' GAS WASHER AND SCRUBBER.

SPECIFICATION forming part of Letters Patent No. 545,392, dated August 2'7, 1895.

Application filed April 24, 1895.

To all whom it may cancer-n."

Be it known that I, WILLIAM TRACY, of Leavenworth, in the county of Leavenworth and State of Kansas, have invent-ed certain new and useful Improvements in Gas Washers and Scrubbers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thercon,which form a part of this specification.

My invention relates to the class of vertical gas washers and scrubbers, the gas entering at or near the bottom of the structure and the water entering at the top; and it consists in certain specialties of construction and in combinations which will clearly appear from the description below. The apparatus is also adapted for using it as a washer on one side of it and as a scrubber at its other side, and the casing may be built square-round, or otherwise, as circumstances or location may require.

In the drawings, Figure 1 illustrates a central vertical section of one form of apparatus embodying my invention; Fig. 2, a cross-section on the line A B of Fig. 1; Fig. 3, a top view, enlarged, of one of the diaphragms and its perforated hinged plate; Fig. 4, a central section of the same and'with the hinged plate shown in dotted line as when raised; Fig. 5, a section enlarged and in perspective showing the relative positions of the upper and lower portions of the several diaphragms; Fig. 6, a side view, enlarged, of the lower portion of the diaphragm; and Fig. 7,a top View of the same enlarged.

A indicates the case; B, the gas-inlet; O, the water-inlet; D, the gas-outlet, and E the water-outlet.

lVithin the case I make a number of partitions of special construction, placed one above the other, and each adapted to serve as a water seal. They are each composed of an upper diaphragm F, extending more than half way across the case, as shown, having a down weirdly-projecting flange f, and of a lower diaphragm G, extending from the opposite side of the case and reaching more than half way across it, and having an upwardly-prodcrial No 547,036. (Io model.)

jecting flange g, this flange g reaching, as shown, to a height somewhat higher than the lower edge of the flange f, so that when the lower diaphragm G is filled with water flange f shall dip into the water, thus making a water seal. Every other one of these partitions has its diaphragm G at one side of the case and the remainder at the opposite side, as shown. Each diaphragm F has hinged to its flange atha sealed perforated segmental plate H, whose outer or curved edge rests, as shown,on a suitable support on the case, this plate being in a plane somewhat lower than that of the top edge of the flange g.

I make suitable manholes in the case in front of each section for easy access thereto for the purpose of cleaning, as shown in dotted lines at 'm in Fig. l, and by raising the hinged perforated plates this cleaning of each section can be easily done without removing any part. The number of the diaphragrns may be as many as desired.

A pipe L outside of the case is connected severally with the water-holding diaphragms on one side of the case, and another pipe K similarly connects with the corresponding water-holding diaphragms on the other side of the case, each pipe having suitable valves Z Z, each of these pipes being adapted to discharge as need be inside the case at a point below one of the lowermost diaphragms.

The operation of the apparatus is as fol lows: Water having entered at the inlet 0 to fill successively each of the lower diaphragms or water-chambers G by reason of the overflow of the top one, when filled to the sealingliue, dropping to the next diaphragm G, and so on successively till all are sealed. The gas is now permitted to enter through gasinlet B, and by reason of the water sealing must follow the only course left for it, as indicated by the arrowsthat is, first up and, say, to the right,over the ledge g of the lower diaphragm G, thence downward into the wa ter therein, thence under the ledge f, and upward through the perforated sealed plate H, upon which water may be continually dropping, as shown,fron1 the diaphragm next above it. The gas continuing upward must now turn to the left to enter the water in the second diaphragm, and thence through it and forations D of this diaphragm, and so on successively with each and allof the diaphragms until its final escape through the gas'outlet D.

WVhen in full operation, it will be understood that the entering gas in passing to the first section or diaphragm is carried under the strongest liquornamely, that in the bottom diaphrag1n-and the water entering atthe top being clean the gas in traveling to the top becomes thoroughly washed and cleansed from ammonia and deprived of a good portion of the carbonic acid and sulphureted hydrogen.

By opening all the valves Z on one side of the case the water is allowed to pass out from all the water-holders G at that side and unseal all the partitions at that side, while at the same time the valves on the other side remaining closed the partitions at that side remain sealed, and thereby the apparatus at once becomes a Washer at one side and a scrubber at the other.

The Whole structure is a simple, cheap, and effective washer-scrubber for all small gasworks.

I claim- 1. A gas-scrubber having within its case, a series of horizontal partitions one above the other, each composed of an upper and a lower flanged diaphragm as set forth extending from opposite sides of the case to and beyond its center, the upper one having a perforated plate reaching from its flange to the Wall of the case, and such flange dipping into the lower diaphragm below its highest water line, all substantially as and for the purposes set forth.

2. In a gas-scrubber partition composed of the parts F and G projecting from opposite sides of the case and having the ledgesf' and g respectively the ledge f extending downward below the upper edge of g and forming a seal,a perforated plate hinged near the center of the case to the part F, all substantially as set forth.

3. In combination with the case and with its gas inlet and outlet, the described series of upper diaphragms having each a ledge f to form a seal, the perforated plates and water-chambers, all located alternately at opposite sides of the case, and the pipes Z Z at opposite sides of the case, each of said pipes connecting with said alternate water-chambers, substantially as and for the purposes set forth.

4. In combination with the casing and its described flanged partitions, the upper flange being adapted to dip into Water to make a water seal, the described series of perforated plates each hinged near the center of the case and each constituting a part of a diaphragm, and located alternately at opposite sides of the case and in proximity to the manholes, all substantially as set forth.

5. In combination with the case and its diaphragms, and their ledges g and f, the latter serving to form a seal, the perforated plates, the pipes at opposite sides of the case and each connected to alternate water trays located on opposite sides of the case, and valves in said pipes, and whereby upon opening all the valves in one of said pipes, the apparatus is made to serve as a washer at one side, and as a scrubber at the opposite side, all substantially as set forth.

WILLIAM TRACY.
