To all whom it my concern.-

Be it known that-we, DANIEL S. JUNEahd PETER J; JUNE; citizens of the United .States,--

residing at Fremont, inthe county oiSan 5 dusky and State of Ohio, have invented a new and useful Smoke-Bleacher, of which the -fol-. lowing is a specification. 1

Our invention relates to sin-improved methed and apparatus-I01, bleaching srnoke that re arises from bollergfurnaees'or any smoke-prodncing nnisance; and it has tor its object'to provide a simple andefjfective apparatusthat ywill hleachthe.smekesnd-eonduct itinto the z'ltmosphere. oleanand "colorless, retgining' r5 sperksnor-large' incandescent particles oi ear-4 hon which might, cause oonfiagrations; andavoiding the unclean and disagreeable'eijfeats produced by the escape of the "smoke directly froan the. fnrnaee'aud also meow-- notion as a smoke-hleaehe'r anapparatus that can-he -use'tl for diminishing. or inoreasing the'draft of the boiler or inrnhoe at will; s-n'd it consists of an apparatus connected 5 itli the smoke-stack of the smoke and bleaching chambers providedjwith de-. tails of construction hereinafter"more-fully described; illustrated in .the accompanying drawings, and particnlarlypointpdout in the, pen d a In the aecom'panying drawings; Figure 1 is a perspective view of our improved cleaning .and bleaching apparatus oonnected'with the smoke-stack of an ordinary boiler furnace.
