To all whom it may concern.-

Be it known that I, GEORGE ROSE, a subject of the Queen of Great Britain, and a resident of the city of Glasgow, Lanarkshire, Scotland, have invented certain new and useful Improvements in Apparatus for Burning Hydrocarbon or other Oils for Lighting and Heating Purposes, (patented in England November 13, 1889, No. 18,101,) of which the following is a specification.

My invention relates generally to apparatus for burning hydrocarbon or other oils in the form of spray for lighting and heating purposes; and the improvements are mainly applicable to that class of apparatus wherein steam generated from water supplied to a coilpipe or chamber heated by the flame is used to spray the oil or oil-vapor in the burner or' consists in certain improvements applicable to such apparatus; and in order that my said invention maybe properly understood I have hereunto appended two explanatory sheets of drawings, whereon- Figure 1 shows partly in side elevation and partly in section a spray-lamp. Fig. 2 shows in side elevation a different arrangement of spray-lamp. Fig. 3 is a vertical section of a spray-lamp; Fig. 4, a side view, partlyin section, of a spray-lamp; Fig. 5, a vertical section of a spray-lamp. Fig. 5 is a plan view of the basement-tanks, Fig. 5. Fig. 6 is a detail View, partly in section, to an enlarged scale. Fig. 7 is a side view, partly in section, of a spray-lamp. Fig. 8 is a vertical section of an oil-well burner. Fig. 9 represents in sec-' tion an annular steam-generator as being used instead of a coil-pipe.

On the drawings the same reference-letters,

wellburuer D. (bhown enlarged at Fig. 8.) It is of a similar construction to the burners of my prior patents, except that the top of the burner is in this case shown as made with a broad flange D, to which is secured the combu'stion-box or'casing E.

F is the coil-pipe for generating steam, and it is supplied with water from the tank A by means of a pipe connection F.

Oil is supplied fromthe tank B to the oil-well of the burner D by means of the pipe G,which is provided with acontrolling-valve G. The self-generated steam from the coil F is conducted down to the steam-chamber F of the burner by the pipe F The pipe F has or may have a regulating-valve F on it.

In the present invention there is connected to the pipe F a pipe H, leading to the top or other part of the water-tank A. This pipeis for the purpose of conducting some of the self-generated steam to the tank A, so as to create a pressure therein, and thus obviate the necessity of forcing in air under pressure by means of a hand-pump, as formerly. The

burner-nipple D has an opening or orifice of such size in it that there will always be sufficient steam generated in the coil F by means of the heat of thelamp-fiame as will supply sufficient steam to give a steady andregular pressure in the water-tank A and also to spray the oil.

In connection with the water-pipe F is or may be fitted an automatic supply-regulating valve l. The valve consists of a casing 1, (shown more particularly at Fig. 6,) in which works a piston or plunger 1 The casing is narrowed-at one end, so as to form a seat for the piston, and is screwed or otherwise fitted into the sideof the water-tank A. Connected to the piston I is a piston-rod I, which passes out through a stuffing-box I and through a slot I (shown dotted) or its equivalent in the handle I of the stop-cock 1 which latter may be of the usual construction. The piston-rod I may have stops 1 on it, so that when the piston is traversed back and forward the handle of the cock I will be reciprocated and the supply of water out off or turned on. The casing 1 is open at its inner end 1 To keep the piston I normally closed against its seat, a spiral spring I or equivalent is provided.

This spring bears on the casing cover 1 which may be perforated, and the back of the piston I WVith this arrangement when the lamp has been started, which may be done by means of naphtha or other volatile oil being poured into the box or casing E and ignited, so as to generate sufficient heat to convert the water in the coil into steam,the steam passes from the coil down to the junction of the pipes F and H, where it divides into two streams, one passing to the burner-nipple to spray the oil and the other passing up the pipe H to the tank A and creating pressure therein. On the steam-pressure in the water-tank becoming great the piston l of the valve I is forced outward against the action of the spring I and the piston-rod traverses the handle I of the cock I and so cuts oit the water-supply to the coil. On the pressure falling the spring I forces back the piston to its original position for water-supply. The valve is or may be so arranged that, as shown, the cock I will be open when the piston I is closed against its seat and the cock will be shut on the piston being forced outward, although it may be arranged to operate in an opposite manner.

The tanks A B may be mounted on top of a trestle or may sit on a bracket.

The lamp shown at Fig. 2 has a cylindrical oil-tank 13, supported on three legs or supports J. The water tank A is in this case The Water-tank is, as shown, preferably of smaller diameter than the oil-tank B, as a much smaller supply of water is required for the lamp than oil. filling-tube J, to which water from the main or other source is supplied to fill this tank A. The burner D is of the same construction as in Fig. 1. The automatic supply-regulating valve I is not shown as applied to this lamp. With this arrangement the steam-pressure from the generating-coil is at first allowed to pass into the top of the water-tank through the pressure-pipe H, so that the pressure in p the tank will balance the pressure in the generating-coil. If pressure were not admitted to the water-tank A through the pipe I-I, there would be a back-pressure along the watersnpply pipe F, which is, together with the ter up to the same level as in the water-tank when the valve 1 is open, and as a consequence water would flow irregularly, and thus cause the lamp to go out. By having the pressure in the tank and in the generatingcoil balanced, as aforesaid, water will flow in small quantities, as required, into the gencrating-coil. When starting the lamp, a small quantity of water is supplied by gravitation to the generating-coil by opening the valve 1 on the water-supply pipe. The valve I may, if desired, be dispensed with.

In Fig. 3 a lamp is shown having a large oil-tank B, fitted with a pocket A on the inside for holding the necessary supply of water. The pocket A, as will be seen, is fitted icoil of the burner. sists of a coil N, fitted on top of or it may be burner.

supplied with water direct from the tank A by means of the pipe connection N, and steam to that side of the tank B which is nearer to the lamp-burner, in order that the heat radiated off the flame may heat up the imprisoned air in said pocket and cause it to expand, and so create pressure therein. The pressuresteam from the generating-coil F is led into pocket A by the pipe H, which in this case has a valve J on it to regulate the supply of steam to said pocket. The water-supply pipe F is shown as having asiphon-bend F on it, which is for the purpose of keeping a supply of water in the generating-coil F. The bottom of the casing E is shown in this case as ei g used as the oil-well of the burner D. With this arrangement when starting, the Water is supplied from the pipe F by opening the valve 1 and as it comes into contact with the heated surface of the generating-coil F steam is at once generated and by opening the valve J on the steam-pressure pipe II is passed into the water-pocket A to create or increase the pressure therein. This being done, the steam-supply to the water-pocket may be turned off and the steam-supply to the burner turned on by means of a valve on the connection F (not shown 011 the drawings,) so as to maintain the flame by spraying the oil or oil-vapor in the casing E. The

I pressure in the water tank or pocket A can be thus maintained by turningon a supply of ,steam at intervals from generating-coil F. fitted to the under side of the oil-tank B.

The pocket may be inclosed in a casing form- :ing an air-jacket, so as to retain the heat. The oil is supplied by gravitation, as in the case of the arrangements at Figs. 1 and 2.

The water-tank A has a The lamp shown at Fig. t works in thesame manner as the lamp Fig. 3, the only diiterence in the construction of this lamp being that the water-tank A is supported or held v 1 out from the oil-tank B by means of straps c.

The lamp is shown as fitted on a trestle L, which is broken away. In this lamp the l valve F is shown for turnin on steam to the 0 burner D.

In Fig. 5 the lamp is shown with a crescentshaped oil-tank B, and into the hollow of the crescent is fitted the watertank A. The

With the arrangement of steam-pressure tanks hereinbefore described not only is the necessity for repeated pumping obviated, but the water in the water-tank is warmed sufficiently to facilitate a rapid steam generation in the generating coil or chamber.

A whistle may be fitted on top of the pressure-tanks to indicate when the pressure has reached a certain point, so that the attendant can then cut off further supply of steam.
