A pplicationgfiled refinery-11,1919. Serial unol' evaaea (FILED UNDER T rm or mean 3;,*1sss;'22- s raniigiezta To all whom it may) concern; V 7 Be 1t-lrnown that I, JOHN'S. BUTLER, captain ordnancedepartment, U. 7. SI. Army, a cit'izenrofthe United States, stationed at lVashington; D. 0., have invented an ,Im provement in Tripods for Machine-Guns, 0f "which'the following is a specification.

v The invention described herein may be used byi the. Government, or any )fv.its c fli-- cers oremployeesin prosecution of work for the Governmenu'oi' by any other person in the United States, without payment of-any royalty thereon.

This, invention relates to iinproveinentsin tripods for mach ne guns1and', r efers more particularly to tripods for Browning niachinefgunsof the type 'ada ted for use in; connection withmilitary tan rs, L

lVith the foregoing and other important objects in view my invention comprises the new and useful details of construction and arrangement which willbe hereinafter fully described, illustrated in the anneXedvdraw-V ing; and pointed out more specifically in; g and by the appended claims.

In the accompanying drawings wherein the preferred embodiment of my invention 7 w is shown like reference characters 'refer to like and corresponding parts throughout'the Inthe drawings i Figure 1 isthe side elevation of nay-tripod shown in its operating relation with the machine gun of the tank" type; Fig. 2'is'a similar View of my device folded and strapped tothegun. r

A strap 32 which is riveted to one of thelegs lS ati 33 is then buckled aboutthe' tripod and gun I as is clearly shown in Fig. 2. V

From the foregoing descriptio'n'it will be readily seen that my invention provides a tripod which is read-1y adaptable for'use with a tank gun especially when the gun is being used in an emergency by an operator in a prone position and that the same be easily andquickly folded and strapped to the gun for transportation. 7

Having thus described my inveiitiolnwliat I- claim as new and desire to protect 'by Letters Patent is: i

1. A tripod for a machine gunor the like,

including a clalnp for engagement with the gun, a bracket carried by the clamp, a yoke hinged to the bracket, a rear leg fixed to the yoke and adapted to be swung beneath and. longitudinally of the gun barrel when not in use, and front legs pivoted to the yoke and adapted to be swung into engagement with the rear leg when the tripod is not in use.

2. A tripod fora machine gun,.including a bracket, means for pivotally securing the bracket to the gun, a rear leg fixed to the bracket and adapted to be swung beneath,

and longitudinally of the gun barrel when not in use, and front legs pivoted to the yoke and adapted to be swung into engagement with the rear leg.

3. A tripod; for-machine guns, including a yoke formed with depending flanges, means for pivotally securing the yoke to a machine gun, a leg fixed between the. flangesand 7 adapted ftobeswung beneath and longitudinally of thegun barrel when not in use, and

to said yoke,' said yoke provided with di agonally'extending wings, diagonally and forwardly diverging front legs pivoted'to said wings, and an arcuatebolt bridging the space between said wings in position to limit the'f orward divergence of said legs. 5. In combination with a machinegun, a tripod therefor having a clamp detachably engageable with the gun, a transversely hinged bracket carried by the clamp, a central yoke vertically pivoted to the hinged bracket, a rearwardly extending leg fixed to a the yoke, diagonallyand forwardly diverging front legs. pivoted to" the yoke, stop means on said yoke in position tolimit the forward divergence of said.legs,.and spring means carried by theyoke in position to detachablyenga'ge the front legs in the spread position.
