v The matter disclosed and claimed herein constitutes a division. of application filed April 2.6, 1926, on ordnance,Ser. No. 104,882.

This invention relates to ordnance, with particular reference to anti-aircraft rdnance.

So far as known, anti-aircraft ordnance has been d esignedfor such use only, to the exclusion of ordinary field or naval ordnance purposes. Similarly large caliber ordnance such as is used on naval vessels. for instance, has been incapable of use against aircraft, due among other factors, to the slight degree of elevation to which such ordnance is susceptihle. This results not only in undue duplication of ordnance, but also 111 ineffective anti-aircraft measures.

Further, it has been thetend'ency and practice to provide as anti-aircraft ordnance devices with a highrat'e of fire but with an attendant decrease in bore of the rifle, and in the size and weight of the projectiles. The hope being that a cone of fire'will' be provided of great intensity, of such divergence 5 that one or'more of the small projectiles may strike the target air-craft. Such anti-aircraft ordnancea-nd', fire have been proven' to be ineffectual.

Some of the object-s of thisinven on are:

to improve the mounting of large caliber ordnance to permit its use against aircraft without in any way reducing the offensive power of the gun when firing at ships on the surface of the water. or lowering the resistance factor '35- of the turret in which the gun is mounted;

to provide means whereby highly effective firing may be had against aircraft; and many other objects and advantages as will be apparent.

In carrying out this invention a turret or similar mount for a gun is provided, which is so arranged that aiming and firing of the gun may be had in two perpendicular planes,

. effective for either long range or high elevation purposes.

In the accompanying drawings:

Fig. 1 is a vertical section through a turret, of a naval vessel for instance, which turret has movement about a vertical axis and also abouta horizontal axis, with the gun; in its normal horizontal position,

Fig.-

is a similar sectionto Fig. 1, but with the turretin a slightly different position about its horizontal axis, and with the gun shown, in an elevated position for antiaircra-ft fire;

En anti-aircraft fire, the vital spot of the target has always been consideredto be the pilot. It has been found that expeditious results maybe had by causing some collapse of'the airplane structure, such asa strut, pro peller, flying wires, and that such collapseis as effective as a hit on the' pilot.

While, of course, there is always a chancethat the present construction and firing of anti-aircraft ordnance willin isolated cases result in hits, yet there is a tremendous waste of munitions with no certainty of'a hit; Frequently such projectiles as make hits, pass through wings or other innocuous places,

without any appreciable damage.

Thisinvention contemplates-a reduced rate of fire if necessary, but results of high effi ciency from each shot. lVith that portion of' the invention pertaining to-improvement of the mounting of large calibered ordnance, such as the 12, 14 and 16 inch guns, it will be perfectly feasible to fire either high explosive shells, the conventional shrapnel, or even gas shells, a-nd'good results should be obtainable from any of these.

For greatest effectiveness it is contemplated that proj'ectileswould be used with large caliber' ordnance which may be made available for such anti-aircraft orother fire as shown in Figs. I and 2', although obviously smaller Referringnow to Figs. I and Qof'the draw "To obtain such high angles the gun 22, is

mounted on trunnions 23, eccentric with the vertical axis, being rather close to the lateral edge of the turret. The armored dome 24 is mounted for rotation about a horizontal axis as well, as by means of bearings 25, carried on the turn table 26 of the turret. The dome 24: has a gun port :27 through which the gun or rifle extends and which may be made gas tight in any desired manner. Inthis and the other forms disclosed it requires but a slight modification of the armor surrounding the gun port to afiord ample'protection to the trunnions and recoil cylinders of the conventional riiie. In the form ust described it will be seen that with the eccentric pivoting of the gun, a great variation in the vertical angle of the gun may be had with a minimum movement of the turret dome 2-l on its horizontal axis, so that 90 elevation may be had with but perhaps 20 or" movement of the dome. It will be understood that mechanisms for operating the gun and the several cooperating parts may be provided asdesired.

Many changes and modifications or" this invention may occur to those skilled in the a rt, and all such are to be considered as within the scope of the following claims, except where they may otherwise be limited. For instance land fortifications require high angled fire, unobtainable except with such turrets as those described.

I claiai as my invention:

In a gun nount, a. tin-re", an armored wall forthe turret havinga gun port, a gun extending through the port, trunnions pivotally supporting the gun, means for pivotally supporting the armor for movement rela tive to the trunnions on an axis eccentric to the trunnions, means for varying the rela tive position of the port in relation to the trunnions whereby said gun may oscillate on the trunnions through a full 90 vertically according to the relative positions of the trunnions and port. I

2. In a gun mount, a turret, an inclined armored wall or? the turret having a gun port, a gun extending through the port, pivotal means for supporting the gun on a horizontal axis means for pivotally supporting the arm or for movement relative to the trunnions on an axis eccentric to the trunnions, means for varying the relative positions of the axis and said port whereby the axis and the port may be in substantially a horizontal plane for horizontal firing of the gun, and may be in substantially a vertical plane for vertical firing of the gun or in any adjusted position therebetween.

8. In a gun mount, a turret including an armored inclined wall, said wall having a gun port above the lower edge of said'wall, a gun projecting through said port, means for supporting said gun on a horizontal axis in such position as to fire substantially horizontally, and means for efiecting a change in the port whereby a minimum oscillation of V the armor permits a maximum oscillation of the gun. V v

5. A gun mount including a turret having armor, the armor having a port of less than conventional size, a gun projecting through the port with a minimum clearance in the port, means for pivoting the gun on a horizontal axis relatively close to the port, means for oscillating the armor on an axis parallel with the gun axis but relatively remote therefrom, and arranged so that an oscillation of the armor through substantially 20 moves the port to a point substantially vertically aligned with the axis of the gun to permit a full 90 oscillation of the gun on its axis.

6. In a gun mount, a turret, an armored wall ot'the turret having a circular gun port, a gun extending through the port, trunnions pivotally supporting the gun within the turret means for pivotally supporting the armor for movement relative to the trunnions on an axis eccentric to the trunnions, means for varying the relative position of the port to the trunnions whereby said gun may oscil-.

late on the trunnions through a full 90 vertically according to the relative position of the, trunnions and port.
