The rims j of the piston are designed to enter the recesses l of the eastingl when the. piston is niort-d to its extrenie forward position. 'l'hus these riinsand rcee.-.-'es forni dadi-pots to cushion and liniit the forward num-nient of the piston when the torpedo is discharged. vl'iarh piston has f two forwardly extending piston rods li, li,

and these rods extend l'roin diainetrically E opposite points slightly to one side of the vertical plane of the center of the piston. the'turntable 1S is a casting l?, 'having a base portion 1" and two parallel sleeve nieinbers lf2 which are connected to the base portion l1" by webs f and also connected to each 1 which it is connected to the said base portion, said llange surrounding an opening l formed centrally inthe base` The shaft (j extends downwardly through bearings tj' and G2 respectively in thc heads C and C? of the tank or ortun C. Gland rings y surround the shaft and lit into stalling Vboxes formed in the bearings G' and G2 to prevent iside, and with a hollow sirengtheninerib' the` escape of air from the tank or drinn.

'that portion of the shaft which is within the tank is. provided with a series of perforations g through which the air iii the tank passes into the shaft and thence to the torpedo tubes, as will be explained later on.

A torpedo tube H is held at its forward end in each of the sleeve members F2, and each tube has its: rear end closed by a head H. In the forward end of each sleeve nieni` ber and abutting the end of the tube therein is fitted :i cylindrical casting l, which is provided with opposite segmental recesses l foi-ined by concentrically arranged flanges l2 that project lroni an inwardly extending llange l'' orined at the front-end of the casting. lhe llange l3 of each casting has an annular forwardly extending llange z' which carries a packing-ring z" that snugly fits the torpedo to provide :i water-tiifht joint to prevent any water entering the tune when the torpedo is in position, and when the apparatus is installed upon a submarine boat.

forcing them to the forward ends of the tubes. A torpedo is then lowered (preferably by means of a'derriek) and adjusted into alinein'eiit willi either one of the tubes, the lugs upon the upper and lower sidesof the torpedo are then -titled into the slots in to those below the deck of the vessel by an the :shoes L and the torpedo pushed haelt into the tube until the lios of its tail enter the slots formed in the ring ot the piston.

come into close contactv with the. packing strip carried by the inwardly projecting tiaiige of the casting Iland an air tight joint 4 is secured.. The nipple h5 is then connected by a hose extending from a suitable pump to the'ins'ertion ot' the torpedo into the tubethe tripping link L, for trippingthe start- 'ing lever of the propelling mechanism of the torpedo, is elevated into a recess formed in a in the torpcdovtube, and after the torpedo has reached its rearniost position, the link is f allowed to drop down into engagement with the torpedo in front ot the tripping lever, with which the latter will engage when the torpedo is ejected. 'lfhe operation justdescribed is then repeated in loading the remaining tube. alter vwhich the tubes are :swung around to a position parallel with the longitudinal a, is of thel refs-e1. when they and the torpedoes will be completely within.

the housing, in which position the safety catches or nose portions of thc lever Q will be brought into engagement with the segmental locking bar and the leyers thereby prevented from being operated. so long as the tubes are within the housing. The doors of the housing are then closed to completely incase and protect both the tubes and thc torpedoes.

.lVhen it is desired to discharge-om or both of the torpedoc-4,o the tank is charged with air, the doors of the housing are iirst lowered. and the tubes then swung around to either sident-the ves-cl from which the torpedoes areto be lisehai'ged. 'l`he initial movement of the tubes will cause one of the nose portions ol" the levers to ride up on it block R and the other le'vei` to be discn i gaged from its block. thereby freeing only .one of the levers: and as the tubes are t'urvated th(- moment the command given. but '65 the other lever will push its block around in indicator hand g3 carried by the lower end of the shalt (ci and which operates around f an indicator dial i' projecting from the ring R25) the lever of the rear or after tube is The air in the tube is then released through a izilved nipple screwed into the head of i .the tube H. The torpedo is then piished ari ther into the tube until the sides thereof pulled down. which opens its valve and allows the air to escapeinto the rear end of the tube and push the piston outwardly causing. the shoes to engage the lugs if and 15 of the torpedo and forcibly eject the torpedo. During the i'irst movement of the torpedo, the tripping lever controlling the propelling mechanism. will be set,Y an( the string holding the propeller at the nose ot' the torpedo will be broken, and upon further movement the sides ofthe torpedo-will strike against the supportingr rods for the lower aria and knock them from position, which will permit the said arm to drop down out of the way and avoid any possibility of its fouling the torpedo. Thus, itwill be seen= that the said arni is held in a true horizontal position until the lower guide Shoe has travplate /r which surrounds an opening formed i its binding in the slot ot' the arm, thereby v permitting it to slide freely in the said slot. 'ln order that the lower arm may drop down as described, the lower rods are made in sections and connected together as shown at, :c Fig. l0, which permits the rods to break and their outer'cnds 'lrop down with the said arms. A

By reference to Fig. G it. will be seen that the segmental bar S' is of such length that it will be necessary to revolvethetuhesthrough an are oi il() degrees tocilher side ofthe longitudinal central line of tltcir normal o'r inactive position. which thus faves t() degree.` ahead aud astern where it will be impossible to discharge the torpedoes. ma? :Iii arc ol' lill' degrees on either bi'oadside of the vessel' through which the torpedoes may he discharged. thus avoiding all danger ol' thc accidental discharge ofthe torpedoes when the tubes are iii such position that the torpedoes would be liable to come into contact with the deck connections ot' the vessel.

Should it he desired to slowly remove the torpedoes from the tubes. withoutI 'fear ot' tht` danger incidental to the use of air. l provide means whereby they may he withdrawn from thc tubes by hydraulic pressure, and to this cud l connect a hose'to the nipple /r and thcu force enough water into the tubes until sufficient pressure has been brought to bear upon the pistons to force them torg wardlv and gradually push the torpedoes from the tubes. The tubes ll are' provided with drain cocks /1 by which the water thus` forced into the tubes may be withdrawn'.

haring a stud boltv X', Fig. 9, swiieed tlierein, and arranged in, vertical alineinent with the center of the turn-table E and connected to a bracket carried by the casting i? at the top thereof'.

all the strain being iniposed upon the turn table when the tubes are revolved.

Fromthe foregoing it will be seen that I provide :in exceedingly simple apparatus that is equally adaptable for use upon surface or submarine torpedo boats, and When installed upon the latter the housing U will protect that portion of the mechanism 'rranged above the deck from the strain iniposed thereon by the movenient of the vessel through the water, and by the currents, which w nld be apt to injure the gearing or other parts of the mechanism.
