OIL-BURNER.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed December 12, 1912. Serial No. 736,325.

To all whom 'it may concern ,Re it known that I, BENJAMIN ROBERT tRpLPH, of the city of W'innipeg, in the Provfince of Manitoba, Canada, have invented cerltain new and useful improvements in il- Burners oi' which the foiiowing is the specification.

f l The invention relates te en improvement iin oil burners and the object of the invention oistto provide a convenient and econoinicai E mea'ns for utilizing the thermal energy of :coinrnon oii or ether fluid hydrocarbons.

.1', The invent-ion consists essentially in the Q arrangement and construction of parts here- 15 tin'ziiter more particularly described and later Lpointed out in the appended'claims'.

t, lVFigure l represents a longitudinal sectional View through the device parts being f .fslioivn in side elevation. Fig. 2 represents 2U\a"1vzertical cross sectional View through the samer the section being taken in the plane den, ed by the line XMLX Fig. 1 and loolziing tihddirection indicated by the arrow a Eiglij represents a. vertical sectional" View tlitongh the device, the section being taken inltlhejplane denoted by the line Y-Y Fig. l fluidilooking in the direction indicated by thelhiiiiow b. Fig. 4C4 represents an enlar dfMdetailed horizontal sectional view throiigiiltbe needle valve seat and adjoining parts;A p. prt of the valve being shown in side eleviitliiiil.

In'tn a drawing like characters of reference eradicate corresponding parts in each figure, .y l

1 represents a tubular member having the ends theneoi Yclosed by caps 2 and 3 and divided centrally by a cross piece 4 thereby providing\a vaporizing chamber 5 and a superheating chamber 6 at opposite sideof the partition 4.

7 is a tube passing through the cap Sinto the tubular member 1 which tube passes more or less centraliy through the partition 4 and terminates in a closed end a short distance away from the cap 2; This tube is connected with a suitable oil supply controlled by a stop cock 8 inserted in the tube. The end of the tube within the vaporizing chamber is provided on the top side with a series of small holes 9 to admit the oil to the vaporizer when in use. A. packing of as'- bestos, mineral Wool'pumice stone or other such like nan-combustibie materiel 10 is 55 placed within the vaporizing chamber and beneath and to the sides ofthe tube, cere be ing taken that the holes 9'are not closed or which brackets are looped around the tubular member 1 to support the same above the pan.

15 represents a burner located beneath the' tubular member 1 and supported in any suitable manner by the brackets. The burner has a series of openings 16 located in the upper side thereof and'has one-'end pcrmancntly closed by a cap 17, the opposite end being fitted with a contracted coupling pipe` 18 which receives the inner end of an ex tending pipe 19 fitted with a series of ain inlet openings 20 and carrying an adjust able sleeve 2i, the sleeve being arrangedto close when desired the openings thereby -ermittmg ofa variation of the amount o air fed into the pipe through the openings:

22 is a valve casing carried by the forward end of the pipe 19 into which it opens. The

casing is fitted with a valve seat 23 and an orifice '24 and carries a stuffing box 25 itted With a valve 26 having the stem 27 theof threaded into the box for adjusting purposes. The outer end of the stem is supplied with a hand piece 28 and the Vinner'end is contracted at 29 to form a shoulder 30, designed to close on the valve seat 23, the contracted portion of the stem being designed to pass into and through the orifice 24 for cleaning purposes.

I 31 is a pipe having the forward end openingto the interior of the valve casing and the rear end thereof passing through the cap 3 into the interior of the superheating chamber.l

32 is a drip pipe passing from the pipe- 7 downwardly toward the pan. This is supplied with a stop cock 33. f

In the operation of the device a small quantity of oil is allowed to run into 'the pan through the pipe 32, this being accom'- plished by turning the stop cock 33. When sufficient oil is in the pan said stop cocky is closed vand the oil is admitted to the va porizing chamber by opening the stop cock 8. it being understood that the oil is passed packing so that the oil contained therein is vaporized and passed to the superheater through the port l1. From the snperheater the vaporized oil enters the pipe 3l and passes to the burner, the amountI being regulated by the valve. In passing through the superheater the vaporized oil is heated to a high temperature and converted int-o a gas, it being noticed that. the superheater is located in the zone of the iame arising from the pan. Prior to entering the burner the gas is mixed with air passed through' the openings 20, the supply of this air being readily controlled by the attendant through the manipulation of the sleeve 2l, By the time the oil in the pan is exhausted the gas is flowing freely through the openings 16 in the burner where it amply serves to keep the Vaporizer and superheater up to the required temperature.

The contracted end of the valve serves the important function of cleaning out the orifice 24 each time the valve is closed. If no such provision were made the orifice would become quickly clogged with carbon particles after the burner had been in use for a shorttime. This Would greatly depreeiate the use of the device.

The burner is particularly adapted for placing in the ordinary stove to convert it into an oil stove or to be used in connection with Wat-er heaters or boilers. other uses can readily be found for it however embodying the essential features of the invention. Y

l/Vhat I claim my invention is l. In an oil burner, the combination with a burner and a vaporizing chamber, of a superheating chamber adjoining the vaporizing chamber and opening to the same, an

oil feed pipe passing through the superheat` ing chamber and into the vaporizing chamber, said pipe having the portion entering the vaporizing chamber fitted with a series of openings, a packing Within the Vaporizing chamber and adjoininj the pipe and means connecting'the superneating chamber with the hnrncr, as and, for the purpose specified.

Q. In an oil burner, the combination with a burner and a vaporizing chamber, of a si'iperheating' Chamber adjoining the .f'aporH izing chamber and opening to the same, a feed pipe passing through the superheating cnamber and entering the vaporizing cnamber, said pipe ,having the portion thereof entering the latter chamber provided with a series of openings, a packing within the vaporizing chamber and adjoining the pipe, a pipe leading from the superhcating chamber and communicating with the burner, means tor controlling the passage of the vaporixed oil through the lutter pipe and adjustable means for mixing air with the vaporized oil prior to admitting the saine to the burner, and for the purpose specified, 3. In an oii burner the combination, with a burner and a vaporizing chamber, of a superheating chamber adjoining the vaporizing chamber and opening to the saine, a feed pipe passing through the superheating chamber and entering the vaporizing chamber, said pipe having the portion thereof entering the latter chamber provided with a. series of openings, a packing Within the vaporizing chamber :ind adjoining the pipe, a pipe leading from the superheating chainber. a pipe extending from the burner and provided with a number of openings, an adjustable sleeve on the latter pipe, a valve casing connecting the ends of the latter pipes, said casing presenting a valve seat, and a valve operating on the seat, as and for the purpose specified.
