushes through the pipe it impinges on the water wheel 14 and so keeps the drum or cog wheel '12 and cylinder 10, turning. The waste water runs out through the nozzle 17an'd as the drum turns it carries the cartridge belt around "it and brings the cartridges opposite the firing pins Maud the barrels 11. The cartridges are thrust into the'bores of the links 28 while the latter are beneath the case 11, so that the belt may thus be kept full; As the cartridges .are carried opposite the-hammers, the inclined cams 46 tripthe hammers and throw them against the firing pins and thus the; cartridges are exploded and the bullets ejected through the barrels 11*. It will be seen that the gun will-thus automatically fire a continuous stream of bulletsso that the 0perator needs only to see that the gun is accurately' aimed, and for this reason the gun is very efiective. ,Itwill also bebbserved that there is very little mechanism about the gun which can get out of repair, and it will be-seen too that if I the water supply gives" outfthegun may be frapidly fired by hand.
