in place,

Patented Dec. 20, 1949 enliven STAT s s PATENT c tric The invention described "herein may be manu- -factured and used 'byor for the Government for governmental purposes without the payment to meet any royalty thereon.

- 'My invention refers to improvements in machine 'gun 'mountswhich will combine the advantages of mobility, rigidity'and safety.

An important object of the invention is to provide a metal wheeled machine gun mount "which'can be moved quickly from 'one position to another, and which can then be placed in immediate operation.

Another object of the invention is to provide a metal wheeled machine gun mount which will furnish rigid and stable support to the gun when operating.

A furtherobject of the invention is to provide a metal machine gun mount which will furnish some degree of protection to the operators of the machine'gun.

Other objects and advantages of the invention will become apparent during the course of the following description.

The following drawings, forming part of the specification, illustrate the manner in which I attain these objects. Similar numbers are used to designate like parts throughout the same.

Figure 1 is a plan view of a machine gun mount embodying my invention with a machine gun Figure 2 is a rear elevation of the same, and

Figure 4 is a perspective view of the hinged body or mounting unit.

In the drawings the numeral 4 designates a tubular body, preferably circular in cross-section, having a circumferential flange Ad on the top, and terminating in a conical end b. The tubular body 4 is provided with diametrically disposed wings 5 having a plurality of holes therethrough for pivotally attaching the said body to a pair of steel cross pieces 6, each said cross piece having one bifurcated end forming a clevis having a plurality of registering holes in the opposed walls thereof to receive and engage said wings 5 therein by means of a fixed swivel pin 1 and for the insertion of a loose pin 8 attached to the steel cross pieces by a chain. When this loose pin is removed the tubular body will drop automatically and the conical end will enter the ground. The loose pin may then be inserted in other registering holes provided therefor and will hold the unit in its new position.

The steel cross pieces are bent at the end and arranged to receive the axle 9 which is attached thereto by a fixed swivel pin it and by a loose 2 pin llattached to the cros pieces by-a chain. When the loose pin is removed the solid metal wheels l2 may be swung laterally to provide protection-"for the operators of the machine gun and alsoadd to the ri'gidity of the mount. Braces '23 to which trail shoes M are rigidl attached, are attached to "the steel cross pieces by ball joints [5, and across brace l6 provided to separate the said braces when the gun is in opera-tidn. l v V I v c The operation of the machine gun mount is as follows: When the mount "bearing a machine gun has been brought into its position and loose position, the conical {end entering the ground B'are removed, the tubular body will pivot on the fixed swivel pins 1 and drop to its lower ts fix the ground position or the mount. The lo'ose pins are then inserted in the holes provided in {the wings 5 and the mount is fixed rigidly initsfnewposition. When the loose pin H is removed, the soli'dfmetal wheel 12 and its "axle '9 is swung forward, pivoting on the fixed swivel pin ll! an'd is held in its new place,

furnishing bothrigidity to the mount and a olegree of protection from "cross fire to the gun operators, when the loose pins H are-inserted in the holes provided in the'axle Q'for this purpose.

The braces t? which have'been'folded'in a Carryin'g'iiOsitio'n against the mount retained in said position by means of removable straps 6r "ties [3a while the gun'was being moved may *be "dropped to furnish back bracing for the mount, and are held rigidly in position by means of the cross brace I6.

It is to be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims.

Having thus described my invention, 1 claim:

1. A mount for machine guns comprising a tubular body portion flanged at the top and with a conical end, side flanges formed integral with said body, said flanges being provided with openings therein, steel cross beams pivotally connected at one end to said flanges, means for lowering and raising of the mount, stub axles pivoted to the other end of said cross beams and each arranged to swing about a Vertical axis, metal wheels on said axis responsive to the swinging movement thereof to assume a first position for moving the mount forward and a second position wherein said mount is lowered and said wheels are dis:-

posed at an acute angle to a vertical plane through the center of and toward the top of said mount, and at an acute angle to a horizontal plane through the center of and forward of said mount in which position said wheels are adapted to form a shield for the operators, cooperating means carried jointly by said cross beams and said axles, including pin-engaging registering opening in said cross beams and said axles, to selectively secure said cross beams and said axles in said first and second positions relative to each other.

2. A machine gun mount comprising a vertically disposed hollow body portion having a dependent ground engaging conical portion and a circumferential flange its upper end constructed and arranged to support a gun, rigid wings formed integral with said body portion on each side thereof, the said wings having a plurality of openings therein, a pair of steel cross pieces arranged at one end to engage said wings and at the other end to engage an axle, a pair of stub axles, each said axle being arranged at one end to engage a wheel, and having a pair of aligned openings 00- axial with said axle at the other end, pivot means therethrough, a pair of cross members, each said cross member having a clevis formed at one end to engage one of said wings for pivotal mounting therein, the opposed side walls of each said clevis having an opening arranged to register with one of the openings in a said wing to receive a removable pin cooperatively connecting said wings and cross pieces when the said cross pieces are aligned in a substantially horizontal first position and with another of said wing openings for similar pin connection of said wings and cross pieces when the said cylindrical member is translated downward and the said cross pieces are disposed downwardly and inwardly relative to the at each end of each said cross piece for pivotal r1 connection of a respective said wing and said axle therewith, removable pin means engaging said cross pieces and said wings to maintain said cross pieces in a substantially horizontal first position and for locking said cross pieces in a second downward and inwardly disposed position when the said body portion is translated downwardly on its pivotal connections, there being openings in said cross pieces arranged to register with openings in said wings when said body is in said first and second positions respectively, a second removable pin means engaging said cross pieces and said axles to maintain said axles in a plurality of adjusted positions relative to said cross pieces, there being openings in the adjacent end of each said cross piece arranged to register with one of the openings in said axle when said axle is swung on its pivot to such adjusted positions.

3. A machine gun mount comprising a vertically disposed hollow cylindrical member, the

dependent end of said member being tapered to form a ground engaging portion, the other end of said member being provided with an external circumscribing flange adapted to support a gun, a pair of diametrically disposed wings formed integral with said cylindrical member, each said wing being provided with a plurality of openings horizontal, the other ends of said cross pieces being flattened and provided with a plurality of openings therethrough, stub axles pivotally mounted on the respective flattened ends of said cross members for transverse swinging movement of said axles relative to said cross members about a normally vertical axis, the said stub axles having means on the ends opposite said pivotal connections to mount; a wheel, each said axle having an opening intermediate said pivotal connection and said wheel mounting means arranged to register with one of the openings in said flattened portion to receive a removable pin for cooperatively connecting said flattened portion and said axle when said cross members are in a substantially horizontal first position and with another said opening in said flattened portion when said axle is swung transversely relative to said portion.
