FREDERICK JONES, trading as George Jones, of Birmingham, in the County of
Warwick, Ironfounder and Machinist. "IMPROVEMENTS IN APPARATUS FOR
RAISING AND FORCING LIQUIDS, FOR EXHAUSTING GAS, FOR BLOWING AIR, AND
FOR MEASURING LIQUIDS."
My Invention consists of the improvements herein-after described in apparatus
for raising and forcing liquids, for exhausting gas, for blowing air, and for measuring
liquids, by which improvements the said apparatus is rendered very simple in con-
struction, and efficient in use.
In arranging the parts of the said apparatus according to my Invention, I construct
a closed oblong chamber with parallel sides and semi-cylindrical ends. Across this
chamber, and working in bearings in the parallel sides of the chamber, two axes are
situated. These axes are respectively concentric with the semi-cylindrical ends of
the chamber. Upon these axes a series of radial equidistant leaves or vanes is
situated, the leaves of one axis gearing or engaging with those on the other, the two
sets of leaves or vanes resembling two pinions, and engaging with each other in the
same way as pinions or toothed wheels. The ends of these sets of leaves work
tightly against the parallel sides of the chamber, and their summits work tightly
against the semi-cylindrical ends of the chamber. The leaves, as those on one axis
engage with those on the other, fit upon each other so closely as to form a practically
air and water tight junction. The chamber is furnished with two pipes at opposite
points, the said pipes opening into the chamber midway between its two ends
When the apparatus is used for raising and forcing liquids, one of the axes is
provided with a winch, pulley, or other appliance, by which rotatory motion can be
given to it. The leaves carried by that axis, by their gearing with the leaves carried
by the other axis, communicate to the latter rotatory motion in an opposite direction.
By turning the axis provided with the winch or pulley, an exhaust is produced
in one of the pipes, and pressure in the other pipe, a current of the liquid being
produced through the apparatus in the direction in which the engaged leaves on the
Price 2d1

forward on the other side By reversing the motion of the rotation of the axes the
direction of the stream is changed.
If the exhaust side of the apparatus open into the atmosphere, a current or blast
of air is produced by the action of the apparatus, which current or blast may be
used for urging combustion in furnaces and for other purposes.
The apparatus may also be conveniently used for exhausting gas, that is, trans-
ferring gas from the retorts in which it is generated to the part of the gas making
apparatus in which it is next received, so as to relieve the retorts from the pressure
to which they would otherwise be exposed.
By passing water or other liquid under pressure through the apparatus, the axes
are made to rotate, and by attaching registering mechanism to one of the axes, the
number of rotations is recorded, and the apparatus is thus converted into a water or
liquid meter.
A valve may be fixed in the ingress or egress pipe, or in both, to prevent the
return of the liquid or gas.
