CORTLAND BALL, OF INDIANAPOLIS, INDIANA.

FUEL-OIL BURNER.

SPECIFICATION forming part of Letters Patent No. 483,730, dated October 4, 1892.

Application filed April 1, 1892. Serial No. 427,312- (N o model.)

.To .all whom it may concern.-

Be it known that I, CORTLAND BALL, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Fuel-Oil Burners, of which the following is a specication.

My invention relates to an improvement in fuel-oil burners for domestic purposes.

The object of my improvement is to provide means for finely-dividing and vaporizing the oil which shall be cheaply and easily constructed and readily accessible for the purpose of removing the residuum left by the burning oil.

The accompanying drawings illustrate my invention. t

Figure l represents a central vertical section. Fig. 2 represents a plan at a, Fig. l. Fig. 8 represents a side elevation of the retort.

In the drawings, A designates the gratebars of an ordinary heating or cooking stove.

B is a ilat metallic plate having a central circular raised portion O, in which is a circular opening D. A circular cup E, of slightlyless diameter than opening D, is secured to plate B by means of arms F F in such a manner that the cup is concentric with the opening D and its bottom is in the same plane as plate B, the arrangement being such that air is prevented from passing through the grate except in that portion immediately below the annular space G formed between the walls of the cup E and the raised portion O. Cup E is provided with a central hub H, into the under side of which is screwed the oil-supply pipe I and into the upper side of which is screwed a pipe J, forming a continuation of the supply-pipe.

Mounted upon pipe J is a metallic spool K, having numerous coils of wire L wound thereon. The upper head of spool K consists of a series of arms M or is of other similar open construction,so as to expose the coils of wire. Spool K is constructed so as to slip easily over pipe J and is held in place by a Washer N, which fits tightly over the pipe. The lower head of the spool is of slightly-larger diameter than the upper head,and upon this lower head rests the cylindrical retort O, com- 5o pletely inclosing the upper end of pipe J and the coils K. Mounted upon and supported by the retort O is a circular deflector P.

The operation of my burner is as follows: Oil being admitted through the supply-pipe I 5 5 and overiiowing from the top of pipe J is conducted outward by washer N and is discharged upon the coils K. Flowing downward through the coils K, each of the wires is thoroughly coated with a film of oil, and the 6o surplus passes out between the lower edge of the retort and the lower head of spool K and falls into the cup E. The oil in cup E being ignited, the coils K and retort O become heated, and the oil, being iinely divided and distributed over the surfaces of. the coils, is quickly vaporized and formed into gas, which, passing outward at the lower edge of the retort, is mixed with the current of air flowing upward through the annular space G and 7o burns with a clear ame without soot, which is directed outward against the Walls of the stove by the deflector P.

The difiiculty heretofore encountered in all burners of this class having a vaporizing-retort has been the accumulation of unburned dbris from the oil inthe retort, which dbris under former methods of construction it has been difficult or impossible to remove.

In my device by use of the coils of wire 8o the oil is so thoroughly vaporized that little or no dbris accumulates, and the costruction is such that the retort and vaporizing-coils may be easily and quickly removed, cleaned, and replaced by unskilledpersons Without special tools.

I claim as my invention--i 1. In a fuel-oil burner, the combination, with a vertical supply-pipe, of the spool carrying a series of wire coils and removably 9o secured upon the pipe so as to receive the discharge of oil therefrom upon the coils, and a retort arranged to inclose said dischargepipe, spool, and coils, substantially as set forth.

2. In a fuel-oil burner, the combination of the plate having the central circular raised portion provided with a central opening, the

cup secured to said plate concentric with said ranged to co-operate substantially as and for opening,t1e supply-pipe rrojecting vertically the purpose set forth. above sai cup, the spoo carrying a series of Wire coils and mounted upon said pipe so as CORTLAND BALL' 5 to receive the oil therefrom, and the retort Witnesses:

mounted upon said spool and arranged to H. P. HOOD, inclose the supply-pipe and the coil, all ar- V. M. HOOD.
