8 Claims.

This invention relates to a bomb ejector and it is one object of the invention to provide an ejector adapted for use upon air craft for bombing ground troops or other targets or upon boats for ejecting depth bombs when attacked by submarines.

Another object of the invention is to provide a device of this type having a number of barrels or tubes from which bombs may be simultaneously ejected by means of a single ejecting mechanism.

barrels.

Another object of the invention is to so mount the barrels that they maybe tilted vertically to angularly adjusted positions and also allow the device to be swung about a vertical pivot to adjusted positions.

Another object of the invention is to guide movement of the bombs through the barrels and, in addition, prevent the bombs from prematurely sliding out of the barrels when the barrels are tilted to depress the muzzles.

In the accompanying drawing:

Fig. 1 is a side elevation of the improved bomb ejector.

Fig. 2 is a sectional view taken transversely through the barrels on the line 2-2 of Fig. 1.

i 3 is a sectional view on the line 3-3 of Fig. 1. i

Fig. 4 is a perspective view of a spacer placed between bombs. I

Fig. 5 is a perspective view of a bomb to be discharged from the gun.

This improved gun has a plurality of barrels I and, while three have been shown in the drawing, it is to be understood that any number desired may be employed. These barrels extend in side by side substantially parallel relation to each other and are held in place by welding, as shown at 2 in Figs. 2 and 3. The welds for holdin the barrels to each other may extend the full length of the barrels or a number may be provided in spaced relation to each other. In the preferred arrangement, the barrels are disposed as shown in Figs. 2 and 3, with one barrel resting upon a pair of lower barrels and disposed over space between the lower barrels.

To support the barrels, there has been provided a carriage 3swiveled to a base I so that the carriage may be swung above a vertical axis and the barrels pointed in. the desired direction. Standards or brackets 5 extend upwardly from the carriage in such spaced relation to each other that the barrels ma be disposed between the standards and, at their upper ends, the standards carry bearings 6 to receive stub shafts i projecting outwardly from the lower barrels. The barrels will thus be mounted for vertical tilting adjustment and may be disposed at a desired angle when disdischarging bombs. Arcuate arms 8 constituting quadrants are secured against outer sides. of the lower barrels and extend downwardly and forwardly therefrom with their lower portions passing through openings 9 formed through the standards. These arms have scale markings l0 upon their outer side faces for observation by a crew member when tilting the barrels to adjusted angle and set screws II are provided to engage the quadrants and secure the barrels in a set position.

The barrels are loaded with bombs l2 which are fed into rear ends of the barrels one after another to be shifted forwardly so that they are successively discharged from front ends of the barrels. Discs l3 are placed between certain of the bombs and are formed with arms or tongues H which project from the discs radially thereof and pass through slots l5 formed longitudinally of the barrels the full length thereof. While discs have been shown between certain of the and omitted between other bombs, it is to be understood that a disc may be placed against the rear end of each bomb as it is fed into a barrel. The slots l5 are so located in the barrels that the tongues projecting through the same may hav their end portons overlapped, as shown in Fig. 2, and thus permit the tongues to brace each other and also permit the bombs in the three barrels to be simultaneously shifted longitudinally of the barrels toward front ends thereof. Ribs l6 extend longitudinally through the barrels to guide movement of the bombs and engage in notches ll formed in heads l8 at rear ends of the bombs. It is necessary to prevent the bombs from accidentally or prematurely moving out of front ends of the barrels when the barrels are depressed and to .do this, spring strips I! are mounted in the barrels. These strips extend longitudinally of the forward end portions of the barrels and the bombs cannot move past said springs unless forced forwardly.

In order to shift the bombs forwardly through the barrels there has been provided discharge mechanism consisting of an endless mover 20 in the form of a sprocket chain extending longitudinally of the barrels under the same and trained about sprocket wheels 2| which are rotatably mounted on shafts 22 supported in bearing arackets 23 depending from the lower barrels. The lower flight of the sprocket chain also en loses a sprocket wheel 24 carried by the shaft )f a motor 25 mounted on the carriage 3 and when the motor is running the sprocket chain will be moved in such a direction that its upper flight moves forwardly and arms 26 carried by and projecting upwardly from the upper flight of the chain will engage the arms or tongues H of the discs l3 and move the bombs forwardly through the barrels. The bombs will thus be successively ejected from the ends of the barrels and drop upon a target over which the air craft is flying or drop into the water OVer or close enough to an attack ing submarine to sink the submarine when they explode.
