The present invention relates to bailers which are-used to bail water from aboat. V :The principal object. of the present in vention is to produce an automatic boat such others as may hereinafter appear, the

. various features of the present invention re-v late to certain devices, combinations and arrangements of parts as fullysetforthhere inafter, the advantages ofiwhich willbe readily understood by those skilled inthe art.

The various features of thepresent invention will be readily understood from an inspection of theaceompanying drawings ililustrating thebest form of the invention at present devised, in which,

F 'gure 1 is an elevatlon-showing the bailer secured to the bilge of a boat and locked by a lock-nut in an inoperative position; v Fig.2.is a similar elevation showing the. .bailer held by a yoke in an inoperative position; f V

. Fig. 3 is an elevation showing the bailer in an operative position; o Fig.4: is a sectional elevation showing the bailer in an operativeposition;

Fig. 5.is a plan, and v Fig. 6 is a detail in sectionalplan on the :line 6-6,Fig.- i. Y p -In boat-s, particularly those used for pleasure, the. removal of-ac cumulations off water therein is inconvenient andoftenunv "f pleasant. In order to remove these accumulations or" water through a bailer o crating automatically acylindrical tube Fig. 4) is fitted within a cylindrical opening formed 7 through the bilge or. bottom 8 .of a boat. Thetubei'? is provided with a fiange9 which, is permanently sealed. to the bilge byv four;

screws 1 O (Fig. 5).--

- p Within th tube '7 isl a. cylindrical fspout 11 which isisplined 'to the tube 7 sothat the spout may slide butjnot rotate therein. To this end a pin 12 onthe tube 7 engages a slot v13 in the periphery of'the spout. The. upper part of the'tube 7 is providediwith a "pair of'openings 14: and 15. (Fig.16) which,

are directed vIIrUBI, FINLAND AUTOMATIC}: BAI ER 357,323, and in Finlandflugust 8, 1928.

spectively with openings 16 and 17 formed in the spout 11. The openings 16 and17, which constitute the intake for the spout,

generally towards the bow of Y the boat. p Q 5 Theibottom ofthe spoutll is closed (Fig.

a).. Adjacent the closed end is an opening l8xwhich is formed. by, breaching the wall of the spout laterally. The opening 18,

v which constitutes the outtake of the spout,

is directed generally towards thewstern of the boat.

Vith this construction the closed portion of thespout outside thejboat cleaves'the water when the boat is under forward head- The swirl of the water, whichmoves relatively to the spout, produces a vortex behind the spout or in its wake. The vortex has atendency to forma vacuum behind thespout atfthe'outtake .18 thus inducing a flow of water from the boat through the intake, spout and outtake.v ,Stated in another way, the vortex produces a condition of unbalanced pressure in thefspout so. that thewater is bailed out of the boat by the V atmosphericuair which acts upon the surface ofthe water inthe boat.

- The water bailed out of the boat passes through a check-valve comprisingv a leather diskvl9 (Fig. 4:) secured by a single screw 20 to a grating 21threaded from thetop of the spout 7 and, ther efore, removable from the inside of the boat...

After the water has been bailed out of the ;-boati the outtake 18 maybe housed {within the tube: as shown in'Fig. 1. In order to lock the bailer in its inoperative position the periphery of the spout is threaded to receive a lock-nut 2-2. When the .bailer is in its inoperative position: the. j oint Y between the V 9 lower ends .ot the tube. and spout are sealed 7 by ajvalve23' (Fig; 4:) on the .bottom of the spout which engages-a valveseat 2i on the jbottoniof the tube. Moreover, by manipw lating the nut 22ithe spout may be drawn.

into the tube a variableamount with the re sult'that the area of the intakje openings 16 and 17 may be variedwithoutyarying the V I "area of the outtake '18. whenthe bailer is in operation,' register re-.

1 r Pr id -1a may m n if r elevating the spout into its inoperative position the lock-nut 22 carries a pivoted yoke 25 having an offset portion 26. The offset portion of the yoke may be used as a handle in lifting the spout and may be positioned against the flange 9 (Fig. 2) to hold the spout in its inoperative position. The yoke is used to hold the spout in its inoperative position when it is desirable to interrupt the operation of the bailer temporarily as when the boat stops or is reversed.

While the bailer may be used to'bailthe bilge-water from the boat advantage may be taken of the internal threads onthe spout to couple. a conduit thereto and thus extend the spout to flooded compartments in any part of the'boat.

"VVhat'is claimed as new, is

'1. In'an'automatic bailer, the combination with a spout having an intake inside the boat, an outtake outside'the boat, and acheck-valve intermediate the intake and outtake, of 'int'erfitting tube means perma' nently "fastened tothe boat for slidably securing'thespout,said-spout and means being-relatively movable to one position for housing the outtake in an inoperative position and'having cooperating surfaces to seal the end of the" spout outside the boat when the portion containing the check valve is projected within the boat.

2. In an automatic bailer, the combination with a movable spout having an intake insidetheboatand an outtake outside the boat,'and rigidly fastened'means for secur- "ing the spout to the boat, said intake and outtake operating, respectively, to draw "water from within the boat and discharge 'it'from the boat when the boat is under forward head-way, of valve 'means for preventing the backing-up of water through the spout when the-boat is not-under head-way or is under reversed head-way, and a second 'valve means for sealing the rigidly fastened means to prevent leakage when the bailer is not-operating.

* 3. In an-automatic bailer, the combination with a tube secured to the boat and passing therethroughand provided with a valveseat adjacent the open end outside the' boat, of a spout splined'to the tube havingan 'intake'insidethe boat and a closed endarid an outtake both outside the boat, a valve adjacent the closed end arranged to engage the valve seat when the spout is elevated within the tube and a grating detachably arranged between the intake and outtake and removable from the inside of "the boat. 7

4. In an automatic bailer, the combination with-a flanged tube secured to the boat and 'fpassin'g therethrough and a spout splined to "the tube having an intake inside the yoke pivotally mountedon the spout mounted to cooperate with the flange to hold the spout in a position such that the outtake is housed within the tube.

5. In an automatic bailer, the combination with a flanged tube secured to the boat and passing therethrough and a spout splined to the tube provided with internal and external threads, an intake inside the boat,an outtake outside the boat, a checkvalve threaded into the spout, and a locknut threaded onto the spout, of a yoke carried by the nut mounted to cooperate with the flange to hold the spout in a position such that'the outtake is'housed within the tube.

j6fIn an automatic bailer, the combination with a tube secured to the boat and passing therethrough, of a slidable cylindrical spout'therein having an intake within the boat, an enlarged closed end outside the boat, an outtake adjacent the closed end comprising a breach in that wall of the spout which is directed towards the stern, a detachable grating mounted within said spout between the intake and outtake and removable from the inside of the boat, and

a valve arranged beneath said grating.

7. In an automatic boat bailer, the combination of'a tube permanently seated into the boat and passing therethrough, and a bailing spout slidably retained within said tube and carrying a check valve intermediate its ends, the outer end of said spout having an enlargement cooperating with a seat formed on said tube for sealing the bailer against the entrance of water into the boat between said tube and said spout.

'in a fixed position.

9. In an automatic boat bailer, the combination of a tube permanently sealed into the boat and passing therethrough, a bailing spout slidably arranged therein having an open end within the boat and an enlarged closed end with a valvesurface outside the boat, a valve seat for said enlarged end on said tube outside the boat, and a checkvalve removably inserted through the open end of said'spout.

10. In an automatic boat bailer, the combination of a tube permanently sealed into the boat and passing therethrough, a bailing spout slidably arranged therein, having an enlarged closed end formed with a valve surface outside the boat, a valve seat for said enlarged end on said tube outside the its valve seat.
