I xact description The'object of this invention is toprovide annnproved lgnltion means fora torpedo for sub-mar ne work. 1

' 1 The main'object-of the invention isto prov1de an ignltion mechanlsnrwhich cannot be exploded by-"accidental handling on shipboard or elsewhere, but which can only be I fired, when in the water, and when in the water can only-be fired upon the torpedo striking an obstruction such as the side of .a

In carrying out the invention, I locatethe chemical ignitible when in contact. with- Water, preferablyin a glass tube, from which the air is exhausted, .to keep the chemical in .25 a perfect state of preservation, so that at anytime even months after the completion of thetube, .thei chemical will be ready for ignition as soon as wateris placed in; contact therewith. In some instances I; prefer to place within the tube containing-the chemical gun cott'on to absolutely insure explosion upon the strikingof an object by a torpedo. In the accompanying drawings, -Figurel is asimilar view of atube, in which gun cotton is also inserted. Fig.. 3 is a longitudinal sectional view, partly in elevation, of the end of a torpedo, equipped with my improved mechanism. 'Fig. 4 isa View of the plug of Fig. 3' as it should appear after striking an obstruction. Fig. 5 is a view of a plug of a modified form for use with the chemical and gun powder tube or capsule of Fig. 2.

.As shown in the drawings, the torpedo shell 13 is threaded at 14 to accommodate plug 10.' .The plug 10 is formed with two chambers; a chamberlO having a restricted.

orifice 12 communicating-with a chamber 171 .i having an elongated sleeve 11 open to interior of thetor'pedo, which sleeve is preferablylooselyfilled with gun cotton. 15. The

I insure a tight fit- The plug 7 is formed with a beveled outer end of greater diameter than citizen of. the United States, residing at Brooklymin the county of Kings, city and 1 State of New York, have invented certain pelled plug 7, which extends outside of the plug 10. -T he interior. of-the plug 7 is cenplug 7 is preferably of less diameter than the chamber 16 in the plug 10.

If the torpedojbe roughly handled on shipboard so that the striking plug 7 will be thrown inward, the glass tube 1 will be broken, but the potassium will remain inert On the other hand,if the plug 7, after the submerging of the torpedo; strikes an object, water will be admitted by the aperture or pocket 8, when the plug is in the position of big. 4, partially fill the chamber 16 so that the potassium trally bored to receive the end of a capsule when the tube is broken, will come in con-' tact with the water,- the potassium'will become ignited, generate heat and steam in the chamber 16, which will force a flame of the potassium through the orifice 12 directly upon the gun cotton, explode the same, and ignite the contents of the combustion chainber of the torpedo,

In the device shown-in Fig. 5, in place of ,the orifice 12, the chamber 17, the 'sleeve 11 andthegun cotton 15, I insert the tube or capsule shown in Fig. 2 into the chamber 16 before inserting the plug 7, so that theend of the glass tube (3 will project outwardly from the chamber 16, leaving the bulbous end of the glass tube within the'chamber 16.

In the capsule shown in this figure gun cotton 4 separated by walls of paraflin 5 and .6 from the free end of the tube. and from the potassium, is provided,

In the device of Figs. 5 and'2, the plug T,'

upon being projected inwardly, will strike and break the. bulbous end of the frangible-- capsuleprtube, the-water from the part 8 will ignite the potassium, the flame. and heat ignite the gun cotton 4}, blow out the 6 and the tube,3, and ignite the contents-of,

the combustion chamber of the torpedo,

I claim as'my invention: g "1. The herein described ignitiondevice for a torpedo, comprising a chamber containing a chemical which will ignite in the presence lug a chamber, whereby upon the plug striking an obstruction water will be caused t0 enter the chamber from said pocket, an inclosing tube for said chemical, adapted to be broken upon impact of the torpedo;

:2. The herein described ignition device for a torpedo,comprising a chamber containing a chemi -al whicl will ignite in the presence of water. a protruding movable plug for contact with bodies exterior to the torpedo,
