VAPORIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 665,106, dated January 1, 1901.

Original application filed March 21,1898, Serial No. 674,573.

Divided and this application filed March 31, 1899. Serial No.

711,217. '\N0 model.)

To all whom it may concern;

Be it known that I, ARTHUR KITSON, asubject of the Queen of Great Britain, and a resident of Philadelphia, county of Philadelphia,

State of Pennsylvania, have invented certain new and useful Improvements in Vaporizing Apparatus, of which the following is a specification.

The present application is a division of my previous application, Serial No. 674,57 3, filed March 21, 1898, upon which Letters Patent No. 625,755 were issued to me May 30, 1899.

My invention relates to that class of apparatus in which kerosene or other fluid hydrocarbon is vaporized and burned to produce light or heat, and more specifically is designed to produce a certain improved form of vaporizing tube or chamber for use in connection therewith.

The main object of my invention is to produce a more perfect and regular vaporization of the oil and even delivery of the same to the burner and to do away with the needlevalve extending throughout the length of the tube, as heretofore sometimes employed.

The preferred form of my apparatus is illustrated in the accompanying sheet of drawings, in which Figure 1 is a side elevation of a lamp with 0 parts broken away, showing the vaporizingtube in position. Fig. 2 is a longitudinal section of one form of vaporizing-tube. Figs. 3 and 4. show modified forms of tube.

Throughout the drawings like reference- 5 figures refer to likeparts.

1 represents the body of the reservoir of the lamp, containing kerosene or other liquid hydrocarbon under pressure sufficient to force it up through the oil-supply tube 2 to the vaporizing-tube 3, the flow being controlled by the valve 4. The oil in the vaporizing-tube is vaporized by the heat given off from the Vapor-burner 5, within whose heatiog zone said vaporizing-tube is located. The

burner is preferably provided with a mantle of refractory material 6, capable of being raised to high incandescence by the heat of the burner. Preferably the well-known incandescent mantle known as the Welsbach mantle is employed. 7 represents a circular 5o flange or frame supporting the glass globe 7 which surrounds the burner, and 8 is a small alcohol-cup, which may he formed integral with the flange 7 and surrounds the lower portion of the burner 5. 9 is the discharge opening in the vaporizing-tube, and 10 the air and vapor mixing tube through which the mixture of vapor and entrained air is delivered to the burner 5. 10 represents a dripcock for drawing off any of the oil which may be deposited in the lower end of the mixingtube. The other parts shown in Fig. 1 are 'similar to those described in my pending application, Serial No. 674,573, filed March 21, 1898, of which this application is a division, and are not specifically claimed herein.

The vaporizing tube or chamber 3 is provided with any convenient number of apertured pipes contained within said vaporizing tube or chamber, through and around which pipes the oil and vapor are compelled to flow. The said pipes are preferably apertured, at their'ends, as shown in Figs. 2 and 3, although one or more of them may be apertured at the side, as shown in Fig. 4.

In the form shown in Fig. 2 the main tube or chamber is provided with a head 11 at one end, into which the small tube 12 is set, and a head 13' at the other end, into which the small tube 14: is set. More than one set of two tubes. might be employed; but in each case one tube of each set would pass through one of the heads 11 and the other tube of that set would pass through the other head 13 of the main tube. The internal tubes should extend nearly but not quite through the length of the main tube. 15 is a'screw for holding the mixing-tube in proper relations with the vaporizing-tube.

In the modification shown in Fig. 3 the tube 14 of Fig. 2 would be replaced by tube 16, of larger diameter, which surrounds the tube 12, said tube 16 being mounted in the head 13, but not passing through the same, the discharge-orifice of the main vaporizing-tube 5 (shown at 9) being inside of the head 13, while it is outside of the head 13 in the construction shown in Fig. 2.

In the modification shown in Fig. 4 the oil enters through the perforated diaphragm 22 and then passes through one or more openings 23 to the main vaporizing-tube 3.

In the modified forms shown in Figs. 3 and 4 I have shown the oil-supply-controlling valve at a in the end of the vaporizingtube, which is an alternative construction to that shown in Figs. 1 and 2.

The mode of operation of my invention is as follows: The oil-supply valve l or 43 being open oil is admitted to the vaporizing tube or chamber, where it is compelled to travel back and forth in the form of oil or vapor through the internal apertured tubes or pipes shown and between the outside of these and the interior of the main vaporizing tube or chamber in a series of fine streams or thin films. In the construction shown in Fig. 2 it passes first through the apertured pipe 12, then back along the exterior of the same, through the main vaporizing tube or chamber 3, then enters the apertured pipe It, passes through the same through the head or diaphragm 13, and out through the discharge-opening 9 of the main vaporizing tube or chamber. In the construction shown in Fig. 3 it passes through the apertured pipe 12, then back between the exterior of said pipe and the interior of pipe 16, then between the exterior of said pipe 16 and the interior of the main va porizing tube or chamber 3 to the dischargeopening 9. In the construction shown in Fig. 4; it passes through the perforated diaphragm 22 into the apertured pipe 16, through the ap erture 23 therein,'and along the exterior of said pipe 16, between it and the interior of the main vaporizing tube or chamber 3 to the other end of pipe 16, then back through the apcrtured pipe 16, between it and the exterior of pipe 12, then into said pipe 12 by the left-hand aperture along said pipe and out through the right-hand aperture into the main vaporizing tube or chamber 3, and is discharged therefrom through the opening 9. In each case the oil and vapor are brought into more immediate contact with the hot vaporizing tube or chamber 8 than has been the case with the old form of vaporizing-tube, and its passage through said vaporizing tube or chamber has been impeded and the period of contact prolonged. The result of this is a more complete and perfect vaporization of the oil. Another advantage is that the compelling of the oil to pass through a tortuous series of passage-ways and impeding its progress throughout the tube serves to overcome any pulsations or inequalities of flow which have heretofore rendered the operation of the lamp irregular. Another advantage arises from the fact that the internally-arranged tubes or other bodies are in metallic connection with the main vaporizing-tube and become intensely heated therefrom, and thus present a large heating-surface to the passing current of oil and vapor and a 'large heatcarrying body of material which will be less affected by the inrush of an unusual quantity of cold oil, and thus again the even action of the vaporizing apparatus is preserved.

It is understood, of course, that various changes could be made in the details of the apparatus embodying my invention Without departing from the spirit and scope thereof so long as the relative arrangement of parts shown in the drawings or the principle of operation described in the specification is preserved.

Having therefore described my invention,

what I claim as new, and desire to protect by Letters Patent, is- 1. In a lamp the combination of a vaporizingchamber with an apertured pipe located within the latter, and in communication therewith at its opposite ends.

2. In a lamp the combination of a vaporizing-chamber, an apertured pipe within said chamber, and a perforated diapllragm located within said chamber at or near the end of said pipe. 1

3. A vaporizingtube which is closed at each end and has a set of two internal tubes of less diameter parallel to the axis of the main vaporizing tube, but not extending the entire length thereof, one tube passing through one head of the main vaporizing tube, and the other one passing through the other head of the main vaporizing-tube, substantially as described.

at. In a lamp the combination of a vaporiz ing-chamber with an apertured pipe located within the latter and in com mnnication therewith at its opposite ends,- said pipe extending nearly the entire length of said vaporizingchamber.

Signed by me at Philadelphia, Pennsylvania, this 28th day of March, 1899.

ARTHUR KITSON.
