CRUDE-OIL BURNER,

SPECIFICATION forming part of Letters Patent No. 552,813, dated January '7, 1896. Application filed March l, 1895 Serial No. 540,238. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS J. Bnoucn, of Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Crude-Oil Burners, of which the following is a specification.

The object of my invention is to provide an oil-burner for the use of families, metal-refiners, artisans, manufacturers, and othersin fact, for all uses for which an efficient heat is required without the use of explosive gasoline.

The difficulty heretofore in burning the heavier oils has been in the tendency of the vaporizing-pipe to become clogged and stopped up by the heavier products of the oil, which soon stops the operation of the burner. My invention overcomes this by a separation of the oil in the burner itself into a lighter and easily-vaporized oil, and a heavier oil which is drawn off and either burned through a separate nozzle by the aid of the pump or else drawn off and utilized for other purposes, such as lubricating-oils, (TIC.

Figure 1 is a side elevation of my improved oil-burner partly in section, and Fig. 2 is a vertical section taken through the burner.

In the drawings, A represents a coil of pipe of a generally conical shape, the larger diameter of coils being at the top and the smaller ones at the bottom, forming a flame-space or fire-chamber within, increasing in size toward the top. This coil communicates at its upper end through a valve T with a reservoirtanlc T for the oil-supply, which may be either crude oil or the heavy ordinary coal-oil of commerce. At its lower end this coil communicates with nd terminates in an upwardly-directed burner-nozzle A, having a screw-valve A by which the issuance of vaporized oil into the fire-chamber is regulated. At an intermediate point in the length of the coil A there is interposed a separating-chamber B, composed of a cast-iron box, or a large T- coupling,- from the lower side of which there extends apipe B,which, through a valve leads to a heavy oil-tank U. This separating-chamber has screw-threaded couplings for the pipe B and the connecting ends of the coil A.

G are'air-draft pipes which at their upper ends have bell-shaped or flared months that turn over and open downwardly into the firechamber within the coils and after passing down on the outside of the coil A turn upwardly and open into the fire-chamber beside the burner-nozzle A. These air-pipes are preferably three in number, but may be more or less, and they are connected to the coils in any suitable way, so as to form a sort of framework therewith to hold the coils in place. The coil and airpipes are seated and sustained within a tripod stand or frame D composed of vertical legs and horizontal circular bands, and may be either loosely and detachably held therein or fastened thereto, as ma be desired.

The operation of my burner is as follows: Crude oil from tank T being allowed to flow from gravity into coil A by opening valve T and valve A being opened, it is ignited and fills the space within the coilA with flames. The heat of the flame, partly volatilizing the oil in the coil, causes it to issue as a forcible gas at the nozzle A, producing a strong upward blast. The upward blast of this flame draws air by induction upward with it and forces the heated air into the bell-shaped mouth a" of air-draft tubes 0 and causes the heated air to issue at the lower ends 0 of these air draft pipes into the fire-chamber adjacent to the issuing gas and furnishes air in sufliciently rapid and forceful streams as to continue the upward blast and maintain a very perfect continuous and high degree of heat. The oil as it passes down the coil is raised in temperature and quickened into a condition of volatilization, but when it passes the separating-chamber B it is still in a liquid condition and by gravity the heavier portions of the oil which would be liable to clog the burner are taken away through pipe 13" and valve B and deposited in the tank U in a heated condition to be turned outside of nozzle A or otherwise utilized. This burning of these heavier products may be effected through the agency of a pump U valve U, and pipe U which has a spray-nozzle on its end directed into the fire-chamber when the force of the pump causes these heavier products to be sprayed and turned without clogging the burner A, and thus utilizing without smoke or the de posit of carbon the whole of the constituents of the crude oil in a very economical and iclezml y way with the best of results fer lleatl ingrpurpeeee 'Bymea ns 0f the valves T, A l
