Improvements in Cast Metal or Earthenware Jaw-boxes, Sinks,
Troughs, Cisterns, Baths, and such like Vessels.
I, JOSEPH LOCKWOOD of 18 Vale View Terrace, Langside, Glasgow in the County
of Renfrew, Artist, do hereby declare the nature of this invention to be as follows:-
It is a plan, chiefly designed to prevent Sewer Gases obtaining access to dwellings
through the waste pipes connected with Sinks, Baths or other similar vessels contained
therein, and for other analogous purposes. This invention, though principally
intended for application to Cast Iron Jaw Boxes, consists in making Jaw Boxes,.
Sinks, Cisterns, Baths or vessels of a similar character thereto, whether made of Cast
Iron, Steel or Baked Clay; with a Stench Trap, of the particular character described
herein, as an integral part of the vessel itself, in place of the loose Stench Trap
commonly affixed to such vessels as an additional and not an integral part thereof.
It is applicable to all sanitary appliances resembling Troughs or Sinks that have an
uninterrupted and unventilated connection with drain pipes or Sewers and which
vessels are contained within covered places or buildings. The object being to
interpose, beyond the possibility of separation, a permanent Stench Trap, between all
such vessels and the sewer or drain into which the fluids passing through them are
discharged.
The particular character of the Stench Trap herein referred to is, that in place of
the Swan Neck" form, commonly employed in connection with Jaw Boxes and
Sinks, this Stench Trap is straight in its general form and resembles a horizontal
guiter permanently attached to (and cast, or moulded with) the under side of the
vessel, but intersected at two or more parts internally with vertical flanges, the lower
one of which, serves to form a dam, retaining always a supply of water or fluid in the
gutter whilst the upper flange projects downwards into, and below, the surface of the
water or fluid, and so forms the Trap.
This invention consists also in the particular characters of, and methods of attaching
to, the aforesaid stench trap, one or inore syphon outlets together with the requisite
plugs, plates, or covers for them.

page_text: This invention consists further in making such vessels with an open top to the
overflow pipe so that the latter may be cleaned out as required: the internal formation
of the said overflow pipe in this case being round, oval, or of such other form that
there are no acute angled joints to prevent cleaning or to retain dirt.
One particular and important item in this invention so far as it relates to cast metal
Jaw Boxes is that all sharp corners are avoided when joining together any angled
parts. The joints between all such angled parts are made of a concave.or curvilinear
form on that surface of the article which is exposed to the action of water or other
fluids in order to prevent the secretion of dirt in the various corners of the vessel and
assist in the removal of anything likely to stagnate and produce an offensive odour
after the vessel has been used. For this purpose the overflow pipe is here made like
an oval or round tube (instead of a rectangular one) in both cast metal or
earthenware Jaw Boxes. The rectangular form of joining angled surfaces being
everywhere avoided and the Concave & Convex being substituted; that is, that the
Concave surface of such joints is the inner one and is exposed to the action of the
fluids and the Convex surface is the back or outer surface thereof.
A further item in this invention is the provision of holes or slots in the marginal
flanges of Jaw Boxes or Sinks whether they are made of cast metal or baked clay by
forming them in the mould from which the articles are produced, in contradistinction
to drilling them therein after the article, has been made. The said holes or slots being
intended for fastening purposes.
The vessels to which this invention applies, when made of Cast Metal, may be
galvanized, Electro-plated or Enamelled.

page_text: Troughs, Cisterns, Baths, and such like vessels.
I, JOSEPH LOCKWOOD of 18 Vale View Terrace, Langside Glasgow in the county of
Renfrew Artist do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
It consists of improvements which are designed, chiefly, to prevent sewer Gases
obtaining access to dwellings through the waste water pipes connected with Jaw Boxes,
Sinks, Baths or other similar vessels, contained and used in such dwellings, and for
other analogous purposes (including, amongst others, provisions for cleaning out the
waste water channel, or channels, of such vessels).
This invention, although principally intended for application to Cast Iron Jaw
Boxes, consists also in making Steel or Earthenware Jaw Boxes, Sinks, Cisterns,
Troughs, Baths or vessels of a similar character thereto, (as well as Iron ones,) with
an inseparable Stench Trap, (of the particular character and forms described herein),
as an integral part of the vessel itself; such inseparable trap being in place of the
separable Swan Neck trap commonly affixed to such vessels, and which swan neck trap
was, prior to my invention, an additional, attachable & separable trap, in contra-
distinction to its being an integral part of the vessel itself.
It is applicable to all sanitary appliances, resembling Troughs or Sinks, that have
an uninterrupted and unventilated connection with drain pipes, or sewers; and which
vessels are intended to be contained, and used, within covered places or buildings.
The principal object, which I have in view, being to interpose, beyond the possibility
of separation, a permanent stench trap between all such vessels and the sewer, or
drain, into which the fluids passing through them are discharged; and, secondarily to
make the addition of stench traps to such vessels cheaper than hitherto, more
convenient of access for cleaning purposes, and less destructible or liable to injury
than the swan neck stench traps (commonly used therewith and) made of soft metal.
The particular form and character of the stench trap herein referred to, is, that in
place of the Swan Neck form commonly employed in connection with Jaw Boxes and
Sinks, this stench trap is made straighter in its general form and resembles, in certain
varieties, a horizontal trough or gutter; it is also (or may be) permanently attached
to, forms part of, and is cast or moulded with, the underside of the vessel with which
it is associated; and is, (or may be) internally intersected, at two or more points, with
vertical flanges of the character of Baffle plates, one of which flanges serves to form
a dam, for retaining a supply of water, or fluid, in the said dam, trough or gutter,
whilst the other, (upper), flange, (or flanges), project downward into, and below, the
surface of this water or fluid, and thereby form the stench trap. Although preferably
cast with, or moulded upon, the vessel with which it is associated, this stench trap
may, in special cases, be detachable from, and replaceable upon certain of such vessels.
This invention consists, also, in the particular characters of, and methods of attaching

page_text: to the aforesaid vessels, (or appliances), one or more plugs, (plates, or covers) to
apertures which are provided in the said vessels for affording easy access to the
stench trap and its associate waste water channels, (or pipes), for cleaning and other
purposes.
This invention consists further, in making such vessels with an open top to each
overflow pipe thereof of such size, kind and accessibility that the said pipe, (or pipes),
may be cleaned out thereat as often as required; the internal formation of these
overflow pipes being, generally, round, but may also be oval, or of such other form
(internally) that there may be no acute angled joints within such channels to prevent
cleaning or to retain dirt therein, whenever such acute angles can be avoided.
One particular and important item in these improvements, consists in making cast
metal Jaw Boxes so that all sharp corners are avoided when joining together any
angled parts. These said joints are made of a concave or curvilinear form, on that
surface of the article more especially, which is exposed to the action of water or other
fluids in order to prevent the secretion of dirt in the various (necessary) corners of
the vessel, and assist in the removal of anything likely (otherwise) to stagnate there
and produce an offensive odour after the vessel has been used. In furtherance of this
purpose, the ordinary (end) overflow pipe is, in my invention, made (internally) like
an oval, elliptical or round tube (instead of a square or sharp angled rectangular one)
both in cast metal and earthenware Jaw Boxes. All acute or sharp corners, when
joining angled surfaces, being, in every possible instance, avoided, and the concave
and convex form being substituted; that is, that the concave surface of such joints
constitutes the inner one, and is exposed to the action of the fluids, and the convex
surface is the back or outer surface thereof.
A further item in this invention, is the provision of holes or slots in the marginal
flanges of Jaw Boxes, or Sinks (whether the said vessels are made of cast metal or
Baked clay) by forming the said holes by means of, and with, the mould from which
the articles are produced, (in contradistinction to drilling them, in the metal ones,
after the said articles have been made).
The accompanying series of diagrams will serve to illustrate my invention and
enable it to be better understood and more readily carried into effect. Similar letters
and numerals refer to corresponding parts throughout the illustrations.
Fig. 1 is a perspective view of that portion, only, of an ordinary cast metal
Jaw Box, which contains the outlet gratings, and the round lid, or cover, for that
grating which is sunk below the bottom, (and inner), surface of the vessel.
Fig. 2 is a perspective view of the parts which are underneath those shewn in Fig. 1,
giving the external form of the overflow and waste water pipes of an ordinary
cast metal Jaw Box (such as was commonly made prior to my invention); The
Jaw Box is here shewn in inverse position; that is, not in its natural position.
Fig. 3 is a sectional elevation, of parts contained in Fig. 2, and shewn in the inverse
position similar to Fig. 2.
Fig. 4 is a perspective view of that portion only of my improved cast metal
Jaw Box, which contains the parts corresponding to those of an ordinary Jaw Box,
which are shewn in Fig. 1.
Fig. 5 is a perspective view of those parts of a Jaw Box which are, in certain
variations of my invention, underneath those which are shewn in Fig. 4.
Fig. 6 is a sectional elevation of parts contained in Fig. 5; the said parts being
here shewn in inverse position, similarly to the underneath view given in Fig. 5.
Fig. 7 is a plan shewing the interior of my improved Jaw Box, fitted with, hinged
and otherwise removeable, covers for the waste water outlets thereto, which outlets
consist of the grating in the bottom, the overflow pipe at the end and the faucet
underneath the vessel, the cover here shewn to the end overflow pipe being, in this
view, hinged to the vessel, and of such a form that when it is closed over the
aperture, I, it leaves only small holes, resembling a grate, for the escape of surplus
water or fluid, from the trough of the vessel into the said (end) overflow pipe. The
holes, for fastening purposes, which are comprised in my invention, are shewn, in this
view, upon the marginal flange surrounding the upper edge of the vessel.

page_text: Fig. S is a plan, (similar to Fig. 7.), shewing the interior of my improved Jaw Box,
with the cover, J, for round, bottom grating removed therefrom and placed in the
circular cavity, T, shewn in Fig. 7 also shewing the open top and exit grating of
the end overflow (or waste water) outlet without any (hinged or other) cover thereto,
and with a slightly different shaped covering plate (to that shewn in Fig. 7) for the
waste water faucet (and stench trap) which are beneath the vessel.
Fig. 9 is a longitudinal section of my improved Jaw Box, shewing one method of
screwing to the body of the vessel, the round waste water grate (combined with one
or more flanges.depending from its under and outer surfaces) and the cover for
affording access, (from the inside of the vessel) to the stench trap and waste water
pipe, which are beneath the vessel. The end overflow pipe which is shewn in this
view, has an open top similar to that shewn in Fig. 4.
Fig. 10 is a longitudinal view of a Jaw Box, in perspective, (and partly in section),
shewing the application of certain of my improvements thereto, namely, a cross bar
and screw attachment, supported upon flanges contained within the waste water faucet
underlying the vessel, for the purpose of retaining the covering plate of the stench
trap and, (said), faucet, firmly in its place, the screw and loose, (wing), nut associated
with the round water grate and the stench trap, (which underlies the said grate), for
securing the nether covering plate, to the aperture provided within the base of the
said stench trap. This view also shews the marginal holes for fastening purposes, the
hinged, (and grated) cover to the end overflow pipe, and (a well known) chain
attachment for the round grate cover.
Fig. 11 is a longitudinal view, in section, of my improved Jaw Box, (similar to the
view given in Fig. 10) but without any of the covering plates or the members for
securing them to the Faucet, Round waste water grate or the syphon (nether) outlet
provided in the base of the stench trap. This view shews a removeable (loose) cover
to the end overflow pipe, and a view of the same (cover) in perspective, detached
from the vessel.
Fig. 12 is a longitudinal and sectional view of my improved Jaw Box, similar to
the foregoing view (Fig. 11.) but with covering plates, (and their associate members
for securing the same) to the Faucet and Stench Trap and the hinged cover to the
end overflow pipe, all in their relative positions.
Fig. 13 is a longitudinal and sectional view of my improved Jaw Box, similar to
Fig. 12, but with the addition of a cover to the waste water grate. The waste water
grate, in this view, is shewn detachable from the Jaw Box, and replaceable, being
retained in its place by means of the screw and nut which are used for uniting the
cover plate to the aperture, (or syphon hole), in the base of the stench trap.
Fig. 14 is a longitudinal and sectional view of my improved Jaw Box, (similar to
Fig. 11), but with the addition, in this view, of a cavity, above the waste water grate,
for the reception of a cover; the water grate, in this view, being shewn removeable.
Fig. 15 is a longitudinal and sectional view of my improved Jaw Box, shewn with
the removeable waste water grate screwed to the interior of stench trap, (underlying
the said grate), a removeable cover for affording access, (from above); to the
stench trap and the waste water faucet outlet therefrom; balance claw for securing
the said cover plate to the said faucet, and a Hinged cover to the end overflow pipe.
Fig. 16 is a transverse sectional elevation, (through A B of Fig. 15), shewing my
improved Jaw Box, with end overflow aperture and lid, together with the Balance Claw
appliance for securing the cover plate of the waste water faucet in its place.
Fig. 17 is a longitudinal and sectional view of my improved Jaw Box, shewn with
thick body to represent earthenware. The waste water grate is, in this view,
represented to be removeable (from above) and forms a seat for the head of the screw,
which retains the nether covering plate (for the syphon aperture of the stench trap)
in its place. The said grate furnishes a scat also for the cap, or cover, for itself. The
upper cover for affording access to the stench trap and waste water faucet, (underlying
the vessel), is shewn, in this view, to be retained in its place by means of a sliding
bolt, (or tongue attached to a sliding member), and which bolt is accessible through
the stench trap, when the latter is opened.

page_text: Fig. 18 is a sectional view of the stench trap and other parts, similar to those
shown in Fig. 17. The waste water grate is here shewn as a part of the earthenware
vessel, and is not removeable.
Fig. 19 is a plan of the stench trap, (through C, D Fig. 18), with faucet and syphon
outlets thereto, and slewing the sliding member, (or bolt), for securing the faucet
cover to its seat.
Fig. 20 is a sectional view, resembling Fig. 18, but representing the sliding bolt
and tongue drawn back, suitably for releasing the faucet cover.
Fig. 21 is a longitudinal and sectional view of my improved Jaw Box, with the
stench trap formed by means of a trough or channel encircling the upper part of the
waste water faucet, (together with an associate Bell, or dome cover, attached to the
under side of the faucet cover plate), instead of the trap being formed by means of a
longitudinal trough and baffle plates, (or flanges), on one side only of the faucet pipe,
(as shewn in Figs. 6 to 20). The waste water grate and its plug, (or cover) are
contained within the cover plate of the waste water faucet, and the flange for retaining
the cross bar screw appliance, is on the outside of the said faucet, (but within the
stench trap), in place of being formed within the interior of the waste water pipe.
Fig. 22 is a perspective view, shewing the upper end of the waste water pipe for
the stench trap, (shown in Fig. 21), with an external marginal flange to the pipe, and
with a small slot and surface grooves, for assisting the adjustment, and retention, of
the cross bar screw appliance.
Fig. 23 is a perspective view, similar to Fig. 22, but with a cross bar screw
appliance shewn in its position, suitably for use.
Figs. 24 and 25 are perspective views of cross bar screw appliances.
Figs. 26 and 27 are perspective views of cross bar screw appliances, containing
screw holes, but not screws..
Figs. 28 and 29 are perspective views of waste water faucet covers, for my improved
Jaw Box, which covers, (here shewn), contain screws; for insertion within cross
bars such as those shewn in Figs. 26 27 or 35.
Figs. 30 and 31 are sectional views of Figs. 28 and 29.
Figs. 32 and 33 are perspective views, of parts similar to those shown in Figs. 22
and 23, but with an internal, (instead of an external), flange around upper margin
of waste water pipe.
Figs. 34 and 35 are perspective views of cross bar screw appliances, for use with an
internal marginal flange, such as shewn to Figs. 32 and 33.
Fig. 36 is a longitudinal and sectional view, of a shallow sink, furnished with a
stench trap and removeable cover, (which cover contains a waste water grate and its
plug), same as that shewn in Fig. 21, (excepting the overflow pipe, which, in Fig. 21,
serves a purpose which is not required in a shallow sink like Fig. 36).
Fig. 37 is a longitudinal and sectional view, of a metal sink, fitted with a Bell trap,
formed by a dome, beneath the waste water grating, and a channel encircling the
outside, (upper), end of the waste water faucet pipe. Such sinks being commonly
made and known prior to my invention.
Fig. 38 is a view of a stench trap resembling the one shewn in Fig. 36, but
detachable. The screw, shewn to the cross bar screw appliances in the illustrations
described above, may be either altogether loose, and separate from either the cross
bar or faucet cover, or may be cast in the metal cross bar, or the metal cover, and, in
the case of Earthenware vessels, the cross bar screw appliances may be made entirely of
earthenware, or, partly of earthenware and partly of metal.
In the foregoing illustrations E represents the small overflow grating, which,
previous to my invention, was the only aperture afforded for cleaning out the end
overflow pipe,. (E³), of either cast metal or carthenware Jaw Boxes, (or similar
overflow pipes associated with Troughs, or such like vessels) which were used, or
intended for use, within covered premises. The part marked 1 is the water channel
underlying the waste water grate, H, (Figs. 1 and 3). The opening marked,
(Figs. 4. 6. 7. 8. 9. 10 and others), represents the open top to the end overflow pipe,
which open top, I have substituted in lieu of the grate, E, or in addition to it,
F.
}

page_text: (see Fig. 8). The trough marked F, (Figs. 6. 9. 10. 11. 12 andothe rs), constitutes
part of the stench trap in lieu of the waste water channel, E, (Fig. 3). The
passage, F³, is the end overflow pipe similar to E. The part marked G, is the waste
water faucet underneath the Jaw Box; H the outlet grating in the Bottom of the
said vessel, and J the loose cover for the said grating. K, and L, indicate the
marginal holes, and slots, for fastening purposes; M, upright and pendant flanges for
forming the stench trap; N the nether covering plate for syphon outlet to the
trough is the screw which passes through the grating, H. and cover plate, N,
and retains the latter in its place by means of the screwed, (wing) nut Q. The cover
plate, R, (Fig. 7), is to afford access, (from above), to the stench trap (and the wasto
water faucet, G, with its associate drain pipe or sewer) for cleaning and other
purposes; and this particular form (or any unreversible character) of cover plate,
(of whatever form.) is more especially adapted for association with such fastening
appliances as Z, and Z2, (Figs. 15. 16. 17. 18. 19 and 20); whilst the corresponding
cover plates S to S, (for same purpose as that marked R) are more especially
adapted for combination with such fastening appliances as those marked V to V³,
(Figs. 10. 12. 13. 21 to 36). The cavity, marked T is provided in the interior of the
vessel, for depositing the cover plate J therein, when the latter is not required to
cover any of the gratings marked H to H; whilst U to U indicate a hinged, or
otherwise removeable, (partial) cover for the end overflow pipe, F³, at the upper part
marked F. The letters V, to V3 represent loose and removeable cross bars, of different
forms, but similar in method of operation, containing either a screw, or a hole for the
reception, (or retention), of a screw, as shewn in Figs. 10. 13. 21 to 38. These cross
bars are constructed with slots, grooves or claws, as shown in Figs. 10 to 38, at their
extreme ends, for enabling them to be fitted upon the flanges W, W³, or W³ (Figs.
11 to 38). It will be seen, in and by, Figs. 10 to 38, that these cross bars (V to V³)
are for the purpose of attaching, and securing, the cover plates S to St such union, of
the covers and cross bars, being effected by means of the screw, or screws, associated
with them. The cover plate S³, and the Hanged grating H2, are united to the bed
of the vessel, by means of screwing them thereto as shewn in Fig. 9. The parts
marked S2 and S, (Figs. 21. 36 and 38), represent covering plates, (for the stench
trap overflow pipe G), which have domed or Bell shaped covers, (S6 and S°)
underneath them, for contributing to make a stench trap of a slightly different
design to that which is shewn in Figs. 6 to 12, and others. The orifice, (or opening) X,
is the aperture described as the "syphon outlet," for cleaning out the stench trap, F2,
and Y, denotes a Boss for containing, or receiving, the screw which unites the cross
bars, to V3, to their respective cover plates; the boss, Y, may be on one, both or
either side of the cross bar, as shewn in the various representations, of it, and the hole
within the said boss may be either plain, or threaded for screwing. The members
marked, and Z2, represent different methods, and means, for fastening an
un-reversible cover plate, such as that marked R, in Fig. 7. Various forms of
removeable waste water grates, for the base of the vessel, are indicated by the letters
and numerals, H³, to H³; (Figs. 13. 15 and 17). An overflow grating, marked 14,
(Fig. 8), may be used in addition to the open top, F, (provided for cleaning out the
end overflow pipe F³), instead of the "cut-away form, of open top, F, which is
shewn to Fig. 4; or the removeable covers, U2, 03 or U may assist in forming a
grated aperture for the overflow pipe, near the part marked F, or such a grated
aperture, (for Jaw Boxes or similar deep vessels), may be provided, (by any of the
appliances herein described which are most suitable for the purpose), at the point of
overflow from the stench trap into the drain, or within the faucet G; this grating,
wherever used, being for purposes of filtration, or preventing large particles of solid,
or semi-solid matter, obtaining access to the drains, and causing obstructions there.
Cast Metal Sinks, having a
Bell trap "
on the under side of, or beneath the waste.
water grating thereof, as shewn in Fig. 37, have been well known prior to my
invention; the said "Bell Cover being united to the grating, and they, together,
being removeable from above the pipe G I do not therefore claim to be the
inventor, broadly, of cast metal (shallow) sinks (such as shewn in Fig. 37) with stench
31
::

page_text: traps of this "Bell" form, nor of cast metal sinks or Jawboxes, (generally), with
an unremoveable and inseparable stench trap, of the same material as, and formed as
an integral part of, the said vessels, because I understand that Jaw Boxes have,
previous to my invention, been made with a "Swan Neck," or bent form of stench
trap, united to the vessel, and made, or cast, therewith, as an integral part of it; but
such stench traps have never been made, to my knowledge, of the convenient form
and character, (and fitted with such appliances for making them accessible) for
cleaning out, as mine. There are four points of difference (and improvement) between
my cast metal combined sink and stench trap, as shown in Fig. 36, and that shown
in Fig. 37. In such a cast metal, combined sink and stench trap, as that shewn in
Fig. 37, the cast metal faucet, or waste water pipe, 62, has never, to my knowledge,
been made more than one and a half inches in its internal diameter, and did not,
owing to its small diameter, afford sufficient space for examining, or doing necessary
work, through the said fancet, G2, to the drain pipe or sewer, connected with it.
My first improvement, therefore, in a cast metal combined sink and stench trap,
consists in the enlargement of this pipe, (G2 Fig. 37), to such dimensions, that any
ordinary man's hand may be fully inserted, (through it), into the drain pipe, (or
sewer), beyond it, in order to do any necessary work thereto, or remove obstructions
therefrom.
My second improvement in a cast metal, combined sink and stench trap, consists in
uniting with the Bell trap, (constructed similarly to, but not exactly like, that shewn
in Fig. 37) the cross bar screw appliances, such as those shown to the Jaw Box stench
traps herein, and illustrated by, and in, Figs. 36 and 38; by means of which
appliances, the waste water grating and Bell Cover, (whether composed of one
indivisible casting, or of more than one casting united together, or operated separately)
may be screwed down into their places, so firmly, yet removeably, that inexperienced
or mischievous persons may not be able, (too easily), to remove them, as they
frequently do remove similar covers when they are not secured to the vessel. It is an
advantage, and an improvement, to have such covers casily removeable by efficient
persons, and at the same time capable of firm attachment to the vessel, and I have, in
my second improvement, endeavoured to meet this requirement, in the manner shewn
in the drawings hereto, (Figs. 36. 38 and others).
My third improvement in a cast metal, combined sink and stench trap, consists, in
making the waste water grate within a cavity, contained in the cover to which the
dome or bell is united, and so constructing this grated cavity, that a plug or cover
may be inserted, (when required), for the purpose of retaining the water, or other
fluid, within the trough of the sink, for cooling, soaking Bathing, or other useful and
necessary purposes:
4
This latter appliance, (the sunk grate and its cover), and the qualification arising
therefrom, for such purposes as just described, have never, (before my invention
thereof), to my knowledge, been associated with shallow, cast metal sinks, although
commonly associated with Jaw Boxes; and although sinks and Jaw Boxes are alike
used, and designed for use, in sculleries, washing houses and such like places, they
are not identical articles, or described by the same name, but are always distinguished
by the two names which I have used in referring to them, both by the makers and
the users thereof.
My fourth improvement, in a cast metal combined sink and stench trap, consists, in
making holes, for fastening purposes, in the margin of the flange surrounding the
vessel, by means of, (and with), the mould in which the said sinks are cast; the said
holes, or slots, being similar to those described and shewn in connection with Jaw
Boxes, (Figs. 4, 5 and others).
Such a combined sink and waste water faucet pipe, with stench trap gutter
encircling the upper, (and outer), margin of the said pipe, as shewn in Figs. 36 and
37, has never, (hitherto), been made within my knowledge, in Earthenware of any
(Brown, White, Cane or other) kind.
I do not therefore, make the same limitation (to my invention), in relation to
earthenware sinks combined with stench traps, as I do to those made of cast metal.
