PROVISIONAL SPECIFICATION.
Improvements in Injectors or Apparatus for Feeding Steam Boilers
or Generators and for other Purposes, and in Arrangements in
Connection with the same.
We, EDWARD DAVIES of Plas Dinam, Llandinam, in the County of Montgomery,
Engineer, and JAMES METCALFE of 28 North Parade, Aberystwith, in the County of
Cardigan, Engineer, do hereby declare the nature of the said invention, to be as
follows:-
Firstly Our improvements relate to automatic compound exhaust and supple-
mentary live steain Injectors and are made upon those described in the specifications
of Letters Patent granted to us No. 5730 and 5731 A.D. 1887, and our invention
consists in forming the combining nozzles of the supplementary injectors with an
hinged flap similar to that used in the Exhaust steam Injector, and we use this
hinged flap combining cone in the live steam Injectors with either the steam central
or annular.
Our invention also consists in combining in compound Exhaust and supplementary
live steam injectors the hinged flap combining and receiving and discharging cones
or nozzles connected together to screw in and out at the end of the casing of the
live steam injector, same as in the simple Exhaust Steam Injector.
We combine our present improvements with a starting valve either loaded by a
spring or a diaphragm, acted upon by the pressure of the fluid discharged from the
supplementary Injector as explained in our aforesaid Complete Specifications.
We also combine our present improvements with an exhaust steam Injector, either.
with the axis of the supplementary Injector in a line with or at a right to the axis
of the Exhaust Injector.
We also combine our present improvements in the supplementary live steam
Injector with the Exhaust steam Injector having a live steam nozzle in the exhaust
steam nozzle of the Exhaust Injector.
In Exhaust and supplementary live steam injectors we also combine and arrange
tho Exhaust steam nozzle so as to be adjustable by an excentric or other means to
regulate the water supply.
Our present improvements also consist in combining the flap nozzle with the
supplementary Injector, when the compound Exhaust and live steam Injectors are
arranged as illustrated by fig. 5 of our said Specification No. 5731-1887.
Our present invention also relates to improvements upon that modification of
compound Exhaust and supplementary live steam Injectors illustrated by figs. 8 and 9
of our said Complete Specification No. 5731-1887-and according to our present
improvements the live steam to the supplementary injector may be either central or
annular. The combining cone for live steam and fluid from the Exhaust Injector is
formed in two parts one (the first part) is fixed in the casing of the injector and the
other part is arranged to slide to and from the fixed part of the combining nozzle.
When the two parts of the nozzle are in contact the combining cone is continuous
as when the jet has been established, and when the two parts of the nozzle are apart
as when the jet is interrupted, there is a free outlet for the fluid through an overflow
outlet closed by a valve loaded by a weight spring or diaphragm or piston acted upon
by the pressure of the fluid delivered.
The movable part of the combining cone or nozzle slides or may slide in a part
from the end of the discharging cone or nozzle.
Secondly. Our invention relates to live steam Injectors actuated by two or more
jets of live steam and consists in applying for this purpose the improvements above.
described under the first head of our invention, the first live steam injector taking the,

page_text: 66
place of the exhaust steam Injector being formed either with a flap" combining
cone or nozzle or with ordinary combining cones or nozzles.
Thirdly. In the case of compound automatic Exhaust and supplementary live
steam Injectors our invention consists in arranging the cock or valve controlling the
supply of live steam and that for controlling the supply of water to the Injectors so
as to be in connection by rods, levers or other equivalents, with the regulator or
handle controlling the supply of steam to the Engine, so that when the steam is shut
off from, or turned on to, the Engine or Engines the steam and water will also be
shut off from or turned on to the compound Exhaust and supplementary Injector or
Injectors.
Instead of turning the water on and off by direct connection with the regulator,
the steam when turned on by the regulator to the live steam injector is or may be
arranged to operate upon a piston or diaphragm to actuate the water supply cock or
valvo and instead of actuating the live steam cock or valve or both the cocks or
valves for live steam and water supply directly from the regulator or as above
explained they are or may be actuated by a piston or pistons, diaphragm or diaphragms
operated by steam, turned on or off by the regulator when turning on or off the
supply of steam to the main cylinders of the Engine.
Thus the waste of steam and water will be prevented as when the Exhaust Injector
ceases to work in consequence of the stoppage of the Engine or Engines supplying
it, the live steam will be cut off from the compound automatic Exhaust and live
steam Injector at the same time, and will be turned on again as soon as the supply of
Exhaust steam commences to be discharged from the Engine or Engines.
"
Another mode of carrying out this part of our invention for preventing waste of
steam or water, is to connect the "regulator of the Engine with a cock or valve so
that when steam is turned off from the Engine (which thus stops the discharge of
Exhaust steam to the Exhaust Injector) the cock or valve will be opened to turn on
a sufficient supply of live steam to the Exhaust injector to work it, which supply,
will be turned off when steam is turned on to the Engine by the "
"and
regulator
thus the compound Exhaust and supplementary live steam injector is kept working
by supplying live steam to the exhaust injector when there is no discharge of exhaust
steam from the Engine.
Or when steam is turned on to the Engine by the "regulator" it is or may be
made to act upon a piston or diaphragm so as to shut a cock or valve supplying live
steam to the Exhaust injector, when steam is turned on by the "regulator" to the
Engine and when steam is turned off from the Engine a spring or weight will act
upon the piston or diaphragm or its connections to turn on live steam to the Exhaust
injector.
The two systems of action hereinbefore described may be combined so that either
one or the other may be readily brought into operation.

COMPLETE SPECIFICATION.
Improvements in Injectors or Apparatus for Feeding Steam Boilers
or Generators and for other Purposes, and in Arrangements in
Connection with the same.
We, EDWARD DAVIES, of Plas Dinam, Llandinam, in the County of Montgomery,
Engineer, and JAMES METCALFE, of 28 North Parade, Aberystwith, in the County of
Cardigan, Engineer, 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 :-
Firstly. Our improvements relate to automatic compound exhaust and supple-
mentary live steam Injectors, and are made upon those described in the specifications
of Letters Patent granted to us No. 5730 and 5731 A.D. 1887, and our invention

page_text: consists in forming the combining nozzles of the supplementary injectors with an
hinged flap, similar to that used in the Exhaust steam Injector, and we use the hinged
flap combining cone in the live steam Injectors, with either the steam central or
annular.
Our invention also consists in combining, in compound Exhaust and supplementary
live steam Injectors the hinged flap combining and receiving and discharging cones
or nozzles connected together to screw in and out at the end of the casing of the
live steam Injector same as in the simple Exhaust steam Injector.
We combine our present improvements with a starting valve either loaded by a
spring or a diaphragm acted upon by the pressure of the fluid discharged from the
supplementary Injector as explained in our aforesaid Complete specifications.
We also combine our present improvements with an Exhaust steam Injector either
with the axis of the supplementary Injector in a line with, or at a right angle to the
axis of the Exhaust Injector.
We also combine our present improvements in the supplementary live steam
Injector with the Exhaust steam Injector having a live steain nozzle in the exhaust
steam nozzle of the Exhaust Injector.
In Exhaust and supplementary live steam Injectors, we also combine and arrange
the Exhaust steam nozzle so as to be adjustable by an excentric or other means to
regulate the water supply.
Our present improvements also consist in combining the flap nozzle with the
supplementary Injector, when the compound Exhaust, and live steam Injectors are
arranged as illustrated by fig. 5, of our said specification No. 5731-1887.
Our present invention also relates to improvements upon that modification of
compound Exhaust and supplementary live steam Injectors illustrated by figs. 8 and 9
of our said complete specification No. 5731-1887 and according to our present
improvements the live steam to the supplementary Injector may be either central
or annular. The combining cono for live steam and fluid from the Exhaust Injector
is formed in two parts, one [the first part] is fixed in the casing of the Injector, and
the other part is arranged to slide to and from the fixed part of the combining
nozzle.
When the two parts of the nozzle are in contact, the combining cone is continuous,
as when the jet has been established, and when the two parts of the nozzle are apart
as when the jet is interrupted there is a freo outlet for the fluid through an overflow
outlet closed by a valve loaded by a weight, spring or diaphragm or piston acted
upon by the pressure of the fluid delivered.
The movable part of the combining cone or nozzle slides or may slide in a part
from the end of the discharging cone or nozzle.
Secondly. Our invention relates to live steam Injectors actuated by two or more
jets of live steam, and consists in applying for this purpose, the improvements above
described under the first head of our invention, the first live steam Injector taking
the place of the Exhaust steam Injector being formed either with a "flap" combining
cone or nozzle, or with ordinary combining cones or nozzles.
Thirdly. In the case of compound automatic Exbaust and supplementary live
steam Injectors, our invention consists in arranging the cock or valve controlling
the supply of live steam, and that for controlling the supply of water to the Injectors
so as to be in connection by rods, levers, or other equivalents with the regulator or
handle controlling the supply of steam to the Engine so that when the steam is shut
off from or turned on to the Engine or Engines the steam and water will also be
shut off from or turned on to the compound exhaust and supplementary Injector or
Injectors.
Instead of turning the water on and off by direct connection with the regulator
the steam when turned on by the regulator to the live steam Injector is or may be
arranged to operate upon a piston or diaphragm to actuate the water supply cock
or valve, and instead of actuating the live steam cock or valve, or both the cocks or
valves for live steam and water supply directly from the regulator or as above explained
they are or may be actuated by a piston or pistons diaphragm or diaphragms,

page_text: operated by steam turned on and off by the regulator when turning on or off the
supply of steam to the main cylinders of the Engine.
Thus the waste of steam and water will be prevented, as when the Exhaust Injector
ceases to work in consequence of the stoppage of the Engine or Engines supplying
it, the live steam will be cut off from the Compound Automatic Exhaust and live
steam Injector, at the same time, and will be turned on again as soon as the supply of
Exhaust steam commences to be discharged from the Engine or Engines. Another
mode of carrying out this part of our invention for preventing waste of steam or
water, is to connect the regulator of the Engine with a cock or valve so that when
steam is turned off from the Engine [which thus stops the discharge of Exhaust
steam to the Exhaust Injector] the cock or valve will be opened to turn on a
sufficient supply of live steam to the Exhaust Injector to work it, which supply will
be turned off, when steam is turned on to the Engine by the regulator and thus the
Compound Exhaust and supplementary live steam Injector is kept working by
supplying live steam to the exhaust Injector when there is no discharge of exhaust
steam from the Engine.
Or when steam is turned on to the Engine by the regulator it is or may be made
to act upon a piston or diaphragm so as to shut a cock or valve supplying live steam
to the Exhaust Injector when steam is turned on by the "regulator to the Engine,
and when steam is turned off from the Engine a spring or weight will act upon the
piston or diaphragm or its connections to turn on live steam to the Exhaust Injector.
The two systems of action hereinbefore described may be combined so that either
one or the other may be readily brought into operation.
Fig. 1 is a longitudinal section of our improved combined Injectors and fig. 2 is
an outside view partly in section of a modified arrangement of the compound
Injector shown by fig. 1 according to the first part of our invention.
The Injectors illustrated, combine similar improvements to those described in the
specification herein before mentioned, except that a "hinged flap" combining nozzle
is used for the supplementary live steam Injector, and that the parts are constructed
and combined together in an improved manner.
a, is the outer casing of the exhaust steam part of the Injector in the upper part of
which, a barrel or lining 6, is inserted, for the exhaust steam nozzle b, to slide in,
the exterior of which has two grooves in it to retain packing material.
On the side of the casing a, there is a stuffing box for a spindle 2, which has an
excentric pin upon its inner end that fits a cross slot in the side of the exhaust steam
nozzle b, as shown.
There is an indexed hand wheel 63, on the outer end of the spindle 62, and a stud b*,
is secured in the side of the casing as a pointer to the index on the hand wheel by
which the annular space for water is adjusted.
a', is the branch for water.
The hinged flap combining nozzle c, and the receiving and discharging nozzle d,
are constructed and connected and arranged in the casing a, in the same manner,
[which is well known] as for the simple Exhaust steam Injector, screwing into the
casing a, at the lower end; d', being the screw plug for giving access when required
to the interior of the nozzles.
e,
is a branch for the overflow, screwed into the casing a, having a seating formed
in it for a cone valve e', having a stem which is guided in a hollow plug e², screwing
into the branch e, as shown.
The valve el, opens outwards.
In the delivery branch d, there is an ordinary back pressure valve f, closing
against the return of fluid which has passed from the Injector in casing a.
There is another casing a³, secured by flanges to the casing a, which casing a³, is
connected up to the pipe supplying Exhaust steam to the Injector.
In this casing a³, there is a swivel throttle valve g, of ordinary construction, on a
spindle g', passing through a stuffing box formed on the side of the casing a³.
In the casing a³, across its bore there is a cross bar ', which has a passage h³,
formed in it from the side of the casing a³, and to this cross bar h¹, a small nozzle h,

page_text: is screwed, that enters the exhaust steam nozzle b. The said passage h³, is in
connection with a pipe h³, which has a junction for another pipe h', which brings live
steam to the small nozzle h.
The additional supplementary live steam part of the Compound Injector is within
three casings.
One casing, contains a branch k¹, for connection with the live steam supply and
it is from this branch that the live steam is or may be taken by the pipe h*, to the
small nozzle h, in the exhaust steam Injector in casing a.
This casing k, has an inner branch into which the central live steam nozzle i, is
screwed for the supplementary Injector.
In the casing, the hinged flap combining nozzle, and the receiving and
discharging nozzle, which are constructed and inserted in the casing k², same as
these parts in the Exhaust steam Injector in casing a, there being a ring bar k*,
formed in the casing, to limit the opening movements of the hinged flap.
The delivery outlet is from a side branch k³, from the casing 2, and the valve f', is
constructed and arranged similar to the outlet valve e', for the overflow in the
branch e, casing a.
There is another flange junction on the casing ³, for the casing k*, though this
and the casing, may be formed in one piece, in which casing k', there is a valve
seating for a starting valve 1, opening outwards or from the injector. The spindle of
this valve 1, has a head ", which is acted upon by a diaphragm, secured by a plate ko,
to the flange, this plate ko, having a screwed junction for a pipe l, which communi-
cates with the casing k², and takes the pressure of the fluid at the delivery, before it
passes the back pressure valve f, so that when the pressure sinks at that point the
starting valve 1, can open to allow fluid to escape at a side branch, from the
casing, [see fig. 2].
When the jet has been established the full pressure of the fluid at the delivery,
acts upon the diaphragm and keeps the starting valve 1, closed.
The modification shown by fig. 2 is the same as that shown by fig. 1 except as to
the alteration required in the Exhaust Injector to suit the changed position of the
parts. The overflow valve e¹ and branch e, and back pressure valve f, being changed
in position as shown.
There is no change in the supplementary live steam part of the Injector in
casings k, 2, and, which in fig. 2 is an outside view of that Injector shown in fig. 1.
Fig. 9 is a longitudinal section and illustrates our improved combination, under
the first head of our invention, which is a modification of the compound Injector,
described in our aforesaid complete specification No. 5731-1887 and illustrated by
fig. 5 thereof.
It will be readily understood by inspecting the figure and comparing it with
figs. 1 and 2 hereinbefore described, and fig. 5 of our aforesaid complete specification
No. 5731-1887.
. The parts within or connected with the casings a, and a³, and the casings ², and k³,
are the same or are similar to those hereinbefore described in reference to figs. 1 and 2
except that the back pressure valve, fig. 1 is not shown in fig. 9 but may be used if
desired.
The casing for the live steam branch 62, and for the valve g, and its connected parts
are the same or are similar to those described in our aforesaid complete specification,
and illustrated therein by fig. 5.
Live-steam is taken from the casing for the live steam, marked b², by the pipe hª,
as shown, to supply the live steam to the small steam nozzle h, within the exhaust
steam nozzle b.
Fig. 10 is a longitudinal section of a compound exhaust and live steam injector
under the first head of our invention, which is a modification of that illustrated by
figs. 8 and 9 of our aforesaid complete specification No. 5731-1887.
Fig. 10 illustrates our improved form of the live steam part of the compound
exhaust steam and live steam Injector.
The exhaust steam part of the Injector [not shown]. may be the same as those

page_text: described in our aforesaid specification No. 5731-1887 or the same as the Exhaust
part of the Injector, which is combined with a small nozzle [h] for live steam
within the Exhaust steam cone [6] hereinhefore described and illustrated by
figs. 1 and 2. k*, is the junction flange, where the combined steam and water is
received from the exhaust part of the Injector, [not shown in fig. 10].
In the casing k, for this part there is a branch k', for the live steam; i, is the live
steam cone.
ix, is the first part of the combining cone, the other part i, of which is arranged
to slide in a part projecting from the discharging cone ³, which is constructed as
shown, and is screwed into the end of the casing k, as shown.
The moveable part 2, of the combining cone, has or may have three or more
guiding wings on its exterior to keep it central in the tubular part projecting from i³,
in which it slides.
When the injector is not working by reason of the jet not being properly
established, the movable part, of the combining nozzle is away from the fixed
part and this forms a space 2, for overflow the outlet from which is controlled by a
diaphragm valve l, as explained in reference to figs. 1 and 2.
When the jet is properly established the movable part, of the combining cone
comes close to the end of the fixed part i*, and thus closes the overflow spaco 1,
between them.
Fig. 11 is a longitudinal section of an injector in which two jets of live steam
direct from the boiler are used. It will be readily understood from the explanation
of our herein before described improvements.
v, casing; vl, branch for live steam; v³, the water supply branch; w, the live
steam nozzle;, the combining cone which may be a solid or hinged flap combining
cone, but in the example shown it is a solid combining cone; x, is the overflow
orifice, and 3, the overflow branch; &, valve acted upon by a spring to close the over-
flow outlet, the discharging cone; y, the back pressure valve.
The letters of reference for the second live steam injector are the same as those
used in figs. 1 and 2 hereinbefore described.
k, is the branch for the second jet of live steam; i, the live steam nozzle. Tho
hinged flap combining cone and the discharging cone is constructed and arranged in
the same manner as those parts herein before described in reference to figs. 1 and 2.
The automatic valve l, controlling the overflow from the flap nozzle is also arranged
the same as that described in reference to figs. 1 and 2. A back pressure valve is
not shown corresponding to the valve f, fig. 1, but may be used if required.
We wish it to be understood that though we have shown in figs. 1,2 9, 10 and 11
of the drawings herewith, the live steam in the centre [as we prefer] that is, in the
nozzle i, with the water or fluid from the injector in casing a, on its exterior, yet the
water or fluid may be in the centre and the live steam annular or on its exterior if
desired.
The third part of our invention relates to modes of applying our improved Injectors
to Locomotives to prevent waste of live steam and water.
As our improved Injector is worked by both Exhaust steam from the Engine or
Engines, and live steam from the boiler, it is obvious that it will cease to work, if the
supply of Exhaust steam stops, as when steam is shut off from the Engine, and this
occurs not only when a Locomotive is stopped, but also when steam is shut off when
the Locomotive is descending inclines.
If the exhaust steam is shut off the compound injector ceases to work, and the
live steam and water continues to be supplied but it is wasted.
The object of this part of our invention is to automatically shut off the live steam
and water, when the steam to the Engine or Engines is shut off. Or to turn on live
steam to supply the exhaust part of the Injector when the exhaust steam supply
ceases as when the steam is cut off from the Engine or Engines.
Fig. 3 is an end elevation and fig. 4 a side elevation showing so much of a loco-
motive as will be required to explain this part of our invention.
...The compound automatic Exhaust and supplementary live steam Injector represented

page_text: by figs. 1 and 2 is shown applied in figs. 3 and 4 as will be readily understood
by inspection of the figures.
m, is the stop valve controlling the supply of water from the Tender of the
locomotive which is brought by a flexible pipe m', coupled in the ordinary manner to
a pipe m², which is connected with the water branch of the Injector, but first passes
through a stop valve n, in a casing n', which is shown detached on an enlarged scale
in section by fig..
The spindle n', of this valve is connected by a rod n³, with a guiding link n',
having its fulcrum on a bracket attached to the frame of the locomotive, then a short
link is jointed to the link n', or rod n³, and to one end of a lever n³, having its
fulcrum n, on a bracket [see fig. 4] the other end of which lever being jointed with
a vertical rod n. [see fig. 3] which at its upper end is jointed to one arm of a bell
crank lever n, having its fulcrum on a bracket [not shown] carried on the framing,
the other arm of the bell crank lever n³, being connected by a rod n*, with the handle
of the regulator n', by which the steam is turned on and off to the Engine.
It will thus be seen that when the steam is turned on the water is turned on and
when the steam is turned off the water supply is shut off.
There is sufficient play or movement allowed in the connections to permit the water
valve to shut close when the steam is shut off or this is effected without play, if the
regulator handle is arranged to move slightly further in the direction for shutting off
the steam after the steam valve is shut.
There is a rod p, having a handle at its upper end, the lower end of which is
jointed to a lever secured on the end of the shaft or spindle 6, fig. 1, for adjusting
the water supply, and there is also a similar rod and handle q, for opening and closing
the throttle valve g, figs. 1 and 2.
r, is a pipe to convey away the overflow; live steam pipe; w, exhaust steam pipe;
x, delivery pipe from the compound Injector.
Fig. 6 shows detached a valve actuated by a diaphragm, connected with the water
branch [a] of the Injector.
This valve t, [in a casing t] is closed by a spring 2, and it is opened by the
pressure of steam acting upon the diaphragm 3, and the steam is conveyed by a
small pipe at t, [not shown] from the steam pipe supplying the Engine or Engines.
Thus when steam is shut off from the Engine or Engines, it is also shut off from
the diaphragm, the spring t², then closes the water valve t, and when steam is turned
on to the Engine or Engines its pressure upon the diaphragm 3, opens the water
valve t.
Fig. 7 is a detached view showing a valve u, in section applied to the live steam
branch [k, figs. 1 and 2] of the Injector, actuated by a diaphragm and the pressure
of steam.
In this case a spring is not required to close the valve u, as the pressure of the
steam tends to close it and is sufficient.
A branch from the small pipe [not shown] actuating the water valve [t, fig. 6]
will turn on and off the live steam passing through the valve u, fig. 7 in like manner.
Fig. 8 is a detached view showing both a water valve t, and live steam valve u,
combined together with a plate u', between two diaphragms, the small steam pipe
at t', [not shown] brings steam to act simultaneously upon both diaphragms and its
pressure opens the valves t, and u, and its absence allows them to close.
The arrangements illustrated by figs. 6, 7 and 8 are automatic substitutes for the
means illustrated by figs. 3 and 4.
When the water and live steam is to be constant, and live steam is to be used in the
Exhaust Injector in the absence of exhaust steam the live steam is brought to a
branch a, see fig. 2, into the Exhaust steam nozzles, [6], and this live steam is
automatically regulated by a valve and diaphragm similar to that shown by fig. 7
properly arranged and proportioned for the purpose.
Or a valve may be actuated by the regulator handle n°, fig. 3, to open the live
steam cock to the Exhaust steam Injector when the steam to the Engine is fully
shut off and vice versa when the steam is turned on to the Engine or Engines.
