considerably improved.

which the following, isa specification.

The present invention relates to afdevice by means of which lifeboats swung out from a ships side are held securely lashed to ordinaryf swinging davits, whereby the life saving arrangements on board the vessel are With the hitherto I known devices many difficulties and drawbacks arise owing to. the complicated 'arrangements for keepmg the boats in the r davlts 1n a steady posltion wh le the shlp is ,moving in a highsea. The said drawbacks are obviated by the present invention, where 1 by considerableadvantages are attained;

f The invention is illustrated in the accom- 3 panying drawing inwhich Figure 1 is a side elevational view, and Fig. 2a plan view thereof.

' and 3 a lifeboat which by means of tackle is suspended" from them. From .one' .of the davits, for example 1, projects a fixed arm 4, provided with a blockr5,fwhile the" other.

' blocks 5 and 6, andby-means of a common fitting 13 on the inner gunwale ofthe. lifedavit 2 ata suitable height overithe deckris' furnished with a block 6. Nearthe foot of the .davit 2 there are two guide. blocks 7 and v 58 for each of two flexible lines'9 and 100i steel or other suitable materiahwhich lines,-

asindicated in the drawing run through the boat are joined to. a line 11 led over an d underthe lifeboat 3 which line afterward passes through a fitting 12 near-the edgeof the deck,-from which it is attached to some easily accessible place ofattachmentQ The lines 9'and10.passeach'to their line drum, which bya suitable'gearing device isable with great force-to draw the respective'linesj I taut. Thefitting 13 is so connected with the inner gunwale of the lifeboat 3'that it is pref ventedfrom being detached from the boatin any h y than y b ingliftedout 0-13 its position. l V

With a device'in above description the following advantages 7 are attained: If the line 11 is secured '-:on

board and the lines 9 and 10 are drawn taut accordance with the the boat is prevented inlanfabsolutely etiective way from moving in any directiombesideswhich the davitsthemselves are perfectly steady, because "the line .9 passes through the block 5 on the arm 4 from the davit;1. j r s 2 .Whenjthe lifeboat is hoisted to its highest positionlfwhile the davit'sand'the lines 9, 10

and 11' aredrawn taut, all need, of-further lashings, as well as of ordinary lashing booms is done away with; ith the above described device it is also 'possibleeasily and rapidly to eflect theswinging-out of the lifeboat fromv its in boa'rd position, which isof great importance when the vessel has a list.
