MOUNT FOR GUNS.
Application filed November 12, 1926. Serial No. 148,003.
The invention described herein may be manufacturedand used by or for the Government for governmental purposes without the payment to us ot any royalty thereon.
rIliis invention relates to mounts for guns.
In the pieseiit state of development ot anti-aircraft guiinery automatic guns are employed at all ranges under three thousand yards because ot' the diiliculty in maneuverling artillery to provide for the rapid changes which suoli low positions usually involve and also on account ot' the wide variations in the functioning of fuses at these short intervals.
The mission thus assigned to the automatie guns of the .50 caliber and the 37 in/m type requires that a mount be provided which is capable of rapid elevation, which is arranged Yfor convenience otoperation and which possesses stability in all firing positions.
Certain mounts which have been arranged for convenience in operation by employing` an elevating device consisting of a system of levers lack rapidity of elevation and also stability. These mounts raise the gun bod ily while rotating it about its axis so that the actuating movement required to elevate the gun a given amount is greater than would be required if the gun turned on a fixed axis. Such bodily elevation of the gun coupled with an abnormal reduction in the base of the support entails so great a sacriiice in ,stability that the mount does not function properly at elevations above 450.
In the present invention the elevating mechanism likewise consists of a system oi levers to obtain a shifting axis of rotation but the arrangement has been altered to maintain a substantially fixed base at all elevations, to reduce the actuating movement below that required on a fixed axis ot' rotation, to provide the lowest possible mounting` 'for all angular positions of the gun7 to tix the point of application of the thrust to the mount and to associate an equilibrator with one of t-lie levers of tlie system.
Vith the lforegoing and other objects in view, our invention resides in the novel arrangement aud combination of parts and in tliedetails of `construction hereinafter described and claimed, it being understood (GRANTED UNDER THE ACT OF MARCH 3, 1883, AS AMENDED APRIL 30, 1928; 370 0. G. 757.)
partly in section ot a mount constructed in accordance with the invention and showing the position oi' the parts at zero elevation.

Fig. 3 is a diagrammatic view indicating the position of the parts at varying elevations.

Fig. 15 is a side view of the front lever; l
Fig. 1,6 is a sectional view on the line 16d 16 of Fig. 14.
Referring to the drawings by numerals of reference:
The mount comprises a bottom carriage` 11 which is shown as being secured to the nular trackway 14 for rotatably mounting a support or top carriage 15 which carries training gear 16 engageable with a fixed' gear ring 17 on the bottom carriage.
Flic top carriage is :toi-med. with a pair of .lOO
spaced up-rights 18 and a horizontally extended arm 19 and these elements mount an elevating mechanism constituted by a system oflevers which according to their position and the characteristics of the gun to be mounted may consist of single members or pairs of members. The gun is connected to this system of levers at two points both of which are preferably in rear of the center' of gravity of the tipping parts indicated at 20.
The rear connection of the gun to the carriage is had by means of a depending lever 21 pivoted to the up-right 18 and to the bottom portion of the gun at a point 22 which is located in such a manner that the movement of the lever on initial elevation of the gun from the horizontal position is on a descending arc. Because of interference with the feed mechanism of the particular gun shown, only one lever is employed.
The front connection of the gun to the carriage is effected by means of the lever 23 pivoted to the gun on the center line of bore and to a nut '24 which is movable along a screw 25 mounted on the extremity of the arm 19 and characterized principally by its position of inclination in the general direction of the elevating movement.
The third member completing the system consists of a bell crank lever 26 pivoted to the front lever 23 at a point 27 intermediate its ends and forwardly of the center of gravity 2O of the tipping parts and pivoted tothe upright 18 at a point 28. Inasmuch as the lever 26 serves to transmit the thrust of the gun to the mount, its angular position with respect to the horizontal plane of the top carriage is to be kept at a minimum. Further considerations of compactness, low mounting, the inclination of the screw 25 and t-he proper functioning of t-he levers determine the position of the point 28 which according to the present arrangement when the gun is at zero elevation is included in a perpendicular plane passing through the pivotal attachment of the rear lever 21 to the up-right.
The short arm of the bell crank lever'is utilized for connection with a horizontally disposed equilibrating device herein 'shown as consisting of a spring actuated piston 29 working in a cylinder 30 secured to the top carriage.
`The actuating mechanism 31 for rotating the screw 25 and causing the nut 24 to travel up the guide-ways 32 is positioned for the convenience of the operator who is to sight through a telescope (not shown) fixed to the gun in the vicinity of the axis of its rotation.
It will be noted from an inspection of Fig. 3 which shows the positions numbered 1 to 10 of the links as resultants of the advance of the nut on the elevating screw in increments of 2 inches, that their regular curve al?? defined by the pivotal attachment of the front lever? and the gun during movement from OO to 8OO elevation results in abnormal angular displacement of the rear lever and consequent elevation of the rear end of the gun indicated on the general line cd. rI`his arrangement provides a low mounting with sufficient clearance at all elevations.
1t will also be apparent that the reaction of the rear lever in drawing the breech end of the gun forward combined with the gain in elevation by reason of employing an inclined screw considerably reduces the actuating movement necessary t-o elevate the gun and thereby permits rapid maneuvering of the piece.
The particular gun for which the present mount is designed and which is outlined in the drawing is a 37 -m/m gun in which the recoiling members move within the receiver which constitutes the cradle. The type of gun will also indicate the feasibility or convenience of mounting the levers singly or in pairs. Y
