Improvements in and relating to Vapour Condensers, and Apparatus
for Destroying Noxious Fumes, Recovering By-products from
Distillation, and like purposes.
We, SAMUEL GUEST MERRICK, Gentleman, of 536 and 538 Philadelphia Bourse, in
the City and County of Philadelphia and State of Pennsylvania, United States of
America, and HENRY LUCIUS WASHBURN, Lawyer, of 280 St. Nicholas Avenue, in the
City, County and State of New York, United States of America, do hereby declare
the nature of this invention to be as follows:-
This invention has relation to machines for condensing smoke, gases, noxious fumes,
and the like, and to certain improvements in the construction thereof.
In a former Patent, dated December 31st, 1895, No. 25,001, we described a machine
wherein a tube, or tubes, was wound in spiral coils about a rotating shaft, said tube or
tubes having a mouth piece extending outside the general line of the spiral, and above
the level of a liquid covering the body of the coils, the ends of the coils being in.
separate compartments of a casing.
In the present invention we have a casing with two compartments, one the receiving
and the other the condensing or delivery chamber. A shaft, or other means, for
driving, extends through both compartments of the chamber. A coiled tube surrounds
this shaft and is caused to rotate by it. The coils of this tube decrease in diameter
toward the delivery end, or that end of the coiled tube is at a lower level, so that
smoke or gases drawn into the inlet end of the coil above the surface of the liquid will
be carried further under the surface level of the liquid as it progresses toward the
delivery end of the coils, being thus under greater pressure. When the mouth of the
coiled pipe moves under the level of the liquid in the casing, it takes in liquid, thus
causing the gas, smoke, or vapor, and the liquid from the receiving end to pass
toward the delivery end of the coiled tube. The coiled tube is preferably covered for
most of its length by a sheet metal casing, which is either the frustum of a cone or is
inclined from the horizontal, and a partition divides the compartments and fits pretty
closely to this casing.
A modification of this construction is made by coiling a metallic ribbon or ribbons
in spirals about a shaft and inside a casing which is the frustum of a cone. One end
of the conic frustum is in the receiving and the other in the delivery chamber or com-
partment of the casing. The ends of the frustum are in the form of inclined scoops,
which draw in the gases and liquid as the frustum rotates, and expel them, with the
gas condensed or absorbed, from the other end of the frustum, into the other
compartment.
Suitable means are provided for regulating the height of the liquid in the compart-
ments, and for conveying the liquid, and smoke, or gases, to the receiving from the
delivery chambers.

We, SAMUEL GUEST MERRICK, Gentleman, of 536 and 538 Philadelphia Bourse, in
the City and County of Philadelphia and State of Pennsylvania, United States of
America and HENRY LUCIUS WASHBURN, Lawyer, of 280 St. Nicholas Avenue, in the
City, County and State of New York, United States of America, do hereby declare
the nature of this invention to be as follows:-
Figure 1 is a longitudinal section and partial elevation of the machine in its
preferred form,
Figure 2 is a cross-section of the conveyor,
Figure 3 is a broken elevation of the conveyor,
Figure 4 is a longitudinal section showing another form of our invention with the
conveyor partly in section:
The main chamber A, receives the smoke or gases for condensation from any
source, as by pipe B. The conveyor C, consists of a frusto-conical metallic casing
having spiral vanes or wings D, D, inside, said wings extending from the axis to the
casing. The conveyor is supported by a shaft E, which passes through both chambers,
in suitable bearings or stuffing boxes F, and the shaft and conveyor may be rotated
by means of power applied to pulley G, or otherwise.
The exit chamber or chamber of condensed gases A' is separated from chamber A
by a partition H, which fits down about the shell of the conveyor to a level below the
water line W. An exit pipe B¹, may lead away the small residuum of uncondensed
gases to a stack, or other suitable place.
The two chambers are filled with water or other liquid which may be a reagent of
the gas to be condensed, to a level above the shaft E. Then by rapidly rotating the
conveyor, the gas, smoke, or air, in the chamber A, will be conveyed by the spiral
vanes along the passages between said vanes, the scoop-like ends of these passages
taking in gas when above the water line, and taking in water or liquid when below the
water line, and conveying both the air and liquid in jets or gouts as it were, to the
chamber A', in which the liquid has a tendency to rise above the level of liquid in
chamber A. From chamber A¹ the liquid has a tendency to run back under
partition H. The pressure of the liquid on the air within the conveyor is determined
by the height of the water in the respective chambers; but the water must not entirely
cover the upper portion of the conveyor in the chamber A, or there would be no gas
received into the conveyor.
The conical form of the conveyor causes a gradual increase of pressure as the
gases move along.
In Figure 4 there is shown a casing C of similar form to the casing hereinbefore
described. This casing is supported on shaft E, and the general arrangement of
inlet and compression chambers is similar to that already described. The partition H',
fits pretty closely to the casing, but has openings for the passage of liquids and of
gases, which openings are controlled by valves from outside the chambers.
The casing C' has coiled pipes D¹ therein, which pipes convey the alternate jets
of smoke or gas and of liquid from chamber A³ to chamber A. In a general way.
the operation of the machine, is the same as that shown in Figure 1, the main
difference being in the construction of the conveyor.

page_text: Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed we declare that what we claim is :
1. The combination of parts constituting the machine for compressing or con-
densing air and gases, having a receiving chamber, a compressing chamber, and
the rotary frusto-conical conveyor having one end in each chamber, and the means
for rotating said conveyor.
2. The frusto-conical conveyor in its novel relation to the condensing chambers,
Eubstantially as described.
3. The frusto-conical conveyor and means for driving the same, the chambers and
partition between same, and the coiled pipe inside the casing of the frusto-conical
conveyor.
