(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 8, 1921, 41 STAT. L, 1818.)

To all whom it may concern:

Be it known that we, EUSTAGE HnNRY TENNYSON DEYNooUR'r and FREDERICK. SxnnNs, both subjects of the King of Great Britain, residing at the Admiralty, Whitehall, in the county of London, England, have invented certain new and useful Improvements in Gun Mountings (for which we have filed application in Great Britain, No. 18,421, dated Dec. 22, 1916, Patent No. 121,746), of which the following is a specification.

This invention consists in an improved combined gun mountin and protective shield which, while capa le of being employed on any movable or stationary structure, is particularly applicable to armoured or armed cars, such as for example as those employed in overcoming heavy defence work used in trench warfare.

It has heretofore been proposed to mount a gun in a sphere which is pivoted in a step bearing to rotate about a vertical axis, and which can roll on a suitable track about a horizontal axis, the sphere being arranged to move within an aperture in a fixed shield 5 also a gun has been trunnioned in a art spherical mounting which is arrange to rotate either about a horizontal or a vertical axis in an opening in a fixed shield, the mounting being provided with an elongated aperture through whichthe barrel 0 the gun protrudes and which allows movement of the gun for training or elevating as the case may be, the mounting towards the rear being shaped so that it fits closely around the gun barrel during its movement relatively to the mounting; also it has been proposed to form or fit to a gun a ball capable of movement within asocket secured to the wall of the structure within which the 'gun is placed, the ball having a through opening for a sighting telescope.

A combined gun mounting and protective shield according to this invention is characterized by a spherically shaped shield dis posed in an aperture in the structure carrying the gun and formed with a sighting aperture and with a gun aperture closely embracing the gun, a forked member, means for pivoting the gun to said member for elevatmg and means for pivoting said member 'to the structure for train In the accompanying drawings which illustrate a construction embodyin this inyention, Figure 1 is an elevation, i re 2 is an elevation looking in the direction of the arrow in Figure 1, Figure 3 is a plan and Figure 4 a part sectional elevation of a form of shutter suitable for the construction of mounting.

In the drawings 1 is the plating or bulkhead of the vehicle or stationary structure and 2 is a plate attached to the part 1. The parts 1 and 2 are formed with holes in which the shield 13 (hereinafter described) is disposed. In the construction shown virtual trunnions are provided for the gun, which is arranged to slide into and out of position in the mounting. The gun 4 is supported in a clamping ring 11 having a clampin band 11 readily removable such as by w1thdrawal of one or both securing pins 11 according as to whether the band is pivoted or completely removable. The clamping ring is carried by a bracket 12 secured to a spherically shaped shield '13 mounted withm a gun ort or other enveloping aperture forme in the structure carrying the n, and the ring or bracket is provided wit trunnions 14 engaging in hearings in a fork 15 mounted to rotate about a vertical axis by means of a stud 15' engaging in a step or other bearing secured to the structure such as directly or indirectly to the plates 1 or 2. 'The trunnions are retained in position in the bearing by hinged or pivoted caps 15 secured in position by wing bolts 16. The shield 13 is shown in slightly exceeding the hemisphere, and is provided with a sighting aperture 17. It will thus be seen that when the gun is in position, the gun and the shield can be moved in a universal manner about the horizontal trunnion axis and about the vertical axis of the forked pivot, the line of sight through the aperture being always fixed relatively to the longitudinal axis of the By removing the clamping band 11' the form shown in Figure 4 is provided which necting the gun can be withdrawn and by removing the aperture in said structure and formed with wing bolts 16 and turning back the caps a slghti aperture and w1th a gun aperthe shield can be removed. ture close y embracing the n, a forked In order to close the opening in the shield member, a bracket on said s ield for supwhen the gun is removed a shutter in the porting the gun, means for detachably conto said bracket, means for consists of a spherically shaped portion 18 pivoting sai bracket to said member for v ofsufiicient area to cover the whole of the elevatin and means for pivoting said memaperture in the shield and is carried by a her to t e structure for training.
