To all who/n it 'IHJL/j (Yo/worm:

in tho accompanying drawings, Figure 1 is o vorticnl section through a fragment of a.- torpedo, showing one mode oi applying tho improved vulvo provided by my invcntion. Fig. 2 is a vertical section of the valve in its closcil )osition. Fig. 3 is a similar section oi the. va V6 in its open position. Fig. 4 is a transverse section through the auxiliary vulvc. Fig. .5 is a. vertical section of the inner shcll removed. Figs. 6 and 7 are olevctions of the auxiliary valve removed. Fig. 8 is an elevation of the tappet or plunger V. Fig. 9 is a section of the inain valve, showing a modification.
Rclorring to Fig. 1, let A designate the l shell of the torpedo; B, the compressed-air reservoir or lloskjC, any usual or suitable filling valve or plug through which compressed air may hc charged into the flask; D, the starting-valve E, the reducing-valve, and F the cnginc or motor, which in 'this case is shown as a turhinc, although nnv kind of engine may he used. From the flask B the compressed uir passes by a pipe (L to the inlet of the valve l), thence by a pipe b to the regulator E, and thence by 11. pipe 0 to the inlet of the nozzle d of theturhinc. This arrangement may of course be greatly varied.
The. prefc-rreil construction of the valve D is shown in Figs. 2, 3, and 4. The valve is host constructed with an outer shell G and an inner shell or hushing H, fixed in place thereinl or example, by screwing up a ring I behind ii Tho shell G is formed with a valve soot qscpnroting its inlct-chombcr ii from its (llrlfillfilgQ-Qllilmile! Within the shell G is a suitable. valvc R, adapted to close against the scat e and constructed as a. piston or plunger moving freely within the shell H, with which itv makes a close working fit, but preferably without any packing, so as to per mil. a slighr leakage post the piston, or any other moans lor slowly admit-ting fluid past the valvc may he uscrl. This vsilvc K is nornmlly held to its scat by the )ressure of a. spring I, whi h is conveniently applied to not against :1. YlIlVP-Slifilll M, the spring being housed in n iubulnr extension G of the shell G, which is closcd at its outer and by a suitahlc cap M. The piston of the valve K when closcil is pressed to its seat by the pressnrc of air noting against its rear face in a chmnherf, into which compressed air flows throu h tho narrow spl ce around the piston.
A (linphragin I is Arranged to be exposed to tho gaccous pressure generated during the firing of the torpedo. It may be arranged as shown in Fig. 1, where it is mounted in an o inning formed in the shell of the torpedo. 'lhe rim of the diaphragm is fastened to a cirwlar shell Q, forming a chamber, within which is inclosed a disk R, which backs the diaphragm, and when the latter is forced inwardly oy .the pressure communicates mo tion to a; pin or valve-stem S, which is connected to an auxiliary valve T. Instead of the diaphragm any other equivalent moving i Prior to the launching the plug C is opened air-pressure leaks aroun the valve K into ,0 and unseats the auxiliary valve T, thereby 5 piston-valve K and permits the pressure in tor E an to the engine, and this flow con- 5 out through the ports 'L g h and be wasted.

part may be provided. The stem S and valve means for holding the valve T unseated. A T preferably are arranged transversely to the little plunger or ta pet V, Fig. 8, is arranged axis of the main valve; but this is not essento work in a suitab e guide or socket V in the tial. The valve T closes against a seat 9, lining-shell H and has a head it in position to 5 which on one side communicates, through a be struck by the piston-valve K in its openport h, with the exterior and on the other ing movement, whereby the plunger V is dis- 7 o communicates, through a port i, with the laced or forced back to the position shown chamber A spring U is arranged to press in Fig. 3. In this movement a shoulder l on up the valve T, the latter being preferably this plunger acts against an incline m, formed 10 constructed as a Iplunger working in a cylinin a recess in the body of the valve T, and

It thus insures that the chamber f behind the main valve shall be kc t in open communication with the externa air, so that no pressure can accumulate in it, and the main valve cannot be reseatcd. At the end of the run, when the supply of compressed air is exhausted, the escape 0 its pressure from the inlet-chamber e enables the spring M to restore the main valve to its seat. Thereupon a spring n restores the lunger V to its original position, thereby reein the valve T and permitting its spring U to c ose it against its seat. Thus the parts are restored to their original position ready for the next operation.
Preferably a hand-operated relief-cock W is provided in order that the st arting-valvc 5 l) may be opened at will, as is required for making an experimental or test run of the engine. To this end, communication is afforded between the (hamberf and the inlet to the cock W by means of a. passage 1), openio ing into the socket or chamber in which the plunger V works.
It must not be inferred from the particularity of detail with which 1 have described and illustrated the preferred form of my init ventioii that I am necessarily restricted to the particular construction herein set forth. My invention is, in fact, susceptible of a wide range of n'iodiiication within the judgment and skill of a mechanic or constructor. F or i example, I am not to be understood as limited to the main valve being necessarily a pistonvalve, nor to the auxiliary valve being necessarily a plunger or tappet valve, nor to the means for retaining the valve open being a tappet or plunger displaced by the main valve.
Fig. 9 shows a modification in which the plunger V is omitted, and instead a tappet stein V is ixed'to the rear f the valve K and carries a project on l, which acts against the incline m in place of the shoulder Z in the construction first described.
What I claim is to admit com ressed air through pipe a to the inlet a" o" the valve. The air-pressure acts temporarily to unseat the valve against the pressure of the sprin M until sufficient the chamber f to cooperate with the s ring and reseat the valve. (See Fig. 2.) T iereafter the air-pressure in the chamber 7, acting iigainst a larger area on the back of the valve than that against which acts the air-press sure in the chamber a,holds the valve presse strongly to its seat. At the instant of firing the gaseous pressure in the launching-tube presses in the diaphragm. as shown in Fig. 5,
roviding an escape for the pressure confined in the chamber f, which accordingly blows out through. the port 71, seat and port h. This relieves the pressure on t e back of the the inlet-chamber c to force back the valve to the position shown in Fig. 3. Thereby a wide opening is permitted for the outflow of air throu h the pipe b to the pressure-regulatinues during the entire run of the torpedo. It is desirable to prevent any further leakage of compressed air back of the valve K, since the air thus leaking past it would simply blow To prevent this, the rear face of the pistonvalve K is made to act a ainst a valve-seat being preferably groun to fit this seat, as shown, so that in the position shown in Fig. 3 The diaphragm 1 remains depressed only while it is subjected to gaseous pressure in the launching tube. Upon the ejection of the torpedo it is released from this pressure, 55 and the valve T would then reseat itself, after which any leakage of compressed air past the main valve K into the chamber f might in course of time develop such a pressure in this chamber as to force the valve K against 60 its seat, and thereby cut off the supply of air to the engine. This might occur efore the l.
