This rod is coupled to a rocking lever the superstructure 7 of the boat. The full 23, from the upper end of which a rod 24: ex-

tends to and is connected with an operatinghandle 25. It may be said here that this handle, as seen in the detail views Figs. 7 and 8, is fulcrumed at 26, has a stud 27, which plays in a curved slot in a bracket 28, and a clamping-nut 29. The movements of the handle 25 are controlled or retarded by'a dash-pot device 30. The dash-pot device is omitted from Fig. 8, which is a view from the left in Fig. 7, and this dash-pot device is seen in section in Fig. 7.

The above devices serve to control the valve of the cap-operating engine. On the movement inboard of the piston-rod l0 for opening the cap 3 a fulcrum-block 31 thereon takes under one arm of a rocker 32, pivotally mounted in or ou an arm 33, fixed on a rock-shaft 34.

In order to make clear the operation of the locking and unlocking device, it will be best to explain rst that on the firing-bar 18 is a boss or collar 35, which has in it a bolt-socket 36. Mounted in bearings above this socket is a spring-bolt 37, which tends to engage this socket normally and automatically lock the firing-bar against rotation, and it does so lock it while the cap 3 is closed. This bolt 37 is coupled bya link 38 to a lifting or withdrawing arm 39 on the before-mentioned rock-shaft 34. Now when the piston 9 moves inboard for opening the Cap 3 an inclined face on the fulcrum-block 31 moves under the outboard arm of the rocker 32 and merely rocks and sets the latter Without actuating the bolt 37 to unlock the tiring-bar 18. However, on the screw-threaded inboard end of the piston-rod 10 is a coned wheel-nut 40, which when run or driven outward (or toward the cylinder 8) takes under the inboard arm of the set rocker 32 and, acting through the latter as a lever, with its fulcruln on the block 31, rocks the shaft 34 and withdraws the bolt 37 from the socket in the collar 35 on the tiring-bar, thus freeing the latter, so that it may be operated; but unless the block 31 is under the outboard arm of the rocker 32 the operation of the wheel-nut will not withdraw the bolt 37.

As a precaution against the shifting of the valve 20 of the operating-engine during the expulsion of the torpedo the rod 22, which operates the valve,has a dat portion 22,which plays through a fixed guide 41 and has in it a socket or aperture. This latter is brought into register with a bolt 42, slidingly mounted in the guide 41, when the cap 3 is open, and said bolt is coupled to an arm 43 on the rockshaft 34. Consequently when this shaft 34 is rocked in a manner to withdraw the bolt 37 and unlock the firing-bar the bolt 42 will be so moved as to lock the valve 2O against movement until the firing-bar is again locked.

After the discharge or expulsion of the torpedo the coned wheel-nut 40 is run back out of the Way, as indicated in Fig. 1. Fig. 4 shows the position of the locking and unlocking features when the cap 3 is closed and the piston is at the right-hand or outboard end of the cylinder 8, and Fig. 6 is a plan view showing the positions of the locking devices before the coned wheel-nut is driven or run in under the inboard end of the rocker so as to withdraw the bolt 37.

Referring to Fig. 3, which shows the feature best, 46 is a sliding dog carried by the spring-bolt 37 and adapted to play in a guideway in a bracket 44, in which the said bolt is mounted. When this bolt is elevated or withdrawn from the socket 36, as shown in this figure, the jaw of the dog 46 will be moved almost into engagement with a locking-recess 45 in the collar or boss 35 on the firing-bar 18. This is a precautionary device and can only come into play if the piston-rod l0 should break loose or in any way become uncoupled or disconnected from the open cap 3. If this difficulty should occur, the piston 9 would be driveninboardalittle beyondits normal limit, and the fulcrum-block 31 would be driven under the outboard end of the rocker 32 far enough for a second and abrupt incline 31, Fig. 6, on the block 31 to take under the arm of the rocker and cause the shaft 34 to rock, the other arm of the roc-ker bearing on the wheel-nut 40 as a fulcrum. This extra lift of the bolt 37 (which has been already withdrawn by the wheel-nut 40) causes the jaw of the dog 46 to engage the recess 45 in the collar 35, so as to lock the firing-bar, through the medium of said dog, against rotation. It will be seen that this device forms a lock to prevent the expulsion or discharge of the torpedo when an accident or breakage occurs such as would permit the cap 3 to close.

It will be noted that the movement of the fulcrum-block 31 under the outboard arm of the rocker 32 cannot alone effect the withdrawal of the bolt 37 when the cap 3 is opened, as the lever-like rocker will be merely turned on its fulcrum without producing any result. The unlocking must be eected by the wheelnut 40. On the other hand, unless the cap 3 is open and the fulcrum-block 3l is under the outboard end or arm of the rocker the bolt 37 cannot be withdrawn by the wheel-nut 4() alone, as the driving of the latter under the inboard arm of the rocker will simply rock the latter about its fulcrum without produc ing any effect on the bolt. When, however, the cap has been opened and the fnlcrumblock 31 is moved in under the outboard arm of the rocker and the operator has run the nut 40 under the inboard arm of the rocker, thus withdrawing the bolt 37, if the cap 3 becomes disengaged and closes the piston 9 will be driven inboard a little farther, thus causing the abrupt incline 31 to act on the outboard arm of the rocker 32 and by rocking the shaft 34 a little farther thus lift the dog 46 into the locking-recess 45, Fig. 3, to lock the firing-bar against rotation.

I do not, of course, limit myself to the precise construction of the combined cap-operating device and valve-locking mechanism herein shown, as it will be obvious to any one IOO IIO

skilled in the art to Which this invention pertains that it may be varied in some respects Without departing in any material degree from my invention.

Being the first, so far as I am aware, to combine With a cap operating or opening mechanism an automatic locking device for the firing mechanism and means actuated by the cap-opening mechanism for setting the locking mechanism so that it may be unlocked by hand, I Wish to claim this combination or feature broadly and without limitation to any specific mechanism for effecting the object. For example, it is convenient to employ the Wheel-nut 40 as a means for unlocking the firing-valve When the locking mechanism is set for the purpose by the fulcrum-block 3l; but I do not limit myself to this device. The main object is to so set the automaticallylocked mechanism that the firing mechanism can be operated by suitable means only When the cap 3 is open.

Having thus described my, invention, I claiml. A means for controlling the expulsion of torpedoes, comprising an expulsion-tube, a

cap which closes the outboard end of said tube, means for operating said cap, a firing valve or mechanism for controlling the expulsion of the torpedo, an automatic lock to prevent the operation of said firing mechanism, and means controlled by the cap-opening mechanism which sets the said lock so that it may be operated to unlock the firing mechanism.

2. A means for controlling the expulsion of torpedoes, comprising an expulsion-tube, a cap Which closes the outboard end of said tube, a ring valve or mechanism for controlling the expulsion of the torpedo fromthe tube, an automatic locking mechanism for the firing-valve, a cap-operating mechanism, automatic means actuated by the cap-'operating mechanism for setting the said locking mechanism so that it may be unlocked by manually-operated means, and the said means for unlocking the .tiring-valve.

3. A means for controlling the expulsion of torpedoes, comprising an expulsion-tube, a cap Which closes the outboard end of said tube, means for opening said cap, a firing valve or mechanism for controlling the expulsion of the torpedo, a lock Which automat` ically and normally locks said tiring mechanism, means actuated by the cap-opening mechanism for setting the locking mechanism so that it may be actuated to unlock the firing mechanism manually, and means for relocking the firing mechanism automaticallyshould the cap become detached from its operating mechanism.

4. The combination with the hull of the boat or vessel, its nose-piece, the expulsiontube, and the hinged cap for closing the outboard end of said tube, of the tubular guideV 13 opening through the hull of the boat, the piston l2 therein, the link coupling this piston with the hinged cap, the cap-operating engine, having its piston-rod coupled to the piston l2, and means for manually controlling the valve of the cap-operating engine.

5. The combination With the expulsiontube, the cap for closing its outboard end, the firing valve or mechanism controlling the expulsion of the torpedo, and the cap-operating engine, of a rock-shaft 34, a spring-bolt 37, coupled to an arm on said shaft and adapted to normally lock the tiring mechanism, a rocker 32 carried by an arm on the shaft 34C, a fulcrum-block 3l carried by the piston-rod of the cap-operating lengine and adapted to move under one arm of said rocker when the capis opened, and means for actuating said rocker 32 to Withdraw the bolt 37 when the said cap is open, substantially as set forth.

6. The combination with the expulsiontube, the cap for closing the outboard end of same, the ring valve or mechanism, controlling the expulsion of the torpedo, and the cap-operating engine, of means actuated by said engine for automatically locking its valve against movement when the said cap is open and the firing-valve unlocked, means for automatically locking the firing mechanism when the said cap is closed, and means forsetting the last-named locking mechanism so that it may be operated when the said cap is open, the said setting means being automatically actuated by the cap-operating engine.

7. In a device for the purpose specified, the combination with the firing-bar provided With a boss or collar having in it a bolt-socket and a locking-recess, of the double locking device for said bar comprising a bolt to engage said socket and a dog to engage said recess, said dog and bolt being connectedand moving together and respectively arranged to operate substantially as set forth.

In Witness whereof I have hereunto signed my name, this 20th day of February, 1902, in the presence of two subscribing witnesses.
