Projecting upwardly from the base plate In into the bore 32 is a bolt 34 for use in fastening the base to the elevator C. The traversing bearing member II also has an offset portion 35 provided with two vertical holes 36 and 3'1, the purpose of which will be described later herein.

Fig. 6 shows the elevator C as comprising a lower conical bearing portion 38 having a downwardly projecting cylindrical element 39. This element has a bore 46 (dotted lines) for receiving the bolt 34 of the base member. Extending upwardly from the conical portion 38 is an angled tubular support 4!, the upper portion 42 of which is disposed parallel to but spaced forwardly from the vertical axis of the base member it, when the parts are joined as shown in Fig. 1.

The upper edge of the conical portion 38 has a lateral lug 43 secured thereto. The lug 43 carries a spring button 44 having a pin (not shown) adapted to enter either of the holes 35 or 37 in the offset portion 35 of the base (see Figs. 4 and 6). Thus, the elevator may, if desired, be locked in two points of its 360 path in traverse.

Fig. 7 is a perspective View of the cradle yoke D. yoke is provided with a pintle 55 which fits firmly in a central bore 48 of the upper portion lf? of the elevator, so that the cradle yoke traverses together with and as a part of the elevator. For this purpose the lower end of the pintle 55 has a circular groove 47 which is engaged by a bolt 48 threaded through the elevator wall and a projecting lug 49 thereon. The

bolt :38 is provided with a tightening handle i), as shown in Fig. 2.

The arms 5| of the yoke D have aligned openings '53 for the insertion of a trunnion pin 54 (Fig. l) on which the cradle E pivots during its vertical movement.

The arms 5! of the yoke D also have two sets of aligned holes 2 and 4, the first being adapted to receive a cradle locking pin 56 and the latter for receiving a gun locking pin 51 (see also Fig. 2).

The cradle E, perhaps best illustrated in Figs. 1, 3, 8 and 9, is comprised of two side plates 58 and 59 disposed in spaced parallel relationship to receive a gun G therebetween. The gun is secured in position by the locking pin 51, to which reference has already been made, and which also passes through the side plates 58 and 59 of the cradle E as seen in Fig. 3. A second locking pin 6% similarly secures the rear portion of the gun G to the cradle.

At the rear the main cradle plates 58 and 59 have the parallel arms GI and 62 (see Fig. 9) which spread laterally as at 63 and then again are parallel at their rear end portions 64 and 65. These rear end portions are braced by the transverse support 65. Secured to these rear end portions 54 and 55 are operating handles 61 and 58 which extend laterally. The handle 68 is provided with a pivoted firing lever 69 (see Fig. which when depressed will fire the gun through the following mechanism.

With reference to Fig. 10, the firing lever 69 has a curved hooked element 10 which engages a lug H on one end of a double armed lever 12 (Figs. 8 and 9). The other end of the double armed lever 12 is connected by a link 13 to a triangular plate M which is pivoted as at E5 to a bracket l5 rigid with the cradle. The bracket also supports a trigger control mechanism ll 4 having an actuating lug 18 which is connected by a link 73 to the triangular plate 14. The trigger control mechanism '11 has a lug (not shown) which engages the firing mechanism of the gun.

It should be clear that depression of the firing lever 33 will pivot the double armed lever 12, moving the link 13 downwardly, pivoting the triangular plate l' l, thus pulling link E9 to the rear (Fig. 8). This action results in drawing the actuating lug 73 of the trigger control mechanism 'l'l rearwardly and firing the gun.

An important feature of the invention resides in the extension frame F.

The extension frame F is mounted at the rear end of arms 54 and 65. It is comprised of the extension members and Bi disposed in parallel relationship and joined near their outer ends by a transverse support 82. The extension members 8G and 3! are provided at their outer ends with lateral hand grips 83 and 84, and a pivoted firing lever is disposed adjacent to hand grip 84 (see Fig. 10).

The firing lever 85 is connected by a rod 86 to the double armed lever 12 so that actuation of the firing lever 85 will pivot the double armed lever 12 to fire the gun, in the same manner as firing lever 69 described hereinbefore.

The extension frame F is employed for firing primarily when it is in upright position as shown in Figs. 1, 2 and 10, but it may be swung into inoperative position beneath the cradle because of pivoting arrangement which will now be described.

The rear ends of the arms 6 65 are each provided with a vertical projection 88 (see Fig. 11). The extension members 89 and BI are tubular and their lower ends are slotted longitudinally as shown in Fig. 11. The lower ends of the extension members till and 81 are pivoted as at 853 to the arms 64 and 65 respectively in such manner that the projections 88 are straddled by the slotted ends of the extension members. When the extension members are in the position shown in Fig. 10, the slot will be seen to accommodate the full extent of the vertical projection 88 on the arm 65. To retain the extension frame in such position, the extension members are each provided with a tubular sleeve 99 which is slidable in a longitudinal direction and which, in the position shown in Fig. 10, will prevent the extension members '80, ill and the frame F as a whole from pivoting, thus securing it in up-- right position.

When it is desired to swing the extension frame F to its inoperative position (shown in dotted lines in Fig. 1), the tubular sleeves all are slid upwardly above the projections 81 and 83, and the extension frame F may then be pivoted rearwardly, downwardly, and underneath the cradle. It may be secured in such inoperative position by spring catches 9! (Fig. 1) carried by the sides of the cradle and which engage the extension members 8B and BI.

It will be noted that a machine gun mount constructed in accordance with the invention is a versatile instrument. With the mount on flat ground and with the extension handles in an upright position the gun may be fired with the gunner in standing position, or in a squatting position. Moreover, if a circular trench is dug for the gunner around the mount, the gun may be fired either by the firing lever at the rear of the cradle or by the firing lever at the free end of the extension frame, depending on the elevatlon of the gun barrel.

, when fired by the firing lever on the extension frame.

Moreover, it will be appreciated from the disclosure made that the mount is easily disassembled so that the base, the legs, the elevator, the yoke and the cradle may be separately transported.
