LIFE-SAVING AND SALYAGING APFARA'IUS FOR USE WITH MARINEVESSELS.

Application filed October 24, 1927. .Serial No. 228,319.

My present invention relates to improven-ients in lire-saving and salvaging apparatus for use in marine vessels, and it is intended not only toprovide means for-locating the position of the sunken vessel after it rests on the bottom of the sea, and also means for mounted thereon, with the floats floating on the top of the water. 7

Figure 2 is aplan view of thepart of the ,apparatusthat is permanently attached to the ship, andwhich isuse dg, both in housing the l'loatand in providingholding means which maybe grappled fromthe surface of the water.

Figure 3 shows asectionaalong. the lin 3+3 of Figure 2, and shows the float in dotted lines.

Figure 4: shows a centralverticalse'ction through the float, parts being shown in velevation.

Figure o shows a 55 of Figure 4 andlooking down, parts being shown in elevation, and the wirecable being omitted from the reel.

Figure dis a detail View partly in section of one of the brackets and rollers used in suspending the cable drum, so as to permit the same to rotate aboutits transverse axis.

Figure 7 shows a section alongthe line 77 of Figure 6 and looking in the direction of the arrows. I

Figure 8 is a detail showing, in side elevation, the cable drum as detached from the apparatus; and

Figure 9 is an enlarged sectional view 7 showing the pivot on which the yoke carrying the cable drum is suspended.

Referring first to Figures 1 to 3, the vessel shown as submerged in Figure 1 is provided near the bow and stern with a skeletonvfrarne section along the line:

work A rigidly attached to the vessel in such a way that the grappling irons may be attachedjto it, and the vessel may be pulled up bodily from its position on the bed of the ocean, as -,will be hereinafter more fully-described. i a i This skeleton frame work comprises a number of beams preferably in the form of T-irons A which are l radially disposed about ahollow central hub B secured to the deck C ofthe ship. The outer ends'ofzthese beams project downward as shown in Figure 3, and; terminate in heavy boltsA which preferably pass down tot-he keel as shown 1nF1gurel, or are otherwise .SBCu BdtO the structural'parts of the ship so as to forma structure sufiiciently strong to permit the shipeto bepulled up bodilywhen the necessary lifting cables are attached to the structure.

The vertical portions ofthe beams A: are

preferablyattached to the flat ring D which i 'is secured to thedeck of the ship in any vconvenient way as by the bolts d. "The radial portions ofthe beams A' areperforatedto receive thehejavy wire cables E which are spaced apart asshown in Figures '2- and B and permitthe passage therethrough and the engagement therewith, of suitable grappling hooks or' irons, not shown. The radial portions of thesebeams A" and the float 'Fawhich mustbe of quite a large size .tossecure the necessary displacement of water'to permit the floatrto rise to. the surface with the load of material carriedtherethefcables E provide aqnest or housingfor by, which load will be hereinafter more fully explained. i

Details of the ,fioat and partsflcarried therebyareshown in Figures 4 to 9. Referring specially to Figures 4 and 5.]the float is provided. with ajcentral hollowfpor- ,tion lFflexterior to which is the main air chamber' F", and the outer cha mber F The walls oi" these air chambers are provided with braces G to render the same rigid against compressive strains; The top of the float is provided with a cylindrical chamber-H closed by suitable cover H, which cover may be provided with hand holesh closed by suitable caps h. l The bottomnof as the float rises.

cable is attached to the vessel in any conven' this chamber H may be braced with a suitable ring H in cross section in the form of an angle iron as shown in Figure 4:. This chamber 11 provides a space for storage of medical and other supplies, concentrated food, inflatable belts or the like, which may be gotten at after the float rises to the surface as shown in Figure 1. Passing-down through the supply chamber H is thehousing 1 for the spindle J, which spindle may carry at its free end an electric light or a flare or other signalling devices K, which not being a part of my present invention will not be described herein. The lower end of thevspindle J provided with a head J of ball bearings'L may be provided ifdesired,the object being to permit the yoke M to rotate freely on the spindle J. Journalled in this yoke M is the cable drum N, on which the light wire cable 0 is wound. This drum is mounted in the approximate center of the air chamber F which is open at the bottom 7", as shown in Figures 4- and 5, topermit the free passage of the cable 0 The lower end of this ient way as by means of the U-bolt 0 shown in Figures 2 and 3. To prevent the cable from unwinding too fast, the ends of the drum N are provided with brake plates or wings 7% shown in Figures 4: and 8 which will engage the water when it enters the chamber F while the float is rising.

In order to allow the drum to rotate around its transverse axis and at the same time to steady the same as the float rises, I provide a track and bracket arrangement whereby the weight of the yoke and drum,

and parts carried thereby, maybe taken on a series of circular tracks on which run rollers. Such an arrangement is shown in Fig ures l, 5, 6, and 7, where P and P represent brackets or arms attached to the yoke M and carrying near their ends rollers p.

The brackets P and P may be provided with turnbucklss 77 to adjust the attention 'o'f'same if desired. These rollers travel on circular tracks Q, Q and Q supported by bracket P shown most clearly in Figure 4-.

Thus, if the float itself rotates as it rises to" the surface, the downward strain on the on to same, or if desired these may serve as a ladder to permit any one to climb on top of the float and gain access to the chamber H for the purpose of securing the supplies contained therein.

The operation of the devices is as follows:

The skeleton frame A being mounted and securely attached to the body of the ship, and the floatbeing nested in the same with cable O wound up on the drum L and the end of said cable being attached to the U- bolt 0, suppose the vessel to sink.

As the vessel sinks, the float will be auto matically lifted off its seat, and the wire cable 0 will pay out until the float rises to the top.

While the float is still submerged or partly submerged, the water will flow into the bottom of the chamber f and compress the air in the central chamber F and the water will rise therein partly submerging the drum; and the wings N on the drum will churn the water, and serve as brakes to prevent the too rapid paying out of the cable. Any tendency for the float to swing around like a top would not affect the proper paying out of the cable, because the yoke carrying the cable drum will be held substantially steady while the float rotates about it.

Under certain conditions, persons may be saved by clinging to the hand grips R as the vessel sinks; but where the vessel sinks in deep water, such clinging would ordinarily be impossible; but at the same time when the vessel does reach bottom, the front will reston the surface of the water, and these hand grips will serve as safety devices for persons floating in water nearby who can swim to the float and hold on to these grips or can even climb on top of the float, moreover, the supplies in the chamber H may be readily availed of by the persons in need of medical treatment or food, or life belts can be held in same, 7

Obviously the float may carry a flare or electric light, which will be put in operation when the float rises, or the float, may carry abell, not shown to indicate its position in the dark.

Such details can he obviously supplied, but they are no part of my invention, and will notbe further described herein.

Zhave thus described the operation of the devices as a means for salvaging of the crew or passengers, and for locating the position of the sunken vessel. In order to use the arrangement for salvaging purposes, the cable will serve as a guide line to send down grappling hooks or other grappling devices carried by heavy cables, and these when lowered will be arrested somewhere within the skeleton frame from which the float has floated, and when these cables are pulled up, the grappled hooks will engage one or more of the stout cables E. It plurality of hooks and cables may be employed to engage each skeleton frame, and thus sevv eral hoisting, cables maybe, operated, at once by salvaging. vessels.

While I; haveshown in Figure ,1 two of -the sets otapparatus, one atthe bowand the other at the stern of the,-vessel,, it will be obvious that asingle apparatus may be used; but three ormore maybe used itdesired., It will also be obvious that the skeleton frame may be attached to the vesseLin 2 various ways, and that suchv an attachment ,would depend in large measure on the structural design of the vessel itself, so that I, .do not IIIGaILtO, limit the iliventlon. to: the precise construction of apparatus herein shown, and described; nordo I mean to limit the invention to other details ofconstruc- ;tio,n, except. as particularly pointed out in ,the claims. i
