GUN MOUNTING Filed Nov. 13, 1940 fire 2 n Patented Apr. 25, 1944 UNITED STATES PATENT orF1cE-' f Archibald Goodman Frazer-Nash, Tolworth, England Application November 13, 1940, Serial No. 365,517
- In Great Britain April 4, 1939 I 2 Claims.
This invention relates to gun mountings and more particularly mountingsfor machine and other relatively light guns, inaircraft and other vehicles of the kind in which there is provided means whereby in positioning the gun with respect to its mounting the gun may be moved in a vertical and lateral direction and locked in the position in which it has been so adjusted, the means in question including amain bracket or element adapted to .be secured tovthe mountin for the gun and associated with the main bracket a gun bracket with which the gun may be directly connected, and having a screw-threaded element adapted to be rotated for effecting movement in a vertical direction between the gun bracket and the main bracket, the gun bracket being preferably in the form of a stirrup or U-shaped member with which the gun may be engaged by a pin extending through holes in its limbs.
In one construction of this kind it has been proposed to use a single locking means for locking the gun against displacement laterally as well as vertically.
The object of the invention is to provide an improved gun mounting of the kind first above specified in which for effecting motion of the bracket in a lateral direction there is provided a cam r eccentric adapted to be rotated about the axis of rotation of the screw-threaded element whereby motion is imparted to the gun bracket in a vertical direction.
According to the invention, for locking the gun against displacement laterally as well as vertically, there is provided a lock nut rotatable about the same axis as that of the screw-threaded element for efiecting movement between the gun bracket and the main bracket in a vertical direc tion.
The invention will be described further in detail and by way of example with reference to the accompanying drawing, in which:
Figure 1 is a view in elevation of one construction of a device in accordance with the invention;
Figure 2 is a plan view;
Figure 3 being a sectional elevation thereof on a plane indicated by the line 3-3 of Figure 1;
Figure 4 is a perspective view of a part of the gun mounting detached and as seen from below, a portion of the related threaded member being also shown.
The gun bracket 1 in the form of a stirrup has in its base an elongated slot 2 the major axis of which extends in the direction of the axis of the pin by which the gun cradle is connected with the stirrup and which will be engaged in the holes 3 provided in the horns of the stirrup.
The stem 4 of a screw-threaded member 5 passes through the slot 2 and a polygonal head ii on the stem is slidably and non-rotatabiy mounted in a slot l provided in the underside'of a retaining plate'l. The slots 2 and 1 are parallel and the plate I is secured in position by screws '1 passing through the plate and threaded in the bracket I. One'edge of the-plate "i is turned downwardly to form a stop l The lower surface of the stirrup is provided with lips or ribs 8 in which is slidably engaged a rectangular block 9 furnished eccentrically with a hole in which is engaged an eccentric Hi carried by a block Ill. The block l0 furnished with a thumb piece ll whereby it may be rotated about the stem of the screw-threaded member above referred to in either direction from the position shown in full lines in Fig. 2, the right hand position of the thumb piece ll being shown by dotted lines in this figure. Rotation of the eccentric Iii imparts a traversing motion to the gun bracket, being limited in its extreme positions by engagement of the block 9 with the stop l Such traversing movement of the gun bracket with relation to the member 4 is permitted by the engagement of said member 4 and the head 6 in the slots 2 and 1, respectively.
On the stem of the screw-threaded member and below the eccentric is located a bush l2 which is externally screw-threaded and is connected with said screw threaded stem by a pin and slot [2 The bush I2 is engaged by a nut i3 furnished with a milled head It to facilitate its rotation, this nut being arranged to bear upon a flange i5 formed on a sleeve l6 engaged within a bush I'l formed of relatively flexible material which, together with a similar bush i8, is engaged in a hole in the main bracket l9.
Rotation of the nut I3 moves the screwthreaded member 5 and thus the gun bracket i in a vertical direction, the member 5 being held against rotation by the polygonal head 6 engaging in the slot 1 and the bush l2 being prevented from turning by the pin and slot connection I2.
To lock the gun bracket in any position into which it may so have been adjusted, a further nut 20 is engaged with the screw-threaded member 5 and to prevent this nut becoming detached therefrom, on the spindle there is secured a washer 2| which is held in position by means of a retaining ring 22.
Where, as is usual, the gun mounting is arranged so that the gun is supported at a forward position by a bracket permitting pivotal motion of the gun-about such connection and toward the rear by means in accordance with the invenition, the vertical and lateral adjustment secured by such means will impart motion of elevation and depression to the gun and motion in azimuth, and in the latter case the adjustment will be such as to produce, where several guns are provided, for instance, diverging or more usually converging fire.
I claim:
1. Gun mountings and more particularly mountings for machine and other relatively light guns in aircraft and other vehicles, comprising a main bracket adapted to be secured to the mounting of a gun and associated with the main bracket a gun bracket with which the gun may be directly connected, a screw-threaded element adapted to be rotated for effecting the movement in a vertical direction between the gun bracket and the main bracket, an eccentric rotatably mounted on the screw-threaded element, means on the gun bracket engaging such eccentric, means for rotating the eccentric to efiect displacement of the gun laterally and a locking nut adapted to lock the screw-threaded element and the eccentric to secure the gun bracket in. the position with respect to the main bracket into which it has been adjusted.
2. Gun mountings and more particularly mountings for machine and other relatively light guns in aircraft and other vehicles, comprising a main bracket adapted to be secured to the mounting, a gun bracket in the form of a stirrup having in its base an elongated slot, a screwthreaded member extending through the slot and furnished with a head engaged between the base of the stirrup and a retaining plate extending over the base of the stirrup and rigidly secured thereto, ribs on the lower surface of the base of the stirrup, a block slidable therein and provided with a hole, a block eccentrically mounted on the stem of the screw-threaded member and engaged in the hole, a thumb piece on the eccentric block whereby it may be rotated about the axis of the screw-threaded member in imparting a traversing motion to the gun bracket, an externally screw-threaded 'bush on' the screw-'' threaded member and secured thereto by a pin and slot, a milled headed nut in screw-threaded eng ement with thebush and entering a hole in the main bracket, and a locking nut in screw? threaded engagement with the screw-threaded member and disposed on the side, of the main bracket remote from that adjacent to said milled headed nut for locking the several elements into the position in whichv they have been adjusted byrotation of the milled headed nut and by the rotation of the eccentric block about the axis of the screw-threaded member.
