PEGFICATION forming part of Letters Patent No. 728,098, dated May 12, 1903.

Application iiled August 6, 1902.

will produce thorough combustion of the hyu drocarbon delivered thereto and to combine with such a burner a body of heat-dissemiinating material of novel form.

Another object of the invention is to pro- I vide means by which the hydrocarbon sup' plied to the burners can be maintained at any desired pressure and such pressure automatically regulated.

Figure 1 of the accompanying drawings is an elevation and partial section of an apparatusconstruoted in accordance with the present invention. Fig. 2 is a` detail sectional -view of one of the burners ou an'enlarged scale.

Referring to the drawings, V1 designates a reservoir for hydrocarbon, which may be of any desired size and form and, as shown in the drawings, may be buried or arranged bedow the level of the several parts of the apparatus. The hydrocarbon is drawn from said reservoir by means of a suitable pump 2 and delivered to a pressure-tank 3 through Aa pipe 4. Said tank 3 is provided with a gage -5 for showing the height of hydrocarbon in the tank and with an indicator 6 for recording the amount of air-pressure therein. .Air under pressure is supplied to the tank 3 from an air-pump 7, which is connected with said tank by pipes S 9. Steam for actuating the hydrocarbon and air pumps is supplied through branch pipes 10 1l, respectively, from a main 12, which is connected with any suitableboilerorsteam-generator. (Notshownin the drawings.) Suitable valves 13 14 are provided in the pipes, by which hydrocarbon and air are supplied to the pressure-tank 3, and

Serial No. 118,654. (No model.)

an auxiliary steam-pipe 15 connects the airsupply pipe 9 with the steam-main 12. By means of this auxiliary steam-pipe steam can be supplied to the pressure-tank, if desired.

The upper end ot' the pipe 8 is extended some distance above the plane of its connection with the pipe 9, and on said projecting section is arranged a pressure-regulator of any desired and suitable style, which is connected to one end of a short rod or link 16. Theotherend of said link is connected with a lever 17, which is fulcrumed at one end at 18 upon a bracket or standard 19, secured to the said pressure-regulator. The other end of lever 17 is connected, by means of an extensible rod 20, with an arm 21, extendinglatf thedesired amount, the said steam-valve will be'automatically opened and the air-pump 7 again set in action.

Hydrocarbon under pressure is conducted from the tank 3 to suitable burners through a pipe 22. The burners employed are preferably of the form illustrated in detail in Fig.

2, consisting of an inner hydrocarbon duct or r tube 23 and an outer concentric cylinder 24. The lower end of the tube 23 is suitably connected with the pipe 22, leading from the tank 3, and in the upper end thereof is fitted a plug or stopper 25, having formed therein suitable passages or openings through which the hydrocarbon` escapes in the form of minute streams or spray. The outer cylinder 24 of the burner, which forms a carburetingchamber about the tube 23, may be of metal and is detachably connected at its lower end to the upper iiaring end of a bowl-shaped sleeve 26. This sleeve is detachably connected to an upwardly-extending portion of a collar 27, which is secured to the inner burner-tube 23 by a screw 28 or by any other suitable means. In the lower portion of the sleeve 26 are formed a series of apertures 29, through which air can enter the outer cylinder 24, and through one of said apertures projects a steam-nozzle 30, that is connected to a branch 3l of the main steam-pipe 12.

In applying my improvements to a steamboiler furnace,such as is conventionally illustrated in the drawings, I build up on the regular grate-bars 32 or other suitable supports a bed of heat-disseminating material consisting of alternate layers of asbestos 33 and firebrick 34. The layers of fire-brick are arranged so as to provide in each a series Of Openings or fines 35 and preferably are so arranged that the said apertures in one layer will he out of alinement with those in the succeeding layer. Any suitable number of layers of brick and asbestos may be employed. The burners extend up through passages between the grate bars or supports 32 and are completely surrounded by the lower layer of asbestos. Preferably, as shown, the burners are arranged in alinement with Openings or spaces 35 between the members of the lower layer of fire-brick and the upper ends thereof are situated a short distance below said layer 0f brick.

By means of suitable valves 36 37 the supply of hydrocarbon and steam to the burners can be regulated, as desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In an apparatusl for producing heat from liquid fuel, the combination of a body of material consisting of alternate layers of asbestos and refractory substances, burners embedded in the lower asbestos layer of said body and each consistingr of an outer cylindrical body and an inner tube of relatively small diameter, a series of air-inlets Opening into the lower end ofthe space between said tube and cylinder, a steam-nozzle extending into the said space, and means for supplying liquid fuel under pressure to the inner tubes of the burners.

2. In an apparatus for producing heat from liquid fuel, a burner consisting of a tube Or pipe adapted to be connected at one end to a conduit for supplying the liquid to be burned, and having at its other end a perforated plug, a collar secured about said burner, a perforated sleeve detachably connected to said collar, a cylinder having a threaded connection with said sleeve and extending beyond the free end of the aforesaid inner burner-tube, and a steam-jet extending into the space between said tube and cylinder.

3. In an apparatus for producing heat from liquid fuel, the combination with a reservoir for such liquid, a tank, a pump adapted to force the liquid fuel from the reservoir to said tank, an airpump adapted to deliver air under pressure to said tank, steam-pipes for conducting steam to said pumps, a pipe leading from said tank, a series of burners connected with said pipe and extending into the furnace or other place to be heated, a body of infusible material surrounding said burners, a steam-nozzle extending into each burner, a rod connected with a pressure-regulator adapted to be affected by the air-pressure in the pipes connecting the air-pump and said tank, a lever connected to said rod to be moved thereby, and an extensible rod connecting said lever with a valve in the steam-supply pipe of the air-pump, whereby when a predetermined air-pressure is attained the supply of steam to the air-pump will be automatically cut oif.

In testimony whereof I affix my signature in presence of two witnesses.

JOI-IN GREER.
