Similar parts are designated by the same ref erence characters in the several figures. Water closets according to the present invention are adapted to be applied to boats of various sizes and types, and the preferred embodiment li) of the invention is shown in the accompanying drawing and will be hereinafter described in de tail. It is to be understood however that the invention is not restricted to the particular con struction shown since equivalent constructions 15 are contemplated and such will be included within the scope of the claims. As shown in the drawing, I represents a portion of the bottom of the hull of a boat, the hull bot tom sloping longitudinally or in a fore and aft 20 direction as shown for example in Fig, 1 and also sloping laterally or in a direction from the keel to the side of the hull, although it will be under stood that the closet is applicable also to boats the bottom of the hull of which is flat or level, either longitudinally or transversely or in both of such directions. 2 represents the closet bowl which may be of any usual or well known construction, it having an annular channel 3 at its top or rim and apertures 4 leading therefrom to the sides of the bowl for flushing it, the lower or discharge 30 end 5 of the bowl being surrounded by an out wardly extending flange 6 which is preferably lo cated above the lower extremity of the bowl. The closet bowl is mounted on a stand which, 35 adjustable to compensate for the slope of the hull bottom in a fore and aft direction and a slope of the hull bottom in a direction from the keel to the side of the boat, and is also adjustable so 40 that it may support the bowl at different heights above the water-line of the boat in order that the lower or discharge end of the bowl may occupy the proper height with respect to the water-line. The stand as shown in the present instance com 45 prises upper and lower plates 1 and 8 which may according to the present invention, is universally be composed of metal castings, these plates hav ing openings 9 and I0 formed centrally therein and having pairs of segments l I and l2 cast there on or otherwise ñxed thereto at opposite sides 50 of the central openings in the respective plates, the pair of segments on one plate being closer to gether than the pair of segments on the other plate so that they may fit between them. Each of the segments Il on the plate l is provided 55 with a series of holes I3 which are preferably spaced equi-distantly, one of these holes being con centric with the arcuate periphery of the respec tive segment, and each of the segments l2 on the plate Vll is provided with a series of holes I4, 60 2 2,130,954 these holes being also equi-distantly spaced and Bolts ’ “ cure the latter to the scoop and form a water-tight I5 extend through the holes in the respective seg ments Il which are concentric withA the arcuate . bottom of the hull into the plate 35, a lock nut 31 being preferably threaded on the pipe 36 to se one of these holes being concentric with the arcu ate periphery of the respective segment. i.' bowl and being extended downwardly through the joint around the lower end of the pipe. in the segments ¿I2 and serve- to >clamp-together the pairs of I8 segments are also inserted on the plates in appropriate 1 and 8. Loclçf holes“ ing bolts installing the closet» in a boat, the stand may‘be“ mounted with the lower plate 8y resting on the hull bottom and inclined to conform `with the incline or inclines of the hull bottom, and the upper plate 1 set in a level position, the which overlap the arcuate peripheries of the re ybolts I5`I‘c`o?necting the segments II and I2 per mitting such-relative angular adjustment of the peripheries of these’segment's andv througlh"`holes in the segments I2, these bolts having-_washersull spective segments I I and serve as~meansrfonñrmly , »v clamping the segments Il .and I2 together >after they have been adjusted 'into the‘a‘ppr'opriate angular relationship. - The lower plate 8 of the stand is adapted to mounted' on'the., bottom I ofthe hullv and to be clamped in water-tight 'engagement therewith by bolts I8 or other suitable/means. A ferrule‘or pipe 28, composed oflead or other Vsuitable ductile 20 material andof a size to ñt over the discharge end of the bowl below the'flange 6 thereon is 'extend ed through the' openingsv 9 and I8 in theplates- 1 and 8 and through an- opening 2i of appropriate 25 size' formed in the bottom" I of the hull.' The’lowe'r endof this ferrule is' peened or. otherwise flanged outwardly‘ag'ainst the Vunderside of the hull bot tom I and maybe secured in water-tight engage ment therewith by> nails' 22. ' The upper' end of 'ferrule is 'peened or otherwise ,flanged out so the wardly and is secured, as by'nails 23 to thefupper side of a board 24 of wood or other suitable vma terial which is placed on'the upper side ofthe plate 1, the board 24 having a central 'opening 35 therein of suñicient size ‘_forjthe passage ofthe ` ferrule. The bowl is ñrmlysecured on the stand by bolts 25'which extend throughthe flange 6, plate'l and board 24,’these bolts, when tightened, firmly securing the bowl on the top of `the stand 40 and clamping the outturned flange on the ferrule ' and> thus lforming a'water-tight joint'between' the bowl and the ferrule. i , ~ Y ’The present invention provides means for auto matically 'withdrawing refuse _from the bowl while the boat is in/motion, such means compris-7 45 ing a shoe 26'which may be composed of a cast ing the `forward 'end of ,which is preferably curved and is provided ‘with an aperture 21 and the rear . end of which is open, as at 28 for the discharge of the refuse.- "The shoe _is provided'at'its upper 50 edge, at the frontl and sides> thereof, with anout turned ñange 29 adapted to ñt‘against the underf side of the hull bottom and to be secured'in wat'eré tight engagement therewith by screws 38'or other suitable securing means. n' The interior"- of~ the 55. shoe communicateswith the' lower‘ endv ofthe ferrule The present 20'. invention " ' 'also provides ' " Y means " ` >for receiving water from the ' exterior of' the boat while the latter is in motion and for forcing the 60 ' water upwardly into‘the flushing channel 2in platesand the lbolts. I1 locking the plates in an gularly "adjusted relationship. The bowl is pref erablym‘ounted at such as height with respect to the water-line :I3-fx of- the boat as to cause water fromv theexteriorof the `boat/to normally 'ri'se‘îin 'the lower end 'ofthe bowl'toï a height slightlyiabove'the flange 6 thereof as shown in Figlfl,v themounting of the bowl at the desired 20 height ’being "accomplished by placing the bolts f ‘I 5 _ and' `I1` in `Ithe"apprc'npriate vrvertically ' spaced holes I4 "inthe segments I2, tightening of these _bolts Nfirmly 'securing'the Vplates 1 and 8 in ad justed'relationship; In installing the'closet in 25 ak boatv‘the bottom of the'hull of which slopes 'upwardly from'the rkeel to theV side of the boat, the 'stand' maybe mounted on the hull bottom inthe'm’anner shown' in Fig. 4, the segments Il and I2v being ylocated at the front and rear sides 30 vof " the ferrule 20V andthe plates 1 and 8 being properly' adjusted'angularly about the bolts -I 5 as _pivotal‘centers so' thatv the plate 8 may occupy inclined'position'corresponding to- the lat v eral slope ofthe hull bottom and the’upper plate 35 1" may`- occupy a level position, and- the plates are f_ìrrnly‘secured in such angular relationship by"> tightening 'of' the bolts I5 and I1. In installingthe' bowl inìa boat vthe bottom of which lslopes in `‘afore and ‘aft .direction as well as laterally, 40 the'slope Of'the hull bottom in both 0f said dí rections may be compensated for by rotating the stand"`more .or‘ less about its vertical axis Vfrom the'l positionshown in Fig. 4 into the position shownj‘lfor example in Fig. 5 while the lower plate 8_vrests on kthe boat bottom, and rocking the `-ulf‘niierl p_late'1 'about the‘pivot bolts I5 un tiljitassumes aflevel position, after which the plate _1' isñrmly secured in such position by tight ening ofjthe'bolts I5 and> I1. In'installing the bowlunderîany‘of "these conditions. the ferrule 2_8"is_inserted‘after'the upper and lower plates of the 'stand haveibeen’adjusted with respect to the height of the bowl above- the hull bottom and thefslope' or slopesv of the hull bottom, rthe duc tilegrnaterial ‘of which ferrul'e is composed, as 55 for>- eXarnple‘of lead, enabling it to be shaped atjits upperîend to'co‘nforni with the level posi tion'of' the bowl and at lits lower end to con form with the slope or slopes of the' hullr bottom, - andalsoîpermittingit to be peened'or ñanged the upper portion of the bowl,"such means l*com prising hollow acasting scoop havingv 3l, which a may surrounding jbe composed lflangeof 32 as hereinbefore described.. adapted to iit'againstl the Vunderside of.' thehull above‘the bottom of ’ the hull, ther standmay be 65 j_ In‘rtli ` "installations where itis desirable or l oplacethe bowl in a higher position e» l ` t bottom and'to be secured in water-tight engage-I adjustedin the mannerV shown in Fig. '1. In this ment therewith by 'screws 33 'or other'suitable abovey the bottomV member or plate 8 than in'Fi'g'. means. The forward side of the vscoop or theside thereof which ‘faces the bow of the boat is pro; 70 vided with a suitable'lnumber ‘of slots', 34 to admit water thereto incident'to the forwardmotion of the boat, and the -rear'portion'of ther scoop, is formed at >the top `withja plate 35 into ,whi'cha pipe 38 is threaded,`lthi_s pipe being yconnected'at 7,5 its upper end Yto the .lrlushing `"channel 3 inthe figure; the- upper member orv plate 1 is set higher 5;.and"th`ebolts YI5 are placed'in holes I3 in the segments " H‘ which are adjacent to the 'lower ‘Y edges‘thereof and in the upper‘holes I4 inthe segments I2, and bolts Iiia are placed in ap propriate holes' |3`in the segmentsv 'II immedi ately" above the'upper curved edges of thefseg ments ,1.2, these bolts having peripherally toothed 75 2,130,954 or serrated washers I6b thereon which are eccen tric to the respective bolts I6a and are adapted to grip or mesh with the correspondingly toothed 0r serrated curved edges I2a on the segments I2. In using this arrangement, the upper and lower plates 'I and 8, after being adjusted to the desired height and set in the proper angular relation to bring the upper plate ‘I level and com pensate for slope of the bottom of the hull in a 10 fore and aft and/or a lateral direction, are se curely locked by rotating the eccentric washers in opposite directions on the respective bolts I6a until these washers engage the respective ser rated edges of the segments I2, the longest radii of the eccentric washers then extending diver gently toward opposite sides of the axes of the bolts |63, and then tightening the bolts II'Sa and the bolts I5, the divergent setting of the eccen tric washers causing them to lock against the segments I2 and to ñrmly prevent rocking of the upper plate 'I in either direction relatively to the lower plate 8. The stand as thus adjusted, may be otherwise installed and used in the same manner as hereinbefore described. In operation, water from the exterior of the boat will normally rise into the lower end of the bowl to the level of the water-line st_aî, or substantially so. Any refuse that may be con tained in the lower end of the bowl or in the 30 ferrule, while the boat is at anchor or not in motion, will be withdrawn and washed out of the discharge end 28 of the shoe 2E by water 25 entering the shoe through the aperture 21 in cident to the tide or current of water beneath 35 the hull. When the boat is in motion in a forward direction, water will enter the slots 34 in the scoop 3| and will be forced by the pressure of the water, incident to the forward motion of the boat, upwardly through the pipe 35 into 40 the channel 3 surrounding the upper end of the bowl and such water will discharge through the openings 4 into the bowl, thereby flushing or washing it. At the same time, the movement of the shoe 26 through the water will produce a 45 partial vacuum at its rear discharge opening 28 which will act to withdraw water and refuse from the lower end of the bowl and ferrule 29' and to eject the same into the water, and also water will enter the aperture 21 in the forward 50 wall of the shoe thereby producing a current rearwardly in the shoe which will assist in eject ing refuse therefrom. Since the shoe 26 covers the lower or discharge end of the ferrule 20, it will serve to prevent splashing of water upwardly 55 into the bowl incident to pitching of the boat in the water. The stand provided by the present invention enables the closet bowl to be readily mounted at the desired height with respect to the water 60 line of the boat so that the proper amount of water may be normally contained in the lower portion of the bowl to provide a seal, and it en ables the bowl to be mounted in a level position irrespective of the fore and aft or transverse slope of the bottom of the» boat hull, thus obvi ating the necessity of cutting a special block for mounting the bowl to suit each installation as heretofore required and which is difficult and laborious. The shoe beneath the bowl discharge will ef fectually withdraw refuse from the lower portion 3 of the bowl and from the ferrule automatically in consequence of the forward motion of the boat in the water, and at the same time, the scoop will force water from beneath the boat upwardly into the upper portion of the bowl for washing or flushing it. While the boat is anchored or at rest, refuse will be washed automatically from the shoe by the tide or current of the water which will enter the aperture in the front end of the shoe and pass out through the discharge opening 10 in the rear thereof, thereby keeping the shoe clear of refuse. These results are all attained by the present invention without requiring the use of valves, pumps or other accessories which are liable to get out of order and are otherwise ob 15 jectionable. I claim as my invention: 1.
