I THOMAS HENRY WILLIAMS, of 11 Queen Victoria Street, in the City of London,
in the County of Middlesex, Engineer, do hereby declare the nature of this invention
to be as follows:-
:―
My invention relates to injectors and consists in the combination and arrange-
ments of one or more flexible discs, diaphragms, cones, cylinders, or their equivalents,
with the lifting combining, and delivery nozzles either together or separately, for the
purpose of effecting the automatic adjustment or regulation of one or more of the
several nozzles, whereby their respective functions are performed in a more certain
and reliable manner than has hitherto been obtained in practice with other injectors or
apparatus of a similar class, and whereby the automatic starting and restarting, or
the formation and reformation of the jet is effected, and maintained, more readily and
positively under all conditions and in any position, either through the reaction of the
jei only on the said flexible disc, diaphragm, cone, or cylinder, or through the com-
bined influence of the reactive force of the said jet and the vacumn formed either
within the nozzle, or any chamber or compartment within which the nozzle may be
enclosed, or through the combined influence of a vacumn and atmospheric pressure,
or by means of all or any of the said influences acting either together or separately
in a suitable manner on one or more of the flexible discs, diaphragms, cones, or
cylinders, or their equivalents. My invention further provides for the automatic
regulation of the supply of water according to the pressure of the steam. My
invention is applicable to injectors worked by low pressure steam, such as the
exhaust steam from steam engines, equally as well as those worked by high pressure
steam.
In the practical application of my invention the steam nozzle is fitted in the top
of the body or case, of the injector in the usual manner, and the lifting nozzle is
mounted in an inner frame which is inserted from the lower end of the body or case
and is a free but tight fit therein. The combining and delivery nozzles are preferably

page_text: formed in one piece and are connected to the inner frame by a flexible disc
diaphragm, cone, or cylinder in such a manner as to divide or separate the overflow
chamber from the delivery. The said inner frame is fitted to work fluid tight within
the outer case or body of the injector, and is supported therein by a movable cap
screwed on to the lower end of the said outer case or body, the cap being connected
to the inner frame by a plug screwed into the base of the latter, and free to turn on
the said plug so as to impart a longitudinal movement to the inner frame, thus
forming a device by means of which the lifting nozzle may be adjusted with respect
to the steam nozzle to regulate the supply of water according to the steam pressure.
A suitable index and scale may be formed on the cap and outer case of the injector for
the purpose of guaging the supply of water to the steam.
A convenient form of flexible connection I find to be a corrugated metal truncated
cone, one end of which is fixed to the compound combining and delivery nozzle, and
the other to the inner frame by suitable screws, nuts, or their equivalent. Instead of
making the inner frame in one piece it may be made in two or more sections as
convenience of construction demands. Suitable openings are formed in the inner
frame to permit of the free passage of the overflow reaching to its outlet, and the
delivery to the boiler or other connection. When the corrugated cone is arranged
with its apex downwards-in which position it may catch any deposit which may
interfere with its flexibility- connect the lower end of the corrugated cone with the
internal bore of the combining nozzle by a suitable passage, so that when a vacumn,
or partial vacumn, is formed within the passage any deposit or sediment may be
forced out of the coned cylinder by the atmosphere through the passage and removed
by the jet, and thus keep the flexible connection clean.
The action of this injector is as follows:-Steam being turned on, and the jet
formed, the reactive force of the jet acts upon the flexible connection, causing a
movement of the compound combining and delivery nozzle which closes the aperture
between the combining and lifting nozzles, and so prevents the overflow of steam and
water, other than through the overflow formed in the compound combining and
delivery nozzle, in the well known manner. The compound combining and delivery
nozzle is retained in this position by the reactive force of the jet so long as the action
of the said jet is unimpared. Should the action of the jet cease, or otherwise be
impared, the compound combining and delivery nozzle is restored to its normal
position by the reaction of the said flexible connection, to be again acted upon by
the reactive force of the said jet when reformed. It will thus be seen that this
injector will work in an inverted or any other position in which it may be placed, as
the action of the moving nozzle, fixed to and operated by the flexible connection, is
not affected by the position in which the injector is fixed.
When it is not of importance that the lifting, combining and delivery nozzles should
be capable of being withdrawn together from the case or body of the injector, I fix
the lifting nozzles in the case of the injector in the ordinary manner, and I form
the combining and delivery nozzles in one piece and support it by a flexible disc,
diaphragm, cone or cylinder, connected to both the compound nozzle and the case
of the injector, the upper or lower end of the compound nozzle being guided by a
suitable seating formed within the case, or by means of a duplex flexible attachment
should such be necessary.
As a modification 1 sometimes fix the delivery nozzle to the case of the injector and
support the combining nozzle by the flexible disc, diaphragm, cone, or cylinder, the
steam and lifting nozzles being fixed to the case of the injector in the usual manner.
In this case the chamber both below and above the flexible connection are connected
with the overflow. Another modification has the lifting and combining nozzles formed
in one piece fixed to the body or case of the injector, while the delivery nozzle is
mounted on a flexible disc, diaphragm, cone, or cylinder attached to the interior of
the body or case of the injector, the top of the nozzle being guided on the end of the
combining nozzle if desired. A further modification consists in fixing the delivery
and combining nozzles to the body of the injector, and mounting a combined steam
and lifting nozzle on a flexible diaphragm, disc, cone, or cylinder.

page_text: When it is desired to automatically regulate the supply of water according to the
pressure of steam I mount the steam nozzle on two flexible discs, diaphragms, cones,
cylinders or their equivalents, one connecting it to the top of a chamber connected
with the steam inlet, and the other connecting it to the bottom thereof, the effective
area of the former being considerably greater than that of the latter. The lower end of
the steam nozzle extends as close to the lifting nozzle as will allow the apparatus to
work with the minimum pressure of steam. As the steam pressure increases so it acts
on the flexible connections and deflecting the top one due to its larger effective arca
lifts the nozzle and so allows more water to pass into the injector, the nozzle
automatically rising and falling with the increase or diminution of the steam pressure.

Improvements in and relating to Injectors.
I, THOMAS HENRY WILLIAMS of 11 Queen Victoria Street in the city of London in
the county of Middlesex, 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
:-
My invention relates to injectors and consists in the combination and arrangement
of one or more flexible diaphragms, discs, cones, cylinders or their equivalents, with
the steam lifting, combining, and delivery nozzles, either together or separately, for
the purpose of effecting the automatic adjustment or regulation of one, or more of the
several nozzles, whereby their respective functions are performed in a more certain
and reliable manner than has hitherto been obtained in practice with other injectors or
apparatus of a similar class, and whereby the automatic starting and restarting, or the
formation and reformation of the jet is effected and maintained more readily and
positively under all conditions and in any position, either through the reaction of the
jet only on the said flexible, discs, diaphragms, cones or cylinders, or through the
combined influence of the reactive force of the said jet, and the vacumn formed either
within the nozzle, or any chamber or compartment within which the nozzles may be
enclosed, or through the combined influence of a vacumn and atmospheric pressure,
or by means of all or any of the said influences acting either together or separately in
a suitable manner on one or more of the flexible discs, diaphragms, cones or cylinders
or their equivalents. My invention further provides for the automatic regulation of
the supply of water according to the pressure of the steam, or for the regulation of
the supply of steam according to the temperature and supply of water for its conden-
sation. My invention is applicable to injectors worked by low pressure steam, such as
the exhaust steam from steam engines, equally well as those worked by high pressure
steam.
I carry my invention into practical effect in the manner illustrated in the accom-
panying drawings, throughout which similar parts are marked with like letters of
reference.
Figure Sheet No. 1 is a view in sectional elevation of an injector having the
combining and delivery nozzles mounted on a flexible diaphragm consisting of a
corrugated metal truncated cone.
The steam nozzle A and the lifting nozzle B are fixed in the usual manner in the
body of the injector, and the combining nozzle C is made in one with the delivery
nozzle D, and is carried by a flexible diaphragm E taking the form of a corrugated
and truncated cone, and is guided by webs c, c fitting in a guide formed in or on the
body of the injector.
Figure 2 Sheet No. 1 is a view in sectional elevation of an exhaust steam injector
in which the steam nozzle A and the compound lifting and combining nozzle B, C, is
fixed to the body of the injector, and the delivery nozzle D is mounted on a flexible
diaphragm E, taking the shape of a corrugated and truncated cone, and is guided by
webs c, c, fitting in a guide formed in or on the body of the injector.
Figure 3. Sheet No. 2 is a view in sectional elevation of an injector in which the
steam nozzle A, the lifting nozzle B, and delivering nozzle D, are fixed in the body of

page_text: the injector in the usual manner. The combining nozzle is independent of the other
nozzles and is mounted on a flexible diaphragm E which is in form a corrugated
truncated conc. The lower end of the nozzle C is guided by the webs c, c in a tubular
extension of the delivery nozzle D.
Figure 4. Sheet No. 2. is a view in sectional elevation of an injector in which
the steam nozzle A, and the lifting nozzle B, are formed as one and are mounted on
and supported by three flexible diaphragms E, E and E² each taking the shape of a
corrugated and truncated cone, while the compound combining nozzle and the
delivery nozzle D are formed in one and are fixed in the body of the injector.
Figure 5. Sheet No. 3 is a view in sectional elevation of an injector having the
steam nozzle A. mounted on flexible diaphragms E1 and E2 whereby the supply of
water is automatically regulated to the supply of steam. The lifting nozzle. Bis
secured to an inner frame or casing F and forms a part thereof, and the combining.
nozzle C and the delivery nozzle D are formed in one piece and are mounted on a
flexible diaphragm E as hereinbefore described.
The free end of the combining nozzle C is guided by the webs e, e fitting in a tubular.
guide formed on the said inner frame or casing F as shown.
Figure 6 Sheet No. 3 is a view in sectional elevation of an injector having the lifting
nozzle B formed in one piece with an inner lantern frame or casing F in which the
steam nozzle A is fitted as shown, or otherwise formed in one piece therewith.
The combining nozzle C, and the delivery nozzle D, are formed in one piece and are
mounted on a flexible diaphragm E, as hereinbefore described. The free end of the
combining nozzle C is guided by the webs c, c, in a tubular guide formed on the inner
frame or casing F, as before described. A valve a is mounted on a flexible corrugated
diaphragm E and works in conjunction with the steam nozzle A which is suitably
formed therefor, by which means the supply of steam is automatically regulated to the
supply and temperature of the water.
Figure 7. Sheet No. 4 is a view in sectional elevation of an injector having a split
compound lifting & combining nozzle B (controlled by a flexible diaphragm E.
Figure 8 Sheet No. 4 is a view in sectional elevation of an injector in which the
overflow aperture between the lifting nozzle B and the combining nozzle C is
controlled by a flexible diaphragm E carrying a valve e.
Figure 9 Sheet No. 2 is a view in sectional elevation showing a method of applying
my invention to injectors already constructed.
Referring to the arrangement illustrated by Figure 1. Sheet No. 1. the action is as
follows: The compound combining and delivering nozzles CD being in the position
shown, and steam turned on, the steam escapes through the overflow apertures f,
and until the water enters the lifting nozzle B, whereupon it condenses the steam,
which imparts a high initial velocity to the jet so formed in the well known manner.
The force of the jet reacts upon the flexible diaphragm E which divides the delivery
chamber from the overflow chamber, thereby causing its deflection, and the consequent
movement of the compound combining and delivering nozzles C, D, thus closing the
overflow aperture f, and preventing the further escape of steam and water other
than through the usual overflow f¹ which also ceases upon the action of the jet being
completely established.
The nozzles CD are retained in their position, and the overflow f kept closed by
the reactive force of the jet on the flexible diaphragm E so long as the action of the
said jet remains unimpaired. Should the action of the jet cease or otherwise be
impaired, the compound combining and delivery nozzles CD is restored to its normal
position through the reaction of the flexible diaphragm E to be again acted upon by
the reactive force of the jet when reformed in the manner described.
Referring to the arrangement illustrated by Figure 2. Sheet No. 1 (which illustrates
one application of my invention to an exhaust steam injector) the general action is
similar to that in the preceding example. One overflow aperture f' only is provided,
and when the instrument is inactive the distance. between the compound lifting and
combining nozzle C, and the delivery nozzle D, is greater than in ordinary injectors

page_text: thereby providing for a freer escape of the steam and water on starting than is obtained
in other corresponding overflow aperture of ordinary injectors. When the exhaust
steam enters and the jet is formed in the well known manner, the reactive force of the
jet in the delivery chamber deflects the flexible diaphragm—which divides the delivery
chamber from the overflow chamber-and the movement thus imparted to the delivery
nozzle D effects a contraction of the overflow aperture f¹ to its working limit, but
does not completely close it. The diaphragm E and delivery nozzle D are retained in
their position so long as the jet continues in action, and are returned to their normal
position upon the jet ceasing to act or otherwise being impaired, in the manner
before described.
Referring to the arrangement illustrated by Figure 3 Sheet No. 2. the action is as
follows: Steam being admitted to the steam chamber and nozzle A, it escapes through
the overflow apertures and f¹ until water enters the lifting nozzle B, and the jet is
formed in the well known manner. Through the combined condensation of the steam
and the rapid passage of the jet past the overflow aperture f, a partial vacumn is formed
in the chamber surrounding the lifting, nozzle B. This chamber being separated from
the usual overflow chamber by the flexible corrugated diaphragm E. The opposite
side of the diaphragm is acted upon by the atmosphere, the pressure of which deflects
the diaphragm thereby causing the combining nozzle C to close on to the lifting
nozzle B to seal the overflow aperture f. The flexible diaphragm E and the combining
nozzle Care retained in their position so long as the jet continues to act, and maintains
a sufficient vacumu within the lifting nozzle B, the combining nozzle C, and the said
vacumn chamber which surrounds the lifting nozzle. To facilitate maintaining the
vacumn in the said vacumn chamber, the air may be excluded therefrom by means of
a suitable water trap, as illustrated, in which the overflow water collects and seals the
opening which communicates with the interior of the vacumn chamber and the
atmosphere, or the said opening may be closed by a suitable valve arranged to open
outwards for the escape of the steam and water on starting, and to close and seal tho
said opening on the formation of the vacumn and jet.
Should the jet cease to act or be otherwise impaired the combining nozzle C is
restored to its normal position through the reaction of the flexible diaphragm E, and
the overflow aperture is thereby opened, to be again closed upon this reformation of
the jet and vacumn as before described.
Referring to the arrangement illustrated by Figure 4. Sheet No. 2, the action is as
follows:- -Steam being on and the jet formed as before described, a vacumn (or partial
vacumn) is formed within the lifting nozzle B, the combining nozzle C, and the over-
flow chamber. The atmosphere within the water chamber acting upon the flexible
diaphragm E and the lifting nozzle B causes a deflection of the diaphragins E, E¹ and E²,
and a consequent movement of the steam nozzle A and the lifting nozzle B, thereby
seating the lifting nozzle B on to the combining nozzle C, and closing the overflow
aperture f. The aperture fis thus kept closed so long as the jet acts, and the vacumn
within the lifting and combining nozzles is maintained. Should the jet cease to act or
otherwise become impaired the lifting and steam nozzles are restored to their normal
positions through the reaction of their respective diaphragms, and the overflow
aperture is thereby opened, to be again closed in the manner before described upon
the vacumn and jet being reformed.
The
The diaphragms El and E, are so proportioned and arranged that the pressures
acting thereon balance each other. The top side of the diaphragm E2 communicates
with the atmosphere through an opening v provided in the top or cap of the injector,
and the diaphragm E2 divides the steam chamber from the atmosphere.
diaphragm E divides the steam chamber from the water chamber, and the
diaphragm E divides the water chamber from the overflow or vacumn chamber. It
will be obvious that pistons formed on the steam nozzle, and fitting in suitable
cylinders, and free to move therein, may be substituted for the diaphragms E and E²,
or the steam nozzle may be fixed in the body of the injector in the usual way, and
the lifting nozzle B may be mounted independently on the flexible diaphragm E. In

page_text: either case the closing of the aperture would be effected by the preponderance of
atmospheric pressure acting on the diaphragm, upon the formation of the vacumn as
before described.
Referring to the arrangement illustrated by Figure 5 Sheet No. 3, the action is as
follows: The steam on entering the steain chamber acts upon the flexible dia-
phragm E, and the flexible corrugated tube or cylinder E. By virtue of the greater
acting area of the diaphragm E, the steam pressure thereon overcomes the pressure
on the steam nozzle A and the resistance of the flexible corrugated tube or cylinder E¹,
thereby deflecting the diaphragm E until the resistance due to the resiliency of the
diaphragm E2, and the corrugated tube or cylinder El balances the steam pressure.
The deflection of the diaphragm E effects a corresponding movement of the steam
nozzle A (which is mounted on the said diaphragm) which in consequence thereof
recedes from the lifting nozzle B as the diaphragm E' deflects with the increasing
pressure, and approaches thereto as the said diaphragm and the corrugated tube or
cylinder E resume their normal position through their resiliency as the steam
pressure acting thereon decreases. Thus the annulus formed by the free end of the
steam nozzle A and the lifting nozzle B is automatically increased and diminished
according as the pressure and consequent temperature of the steam increases or,
diminishes. By this means the requisite supply of water is automatically regulated
to suit the pressure and temperature of the steam, and to effect its condensation,
whereby the efficient and uniform action of the apparatus is maintained. When it is
desired to adjust or regulate the instrument to work with water of different temperatures
I provide a spring G in combination with the flexible diaphragm E2 and a suitable
adjusting nut g¹ for increasing or reducing the tension of the spring to suit the pressure
of the steam and the temperature of the water. The rod g is provided with a shoe at
one extremity which carries the said spring, and presses upon the top of the steam
nozzle A. At the other extremity is attached an index g², and the screw adjustment is
provided with a corresponding suitable scale of degrees to indicate the temperature of
the water. If the temperature of the water be low, the tension of the spring is
increased until the index points to the number on the said scale which corresponds to
the temperature of the water. The increased resistance thus offered to the steam
pressure through the combined action of the spring G and the diaphragm E² limits
the movement of the steam nozzle A for a given pressure of steam, and consequently
reduces the supply of water to the required amount to effect the condensation of the
steam and secure the efficient formation of the jet and consequent action of the
injector. If the temperature of the water be high, a larger volume will be required
to effectually condense the steam of the given pressure in order to secure the reliable
action of the injector, in which case the tension of the spring G is reduced until the
index points to the number on the scale which corresponds to the higher temperature
of water. The reduced resistance of the spring G and diaphragm E permits the
steam nozzle A to recede further from the lifting nozzle B, thereby increasing the
supply of water to suit the changed condition and to effectually condense the steam.
The top side of the flexible diaphragm E2 is placed in direct communication with
the atmosphere by means of the hole in the cap of the injector as illustrated, or by
any other suitable means.
The jet being formed in the well known manner the general action of the injector
is the same as described in previous examples, such as that illustrated by Figure 1.
Sheet No. 1. The supply of water may also be regulated by adjusting the position of
the inner frame F by means of the hand wheel W, whereby the annulus formed by
the steam nozzle A and the lifting nozzle B may be increased or diminished.
Obviously the automatic water regulator may be modified to operate a valve in the
water chamber or supply pipe instead of the steam nozzle as described, and the steam
nozzle may be fixed in the body of the injector in the usual way. Such an arrange-
ment may be effected by fixing the flexible diaphragm in a separate chamber on the
water inlet, one side of which is in communication with the steam supply, and the
other side in communication with the atmosphere or water space or inlet, and to
which is secured a suitable valve for regulating the supply of water.

page_text: Referring to the arrangement illustrated by Figure 6 Sheet No. 3. the action is as
follows: The steam on entering the steam chamber and steam nozzle A acts upon
the flexible diaphragm E' and deflects it until the resistance due to the resiliency of
the said diaphragm, and the spring G balances the steam pressure, thereby causing
the valve à to approach the top of the steam nozzle A and contract the steam
inlet of the said steam nozzle, whereby the supply and consequent pressure
of steam to the nozzle A is correspondingly reduced and adjusted to the supply of
water when it is constant, which is the case when the steam nozzle A and the lifting
nozzle B are fixed relatively to each other, and the annulus forined thereby remains
constant. The spring G, guide rod g and regulator glare provided for adjusting the
resistance of the diaphragm etc. when it is necessary to further adjust or regulate the
supply of steam to suit an increased or diminished temperature of supply or condensing
water. A suitable index and scale may be also provided to facilitate adjustment.
The top side of the diaphragm E' communicates with the atmosphere through the
hole in the cap of the injector as illustrated, or by other suitable means.
Obviously an automatic steam reducing or regulating valve may be fitted to the
steam inlet or pipe of the injector, instead of to the steam nozzle A as described.
When so modified the flexible diaphragm and steam valve are fitted in a separate
chamber independent of the steam nozzle A, and attached either to the steam inlet of
the injector or to the steam supply pipe thereof. In which case the steam nozzle A
and lifting nozzle B may be fixed to the body of the injector in the usual way,
instead of being formed in one with the inner frame F¹ as illustrated.
The jet being formed in the well known manner, produces a vacumn in the lifting
and combining nozzles B and C and in the passage d, which is provided in the
compound combining and delivery nozzle CD. The overflow water and any
sediment which may have collected in the flexible truncated cone diaphragm E is
consequently forced through the passage d by the atmospheric pressure, and removed
by the jet, thus preventing the accumulation of sediment which might interfere with
the flexibility of the said diaphragm E. The general action of the injector is
identical with that hereinbefore described with reference to Figure 1. Sheet No. 1 and
Figure 5 Sheet No. 3 of the accompanying drawings.
Referring to the arrangement illustrated by Figure 7 Sheet No. 4. which illustrates
an injector of the split nozzle type which is worked by low pressure steam, such as
the exhaust steam from a steam engine, the action is as follows:-
The steam being turned on enters the steam nozzle A and escapes through the split
compound lifting and combining nozzle B C to the overflow chamber, until water
enters the said nozzle B C, and forms the jet. The water which enters the delivery
chamber also enters the passage a and acting upon the flexible diaphragm E which
is connected to the hinged flap of the split nozzle B C, deflects the diaphragm E and
thereby closes the said hinged flap of the split compound lifting and combining nozzle B, C,
and prevents further waste of steam and water other than that which escapes through
the ordinary overflow aperture f" in the usual manner. So long as the jet continues
in action its reactive force on the flexible diaphragm E keeps the hinged flap of the
split compound lifting and combining nozzle B C closed. Should the jet cease to act
or otherwise become impaired sufficiently to reduce the pressure behind the
diaphragm, and in the passage a, the hinged flap of the compound nozzle B C opens
through the reaction or resiliency of the flexible diaphragm E to be again closed upon
the reformation of the jet by its reactive force on the said diaphragm in the manner
before described.
Referring to the arrangements illustrated by Figures 8 and 9 Sheet No. 4, which
illustrate injectors worked by high pressure, or live steam direct from the steam
boiler or other supply, their action is as follows:-Steam being turned on it escapes
into the overflow-chambers through the overflow aperture f, and away to waste in th
usual manner, until water enters the lifting nozzle B and combining nozzle C, and
forms the jet in the well known manner. The reactive force of the jet or waste
through the passage on the flexible diaphragm E deflects the same, and the valve e
which is mounted on the said diaphragin seals the overflow aperture formed in the

page_text: overHow or vacuum chamber surrounding the lifting nozzle B and combining nozzle C,
thus preventing the further escape of steam and water and excluding the air from the
said chamber. The overflow aperture remains sealed by the valve e so long as the jet
continues in action. On the jet ceasing to act from any cause whatever or should its
action be sufficiently impaired to reduce the pressure behind the flexible diaphragm E,
the valve e recedes and opens the overflow aperture through the reaction or resiliency
of the said diaphragm E, thus permitting the steam and water to freely escape from
the said vacuum, or overflow chamber in order to reestablish the said jet and action
of the injector, whereupon the valve e again closes the overflow aperture through the
reactive force of the said jet on the said flexible diaphragm E. is the usual over-
flow aperture. In the injector illustrated by Figure Sheet No. 4 communication
between the delivery chainber or pipe and the flexible diaphragm E, is effected by
means of the pipe or tube which illustrates a method of applying my invention to
existing injectors of a similar type.
Although the flexible diaphragms have herein before been referred to as made of
metal, and illustrated in the form of corrugated truncated cones or cylinders they may
be made of any other suitable material, and in any other suitable shape or form, that
will give the necessary deflection & resiliency.
It will thus be seen that this injector will work in an inverted or any other position
in which it may be placed, as the action of the moving nozzle fixed to and operated
by the flexible connection is not affected by the position in which the injector is
fixed.
I would have it understood that all the arrangements hereinbefore described, with
suitable modifications, are equally applicable to injectors worked by low pressure
or exhaust steam, as that one particularly described and illustrated by Figure 2.
Sheet No. 1 of the accompanying drawings.
It will be obvious that the flexible diaphragms and fixed nozzles may be con-
structed and arranged in other ways than those illustrated in the accompanying
drawings, and I lay no claim to any particular method of fixing the said flexible
diaphragms and nozzles. I also lay no claim to any particular construction of the
body of the injector or to the methods by which the nozzles may be withdrawn,
those illustrated in the accompanying drawings being merely intended to illustrate
some methods of carrying the same into practical effect.
I would have it therefore understood that I do not limit myself to the exact con-
struction and arrangement of the parts hereinbefore described and shown, but hold
myself at liberty to make such changes and alterations as fairly fall within the spirit
and scope of my invention.
Having now particularly described and ascertained the nature of my said inven-
