JOHN BUTLER, OF ELLSWORTH, MINNESOTA.

SMOKE PURIFIER AND CONSUMER.

SPECIFICATION forming part of Letters Patent No. 494,522, dated March 28, 1893.

Application filed January l2. 1893. SerialNo. 458.156. (No model.)

To all whom. t may concern.-

Be it known that I, JOHN BUTLER, a citizen ot' the United States, residing at Ellsworth, in the county of Nobles and State of Minnesota, have invented certain new and useful Improvements in Smoke Purifiers and Consumers, of which the following is a specification.

The subject of the present invention is an apparatus, designed to be associated with a furnace of any construction, which apparatus is adapted to exhaust the products of combustion from the furnace and dispose of them either by returning them directly to the cornbustion chamber, or else by forcing them beneath the surface of abody of liquid by which some of them are arrested and through which the balance rise, freed from impurities, after which they may be either allowed to escape into the atmosphere, or else returned to the combustion chamber.

The invention consists in certain features of novelty that are particularly pointed out in the claims hereinafter, and in order that it may be fully understood, I will describe it with reference to the accompanying drawings which are made a part hereof and in which- Figure 1, is a vertical longitudinal section of a boiler and furnace of familiar construction and a sectional elevation of the improved smoke purifier and consumer in its preferred form. Fig. 2 is a plan view of the exhaust apparatus shown in Fig. l. Fig. 3, is a vertical transverse section of the fire-box on the line 3-3.

A represents the fire-box, B the grate, C the bridge-wall, D the boiler, E and F smoke passages at the ends of the boiler, G a horizontal partition dividing the passage E into two parts, and H the smoke pipe communicating with the upper part of said passage E. All of these parts may beV of any desired construction, the construction shown in the drawings being selected at random and without any intention that the invention shall be considered as limited thereto.

One of the essential features of the invention is an apparatus for creating a suction in one of the smoke passages and thereby producing a forced draft through the furnace, but I desire to have it understood that the invention is not limited to an apparatus, for this purpose, of any particular construction. On

the contrary, said invention comprehends any suitable apparatus. In the drawings I have shown this apparatus as consisting of a pump having double cylinders 1,1 and reciprocable suitable fittings with a pipe N, whose connec-f-,

tions are described farther on.

In the forms of the invention shown by Fig. I, two branch pipes N and N2 lead off from the pipe N. The branch N is provided with a hand-valve 'n' and the branch N2 is provided with a hand-valve n2. In the preferred form of the invention the branch N enters an airtight tank O, its end communicating with the interior of the tank near the bottom thereof. The branch N2 extends to the fire-box where it is again branched, its two branches N21L terminating above the grate and on opposite sides of the fire-box, so that they discharge in opposite directions across the fire-box. The discharge end of each of these branches is located in the inner end of a iiue a, the outer end of which is in open communication with the external atmosphere, as shown by dotted lines in Fig. l. v

Pis a pipe having a hand-valve p and communicating at one end with the upper portion of the tank O and at the other with the branch pipe N2, between the hand-valve n2 and the fire-box.

Q is a pipe having a hand-valve q and communicating at one end with the upper part of the tank O and at the other end with the If the valve a is closed and the f IOO other hand, the valves n2 and q are closedand the valves n and p are open, the products of combustion will be forced into the tank O, below the surface of the body of Water or other liquid contained therein. Some of the said products will be arrested by the liquid and the balance will rise through the liquid, by reason of their less specific gravity, and. will pass through pipe P into the pipe N2 and thence to the fire-box, as already described. Again, if the valves n2 and p be closed and the valves fa and q open, the products of combustion will be forced beneath the surface of the liquid as before, andthose that rise through said liquid, freed from impurities, will pass through pipe O into the smoke-pipe H, above the damper h, and thence olf.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a furnace, of an exhaust apparatus, means connecting its induction port with one of the smoke-fines, the pipe N communicating with its educton port, the closed reservoir O having a body of liquid therein, the branch pipe N having valve n and communicating with the interior of the reservoir below the surface of the liquid therein, the branch pipe N2having the valve n2, and communicating with the combustion chamber, and the pipel? having valve p and cornmuni eatin g at one end with the reservoir, above the 'surface of the liquid therein and at the other with the branch pipe N2 between the valve n2 and the combustion chamber, substantially as set forth.

2. The combination with a furnace, of an exhaust apparatus, means connecting its induction port with one of the smoke iiues of the furnace, the pipe N communicating with its eduction port, the closed reservoir O having a body of liquid therein, the branch pipe N having Valve n and communicating with the interior of the reservoir below the surface of the liquid therein, the branch pipe N2 having valve n2 and communicating with the combustion chamber, the pipe P having valve p and communicating at one end with the reservoir above the surface of the liquid therein and at the other with the branch pipe N2 between the valve 'n2 and the combustion chamber, and the pipo Q having valve q and co1n municating at one end with the reservoir above the surface of the water therein, and at the other with the atmosphere, substantially as set forth.
