of 6, Lord Street, Liverpool, in the County of Lancaster, and 323, High
Holborn, in the County of Middlesex, Civil Engineer. "IMPROVEMENTS IN AND

Gentleman.
The object of this Invention is to provide a faucet having but one handle which
is adapted to be connected with both hot and cold water pipes, by which water
may be drawn from either the hot or cold water pipe separately or from both
pipes simultaneously, as desired, and also by which the flow of water may be
graduated from hot to cold or from cold to hot to any temperature desired. A
further object of this Invention is to provide a device by which the operator may
definitely know where to adjust the handle for either hot, cold, or temperate water.
as well as the point of adjustment for closing the faucet.
This Invention consists of a valve chamber, a hot water inlet, which is provided
with a stopper, a cold water inlet, which is also provided with a stopper; these
[Price 61

page_text: stoppers are respectively provided with valve rods. Ways are formed upon the
respective sides of the chamber for the reception of slides, which slides are moved
upward and downward by a cam, whereby the respective hot and cold water
passages are opened and closed; this cam is rigidly secured to a stem and is moved
with it as the bandle is moved. An index plate upon which the words "hot,"
" cold," medium," and "stop," are written, is fixed behind the handle, thus
indicating the proper places of adjusting the handle to produce the result thus
indicated. The stoppers are formed of rubber or other elastic substances in the
ordinary manner. The valve case or chamber may be cast in a single piece, and
the cover or index plate secured thereto by a screw joint.
The cam that operates the hot and cold water valve is so formed that a portion
of it forms a true horizontal plane which extends at right angles to the vertical
stem to which it is attached.
The other part inclines downward forming an obtuse angle from the highest to
the lowest point in the cam.
About one third of the area of cam, consisting of that latter part, is formed
upon different inclined planes; the hot and cold water valves are both located upon
one side of the centre, whereby both valve slides may simultaneously rest upon
the horizontal portion of said cam, and both stoppers be thereby retained in a
closed position at the same time. This Invention consists further in providing the
respective slides with anti-friction rollers between which the cam moves as the
handle is turned; also in providing the outlet spout and another outlet tube
respectively with stopcocks, and by which stopcocks the course of water may be
readily changed. When the stop cock on one tube is closed the water will flow
through the other tube, and vice versa.
The words "hot" and "cold" are located one side of the centre conforming to
the position of the hot and cold water valves.
The faucet is operated as follows:-When the handle is moved to the word
"hot" the slide in connection with the hot water valve is moved downward by the
cam, whereby the hot water valve is opened, while the slide in connection with
the cold water valve is simultaneously acted upon by the opposite side of the cam
and moved in the opposite direction, whereby the cold water valve is closed.
When the handle is moved from the word "hot" to "stop," the upward incline of
cam acting upon the slide connected to the hot water valve draws the stopper
upward-and-closes the hot water valve, while the horizontal portion of said cam
moves through the slide connected to the cold water valve-without-changing-its
level, while it retains the stopper in its closed position, thus both passages are
closed and the flow of water stopped. When the handle is moved on from the
word "stop" to the word "cold" the horizontal portion of the cam moves through
the recess in slide connected with the hot water valve without changing its position
and while it retains the stopper unmoved in the closed position, the angular
portion of said cam acts upon slide connected with the cold water valve, forcing
it downward, whereby the cold water valve or stopper is opened. When the
handle is moved on from "cold" to "medium the respective slides are acted upon
by the inclined portion of the cam, and are both thereby simultaneously thrown
half way open, whereby the hot and cold water is mingled together in equal
proportions. It is obvious that by moving the handle from the word "medium
toward the word "hot" the hot water valve will be thrown more widely open
while the cold water valve will be partially closed, whereby an excess of hot water
is caused to flow; also that when the handle is inversely moved from the word
"medium" toward the word "cold" the opposite result is produced.

Thus it is obvious that the flow of water from the faucet may be readily
graduated from cold to hot or from hot to cold to any temperature desired.

WILLIAM PHILLIPS THOMPSON, of the Agency for Foreign Patent Solicitors,
of 6, Lord Street, Liverpool, in the County of Lancaster, and 323, High
Holborn, in the County of Middlesex, Civil Engineer. " IMPROVEMENTS IN AND
RELATING TO FAUCETS OR TAPS, USEFUL WHERE TWO VARIETIES OF LIQUID,
SUCH AS HOT AND COLD WATER, HAVE TO BE DRAWN IN VARYING PROPORTIONS."
A communication from abroad by Charles Whittaker, of the City of Chicago,

.
The following is the description of the Invention as communicated to me :-
The object of this Invention is to provide a faucet having but one handle, which
is adapted to be connected with both hot and cold water pipes, by which water
may be drawn from either the hot or cold water pipe separately, or from both
pipes simultaneously as desired, and also by which the flow of water may be
graduated from hot to cold or from cold to hot to any temperature desired. A
further object of this Invention is to provide a device by which the operator may
definitely know where to adjust the handle for either hot, cold, or temperate water,
as well as the point of adjustment for closing the faucet.
This Invention is further explained by reference to the accompanying Drawings,
in which Figure 1 represents a vertical section drawn on line X, X, of Fig. 3;
Fig. 2 is a side view of the cam; Fig. 3 is a horizontal section; Fig. 4 is a top
view; Fig. 5 is a side view.
A is the valve chamber; B is the hot water inlet which is provided with a
stopper C; D, is the cold water inlet, which is also provided with a stopper E.
These stoppers C and E are respectively provided with valve rods F and G.
Ways H, H, are formed upon the respective sides of the chamber for the reception of
the slides I, I. The slides I, I', are moved upward and downward by cam J, whereby
the respective hot and cold water passages are opened and closed. The cam J is
rigidly secured to the stem M, and is moved with it as the handle N is moved. O is
the index plate upon which the words "hot," "cold," "medium," and "stop" are
written, thus indicating the proper places of adjusting the handle to produce the
result thus indicated. The stoppers are formed of rubber or other elastic substances
in the ordinary manner. The case or chamber A may be cast in a single piece,
and the cover or index plate O secured thereto by a screw joint, as shown.
That portion of the cam J between 1 and 2 forms a true horizontal plane which
extends at right angles to the vertical stem M. The part between 2 and 3 and
1 and 3 respectively inclines downward, forming an obtuse angle from the highest
to the lowest point.in the cam. About one third of the area of cam J, consisting
of that part between 1 and 3 and 2 and 3 is formed upon different inclined planes,
as shown by dotted lines in Fig. 2; the hot and cold water valves are both located
upon one side of the center, as seen in Figs. 3 and 4, whereby both valve slides
may simultaneously rest upon the horizontal portion of said cam, and both stoppers
be thereby retained in a closed position at the same time. This Invention consists
further in providing the respective slides I, I, with anti friction rollers b; b, b, b,
between which the cam j moves as the handle is turned.
Also in providing the spout P and the tube R respectively with stopcocks S
and T, by which stop cocks the course of water may be readily changed.

page_text: When the stop cock S is closed, the water will flow through tube R; when
stop cock T is closed and the stopcock S is opened, the water will take the ordinary
course through the spout.
The words "hot" and "cold" are located one side of the center, conforming to
the position of the hot and cold water valves.
The faucet is operated as follows:-
When the handle N is moved to the word "hot," the slide I is moved downward
by the cam J, whereby the hot water valve C is opened, while the slide I' is
simultaneously acted upon by the opposite side of the cam and moved in the
opposite direction, whereby the cold water valve E is closed. When the handle is
moved from the word "hot" to "stop," the upward incline of cam J, acting upon
the slide I, draws the stopper C upward and closes the hot water valve, while the
horizontal portion of said cam moves through the slide I¹ without changing its
level, while it retains the stopper in its closed position; thus both passages are
closed, and the flow of water stopped. When the handle is moved on from the
word "stop" to the word "cold," the horizontal portion of cam J between 1 and 2
moves through the recess in slide I without changing its position, and while it
retains the stopper C unmoved in the closed position the angular portion of said
cam acts upon slide 1, forcing it downwards, whereby the cold water valve or
stopper E is opened. When the handle is moved on from " cold." to "medium,"
the respective slides are acted upon by the inclined portion of the cam and are both
thereby simultaneously thrown half way open, whereby the hot and cold water is
mingled together in equal proportions. It is obvious that by moving the handle
from the word "medium" toward the word "hot," the hot water valve will be
thrown more widely open, while the cold water valve will be partially closed,
whereby an excess of hot water is caused to flow also that when the handle is
inversely moved from the word "medium" toward the word "cold" the opposite
result is produced. Thus it is obvious that the flow of water from the faucet may
be readily graduated from cold to hot, or from hot to cold to any temperature
desired.
Having now described the Invention as communicated to me, what I claim under
the Letters Patent is,-
1st. In hot and cold graduating faucet a single chamber provided with both hot
and cold water inlets and one or more outlets, which inlets are respectively provided
with-stoppers-connected_with_and_adapted to be operated by a single handle,

2nd. In a hot and cold water graduating faucet an index plate provided with
words or signs to indicate the proper places of adjustment of the handle for
stopping the flow of water or for producing a hot, cold, or temperate water, sub-
stantially as and for the purpose set forth.
3rd. In a hot and cold water graduating faucet, the cam J forming three distinct
planes, one horizontal and two inclined conversely, arranged as connected with
the handle and hot and cold water valves or stoppers, said cam being adapted to
move said stoppers both simultaneously and alternately in opposite directions, or
retain them both at the same time in a closed position, as set forth.
4th. In a hot and cold water graduating faucet the combination of the case A,
upwardly extending tube R, spout P, stop cocks S and T, said stop cocks being
adapted to change the course of the stream from a downward to an upward
direction, or inversely in an opposite direction as desired, substantially as and for
the purpose set forth.
5th. In faucets the combination of the slides I, I', antifriction rollers b, b, b, b,
and cam J, substantially as set forth.
6th. In a hot and cold water graduating faucet the combination of index plate O
