PEDESTAL MOUNT FQR GUNS.

Application filed 'Iannary 30, 1924. Serial No. 689,489.

(FILED UNDER THE ACT OF HAIR-0H 8, 1883, 22 STAT. L, 625.)

To all whom it may concern:

Be it known that I, THOMAS A. CONLON, a citizen of the United States, and a resi dent of Silver Spring, county of'Montgomcry, and State of Maryland, have invented an Improvement in Pedestal Mounts for Guns, of which the following is a specification. I The invention. described herein may be used by the Government, or any of its ofiicers or employees in prosecution of Work for the Government, or by any other person in the United States, without payment to me of any ro alty thereon, in accordance with the act 0 March 3, 1883.

The present invention relates to pedestal mounts for guns and particularly to that type of pedestal mount employed with antiaircraft artillery.

In using large caliber guns and guns of the anti-aircraft type, it is absolutely essential for correct aiming that some means be provided in the gun mount for maintaining the cradle trunnions in a horizontal plane at a5 fall times when the gun is moving in azimuth. The structures employed, heretofore, fdr maintaining the true horizontal position of the cradletrunnions have been expensive to construct, diflicult to o erate and involve a multiplicity of complicated parts which readily get out of order.

The primary ob ect of the present invention isfto provide a leveling device for guns by means of which the gun cradle may be maintained at all times in a true horizontal position regardless of the configuration of the ground upon which the gun is mounted.

A further object of the invention is the provision of a gun mount in which ease of operation, simplicity and inexpensiveness of construction are distinguishing characteris tics.

With the foregoing and'otherobjects" in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit cf the invention.

A preferred embodiment of mv invention is illustrated in the accompanying drawing, in which,

Fig. 2 is a section on the line 2--2 of' Fig. 1.

eferring to the drawing by numerals of reference;

have shown a base 5 which may be positioned upon a permanent gun emplacement or upon a movable gun carriage. Mounted upon the base 5 and secured thereto as by means of bolts 6, is a. pedestal 7. A supportingmember 8 mounted upon the pedestal? serves to carry the upper gun carriage with the cradle and gun attached thereto. This supporting member 8 is mounted on the pedestal 7 so as to have universal movement with respect thereto, thus the pedestal 7 at its u per end may be formed with a socket 9 a( apted to receive a ball-head 10, preferabl formed integral with the'sup-porting mem er 8.

By moving the supporting member on the pedestal should the gun be found to be un evenly positioned, the cradle may be always maintained level. For movin the supporting member with respect t t e pedestal, l.

referably employ a pair of movable memrs 11 and 12 mounted on the pedestal and reciprocable in paths at right angles to each other and connected to the supporting member 8 in such manner that the total movement of the reciprocating members is communicated to the supporting member so as to maintain the gun in its proper level position.

The movable member 11 in the embodiment of my invention, is screw threadead so as to move upon an actuating bolt 13 mounted upon the pedestal as by referred I means of brackets 14. 'For guiding themember 11 in its reciprocating movement.

bars 15 may be provided, which are attached screw thread and is mounted upon a bolt 18 which is journaled at either end in the cross bars 19 of the member 11.

Any suitable means may be employed for connecting the movable members 11 and 12 to the supporting member 8 so that the movement of the members 11 and 12 may be communicated to the member 8 to maintain the gun in a true horizontal position. As shown, the member 8 is formed at its lower end with a recess 20 adapted to receive a spheroidal connectin member'2l which is preferably formed integral with the movable member 12.

For actuating the members 11 and 12 rachets may be employed connected by collars 22 to the bolts 13 and 18, respectively. The rachets may be manipulated by levers 23 pivoted to the collais 22 and normally held in inoperative position against the pedestal 7 by catches 24; Four rachets will be provided, preferably, one for either end of a bolt. r

In operation, my device may be employed as follows:

v"When the gun has been brought into position and. it is found that the trunnions are not in a horizontal plane, the bolt 18 or the bolt 13 or both bolts will be actuated to move the members 11 and 12 so as to correct the position of the cradle trunnions. In this way, the supporting member 8 will be moved and with the member 8 the cradle so that the gun at all times may be maintained in a true horizontal position.

The pedestal forming the subject of this invention, is easy to construct, simple in operation and requires but a few easy wor ing parts. It will not get out of order in or inary'use and avoids the many difficulties met with in the leveling pedestals heretofore employed.

Havin thus described my what I c aim is:

1. A leveling device for guns including a pedestal, a supporting member provided with a recess in its lower end mounted on the pedestal and adapted to have universal movement with respect thereto, a member mounted on' the pedestal and reciprocable in a rectilinear path in one plane, said member provided with a longitudinal groove transverse to its path of movement, a second member mounted on the first member and adapted to move in rectilinear path in the groove of the first member and be guided thereby, means secured to the second member and adapted/co seat in the recess of the supporting member to move the supporting member on movement of the second member and means adapted to move each of the mlovable members. 1
