No. 15601.—5th November, 1902.—The Hon. CHARLES
ALGERNON PARSONS, of Heaton Works, Newcastle-on-Tyne,
Northumberland, England, Engineer. Improvements in
condensers working in conjunction with air-pumps.

Claims.—(1.) The use of an ejector or jet pump, operated
by steam, in conjunction with a vacuum pump, in order to
intensify the vacuum produced by the vacuum pump. (2.) In
the evacuation of vessels, the employment of a steam-operated
ejector or jet pump in conjunction with a vacuum pump, the
ejector being situated in the passage which connects the air-
pump with the vessel to be evacuated, whereby the vacuum
produced by the vacuum pump is intensified. (3.) Intensi-
fying the vacuum produced in a condenser by the air or
vapour pump by means of a steam-operated ejector or jet
pump working in conjunction with the air-pump, the ejector
being situated in the passage which connects the air-pump
with the condenser, substantially as described. (4.) In the
system of intensifying the vacuum in a condenser claimed in
claim 3, the employment of an auxiliary condenser between
the ejector and the air-pump, for the purpose described.
(5.) Condenser plant employing an ejector or jet pump
operating in conjunction with the vacuum pump in order to
intensify the vacuum, consisting of a condenser having one
of its ends lower than the other, the lower end being on a
higher level than the vacuum pump with which it is con-
nected, whereby the water of condensation flows by gravity
into this pump, the other end of the condenser being con-
nected with the vacuum pump by way of the steam-operated
jet pump, whereby the work of the jet pump is limited to
the ejection of air and vapour from the condenser to the
vacuum pump, substantially as described. (6.) The im-
proved condenser plant described with reference to Figs. 5
and 6 of the drawings. (7.) A vacuum-intensifier operating
in conjunction with a vacuum pump and comprising an
ejector-box into which the gases and vapours from the vessel
to be evacuated are drawn on their way to the vacuum pump,
the box having within it one or more steam-jets directed
towards the centre of a discharge-passage leading to the
pump, whereby the gases and vapours are assisted in their
progress from the vessel to the vacuum pump and the
vacuum in the vessel is intensified, substantially as described.
(8.) The steam-operated intensifier, as and for the purposes
described with reference to Figs. 1 to 4 of the drawings.
(9.) In the system of vacuum-intensifying claimed in claim 1,
adjustable steam-jets, as described with reference to Figs. 7
and 8 of the drawings. (10.) In the system of vacuum-
intensifying claimed in claim 1, a vacuum-intensifier con-
sisting of a suction-box containing a steam-chest provided
with a nozzle concentric with the discharge-pipe, the chest
having within it a tubular plug for regulating the amount of
opening of the steam-jet, the discharge of air or vapour being
effected through the tubular plug alone or through the plug
and an annular space between the nozzle and the discharge-
pipe, substantially as described. (11.) In the system of
vacuum-intensifying claimed in claim 1, adjustable steam-jets,
as described with reference to Figs. 11 and 12 of the draw-
ings.

which it is transferred to the shaping-mechanism. (2.) The
combination with a set of pickers, of a shaping-mechanism,
means for operating the pickers, and an intermittently
operated conveyor for transferring the tobacco from the
pickers to the shaping-mechanism. (3.) The combination
