IMPROVEMENTS IN CERTAIN PROVISIONAL SPECIFICATION
Year: 1865

page_text: LETTERS PATENT to Andrew Barclay, of Kilmarnock, in the County of
Ayr, North Britain, for the Invention of "IMPROVEMENTS IN CERTAIN
PROVISIONAL SPECIFICATION left by the said Andrew Barclay at the
Office of the Commissioners of Patents, with his Petition, on the
9th December 1865.
I, ANDREW BARCLAY, of Kilmarnock, in the County of Ayr, North
Britain, do hereby declare the nature of the said Invention of "IMPROVE-
MENTS IN CERTAIN APPARATUS FOR INJECTING AND EJECTING FLUIDS AND LIQUIDS,
to be as follows, that is to say :-
This Invention, which has for its essential objects the simplifying of the
construction of apparatus used for injecting and ejecting fluids or liquids, as
well as rendering such apparatus more efficient than hitherto, is based upon
an Invention for which Letters Patent were granted unto the said Andrew
Barclay on or about the 6th day of May 1864, and numbered 1151, and
consists as follows :-
The portion of the apparatus which contains the steam and water nozzles
is furnished at the end nearest the handles or wheels for regulating the flow
of the water. and steam with a flanch, into which four or other number of
pillars are fixed, being arranged to carry at their upper end another. similar
flanch which projects from and forms part of a tube, one portion of which ex-
tends downwards into the main body of the instrument, leaving an annular space

page_text: around it, whilst the other portion above the flanch has a screw thread formed
on it, which is used, as will herein-after be shown, for partly regulating the
feed. The main portion of the instrument has a stuffing box formed in it,
and is provided with a gland through which passes a tubular piece carrying
at its inner end the steam nozzle. This last-mentioned tubular piece is fur-
nished at its outer end with a flanch, into which two or more pillars are fixed;
these carry at their upper end a ring which fits into a circular recess formed
on the regulating wheel or handle, and by turning the wheel or handle upon
the screwed portion of the first-mentioned tubular piece the steam nozzles are
caused either to recede or advance. It should be mentioned that the tube
carrying the steam nozzle fits into and is capable of being moved upwards and
downwards in the annular space formed by the first-named tube and the body
of the instrument. Two of the pillars of the lower set and the two forming
the upper set are screwed, so that nuts may pass over them for tightening the
glands of the stuffing boxes which surround both the first and second named
tubular pieces. As it is desirable to have as much command as possible over
the quantity of feed at any given time, to further this object the spindle by
which the flow of the steam from the nozzles is regulated is under the
present Invention made hollow, and a solid spindle is passed down through
the opening; by means of this arrangement when the inner spindle is regu-
lated to give any, desired amount of opening to the flow of the water, and is
made to pass down into the, water nozzle for, the purpose of enlarging or
contracting the area of opening; by moving the outer ring the flow of the
steam can be varied or shut off as required. The hollow spindle, passes
through a stuffing box in the upper end of the second tubular piece.
Another feature, of this Invention consists in forming the valve. in the
throat of the apparatus of such a curved form that by means of this form
and the back pressure of the feed, water its area of opening is, made to exactly
correspond at any time with the area of opening of the water nozzle.
There are other modes of varying the actual area of the opening of the
nozzles, besides the one herein-before, referred to, viz., an air-tight box may
be cast on one side of the body of the apparatus, having in it a spindle, equal
portions of which have right and left screw threads cut on them; the spindle
passes through two pieces of metal of a quadrantal form, in which a set of
nozzles of various sizes are fixed, the use of the right and left hand screws
being that when it is required to shift the quadrantal piece by turning the
spindle in one direction these pieces are released from the actual nozzle and
throat of the instrument, so that it can be turned on its centre until a set of
holes which will give the required feed is brought round, when the spindle is

page_text: reversed and the quadrantal pieces are again brought close against the
nozzle and throat in manner suitable for working.
Besides the last-mentioned arrangement a cock may be made to revolve,
having holes or nozzles made in it of different sizes to correspond with.
variations of feed, the holes or nozzles being turned round to suit the feed
required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Andrew Barclay in the Great Seal Patent Office on the
9th June 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANDREW
BARCLAY, of Kilmarnock, in the County of Ayr, North Britain, send.
greeting...
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of December, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Andrew Barclay, Her special license that I, the said Andrew Barclay,
my executors, administrators, and assigns, or such others as I, the said
Andrew Barclay, my executors, administrators, or assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
CERTAIN APPARATUS FOR INJECTING AND EJECTING FLUIDS AND LIQUIDS," upon the
condition (amongst others) that I, the said Andrew Barclay, by an instrument
in writing under band and seal, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Andrew Barclay, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Drawings, and to the
letters and figures marked thereon, that is to say:
My said Invention, which has for its essential object the simplifying of the

page_text: -construction of apparatus used for injecting and ejecting fluids or liquids, as
well as rendering such apparatus more efficient than hitherto, is based upon
an Invention for which Letters Patent were granted unto me on or about
the 6th day of May 1864, and numbered 1151, and consists as follows:-
The portion of the apparatus which contains the steam and water nozzles is
furnished at the end nearest the handles or wheels for regulating the flow of
the water and steam with a flanch, into which four or other number of pillars
are fixed, being arranged to carry at their upper end another similar flanch
which projects from and forms part of a tube, one portion of which extends
downwards into the main body of the instrument, leaving an annular space
around it, whilst the other portion above the flauch has a screw thread formed
on it, which is used, as will herein-after be shown, for partly regulating the
feed. The main portion of the instrument has a stuffing box formed in it, and
is provided with a gland through which passes a tubular piece carrying at its
inner end the steam nozzle. This last-mentioned tubular piece is furnished
at its.outer end with a flauch, into which two or more pillars are fixed; these
carry at their upper end a ring which fits into a circular recess formed on the
regulating wheel or handle, and by turning the wheel or handle upon the
screwed portion of the first-mentioned tubular piece the steam nozzles are
caused either to recede or advance. It should be mentioned that the tube
carrying the steam nozzle fits into and is capable of being moved upwards and
downwards in the annular space formed by the first-named tube and the body
of the instrument. Two of the pillars of the lower set and the two forming
the upper set are screwed, so that nuts may pass over them for tightening the
glands of the stuffing boxes which surround both the first and second named
tubular pieces. As it is desirable to have as much command as possible over
the quantity of feed at any given time, to further this object the spindle by
which the flow of the steam from the nozzles is regulated is under the present
Invention made hollow, and a solid spindle is passed down through the
opening; by means of this arrangement the inner spindle is regulated to give
any desired amount of opening for the flow of the water, and is made to pass
down into the water nozzle for the purpose of enlarging or contracting the
area of opening; by moving the outer one the flow of the steam can be varied
or shut off as required. The hollow spindle passes through a stuffing box in
the upper end of the several tubular pieces.
Another feature of this Invention consists in forming the valve in the throat
of the apparatus of such a curved form that by means of this form and the
back pressure of the feed water its area of opening is made to exactly
correspond at any time with the area of opening of the water nozzle.

page_text: There are other modes of varying the actual area of the opening of the.
nozzles besides the one herein-before referred to, viz., an air-tight box may be
cast on one side of the body of the apparatus, having in it a spindle, equal.
portions of which have right and left screw threads cut on them; the spindle
passes through two pieces of metal of a quadrantal form in which a set of
nozzles of various sizes are fixed, the use of the right and left hand screw being
that when it is required to shift the quadrantal piece by turning the spindle in
one direction these pieces are released from the actual nozzle and throat of the
instrument, so that it can be turned on its centre until a set of holes which
will give the required feed is brought round, when the spindle is reversed and
the quadrantal pieces are again brought close against the nozzle and throat in
manner suitable for working.
Besides the last-mentioned arrangement a cock may be made to revolve,
having holes or nozzles made in it of different sizes to correspond with:
variations of feed, the holes or nozzles being turned round to suit the feed
required.
And in order that my said Invention may be properly understood, I shall
now proceed inore particularly to describe the system, mode, or manner in or
under which the same is or may be used or practically carried into effect,.
reference being had to the several Figures upon the two explanatory Sheets of
Drawings which I have hereunto appended, and in which similar parts are
indicated by corresponding letters of reference, that is to say :-
On Sheet 1, Figure 1 is a longitudinal section of one arrangement of my
improved apparatus for injecting and ejecting fluids; Figure 2 is a similar
section of another mode of arranging the apparatus.
In Figure 1 the lower part of the body of the instrument is composed of
three principal pieces A, A', and A³, which are screwed together in the manner
shown; the upper end of this part of the instrument is furnished with a flanch
B, which carries the four pillars C, two only of which are seen at Figure 1.
The four pillars C carry at their upper end the flanch D, and from the upper
and lower sides of this flanch the tubular pieces E and E' project, the upper
one having a square threaded screw formed theréon, as seen in the Figure.
The hand wheel F for regulating the opening of the water nozzles has a screw
thread cut in it to correspond with that on the tubular piece E¹, and the boss
of the wheel projects below to receive a flanch G, which is kept in place on
the boss by means of the collar H; from this flanch G two pillars I pass down-
wards through holes in the flanch D, and are thence continued on to the
flanch K, which carries the tubular piece or steam passage L and nozzle L',
by means of which the supply of water is regulated. As it is necessary that

page_text: the joint between the tubular piece L and the external body part A should be
air-tight, a stuffing box is provided at the upper end of the piece A, and a gland
M, having holes through which the pillars C pass, keeps the packing tight
therein, the pressure on the gland being regulated by the nuts on the screwed
portions of the pillars.
'
By means of this arrangement the great difficulty always hitherto experienced
in keeping tight the bottom packing of the tube carrying the water nozzles is
obviated, as the packing in the stuffing box can at any time be instantly
tightened up, or if required new packing may be rapidly filled in, so that the
inaccuracies of the working of the instrument on account of a leaky joint at
this part are prevented, and its continuous action is now made certain for any
length of time.
It is absolutely necessary when apparatus of this class is employed for
lifting liquids from great depths that the joint around the steam passage E
formed by the stuffing box and gland M, Figure 1, should be maintained
perfectly air-tight, otherwise the lifting efficiency of the instrument is much
impaired by air passing in around the steam passage, thereby destroying the
vacuum in the suction pipe and mixing with the water as it passes towards
the nozzles L' through the passage V, and as the apparatus according to the
several modifications comprised under this Invention is more especially
designed with the view of lifting liquids from much greater depths than
hitherto, the opening up of the outside body parts of the instrument, so that
the packing around the steam passage may be instantly adjusted without the
necessity of taking any part of the instrument asunder, is considered the special
feature and main improvement as comprised under these present Letters
Patent.
. It is to be understood that the remarks in this immediately preceding clause
apply equally to the three succeeding modifications herein-after specified. The
admission of steam through the nozzles in this modification is regulated in the
usual manner by means of a central spindle O¹, the screwed part of which
passes through a hole correspondingly cut in the inner projection Os of the
tube E, E. The steam inlet is indicated by the dotted circular lines
W; V, is the water inlet, and X the overflow; Y being the valve by which
direct communication with the boiler is prevented when the instrument is not
feeding.
In Figure 2, Sheet 1, the general arrangements are much the same as
that described and shown in reference to the first modification, and the same
figures or letters of reference are affixed to parts corresponding to those in
Figure 1, and therefore need not be again referred to. The chief peculiarity

page_text: in the second modification consists in so arranging the instrument that the
regulating wheel F, together with the screw arrangement, flanch G, and pillars
I, constituting the gear by which the admission of water is regulated as at
Figure 1, is in this case dispensed with. A three-sided flanch M is formed
on the tubular piece, Figure 2, and the part A of the body of the instrument
is provided with a corresponding flanch; the two parts are connected together.
by studs C.
A stuffing box is formed in the upper part of the tubular piece A, and the
gland N secures the packing therein, forming a perfectly tight joint around the
piece O being pressed down by nuts in the usual manner. The piece O
carrying the water nozzle L is regulated by means of the screw P, which turns
in a lug P¹ cast on one side of the piece O. A stuffing box is also formed at
the upper part of the piece O, by which a perfect joint is maintained between it
and the inner tubular piece O¹, through which the steam passes on to the nozzles.
The central spindle Q, by which the admission of the steam is regulated, iş
adjusted in the usual manner by means of the screw R, the spindle pussing
through a stuffing box S, and surmounted by a hand wheel T, by, which it
is actuated. The advantages resulting from this second modification of
my Invention are similar to those previously described and referred to as
belonging to the first arrangement.
On Sheet 2, Figure 1 is a longitudinal section of the third modification of
my Invention. In this arrangement the lower part of the instrument is also,
made of three parts A, A¹, and A³, as in the first modification, and the upper
part A is furnished with a flanch for carrying the pillars B, by which the
upper and lower exterior and main parts of the instrument are connected:
In order to obtain easy access to the packing of the inner tube C, with the
view of rendering the joints between it and the outer parts of the instrument
more firm and secure, stuffing boxes D and D' are formed in the upper and
lower exterior portions, and glands E and E' are respectively provided to
keep the packing tight, the pillars B baving screw threads cut on them and
provided with nuts, as shown in the Figure, by which the tightness of the joints:
are regulated.
Figure 2 shows, in horizontal section, the passages in the tube C by which
the steam is admitted on its way to the nozzles. For regulating the supply of
water the tube C is furnished with a hand wheel F, by which the tube is
turned in its screw bearing G, formed in the upper main portion of the
instrument. The central spindle H for regulating the flow of steam through,
the nozzles is also operated in manner similar to that shown and described in
reference to the two previous modifications. As all the parts not described.

page_text: in reference to this modification are similar to those shown in the two previous
arrangements, and are common to apparatus of this class, it is not considered
in the present case necessary to refer to them.
Figure 3, Sheet 2, represents a fourth modification of my said improvements
in apparatus for injecting and ejecting. In this case the general arrangement
is much the same as that shown in the herein-before described third modifica-
tion, with the exception that in place of regulating the admission of water by
means of a hand wheel on the tube C, in this case it is regulated by the screw
I passing through the upper and lower flanches A and A* respectively, a collar
K being placed on its lower end to prevent its position with respect to these
flanches being altered. A lug L is cast on one side of the tubular piece C, and
the screw I passes through a corresponding screw threaded hole cut therein,
so that as the screw I is turned either in a right or left hand direction the tube
C and the water nozzles L' are accordingly raised or lowered. In both Figures
1 and 3, Sheet 2, M is the steam passage; N, the water passage; and O, the
overflow. As shown in all the Drawings of the four modifications on the
accompanying Sheets 1 and 2, I prefer to employ the hollow nozzles described
in the Specification of former Letters Patent granted unto me on or about the
6th day of May 1864, numbered 1151, for "Certain Improvements in Appa-
ratus for Injecting and Ejecting Fluids and Liquids." The nozzle is constructed
by means of the cavity in the outer piece a being made of larger diameter than
the outer diameter of the inner piece b, so that a space, shown by the darkly
shaded parts in Figures 1 and 2, Shert 1, and Figures 1 and 3, Sheet 2, is
left between them, this space may be allowed to remain as an air space or may
be filled with non-conducting material as described in the Specification of
the Letters Patent herein-before referred to.
•
b
At Figure 4, Sheet 2, is shown one mode of arranging and applying a
variable set of nozzles. In this arrangement a parallel cylindrical opening
is made right through the body of the instrument at that part wherein the
nozzles cand throat d of the instrument are situated. A tubular piece A
having a set of nozzles a of various sizes and throat pieces 6 corresponding to
them are fixed in opposite sides of this tubular piece, and as the ends of the
actual nozzle c and throat d are constructed to correspond and fit against the
exterior surface of the tubular piece A, any one of the various nozzles an
throats situated in this piece A may at once be applied by sliding the piece
A through the opening until the nozzle and throat necessary for producing
the required feed are brought into position to enable the instrument to work.
Instead of constructing the variable nozzles and using the mode of applying
them as shown at Figure 4, Sheet 2, they may be constructed of two quad-

page_text: rantal or circularly formed pieces as described in an earlier part of this
Specification; what I consider specially as my Invention at this point is the
application of a variable set of nozzles and throats to apparatus of the class to
which these present Letters Patent refer.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in or under which the same is or may be used or
practically carried into effect, I would observe, in conclusion, that I do not con-
fine or restrict myself to the precise details herein-before given, as many
variations may be made therefrom without deviating from the true principle or
main features of my Invention; but what I consider novel and original, and
therefore claim as the Invention secured to me by the herein-before in part
recited Letters Patent, is,-
First, the general arrangement and construction or mode of combining the
several parts of apparatus to be used for injecting and ejecting fluids,
substantially as herein-before described.
Second, the joining together or connecting of the exterior main portions of
the instrument by means of pillars, or studs, or otherwise, as herein-before
described.
Third, the arranging of the instrument so that the joints around the
steam passage are rendered accessible on account of the space between the
upper and lower parts being opened up or left open in such manner as to
allow of glands and stuffing boxes being at once adjusted or repacked without
necessitating the taking asunder of any parts of the instrument.
Fourth, the constructing of the instrument in such manner that the packing
and gland or glands around the steam passage are accessible from the exterior
parts of the body or main portion of the apparatus.
Fifth, the application of a set of variable nozzles and throats to apparatus
of the kind herein-before described in the manner specified, or any mere
modification thereof.
In witness whereof, I, the said Andrew Barclay, have hereunto set my
hand and seal, this Seventh day of June, One thousand eight hundred
and sixty-six.
