SALVAGING Application filed September lvlv present invention relates to an im proved salvaging equipn'ient for use 111 raising); sunken or submerged ships or vessels to the water surface. In carrying out the salvagzin operations for a sunken ship, utter the hi or has been properly located, I utilize a. pair of salvaging or rescue ships ot. suitable (looting capacity, one located at each side of and parallel with the sunken and from the surface vessels lifting hooksand cables are lowered. A diving bell o miationsyand by proper signals from the diving bell to the deck oi? the salvaging ships the lifting hooks are manipulated from the decks of the ships, and caused to he engaged with the walls about holes, as porl'holes in the hull of the sunluin ship, or with other objects on the ship that will support the hooks. in order that the sunken ship may be raised to the surface. A pluralitv oi the or lifting hooks are used along each side of the sunken ship, said hooks being lowered one after another and secured to the hull or other part of the ship, and a supporting. table is temporarilv employed torthe lifting book as it is being attached to the sunken ship. The
manipulati g, adjusting, and control of the operating parts of the hooks are all under control of men on the salvaging ships who a e directed bysignals from theman in the diving; bell. I

In order that the general assembly, or raugement of the ships, and utility of various parts of the equipment may readily be understood I have shown in Figure 1 the sunken ship S assumed to be resting on the bottom of the river, harbor. sea, or ocean and the two salvaging vessels A and B are in position for supporting the hoisting, mech- .llllSlll bymeans of which the various submarine devices are lowered and raised as well .as for supporting the hoisting machines for the sunken ship. The two salvaging ships are tied together by a suitable number of transversely arranged, spaced beams 01 girders or trusses '1 that span the space between the salvage shipsand above the sunken ship and these trusses are pivotally connected, at P with frames F of the salvaging ships in such manner as to permit relative movement of the two salvaging ships on the water surface, it being understood of course that the two salvaginn" ships are anchored in suitable manner to prevent their displacement from opera-- and provided with proper telephonie connections, signal apparatus. and other neces sary equipment for communicating with the men on the deck of the salvaging ships, lowered from the deck of the suspending ship in position for use ad jareut the sunken ship.

A cable cable causes thedruin tot-urn on'the-e screw bar of the holder moving said screw "bar to thewright or leftin Figurew l. Thus the holder maybe shifted to the left 'as indicated in Figure 4 to move thehook or its born 5 to the lifting position of Figure 5, and when 'theilifting pull isappliedto cable '2, the
hook is lifted to operativeposition inFig. 5.

For turning the horn to'hooking position of a Figure: 51 employ a 'cable;36, and apulling device on the deck of the salvaging 1 ship. The cable' is passedfunder a guide pulley '37 on one side of thetable andconnected-to the lever 7 of thebiwhingfand as'theiguide pulley is below the lever, a pull on the cable 'or cord depresses thezlever and elevates the horn as in Figure 5; I 'Atter the hook has been properly placed and its cableQ is'secured, theholder is withdrawn "from thevbracketsi25, and then the table 29 is lifted: by'usingthe hoisting cable 3.1, as indicated in Figure 5, after which the table and another hook are lowered and the succeeding hooks are placed in position, the table being alternately lmvered an d elevated and the holder being OPCl'iliCLl tor the placement of the hooks, s s
Atlter all of the hooks have heenplaeed at the opposite sides oi? the sunk-en ship, the hoisting nierhanism: tor the various Cables 2 are operated and the hooks form a. cradle for lifting the ship on an even keel. ll hen the ship has reaehed the surface and is floated, the numerous hooks are disengaged from the portholes and gathered on shipboard for future use. i i
Having thus fully described my invention, what I claim as new and desire to secure hy Letters Patent is 1. A salvaging equipment for use with a sunken ship and a pair of salva ing ships comprising transversely arranged trusses having pivotal connection with the salvaging ships and spanning the s race over the sunken ship, hoisting eahles suspended from said trusses and hooks at the ends of said Cables, means for holding the hooks and means for moving said holding means to bring the hooks to operative relation tolhe sunken ship. i
2. A salvaging hook for use as described comprising; a clutch bar, a horn having a non-slidable bushing pivoted on the har,a
i swivel har.
swivel bar and e'lutoh links onthe swivel ha r for supporting the clutch bar, and means for seleetively moving said links to lock clutches for rigidly holding the bushing and 3. The combination with a swivel bar and a pair of laterally movable eluteh links, of a clutch har suspended in the links, a pivotal, non-slidable clutch hushin between the links and provided with a nook-horn, and means for moving said links to clutch engagement with the bushing.
il. The combination with a svxivelhar and a pair of laterally, movable clutch links slidahle on the bar, of a clutch bar suspended in the links and pro *ided with screwthreaded ends, a pivoted clutch bushing on the eluteh bar between the links, a hook horn on the bushing, and a pair of rotary drums on the threaded ends and operating means therefor for moving the links into clutch engagement with the bushing.
5. T he combination with a salmging hook and its suspending cable, hraekets on the hook and asupporting yoke for engagement with the brackets, of a screw har rigid with the yoke, a support and a hearing sleeve thereon for the serew bar, a non-traveling nut on the screw bar, and ineanseonneeted with the table for anchoring the nut.
In testimony whereof I ai'lix my signature.
