Improvements in and relating to Traps for Water-closets.
I, GEORGE MICKLE DICKISON, of the firm of Alexander Dickison, and Sons,
Plumbers and Sanitary Engineers, of 2 Brougham Street, in the City and County
of Edinburgh, and WALTER BRODIE, Practical Manager, to said firm, do hereby
declare the nature of our invention to be as follows:-
This Invention has reference to and comprises improvements in and relating to
the construction and fitting of siphon traps for jointing under or to the pans of
water-closets, and which will be stronger and safer against breakage, and leakage
of the gases or liquids, than such traps have been as heretofore constructed.
The nature and novelty of the improvements consist in constructing these siphon
traps, whether made of the S or the P type (that is with the discharge pipe
vertical or at an angle from the overflow discharge bend) of cast iron with a flat sole
piece on the under side of the first lower bend for resting on the foundation plate of
the closet, and carrying the whole, and with a flat piece on the upper outer part of
the second bend for the pan of the closet being rested and steadied on, the discharge
spigot of the closet pan being jointed to the faucet on the upper part of the entering
branch of the trap.
A further improvement consists in forming the discharge branches, whether vertical
or at an angle, with flanges for jointing to the discharge drain pipes, by corre-
sponding flanges, and screw bolts, and india rubber or other insertion ring joints
between the flanges. And further in forming the ventilating or cleaning branch of
the trap, whether attached to the siphon or to the first discharge branch of the siphon
also with a flanged joint and ring flange, for jointing the lead branch of the venti-
lating pipe to by a corresponding flange and screw bolts and putty insertion or other
joint. These flange joints within the house would have the advantage of making
perfectly tight joints, with the certainty that no gas could escape into the house
from the discharge or drain pipes, besides making it easy for the fitting of the parts
of traps and their branch pipes to each other, for removal or cleaning; and in frosty
weather prevent the cracking of these siphons by the freezing of the water within
them as is frequently the case with porcelain siphon traps. The joints outside of
the house however might where found desirable be made with ordinary spigot and
faucet joints to the ordinary earthenware drain pipes. In some cases these siphon
pipes and their branches leading to the vertical discharge pipes when so made all
of cast iron may have spigot and faucet joints formed with run in lead joints caulked
to make them more perfectly fluid tight, than is possible with the earthenware pipes
and branches heretofore used. A further improvement consists in coating these
siphon traps and discharge branches so made of cast iron, inside, or inside and out-
side with silicious enamel, or with indurate varnishes or japans, or coatings such as
the well known Doctor Smiths coating solutions, for preserving metals, or in
galvanizing them with tin zinc, or other metals or alloys.

Improvements in and relating to Traps for Water-closets.
We, GEORGE MICKLE DICKISON, of the firm of Alexander Dickison and Sons,
Plumbers and Sanitary Engineers, of 2 Brougham Street in the City and County
of Edinburgh, and WALTER BRODIE, Practical Manager, to said firm, do hereby
declare the nature of our invention, and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement in writing, reference being had to the accompanying Sheet of Drawings,
and to the letters and figures marked thereon, that is to say :--
This Invention has reference to and comprises improvements in and relating to
the construction and fitting of S sealed or siphon traps for jointing under or to the
pans of water-closets, and which will be stronger and safer against breakage, and
leakage of the gases or liquids, than such traps have been as heretofore constructed.
And in order that our said Invention, and the manner of performing or carrying
the same into effect or practice may be properly understood, we have hereunto
appended an explanatory Sheet of Drawings, in which the same reference letters
are used to indicate corresponding parts in both figures where shown. Figure 1
is a sectional elevation of an S-shaped siphon trap A, A', and fittings as con-
structed in accordance with our improvements as applied to a water-closet
porcelain basin B, B¹, which flushes and discharges down the vertical branch B¹
in front, into the vertical inlet branch A of the trap, the water being supplied
at the back branch B2 of the basin, with an ordinary spreading
for
flushing the basin with water forward, this arrangement of the trap being shown
with a vertical discharge branch A2 for leading down by pipes into the common
discharge pipe of a number or block of houses or set of water closets leading
to the sewer. Figure 2 is a corresponding sectional elevation of our improved
siphon trap A, A1, as applied to a similar basin B, B', as that shown in Figure 1,
but as formed with an angular or P-shaped discharge branch A", and corresponding
branch pipe A³ in line for leading the discharge more directly through the vertical
soil pipe leading to the sewer, than in the arrangement shown in Figure 1.

Referring to these Drawings:-The improvements consist in constructing these
siphon traps A, A¹, and their discharge branches A2, A", whether made of the Sor
the P type, as shown in Figures 1 and 2 respectively, of cast iron, with a flat sole
piece at a on the under side of the lower or water bend of the trap for resting and
securing to the floor or foundation plate of the closet, and carrying the whole, and
preferably with a flat or curved piece at a¹ on the upper outer part of the second bend
for the pan part B of the closet to rest and be steadied on, the discharge spigot
branch B¹ of the closet pan being jointed by putty or other cement to the faucet a¹¹
on the upper part of the entering branch A and above the water seal of the trap.
A further improvement consists in forming the discharge branches A³, A", whether
vertical as shown at A2 in Figure 1 or at an angle as shown at A" in Figure 2, with
flanges a² for jointing to the discharge branches A³ A³, by corresponding flanges a³
and screw bolts, and india rubber or other insertion ring joints between the
flanges a², a³. And further in forming the ventilating or cleaning branch A* of the
trap A, A¹ whether attached or formed on the branch A2 or on the adjacent branch A³
of the discharge pipe of the siphon also with a flanged joint a', for jointing the lead
branch A of the ventilating pipe, generally led up to the roof, by a corresponding
flange on the lead pipe, and an outside ring and screw bolts and putty insertion or
other joint. These flanged oints a², a³, a², within the house have the advantage of
easily making perfectly tight joints, with the certainty that no gas can escape
the house from the discharge or drain pipes, besides making it easy for the fitting of
the parts of traps and their branch pipes to each other and to the basin B, B¹, for
removal or cleaning; and in frosty weather prevent the cracking of these siphons
by the freezing of the water within them as is frequently the case with porcelain
siphon traps. The joints outside of the house however might where found desirable
into

be made with ordinary spigot and faucet joints to the ordinary iron or earthenware
drain pipes. In some cases the branches A³ of these siphon traps A, A', might
have their branch joints leading to the vertical discharge pipes, when so made all of
cast iron with spigot and faucet joints as indicated in dotted lines at C in Figures 1
and 2, formed with run in lead joints caulked to make them more perfectly fluid
tight, than is possible with the earthenware pipes and branches heretofore used.
further improvement consists in coating these new or improved siphon traps A, A',
and discharge branches A2, A¹¹, so made of cast iron, inside, or inside and outside
with silicious enamel, or with indurate varnishes or japans, or coatings such as the
well known Doctor Smith's coating solutions for preserving metals, or in galvanizing
them with tin zinc, or other metals or alloys, for the purpose of preserving these
traps from corrosion or the accumulating of soil on their surfaces.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
First. The constructing of traps for water-closet basins of cast iron and coated
inside with silicious enamel or other indurate coating and fitting the same to the
basins, and to the drain and ventilating pipes substantially as and in the manner
herein described in reference to and shown in the accompanying Drawings.
Second. The constructing of traps for water-closet basins of cast iron with
flanges a² as or at at their discharge or ventilating branches respectively substantially
as herein described, in reference to and shown in the accompanying Drawings.
Third. The constructing of traps for water closet basins of cast iron coated insido,
or inside and outside, with silicious enamel or other indurate or metallic coating,
substantially as and for the advantages herein described.
