PROVISIONAL SPECIFICATION.
Improvements in the Method of Controlling the Supply of Steam
and Water or other Fluids to Injectors, Ejectors, and other
Appliances.
I GEORGE GLYDON of 27 Lordswood Road, Harborne, in the County of
Stafford Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to enable an unskilled person to perform the
action of regulating or controlling the supply of steam, water, or other fluids or
liquids to injectors, ejectors, and other apparatus in a more efficient manner than
hitherto.
I will describe my invention as applied to an ejector used for heating water (but
my invention is equally applicable to injectors, and other appliances requiring two
controlling valves. In this case, I use an outer casing, by preference a casting of
metal, having inlet passages for steam and water, cach controlled by valves in the
following manner : There are valve seats formed in the conducting passages for
the supply of steam and water respectively, arranged in such a manner with regard
to each other, that the actuating spindle when raising one valve from its seat,
simultaneously or otherwise as required raises the other valve, that is to say, both
valves can be made to open together, or one after the other, so as to give the
relative proportions of the steam and water supply.
Two nozzles of the usual internal construction are either formed in the body of
the casing or casting before mentioned, or are attached thereto by screw threads,
flanges or other means, one of which nozzles forms the delivery outlet for the hot
water.
Check valves may also be placed either in the body casing or casting, or in
connection therewith for the purpose of preventing the flow of steam through the
water inlet, or of water through the steam inlet.
Dated this 2nd day of November 1894.
COMPLETE SPECIFICATION.
Improvements in the Method of Controlling the Supply of Steam
and Water or other Fluids to Injectors, Ejectors, and other
Appliances.
I GEORGE GLYDON of 27 Lordswood Road, Harborne, in the County of
Stafford, Engineer, do hereby declare the nature of tbis invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of my invention is to enable an unskilled person to perform the
action of regulating or controlling the supply of steam, water, or other liquids or
fluids to injectors, ejectors, and other apparatus in a more efficient manner than
hitherto

page_text: I will describe my invention as applied to an ejector used for heating water (but
my invention is equally applicable to injectors and other apparatus requiring two
controlling valves). In this case I use an outer casing by preference a casting of
metal, having inlet passages for steam and water, each controlled by valves in the
following manner.
There are valve seats formed in the conducting passages for the supply of steam
and water respectively, arranged in such a manner with regard to each other, that
the actuating spindle when raising one valve from its seat, simultaneously or
otherwise as required, raises the other valve, that is to say, both valves can be
made to open together, or one after the other, so as to give the relative proportions
of the steam and water supply.
Two nozzles of the usual internal construction are either formed in the body of
the casing or casting before mentioned, or are attached thereto by screw threads,
flanges, or other means, one of which nozzles, forms the delivery outlet for the hot
water.
Check valves may also be placed either in the body casing or casting or in
connection therewith, for the purpose of preventing the How of steam through the
water inlet or of water through the steam inlet.
The accompanying drawings shew the general construction of the apparatus, and
the manner in which the object of my invention is attained.
Fig. 1 is a side elevation of the complete apparatus.
Fig. 2 is a plan of same with handwheel removed.
In Fig. 3 the apparatus is shewn with the spindle a screwed down and the water
valve band steam valve c both closed on to their seats. On turning the hand-
wheel d to raise the spindle a the following chain of actions will take place.-The
top of screw thread on the spindle a coming in contact with the underside of the
water valve b, and at the same time easing the pressure on the coiled spring i, raises
the water valve b from its seat, which with its packing p, spring i and washers, all
travel up, together with the spindle and handwheel, and allow cold water to pass
through the apparatus, and out at the spout or delivery outlet e. When the
screw spindle a has risen sufficiently high, for the collar a¹ thereon, to come in
contact with the underside of the gland c in steam valve c and overcoming the
pressure of the steam and coiled spring f, the steam valve will also be lifted from
its seat, thus allowing steam to begin to mix with the inflowing cold water, by
means of the injector nozzles g & h. By raising the spindle still further, the steam
and water valves are carried up with it, and as the ports in the cylindrical
casing of the steam valve c, have a regularly increasing area, it follows, that the
water delivered, will steadily rise in temperature as the valve is raised.
When it is desired to open both valves together, this result is attained by
attaching the collar a higher up the spindle so that the top of thread, and the
collar on the spindle, come in contact with the water and steam valves respectively
at the same time.
On lowering the spindle a it will be seen that the movements are reversed; that
is to say, the steam valve c is first closed by means of the coiled spring and the
pressure of the steam; then the water valve 6 is brought down to its seat, by the
pressure of the coiled spring which is under permanent pressure from the nut on
top of spindle; finally the complete screwing down of the spindle a forces the
steam valve c tightly on to its seat; at the same time compressing still further the
spring which forces the water valve b on to its seat.
These successive actions of the water valve band steam valve c in opening and
closing by one spindle a in conjunction with the action of the springs f& i to each
valve, form an important feature in my invention,

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an apparatus for heating water by steam, a water valve and steam valve
moved and controlled in opening and closing, by one screw spindle, and two
springs, in combination with the water and steam inlets, the combining nozzles, and
the outlet, as described and illustrated.
2. In an apparatus for heating water by steam :-a steam valve, having ports
in a cylindrical casing, in combination with a water valve, both moved and
controlled in opening and closing, by one screw spindle and two springs, as
described and illustrated.
3. The water heating apparatus shewn in Figs. 1. 2. 3 & 4.
