Application filed December 28, 1917. Serial No. 269,327.

To all whom it may concern: 1 'Be it known thatI, WILLIAM H. Wnnrg LING, a citizen of the United States of America, and resident of Harrisburg, in

the county of Dauphin and Stateof Penn sylvania, have invented certain new and use; ful' Improvements in Devices Relating to Ordnance, of which the following. is a specification. v l i This invention relates to ordnance and particularly to means for discharging projectiles under the water without the liability of the water entering the piece from which the projectile is fired or discharged, as for instance where a projectile is fired from a gun of the cannon type.

An object of this invention is to provide novel means whereby the projectile operates a valve which guards an opening in the protecting structure and in the provision of novel means for returning the guard to its normal position when the projectile has escaped, the said movement of the guard being such as to insure its return to the opening prior to the time water can find its way to the protecting structure and this is possible owing to the fact that the water displaced by the discharged projectile is not returned as quickly as the guard returns to its seat.

A further object of this invention is to provide novel means whereby a protecting structure may be applied to guns now in common use by simply threading the exterior of the said guns at their muzzles, it being understood that the protecting struc ture comprising the unit may be detachably applied as stated to the said gun.

Astill further object of this invention is to provide novel means for permitting the expansion of the explosive charge to such an extent as to minimize the liability of damage as the explosive charge when detonated will almost wholly escape with the rojectile and there will be little or no liabl ity of damage to the protecting structure or the elements associated with it.

With the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters denote correspond- Specification er LettersPatnt. f

ing parts in the several; views, and in which I Figure 1 illustrates a view in elevation, partly in section, of a protecting structure applied-to a gun, a fragment of which is shown; i V

Fig. 2 illustrates a view at right angles to that illustrated in Fig. 1;

Fig. 3 illustrates an end view and Fig. 4 illustrates a perspective view of one of the valve sections' In these drawings denotes a gun barrel to which a plate 11 is threaded, the said plate having apertures 11 for the reception of screws 11". A casing 12 has threaded apertures to receive the screws by which the casing is secured to the plate. The casing has an expansion chamber 13 and a partially closed outer end 14. with an opening 15 which is practically the same as the bore of the gun so that the projectile passing from the gun will escape through the said opening.

Formed integral with or attached to the expansion casing is a valve casing 16, here shown as having a head or plate 17 bolted to it to constitute a closure for one side and the said valve chamber has an opening 18 for the escape of a projectile.

Interiorly of the valve casing, there are shoulders 19 and 20 against which the valve sections abut when the projectile forces them from their normal position which is the position they occupy when guarding the opening and the said valve sections constitute a valve when they are in assembled relation to each other. The valve sections and means for operating them are duplicated and hence a description of one of them will suflice as a disclosure of both.

Each valve section 21 is pivotally mounted in the valve casing on pins 22 which extend through the sides of the valve casing or through a plate for closing an opening in the casing and the said valve sections each has a cam 23 on its inner surface which is engaged by the projectile for dislodging the section from its normal position. Each section has apertured lugs 24 to which the shackles 25 and 26 are pivoted, the said shackles being pivotally connected to a piston rod 27 of a piston 28 which operates in a cylinder 29, the said cylinder having an apertured head through which a pipe 31 communicates with the cylinder for furnishing compressed air or other piston actuating media to the interior of the said cylinder.

Fromfan inspection of the jjdrjawing and from the foregoing description, it Willbe apparent that whena projectile leavesthe.
