3 Claims. 1

This invention relates to gun mountings, and has for its object the provision of a gun mounting in which the operation of the gun or gun assembly is remotely controlled.

More particularly, this invention is a division of the subject matter relating te a gun mounting disclosed in my United States Patent No. 2,566,855, granted to me September 4, 1951.

Ac-cording to the invention, there is provided a gun mounting wherein pivotal movement of the gun or gun assembly is effected by power-actuated means under the influence of a pivoted member adapted upon pivotal movement to operate means arranged for movement with the gun or gun assembly about the pivotal axis thereof 'and controlling the action of said power-actuated means and by such operation cause the gun or gun assembly to follow the movement of the pivoted member, and wherein there is provided a sighting arm mounted for pivotal movement `about an axis parallel 'to the pivotal axis of the pivoted member, and mechanical means -connect- .ing the pivoted mem-ber to the sighting arm in such a manner that the pivoted member is caused to follow the pivotal movement of the sighting arm. In the case where power-actuated means are provided for effecting 4both elevationaland training movement of the gun or gun assembly, two pivoted members may lbe provided for effecting operation of such means, respectively, the two members being pivoted about the axes .of elevation and training, respectively, or a single pivoted member, arranged for pivotal -movement about the axes of elevation and training, may 'be used for effecting both movements of the gun or gun assembly. In either case, the sighting arm may be arranged for pivotal movement about axes lying parallel to the axes of elevation and training, respectively, and suitably connected to said pivoted member or members in such a manner that pivotal movement of the sighting arm about either axis produces like movement of said pivoted member or members about their corresponding axes.

By way of example, the invention will now Ibe described in greater rdetail with reference to Ithe accompanying drawings, as applied to a gun mounting in which pivotal movement of the guns is effected by oil motors in a similar manner to that described in the mentioned Pat-ent No. 2,566,855, to which reference may be made for details of the mounting not apparent yfrom this description.

In the drawings:

Figure 1 is an elevation of a twin gun mounting constructed in accor-'dance with this invention and intended for use in aircraft, and

Figure 2 is a plan view of the apparatus shown in Figure 1.

Referring *to the drawings, a pair of guns 6| are attached respectively at points 62 to a pair of recoil frames 63 in known manner. The recoil frames 63 are secured to brackets 64 extending from a common elevation member 66 rotatably mounted in a support 61. The support 67 is provided with an arcuate rack 68 arranged for engagement with a gear 69 formed on the peripheral surface of an elevation oil motor 1| (constituting the power actuated elevation means) supported in bearings 12 extending from the elevation member 66. The inner portion of the elevation motor 1| is secured in the lbearings 12 while the outer portion is free to rotate, so that, upon operation, the gear E9 is driven round the arcuate rack 68 and thus causes the elevation member 66 to rotate. The elevation oil motor 1| is controlled by an elevation valve 13 arranged for movement With the elevation member 56, and oil under pressure is supplied to the motor through the valve '|3 from a source of supply by suitable connections 14.

As in the case of the apparatus described in the Patent No. 2,566,855, mentioned above, the lower portion 82 of the support 61 constitutes the `outer portion of a training oil motor (constituting the power actuated training means) `the inner portion of which is secured to a base 83.

In this case, the valve 13 is operated through ra rod |06 by a pivoted member |07 freely mounted in bearings |08 for movement about an axis coincident with the axis of elevation of the guns, the bearings |08 being formed in brackets 54 extending from the elevati-on member 66. The pivoted member is operated through a pair of pivoted links I|2 in the manner 4described below.

The base 33 of the mounting is attached to a gun-supporting pillar |22 secured to a floor member |23 forming part of the fuselage Iof an aircraft. Secured at a position in the aircraft remote from that of the -pillar |22 is a shorter pillar |24 lying with its axis parallel to that of the pillar |22 and Iprovided at its upper end with a seat |26 for the gunner. Pivotally mounted about the axis of the pillar |24 is an operating frame |21 having a forked portion |28 extending ybehind the seat |26 and terminating in a pair of bearings |29 having a common axis disposed parallel to the axis of elevation of Ithe guns, the bearings being arranged Voperating frame |21.

extending from the baseof the pillar |2-2.

to lie at Iconvenient positions one on each side of the gunners head. Pivotally mounted in the bearings |29 is a sighting arm |3| carrying a gun sight |32 and formed with a handle portion |33 conveniently Ashaped for manipulation by the gunner and on which is mounted a firing button |34 for operating the ring mechanism of the.

guns in known manner The sighting arm |3 is provided with an extension |35passingfrom"one:

bearing |29 to the other over the gunners head, the extension being formed with a pair ,of bearings |33 which are each ccnnectedtby. aunk-|31' to an arm |38 through the medium of a ifo-:i140 extending from a forked member |39 pivoted at |4| in a bearing member |42 depending from the TheY operating; Aframe |21 thus constitutes a supporting member 'for the sighting arm I3 The forked member |39 is provided with a pair of shoes or rollers |43 arranged' to bear in an annular groove formed in a doublegrooved member |44 slidably mounted on. fthe at |41 in a bearing member |48 extendingl from the base of the pillar |24. The Orkedmember |46 is provided with a pair of shoes or rollers arranged to bea-r in the other fgroove of the double-grooved member |44 and is also provided with a pair of arms |149 Which are connected by pivoted links misto-similar arms |152 on'asimilar forkedfmember 53pivoted at |54 in a-bearing |56 The forked member |53 co-operates with a further d'ouble-grooved` member I 51- slidably mounted on the pillar |22 in a manner similar to that describedv above in -connection with ythe doublegrooved'member |44.. A further'forked'member |158 is vpivotally mounted at |59' in a bearing formed' in an arm |13 extending from a, further pivoted member |452 freely mounted'on the pillar |22. Theforkedmember |58 issimilar -in.a1l^ respects to the forked member |39, being provided withy shoes or rollers arranged'to'bear inthe second groove of the double-grooved member |531 and with arms |63'l which are-connectedto 'the pvotedmember |01' by the pivoted links M2. Thefpivotedzmember |52-is connected to the'operating frame |21 by means of a pair ofpivoted links |f64fieach connected to an arm |35 extending from theoperating frame 21 and an arm L66 extendingy 4from'the pivoted member |52. Aifurther-arm |261 extends from the Ypivoted member .|32 and is connected by-a pivoted link ||i8to the operating arm. |69. of the training valve |04Y attached to the lower portion 82 of thetraining motor.

The. dimensions of lthe various arms and links in .the mechanism connecting the sighting 'arm |.3.| and the supporting member |121 tothepivoted ymembers |91 and |52 are such as to constitute parallel Vmotion linkage movements of thesighting arm .13|- about the axis ofthe bearings |29 and about the axis of the pillar |24 thus producing similar movements of the pivoted members `|191 and |62 respectively about the axes of elevation 'and training respectively.

It will thus be'seen that as thegunner moves thesightingarm |31 about either axis the pivoted member |01 or |62, as the case may be, or both, bring about operation of the valves 13 or |04 or both, with the result that -the guns follow the `movements of the sighting arm.

The valves 1.3 and |04, which are substantially identical in construction, arethe-subject of United States Patent No. 2,455,315, to which :reference 4disposed vat'a substantial distance apart.
