This invention relates to gun turrets of the type in which a gun or gun assembly is pivotally mounted about an axis of elevation on a gunsupporting platform which is rotatably mounted on a stationary support for movement about a training axis and in which power-actuated train- 7 ing and elevating means are provided.
' elevation of the gun or gun assembly and adapted upon pivotal movement about such axes to operate respectively means arranged for movement in synchronism with the gun-supporting platform and controlling the action of said training means and means arranged for movement in synchron sm with the gun or gun assembly about its axis of elevation and controlling said elevating means, such operation causing the gun or gun assembly to rotate about the training axis and axis of elevation respectively in the same direction as the sighting arm through an angle substantially equal to the angle or rotation of the sighting arm. The power-actuated training and elevating means are conveniently in the form of hydraulic motors and the controlling means for the training and elevating means are in the form of hydraulic valves.
The invention is particularly useful in its application to aircraft armament and by way of example, such an application will now be described in greater detail with reference to the accompanying diagrammatic drawings, in which Figures 1 and 2 are side and front elevations, respectively, of a gun turret constructed in accordance with the invention, for use in aircraft.
Referring to Figures 1 and 2, a pair of guns I! are mounted for pivotal movement about an axis of elevation in a pair of bearing members I2 secured to a platform l3 which is rotatably mounted on a stationary annulus 15 secured in the tail of the fuselage M of an aircraft, the axis of rotation of the platform being the common training axis of the guns I l. The guns H are mounted in carriers 16 which are provided with suitable recoil mechanism and are attached to the ends of a common supporting member I! on which is mounted the inner portions of a pair of oil motors housed in bearings [8 formed part of the bearing members I 2. A single elevating valve !9 controls both elevating motors by supplying fluid to both motors simultaneously, the valve 1 9 being attached to one of the gun carriers 46 and suitably connected to the motors. Operation of the valve I9 is brought about by movement of a valve-operating arm 2! which is connected by a pivoted link 22 to an actuating member constituted by an operating frame 23 freely mounted about the common axis of elevation of the guns 5!. The operating frame 23 is connected at 25 by means of a pivoted link 24 to one arm 25 of a two-armed lever 26, 2! pivoted at 28 in a bearing 29 secured to the rotatable platform l3, the arm 21 being connected by a pivoted operating link 3! to an arm 32 projecting from a sighting arm 33 carrying a gun sight 35, suitably harmonized with the guns H, and formed with a handle portion conveniently shaped for manipulation by the gunner and on which is mounted a firing button for electrically operating the fir ing mechanism of the guns in known manner. The arm 2? of the pivoted lever 26, 27! together with the link 3! and the arm 32 constitutes a parallel motion linkage connecting the sighting arm 33 to the pivoted lever 26, 2?. The arm 25 of the pivoted member 26, 27 together with the link 24 and the efiective arm of the frame 23 which extends from the pivot 25 to the axis of elevation constitutes a further parallel motion linkage connecting the pivoted lever 26, 2? to the frame 23. The sighting arm 33 is mounted in a pair of bearings 34 formed in an operating member 36 pivotally mounted in the main framework of the turret for rotation about an axis coincident With the training axis of the guns 5 l. The operating member 36 is formed with an arm 3'! which is connected by means of a pivoted link 38 to the valve-operating arm 39 of a training valve 4! attached to a bracket 62 extending from the main framework of the turret. The valve 4! is suitably connected to a training motor 43 attached to the rotatable platform E3. The motor 43 drives the rotatable platform It by means of a pinion A l engaging a suitable gear on the stationary annulus l5.
It will be seen that pivotal movement of the operating member as by means of the sighting arm 33 causes the arm 37 of the operating member 36 to operate the valve ll which, in turn, causes the oil motor 53 to drive the platform l3, while movement of the sighting arm 33 about its 3 axis parallel to the axis of elevation brings about operation of the valve I9 through the link 3| and associated mechanism, thus causing the elevation motors to elevate or depress the guns II in accordance with the direction of movement of the sighting arm 33.
The construction of the valves 4| and I9 is such that operation of the oil motors is substantially instantaneous upon operation of the valves so that the guns are caused to move substantially simultaneously with the sighting arm.
The construction of the valves 19 and 4| is the subject of United States Letters Patent No. 2,455,315, to which reference may be made for any details of construction and operation not apparent from this description.
The gunner normally sits on a seat 46 provided on the platform 13 and thus rotates with the platform during training movement of the guns, and under such conditions come gunners find it difficult to control the sensitive movement of the sighting arm 33 accurately, presumably as a consequence of their movement with the platform 3. It i found that this difficulty is avoided when the gunner is able to place his feet on some part of the aircraft that is stationary relative to the aircraft. Accordingly, the platform [3 is provided with an aperture giving access to a floor member 47 of the aircraft so that the gunner may put his feet on such member while manipulating the sighting arm. Suitable guides are provided on the sides of the aperture so that if the gunner does not move his feet on the floor member 4'! in accordance with the movement of the platform It the appropriate guide will do so until such time as the gunner finds it necessary to take up another position.
