Year: 1878

page_text: LETTERS PATENT to William Seddon Sutherland, of Birmingham, in the County
of Warwick, Engineer, for the Invention of "IMPROVEMENTS IN MEANS
AND APPARATUS FOR MOVING AND COMPRESSING GASES AND FLUIDS."
PROVISIONAL SPECIFICATION left by the said William Seddon Sutherland
at the Office of the Commissioners of Patents on the 20th August 1878.
WILLIAM SEDDON SUTHERLAND, of Birmingham, in the County of Warwick,
Engineer. "IMPROVEMENTS IN MEANS AND APPARATUS FOR MOVING AND COM-
PRESSING GASES AND FLUIDS."
The object of this Invention is to provide means and apparatus for rapidly and
economically moving and compressing gases and fluids by means of the direct
application of steam or elastic fluid.
For the above purpose I so admit steam intermittently into a pipe, tube, or way
through which the gas or fluid is to be moved, that the said steam or elastic fluid
shall fill the said pipe, tube, or way so as to form discs or pistons, which shall
travel forward in the required direction and drive the gases or fluid before
them.
In order to ensure that the steam or elastic fluid admitted intermittently to the
pipe, tube, or way shall form a disc or piston which shall completely fill the tube
in cross section, I arrange or incline the port so that the steam or elastic fluid
shall issue therefrom in a diverging or converging direction, or both, according
Prins Sil

page_text: as the port is central, annular, or around the external surface of the pipe, tubs,
or way.
I construct or fit the air or gas mover or compresser with a rotary valve, actuated
and caused to revolve by the emission of the steam, say, against vanes, so as to
open and close the port and cause the steam to issue intermittently into the
tube.
-
If desired the valve or valves opening and closing the port may be operated in
any desired manner.
I prefer that the port should consist of an annular series of holes corresponding
to similar holes in the valve.

PRESSING GASES AND FLUIDS."
The object of this Invention is to provide means and apparatus for rapidly and
economically moving and compressing gases and fluids by means of the direct
application of steam or elastic fluid.
For the above purpose I so admit steam intermittently into a pipe, tube, or way,
through which the gas or fluid is to be moved, that the said steam or elastic fluid
shall fill the said pipe, tube, or way with discs or pistons thereof, and travel forward
in the required direction, and drive or suck the gases or fluid before or after
them.
In order to ensure that the steam or clastic fluid admitted intermittently to the.
pipe, tube, or way shall form a disc or piston, which shall completely fill the tube in/
cross section, I arrange or incline the port so that the steam or elastic fluid shall
issue therefrom in a diverging or converging direction, or both, according as the
port is central, annular, or around the external surface of the pipe, tube, or way.
I construct or fit the air or gas mover or compresser with a rotary valve actuated
and caused to revolve by the emission of the steam, say, against vanes, so as to
open and close the port, and cause the steam to issue intermittently into the
tube.
If desired the valve or valves opening and closing the port may be operated in
any desired manner.
I prefer that the port should consist of an annular series of holes corresponding
to similar holes in the valve.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a sectional elevation and Fig. 2 a plan view of apparatus for moving or
forcing fluids constructed under my Invention.
1, pipe or way through which the fluids are to be drawn or forced; 2, steam pipe;
3, annular passage. The steam passes from the annular passage 3 through openings
so as to impinge tangentially on the vanes 4 of the valve 5, and give rotary motion
thereto. The valve 5 has openings 6 corresponding with openings in the port 8, so
that the steam during the rotation of the valve passes into the said port 8 inter-
mittently; 9, valve seat.
The valve and seat may be coned, and means of adjustment provided for keeping
them in close contact.
The valve may be caused to rotate by gearing if desired.
The port 8 is so made as to cause the issuing jets to converge towards the centre
of the pipe and form plugs or pistons, between which the fluid is moved.
Figs. 3 and 4 are vertical sections, and Fig. 5 is a sectional plan of a modification
of apparatus constructed under my Invention.
Here the valve seat 12 has a narrow opening 13 around its circumference. The
band 14 of steel or iron carried on the brackets 15 acts as the valve. The said
band has its two ends secured to the studs 16, preferably bearing on rollers 17.
The rod 18, which receives a reciprocating motion from the piston 19, is fitted at
its ends with cams or wipers 20, which act on the studs 16 so as to cause the band
forming the valve to open and close.
Motion is given to the piston by fluid controlled in any ordinary way.
Other means may be employed if desired to give motion to the rod 18.

page_text: In some cases springs may be employed for keeping the valve 14 to the valve
face.
In Fig. 6 the annular valve 23 is caused to lift intermittently by the action of
the steam on the annular flexible box 25; 26, pipe opening into the interior of the
said box 25. Steam is allowed to act intermittently on the interior of the box 25
by means of a valve operated in any desired way, thus allowing the steam in the
annular way 3 to lift the valve 23 intermittently and pass into the port 8.
Figs. 7 shows a method of controlling the motion of the valve by means of
electricity.
27 is the valve, which is kept down to its seat by the action of magnetism
generated by the coils 28, 29. The steam is allowed to raise the valve 27 by
reason of the interrupted current passing from the commutator 30.
It will be evident that a great number of modifications of apparatus may be made
under my Invention, and that air or other suitable fluid may be used in place of
steam.
Having now described the nature of the said Invention so that others may be
enabled to carry my improvements into effect, I claim;-
First. Admitting fluid intermittently into a pipe or tube, substantially in the
manner and for the purposes set forth.
Second. Admitting fluid intermittently into a pipe or tube by means of a valve
or valves actuated substantially as set forth.
Third. The apparatus or appliances substantially as described, and illustrated by
Figs. 1, 2, 3, 4, 5, 6, and 7, for the purposes set forth.
In witness whereof, I, the said William Seddon Sutherland, have hereunto
set my hand and seal, the Eighteenth day of February, in the year of our
Lord One thousand eight hundred and seventy-nine.
