VAPOR-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 587,842, dated August 10, 1897.

Application filed October 9, 1395.

To all whom it may concern:

Be it known that I, SAMUEL G. MERRICK, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improve ments in Vapor-Condensers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines or apparatus for condensing fumes, destroying noxious vapors, securing by-products of combustion, vaporization, or distillation, and other like purposes.

The object of the invention is to improve mechanisms heretofore devised for such purposes.

Figure l is a longitudinal section showing the essential parts of a mechanism devised for this purpose; Fig. 2, a cross-section on line so a: of Fig. 1; Fig. 3, a cross-section on line y y of Fig. l.

The drawings are intended to be merely diagrammatic, as illustrating the general features of my device in one form only.

Many modifications are within the spirit of the invention and the claims.

The reference-letter A indicates the box or casing, which should be water-tight at the lower part and preferably air-tight at the upper portion, except the inlet for smoke or gases, which may be of suitable form and location, as at A The casin g should be pitched, painted, lined with glass or porcelain, or otherwise made durable against the attacks of gases or chemicals used in disinfecting or condensing. This box or casing is divided into two parts or chambers K and L by the partition B.

The shaft 0 extends from end to end of the casing, passing through and supported -in suitable stuffing-boxes D D at the ends.

The shaft is driven from pulley E or in any other suitable manner. Around shaft 0 are coiled pipes F F, which are rigid with the shaft, and are supported to move with said shaft by spiders or similar supports G on the shaft.

A diaphragm or disk H may support the tubes F in line with the partition B, and the outside of the tubes may have a collar I'attached, thus forming a bearing for the tubes Serial No. 565,174. (No model.)

at the partition B and cutting off the passage through the cylinderformed bythe coils of tube, so that there is but little circulation of liquid round the coils in backward direction.

The receiving-chamber K and the condensing-chamber L are preferably partly filled with water or other liquid, which may be a chemical reagent of the gases acted on.

The normal height of the liquid in the chambers is such as to cover the coils in the chambers. The flaring months F F of the coiled pipes F F will then take in air or gas as the shaft 0 and its attached coils rotate in proper direction, when the flaring mouths of said pipes are above the liquid-surface, and, carrying the gases under the liquid-surface, will convey it along the coils, compressing and condensing the gases therein, and finally 7o delivering the residuum in compartment L. Much of the gases so treated will be absorbed by the pressure and chemical action of the liquid on the gases in the pipes. The residue and some of the liquid will pass out of the ends F of the pipes during the rotation.

It sometimes becomes desirable to change the level of the liquid in the chambers or compartments K and L. Thus if the liquid in the compartment L has its surface above that in compartment K there will be a greater resistance and the gas will go forward under a greater pressure. If the reverse be the case, then there will be a suction through the pipes, other passages being approximately closed between said chambers.

Let N N represent the cylinders of a pump, which pump may be actuated by eccentricrod '0, connecting to an eccentric P on the shaft 0. This pump, of any suitable kind, communicates with the interior of the chambers K and L by means of pipes S and suitable valves or cocks T. The rotation of shaft 0 then by means of the pn mps connected thereto forces the liquid from chamber K into chamber L, or by reversing the pump the water may be drawn in reverse direction.

U U indicate regulating pipes or passages through the partition B, and by suitable cocks or valves in said passages, preferably controllable-from outside the casing, the comparative height or pressure of liquid or gases in either compartment may be maintained, and by the pump N a rapid circulation may be had.

To still further vary the pressure in the diiterent chambers, and to assist, if necessary or desirable, in drawing in the fumes or gases into chamber K, a fan or blower W may be connected to chamber K. As shown, this fan is inside the chamber and is driven by suitable driving means from shaft C. It will readily be understood that the location may be just outside the chamber and the power maybe otherwise applied. This fan or blower may be used to draw the gases into'the chamber K through suitable openings in the casing and to feed them directly to the coils of the pipe, thus tending to increase the pressure in the chamber K and thereby raise the height of the liquid in the chamber L.

y indicates a passage between the chambers, above the water-line, by which the gases or fumes once passed through the coils may be allowed to return for a second treatment. Preferably this passage should be provided with a check-valve. A pipe or passage Z may be provided to convey away the gas not absorbed or condensed. A pipe or cock U may be used to draw oft liquid.

The mechanism I have described is a development of and improvement on the mechanism patented to Kirk and Ayers, No. 153,173, of July 21, 1874, and, as will be readily understood by a person skilled in the art, will admit of great modifications without essentially departing from, the general idea of the improvement, which is to control the relative height of the liquid in the receiving and condensing chambers of the apparatus and to control the pressures and circulation of both the gases and liquids more perfectly than has been done heretofore.

What I claim is- 1. In a condenser for gases and the like, the receiving-chamber, the condensing-chamber, and a coiled pipe having its inlet in the receiving-chamber and its outlet in the condensing-chamber, means for rotating said coil, a liquid-supply inthe chambers, and means "driving said pump, all combined substantially as described.

3. In a vapor-condenser of the character described, the casing having receiving and condensing chambers separated by a partition, the rotating coiled pipe having one end in each chamber and passing with an ap-- proximately closed joint through said partition, and passages through the partition controlled by suitable valves, all combined substantially as described. 7

4. The condenser having receiving and condensing chambers and the rotating coiled tube having one end in each chamber, and passing through the dividing-partition with an approximately closed joint, the valve-controlled passage through said partition, and the pump communicating with the two chambers, all combined substantially as described.

5. In a vapor-condenser, the combination of the receiving and condensing chambers having a liquid therein, the rotating coiled pipe having one end in each chamber, and the fan in the receiving-chamber operatively connected to the rotating coil, all combined substantially as described.

6. In a vapor-condenser, the combination of the receiving and condensing chambers, the rotating coiled pipe communicating with each, the liquid-supply in said chambers, and a'ci'rculating-pump in one chamber and driven by the coil-drivin g mechanism, all combined substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
