AIRCRAFT GUN.

Application filed September 3, 1921, Serial No. 498,430.

To all whom it may concern:

Be it known that I, KARL RosNnn, a citizen of Czechoslovakia, residing at Prague, Czechoslovakia, have invented certain new and useful Improvements in Aircraft Guns, of which the following is a specification.

My invention relates to air craft adapted to carry guns. As is known, aeroplanes have already been fitted with guns, which similarly to the machine guns, were arranged in the hull or in a boat of the aeroplane. Although small-caliber projectiles (2.5 cm. as a maximum) have been used, the attempts have failed, principally on account of the recoil, so that it was not possible touse such aeroplanes. It has further been proposed to provide guns of greater caliber in aeroplanes and to take up the recoil by the particular static structure of the aeroplane.

It is an object of my invention to provide an air craft gun, which is capable of taking part in a fight from the round. To this end the gun is so connecte with the flying machine, that it can only be fired after the machine is on the ground or on the water, respectively, so that the recoil is not taken up by the flying machine but by the ground or the water.

My invention is not limited to field guns but can also be applied to mine throwers and other pieces of ordnance.

The flying machine according to my invention is so designed that the gun is not disposed in the hull or boat of the machine but underneath it or, in flying machines having a double hull, in the middle underneath the bottom plate in direct connection with the landing chassis, so that the recoil is not taken up by parts of the flying machine structure, but directly by the ground or the water.

The gun can be permanently or removably connected with the flying machine. In the first case, the landing chassis is preferably connected with the carriage of the guns, while in the second case the flying machine and the guns have each a separate landing chassis, so that it is possible to use various kinds of guns, as desired, if the means of attachment are suitably constructed.

In the drawings affixed to this specification and forming part thereof, two flying machines embodying my invention are illustrated diagrammatically by way of example. In the drawings- Fig. l is a front elevation of an aeroplane with a permanently attached gun,

Fig. 2 is a side elevation,

Fig. 3 is a plan view of Fig. 1

Fig. 4 is an elevation of a modification, in which the gun is detachably connected with the aeroplane,

Fig. 5 is a side elevation of Fig. 4.

According to my invention, aeroplanes, having one motor or a plurality of motors and one hull or a plurality of hulls, monoplanes as well as biplanes, triplanes and so on may be used. 7

The example illustrated in Fig. 1 to 3 represents a biplane provided with two motors and three bodies, while the modification illustrated in Fi s. 4 to 5 is a biplane having one body and one motor.

a is the flying machine structure, I) the gun, a the gun carriage, which also forms the landing chassis of the aeroplane, while in the modification illustrated in Fig. l-the gun carriage and the landing chassis of the aeroplane are separate, 0 being the supporting frame of the ordnance and cl the landing frame of the aircraft. 6 are the motors, f the hulls. In Fig. 3, the arrangement of the three hulls can be clearly seen. The aeroplane has two hulls on either side, the two motors 6 being arranged in front while the persons carried are seated in the short central hull.

It is immaterial as far as my invention is concerned whether the gun be pointed forward or rearward.

When the aeroplane is being used as a hydroplane, the arrangement must be modified accordingly and floats provided instead of the landing chassis.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for Ohvious modifications will appear to a person skilled in the art.

I claim:

An aircraft comprising a hull, a landing gear and a field gun and field carriage and a field gun and field carriage mounted underneath and rigidly connected with said on said aXle between said Wheels. hull with the trail of said field carriage In testimony whereofI affix my signature. raised slightly above the ground.
