MULTIPLE GUN.

Application filed March 27, 1918.

and Improved Multiple Gun, of which the following is a full, clear, and exact description.

The invention relates to ordnance, and its object is to provide a new and improved multiple gun more especially designed for use on aeroplanes or marine vessels or for use in the field against aeroplanes, infantry, cavalry and other bodies and arranged to permit of firing bullets in a tubular or a conical path. Another object is to provide a single trigger actuating mechanism for simultaneously actuating the triggers of several machine guns to fire the latter in unison. Another object is to provide a single sighting means for the several machine guns.

In order to produce the desired result, use is made of a plurality of machine guns adjustably mounted on a carrier and arranged to allow of adjusting the machine guns one relative to the other, thesaid machine guns in one position having their axes parallel and in another position convergent. Use is also made of a sighting tube forming the carrier for a plurality of machine guns grouped around the said sighting tube, the latter providing a single sight for the several machine guns. Use is also made of'a trigger actuating mechanism connected with the triggers of the several machine guns to fire the latter in unison.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

A tripod or other suitable support 10 is provided with bearings 11 in which is mounted to turn a carrier 12 in the form of a sighting tube held against longitudinal movement in the bearings 11 by collars 13 secured to the carrier and abutting against the outer faces of the bearings 11. The-carrier 12 is provided with cross hairs 14 (see Fig. 4) to permit the operator to obtain an accurate sight, as hereinafter more fully explained. Around the carrier 12 is grouped a series of machine guns 20, 21 and 22, of any approved construction, the machine guns and 21 being preferably located on opposite sides of the carrier 12 while the ma-' chine gun 22 is arranged above the carrier 12, but the several guns are preferably spaced equal distances apart from the axis of the carrier 12. The breech ends of the side machine guns 20 and 21 are mounted to swing on vertical pivots 23 and 24 held on a bracket 25 attached to the rear end of the carrier 12. The breech end of the top machine gun 22 is connected by a transverse pivot 26 with the bracket 25, and by this pivotal arrangement of the three machine guns the latter can be swung from normal parallel position toward the carrier 12 into converging position. The muzzle ends of the three machine guns 2(), 21 and 22 are provided with collars 30, 31, 32 pivotally connected by links 33, 34 and 35 with a tubular slide or sleeve 36 mounted to slide backward and forward on the forward end of the carrier 12. The slide 36 normally abuts against a collar 37 attached to the forward end of the carrier 12, and the rear edge of the slide 36 is pressed on by a spring 38 abutting against a carrier 39 adjustably secured by a set screw 40 to the carrier 12, to permit of adjusting the tension of the spring 38. It is understood that the spring 38 normally holds the slide 36 against the collar 37, and when the slide is in this position then the links 33, 34 and 35 extend radially in a transverse plane and hold 'the machine guns 20, 21 and 22 in parallel position one relative to the other and to the carrier 12. When the slide 36 is moved rearwardly against the tension of the spring 38 then the links 33, 34, 35 swing the several guns into inclined or converging position relative to each other and to the carrier 12, as will be readily understood by reference to the dotted line positions shown in Figs. 1 and 2, and the full line position shown in Fig. 7. It is understood that when the machine guns 20, 21 and 22 are in parallel position and are fired then their bullets travel in a tubular path but when the machine guns are moved in converging position then the bullets fired by the machine guns cross each other (see 'Fig. 7) a distance beyond the muzzle ends of the machine guns and made to travel in two conical paths, the apexes of which coincide, as will be readily understood by reference to Fig. 7. It will be noticed that the bullets are scattered and hence readily strike a distant target sighted with the sighting tube formed by the carrier-l2 and whether such target is an aeroplane, infantry, cavalry or other body.

In order to still further vary the path of the bullets, the tubular carrier 12 and with it the guns 20,. 21 and 22 may be turned during the firing while simultaneously swinging the guns from the parallel to the convergent position thus producing the effect illustrated in Fig. 8.

In order to enable the operator to actuate the slide 36 the following arrangement is made: To the sides of the slide 36 are secured rearwardly extending rods 50 connected with each other at their rear end by a crossbar 51 to which is secured a chain, cable or other flexible connection 52 passing over a guide pulley 53 mounted on a bracket 54 attached to the carrier 12. The rear end of the flexible connection 52 is attached to an arm 55 held on the lower end of a rod 56 depending from-a sleeve 57 secured by a set screw 58 or other fastening device to a crossbar 60 extending below the bracket 25. The ends of the crossbar 60 are formed into pivots 61, 62 journaled in lugs 63, 64 depending from the bracket 25. To the pivots '61, 62 are secured the upper ends of handles 65 and 66- provided with grips 67 and 68 mounted to turn on the handles 65 and 66. Normally the handles 65 and 66 hang down vertically, as shown in Fig. 5, and when it is desired to tilt the machine guns 20, 21 and 22 then the operator takes hold of the grips 67 and 68 and swings the handles 65 and 66 rearwardly thus turning the crossbar 60 and causing the rod 56 and its arm 55 to exert a rearward pull on the flexible connection 52 whereby the sleeve 36 is drawn rearwardly and the guns 20, 2'1 and 22 are swung into converging position, as before explained. When the operator releases the grips 67 and 68 then the spring 38 returns the slide 36 to forward position thus swinging the guns 20, 21 and 22 back into parallel position. The return movement of the slide also causes a return movement of the handles 65, 66. When it is desired to turn the carrier 12 in its bearings 11 then the operator taking hold of the grips 67, 68 pushes the same sidewise, thus causing the carrier to turn in its bearings, as will be readily understood by reference to Fig. 9.

The trigger mechanisms 70 of the several machine guns 20, 21 and 22 are simultaneously actuated by a trigger actuating mechanism controlled by the operator having hold of the handle grips 67, 68. For the purpose mentioned use is made of a sleeve 71 mounted to slide on the carrier 12 and having three arms 72 engaging the trigger mechanisms 70 of the several machine guns 20, 21 and 22, as plainly indicated in Figs. 1 and 6. To the sleeve 71 is secured one end of a chain or other flexible connection which passes over a guide pulley 81 journaled at the front face of the bracket 25, and the said flexible connection extends downward from the guide pulley 8]. and then passes around a guide pulley 82 journaled in a bracket 83 (see Figs. 1 and 5) attached to the crossbar 60. The flexible connection 80 next passes around a guide pulley 84 journaled on the rod 56 and the end of the flexible connection 80 is attached to an arm 85 secured to the top of the grip 68 so that when the latter is turned at the handle 66 then a pull is exerted on the flexible connection 80 whereby the caused to slide rearward on the carrier 12. This rearward movement of the sleeve 71 causes its arms 72 simultaneously to actuate the trigger mechanisms 70 of the several guns 20, 21 and 22 to fire the same in unison.

From the foregoing it will be seen that by the arrangement described, the operator in charge of the multiple machine gun can sight a distant object through the carrier which forms a tubular sight and as the several guns 20, 21 and 22 are grouped around this sighting tube, it is evident that the latter forms, a common sight for the several guns. It will further be noticed that the operator in charge can readily swing the guns from parallel to converging osition, can turn the carrier in its bearings and with it the guns, and at the same time the operator can fire the guns by corre spondingly turning the grip 68 as previously explained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent r 1.
