SMOKE-WASHER.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed March 1, 1918. Serial No. 219,929.

To all whom it may concern:

Be it known that I, RICHARD J JOHNSON, a citizen of the United States, residing at Lake Benton, in the county of Lincoln and State of Minnesota, have invented certain new and useful Improvements in Smoke- )Vashers, of which the following is a specification.

This invention relates to smoke washers which may be used in connection with any source of smoke supply, such as asmoke stack.

The object of the invention is to provide a simple and efiicient apparatus of this character which will thoroughly mix'and dissolve the products of combustion in water and then discharge the water into a sewer or other suitable place of deposit where it will be harmless.

Another object is to provide an improved mixer or washer of this character whereby the smoke and other combustion products discharged thereinto will be effectively agitated and commingled with water contained therein.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter clescribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings 2- Figure 1 represents a vertical section of a washer constructed in accordance with this invention.

Fig. 2 is a horizontal section taken 011 the line 2-2 of Fig. 1, and

Fig. 3 is a similar view 33 of Fig. 1.

In the'embodiment illustrated, the apparatus constituting this invention may be connected with any source of smoke supply (not shown), such as a boiler or other furnace smoke stack.

The apparatus constituting this invention comprises a closed casing 1 having a discharge outlet l at its upper end which is designed to be connected with a pipe (not shown), which conveys the water and the unaffected gases discharged through the easing to a sewer or other suitable place of deposit.

taken on the line A pipe 2 enters the washer or mixing casing 1 through the top thereof and extends to a point near its bottom where it is provided with lateral oppositely disposed extensions 8 and 4 having upturned mouths 5 through which the products of combustion entering through pipe 2 are designed to be discharged.

Revolubly mounted on the end of the pipe 2 which is disposed within the mixer is an agitator in the form of a plurality of reticulated vanes 6 which radiate through collars 7 and 8 revolubly mounted on said pipe end 2. Any desired number of these vanes 6 may be employed, four being preferably used, and the mouths 5 of the pipe extensions 3 and 4 are disposed adjacent the lower ends of said vanes and are designed to discharge their contents in the path of the vanes so that the revolutions thereof will operate to thoroughly commingle the products so discharged with the water contained in the mixer.

A bevel gear 9 is fixed to the collar 7 and meshes with a bevel pinion 11 carried by a shaft 10 which extends laterally through one side wall of casing l as shown clearly in Fig. 3 and by means of which motion is imparted to the mixing vanes. Motion is imparted to this shaft 10 by any suitable means (not shown).

A water supply pipe 12 enters the casing 1 at the lower end thereof and is connected at its other end with any suitable source of supply (not shown), so that water may be continuously supplied to the casing 1, en-

tering at the bottom thereof and overflowing at the top through pipe 1.

In the operation of this apparatus, motion being imparted to shaft 10 by a source of power (not shown), will cause the vanes 6 to rotate within casing 1 and the products of combustion entering through pipe 2 will be thoroughly commingled by the revolutions of said vanes with the water in the casing 1. WVhen these products of combustion have been thoroughly commingled and dissolved in the water of the mixer they pass out with the water through pipe 1 to a suitable place of deposit.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have an outlet at its upper end,

' combustion thereto, said pipe describedvthe principle of operation of the understood that against which the contents of said pipe are I discharged. 7

2. In a smoke washer, a closed water containing mixing chamber having an inlet at its lower end and an outlet at its upper'end,

a pipe extending into said chamber through Copies of this. patent may be obtained for five cents each, by addressingthe the best embodiment illustrative and the top to a point near its bottom, said pipe having lateral extensions provided with upturned mouths, and'a plurality of agitator vanes revolubly mounted on said pipe above said mouths and against which the contents of said pipe are discharged,

3. An apparatus of the class described including aclosedcasing having an outlet pipe at its upper end and adapted to contain a washing fluid, a smoke pipe extending'into said casing through the top thereof and provided at its lower end with laterally extending branch pipes having upturned mouths at their free ends, ed to rotate on said pipe above said mouths, and means for actuating said agitators.

In testimony whereof I aflix my signa ture in presence of two witnesses.
