Application filed August 21, 1915. Serial No. 46,674.
To all whom it may concern Be it known that LBENJAMIN B. LEWIS. a citizen of the United States, and a resident of the city of Bridgeport, county of Fairfield, and State of Connecticut, have invented certain new and useful Improvements in Guns and Projectiles, of which the following is a specification.
My invention consists in certain peculiarities of construction in a gun for the discharge of projectiles, in combination with a projectile of a peculiar formation, and es pecially adapted for use in connection therewith. Special provision has been made for its use in such vertical direction as may be called for to meet the exigencies of submarine warfare as at present carried on.
More specifically the object of my invention is to provide a gun which shall be light enough to be safely mounted upon a vessel of a comparatively small size; but which shall at the same time discharge a projectile with a sufiicient force to pierce the shell of a submarine even at a considerable depth beneath the surface.
To meet the difiering .phases of such submarine combat I also provide a method of mounting by means of which a discharge may be made at varying angles laterally from the directly vertical and also longitudinally, both forward and aft, at any lateral elevation.
In the drawing Figure 1 is a sectional ele vation of the gun. and projectile when loaded, preparatory to the discharge. Fig.
2 shows the gun mounted and in a vertical position on the side of a vessel. Fig. 3 is a sectional view on the line AA of Fig. 1. Fig. 1 is a detail of construction of breech piece, in sectional elevation, showing an igniting mechanism for use in connection therewith. Fig. 5 is a' plan view of the same. Fig. 6 is a side elevation of the mounting mechanism bolted to the deck of a vessel. Fig. 7 is a plan view, partly in section, of the part shown in Fig. 6.
I preferably employ a collar made of a soft quality of metal, as compounds of lead or aluminum. Thisv collar forms an important operative feature in the practical working of my invention. A suitable degree of hardness in the material of which it is composed, in conjunction with the depth of the thread with which it is screwed onto the projectile tube, serving to regulate the amount of pressure required to strip the screw threads of the collar and thus to impart the required initial velocity needed for the projectile. The explosive charge 19, preferably of a slow firing quality, is contained within the tubular projectile 14.- open at the top. -Detonator 20 is placed with its exterior circumference resting upon the end of the projectile tube and within the hollowed out chamber 13 of the breech plugs interior; detonating rod 31 passes through the breech plug vand makes contact with detonator 20 directly over the wall of the projectile tube.
In Figs. A and 5 is shown a hammer and device for actuating the same so as to produce the proper degree of percussion needed for the firing mechanism. In this 21 is an self, its sides parallel with those of the central raised portion of the breech block.
Within the slot is pivotally mounted a hammer 22, having its outer extremity making operative contact with the end of detonating rod 31. A spring 30, fixedly attached at its outerend of the breech block, bears at its opposite extremity on the rear of the hammer. A sliding pawl 25, having a rectangular end 26, making operative contact with indent 2-1 of the hammer shank, and having a shaft 27 passing through a hole 28 in the breech block, has upon its exterior end an operating spring 29.
- The operation of this form of firing mechanism is substantially as follows :lVhen by spring 30 upon the end of detonating rod. 31, resulting in an explosive discharge of the projectile.
I do not limit the scope of my invention to its use in connection with the precise form of detonating apparatus here shown, as a blow on the projecting end of the detonating rod by means of the gun hammer and trigger in ordinary use suitably in stalled within the breech block would be similarly efiicacious.
The combination of parts made use of in mounting the gun may be specified as follows :A band 32 is fixedly attached to the gun tube. Trunnions 33, preferably integral with the band, rest in bearings 34? of a trunnion holder 34, longitudinally oval in its structure and having a shank 35 rotatively mounted in bearings 38 of gun base 37, said base being securely bolted to the deck of the vessel at suitable points as indicated by the numerals 39 of the drawing. A collar 36, fixedly attached to the outer terminal of shaft 38 serves to retain the same in operative position within the bearing of the gun base. The lateral movement of the gun tube within the trunnion holder is indicated by the dotted lines of the drawing shown in Fig. 6. It 'is evident that the gun, at whatever lateral angle it may be placed may be readily turned longitudinally, either fore or aft, by means of power applied to the gun head, thus causing a par: tial revolution of the trunnion holder within the bearing 38 of the gun base.
I am aware that the tubular projectile, opening pos'teriorly into the firing chamber and containing an explosive charge has been previously made use of in a certain class of firearms in which a funnel-like expansion of the end of the projectile tube fitting into a similar shaped expansion of the gun barrel where it enters the firing chamber has been utilized as a means of retaining such projectile imposition. Frictional c0ntactmore especially in connection with the ordinary rifled barrel'has also been largely depended on for maintaining such projectile in a relatively fixed position within the gun tube. When, however, a gun tube of smooth bore is to be employed in connection with an equally smooth tubular projectile, more especially when a vertical position of the firing piece is necessitated as at times in submarine warfare, some more definite means of retaining the weighty projectile and also of regulating the initial explosive force of the discharge becomes essential. This I accomplish as previously stated, by means of metal collars of differing degrees of hardness and using therefor for the most part, the softer the mine-such screw-threading being forci-.
bly stripped at the moment of explosion.
M improvement, as may be seen, consists in making use of a collar not integral with the projectile, but forming a separate unit of the combination, and which may be readily removed and another substituted in its place whenever a differing amount or quality of the explosive charge may require a less or greater degree of holding tension for obtaining a suitable initial velocity of discharge in the projectile.
I claim:
v1. A gun tube enlarged at the breech the enlargement forming a shoulder around the gun tube, a breech block closing the end of the enlarged portion, a tubular projectile closed at its outward end, the breech end being open, a removable collar screwthreaded upon the breech end of the projectile tube and resting upon the shoulder of the gun tube enlargement, an explosive charge within the tubular projectile and means for firing the same.

I
