WILLIAM ROBERT LAKE of the firm of Haseltine, Lake and Co, Patent Agents,
Southampton Buildings London "IMPROVEMENTS IN AND RELATING TO WATER-
CLOSETS AND SEWERS AND TRAPS FOR THE SAME [A communication to him
from abroad by Charles F. Pike of Philadelphia Pennsylvania, Engineer, and

"
This invention has relation to water closets, and sowers, and soil pipe and other
traps and has for one of its objects to provide for sealing these fixtures by means
of a continuously running stream of water, which is then maintained in a
fresh condition for absorbing sewer gas and preventing the generation of fungus
growth
The said invention has for a further object to provide a disinfectant running
fluid seal for such fixtures whereby they are rendered odourless,
The said invention still further rolates to means for cleansing and disinfecting
the traps of water closets, sewers and the like
"
According to the said invention I provide various combinations of devices for
effecting a running water seal and a disinfectant seal for the water closet, the
traps and the sewers; the water closet having a pan, clapper or plug valve, or
being without a valve, has a water supply pipe provided with a perforated cock
or a branch connection leading to said closet whereby a stream or flow of water
continuously passes from the water supply pipe to the closet, thence to its trap
Pavice 1.1

page_text: and soil pipe; said branch pipe may be arranged in any suitable or desired
manner, and if desired may be provided with a pet cock for regulating the flow of
water therethrough
Where the running water seal is used in connection with pan or valve closets
the lover operating the pan or valve is also sealed around the opening through
which it passes in the receiver or container and the joint of the latter is so
arranged that a water seal is provided therefor. Such seal is made by forming a
connection with the water supply pipe for the closet. Such construction provides
a closet in which all the parts thereof are sealed with a fluid seal so that there are
no openings through which sewer gas or odours can escape. The lever operating
the pan is sealed as follows, vis, from the lid of the receiver depends a flange
entering a pocket in the receiver. Through said flange passes said lever and
connects with a crank secured to the pan shaft. A continuous stream of water
passes into said pocket and rises above the lower edge of said flange before it
escapes from the pocket so that said edge is always immersed in water and senled
thereby, consequently the said operating lever can be moved up and down within
the Bange without breaking the scal
Instead of using the running water for the seal a given supply of mercury may
be employed; where a disinfectant is designed to be used it is placed in a reservoir
and water supplied thereto which is conducted to the closet, trap, retainer and
sealing chamber for the valve or pan operating mechanism as above described for
the running disinfectant fluid seaÎ.
Such seals may be applied to sewer inlet traps and to the sewers by leading a
pipe thereto which has connection with a water main or other source of constant
water supply
By inserting a disinfectant holding tank in the path of said pipe a disinfectant
running seal is provided
Such fixtures are cleansed in substantially the following manner, a flexible tube
is inserted into the same and is perforated at its lower end.
It is then attached to a pump which is operated to force a stream of water into
said pipe, which emerging through the perforations strikes the sides of the
trap or other fixture with great force; the impact of the blow soon loosens and
cleanses all fecal or other matter adhering to the sides of the trap or other fixture;
when the latter is cleansed the tube is removed and the operation of cleansing is
thereby effected without disarranging any of the parts of the closet, trap, or other
fixturo.
If desired, instead of using the impact of water a rotary or reciprocating brush
may be employed such brush being inserted into the closet or trap and operated by
hand, an air cylinder, or other mechanism.
I do not confine myself to any particular form or combination of parts for the
closets, stench-traps or sewer-inlets, nor to the means employed for cleansing the
traps as above described as the said invention embraces any kind of a water
closet, or the like having a running water scal in combination with means for
regulating the volume of the flow and any and all kinds of mechanisin for
cleansing the same by the impact of jets of fluid or by reciprocating or rotury
brushes

WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, London "IMPROVEMENTS IN AND RELATING TO WATER-
CLOSETS AND SEWERS, AND TRAPS FOR THE SAME A communication to me
from abroad by Charles F Pike of. Philadelphia, Pennsylvania, Engineer, and
Edward Z Collings of Camden, New Jersey, both in the United States of
America
This Invention relates to water-closets and sewers, and to soil pipe and other
traps, and has for its objects to prevent the escape of sower or other deleterious
gases or odours from water-closets, wash-basins, sewers and other like fixtures, by
hermetically sealing them at all points by means of a continuously changing or
running scal of water or other fluid; and to cleanse and disinfect such fixtures and
their traps of all adhering fecal matter and vegetable organism.
The said invention consists essentially in the novel construction and arrangement
of parts whereby the said fixtures are sealed and to the novel method of aud
apparatus for cleansing and disinfecting them.
The present improvements are applicable to various styles of water-closets, .
traps, and sewers some of which we will now proceed to describe, preimising
that the leading object in all, except those hereinafter mentioned is to hermetically
scal all parts of the fixture including its bowl, trap and operating mechanism by
means of a running stream of water or disinfectant fluid.
In Figures 1 to 3 of the accompanying drawings I have shewn the improvements
applied to a clapper or valved closet; Figure 1 being a vertical section of the
closet and retainer partly in elevation shewing the seal for the bowl and operating
mechanism, and Figures 2 and 3 detail sections.
A indicates the closet bowl, having a flange which rests upon a corresponding
flange of a receptaclo A' formed on the container-lid A. The said receptaclo
corresponds in outline to that of the bowl, and is of such dimensions that, when
the bowl is inserted therein, a space is provided between the said parts. The
lower end of the said receptacle is formed with a groove, into which is inserted a
hollow india-rubber or other ring or packing a. A³ indicates the clapper or valve
of any suitable form having a corresponding ring or packing a' at its periphery as
shewn, and is journalled to the container in any suitable manner. It is also
provided with a slotted arın or crank which receives a pin or link a³. The latter
is pivotted to the lever a journal led to the lid As, and is provided with an arm
for operating the push rod of the cock a. The link a³ passes through a tube
depending from the lid A' which is provided with another like tube through
which passes the overflow-pipe aº from the receptacle A¹. The said tubes, pipe
and link are located in a chamber a² of the container A* having a wall which does
not extend up to the lid of the container as shewn in Figure 3.
a indicates the water supply pipe for the cock a³; a³ a branch thereof leading
to the receptacle A' and As the flushing pipe for the bowl. Water from the pipe a
continuously passes through the tube a³ into the space between the receptacle A¹
and the bowl A, such water rises in the said space and in the bowl as shown in
Figure 2 until it reaches the overflow pipe aº, through which it passes to the
chamber a, rising therein until it overflows the top edge of the wall of the said
chamber, whence it flows through the container A* to the trap and soil pipe,
forming a running water seal for the said parts. The bowl is thereby sealed, as

page_text: are also the tubes depending from the container lid, so that any sewer-gas or fecal
matter odours escaping into or arising in the container A' cannot pass out thereof,
but are held therein until absorbed by the constant flow of fresh water passing
into the said container from the chamber a7. The packing rings a a¹ being
preferably hollow are exceedingly flexible, hence any irregularities in their con-
struction are automatically taken up by the said tubes when they are brought
into contact with each other thereby forming a tight joint to prevent leakage of
water or escape of sewer gas. As the lever a is lifted after the closet is used, the
link a slides up the enclosing tube therefor and operates the slotted arm or
crank a to lower the clapper A³, whereupon the water in the space between the
receptacle and bowl together with the deposits of fecal matter, falls into the con-
tainer A'. The arm of the said lever a meanwhile striking the push-rod of the
cock a to open the same and flush the bowl. The clapper being returned to its
normal position, the water rises in the bowl as above described to form a seal
therefor.
In Figures. 4 to 6 inclusive, I have shown the running water for the seal being
injected into the closet or trap in the form of a spray ; Figure 4 being an elevation
partly sectional of a closet and trap; Figure 5 a broken section of a water closet
bowl with upper edge sealing groove and cap having a spray and Figure 6 an
elevation partly sectional illustrating the spray applied to traps of soil pipes or
other fixtures. By spraying such water, its area or extent of surface is increased
without enlarging the volume of the supply, consequently, more gas is absorbed by
a given quantity of water when in a sprayed or atomized condition, than is the
case if such water is permitted to flow in a solid or unbroken stream. The
branch a may lead from the supply pipe as to the container A* as shewn, or to
the bowl as indicated in Figure 5 or to the traps, as represented in Figure 6. If
desired a disinfectant containing reservoir may be located in the path of the pipe a®
so as to provide a spray of disinfecting fluid for the closet or trap.
In Figures 7 to 14 inclusive, I have represented improved traps for wash basins,
soil pipes and the like having means for effecting a running water or disinfectant
fluid seal therefor; Figure 7, being a longitudinal vertical section of a trap for
wash-basins or the like. Figures 8 and 9 similar views of modifications of the
same, Figure 10, a broken elevation of a detail modification and Figures 11, 12, 13
and 14 shew this invention applied to soil pipes and traps.
The trap B may consist of an elongated body b with depression b' having an
induction pipe 62, an eduction pipe 6s and a partition b. From the water supply
pipo a leads a branch a to the trap B and the said branch may, if desired, be
provided with a cock b³ for regulating the volume of the continuous flow of water
passing through the pipe a³ to the trap B for forming the running seal therefor.
Or the said tube a may have its bore so proportioned that only the required or
desired volume of water will flow, therethrough.
Again, if desired, a chamber B¹ may be formed in the trap as shewn in Figure 7,
for holding a disinfectant. The said chamber is so located that the water from the
pipe a³ will pass thereinto and be converted into a disinfecting liquid before falling
or passing into the body of the trap.
In Figure 8, the trap B is circular in outline having a cap shaped partition b*
and a disinfectant reservoir located exterior to the said trap. Figure 9, shows a
circular trap having an inverted cap-shaped partition in which the seal is formed,
and which may also contain the disinfectant. Figure 10, shows the reservoir or
chamber B¹ situated in the path of the pipes aº. The latter may lead directly to
the soil pipe as shown in Figure 11, or to the traps therefor, as illustrated in
Figures 12 and 13, while Figure 14 shews a water closet hopper and trap in one
piece having the pipe a connected therewith.
In Figure 15 which is an elevation of a water closet, with container, partly
sectional, I have shewn the pipe a leading to the container so as to form a running
water seal for the latter only.
In Figures 16 to 19 inclusive, I have shewn a modification of the water closet

page_text: illustrated in Figure 1. The bowl A is connected directly to the container lid A³;
the receptacle A¹ being dispensed with and the overflow pipe a lending from the
bowl A. Within the reservoir or chamber a7 of the container is placed a disin-
fectant chamber B¹ in all other respects the said closet is substantially similar to
Figure 17 a
that shewn in Figure 1. Figure 16 shews a plan of the retainer.
section on the line 1-1 Figure 16. Figure 18 a broken detail section on the line
2-2 Figure 16, and Figure 19 a side elevation of Figure 17 partly sectional on
the line 2-2 and broken away on line 3-3 Figure 16.
In Figures 20 to 29 inclusive, I have represented various devices for operating
the pan or clapper of a water closet and means for effecting a running water or
other seal therefor so as to hermetically seal the closet at all points. Figure 20
shews a detail section of gearing mechanism located in the chamber a7 of the
container A'; the sealing fluid from pipe a entering the said chamber a through
the perforations c c in the lid A³ of the container, as more plainly shewn in
Figure 21 which is a broken plan of the said cap.
Figure 22 shews a rack and pinion mechanism for the clapper A³, in this case
the container lid A' has an upwardly projecting tube surrounded by a cap secured
to the rack or its rod as indicated, the chamber a7 being secured to the said lid and
enclosing the said cap and tube. Into the chamber a leads the pipe a³ so that the
water or fluid therefrom passes to the chamber a³, rises therein, and seals the cap
attached to the said rack and passes into the container through the perforations co
in the said projecting tube and lid A' as more clearly shewn in the horizontal
section Figure 23. As the said rack is lifted to move the clapper A³, the cap
secured to the rack still remains sealed in the water in the chamber a7 as indicated
by dotted lines in Figure 22, so as to prevent the escape of gas from the container.
If desired, the chamber a', instead of being fixed and forming part of the
container A, may be separate therefrom and be secured to the journal of the
clapper pan or valve A³ so as to move therewith, such construction is shewn in
Figures 24 and 25. Or the said chamber a' may be dispensed with and the link
or operating rod a³ for the said clapper or valve, may pass through a stuffing box
on the container lid as shown in Figures 26 and 27. In which case the pipe a³
will connect with the stuffing box as represented, from which it is designed to lead
to the bowl or container as desired.
Instead of using the water seal for the said operating mechanism, a mercury seal
may be substituted therefor, as represented at a Figure 28.
In Figure 29 I have illustrated a modification of the device shewn in Figure 22.
The movable cap, secured to the rack rod in the latter, is in the former placed upon
the link as within the chamber a² and surrounds the depending tube of the
container lid as indicated.
In Figures 30 to 33 inclusive I have shewn means for effecting a running seal
joint or joints between the bowl and container for preventing the escape of sewer
gas and odours therethrough so as to still further hermetically seal the closet.
In Figure 30 the bowl A is formed with a flange d which dips into an annular
trough or depression d in the container lid A. On the latter is a flange d
entering a groove da in the top of the container A. The pipe a leads to the
groove d³ and the depression a through channels or ducts d' and thence to the
container.
In Figure 31, the flange d is dispensed with as is also the depression of lid Aª,
the container being provided with a lip, spout, or pipe d³ for conducting the water
from the groove d³ to the pan A³ to form a running seal for said parts
If desired the disinfectant reservoir B¹ shewn in Figure 32 may be connected
with the pipe a³ as above described or the said reservoir may be formed on the
container as shewn at z Figures 31 and 33.
In Figure 34 I have shewn the mechanism represented in Figure 22 applied to a
water closet to more clearly illustrate the arrangement of the parts of the same,
Figure 35 is a detail section or an enlarged view of Figure 23. Figure 36 shews a
clapper with a packing ring seating itself against the lower edge of the bowl
-

page_text: "
Figure 37 illustrates a modified form of disinfectant chamber and the water or
connecting pipes therefor. Figure 38 shews the improvements applied to a water
closet having a plunger or plug valve E. From the bowl A the overflow leads to a
point below the said valve E thereby providing a running water seal both for the
valve chamber and the bowl
In all the above described fixtures the running seal is employed to hermetically
seal them, but such result may be obtained without using such seal, or as shewn in
Figures 39 to 46 inclusive. Figure 39 being an elevation, partly sectional on the
line 2-2 Figure 40, which is a section on the line 1, 1 Figure 39. The container lid A'
in this case, is provided with the depending tube as above described, but such tube
has a flange, as shewn at e, upon the outside edge of which is placed a packing e¹
for the head of a cylinder e³ secured to the link or operating rod a³ for the lever a*
which moves the clapper or valve As and the cock a³. The push rod of the latter
as well as the operating lever a and other parts are all contained within the
chamber a of the receiver A'; consequently when the cylinder e² is down upon the
packing e, the only outlet of the chamber a' is sealed.
By such construction it will therefore be seen that the receiver or container is
thereby hermetically sealed without the employment of the running fluid seal. The
formation of the chamber a' in this case as well as the cylinder e² are more plainly
shewn in Figure 41 which is an enlarged sectional view of the said parts.
Figure 45 is a section on the line 4-4 and Figure 46 a section on the 5-5 of
Figure 41.
In Figure 42, the packing e¹ is shewn placed in a recess in the container or
receiver lid A' and the cylinder e³ is exterior to the container; Figure 43 is a
section on the line 3-3 Figure 42.
If desired an ordinary valve D2 Figure 44 may be substituted for the cylinder e².
If the latter is used, as shewn in Figure 39, it may if desired be filled with water,
mercury, or other suitable fluid, in order, that when the rod as is raised the end of
the depending tube on the lid A2, is sealed by such fluid during such ascent.
Figures 47 to 49, inclusive show a water closet with upper grooved edge and
sealing cap provided with a disinfectant chamber B', the latter in Figure 47, being
exterior to the closet, while in Figures 48 and 49 such chamber is formed on the
closet bowl and the pipe a leads to the water pipe a³. In the latter case a running
disinfectant seal is provided, and in the former the seal may be running or inter-
mittent, as desired, and regulated by the cock in the pipe aº.
In Figures 50 and 51, devices are shown connected with the closet push rod for
introducing the disinfectant Huid into the closet during the flushing of the same.
In Figure 50 the cock b³ is operated by means of collars formed on the push rod a³
as shown, so that, when the latter is raised, the said cock is opened, and the
disinfectant from the reservoir B flows into the container as the bowl is being
flushed. In Figure 51 the pipe a instead of passing directly to the bowl, leads to
a second reservoir B2 and from the latter the pipe a is designed to be continued to
and leads either to the bowl or container, but the bore of the latter portion of the
said pipe is smaller than that of the former, so that the disinfectant will flow more
rapidly into the reservoir B than it will flow out thereof; consequently when the
closet is flushed and the valve be opened as above described a charge of disinfectant
remains in reservoir B to flow out thereof to the container or bowl after the latter
is flushed. By such construction and operation the full available advantage
intended to be derived from the use of the disinfectant is obtained
In all the foregoing described constructions where a running water or fluid seal
is used for the closet or fixture, the pipe a³ or a branch of the water supply pipe a
is employed to provide for such seal. But, if desired, such result may be obtained
by making a perforation in the valve of the cock a³ as shown in Figures 52 to 56
inclusive, Figure 52 showing a sectional view of the cock and an elevation of the
closet bowl and flushing pipe. The valve F of the cock a³ has a perforation as
indicated at f, or it may be formed in the partition f¹ of the said cock as shown in
Figures 54 and 55 or in its casing as represented in Figure 53, or the valve stem

page_text: may have a stop f² thereon to prevent the valve F closing upon its seat so as to
form a chamber or perforation between the said valve and its seat or the partition f'
as indicated in Figure 56. Such perforation, however formed, provides for a leak
in the cock a or for the passage of a small stream of water therethrough when
closed. Such water finds its way through the flushing pipe A and thence to the
bowl, and provides for the running water seal therefor.
In Figures 57 to 68 inclusive, I have shown the running water seal, the disin-
fectant seal and the flushing mechanism applied to sewers or their inlets, various
constructions of traps being represented for the said inlets.
In Figure 57 the inlet G has a sealing groove g and a cap g' to which are
attached screens g₁ to catch and prevent refuse matter passing to and filling up
the groove, g, a horizontal section of the latter, cap g₁ and inlet is shown in
Figure 58.
The continuous water supply pipe a³ may be attached to the inlet as shown at g³
or as indicated at g'. If desired it may have a disinfectant reservoir B¹ as indicated
by dotted lines Figure 57, to which leads a pipe from the main supply pipe a³ or
other source of supply. The reservoir B' may be secured to or within the inlet G
as shown in Figures 59, 60, 61 and 66 and, if desired, an additional pipe or pipes a³
may lead into the sewer as represented in Figure 61.
In Figure 62 a tilting flushing tank G¹ is provided for obtaining an intermittent
running seal for the trap of the inlet which in this figure, is shown provided with
an ordinary partition trap. Or, instead of using a tilting tank a float may be
substituted therefor as shown in Figure 63, in which the pipe a³ is also shown
leading to an exterior disinfectant reservoir B¹.
In Figure 64 the pipe a' is connected to chamber B₁only, so that the latter is
made of such extent that it will hold sufficient liquid to provide for intermittently
flushing the inlet trap by opening and closing the cock 65
Figures 65 and 68 show a trap for the inlet similar to that shown in Figure 57,
but the cap g¹ is unprovided with the screens g³.
In Figures 66 and 67, the inlets have partition or P shaped, traps and in the
latter figure I illustrate the manner in which the running water or fluid seal
equalizes the back pressure in the sewer, by rising in the sewer on the induction
side of the trap when it cannot pass therethrough owing to the back pressure of
gas upon the eduction side of the trap.
As such pressure diminishes, the hydrostatic pressure correspondingly lessens
until the seal is restored to its normal condition.
If desired the continuous flow from the pipe a³, may be sprayed or atomized as
it passes into the inlet, as shown in Figures 57, 60 and 61.
Another part of this invention consists in cleansing the traps of water-closets
and the like, of all adhering fecal matter without removing them from their
location. To properly and effectually accomplish such result it is advantageous
that the frame or wood work of the closet should be hinged, or secured together so
that it can be unfolded from the closet. I prefer to so construct the closets but it
is not essential so to do, as the cleansing operation may be performed without
disarranging or removing such frame-work.
"
In Figures 69 to 74, inclusive is shown a removable or "knock down" frame
for the closet, the sides and top being hinged or pivotted to each other as shown.
Figures 69 and 70 illustrate the frame closed or in position around the closet, the
dotted lines in said Figures showing such frame in an open or
"knock down
condition. Figure 71 is a plan, Figure 72, a perspective view of the sides of said
frame, Figure 73 a perspective view of the seat therefor and Figure 74 a detail
section of a thimble for the removable screws used in holding the frame in a closed
position the said screws being shown at a Figure 70.
When the traps are to be cleansed the said casing or frame is unfolded or opened
and a flexible shaft H carrying ball clustered bristles as shown in Figure 75, or
circular brushes as shown in Figure 80; is inserted into the trap as illustrated in
the said Figures. The flexible shaft H with its bristles or brushes conformis to

page_text: the outline of the trap and impinges against its sides so that when the said shaft
is reciprocated by an air, a steam or other motor I, Figure 75, or by the bevel
wheel and screw mechanism, Figure 76; or by the lever mechanism, Figure 77 the
said brushes rub against the sides of the trap and cleanse them of all adhering
matter. After which a flow of water is passed through pipe h' to flush or wash the 5
said brushes and the trap.
.
Instead of using a series of brushes, only one brush may be used, in which case
it is connected to a shaft h upon which is secured a propeller h³ designed to be
revolved to correspondingly move the brush, by means of a flow of water from
the hollow shaft H' to which the said brush and propeller is attached, such 1
construction is shown in Figure 78 and a plan of the brush is represented in
Figure 79.
If desired, the shaft H may be of lead, or composed of links as represented in
Figures 80, 81 and 82; or of a hollow. rubber tube as indicated in Figure 83, or it
may consist of a spiral spring or coil having a perforated covering to which the 1
bristles are attached as represented in Figures 84 and 85.
Instead of using the brush and shaft a flexible perforated tube may be employed
and water or other fluid forced under pressure, therethrough, so that as the said
water emerges from the perforations in jets it will remove the adhering fecal
matter from the trap by the force of impact.
Such water may be forced into and through the perforated pipe by a pump or
other suitable mechanical means, but I prefer to use compressed air or gas for that
purpose, accordingly in Figure 86 is shown an apparatus consisting of two
reservoirs K, K¹ with intervening pipe connection and an outlet k¹ having
cocks k³ and ³ respectively. The reservoir K is filled with compressed gas, and the
reservoir K¹ with water, so that by opening cocks k³, ³, the expansive force of said
gas will act to force the water from the reservoir K through the pipe or hollow
shaft k into the closet A; the said pipe is provided with a cover for the closet to
prevent splashing.
If desired the said pipe ¹ may terminate in a spraying or atomizing device L.
Again instead of using two reservoirs only one need be used which contains
water or fluid as indicated by dotted lines 9-9 Figure 86, upon which the gas is
compressed in the remaining unoccupied part thereof. In such case, the pipo kis
not used and the outlet is secured to the reservoir K' and may if desired be
provided with a sprayer L' as shown.
Figures 87 and 88 show the pipe connection k with a cover applied to a wash-
basin and bath-tub respectively for cleansing their traps or soil pipes.
It will, therefore, be noted that this invention comprises a water closet or other
like fixture which is hermetically sealed at all points, wherein the sewer gas is
absorbed and the seal therein maintained by a running stream or flow of water
which seal may if desired consist of a disinfectant fluid continuously or inter-
mittently injected therein; of a casing or frame for the closet which is removable
therefrom and of means for effectually cleansing the inner wall of the closets and
appurtenances, whereby such fixtures are not only rendered inodorous but
maintained in such condition that sewer gas cannot escape therefrom or vegetable
organism be given off thereby.
Having thus fully described the said invention as communicated to me by my
foreign Correspondents and the manner of performing the same I wish it understood
