To all whom it may concern I Be it knownthat I, EDWARD W. NnwnLL,

a'citizen of the United States, residing a Pittsburgh, in the county of Allegheny an Y escapes upon detonation of the projectile.

A 1 front end with a member 3.

' atinfilposition.

In the accompanying drawing; Figure 1 is a central longitudinal section of a projectile embodying my invention, showing the primer in its operative position; and Fig. .2 a similar view of the nose portion of the projectile, with the primer in its non-operile my invention may be employed in nnection with a time fuse'controlled projectile, the same is illustrated in the drawmg as applied to a projectile adapted to be detonated by impact.

As ,shown, the projectile may comprise a section of tubing 1 adapted to be attached by I screw threads to the base portion 2 and having screw threaded enga ment at the e nose portion 4 of the rojectile is screwed onto the member 3 an a cap member 5 is screwed into said nose portion 4. p

Mounted within the member 3 and adapted for ion "tudinal movement is a firing lunger 6 ving a forwardly extending ammer portion 7 and arearwardly extendcup portion 8 adapted to contain a carti i dge 9 formed of amaterial suitable for forming an obnoxious gas when ignited.

Forwardly of and in alinement with the hammer portion 7 ,,a primer holder 10containing a .primer 11 is mounted in the nose portion 4. g

In operation, with the parts positioned as shown in Fig. 1 of the drawing, when the projectile is firedand strikes an objeet, inertia ,causes the continued movement of the firing'plunger 8 relative to the projectile, causing the spring ring 18 to expand and permit the outward movement of the plunger, so that the hammer 7 strikes the primer 11 andthe flame from the primer then passes througha central aperture 12 in the hammer 7 tea central aperture in the cartridge 9, igniting the cartridge to produce gas.

To facilitate the quick combustion of the cartridge, openings 13 may also be provided in the member 6,'and the rear end of the primer holder is slotted, so that the flame from the ignited primer 11 can readily pass through the holes 13 to the cartridge.

The flame from the primer also passes through the opening in the cartridge 9 to the usual tube 14.- leadi to the projectile explosive charge 15 and since the flame must pass the cartridge and ignite same before the flame reaches the ex losive charge, it

'will be seen that the gas is sure to be produced before the projectile is detonated.

In order to provide for the prevention of accidental, explosion of the projectile in. handling, etc., the primer holder 10 may be made reversible, so that when transported, the rimer holder is placed as shown in Fig. 2 o the drawing, with a knob 16' adapted to take the blow of the firing hammer 7 in case of accidental forward movement of same.

In order to indicate that the projectile is in an inoperative position, a projecting washer 17 may be interposed between the cap 5 and the nose portion 4 when the parts are screwed together.

When it is desired to put the projectile in operating condition, the, cap 5'1s unscrewed, the primer holder is turned around, so that the primer side is presented to the firing plunger as shown in Fig. .1, the.

before detonation, does away with the use of any charging a paratus.

' Havin now escribed my invention, what I c aim as new and desire to secure by Letters Patent, is I 1. A rojectile comprising a casing, a primer t erein, and a firing plunger containing a cartridge formed ofa substance adapted upon ignition to generate an obnoxious gas.

2. A projectile comprising a casing con- 5 taining a primer, an e'xploslve charge,- and a firing plunger located between the primer and the explosive charge and carrying a substance adapted upon ignition to EDWARD W. NEWELL.
