Year: 1875

page_text: LETTERS PATENT to William Oleland, of Linacre, in the County of
Lancaster, Gas Works Manager, for the Invention of “IMPROVE-
RENTS IN JET APPARATUS FOR GIVING MOTION TO FLUIDS."
Sealed the 20th December 1875, and dated the 24th June 1875.
PROVISIONAL SPECIFICATION left by the said William Oleland at the
Office of the Commissioners of Patents, with his Petition, on the
24th June 1875.
I, WILLIAM CLELAND, of Linacre, in the County of Lancaster, Gas
Works Manager, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN JET ÄPPARATUS FOR GIVING MOTION TO FLUIDS," to be
as follows:-
:
The object of this Invention is to provide means whereby when a jet
of elastic fluid used as motive power is caused to act directly on the
fluid to be moved, such jet shall be capable of adjustment so as to act
more advantageously when the quantity of either the moved or motor
fluid is variable or the pressure or resistance varies, and consists—
First. In so arranging a series of induction pipes or mixing nozzles of

page_text: different sizes that any of such nozzles can be readily brought into
position to allow of the more efficient action of the motor fluid. The
induction pipes or nozzles may be fitted in a disc arranged so as to be
revolved, or they may be fitted in a cylinder or on a slide, the object in
all cases being to bring the desired one into position.

Second. In employing what I call articulated induction pipes or
mixing nozzles. The different lengths or articulations of such induction
pipes are so arranged that they can be readily connected and dis-
connected so as to form induction pipes of several different sizes, so that
those best adapted to the resistance or quantity of the fluid to be moved, 10
or to the quantity or pressure of the motor fluid, can be readily brought
into action.
Third. In the use of a sliding, telescopic, or otherwise adjustable
projector for the jet of motor fluid, so that such motor fluid may issue
from the projector at any desired point in rear of the induction pipe or 18
at any point in the induction pipe itself.
Fourth. In employing a sliding, telescopic, or otherwise adjustable
induction pipe, so that the said induction pipe may be lengthened or
shortened at pleasure.
Fifth. In employing in combination any two or more of the appliances 20
above described, for the purpose set forth.
By these improvements the more advantageous use is secured of the
motor fluid, and the quantity of the induced fluid placed under
economical control under the varying conditions of quantity, pressure,
and resistance.

Letters Patent, bearing date the Twenty-fourth day of June, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
5 cessors, give and grant unto me, the said William Oleland, Her special
licence, that I, the said William Cleland, my executors, administrators,
and assigns, or such others as I, the said William Oleland, my executors,
administrators, and 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 JET APPARATUS FOR GIVING MOTION TO FLUIDS," upon the condition
(amongst others) that I, the said William Cleland, my executors or
› administrators, by an instrument in writing under my, or their, or one
of their hands and seals, 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 William Cleland, 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
two Sheets of illustrative Drawings, and to the figures and letters marked
thereon, that is to say :-
The object of this Invention is to provide means whereby when a jet
of elastic fluid used as motive power is caused to act directly on the
fluid to be moved, such jet shall be capable of adjustment so as to act
more advantageously when the quantity of either the moved or motor
fluid is variable or the pressure or resistance varies, and consists—
First. In so arranging a series of induction pipes or mixing nozzles of
different sizes that any of such nozzles can be readily brought into
position to allow of the more efficient action of the motor fluid. The
¡ induction pipes or nozzles may be fitted in a disc arranged so as to be
revolved, or they may be fitted in a cylinder or on a slide, the object in
all cases being to bring the desired one into position.

page_text: into the open air. Eight induction pipes i are hero shown cast with or
secured to the disc j, which diso and pipes when moved around their
central axis by the handle / so as to bring any desired one into position
is steadied by the guiding ring ' and affixed by the pin passing
5 through and entering corresponding apertures in the disc j. When
the diso; and induction pipes i are moved the pin 7 is removed, and the
spindle & and sleeve 6 withdrawn by the wheels and screws e and f.
First Part.-Fig. 4 is a longitudinal vertical section, and Fig. 5 a
vertical transverse section at the line B, B, (Sheet I.) of a modification
of apparatus under the first part of my Invention; here instead of the
induction pipes or mixing nozzles being of different sizes as regards both
length and diameter they are of different sizes as regards diameter only.
The same letters are used to denote like or equivalent parts to those in
Figs. 1, 2, and 3. The induction pipes are eight in number, and they
› are guided and supported at both ends in the cylindrical containing
box h, the spindle of the handle k by which they are made to rotate
being carried or supported at both ends.
First Part.-Fig. 6 is a longitudinal vertical section, and Fig. 7 a
transverse section at the line 0, 0, (Sheet I.) of another modification of
O apparatus under the first part of my Invention. The letters used in
Figs. 1, 2, and 3, are employed to denote the same or equivalent parts
here. The induction pipes or mixing nozzles are made cumulative,
that is to say, each one is made of several short lengths with open
annular spaces between them to receive the moved fluid. These
5 induction pipes or mixing nozzles are of different sizes as regards both
length and diameter, although they might vary as regards diameter only,
and they are revolved by the handle k under my Invention, substantially
as in Figs. 1, 2, and 3, and 4 and 5, above described.
First Part. Fig. 8 is a side view in elevation and section, and.Fig. 9
) a transverse section at D, D, (Sheet II.) of a further modification of
apparatus under the first part of my Invention. Here the steam or motor
fluid is supplied at m and regulated in its flow by the hand wheel and
screw operated spindle n. o is the gas or moved fluid passage, three
movable induction pipes p are here shown of different sizes arranged to
$ be moved opposite o by the screwed spindle and handle q. The dis-
charge from the containing box is through the passage 8,
•

page_text: It will be obvious that the details of parts under the first head of my
Invention may be variously modified and adjusted, so long however as
the apparatus provides for adjustment to the quantity and resistance of the
fluid to be moved or to the quantity and pressure of the motor fluid, such
parts or apparatus would be of and in accordance with my Invention.
Second Part. Fig. 10 is a view in longitudinal section and elevation;
Fig. 11 a front view; and Fig. 12 a transverse section at E, E, (all
Sheet II.) of apparatus constructed with articulated induction pipes
under the second part of my Invention. Two articulations or pieces
marked t are shown; they are arranged to be moved away from the main 1
induction pipe u by the screwed spindles and handles separately; they
might be moved together.

The other parts of the apparatus are similar to those described with
reference to the first part of my Invention.
Third Part.-Figs. 18 and 14 are views separately in longitudinal 1
vertical section and front elevation and section (Sheet II.) of apparatus
under the third part of my Invention. The sliding telescopic and
adjustable projector a³ is moved inwards or outwards by the hand wheel
and screw 6³, and in this modification (as also in Fig. 1 above described)
the said projector and the spindle c' are movable inwards and outwards 2
in relation to the stationary part of the induction pipe d³, and can be
adjusted so as to admit a larger or smaller volume of the motor fluid.
By altering the point of termination of the projector in the stationary
pipe a' the effect can be varied; thus for instance, given a certain
quantity and pressure of motor fluid, if the termination be near the 2
inlet end of the cylindrical part of such an induction pipe, as is figured,
fluid can be moved against a greater resistance than if the termination
be near the outlet end.
Fourth Part. Fig. 15 is a vertical longitudinal section; Fig. 16, a
front view (part in section); and Fig. 17, a back end elevation 30
(Sheet II.) all of apparatus under the fourth part of my Invention ;
here the sliding telescopic portion m* is caused to move over the
stationary portion n', the two together forming a combined adjustable
induction piece. The sliding motion is obtained by the screwed
spindle o' passing through the piece p*. q*, operating handle. A guiding 38
web carrier to ensure easy movement is employed.

page_text: Fifth Part. The combination of any two or more of the above
appliances can be advantageously effected in practice, as will be
apparent.
"
Having now described the nature of my said Invention, and par-
ticularized the same in such manner that others will be enabled to carry
my improvements into practice, I claim, the improvements in jet
apparatus operating and constructed substantially in the manner and for
the purposes set forth.
"
In witness whereof, I, the said William Cleland, have hereunto
set my hand and seal, the Twenty-second day of December, in
the year of our Lord One thousand eight hundred and seventy-
five.
