Be it known that I, GARFIELD nfwoo a citizen of the United statesyi'residing at usefullmprovements in Automatic :Bailers; off'which the following-jis a specification,

Detroitfln the countyof Wayneand State of Michigan; have invented certain new and reference being had therein to the 1 accoinf panyingdrawings."

fo'r the automatic bailing of vesselsfwherein the suction produced by the passage of the y I hull of a boat, througlr water', particularly, at" high speeds, is"utiliz'ed toldraw bilge water from the through a bilge openingwhich is usually provided with a hood adapted to incrleas'ethe suction andghas usurf ally been also provided with-1a valve "for I With suchjdevic'e's' aslhitherto usech it'has the closing of the said bilgeopening'when the boat is not inim'otionn often occurred that'th'e closing of the bilge valves'has been overlooked -aiter'fa boat has been fbroughtto rest; with' the result that water i has entered the bi lg'egopenings sometimesoto such' erttent "that the boat has been sunlg'and it isan' object otsthis invention to provide aniautorn'atic: bailer which will be'quite as effective as those hitherto used5 butwhich is va lveless andis not there- Vfore subject to the disadvantages f referred to, and requires no attention either as to" the bringing of the said bailerxinto opera-* 7 tion or the prevention; of Tleakage' into the y, hull of the boat owlienthe Psaid boat is not,

' hull of 1a vessel,' illustrating the applicain motion. 1 V 1 h A further object is to provide in :the hull V of a boat a siphonic. trap which will operate for the removalof bilge water from the hull of a boat travelling at a, sufiicient speed and which will' prevent the inflow I of watertherethrough to the said hull when the boat travelling at a slow speed or is at rest; a still further object beingto provide as a bilge pipe for the said purposes and in connection with the bilge opening ofthe hull, a pipe connected or "adapted to be connected with the said opening and bent or adapted to be bent in an inverted- U-formation whereby the upper curved por- 5 tion of the said pipe when in position will be above the water-line of the vessel and. i the lower free end of the said pipe extended towa position wherein it will be immersed :in accumulated'bilgewater in the said'hull;

,Similar characters of reference indicate. si1ni1ar parts in both figuresof thedrawr 7' mg. 7 or 1 y v 1 A hulll is indicated as having a bilge opening 2' therein, over which is superimQ 9 situated in such part of the hull as is most desirable for the collection of bilge water which may accumulate therein. lVhere the said pipe is flexible, the leg 8 may be va ried as to position from time to timeto suit different conditions, and in a preferred adaptation of my invention Imakethe said pipe of rubber tubing, although it may be of lead or other such suitable material. as W111 be readily, understood.

1O lndicates an air vent 111 this example formed by'the cutting of the tube, which.

provides a leaf 11 adapted-tobe opened, closed or adjustedto vary the size of'the opening of the vent'where the suction in the pipe is affectedby' the air vent to an extent requiring its adjustment, although in actual practice ;it is usually found that the vent neednot-be so large as to interfere appreciably with the operation of the device.

It. will be seen-from Figure 1, of the draws ing that the height. of the Ushaped bilge pipe'caus'es the'b'ent portion: thereof to extend above the watereline .of the hull so that (inflow; of water through thesaid pipe to, the hull when suction is not effective cannot take place, the water in the upwardly extending leg of 'the pipe descending in level to that oft-he water-line 6; and the 7 provisionofthe vent l0 prevents any tendency Of'fi reversesiphonic action beingset up inthe pipe which might otherwise result in suchreturn of water to the hull.

=Obviously, the device described requires no .valve to close the bilge opening, so that 1t.1s always ready for operation and cannot bilge valves as hitherto known.

The invention also has the advantage of great simplicity and ready'application to the hull of a. vessel as well as adjustment of the bilge pipe to meet different bilge water conditions, and due to the factythat it is valveless there islessliability of the device to become clogged by foreign matter or to get out of order than is the case where the This invention may be developed within the scope of the following claims without departing formthe essential features ofrthe invention, and it is desired that thespecification and drawing be read as merelyjillustra v tive and not in a limiting sense, e-Xcept as necessitated bythe prior art.

o hat lclaim is 1. In 'a' hull having a bilge outlet therein beneath the water-line thereof,,an automatic i bailer comprising a bilge pipe of inverted U- shaped formation extending upwardly from said opening to a point substantially above' 7 the water-line of said hull and then bent vdownwardly sothat its free endis proximate to apart of said'hull subject tothe accumua lation of-bilge water, said bilge plpe having a vent opening in the upper part thereof.

2. As anew-article of manufacture, abilgeu V pipe for the hull of a vessel, comprising i11 verted U-shaped pipe the legs of which are of greater height than the water-line-of a hull with which it is to be u'sedzand one e-ndf of which is adapted to be connected with a; bilge opening in said hull, sa.id pipe having a vent opening intermediate its length,-

whereby said opening is situated abovejthe water line of saidhull, when the pipe is in use, and prevents'the siphoning of waterlinto said hull.

'3; An automatic bailer accordingtoclaimi 1., wherein adjustable means are provided fortheregulating of-the; aperture of said vent opening. 7
