SHIP-FLOATING MEANS.

To all whom it may concern:

Be it knownrthat I, HENRY D. DEAM, a citizen'of the United States, residing at Benton Harbor, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Ship- Floating Means, of which the following is T a specification. e i Y This invention relatesto ships and vessels of'all kinds, and has for its objectthe production of apparatus adapted to keep the ship to which it' is attached afloat'when the ship has been injured, or, for any reason, is in danger of sinking. A special object of the inyention is to provide apparatus whichfwhile normally not in position for service, yet maybe quicklyplaced in position;' and also for" providing operating position when desired. Otherobjects of the invention will be apparentupon a consideration of the drawings and the descrip tion thereof. 3

Of the accompanying drawings Figure 1 is vertical sectional view. of a portion of the side of a vessel, with apparatus attached theretopwhrchbmbodies features of my invention. Fig.2 is a similar view with part of the apparatus in place andin condition tc prevent' sinking of the vessel. Fig. 3 is a similar view with other elements in use.

Figs; 4 and 5 are enlarged detail views of a portion of the apparatus shown inFigs.

land 2; and Figs. 6 and 7 are enlarged detail views of the means for operating the ship floating mechanism. And Fig. 8 is an elevation'of' a complete unit in use.

i The general method which I have invented to prevent sinking 1 of the vessel is an improvem'ent on the inventionillustrated and 3 described in an application for a patent, j

Serial No. 117,253, filed by William Schneider, Aug. 28, 1916, in which bags are provided which may be fastened to the side i of the vessel and may. be filledwithfair, or 3 other suitable gases,"so that the buoyancy of i thebags, taken in connection with such buoyancy of the vessel itself, asmay exist,

would besufficient to float'the vessel. The apparatus which I use comprises a large normally, are supportednear theupper por- 131011: of the sides of the vessel in anyflsuite able manner, as is. indicated in Fig. 1. A

prefer the bags to be of sufiicient length to reach when distended a very material distance down the side of the vessel, andto ible material whichnot only is airtight and 1 water proof, but which would not be injured by the ordinary saltwater of the seas." The upper portion of these bags is fixed in-any suitable manner to the upper portion of the sides of the vessel. In this instance I have shown them fastenedby boltsll, and also by plpes 12 which, at the same time, provide' means for passing air or any suitable gas into'the bags when they are to bedistended. Any, suitable means for supplying compressed gas may be provided. I prefer for the purpose compressed air tanks 22- connected to the bags by means of pipes 12.

"Fixed to that portion of the bag, which is the lower portion when the bags are in use, is a hook 13, and fixed to each end'of these'hooks is a cable 14:, which, normally, 7

as indicated in Fig. 1, passes downwardly through the opening 15 in the side of the vessehand around the pulley 16,'which is inclosed inthe Water tight compartment 17. The cable then passes upwardly through the pipe 18 screwedinto the casing 19 of the compartment. Passing out of the upper end of the pipe 18 the cable is wound around a windlass20, and from thence passes over a pulley21, and downwardly, connecting with the upper end of the book 13; and it iSalSo connected to the bag by the con nector 25. i I

Any suitable means may be provided for operating the windlass 20. The means which I prefer are "hereinafter described.

The cableis prevented from slipping on the Windlass in any suitable manner; and an inspection of Fig. 1 will show, that, when the indlass is rotated in the proper direction, the hook 13, and hence, the portion of the bag to whichfit is attached will be be drawnLby the cable into the compartment pulled downwardly and the hook will finally 1" sufiicientlyso that when the Windlass is "rotated slightly in thcoppo'site direction the hook will becomef' 'attached to the side of the vessel at the point 23, and "this will firmly hold the hook in place, and,hence, the lower -.hooks vl3 may be released by any suitable means, such asby means of poles with suitabletools on the ends, and the Windlasses 20.-rotated to lift the bags. By suitably connecting the bags to the cable 14: at the pointli25, as the bags are-pulled upwardly they willfoldautomatically and ultimately the sides of thevessel so as to :be

Thelmeans which I prefer for operating' the'varioujs windlasses {comprises a lever 30 which (has aforked end adapted topass over .qthe projecting-axis 31 of the windlass. .By'

When the'bags are allowed to collapse and are elevated therods 28 pass into the vessel throughthe openlngs 29 and-drop downwardly, as indicatediin Fig. 1, holding the sheets: 26 in'place.

Bolts 11' pass throughthebags, and thus hold the upper ends of the bagsjfirmly'in place. And wings36 vmay be :fixedto the hooks 13 to prevent their turning sidewise.

The inflated bags frequentlynqwillrcover small openings which-may be produced in the side of-:the vessel, and prevent the inrush 1 of water therein. .1 haveiprovided additional means for preventing the inrushaof water 5 through openings, of any nature, made, in; any manner, through the. sides ofthe Yes-f buoyancy of the vessel itself. 1 Thesemeahs comprise mattresses .40 which, are to be used connected, in anysuitable marinerftor ex-' ample by means of cords 41,1andhooks-42, to eyes 43; fixedto the hooks 13:;the upper edges of the mattresses being supported chy meansof cords Hand hooks45g-hooked to the upper side of the vessel. Whenever'vit is desired to cover an opening in theside of the vessel the bags-1 0 oppositetheo-pening are lowered "in the usual manner, and sheets ormattresses 40, fixed to the hooks 13 which are associated.'with f suchbaigs, areloWered,
