ARTHUR TREVORDAWSON AND Geenen THOMAS 'Buckner/r,- oF. WESTMINSTER, LONDON, ENGLAND, AssIGNoEs To Vromans LIMITED,Y or WEsTM'VIN'sTER, LON-y Doit,A ENGLAND.

T yi4/.ZZ whom it may concern: y p Y Be it known that we, Sir ARTHUR' Tnn'von DawsON, knight, and GEORGE THOMAS BUCK- HAM, both subjects of the King of Great Britain, residing at Vickers House, Broadway, Vestminster, in the county of London, England, have invented certain new and useful Improvements` in or Relating to Mountings for High-Angle Ordnance, of

l0 which the following is a specification.

This invention relates to gun mountings of the kind in which the gun can be elevated from horizon to horizon, that is to say through an angle of 180 degrees or more.

According to this invention we provide a rotary or stationary chamber beneath the mounting for the purpose of enabling the gun to be loaded when iiring vertically or at large angles of elevation approaching the vertical Without the necessity of depressing the gun to a convenient loading position. This chamber 'also serves to receive the empty cartridge cases when the breech of the gun is contiguous to this chamber and furthermore enables the distance of the trunnions above the deck, in the case of a naval mounting, and the distance above the ground in a garrison gun, to be reduced.

In order that the said invention may be clearly understood'and readily carried into eifect we will describe the same more fully with reference to the accompanying drawings in which Figures l and 2 are respectively a rear elevation and a side elevation illustrating in a more or less diagrammaticpmanner one constructional form of the invention, the chamber beneath the mounting being shown in section.

Fig. 3 is a View similar to Fig. 2 showing the gun elevated to an angle of ninety derees. g A is the gun, B, B are the trunnions and C, C are the carriage side cheeks.

D represents the aforesaid chamber which, in the example shown, is attached to or made integral with the carriage cheeks and is carried by a bearing D let into the deck in a naval mounting or into the base plate in the case of a garrison mountin the chamber in this case serves as the training pivot. If the chamber D be made stationary, that is unattached to the carriage cheeks, it is let Specification of Letters Patent. -V Datemi-ged Oct. 14, Application mea Apiri 13, r9i5. serial' iro. `21,1211

MOUNTING FOR HIGH-ANGLE ODDNANCEL into the deck or base plate as above stated, and the 'carriage cheeks may lthen carry a ring which is rotatably mounted at the top of the chamber. In both cases the chamber is made of substantial diameter so that a comparatively long recoil can be obtained. The chamber D may be o'f such a depth that a gunner can be accommodated therein to assist in loading the gun when the latter is approaching the maximum angle of elevation. The top part of the said chamber may be provided with a portable cover for the purpose of closing the chamber when the mounting is not in use.

lThe carriage is adapted to be trained in any suitable manner through a complete circle Vand the gun may be elevated by means of an approximately semi-circular rack A attached to the gun cradle and meshing with an elevating pinion A2 mounted in one of the carriage side cheeks.

l/Vhat we claim and desire to secure by Letters Patent of the United States is l. The combination with a high angle gun mounting, of a fixed platform by which said mounting is rotatably carried, a chamber arranged beneath said mounting and sunk beneath the level of the platform, said chamber being made of such depth that a gunner can stand therein to assist in loading the gun when at high angles of elevation.

2. The combination with a high angle gun mounting having two cheeks between which the breech end of the gun is disposed when at high angles of elevation, of a fixed platform by which said mounting is rotatably carried, a chamber arranged beneath said mounting and open to the space between the cheeks, said chamber being sunk beneath the level of the platform and being made of such depth that a gunner can stand therein to assist in loading the gun when at high angles of elevation.

3. rlhe combination with a high angle gun mounting having two cheeks between which the breech end of the gun is disposed when at high angles of elevation, of a fixed platform by which saidmounting is rotatably carried, a chamber attached to and depending from said cheeks so as to rotate therewith during training, said chamber being sunk beneath the level of the platform and being made of such depth that a gunner can stand therein to assist in loading the gun when at high angles of elevation.

4C. The combination o'f a gun adapted to be red substantially vertically, odia pair of cheeks receiving the trunnions of the gun and upon which the gun may be turned on a horizontal aXis to elevate and depress it, and a chamber located below the space between the cheeks and open at its upper end, said chamber providing unobstructed space below the breech of the gun When the gun is elevated or depressed, permitting loading of the 'gun by inserting a shell into the breech from the space Within the chamber While the gun remains trained substantially vertically. 15
