IMPROVEMENT IN APPLYING FUSES TO SHELLS.

Specification forming part oi Letters Patent No. 33,662, dated November' 5, 1561.

To @ZZ whom, it may concern.'

Be it known that I, ROBERT I. IARRo'rT, of Cold Spring, in the county of Putnam and State of New York, have invented a new and Improved Mode of Applying Fuses to plosive Irojectiles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure l is a central longitudinal section of an elongated shell charged, and having its fuse applied according to myinvention. Fig. 2 is a similar section of the shell without the l'use and its appendages.

This invention is more especially intended for the explosive projectiles of elongated form usually thrown from ritled cannon, and which move with the point forward; and it has for its principal object to make the fuseserve either as a time-fuse or a percussioni"use,.7 as may be desired, the fuse employed being the paper fuse commonly used in shells, or of any other suitable kind, and the use of fulminates being dispensed with. The said invention consists in providing in the metal of the projectile, on each side ofthe hole commonly known as the fuse-hole, ay hole for the reception of the fuse, intersecting or meeting the first-named hole in a transverse section. In connection with this transverse hole for the reception of the fuse, I employ in vthe irst-mentioned hole, to effect the explosion of the projectile by percussion, a movable plug, plunger, or other piece of metal suitably applied to break the fuse when the projectile strikes, so that the tire from the fuse, which is ignited by the iire of the charge of the gun, may communicate with the charge of the projectile; but this plug or piece may or may not be omitted when the fuse is to be used as atime.- fuse.

To enable others skilled in the art to make and use my invention, I will proceed to describe it with reference to the drawings.

The aperture A at the point of the projectile, commonly known as the fuse-hole, has

a screw-thread, a., in its front part, 'for the re-, ception of a screw-plug, B, and has a shoulder,

t, some dist-ance farther back, to serve as a resting-place for the iiange c, formed on the plunger C, which is fitted to the back part of the aperture. The transverse hole D, which constitutes the principal feature ofmy invention, is drilled obliquely to the hole A through the metal on one side of the said hole and into the metal on the opposite side thereof. I prefer to make this hole Drof taper form, and I so arrange it between the position occupied by the screw-plug B and that occupied by the plunger C that the fuse E may be inserted in it and across the hole A, as shown in Fig. l, and that the screw-plug, when home, will just press upon the paper case of the fuse, and so secure it. The fuse E should be left protruding far enough to be ignited by the iire from the discharge of the gun. Before screwing down the plug the space c e, surrounding the fuse between the plug B and plunger C, should be iilled with gunpowder or quick-match, for the purpose of communicating the re of the fuse to thg, charge of the shell, the communication being made through a hole or holes, d, provided for the 'purpose' in the plunger C. XVhen the shell is to be exploded on striking any object, the paper case of fuse need not be perforated preparatory to its insertion in the hole D, for on the projectile being arrested the momentum which the plunger C has acquired will carry it forward against the fuse, which was ignited bythe discharge of the gun, and cause it to crush and break the case thereof, and so permit the re to reach the charge in the projectile. The tube maybe crushed in the same way by the driving in of a plug occupying the position of B, dispensing with the plunger C. Vhen the fuse is to be used as a timefuse, its case is perforated at a' suitable distance from the end for the fire torreach the charge of the shell at' the proper. time. In this mode ofusing it the plunger may be omitted, though its being allowed to remain would not be in any way detrimental to the action of the fuse.

The convenience of being enabled to use the same fuse as a time or percussion fuse will be readily appreciated 5 and another great advantage of my invention is the safety which re- 2.
