6 Claims.
The invention relates to gun turrets, and particularly to power operated turrets.
One object of the invention is to provide a power operated gun turret having two guns and a large ammunition space, which is so arranged as to be very compact and thus to require relatively little space.
Another object of the invention is to provide a gun mounting for a turret which permits movement and aiming of the gun through a very substantial angle without movement either of the turret or of the body of the gunner. More particularly, this part of the invention contemplates the mounting of a sight, and its connection to the gun, in such a manner that it moves about an axis which passes through the neck of a gunner within the turret, so that by merely tilting his head he can follow the sight.
Still another object of the invention is to provide an arrangement which permits the carrying within the turret of a large quantity of ammunition.
An additional object of the invention is to provide, in a turret which turns in azimuth and in which the gun turns in elevation, an ammunition supply carried by the turret and a iiexible feed mechanism of simple construction for feeding ammunition from the supply to the guns whatever may be the elevation of the guns.
Still another object of the invention is to produce a simple and effective control for a turret.
Further objects and advantages of the inven- `tion will appear more fully from the following description particularly when taken in conjunction with the accompanying drawings which form a part thereof.
In the drawings:
Fig. 1 shows in side elevation a turret embodying the invention;
Fig. 2 is a top plan view thereof; and
Fig. 3 is a fragmentary front elevation thereof.
Fig. 4 is a diagrammatic perspective view, showing the principal elements and their relationship, particularly the mounting of the guns and gun sight.
The turret includes a ring member 2 carrying rollers 4 which run on a track `E carried by a vehicle 8. 'Ihe turret body Ill is dome-shaped, and is preferably formed of a transparent material. This dome extends out of the vehicle. It is provided With two parallel slots to I-permit movement of the guns I2. At one side of the turret is a downwardly extending curved sheet I4 of metal, shaped to provide a back and sides for a seat. The seat bottom I6 is hinged at I8 and is held in place by a suitable catch 20. This provides a space by which the gunner can stand in firing` position if desired, and also gives an easy means of entrance and exit to and from the turret. The seat is reinforced by tubes 122 of metal extending downward from ring 2.
At the opposite side, the ring 2 has a downward shield portion 24 of armor plate. This supports a foot rest 2B and an ammunition box 28. Upstanding from opposite sides of the ring are ears, supports or frame portions 30, for the guns. A plate 32 extends inwardly from the ring 2 on the side opposite the seat I6.
The guns i2 are mounted on pivots 34 between ears 3D and uprights 36 carried by plate 32. The butts of the guns are arranged on opposite sides of seat It, so that the gunner actually sits between the guns. Each gun is carried by a frame 38, which engages pivots 34, through a suitable adjusting mechanism 40 so that the elevation and azimuth angles of the gun with respect to the frame can be varied.
It will be noted that the axes of pivots 44 for the U-shaped frame pass substantially through the neck of a gunner seated on seat i6. Thus the. gunner is able, by merely tilting his head, to iollow the sight at all times. This of course reduces the space necessary for the operation of the guns.
'Ihe guns are elevated by a suitable electrical mechanism. For example, gun frames 38 are provided with rigid gear segments 62. These mesh with gears 64 on a shaft 56 carried on uprights 68 from plate 32. Shaft G6 is driven through gear 10 by a gear 12 on a small shaft 14. Shaft 14 in turn .is driven through gear l5" by a worm 18 on the shaft of motor 8D, carried by plate 32.
A second motor 82 is provided for rotating `the turret. Its shaft carriesagear 84 which meshes' at an angle with gear 86 on shaft 88. A gear 90 on shaft 88 meshes with a rack 92 xed in the vehicle.
Motor 8U is controlled by a rheostat 94 having a depending operating lever 96 pivoted about a horizontal axis at 98. On this lever is mounted a rheostat for controlling motor 82. The shaft |02 is turnable about a vertical axis to control this rheostat by spaced handles IEM on a cross bar |06. With this arrangement, the gunner can change the guns in azimuth by turning shaft |02, and in elevation by rocking lever 96. Of course, stick triggers |08 are provided on handles |04. Also provided on the left hand handle H34 is a master switch |5 called the dead-man switch, which is operated by the heel of the hand in the same manner as the safety bar on an automatic pistol. If this switch is not closed by pressure of the hand, the turret cannot be operated. Convenient to the thumb of the right hand on cross bar It@ is mounted a high-speed button` |501 which, when depressed, multiplies the speed of the turret and gun moving means for both azimuth and elevation'.
In' the usual machine gun, the magazine which holds the ammuni'tion for ther gun is rigid with the gun. This requires either a large structure to hold" a great quantity of shells, or frequent changing or reloading of the magazine. Neither of `these is practical in a small turret. The present invention therefore utilizes large, fixed ammunition boxes '28?, with arrangements for. feeding the guns therefroml at varying elevations. These consist of tube H0 of rectangular cross section extending from boxes 28, and serving as guides for cartridges |f|2 carried by links H4. The mouth |^|B` of each tube ||0 is spaced from the gun at a point opposite thereceiving slot ||8A in the breech block, andV slightly 'to the rear of the slot. The mouth |||54 4is arranged so that, at anY intermediate .position of the gun inv its angular movement in elevation, that is, :between the.
solid line and broken line positions in Fig. 1, slot III-Sand mouth lil-6 are parallel. In other Words, mouth |`|f6` forms an angle with slot ||8 which is alwaysless than the possible angular movement of the gun, and preferably does not exceed about half of such possible movement, being positioned so that a line parallel to its longitudinal axis substantially bisects the angular elevation range. Because of the space between mouth IIB and' slot ||8, the belt can twist to a degree suiicient to" permit proper: feedingv to the gun` atl alll times.
Ears 30- are shaped to provide discharge channels for .the gun-s. 'I'.hese ears are hollow, and have openings in.` their inner walls opposite the ejector to receive spent cartridge cases and links. Inasmuch as ejected cases are discharged from the'l bottom of the gun, a chute ||9` is built into frame 3-8 which changes` the direction of travel of the ejected cases so that the case-s then travel toward! ears 310.. With the interior of. these ears, the discharge spout-s1 |20' communicate, to conduct the ecases and links to a point of discharge.
AWhile we' have described herein. one embodiment of our! invention, we wish it to be understood that we dov not intend. tolimit ourselves thereby except .within the scope of lthe vappended claims.
