The sleeves I and 8 carrying respectively truncated conical carriers It and it each provided with a-plurality-of radiating tubular receivers l2 :and I3" respectively; these tubular receivers being equidistantly spaced about the truncated'conical carriers It and H and arranged sothat-their,axes'meetithe axes of the'gun, the trunnions .andthe axis pins ina' commonpointof intersection, the carrier for the-set of receivers l2-being so related with the carrier for the receivers lite. g. after the. manner of the-teeth of a' pairof bevel gears; that consequent on simultaneous; 'step-by-step rotation of the-carriers- H3 and ll at'equal speeds such receivers-will be brought successively and alternately into co-axial alignment .with loadingtray l4 fixed to thebreech andlalso intocoaxial alignment with the-trunnions; In the-accompanying-drawings an even number of receivers is'shown on each of the=carriers Ill-and l l, but theuse-of an odd number is not excluded; The intended arrangement issuch. that I rounds to be'fired are'fedinto'the'receivers'l Zwhen these are: co-axial with the trunnions and transferred step-by-step-bythe rotation of the carrier l0 into alignment with the gun. Theyarethen loaded into the gun andrthecarriers Ill; and II rotated until-a; receiver" I3'onflthe carrier H is aligned with the gunwhichmay then be fired and the case ejected into the-receiver l3 after which a, :further step-by-step rotation of th'e'carriers land brings the receiver I3 into alignment with the trunnions when the case-isdischarged; e. g. intoa return chute l5 (see Figure l), which=canhave combined therewith at its upper end abranch chute It dischargingon to the deck or other convenient position, selection as to the point of discharge being afiorded by means of an adjustable shutterll in abridge structure across the upper end ofthe chute i 5.
The roundsare fed in succssioninto thesuccessive tubular guides-l2 of thecarrier Hi from the magazine IE -(see Figurese andfl5) or other convenient-source of supply via ahoistlll of known form anda part-arcuateguide 20 :having at its upper terminala power operatedram 2i for pushing each round: into the appropriate 7 tubular guide !2; The'feedof ammunitionalong thehoist guide I9 andrthe movements-crane ram 2| are synchronised with the movements of a chain-link type of ram 22 having an operating end co-axial with the breech and adapted to feed the round in the tubular guide l2 which is coaxial with the tray l4 into the breech, this ram 22 being operated from a motor 23 adapted to operate alternately with a motor 24 which drives both of the carriers l and H through the medium of two shafts 25 and 26 arranged with their axes at right angles to each other and provided with bevel gear wheels 21 which eii'ect the desired transmission from the motor 24 to the carriers l0 and II, by meshing with bevel gear wheels 28 and 29 respectively fixed on spindles 30 nd SI driving the carriers l0 and H through the medium of pinions 32 and annuli 33, the annuli 33 being carried by a pair of discs 34 which co-operate with another pair of discs 35 which connect the truncated conical carriers to the sleeves 5 and 8.
The motors 23 and 24 are carried by a V- shaped frame 36 which also carries the bearings for the shafts 25 and 26, this frame being provided at its ends with bearings for the sleeves 5, I and 8 about which rotate the carriers l0 and H the apex or rear-most portion of this frame being fixed to the trailing end of a stout strut 3'1 forming a cantilever projecting rearwardly from the cradle I.
Following the alignment of the appropriate receiver [2 with the breech, the rotation of the motor 24 is stopped and the motor 23 brought into operation automatically to effect the ramming of the round into the breech, the rammer 2| at the same time transferring a round from the hoist 20 to the appropriate receiver aligned with it. Immediately upon retraction of the ram 22 by the reverse drive operation of the motor 23, the motor 24 is brought into operation to align one of the tubular guides l3 of the car rier II with the breech, whereupon the round is fired the gun recoils and the empty cartridge case is ejected into the tubular guide |3 co-axial with the breech at the same time and a fired case is removed, by a mechanism hereinafter described, from the appropriate guide l3 aligned with the trunnions. The motor 24 is again brought into operation to advance the carriers l0 and I to the desired extent to align one of the tubular receivers l2 with the breech for receiving the ram 22 for ramming the round home into the breech, and another with the rammer 2| to receive a round from the hoist 20.
It will be evident that it is a simple matter to control the operation of the motors 23 and 24 so that rotation of the carriers l0 and II only take place when the ram 22 is fully retracted, and also means is provided whereby the firing mechanism is locked against operation otherwise than when one of the empty cartridge case receiving guides I3 is aligned with the breech. This latter means is not shown but may comprise equidistantly spaced segmental abutments on the carrier II which obstruct firing movement of a part of the firing mechanism.
The discharge of the empty cartridge cases from the tubular guide I3 is effected automatically by bringing into operation at the period when the rammer 22 is operating a motor 38 driving an endless chain 39 accommodated within a hood 40 mounted with the motor 38 on the appropriate side of the gun breech, this hood 4!! together with the motor 38 being carried upon a segmental plate 4| fixed to a squared extension 2a of the trunnion 2, the segment 4| being guided in a segmental channel or angle plate 42 fixed to the trunnion bracket 43. The endless chain 39 carries a plurality of fingers 44 adapted to travel along longitudinal slots |3a provided in the guide tubes l3 so as to eject theempty cartridge cases into the chute It.
It will be evident from the foregoing that the present invention provides means for automatically feeding rounds to and discharging cartridge cases from a gun for any position of elevation and affording a wide angle of movement in the elevating direction. It will be evident that the axes of the receivers l2 and I3 will always traverse a path intersecting the axis of the trunnions and also that of the gun, and that the correct alignment of the receivers with either trunnion or gun depends solely on the appropriate increment of rotation being given to the carriers l0 and and not at all to the elevation of the sun.
In order to ensure that these operations take place in their correct sequence suitable interlocking devices may be provided.
To enable a high rate of fire to be maintained the hoist l9 has located adjacent its lower end a rotary or endless conveyor platform 41 embodying round receiving tubular guides 45 brought successively over a feeder 46 which process the rounds into the hoist in known manner.
It will be appreciated that only one rotary carrier need be employed, e. g. for loading the gun and if desired receiving in each receiver tube an empty case following the delivery from the appropriate empty receiver tube of the live round into the'breech. Alternatively the single rotary carrier can act merely to receive spent cases.
It will be understood that the present invention is intended for use with guns of the larger medium or like type, as of course with light cannon or heavy machine guns the customary chainlink or replaceable magazine would be employed.
