LEWIS MARSHALL, 34, Elmfield Terrace, Savile Park, Halifax, Manager &
Director, and SAM NAYLOR, 32, Elmfield Terrace, Savile Park, Halifax, Manager
& Director, do hereby declare the nature of this invention to be as follows:-
This invention is an appliance or valve constructed of metal, with a body hav-
ing a central passage and one or more suitable openings into same for the inlet
of steam on one side of body & on the other with one or more suitable openings
for the inlet of cold water.
Into the said central passage of body is fitted a spindle (or plug) having a
rectangular passage communicating with the opening or openings in body pro-
vided for the inlet of steam, and on the outer or circumferential side of said
spindle (or plug) are one or more flutes (or hollows) communicating with the
opening or openings in the body provided for the inlet of cold water. These
openings for the inlet of steam & cold water communicate seperately & are so
arranged with the flutes (or hollows) in the said spindle (or plug) that by turn-
ing same with a handle or suitable devise into a certain position, steam & cold
water are admitted into the central passage of body simultaneously & the cold
water becoming instantly heated passes out of a suitable opening in the body
of valve. By partially turning the said spindle (or plug) absolutely cold water
can be obtained.

A New and Improved Appliance for Heating Water by Steam.
We, LEWIS MARSHALL, of 34, Elmfield Terrace, Savile Park, Halifax, in the
County of York, Manager and Director, and SAM NAYLOR, of 32, Elmfield Terrace,
aforesaid, Manager and Director, 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:-
-
This invention relates to improvements in appliances designed for heating
water by means of steam in such a manner that hot, warm, or cold water can be
obtained at will and drawn from one and the same valve. The invention con-
sists of an appliance or valve having a central passage through its body and one
or more openings into same for the inlet of steam and said central passage com-
DQ71

page_text: municates with a cold water supply and both the steam and cold water supply
can be regulated and controlled by the one plug of the valve so that the water
drawn through the valve can be more or less heated according as the quantity
of steam in proportion to the quantity of cold water is reduced or increased and
by turning the lever or handle of the valve to different positions hot, warm, or
cold water can be drawn from the supply valve.
Such being the nature and object of our said invention the following is a com-
plete description of same reference being had to the accompanying drawings,
in which:
Fig. 1 is a sectional side elevation of the improved valve or appliance for pur-
pose aforesaid.
Fig. 2 is a sectional plan view on line A, B, of Fig. 1.
Fig. 3 is a sectional plan view on line C, D, of Fig. 1.
Fig. 4 is a view in elevation of the plug of the valve.
Fig. 5 is a sectional plan view on line E, F, of Fig. 4.
According to this invention the appliance or valve comprises the body or
shell 1 and a plug 2 the upper part 3 of which constitutes the valve spindle. The
plug 2 is hollow or has a central passage way 4 communicating by means of the
port or opening 5 with the steam inlet 6. On the periphery of the plug 2 are
one or more, preferably two, flutes or recesses 7, 7 extending so far up the plug 2
as to be lineable with and capable of being brought by turning the plug 2 oppo-
site the cold water inlet 8. The flutes or recesses 7, 7 communicate with the
chamber 9 in the body or shell 1 and by the opening 10 with the outlet to the
valve so that the steam passing through the passage way 4 and the cold water
through the flutes 7, 7, and opening 10 mingle at the point of contact 11 in the
valve. The appliance is connected with a steam supply and with a cold water
supply and the discharge nozzle 12 may be open or connected with a pipe leading
to any desired point. At 13 is a projection or stop in the plug 2 received in the
recess 14 in the shell or body 1 of the valve and the amount of movement of the
plug 2 is limited by such pin 13 coming into contact with the ends of the recess 14
about half a revolution or full turn of the plug 2 only being allowed.
The action is as follows:-The valve is closed when the plug.2 is turned so
that its solid or blank parts are opposite the steam inlet 6 and the water inlet 8
and by giving a partial turn, about a quarter, the flutes or recesses 7, 7 are
brought opposite the cold water ports 8,8* which branch to each side of the
plug 2 from the inlet 8 and cold water is allowed to pass through the valve. If
however the plug 2 is turned a little further the port or opening 5 is brought
opposite to the steam inlet 6 and steam is admitted and the steam and water
mingle at the point of contact 11 and steam heated water issues from the nozzle 12.
The degree of heat of the water can be regulated by turning the plug 2 so opening
the steam and water supplies more or less so that hot, cold, or warm water can
be drawn. It will be obvious that the water may be supplied through the inlet 6
and the steam fed through the inlet 8 if desired.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
(1) The general construction, arrangement, and combination of parts constitu-
ting the improved valve or appliance as and for the purpose herein described
and substantially as illustrated by Fig. 1 of the annexed drawings.
(2) The body or shell 1 having inlets 6-8 the plug 2 with a central passage 4
and flute or flutes 7 and the outlet way or nozzle 12 all in combination as and
for the purpose herein described.
(3) A valve or appliance comprising an inlet for steam and an inlet for water
controlled by one plug and handle and both inlets discharging through one outlet
for the purpose herein described.
(4) The body or shell 1 having inlets 6-8 and passage ways such as 4 and 7

page_text: through the central portion so that steam and water admitted through the inlets
mingles before or at the point of contact through the nozzle 12 for the purpose
herein described.
