According to a feature of the intention the lower part of the turret comprises a rear-aligns plat forrn to receive stimulants bdis' and 661inected to the upfir" pa t of the turret by a pair" ofp llars at the front of the plasma and a single pillar at one rear corner" of; the nations so as to rears" one side and the rear open for accessto th'e wire i h saturates to a Fthef feature of the interitiori there is provided; on either sid of the turfret'" a bracket to sfiiiiioft a g'iifi of guns which (o1. sis-5a brackets are pivotedat their outer sides on the upper part of the turret and there is also pro vlded a torque rod or tube interconnecting the two brackets so that they move together and arc-shaped to conforn'r" closely to the circular contour or wall of the upper part of the turret. The sight is mounted on the centre of this torque tube,- thus dispensing with any driving linkage aridavoiding relative backlash between guns and sight:

The diameter of the upper portion oiihe turret (that is ofthe cupola and its supporting structure) is such that suificient space is pro- I vided between the guns to accommodate the head anid shoulders f t h;e is c'le'arh'l" shown in Figure 1.
were the vriiesi series fab "r S's-d" bracket extends upwardly in the outer side of its cannon and carries a bearing It by which the bracket is pivoted to the turret structure. The bearing I8 is carried by an upright l9 which is secured to a rotating ring 29. The brackets I are connected by a shallow U-outline torque tube 2| which extends between said brackets closely adjacent the inner wall of the cupola 12 as shown in Figure 1.
It will be appreciated that since the majority of the parts of the turret described above lie within the cupola they will be disposed above the fuselage of the aricraft. The cupola l2 and the cannons 53 are mounted for rotation upon the ring 29, a suitable bearing 22 (Figure 4) being provided to support said ring from a structure 23 secured to the fuselage. Attached to the ring 29 and depending from it is a skirt 24 which The lower part of the turret comprises a substantially rectangular platform 25 (Figure 1) which is connected to the skirt 24 by two pillars 26 (Figures 1 and 3) at the front edge of said platform and a pillar 2'! (Figures '1 and 2) closely adjacent the rear edge of said platform. The length dimension of the platform 25 is parallel to the axes of the cannon and is nearly equal to the diameter of the skirt 24. The width of the platform is sufficient to accommodate two ammunition boxes 28 (Figure 2) which are arranged side by side upon the platform. The gunners seat 29 is arranged upon the platform 25 with sufficient clearance for the ammunition boxes to pass beneath it and is supported by means of a pair of tie-rods 30 which extend from bracket 3! upwardly and outwardly to a sheet of armour plating 32 to which they are attached. The bracket 3! is carried by a frame 13! which lies between the ammunition boxes 28 and is supported by the platform 25. The seat is carried by tubes 33 which are pivoted at 34 to said rods 39, the position of the seat being adjusted by means of a ratchet 35 supported by the frame ML The skirt 24 is cut away. as at 36immediately over the rear corner of the platform 25 which is unsupported bya pillar from the skirt.
-The disposition of the pillars 2B, 21 in conjunction with the cut away portion of the skirt 24 enables the gunner to-enter the turret. To do this he inserts his head and shoulders through the rear end of the turret beneath the cut away portion of the skirt and then brings one leg over the ammunition boxes and the seat so that it lies on the side of the ammunition boxes which is adjacent the pillar 21. He then draws his other so that they are inseparable but so that they can move relatively to each other. The construction is such as to permit the guideway to be twisted about its long axis and also to be independently curved over its length. Each guideway 31 at its point of attachment to its ammunition box is such that the ammunition belt leaves the box in a plane transverse to the axis of the cannon and between the pilots legs. Both guideways 31 are twisted through 90 so that the ammunition belts before reaching the cannon will lie parallel to the axis of the cannon. Each beltpasses from its associated guideway 31 into a feed-assistor device 38. This device is immediately brought into operation when the guns are fired to draw the belt of ammunition from the ammunition box and through guideway 31 and to deliver it towards the cannon. In this way the excessive loads which would otherwise be imposed upon the feed mechanism of the cannon are taken by the device 33 and the feed mechanism of the cannon operates under lightly loaded conditions. The ammunition belts from the feed-assistor 38 pass through a guide 39 which directs the ammunition belt towards the cannon (see Figure 2).
Each cannon I3 ejects the spent ammunition and the broken ammunition belt downwardly through chutes 49 and 54 (Figures 3) and into a collapsible container 4! which is-supported on' together and the other is shown in the collapsed position. In order that the gunner may have'access to the turret it is necessary that the container M which lies on the rear side of the platform as shown in chain dotted lines in Fig. 1
at which he enters the turret is collapsed as described above.
It will be appreciated from the foregoing description that the lower part of the turret is only of sufficient width to accommodate the gunner and that the ammunition boxes 28 are accommodated within this width. Accordingly when the turret is rotated so that the cannon lie parallel to the longitudinal axis of the fuselage; the plat form does not interfere with the movement of the crew along the fuselage on either side of the leg into the turret so that it lies on the opposite side of the ammunition boxes. upon the ammunition boxes with his legs on either side of them and his'head and shoulders between the cannon. The 'entry' of the gunner is only made possible bythe particular arrangement of support for the-lower platform described above in'which one side and'the rear ofthe platform are unobstructed by a rear pillar.
'The ammunition belts pass'out of the boxes 28 and into a flexible guideway 31.
He is then seated The latter: isbuiltup from'a plurality of separate elements of rectangular outline which are joined together the platform 25.
turret, In certain cases it may be found desirable to collapse the spent ammuntion containers 4i in order more easily to permit movement of the crew past the turret.
The containers 4| are detachable from the lower portion of the turret and in this way they The mechanism for traversing the turret and elevating the cannon is arranged over'the front end of the platform (that is beneath the arc-f shaped torque tube 2|) and within the width of March 20, 1943, now Patent No. 2,464,654 dated v The traversing and elevating mechanism is 'of the kind described in United States patent application Serial No. 479,947 filed arch 15, 1949, and comprises'a separate elec acreage tric motor forieaoh movement and. a motor-generator set. The motor-generator set 42 is arranged: horizontally below platform 25 (Figures 2 and fi) whilst the two motors 41 and 51 are arranged with their axes vertical one on either side of the pillars 26 (Figure 3) The traversing motor 43 drives through a reduction gearing contained-within a housing 44, a gear wheel 45 which meshes with a fixed gear ring 46 (Figure 4) formed integral with the structure 23. The ele- I vating motor 4''? drives through a reduction gearing disposed within a housing 48 an elevating screw 49 co-operating with a nut 50 pivoted on a: bracket151i carried by the torque tube 2|.
Thecut-out gear 56 for interrupting the fire of the cannon when the latter are brought to bear upon a part of the aircraft structure, is disposed between the pillars 26 over the front end of the platform.
The sighting apparatus 5| is carried centrally between the cannon by the torque tube 2| within the cupola l2. The control handle 52 by which the traverse of the turret and the elevation and firing of the guns is controlled is located above the ammunition boxes and between the guide channels 3'! so as to be in a position convenient to the gunner.
The electric supply to the turret is effected through slip rings mounted centrally of the turret on the platform within a housing 53.
It will be seen that the present invention provides a gun turret which can be rotated, the only external connections being the leads for supplying electric power to the motor-generator set 42, and which, while being of sufficient size to accommodate two cannon, causes the minimum of obstruction within the fuselage and in particular allows the crew to move along the fuselage when the gun turret is rotated so that the cannon point fore-and-aft of the aircraft.
