SMOKE-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 521,054, dated June 5, 1894.

7 Application filed June 21,1893. Serial No. 478,314. '(No modeh) &c., may be stopped to avoid the emission of heavy products usually discharged in smoke and the Invention consists in the novel constructions, combinations, and arrangement of parts as will be hereinafter described and pointed out in the claims.

In the drawings Figure 1 is a top plan V ew of an apparatus embodying my invention. Fig. 2 is a cross section on about line 2 -2 of Fig. 1. Fig. 3 is a section on about l ne 3-3 Figs. 1 and 2 at right angles to the line of Fig 2, and Fig. 4. is a detail view.

In carrying out my invention I provide a plpe A leading from the smoke chimney or other smoke discharge of the furnace, a receiving chamber B into which the smoke is discharged, a blower O or the like being em nozzles serve to divide up the smoke discharged so that no great volume is discharged at one point. This is desirable to avoid the formation of large bubbles in the water of the tank. The tubes of the nozzles lead into the tank E which is covered and partly filled with water and the nozzle discharges open below the surface of said water so that the smoke is dlscharged below the said surface and directly Into the water so that the latter will catch all soot, sparks and similar solid matter. Astop plate F is arranged in the tank above the nozzles and resting either upon or slightly below the surface of the water its function being to break any bubbles that may rise from the nozzles and so prevent the sparks, 850., rising from the water by the bursting of said bubbles at the surface. The tank may be filled by a pipe G or in other suitable manner and- I prefer to provide an outlet pipe g to preserve the level at the desired point. At one end of the tank is a soot outlet or discharge H while a fan or blower I is arranged to discharge its blast into the tank at 2' at the end opposite the discharge H, the inlet 41 and outlet H being arranged at about the water level so that the blast will tend to drive off the soot and similar accumulations upon the water.

In operation the fans may be driven by electricity or other power so that when the fire is started in the furnace the first smoke may be treated as well as that made after the fire has gotten well under way.

The receiving chamber B has at one end a door B, through which access may be had to I the said chamber for the purpose of cleaning out the cinders, &c., which will accumulate therein. The nozzle tubes connect with the chamber about half way between its top and bottom, leaving a receptacle in the bottom of said chamber for such cinders as may accumulate therein.

In practice I prefer to employ at C a planing mill fan the smoke to go in the side of the fan. I also prefer to provide in the pipe A which leads from the chimney an opening A and slide gate A to regulate the draft in the furnace also to admit cold air to check the blaze.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In an apparatus substantially as described the combination of the water tank,

the collecting chamber the nozzles leading ICO soot &c., and blast devices discharging into the said tank such devices being arranged relative to said outlet substantially as described and adapted to force the soot 85c. therefrom all substantially as set forth.

4. In an apparatus substantially as described, the combination with the tank having an outlet at or about its water level, and a blast inlet opposite said outlet, blast devices communicating with said inlet and devices conducting the smoke &c. to such tank all substantially as and for the purposes set forth.

5. In a smoke arrester the combination of the receiving chamber, having the nozzles, the water tank into which said nozzles discharge, said tank having a blast inlet and an outlet opposite the same, the tube or flue leading to WILLIAM P. SlI ANK.
