JOHN ALTENHOFEN, OF RIQHLAND, IOWA.

SMOKE-WASHER.

Application filed March 12, 1909.

To all whom it may concern:

Be it known that I, JOHN ALTENHOFEN, a citizen of the United States, residing at tichland, in the county of Keokuk and State of Iowa, have invented a new and useful Smoke-Washer, of which the following is a specification.

The objects of the invention are, generally, the provision, in a merchantable form, of a device of the class above mentioned, which shall be inexpensive to manufacture, facile in operation and devoid of complicated parts; specifically, the provision of a series of water-supply pipes adapted to be assembled with a smoke-stack whereby the contents of the said pipes may be distributed within the said stack, effectively to cleanse the smoke therein; and of novel means for effecting the distribution of the water with in the stack as it flows from the supply pipes; other and further objects being made manifest hereinafter as the description of the invention progresses.

The invention consists in the novel construction and arrangement of parts hereinployed to denote corresponding parts throughout the several figures of the drawmgs.

In the accompanying drawings :-Figure 1 shows my invention in side elevation; Fig. 2 is a vertical transverse section, parts being shown in elevation; Fig. 3 is a transverse section upon the line AB of Fig. 2.

In carrying out my invention, I provide, primarily, a stack 1, which may be of any form. In the present instance it is shown as circular in transverse section and flared at its lower extremity to form a pit 2. The upper extremity of the stack 1 is flared as denoted by the numeral 3, and above this flared portion the stack may terminate in any suitable manner not inconsistent with the removal of the sleeve 7, hereinafter de- Speoification of Letters Patent.

Serial No. 482,988.

scribed, from the top of the stack. Above the pit 2 a pipe 9 pierces the wall of the stack 1 to provide a suitable inlet, whereby smoke may pass into the said stack.

Disposed upon the exterior of the stack 1 is a water supply pipe l, which may be attached to the pit 2 by means of a bracket 5. The upper extremity of the pipe 4: is laterally bent as denoted by the numeral 6 and passes through the wall of the stack 1 in the flaring portion 3 thereof. Mounted 1n the interior of the stack 1 at the upper end thereof is a sleeve 7. This sleeve 7 is of slightly larger diameter exteriorly, than the interior diameter of the stack 1, so that when the sleeve is pushed downward in the flaring portion 3 of the stack, an annular trough 14: will be formed between the sleeve 7 and the wall of the flaring portion 3 of the stack. The sleeve 7 is provided with a series of apertures 8 extending entirely around its periphery. I further provide, in carrying out my invention, an inner water supply pipe 10, designed to be mounted, preferably axially, in the stack 1. The pipe 10 is retained in place by means of radially extending brackets 11, which form braces between the walls of the pipe 10 and the walls of the stack 1. The upper end of the inner supply pipe 10 is provided with a baffle-plate 12. This bafl'le-plate 12 may be of any form. In the form shown in the drawings the baffle-plate is dished or upwardly convexed. The water supply pipes 4 and 10 may be connected with a hydraulic main, and the device operated by means of an urban water supply system, or, if desired, pumps of any approved type may be provided for the flushing of the device.

In practical operation, supposing that the device is assembled as shown in Fig. 2, the water which passes upward through the pipe l will enter the annular trough 14 which is formed by the sleeve 7 and the portion 3 of the stack, and, passing inward through the apertures 8 in the sleeve, will trickle down the inner wall of the stack 1, and also be projected in a plurality of separate streams toward the center of the stack 1. The water which passes upward through the pipe 10, passing out of the said pipe 10 at its upper extremity, will impinge against the baffleplate 12, which, owing to its peculiar form, will deflect outward and downward the major portion of the liquid which passes out of the pipe 10. A portion however of the contents of the pipe 10 will trickle down its exterior surface. 7

It will be seen that with the foregoing device, the smoke which passes into the stack through the pipe 9 will pass upward between two concentric cylindrical walls, each of which is covered witha coating of falling water, and that the space between these two walls will be saturated with falling spray. The smoke when it finally leaves the stack at its upper end will be thoroughly cleansed from particles of carbon and other deleterious matter, and, whena boiler is equipped with a stack constructed in accordance with 'myinvent'ion soft coal may be burned, even in the most densely populated localities.

12 maybe used alone, or in connection with the supply pipe 4, the baffle-plate being removed. Likewise, the supply pipe 4 andthe sleeve 7 may be employed to saturate the airin the interior of the stack without turn ing'on the water How in the supply pipe '10. However, the device as shown in Fig. 2 works tobest advantage whenboth'of'the supply pipes land '10 are filled with running water.

Any foreign matter which may be carried upward through the pipe and find lodgment within the trough '14 between the apertures 8 may readily be removed'therefrom by raising the sleeve 7 in the stack 1, allowing such'foreign matter to drop downward into the'pit. When desired, the foreign matter washed from the smoke may be shoveled from the pit in a compact and viscous form.

It will be seen that the foregoing device, although simple in construction and easily manufactured by any skilled ironworker, furnishes a means whereby smoke may the upper end of thestack being so constructed that the sleeve may be lifted out of I the stack at will, the sleeve being perforated If desired, the pipe 10 and the bathe-plate circumferentially and arranged to engage the lower end of the flaring portion of the stack in wedging relation to form a trough between the sleeve andthe flaring portion of the stack; a pipe axially mounted in the stack; and a baffle-plate assembled with the upper extremity of the pipe and arranged to deflect the contents of the pipe downwardly to contact with the jets proceeding from the perforations in the sleeve; and means for simultaneously supplying a liquid to the trough and to the pipe.

In testimony that I claim the foregoing as my own, I'have hereto afiiXed my signature in the presence of two witnesses.

JOHN ALTENHOFEN.
