_Q.'Zl'he _present invention relates to water closets,
anjdfmore‘especiallyito those adapted for use on
boats; andthe primaryy object is to provide a
5 ïlwatencloset which may be mounted with the lower
end’of `the bowl or yhopper at or immediately
‘bel‘owthe water-'line of ‘the boat but which shall
‘effectively ejeCtQits contents >automatically and
-avoid _splashing of water upwardly into the bowl
'without'~ requiring the use of valves, pumps or
other-*objectionable
parts.

@Amore particular object of the invention is to
providemeans below the ’bottom of the hull of
_theboat‘ _to receive refuse from the bowl and
I _ operative, 'bythe action of the water due to the
15
forward motion of the boat, to effectively With
draw and vdischarge such refuse, said means also
_serving to prevent splashing ofwater upwardly
into the-bowl due to pitching or rolling of the
__ boat, either while in motion or anchored, said
meansbeing self-cleaning while the boat is an
chored orv not in motion.
~
"î'iAnother object is to provide means, operative
_automatically ‘in’ consequence of the forward mo
fon'of the boat (in the water, toforce water up
wardlyjand- discharge it into the upper portion of
the bowl yfor flushing it.`
` `
f’Affurthe'r object of the invention is to provide
a ~`vnovel ‘and improved -mounting forthe bowl
which V'is adjustable to enable the bowl to be
so mounted at different heights above the bottom of
the' hull of the boat so that the lowerend or dis
lcharge. outlet 4of the bowl may occupy a pre
determined orV desired height with respect to the
waterfline and to compensate for diiîerent angles
of transverse and longitudinal inclinations of the
bottom of the hull 'of the boat in order that the
bowl‘may occupy an «upright or level position when
installed in diñerent boats.

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

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.
