COMBINATION MOUNT FOB MACHINE GUNS.

Application filed August 20, 1925. Serial No. 51,464.

(GRANTED UNDER THE ACT OF MARCH 3, 1883; 22 STAT. L. 625.)

This invention relates to a combinationmount for machine guns.

The principal ob ect of the present 1nvention is to provide a conveniently foldable machine gun mount of the tripod type which in its normal application as a low mount when the gun is directed against ground targets insures stability and rigidity, and which may be instantly converted to a high mount when the gun is to be directed against aerial targets.

It is desirable because of weight limitations that in accomplishing this dual pur pose the mount be not burdened with auxiliary devices and it is essential that there is preserved facility in manipulating the gun and adjusting the mount to its firing and folding positions.

Accordingly, I employ a mount of the split trail type in which a front leg passes axially through the tripod head. The element which serves to mount the gun for firing against both ground and aerial targets embodies a cradle pivoted to the head of the front leg. In its normal adjustment for low angle firing the cradle trunnions the gun at its forward pivoted end, the rear end carry" ing an elevating mechanism and held rigid by being removably attached to an extension on the foot of the front leg. In converting the cradle to an anti-aircraft adaptor to mount the gun for high angle firing it is disconnected from the extension and swung to the vertical, the rear end now serving to trunnion the gun by the same means through which it was connected to the extensionv To these and other ends, my invention consists in the construction, arrangement, and combination of elements, described hereinafter and pointed out in the claims form ing a part of this specification.

practical embodiment of the insenfien is illustrated in the accompanying drawings, wherein Fig. 1 is a view in side elevation of a nount constructed in accordance with the invention and adjusted for low angle firing;

Fig. 2 is a plan view thereof with the gun removed;

Fig. 8 is a view in side elevation with the cradle swung to the vertical position to be used as an anti-aircraft adaptor;

Fig. 4 is a detail view of the stem Fig. 5 is a detail View of the nut;

Fig. 6 is a sectional view on the line 6-6 of Fig. 3, the legs removed.

Referring to the drawings by numerals of reference In carrying out the invention there is provided a tubular head 6 to the upper end of which are pivoted a pair of trail legs 6-6. Each leg is equipped with a brace 7 pivotally secured to the base of the head and jointed to the leg by a sliding clamp 8 whose movement provides for folding and for adjustment of the leg to conform to the contour of the ground. Locking of the brace is ef fected by means of a clamping handle 9, which in the present instance, binds the brace but may equally well be arranged to bind the trail leg.

Inserted in the tubular head 5 is a stem 10 constituting the front leg of the moun and terminating in a point 11 to facilitate entrance into the ground. For convenience in assembiing, the foot of this leg is preferably a composite unit consisting of a collar 12 held in place by means of a nut 12 threaded on the stem and receivable in a re cess in the collar. The nut is headed and of convenient shape for contact with the ground. The collar is formed with an angled extension 13 for a purpose which will presently be described.

The head 10 of the stem consists of a block provided transversely with a front aperture 12 and a rear aperture 15. A cradle 16 comprising a pair of spaced plates 17-17 is permanently pivoted at its 8K- treme forward end by means of a pin 18 through the aperture 155 Ian mediately above and in rear of this permanent attachment the cradle plates are each formed with an aperture 19 for receiving a trunnion pin 20 for mounting the gun when it is to be directed against ground targets. The trunnion apertures 19 are so positioned that they will be in alignment with the front aperture 14 in the head 10 and may there receive the trunnion pin 20 to secure the cradle in a vertical position when it is to be used as an anti-aircraft adaptor in high angle firing.

In the normal low mounting the rear end of the cradle is directly secured to the extension 13 by means of a removable pin 21. This pin serves as a trunnion pin for mounting the gun when the cradle is in the vertical position, as seen in Figure The extremities of the cradle are preferably oifset at approximate right angles so as to obtain a proper disposition of the cradle Without increasing its size and weight.

The cradle also carries at its rear end the housing 22 of an elevating mechanism 23 operable in a well known manner. The attachment of the housing serves as a spacer for the cradle plates in both positions of adjustment.

In traversing the gun the front leg or stem moves with the cradle which in the low mounting bears such relation to the trail legs that the amplitude of its traversing movement is defined thereby. This prevents the gunner from inadvertently moving the gun beyond the spread of the trail legs and insures stability during firing.

The mount folds umbrella fashion making a compact and neat unit for transportation while permitting it to be quickly erected.
