Improved Inlet and Shower or Spray Fitting for Baths, Lavatories,
and the like.
We, JAMES MILNE, Milton House Works, Abbeyhill, Edinburgh, Engineer, and
HARRY CHESHIRE, Milton House Works, Abbeyhill, Edinburgh, Brass Works
Manager, do hereby declare the nature of this invention to be as follows:-
Our invention consists of an outer chamber to which hot and cold water res-
pectively are admitted by two inlets on opposite sides of the chamber. The
chamber is fitted with a hollow circular plug, the interior of which forms. a
mixing box and has two inlet openings on opposite sides. The under part of
this plug has à groove or recess in an upward direction, extending from one
side of the plug to the other at right angles to the line of the two inlet openings
already described. It has also a further opening forming an outlet from the
interior or mixing box and situated immediately above one end of the groove.
or recess. These openings and the groove or recess are so arranged that when
the plug is placed in position within the outer chamber with its two inlet open-
ings in line with the two inlets of the outer chamber, the inlet opening of the
mixing box comes opposite a third opening formed in the side of the outer cham-
ber midway between the two inlets thereof and serving as an outlet thereto.
This latter outlet is placed sufficiently high that, while it is in direct communi-
cation with the outlet of the mixing box, there is no connection whatever between
it and the groove or recess immediately below. In the bottom of the outer
chamber is a fourth opening forming a downward outlet from outer chamber,
and leading towards the bath.
With the plug in position within the outer chamber and the two inlets of
the mixing box placed at right angles to the line of the two inlets of outer cham-
ber, the groove or recess falls into line with the two latter openings in such a
way that when the cold and hot water is admitted from opposite sides by these
two inlets of outer chamber, it passes by way of the recess or groove and thence
downwards through the downward outlet above described into the bath. While
the plug is in this position no water can gain access to the interior of the mix-
ing box, as all three openings into same are in contact with solid parts of the
wall of outer chamber. By revolving the plug a quarter of a circle the two
inlets of mixing box come opposite the corresponding inlets of outer chamber,
while at the same time the outlet opening of the former comes opposite the
outlet of the latter. By this means the hot and cold water coming from oppo-
site sides enters the mixing box by its two opposite inlets, and passing through
its outlet and the outlet of outer chamber, is led by a convenient pipe to the
shower or spray.
The circular travel of the plug is regulated by a suitable stop, and the plug
is kept in position by any ordinary valve cover, and is rotated by a -knob or
handle suitably attached to it.
Alternatively the outer chamber may have a further outlet opening in its side
opposite to the outlet above described, in which case one of these outlet openings

page_text: would be connected with the spray and the other with the shower arrangement,
while the plug would be made free to turn completely round so that the outlet
of mixing box could be brought opposite either of these last mentioned two
outlets of outer chamber and the water admitted to spray or shower, as-desired.
Alternatively the foregoing arrangement may be inverted, in which case the
various connections would be where necessary reversed, the downward outlet of
outer chamber becoming an upward outlet and being connected to the shower,
while one of the side outlets inight be connected to the bath and the other to
the spray or otherwise, according to circumstances.

Improved Inlet and Shower or Spray Fitting for Baths, Lavatories,
and the like.
We, JAMES MILNE, Milton House Works, Edinburgh, Engineer, and HARRY
CHESHIRE, Milton House Works, Edinburgh, Brass Works' Manager, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
The fitting which forms the subject of our invention has an outer chamber
to which hot and cold water respectively are admitted by two inlets on oppo-
site sides of the chamber. Into this outer chamber is fitted a hollow circular
plug, the. interior of which forms a mixing box and has two inlet openings on
opposite sides. The under part of this plug has a groove or recess in an upward
direction, extending from one side of the plug to the other at right angles to
the line of the two inlet openings already described. It has also a further open-
ing forming an outlet from the interior or mixing box and situated immediately
above one end of the groove or recess. These openings and the groove or recess
are so arranged, that when the plug is placed in position within the outer cham-.
ber with its two inlet openings in line with the two inlets of the outer chamber,
the inlet opening of the mixing box comes opposite a third opening formed in
the side of the outer chamber midway between the two inlets thereof, and serv-
ing as an outlet thereto. This latter outlet is placed sufficiently high that, while
it is in direct communication with the outlet of the mixing box, there is no con-
nection whatever between it and the groove or recess immediately below. In
the bottom of the outer chamber is a fourth opening forming a downward outlet
from outer chamber.
With the plug in position within the outer chamber and the two inlets of
the mixing box placed at right angles to the line of the two inlets of outer cham-
ber, the groove or recess falls into line with the two latter openings in such a
way that when the cold and hot water is admitted from opposite sides by these
two inlets of outer chamber, it passes by way of the recess or groove and thence
downwards through the downward outlet above described, from which it
otherwise
be led to the bath, or
as required. While the plug
is in this position no water can gain access to the interior of the mix-
ing box, as all three openings into same are in contact with solid parts of the
wall of outer chamber. By revolving the plug a quarter of a circle the two
inlets of mixing box come opposite the corresponding inlets of outer chamber,
while at the same time the outlet opening of the former comes opposite the outlet
can

page_text: of the latter. By this means the hot and cold water supplies coming from oppo-
site sides enter the mixing box by its two opposite inlets, and after being mixed
within same and passing through its outlet to the outlet of outer chamber, the
water is led by a convenient pipe to the shower, spray, or other desired point.
The circular travel of the plug is regulated by a suitable stop, and the plug
is kept in position by any ordinary valve cover and is rotated by a “knob or
handle suitably attached to it.
Alternatively the outer chamber may have a further outlet opening in its
side opposite to the outlet above described, in which case one of these outlet
openings might be connected with the spray and the other with the shower
arrangement, or otherwise as required, while the plug would be made free to
turn completely round so that the outlet of mixing box could be brought oppo-
site either of these last mentioned two outlets of outer chamber and the water
admitted to either of these outlets as desired. This alternative outlet, like that
opposite to which it is suggested to place it, would also be placed sufficiently
high that while it would be in direct communication with the outlet of the mix-
ing box, there would be no communication whatever between it and the groove
or recess immediately below.
Alternatively the foregoing arrangement may be inverted, in which case the
various connections would be where necessary reversed.
For more particular description of our invention, we now refer to the accom-
panying drawings, in which A is the outer chamber and B the hollow plug
fitting into same. C and D are the inlet openings of the plug B, and E is the
groove or recess on the under part of same. F is the outlet opening from the
interior of the plug B, and G and H are the two inlet openings of the outer
chamber A. J is the third opening in the outer chamber A, and is so placed
midway between G and H that when G and I are in line with C and D, the inlet
opening F comes opposite J. The outlet J, as will be seen from Figure 5, is
placed so high that at no position of the plug B is there any connection between
the groove E and said opening J. K is the downward outlet from the outer
chamber A. L shews the alternative fourth outlet opening in the outer chamber A.
Figure 1 shews the outer chamber A in section at M N on plan, with the
plug B, also in section, in position within the outer chamber A, and with the
openings C and D opposite the openings G and H. In this position of the
plug B, the groove E is closed at both ends by the wall of the outer chamber A,
and there is therefore no outlet through K. Figure 4 shews the same but with
the plug B revolved a quarter of a circle. In this position of the plug B, the
openings C, D and F in same are closed by contact with the walls of the outer
chamber A, while the inlet openings G and H of the outer chamber A are in
line with the groove E, which latter is open to the outlet K. Figure 5 shews
the outer chamber in section at OP on plan, with the plug turned a further
quarter of a circle in the same direction, so that the outlet F is opposite the
outlet J, the inlets C and D being opposite the inlets G and H of the outer
chamber A, while again the groove E and the outlet K are closed. Figure 6
shews the same but with the plug B revolved so that its opening F is opposite
the alternative further opening L in outer chamber A. Figures 2 and 3 are
elevations of the plug B, shewing the groove E and the opening C respectively,
and also the opening F in front and side elevation respectively.
Having now particularly described and ascertained the nature of our said in-
vention, and the manner in which same is to be performed, we declare that what.
we claim is :-
(1) In fittings for baths, lavatories and the like where hot and cold water
may be used together, the use of a hollow plug working within an outer chamber,
its interior forming a mixing box furnished with two inlets, which (when the
plug has been suitably revolved) communicate with the two corresponding inlets
of outer chamber, and also furnished with one or more outlets arranged to com-

page_text: municate (when the plug has been suitably revolved) with one or more corres-
ponding outlets in outer chamber, and said plug having on its under side a
groove or recess arranged to communicate with the two inlets of outer chamber
(when plug has been suitably revolved) and simultaneously to communicate with
remaining outlet of outer chamber; all. as hereinbefore described and illustrated
in the annexed drawings.
-
(2) Our hereinabove described apparatus forming a fitting for baths, lavatories.
and the like, admitting of use for two, or if desired, three distinct deliveries of
mixed hot and cold water, all obtained by the manipulation of one and the same
lever handle or tap; all substantially as and for the purposes herein before
described, and as illustrated in the accompanying drawings.
Dated this Twenty-third day of January, One thousand nine hundred.
