PROVISIONAL SPECIFICATION left by the said William Dundas Scott-
Moncrieff and William Dodds at the Office of the Commissioners of Patents on
the 3rd November 1882.
WILLIAM DUNDAS SCOTT-MONCRIEFF, of Fulham, and WILLIAM DODDS, of
Westbourne Park, both in the County of Middlesex, "IMPROVEMENTS IN VALVE
APPARATUS FOR SUPPLYING BATHS AND OTHER APPARATUS WITH WATER, AND
AVAILABLE FOR ADMIXING OTHER LIQUIDS,"
This Invention relates to certain improvements in valve apparatus for supplying
baths with hot and cold water or with water of any intermediate or required
temperature, and which improved valve apparatus is also applicable to other
apparatus in which different liquids or water or other liquids of different tempera-
tures are required to be adinixed; and the Invention has as principal objects, to
greatly simplify the arrangement of valve apparatus necessary to supply hot and
cold water or water of any required temperature to plunge, spray, douche, wave,
and other forms of baths, or to admix different liquids or water or other liquids of
different temperatures in other apparatus, and to dispense with a considerable
portion of the usual plumbing work, and to render the whole arrangement easy to
put together and to take apart.
According to a very advantageous modification of the present improvements,
there is used a form of valve known as a screw down stool or pillar valve, the
casing of which is according to these improvements, made with two lateral branches
or through ways at right angles to a branch or through way which is at the rear of
the casing and in alignment with the valve spindle. One of the lateral branches is
threaded externally, and the other is correspondingly threaded internally, or these
branches are otherwise conveniently and interchangeably formed so that any number

page_text: of them may be screwed or otherwise suitably coupled or connected in through
communication.
.
The improved arrangement of valve apparatus suitable for the purposes herein-
before indicated consists of such a connected arrangement, with the terminal lateral
branches suitably closed by a plug, cap, or otherwise. The rear branches of any
two (or more) of such a connected series of valve casings (but preferably of two
adjacent valve casings at one end of the series) form or serve as inlets for the hot
and cold water respectively or for the different liquids or for the liquids of different
temperatures, and thus on the spindles of these valves being turned, the water or
different liquids can be admixed to or in any desired temperature or proportions,
and then freely flow througli and into all the said valve boxes and their connecting
lateral branches. The rear branches of the other valve casings serve as outlets,
from any one or all of which, upon turning or raising the relative valve or valves,
the admixed water or liquids can be discharged or allowed to escape through
separate pipes to the plunge, douche, shower, wave or other baths or to where
else required.
In addition to the improved construction of valve apparatus being thus especially
serviceable for connection in a series, they are separately serviceable for various
analagous uses.
According to another modification of the present improvements, in lieu of con-
necting a series of interchangeable valve casings as herein before described, there is
used a continuous pipe or tube equivalent to the through communication afforded
by the said connected-lateral-branches of the valve casings, such continuous pipe
-or-tube-being-provided at suitable intervals with elbows or-branches at right angles
thereto and each of which elbows or branches acts as a valve casing or is fitted or
provided with a screw down or other tap or valve, so that the same effect as in the
modification heroin before firstly described is attained, namely, there is a continuous
through way in which the water or liquids of different temperatures or the different
liquids mix, and branches thereinto by which the said water or liquids is admitted,
and other branches therefrom by which the said water or liquids is allowed to escape
.to whero required each of the said taps or valves being under separate control.

WILLIAM DUNDAS SCOTT-MONCRIEFF, of Fulham, and WILLIAM DODDS, of
Westbourne Park, both in the County of Middlesex. "IMPROVEMENTS IN VALVE
APPARATUS FOR SUPPLYING BATHS AND OTHER APPARATUS WITH WATER, AND
AVAILABLE FOR ADMIXING OTHER LIQUIDS'
"
This Invention relates to certain improvements in valve apparatus for supplying
baths with hot and cold water or with water of any intermediate or required
temperature, and which improved valve apparatus is also applicable to other
apparatus in which differont liquids, or water or other liquids of different tempera-
tures, are required to be admixed. The Invention has, as principal objects, to
simplify the arrangement of valve apparatus necessary to supply hot and cold water,
or water of any required temperature, to plunge, spray, shower, douche, wave, sitz,
and other bath apparatus, or to admix different liquids, or water or other liquids of
different temperatures, in other apparatus, and to dispense with a considerable
portion of the usual plumbing work and skilled labor hitherto necessary, and to
reduce the number of working parts and render the whole arrangement easy to fit
up and to take apart.
According to a very advantageous modification of the present improvements, and
which is illustrated on the accompanying drawings in elevation and in part section
in Fig: 1, there is used a form of valve 1, known as a scrow down stool or pillar
valve. The casing 2, of each valve 1, is, according to these improvements, made
with two lateral branches or through ways 3, at right angles to a branch or through
way 4, which is at the rear of the casing and in alignment with the valve spindle 5.
One of the lateral branches is screw threaded externally, and the other is corre-
spondingly threaded internally, or these branches are otherwise conveniently and
interchangeably formed so that any number of them may be screwed or otherwise
suitably coupled or connected in through communication, one example of which is
illustrated in Fig; 1.
The improved arrangement of valve apparatus suitable for the purposes herein-
before indicated, consists of such a connected arrangement of interchangeable
valves and casings, with the terminal lateral branches suitably closed by screw
plugs 6, or by caps or other means. The rear branches of any two (or more) of
such a connected series of valve casings (but preferably of two adjacent valve
casings at one end of the series) form or serve as inlets for the hot and cold water
respectively, or for the different liquids, or for the liquids of different temperatures,
and thus, on one of the spindles of these valves being turned so as to open its valve,
the water of one temperature, or one of the different liquids can separately flow, or
by opening the two valvos, the water or different liquids can be admixed to or in
any desired temperature or proportion, and then freely flow into and through all
the said valve casings and their connecting lateral branches. The rear branchés
of the other valve casings serve as outlets which respectively communicate through
separate pipes to the plunge, spray, douche, shower, wave, sitz, or other bath
apparatus or to where else required. Thus upon turning or raising any one or all
of these other valves, the hot or cold water, or the admixed water or liquids, can be
discharged or allowed to escape to any or to all parts of the bath or other apparatus
at the same time.
There is an advantage in laying on the water which is at the greatest pressure
to the upper one of the two inlet valves, and in placing a drop valve 7, in a
seating 8, between the two inlet valves, as this prevents any circulation between

page_text: these parts when the outlets are all shut off, though the inlet valves should be left
open.
There may also be used, separately or in combination with the drop valve or its
equivalent, a small drip pipe 9, flowing into the bath or other apparatus from the
bottom of the lowest valve casing, to indicate that the inlet valves are open.
The screwed ends 10, of the inlets and outlets 4, may be made straight, or with
bends, and may be directly let into and soldered to the various pipes leading from
the supply and to the various parts of the bath apparatus.
In addition to the improved arrangement of valve apparatus being thus especially
serviceable for connection in a series, the separate sections are serviceable for
various analogous uses.
According to another modification of the present improvements, in lieu of
connecting a series of interchangeable valve casings as hereinbefore described, there
is used a continuous pipe or tube equivalent to the through communication afforded
by the said connected lateral branches of the valve casings, such continuous pipe
or tube being provided at suitable intervals with elbows or branches at right
angles thereto, and each of which olbows or branches acts as a valve casing or is
fitted or provided with a screw down or other valve, so that the same effect, as in
the modification herein before firstly described, is attained, namely, there is a
continuous through-way in which the water or liquids of different temperatures or
the different liquids can mix, or through which they can be separately passed, and
branches thereinto by which the said water or liquids is admitted, and other
branches therefrom by which the said water or liquids is allowed to escape to
whore required, each of the said taps or valves being under separate control.
Having thus particularly described and ascertained the nature and objects of our
said Invention, and in what manner the same is to be or may be performed or
carried into practical effect, I would observe in conclusion that what we consider to
be novel and original and therefore claim as constituting the Invention secured to
us by the hereinbefore in part recited Letters Patent, is :—
•
1. In valve apparatus for supplying baths and other apparatus with water of
different temperatures, and available for admixing other liquids, the combination
of a series of valve casings, each having a separate valve under independent control,
so as to form a continuous throughway, into and through which the different
liquids may be admitted separately, or in any required admixture, and from which
they may be led to where required, through the said independent valves: substan-
tially as herein before described.
2. The formation of such a through way with branchos for admitting and allowing
of the escape of the different liquids separately, or in any required admixture, by
means of a continuous length of pipe or tube provided at intervals with elbows or
branches acting as valve casings, and fitted with suitable valves under independent
control, substantially as hereinbefore described.
In Witness whereof, I, the said William Dundas Scott-Moncrieff, on behalf of
myself and the said William Dodds, have hereunto set my hand and seal,
this 23rd day of April, in the year of our Lord One thousand, eight
hundred and eighty three.
Witness.
