' SHEETS-SHEET s l-Be;itlncnvhwtlratEGEORGE Monnv, a subject ofl theitliing'rofiGreat Britain, residing at Robinson-,rfin'-the"county of Juab and State of Utahg?.have'invent'ed.new and useful 1mprovernentsf Sinol'ie-Purifiers, of which the following isra specification. Y: VMyiinventioii relates to a pparatusfor treating and purifying smoke and more particularly smoke'fromasinelting furnaces. y

".A's risw'ell hmoivnwthe smoke and fumes given oflfromfsmelting furnaces often contain "sulfur'ous :and f 'other obnoxious gases, which if allowed to escape into the air have uri'ous:effecty upon surrounding vegetation. f Mineral matter insuspension isoften carriedfsoverwiththe productsv of combustion'from-smeltingfurnaces and itis often desirabletoconde'nse and collect -such vaporized or finely divided-material.

.lNithetheabove objects in view myinvention consists irr.the..,aarrangement .and constructiomhereinafter: described and shown in the accompanying drawings, in which- Figure 1 is a side elevation ofmy complete apparatus. Fig.'2 isa sectional view of a fragment of the flue, and, Fig. 3 is a vertical central section on an enlarged scale through the smoke receiver and associated parts.

Referringto the drawings in detail, 1 represents a flue constructed preferably of rectangular section and of sheet metal and sup-n ported on foundations 2 in a slightly inclined position, Connected with the upper end of this flue is a pipe '5` for supplying water thereto, and at the opposite end is a water discharge spout 4 (see Fig. 3). The flue 1 is surmounted at' its upper end by a stack 6 of.

usual construction. At its lower end theiiue l connects with the receiver 8 and from the receiver 8 extends a iiue 7 by which products of combustion enter the apparatus. Below the receiver 8 and arranged under the discharge spout 4 is disposed a settling tank 9 from vwhich leads a waste pipe10. The iiue 1 is provided in its sides with suitable doors Sfrarr v l -sMoKs-ruizrsrnn.

I Wish 1t to be further understood that'I do not limit myself to the use of the tank 3 since `water or othersuitable liquid mayv be suppliedwdirectly `from pumps or jother suitable source.

When it is desired to clean orrepair the ue or stack 6 the gate-2() is lowered thus shuttin -oii'l communication with the receiver 8' and, t e damper 27 being opened, the prod-l u cts ofcombustion escape' directly through the'auxiliary stack 24.

It will thusbe seen that I have provided :an apparatus which is very simple 'and esilicient, which' contains no tortuous or inaccessible passages liable to become clogged' land which can be readily attached toanyv 'ordinary`furnace, and it is thought the nuwhich said flue, empties, astack extending ing romgsaidreceiver, anda second stack connected with said last-,named flue.
