The invention described herein may be manufactured and used by or for. the Grovernment for governmental purposes, without the payment to me of any royalty thereon.

The subject of this invention is a gun carriage. V p

I The principal object of the present invention is to provide a gun carriage in which the pedestal may be readily lowered to an emplaced position on the ground and elevated therefrom to a travelling position.

A further object is to accomplish the. foregoing movements through rotation of the Wheels of the carriage and in the event of failure of the wheels due to lack of traction the elevation and depression may be performed through the means normally employed to" hold the pedestal against movement.

With the foregoing and other objects in view, the inventionresides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention. I A practical embodiment of the invention is illustrated in the accompanying drawings, wherein: r

Fig.1 is a view in side elevation, with the near wheel removed, of the improved gun carrriage shown in the travelling position.

.Fig. 2 is a similar View of the carriage in the emplaced position.

The gun carriage comprises a wheeled axle unit A on which is mounted a pedestal B that rotatably supports a top carriage O. A cradle D trunnioned in the top carriage C carrles a reciprocab le gun barrel E. A pair of trail members FF each secured. to the 5 base by means of a vertical pivot pin'5.

Referringto Fig. 8 the axle unit A includes an axle 6 whose spindles 77 are each mounted in a bearing 8 of the wheels .9. A

brake drum 10 is secured to each wheel and a cover 11 for the drum is splined on the axle. A brake band 12 carried by the cover and actuated by the linkage 13 (Fig; 6) serves to internally engage the drum 10 and thereby couple the axle and the wheel. An T actuating mechanism 14 applies to the linkage 13 for both wheels.

A pair of spaced gear wheels 15-45 are fixedto-the central portion of the axle. A

block16 is journaled on the axle on the outside of each of the gear wheels and is formed on each side with a vertical flange 17 providing a groove 18. The vertical side of the front plate 19 and back plate '20 of the pedestal are provided with tongues 21 fitting in the grooves18 and enabling the pedestal to be guided in vertical movement relative to the blocks 16 on the axle.

Within the pedestal and vertically movable relative thereto is a rack member consisting of a front plate 22-, a backplate 28, and a connecting base plate 24 disposed underneath the axle. The side portions of the

plates

22 and 23 fit between the

plates

19 and 20 and the blocks -16 and are laterally'con- Y fined by the flanges 17 of the blocks. On the inside of the front plate 22 are a pair of spaced racks 25 25 each meshing with one of the gear Wheels 15 on the axle. per ends of the racks terminate short of the top plate 26 of the pedestal.

The base plate 24 of the rack member has a pair of extensions 2 727 projecting beyond the front and back plates 22-23 and 7 adapted to seat a helical spring 28 disposed within a partially cylindrical portion 29' on the front end on the backplate of the pedestal. The springs engage the topplate 26 and yieldingly. support the pedestal. The portion 29 on the back plate has a stiffening mem- The up- 35' and are held thereby in engagement with the ratchet wheel to prevent rotationof the shaft in opposite directions.

A lever 36 also pivoted .on the block 16be-;

tween the pawls is formed with a pair of opposed arms 3737whi ch upon rotation of the lever are adapted to selectively'cam one of the pawls from engagement with the ratchet wheel; i I On one end of the shaft 31 there is a ratchet wheel 38, for" application of a ratchet wrench39. f

In the travelling-position, Figs. 1 and 3, the pedestal is yieldingly supported on the springs 28 and the rack member is locked to the axle 6 through the pinions 32 on the shaft 31 which is held against rotation by the pawls 34, 'The'axle is disconnected from the wheels so that'it does not rotate therewith. v The operation of 'e mplacing thepedestal by lowering it to the ground as seen in Figs. 2 and 4 consist in connecting theaxlefto the wheels by applying the brake band 12 and thendisconn'ecting one of'the pawls 34"to allow for rotation of the shaft '31. 'The gun carriageis thenmoved and,:as the wheels turn, the axle will berotated and the gear wheels 15fin'engagement with the racks 25 will provide: a controlled lowering of "the rack member and the spring supported pedestal B until the'pedestal rests on: the ground in position for firing; A reversal of the foregoing procedure restores the pedestal to the elevated or travelling position.

' When there is insufficient traction for the wheels to hold the load during elevating, the wheels are disconnected from the axle and the ratchet wrench 39-is acted on to'rotate the shaft 31, whichfthrough its pinions 32 ro ftates' the axle and consequently elevates the rack member and the'pedestal carried-there by. The rack member may belocked'against movement in-any position by-merely engaging both of the pawls 3,4: withthe ratchet wheel 33 on the shaft 31.
