The present invention relates to an outfit p for marine rescue and salvage of sunken ves;

sels and has for its primary object to provide a group Vof boats which may be arranged in such a manner as to eiiiciently and effectively raise a 'sunken vessel and possess means for supporting the sunken vessel so that the same may be brought safely into port.

Another very important object of the in- A vention resides in the provision of a boat with a plurality of beams projecting therefrom beyond one side thereof with pulleys in the beams and the cables trained over the pulleys in combination with winch and op l5 erating means therefor so that the cables may be utilized in raising a sunken vessel.

A still further very important object of the invention resides in the provision of a boat for rescue and salvage purposes of this nature which may be` manufactured at a relatively low cost, may be Aeasily* operated and maneuvered, and is otherwise well adapted to the purposefor which it is designed.

Vith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in, the combination and arrangement of parts as will be hereinafter more fullydescribed and claimed.

"side of the boat.

- ent from an inspection of Figure 1.

Figure 9 is a detail horizontal sectional view through a longitudinal beam.l

Referring to the drawing in detail, 'it will be seen that in my rescue and salvage outfit I utilize a plurality VVof boats 5. I shall -iirst describe one of these boats in detail as they are identica-l except vas will behereinafter pointed out.

In each boat there is mounted a longitudinal beam 6 extendingslightly to oneside of the longitudinal center of the boat and a plurality of beams 7 extending laterally therefrom across the center and beyond the These transverse beams 7 are arranged in pairs and between each pair there is mounted a pair of sheaves Sand 9, the former adja cent the beam'6 and the latter out beyond the side 4of the boats." The beams 7 are braced in respect to each other by means of rods 11.`

Cables 12 are trained over the sheaves 8 and 9 and extend down into the boat to be windable `on VWinches 14; These winches 14 are mounted to rotate with a shaft 15 journaled in suitable bearings 16 and theshaft lihasa chain andv sprocket connection `17 with an engine or other prime mover 18.

The only-difference between the boats is Y 'inthe length of the beams 7 andthe sides beyond which these` beams project and these differences will become'immediately appar In Fig'n ure 1 it will be noted that I use three boats to each side of the sunken vessel 19 with the beams pointing toward said vessel 19. i

The cables l2 are let down and extended under the vessel 19 and tied together by a diver.A Then the shafts l'areibrought into operation and the cables wound on the winches 14 to raise the sunken vessel. When the sunken vessel. has reached the surface of the water I then utilize a plurality of spac ing and stablizing members 20, two for each boat 5. v p

Each member 2O includes an elongated body having a relatively long downwardly directed lateral extension 21 at one end anda relatively short downwardly extending eX- tension 22 at the other end.

A keeper 23 is mounted onthe beam 6 to receive the extension 22 and a keeper 24 1s fixed to the vessel 19 to receive the eXtension 21. The extension 2l is braced in rev spect to the elongated body of the member 2O by means of a rod 25.

lith the vessel 19 supported in this manner it will be seen that the` vessel along with the boats 5 may be readily towed into port.

It is thought that the construction, utility and advantages of thisinvention will now be quite lapparent to those skilled in this art Without a more detailed description thereof. The present embodiment of the invention has been disclosed in considerable detail kmerely for the purposes of exemplication since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. Y

It will be apparent that changes in the details of construction, and in the combination and arrangementot partsmay be resorted t0 without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what zo I claim as new is: Y

In an outfit of the class described, a boat, a beam extending longitudinally ot' the boat adjacent the center thereof', a plurality of transverse beams projecting from oneside oit the first beam laterally out beyond one side otl the boat, said transverse beam being disposed in pairs, sheaves mounted for rotation between the beams of each pair adjacent the oppositev ends thereof, cables trained over 40 said sheaves, a shaft journaled in the boat and having a plurality of Winches thereon on which said cables are windable, a prime mover, and chain and sprocket `mechanism connecting the prime mover and the shaft, and horizontal crossed brace rods secured at their opposite ends to the inner and outer ends ot' the transverse beams and brace rods secured to the outer end portions of the beams and to the adjacent side of the boat.' Y In testimony whereof I aHiX mv signature.

WILLIAM LADD.
