(FILED UNDER THE .ACT 0F MARCH 3, 1883, 22 STIAT. L., 625.)

Be it known that we, JOHN S. BUT- LER captain, Ordnance Department, United States Army, and SAMUEL G. GREEN, lieutenant, lOrdnance Department, United States Army, citizens of the United States, stationed at Washington, lDistrict of Columbia, have inventedan Improvement `in Bipods, of which the following is a specificatiom The invention described herein may be used by the Government, or any of its oilicers or employees in prosecution of work for the Goverment, or by any other person in the United-States, without payment of any royalty thereon.

Our invention relates to supports for guns, and more particularly to a; support for a Browning heavy machine gun, and has special reference to the type of gun supports known as bipods (as distinguished from tripods.)

lThe object of the. invention is to provide a bipod which may be conveniently use d while the operator is in a recumbent pos1 tion, 'as when he is lying on the ground;

which is simple in organization; which is relatively light in weight, yet strong and durable in use;` and which embodies novel means permitting traverse and including' 'means limiting the traverse and, also,- preventing accidental disengagement of the os cillatory turret.

Subordinate objects relating to matters of specific structural' improvement lgoing Eto .make upthe ultimate perfection of the en-v tire device will appear as the-specification proceeds, and the nature of the invention more fully appears.

The accompanying drawings disclose an exemplaryv embodiment of the underlying principles of the invention, like reference characters indicating corresponding parts throughout the several views, which -Vlatter may be brieiiy described .as follows v Figure 1 is a view in sidev elevation of our bipod; v y Fig. 2 isa view in rear end elevation, partly in section, thereof;

1Fig. 3 is a fragmentary plan view of the bipod with the turret .removed through this tongue.

Fig. 4 is a detached detail plan view of,

the pivoting disk of the turret; and

, Fig. 5 is a fragmentary vertical sectional legs 1, 1 and may be conveniently positionedbetween the lower ends thereof as shown. The 'bent terminals of the brac 4 are riveted or otherwise suitably secur d to the legs Spikes 5, 5 are carried. bythe legs 1, 1 and may be securedvagainst the bent terminals of the'brace 4, as by riveting.

If desired, angle irons 6, 6 mfay be secured to the top of said spikes 5, 5, as by" riveting. The lower bent terminals of the angle irons are substantially in the plane of the leg- terj minals 3, 3 and constitute auxiliary means for bearing against thev ground when the bipod is in use.

Riveted, or otherwise suitably secured to the bridge 2, are angle plates 7, 7. I t

A disk 8 is riveted to said angle plates, and is provided with segmental marginal inturned lip 10 at its top. Said segmental flanges l9, 9 are `symmetrically arrangedso that corresponding ends thereof are equally spaced, as shown clearly in Fig. 3. The disk is also provided with a central boss 11v through which and through the bridge 2 may pass a fastening member 12 carrying a 'nut 13.

Between the disk 8 and thejbridge2 is disposed a resilient tongue 14; and, desirably, the fastening membery 12 projects The tongue carries a pin 15 projecting through a peripheral notch 16 in the disk 8 intermediate twoadjacent ends of the flanges 9, 9. p

The",` oscillatory turret comprises, in this flanges 9, 9, each of which has a coextensive -secure b instance, a channel plate 17 and a cradle 18. The cradle is preferably a bow shaped plate provided, at its forward end, with a tongue 19, which is bent under and secured to the plate thus forming a loop 20. The cradle is provided, at its sides, with arms 21, 21 bent downward and under the cradle and secured thereto.

support is provided for the machine gun, to take up jar and vibration iand prevent them being transmitted to the legs 1, 1.

Carried on the .under surface of the channel plate 17 is a pivoting member, comprising, in this instance, superposed disks 22, 23, each of which is provided with a registeringv central aperture 24, through which the boss 11 projects (as shown in Fig. 5). The disks 22, 23 may be secured to the member 17 by rivets 25. The disk 23 is provided with diametrically opposite tongues 26, 26. By'disposing themember 17 so that the tongues 26, 26 are between the correspondremoval of the turret from its support, as is evident, since, by its position, it prevents the tongues 26, 26 passing entirely from beneath the lips 10, 10.

In compliance with the patent statutes, we have described, with great particularity, a specific embodiment of ouninvention; but the spirit of the invention is necessarily independent of l.the structural details, which may bechanged, as desired. Therefore, all modifications as come within the scope of the appended claims are within the range of our invention. l y

Having thus fully described our invention, what we claim as new and desire to Letters Patent is 1. A ipod including a removable turret mounted for traverse, and a resilientlysupported member in the path of movement of said turret for limiting traverse and: preventing accidental removal of the turret. 2. A bipod comprising a turret, supportlng means therefor having flanges providing overhanging turretretaining lips, and means normally preventing removal of said turret from said lips and limiting the traverse of the turret.

3. A bipod comprising a turret, supporting means therefor having longitudinallyarcuate flanges providing longitudinally-arc uate` overhanging turret-retaining lips, andv means normally preventing removal of said turret from said lips and limiting the traverse of the turret.

By this construction of. cradle,. a somewhat yielding or springing'l 4. A bipod comprising a turret, supporting means therefor having flanges providing overhanging turret-retaining lips, and a member normally in the path of movement of said turret for preventing removal there' 'of from said retaining lips and limiting the traverse of the turret.

5. A bipod comprising a turret, supporting means therefor having flanges providing overhanging turret-retaining lips, and a resiliently-supported member normally in the path of movement of said turret for preventing removal thereof from said retaining -lips and limiting the traverse ofthe turret.

6. A bipod comprising a turret, supporting means therefor having flanges providing overhanging turret-retaining lips, and means normally preventing removal of said turret from said retaining lips,'comprising a resilient tongue carrying a projection normally in the path of movement of said turret.`

7. "A bipod comprising a'movable turret, and `stationary supporting means therefor having flanges providing overhanging lips, said turret carrying means movable' beneath said lips to hold the turret against accidental removal, and movable from beneath said lips to permit removal of said turret.

8. A bipod comprising a movable turret, and a stationary disk upon which said turret moves and having segmental flanges providing overhanging lips, said turret carrying tongues movable beneath said lips to hold the turret against accidental removal, and movable from beneath said lips to permit'removal of said turret.

9. A bipod comprising a movable turret, and a stationary disk upon which said turret moves and having segmental flanges providing overhanging lips, said turret carrying tongues movable beneath said lips to hold the turret against-accidental removal, and movable from beneath said lipsA to permit removal -of said turret, and a movable `member in the path of movement of said l providing overhanging lips, said turret carrying tongues movable beneath said lips to hold the turret against accidental removal, and movable from beneath said lips to per- -mit removal of said turret, and a movable member disposed between two ad'acent ends of said flanges and in the path o movement of said tongues for limiting traverse of said g turret.

11. A bipod comprising a. rotatable turret and 'a stationary disk upon which said turret revolves and having segmental flanges providing overhanging lips, said turret carrying tongues movable beneath said lips to hold the turret against removal, and movable from beneath said lips to permit removal of said turret, and a Vresiliently-supported member in the path of movement of said tongues for limiting traverse of the turret.

12. vA bipod comprising a rotatable turret 5 and a stationary disk upon which said turret lrevolves and having segmental anges providing overhanging lips, said turret carrying tongues movable' beneath said lips, to hold the turret against removal, and mov- 10 able from 'beneath said lips to permit removal of said turret, and a memberlimit-l ing traverse of the turret and preventing accidental removal thereof.
