JOSEPH COUGNET and AUGUSTE PIERRE POTEL, both of Brussels, in the Kingdoin
of Belgium, Civil Engineers. "NEW OR IMPROVED APPARATUS FOR INJECTING,
EXHAUSTING, AND FORCING FLUIDS, WHICH APPARATUS IS ALSO APPLICABLE FOR
OTHER PURPOSES."
Our Invention relates to apparatus for injecting, exhausting, and forcing fluids'
the said apparatus being applicable as an injector, a pump, an elevator, and for
other purposes.
Our improved apparatus consists of a pipe or tube, the hole or opening through
which is of square or rectangular section at each end, and the sides taper or narrow
inwards from the ends or near the ends of the said pipe or tube, so that at a part
of the length of the said tube the hole in section forms a parallelogram, the lengthı
and breadth of which are smaller than the corresponding sides of the square or
rectangle aforesaid. Thus longitudinal sections of the said pipe or tube taken at
right angles to each other would show the said hole to be somewhat similar in
form to two inverted Vs joined together at or near their smaller ends, or two V
shaped chambers (herein-after called the upper and lower tube chambers) opening
into each other at their smaller ends. To one end of the said pipe or tube is affixed
a funnel or tubular mouth-piece of rectangular section which projects into the said
pipe or tube by a tapering nose. The inner part of the said funnel or mouth-piece
is divided into two branches by a central guide plate so disposed and shaped that the
fluid under pressure entering the said mouth-piece will be divided into two currents,
which after leaving the nose will unite in that part of the pipe or tube which is of
smaller section. In section the said funnel or mouth-piece resembles somewhat the
letter W.
In the side of the upper chamber of the pipe or tube is an aperture fitted with a
suitable pipe for the inlet to the apparatus of the fluid or substance to be operated
on; and in the side of the lower chamber of the said pipe or tube is a hole or
aperture provided with a suitable cock or tap through which the apparatus may be
emptied.

page_text: The action of the apparatus is as follows:-The apparatus having been set up in
position, the steam or fluid under pressure used as a motive power is admitted
through the funnel or mouth-piece herein-before described, and passes into the body
of the pipe or tube in two jets, which, uniting within the said pipe or tube, create
a vacuum which draws in from the branch pipe herein-before described the fluid or
other matter to be operated on, and the said fluid or other matter passing through
the apparatus is projected or forced out in a continuous jet by the force of impulsion
within the apparatus.
When the said apparatus is to be used for blowing purposes or forcing air or gas
for promoting the combustion of fuel, drying, ventilating, or other like purposes, we
mount two or more than two of the rectangular funnels of tubular mouth-pieces
herein-before described, one above the other, or one before the other, the branches
of one of the said mouth-pieces opening into the branches of the mouth-piece
immediately below or before it, which latter branches are made rather larger than
the former ones. The said funnels or mouth-pieces may be mounted on a suitable
frame, or may be carried by vertical or other guide rods provided with means for
adjusting the position of each of the said funnels or mouth-pieces as required.
In some cases we construct the apparatus of circular shape having the form of
two inverted cones joined together, the mouth-piece consisting of an annular pipe
mounted between the centre and-sides of the apparatus, the motive fluid passes in
through the said annular pipe and draws in the fluid or matter to be operated on
through the centre part of the apparatus, and through the space between the said
annular pipe and the sides of the apparatus.
