page_text: Improvements in Pump Water Closets.
I, GEORGE BETHELL HOWELL, a citizen of the United States, and resident of
No. 523 Cherry Street, in the City of Philadelphia, in the County of Philadelphia
and State of Pennsylvania, U.S.A.. Manufacturer, do hereby declare the nature of
this invention to be as follows-
This invention relates to water-closets, but more particularly to pump water-closets
for marine purposes.
When the water-closets on vessels are located below or slightly above the water line,
it is necessary to provide a pump into which the contents of the bowl are first drawn
and then forced overboard; a small water-pump being operated to supply clean water
to the bowl during the discharging process. After the pumping has ceased it becomes
necessary to fill the bowl with clean water, and for this purpose it has been the practice,
as far as I am aware, to provide a separate valve, which is either operated by a
hand-pull or by means of a foot-treadle, both of which are decidedly objectionable
for the reason that very often (owing to the more or less complicated construction of
marine closets generally) they are left in a foul condition or without the necessary
water remaining in the bowl, owing to the fact that the user either does not know
how, or does not care to take the necessary trouble to operate the necessary parts to
place the closet in the proper condition. Another objection to closets so supplied with
water is that the refill is obtained by operating the valve until the proper amount of
water is supplied to the bowl. This cannot be properly ascertained while sitting upon
the seat, as there is no means of measuring the quantity of water entering the bowl
except by the eye, and should it be attempted to do this without watching the
progress of refilling, there is great danger of an overflow, or an insufficient quantity
of water being supplied to the bowl by reason of the valve not being operated for
the proper length of time.
The primary object of my invention is to overcome these and other objectionable
features, by providing means, operated from a single source, for effecting the proper
discharge of the contents of the bowl, injecting clean water into the bowl while the
discharge or soil-pump is in operation, and finally supplying a measured quantity of
water to the bowl to be retained therein until the contents of the bowl are again
discharged.
Other objects are to provide simple and efficient means for governing the supply of
water to the bowl so as to preclude all possibility of an overflow; and to provide a
simple and efficient device which may be employed in connection with various forms
of closets and pumps.
The invention will be hereinafter more particularly described with reference to the
accompanying drawings, which form a part of this specification, and then pointed
out in the claims at the end of the description.
In the drawings, wherein similar letters of reference denote similar parts, Figure 1
is a rear view, partly in section and partly in elevation, of an apparatus embodying
my invention

page_text: Figure 2 is a vertical sectional view through the closet, taken on the line II-II
of Figure 1.
Figure 3 is a detail sectional plan view through the water-pump and water-ways,
taken on the line III-III of Figure 1.
Figure 4 is a side view of another form of apparatus embodying my invention; and
Figure 5 is a fragmentary rear view, partly in section and partly in elevation, of
the form of apparatus shown in Figure 4.
In said drawings, A may designate a closet of the pedestal type having the bowl a
thereof provided with the usual seat and cover, and supported upon a suitable
base-plate A¹. The lower portion of the closet-bowl is open and suitably connected
to a soil pipe a¹, which latter may be angular in form and connected to the lower
portion of a discharge or soil-pump B. This pump, as well as the closet, may be of
any desired form, and may have a vertically reciprocating piston or plunger (shown
in dotted lines in Figure 4), so that when the piston is operated, the contents of the
bowl will be drawn therein and forced through the discharge soil-pipe b overboard
clear of the sides of the vessel, suitable valves, shown in dotted lines, being provided
in the lower portion of the pump cylinder, the piston and the discharge soil-pipe,
respectively, to secure proper action of the pump.
For the purpose of supplying clean water to the closet bowl, and for automatically
controlling such supply, I may provide a water-pump C, and a casing or cylinder D,
containing an automatic valve D¹. This cylinder and the pump may be variously
arranged with respect to each other, and in Figure 1 said cylinder is located above
and to one side of the pump. A pipe d leads overboard or to some other source of
water-supply and is connected to the inlet of the casing or cylinder D above the
valve D₁, said valve preferably comprising a rod, a disk or other valve d² arranged
upon said rod and adapted to shut off the flow of water through the inlet pipe d
when resting upon the seat 3, and a piston d adapted to move vertically in said
cylinder. The pump may be supported upon a hollow base d', and may communicate
therewith through an aperture or opening arranged below the lower open end of the
pump, a clack or other valve do, being provided to prevent the water entering
the pump through said opening from being forced back into the base. This base
may be connected to the cylinder D by a water-way or pipe, as at d, which latter
extends from said cylinder below the seat d³, and may have a portion thereof formed
integrally with the pump, and the other portion formed integrally with the cylinder,
or said pipe may be formed in one piece or separately from the pump and said
cylinder. At d" and d (Figures 1 and 3) are pipes or water-ways which may be
formed integrally with and extend substantially parallel to said pump. One of said
pipes or water-ways, as d', communicates with the base d5 at one end, and at the
other end communicates with the upper end of the pump and with the lower end of
the cylinder D, while the pipe or water-way d" has its lower end communicating with the
lower end of the pump and its upper end with the lower end of said cylinder. The
upper ends of the pipes or water-ways do and do, where they communicate with
the cylinder D, are each controlled by suitable clack or other valves do, arranged
directly over said pipes (one only of said valves being shown), and pipe d', where it
communicates with the base d', is controlled by a suitable valve ", while the lower
end of the pipe or water-way do, where it enters the pump, is also provided with a
suitable valve, as at d¹², said water-ways or pipes being of any suitable construction
and arranged in any preferred manner.
The portion of the cylinder D, in which the pistou of the valve D1 is adapted to
slide, may be located somewhat above the valves (10, and may be divided into two
sections by an annular or other opening d¹³ which serves to connect the lower section
with a chamber d'. This chamber may be annular and arranged around said lower
section, and may have one or more preferably small apertures d¹ connecting said
chamber with the space above the valves 10 and below the lower section, so that
after the piston-valve D¹ is raised by the water forced into the cylinder D by the
pump C, the water above said valves do will resist the backward or downward move-
ment of said piston-valve and will gradually pass into the annular chamber d¹

page_text: through said aperture or apertures d¹ until the disk or valve d² reaches its seat d³.
The upward movement of the valve D¹ may be limited in various ways, or, as shown,
by the rod thereof striking the cap de arranged on the cylinder D, and instead of
depending upon the weight of the valve and pressure of the water on its upper surface
for its downward movement, a suitable spring or other means may be employed to
assist its return. A pipe e has one end thereof opening into the chamber d¹, and its
other end suitably connected to a pipe or water-way e¹, which latter may form a part
of the bowl and lead to or near the top thereof. The pipe or water-way el may
have one or more lateral apertures e² leading to an apertured rim or other flushing
device of the bowl, and with one or more apertures leading to a refill chamber e*
the latter being filled with one or more apertures e' preferably located at or near the
water line of the bowl, so as to gradually supply the proper amount of water to the
bowl after the discharging process. By this means, when the pump C is operated so
as to force water into the cylinder D, the valve D₁ will be lifted and automatically
suspended so as to prevent shutting off the water while the pump is in action, by
reason of the pressure and retarding action of the water under the piston of said
valve, thus permitting the proper quantity of water to be constantly supplied to the
bowl; but as soon as the pump ceases to operate, the valve will gradually
automatically lower and shut off the water from the inlet pipe so as to prevent an
overflow.
In order to simultaneously operate the discharge-pump B and the water-pump C,
may connect the upper end of the piston-rod of the pump C to an arm ƒ (Figures 1
and 4) extending outwardly from a suitable yoke, which latter may have pendent
arms extending on opposite sides of the pump cylinder and connected to levers f
intermediate their ends. These levers may have one of their ends pivoted to a
bracket pendent from the discharge soil-pipe b or other portion of the pump, and
their outer ends connected by links 73 to crank-arms f, said crank-arms being
arranged on a suitable shaft f5 supported in brackets or standards extending upwardly
from the base-plate A¹. An operating lever fo is secured to the rocking shaft f³ so
that as said lever is moved back and forth the levers f² will be rocked on their pivots,
and a vertical reciprocating motion imparted to the yoke f¹, and the plungers of both
of the pumps. Though the means shown for operating the pistons of the pumps is
very effective, it is obvious that other means may be employed when desired.
The operation of the invention will be readily understood from the foregoing
description, when taken in connection with the accompanying drawings.
Assuming that there is sufficient water in the water-ways, the base d³, and the
water-pump, from a previous operation, and the plungers of the discharge and said
water-pump are actuated by the mechanism heretofore described, it will be seen that
as the plunger in the water-pump is forced downward, for instance, water previously
in said pump will be forced past the valve 12 into the water-way do, and then past.
the valve 10, controlling its upper end, and into the cylinder D. The pressure of
the water against the piston d' of the valve D¹ will raise the disk d² off its seat and
force the piston into the upper section of the portion of the cylinder in which said
piston slides, so as to permit the water to pass through the annular opening d¹³, into
the chamber d14. From here the water enters the pipe e and then passes up the
water-way el through the lateral openings into the flushing rim and the refill
chamber e of the closet bowl. During the down-stroke of the plunger in the water-
pump, water will flow or be drawn past the disk or other valve d² into the base d³,
and then past the valve d up the water-way d³ and into the upper end of the pump
as indicated by the arrows." The return or up-stroke will open the valve de, drawing
water into the pump cylinder, and will close valve d¹ forcing the water above the
piston in said pump past the valve 10 into the cylinder D, again raising the piston
valve D¹, if it has lowered, and is then forced into the chamber d, and from there
into pipe e, in a similar manner to the previous stroke of the pump plunger. The
water below the piston d' of the valve D¹ will gradually pass through the aperture
1 so as to permit the valve d² to gradually automatically rest upon the seat d³, thus
shutting off the supply of water from the inlet pipe to prevent an overflow, and at

page_text: the same time preventing the shutting off of the water while the pump is in opera-
tion. As the discharge-pump B is connected so as to operate with the water-pump
C, the contents of the bowl will be drawn therein and forced through the soil or
discharge pipe b overboard free of the vessel simultaneously with the forcing of clean
water into the bowl by the water-pump. After the pumps cease to be operated the
water in the refill chamber will flow through the aperture or apertures e5 in the
bowl, thus supplying a measured quantity of water to be left standing in said bowl.
I thus provide a simple and efficient marine or pump water-closet, by which the bowl
may be simultaneously discharged and clean water forced therein during the dis-
charging process, and a proper quantity of clean water supplied to the bowl to be
left standing therein after the discharge.
In Figures 4 and 5 I have shown a device embodying my invention in which the
water-pump is single-acting instead of double-acting as in Figure 1.
In this case
the discharge-pump, and the means for simultaneously operating the water and the
discharge pumps are the same as in the form already described. The cylinder F,
though slightly different in construction, and the piston-valve and the action of
said valve are substantially the same as the cylinder D and the piston-valve D¹, aud
will therefore not be referred to in detail. The pump G and the cylinder F may
have open screw-threaded lower ends adapted to fit into screw-threaded apertures
or recesses in the base g so as to be rigidly held thereon. This base has a lower
water-way g¹, communicating with the cylinder F, below the valve-seat g² therein,
by a water-way or pipe g3, and has a water-way g arranged above the water-way g³
and beneath the pump G, an opening controlled by a suitable valve g³ being
provided so as to form a communication between the lower water-way and said pump.
The upper surface of the base may have an opening controlled by a suitable valve 76
so as to form a communication between the cylinder F, below the piston-valve D¹, and
the water-way g*. The valve D¹ instead of being guided simply by the piston d
thereof may have its rod passed through a boss of a spider or yoke, as at g7, arranged
at the upper portion of the cylinder F, or secured, as shown, to the lower end of the
inlet pipe d.
The operation is substantially the same as that of Figure 1, except that the pump
forces water into the cylinder F and the bowl during the down-stroke only, by which
movement the valve g³ is closed, the valve g opened, and the piston-valve D₁ lifted as
shown. The water then passes into the annular chamber d¹ and into the pipe g³, which
connects said chamber to the bowl in the manner heretofore explained. During the
up-stroke of the piston, the valve go is closed and water enters the water-way g³ and
is drawn past the valve go into the pump to be forced into the chamber F during
the down-stroke, the resistance of the water below the piston-valve D¹ preventing
said valve from shutting off the water during the up-stroke of the pump plunger.
It. is obvious that various changes may be made in the construction and arrange-
ment of the parts; that other means may be provided for permitting the gradual
return of the automatic valve, or arranging a valve so as to act automatically; that
more than one valve may be employed; and that some of the parts may be dispensed
with or others substituted therefore, without departing from the spirit of my
invention.

page_text: I, GEORGE BETHELL HOWELL, a citizen of the United States, and resident of 523
Cherry Street in. the City of Philadelphia, in the County of Philadelphia, and State
of Pennsylvania, U.S.A., Manufacturer, do hereby declare the nature of this

The invention will be hereinafter more particularly described with reference to
the drawings filed with my provisional specification and pointed out in the claims
at the end of the following description..

embodying my invention.

the form of apparatus shown in Figure 4.

page_text: In said drawings, A may designate a closet of the pedestal type having the bowl a
thereof provided with the usual seat and cover, and supported upon a suitable base-
plate A¹. The lower portion of the closet-bowl is open and suitably connected to a
soil pipe a¹, which latter may be angular in form and connected to the lower portion
of a discharge or soil-pump B. This pump, as well as the closet, may be of any
desired form, and may have a vertically reciprocating piston or plunger (shown in
dotted lines in Figure 4), so that when the piston is operated, the contents of the

respectively, to secure proper action of the pump.
For the purpose of supplying clean water to the closet bowl, and for automatically
controlling such supply, I may provide a water-pump C, and a casing or cylinder D,
containing an automatic valve D₁. This cylinder and the pump may be variously
arranged with respect to each other, and in Figure 1 said cylinder is located above
and to one side of the pump. A pipe d leads overboard or to some other source of
water-supply and is connected to the inlet of the casing or cylinder D above the
valve D¹, said valve preferably comprising a rod, a disk or other valve d arranged
upon said rod and adapted to shut off the flow of water through the inlet pipe d
when resting upon the seat d³, and a piston d adapted to move vertically in said
cylinder. The pump may be supported upon a hollow base d³, and may communicate
therewith through an aperture or opening arranged below the lower open end of the
pump, a clack or other valve de being provided to prevent the water entering the
pump through said opening from being forced back into the base. This base may be
connected to the cylinder D by a water-way or pipe, as at d7, which latter extends
from said cylinder below the seat d³, and may have a portion thereof formed
integrally with the pump, and the other portion formed integrally with the cylinder,
or said pipe may be formed in one piece or separately from the pump and said
cylinder. At d³ and do (Figures 1 and 3) are pipes or water-ways which may be
formed integrally with and extend substantially parallel to said pump. One of said
pipes or water-ways, as d³, communicates with the base d at one end, and at the
other end communicates with the upper end of the pump and with the lower end of
the cylinder D, while the pipe or water-way has its lower end communicating
with the lower end of pump and its upper end with the lower end of said cylinder.
The upper ends of the pipes or water-ways d8 and do, where they communicate with
the cylinder D, are each controlled by suitable clack or other valve d¹º, arranged
directly over said pipes (one only of said valves being shown), and pipe d³, where
it communicates with the base d³, is controlled by a suitable valve d¹¹, while the
lower end of the pipe or water-way dº, where it enters the pump, is also provided
with a suitable valve, as at 12, said water-ways or pipes being of any suitable
construction and arranged in any preferred manner.
The portion of the cylinder D, in which the piston of the valve D1 is adapted to
slide, may be located somewhat above the valves do, and may be divided into two
sections by an annular or other opening d¹s which serves to connect the lower section
with a chamber d. This chamber may be annular and arranged around said lower
section, and may have one or more preferably small apertures d¹ connecting said
chamber with the space above the valves do, and below the lower section, so that
after the piston-valve D¹ is raised by the water forced into the cylinder D by the
pump C, the water above said valves d 10 will resist the backward or downward move-
ment of said piston-valve and will gradually pass into the annular chamber d14 through
said aperture or apertures 15 until the disk or valve d² reaches its seat d. The
upward movement of the valve D' may be limited in various ways, or, as shown, by
the rod thereof striking the cap d¹e arranged on the cylinder D, and instead of
depending upon the weight of the valve and pressure of the water on its upper
surface for its downward movement, a suitable spring or other means may be
employed to assist its return. A pipe e has one end thereof opening into the chamber d",
and its other end suitably connected to a pipe or water-way e', which latter may form

page_text: a part of the bowl and lead to or near the top thereof. The pipe or water-way el
may have one or more lateral apertures e³ leading to an apertured rim or other
flushing device of the bowl, and with one or more apertures.e leading to a refill
chamber e', the latter being provided with one or more apertures e preferably located
at or near the water line of the bowl, so as to gradually supply the proper amount of
water to the bowl after the discharging process. By this means, when the pump C
is operated so as to force water into the cylinder D, the valve D' will be lifted and
automatically suspended so as to prevent shutting off the water while the pump is in
action, by reason of the pressure and retarding action of the water under the piston
of said valve, thus permitting the proper quantity of water to be constantly supplied
to the bowl; but as soon as the pump ceases to operate, the valve will gradually
automatically lower and shut off the water from the inlet pipe so as to prevent an
overflow.
In order to simultaneously operate the discharge-pump B and the water-pump C, I
may connect the upper end of the piston rod of the pump C to an arm ƒ (Figures 1
and 4) extending outwardly from a suitable yoke, which latter may have pendant
arms extending on opposite sides of the pump cylinder and connected to levers f
intermediate their ends. These levers may have one of their ends pivoted to a
bracket pendent from the discharge soil-pipe b or other portion of the pump, and
their outer ends connected by links to crank-arins f, said crank-arms being
arranged on a suitable shaft supported in brackets or standards extending outwardly
from the base-plate A¹. An operating lever is secured to the rocking shaft f5 so
that as said lever is moved back and forth the levers will be rocked on their pivots,
and a vertical reciprocating motion imparted to the yoke f¹, and the plungers of both of
the pumps. Though the means shown for operating the pistons of the pumps is very
effective, it is obvious that other means may be employed when desired.
The operation of the invention will be readily understood from the foregoing
description, when taken in connection with the accompanying drawings.
Assuming that there is sufficient water in the water-ways, the base d', and the
water-pump, from a previous operation, and the plungers of the discharge and said
water-pump are actuated by the mechanism heretofore described, it will be seen that
as the plunger in the water-pump is forced downward, for instance, water previously
in said pump will be forced past the valve d¹ into the water-way and then past the
valve do, controlling its upper end, and into the cylinder D. The pressure of the
water against the piston of the valve D¹ will raise the disk 2 off its seat and force
the piston into the upper section of the portion of the cylinder in which said piston
slides, so as to permit the water to pass through the annular opening d¹³, into the
chamber 4. From here the water enters the pipe e and then passes up the water-
way e through the lateral openings into the flushing rim and the refill chamber e' of
the closet bowl. During the down-stroke of the plunger in the water-pump, water
will flow or be drawn past the disk or other valve d² into the base d³, and then past
the valve up the water-way d8 and into the upper end of the pump as indicated by
the arrows.
The return or up-stroke will open the valve po, drawing water into the
pump cylinder, and will close valve d" forcing the water above the piston in said
pump past the valve d¹ into the cylinder D, again raising the piston valve D', if it. has
lowered, and is then forced into the chamber d, and from there into pipe e, in a
similar manner to the previous stroke of the pump plunger. The water below the
piston d of the valve D' will gradually pass through the aperture d¹5 so as to permit
the valve to gradually automatically rest upon the seat d³, thus shutting off the
supply of water from the inlet pipe to prevent an overflow, and at the same time
preventing the shutting off of the water while the pump is in operation. As the
discharge-pump B is connected so as to operate with the water-pump C, the contents
of the bowl will be drawn therein and forced through the soil or discharge pi pe b
overboard free of the vessel simultaneously with the forcing of clean water into the
bowl by the water-pump. After the pumps cease to be operated the water in the refill
chamber will flow through the aperture or apertures e in the bowl, thus supplying
a measured quantity of water to be left standing in said bowl.

page_text: I thus provide a simple and efficient marine or pump water-closet, by which the
bowl may be simultaneously discharged and clean water forced therein during the
discharging process, and a proper quantity of clean water supplied to the bowl to be
left standing therein after the discharge.
In Figures 4 and 5 I have shown a device embodying my invention in which the
water-pump is single-acting instead of double-acting as in Figure 1. In this case
the discharge-pump, and the means for simultaneously operating the water and the
discharge pumps are the same as in the form already described. The cylinder F,
though slightly different in construction, and the piston-valve and the action of
said valve are substantially the same as the cylinder D, and the piston-valve D¹, and
will therefore not be referred to in detail. The pump G and the cylinder F may
have open screw-threaded lower ends adapted to fit into screw-threaded apertures or
recesses in the base g so as to be rigidly held thereon. This base has a lower
water-way g¹, communicating with the cylinder F, below the valve-seat g² therein,
by a water-way or pipe 93, and has a water-way g' arranged above the water-way g³
and beneath the pump G, an opening controlled by a suitable valve gs being provided
so as to form a communication between the lower water-way and said pump.
The
upper surface of the base may have an opening controlled by a suitable valve g" so as
to form a communication between the cylinder F, below the piston-valve D¹, and the
water-way g. The valve D' instead of being guided simply by the piston d¹ thereof
may have its rod passed through a boss of a spider or yoke, as at g7, arranged at the
upper portion of the cylinder F, or secured, as shown, to the lower end of the inlet
pipe d.
The operation is substantially the same as that of Figure 1, except that the pump
forces water into the cylinder F and the bowl during the down-stroke only, by which
movement the valve g5 is closed, the vlave gº opened, and the piston-valve D¹ left as
shown. The water then passes into the annular chamber d¹ and into the pipe gs,
which connects said chamber to the bowl in the manner heretofore explained. During
the up-stroke of the piston, the valve g is closed and water enters the water-way g³
and is drawn past the valve g5 into the pump to be forced into the cylinder F during
the lown-stroke, the resistance of the water below the piston-valve D¹ preventing
said valve from shutting off the water during the up-stroke of the pump-plunger.
It is obvious that various changes may be made in the construction and
arrangement of the parts; that other means inay be provided for permitting the
gradual return of the automatic valve, or arranging a valve so as to act automatically;
that more than one valve may be employed; and that some of the parts may be
dispensed with or others substituted therefor, without departing from the spirit of
my invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
1. In a pump water-closet, the combination with a bowl provided with a refill
chamber communicating therewith and with means adapted to permit water to enter
to flush the bowl, of a discharge-pump for the bowl, a second or water-pump and
connections therewith for supplying clean water to the refill chamber and to the bowl
for flushing purposes, means for simultaneously operating both pumps, together with
an automatically actuated valve controlling the supply of water to said second pump
and normally suspended in an open position to permit water to be supplied to the
bowl and the refill chamber while the pumps are in operation, and which
automatically shuts off the supply of water when the pumps are at rest, whereby, by
a single operation, the proper quantity of clean water may be supplied to the bowl
during and after the discharging process, and the water automatically shut off to
prevent an overflow, substantially as described.
2. In a water-closet, the combination with a pump, of an automatically actuated
valve controlling the water supply thereto and normally suspended in an open

page_text: position by said pump while in operation, and which automatically shuts off the
supply of water when the pump is at rest, substantially as described.
3. In a water-closet, the combination with a bowl, of a discharge-pump therefor,
a second or water-pump and means connecting said pump to the bowl for supplying
clean water thereto, means for simultaneously operating both pumps, together with
an automatically actuated valve controlling the supply of water to said second pump
and normally suspended in an open position while said latter pump is in operation to
permit clean water to be supplied to the bowl and which automatically shuts off the
supply of water when the pumps are at rest, substantially as described.
4. In a pump water closet, the combination with a bowl, of a pump, a discharge
conduit or water-way leading from the pump to the bowl, a valve controlling the
inlet to the pump, and means for operating said valve located in the discharge
conduit and operated by the flow of liquid therethrough, substantially as
described.
5. In a pump water closet, the combination with a bowl, of a pump, a discharge
conduit leading from the pump to the bowl, a supply passage in communication with
the pump, a valve located in said passage and means for operating said valve located

conduit, substantially as described.
6. In a pump water closet the combination with a bowl, of a pump, a discharge
conduit or water-way leading from the pump to the bowl, a supply passage leading to
the pump, and a valve located in said supply passage adapted to be opened by the
