fO K 'fli'e' difference in movement Of the pai' ts the rest for said end, permitting it to hinge downward on the hanger 3.

Upon the lower end of the hanger iron 3 is hinged a hollow member 21, which receives a rear stem 22 on the torpedo and constitutes a means for carrying and actuating a tripping or firing member 23. The pivoted end of this tubular member or holder is seen slotted at 24 to accommodate the hanger iron, and the two are connected by a trans verse pivot pin 25. The torpedo stem 22 is connected to the holder, after. being entered therein, by a shear pin 26, which is passed through registering holes in the parts. This connection is destroyed, and thetorpedo consequently freed, by the power developed by the downward swinging of the torpedo, when its front end is released; and to this end the front edge of the extension of the hanger 3 below the hinge aXis is formed as a cam or eccentric 27, the form' and relation of which to the stem 22 are such that at a predetermined point in the downward swing, at or near the vertical position of the bomb, the .rear end of the stem riding forcibly upon the fixed cam thrusts the. stem downward and outward in the holder, there by shearing off the pin 26 and permitting the torpedo to drop.

The constructions and arrangements for firing at the rear end of the torpedo involve important features of .novelty. There is a detonator 31 capable of setting off the body of explosive in the interior. This detonator may beignited by means of a time fuse 32, disposed circularly, that is to say in an arc, in a disk 33 forming partof a fuse-container secured 011 the rear end of thetorpedo at the base of the stem 22. This container has an arcuate groove 34 in its front face, which communicates with-the rear face by a series of definitely located flash ports 35. At the regions of these ports the covering of the fuse may be removed and quick match conrposition 32 applied to. insure the action of the fuse. )neend of the groove 34 is connected by a radial groove 36 with a central opening 37, through which the fuse is ledto the detonator 31; The fuse container is completed by another disk 33 also provided with a central opening, and which is screwed into a flange 71 on'the front face of the disk 33, a plate 72 of vitreous material being preferably interposed between the two disks, closing .the face of the groove 34. .A flange 73 on the rear end of a copper tube 74 containing the detonator is alsoclamped betweenthe

disks

33 and 33 of the fuse con tainer, the detonator projecting forward through the central opening in the disk 33 so as to enter the'interior of the bomb. The stem 22is united or. secured in rearward projecting relation to the disk 33, and the disk 33 has av central forwardly dispo'sed threaded. boss 75, whereby the entire unit may be secured to the suitably recessed rear end of the torpedo.

On the lower or forward end of the hinged holder 21 is a timing head 38, which is also in the form of a disk of approximately the same diameter as the fuse container 33. hen the torpedo is in the frame, these two parts are held face to face; and one of them is mounted rotatably. Preferably the head 38 is secured. to the holder in such manner that it may be turned thereon with-- out movement lengthwise. Tongue and gL'OO G formations 33", 38 on the disks and 38 serve to prevent entrance of water between them. The head 38 is cutaway or recessed at one side, as at 39; and in this recess is a firing block 40 containing a cap seat 41 and a flash passage 42 to register with any one of the ports 35. The flash passage 42 terminates in a projecting nipple 43 on the forward or inner face of the rotatable head, adapted to enter said ports and'to hold the parts in fixed relation whenonce adjusted. To permit of the adjustment the firing block bearing the nipple or registering projection is mounted on the timing head disk in such manner that it may yield away from the fuse container, while being normally pressed thereto. This is accomplished by connecting the end of the block 40 adjacent the center to the head 38 by means of a transverse pivot pin 44. An ex pansion spring 45 :confined between the block and a bracket 46 on the head urges the block against the fuse container 33, or to a position in which the nipple will enter a port. The ports not in registry with the nipple at any time are covered by the timing head disk 38. A handle 47 projectingfrom the block 40 facilitates theturning ofthe head about the axis of the holder 21 and stem. 22, and the movement of the block away from the fuse container to disengage the nipple. The-nipple-43 is preferably lo cated eccentrically with respect to the chamber of the flash passage, and the front or lower wall of this chamber is formed with a cavity 42 having a vent opening 42", the cavity being in line with the cap 48, sothat when the latter is fired its wadding will be caught in the. cavity and will be prevented from obstructing the nipple.

Thecap 48, which is placed in the seat 41 in the firing block, is fired by a hammer 49, the head of which is secured to the end of a flat spring 50,..which in turn is secured to the bracket 46. The spring 50 is normally not under firing tension, so that there is no danger'ofits being accidentally released and flying against the cap, and in addition the cap is protected by a safety pin 51, which is inserted through holes in the block 40 over the cap in position to prevent the hammer touching the cap as long as the pin is in place. This pin may be in the form of a otte pi -w th d ersendsco n e y icessible'ring handle; 51?,a ndiis held fr'ictiom ally in place and'may be readily ithdrawn: by ;th e" pilot before pulling the laun hing a by he ppinememb r 23, er dfQmf "*ferredg'to asbeing mounted on, and operated by th h lde nhi mber?
