'- S OO'I DES'IROYER COMPOSITION.

No Drawing. Application filed September The invention relates to a composition of matter, put up in a powdered form and adapted to be used to destroy soot in furnaces, chimneys and other places where soot is a detriment to the fire and good draft of the same. r

In the use of oil burners which are now becoming quite extensive owing to the perfection of oil burning devices, soot is col- 1* lected more or less within the furnace and the fines and chimney which becomes very, detrimental to the draft after a certain ac-' cumulation of the same. This composition, used in the quantity desired will entirely :5 eliminate and destroy the. soot within the fiues, furnace and other receptacles of the fire chamber or walls of; the fire box, so as to thoroughly and completely cleanse the same.

In the us'eof this composition the destroyv ing of th, soot can readily be apprehended by the burning of the same, in the dull, red fire which creeps along andeats up and destroys the soot out of the lines and compart-' ments when this composition is used on the l fire, so that the burning of the soot takes place in a manner to completely destroy the same, as the soot seems to form a means of causing combustion and-burning in a dull, red, flame which creeps along with thesoot wherever the'sootris deposited arid can readily he apprehended after placing a quantity of this composition in the fire.

In carrying out my invention, I take suitable proportions of potassium nitrate (KNO and charcoal in a powdered and pul verized state, which is thoroughly mixed by any suitable well known mixing means. This mixture may be put up in packages as may he desired, in thequantitydesired, and may go be formed into biscuits or balls which can be conveniently stored and kept for'use In practice I have found that a very effective compound for thepurpose stated is made up by usingthe above mentioned in-- 5 gradients .in approximately the following proportions by weight: potassium nitrate? 5 parts-andchareoal parts; potassium n itrate parts and charcoal 50'parts'. I ldo notdesire to-confine myself to these exact 50 porportions although they "are preferable" and sodium nitrate or calcium nitrate m'ay be used if it "is desired which .are protee tive in some form for soot destroyer in place of potassium nita;ate.- I v I have also found in practice that a. very 16, 1925. Serial No. 58,601.

effective compound for the purpose set forth is made by a composition of ingredients in approximately the following proportions: potassium nitrate 50 to 90 per cent and char-y coal 50 to 10 per cent; also potassium ni trate per cent and charcoal 20 per cent; also.,potassiuin nitrate from 50 to parts and charcoal 49 to 9 parts, together with -1 part sulphur. The sulphur may be increased in parts decreasing the other parts proportionately, particularly the charcoal. The sulphur" increases the combustion in certain places where soot is to be destroyed.

In using my soot destroyer itmaybeapplied in the fire box of a furnace or over the burner of an oil burnerso that the combustion of the composition within thefire box and the flues of the furnace and the chimney are filled with the gases and the combustible particles of: my composition. The charcoal absorbing some of the sodium nitrate in a manner so as to carry the same as the charcoal burns through the intricate parts.of the fines, furnace and chimney as it is known that charcoal in burning sputters and flies so as to carry the burning particles into the very depths of the soot deposit. This'causes the soot to be ignited and combusted and 'to burn in a dull, red, creeping fire-like formation until the entire inner surface is eaten away by the red, creeping fire.

By observation the fire can be watched and' it can be readily seen that the soot is destroyed as the fire creeps along, thoroughlyand completely cleansing the inner chamber of all soot so as to completely destroy the same, In treatinga-furnace orburner with my composition to destroy soot the'desired amount can be applied to the fire until the an soot is entirely removed. The absence of i,

the red, burning creeping fire indicates that the colnpartnients are thoroughly cleansed of all soot. 1":

In"acco rdance.with .the patent'sta'tutes I have described the principles ofopera-tion of my composition for destroying soot and carbon, particles within the fire andthe compartments thereof of a furnace or oil burner, and whileLhave described a particular composition of ingredients together with certain proportions, I desire. to have it understood that these are only illustrative-end that the Y invention can" be carried out by other means and'a'pplied to other uses othenthan those 11 above set forth within the scope of the following claims.

I claim: A

15A compound for treating and destroying soot in furnaces comprising, nitrate and charcoal in powdered ormation in the "proportions of from 50 to 90 per cent of the former to 50 to per cent of thelatter.

2. A compound for destroying soot and carbon comprising, potassium nitrate and charcoal in the proportions of 50 to 90 per cent of the former and 50 to 10 per cent of the latter in a,powdered pulverized formation thoroughly mixed, the composition being used in a powdered form or shaped into biscuits or balls or other shapes substantially as described.

3, A compound for destroying soot in furmoss and oil burners comprising, sium nitrate, powdered charcoal and su phur tassium thoroughly mixed in and about proportions herein described. i

4. A composition for destroying soot com-, prising, potassium nitrate and charcoal thorou hly and completely mixed in and about t e proportions herein set forth.

5.. A compound for destroyin soot com rising sodium nitrate and c arcoal the E rtions of from 80 60 to 95 per cent and t e atter in proporormer of which in the tions of to*5 per \cent.

6. A compound for destroying soot com- 95 per cent of the former, to to 5 per cent of the latter.
