HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 520,911, dated J' une 5,1894.

Application filed February 23, 1893. Serial No. 463.295. (No model.)

` To a/ZZ whom iv' may concern.-

Be it known that I, EDWARD E. ASHLEY, a citizen of the United States, residing at New York, in the county of New York and State of'New York, have made certain new and useful Improvementsin Heating Apparatus, of which the following is a specification.

My invention relates to independent or isolated heating devices, and comprises a suitable generator, a coil for circulating steam or hot water leading from the generator and returning thereto, and devices for supplying" the generatorwith Water and for interchangeably using the device for hot water or steam circulation.

generator, I have shown devices for utilizing those mediums.

My invention further consists of the details of structure hereinafter described and further pointed out in the claims.

In the accompanying drawings forming part of this specification-Figure 1 is a sectional elevation of the generator and radiator, with an oil burner secured under the generator for the purpose of heating the same by oil; Fig. 2, a plan and cross section of Fig. 1, taken approximately on the line a: a: of that gure; Fig. 3, a bottom view of the generator with the burner removed; Figs. 4 and 5, respectively, plan views of the metallic and asbestus gaskets; Fig. 6,"a diagrammatic view showing a device for automatically regulating the amount of heat supply to the generator and thereby the temperature of the hot water or the pressure of steam in the regulating and circulating coil.

Like numerals ,of reference refer to like parts in all the views.

In the drawings lis a cast iron base of any suitable form or construction, and upon this is mounted a preferably circular jacket 2 having perforations 3 therein, the jacket being secured upon the base by the angle iron 4.

The generator consists of a cast iron shell 6 having at the bottom an annular dome 7 a having a ledge 7. The shell is provided with lugs S at each side (see Fig. 3) by means of which the generator is bolted to the top plate 9 of the base 1 by means of the bolts 10. Dependingfrom the bottom 11 of the shell 6 are ears 12 against which abut ears 13 depending from the top plate 9 of the base 1. Secured within the dome 7 is a circular and preferably convex crown sheet 14: of copper so as to readily transmit the heat, and between the metal and the ledge 7 and the crown sheet is interposed an asbestus gasket 15 provided' with a series of holes 16, and below the crown sheet lies a collar 17 likewise provided with holes 18, the gasket 15, crown sheet 14 and collar 17 being secured in the dome 7?' by means of the nut bolts 19 which pass through the holes in both the collar and gasket. The crown sheet is thus detachably secured, so that it can be readily removed if burned out.

The circulating and radiating coil comprises a vertical stand pipe 2O which enters the top of the shell 6 in the usual way, and connects by means of an elbow 21 with the sections 22, 23 united by the elbows 24, the sections 22, 23 and elbows 24 being'continued downwardly in turns which return to the generator through the elbow 25 and short pipe 26.

The particular form of coil and the configuration of the generator is immaterial, except that I desire to use a vertical riser 20, and let the hot water or water of condensation return by gravity to the generator, the return inlet being below the top of the shell 6.

It it is desired to use oil as a heating rnedium, af multi-wick lamp, such as shown in Fig. 1, can be used, which comprises the reservoir 27 having the burners 28, and filling vent 29 which is secured by arms 30 to both the ears 12 and the ears 13 by means of the bolts 31 which pass through them. -A pet cock 32 secured to one of the turns of the radiating coil extends from without the jacket, and can be used for the purpose of 'testing the coil for steam or water.

It is apparent that if heat is applied to the crown sheet of the generator, the water there- IOO the following: Secured to the top ofthe jacket.

is a tank 33 of any suitable size, which extends above the top of the coil, the tank and the shell 6 being connected by a stand pipe 34which` enters the top of the shell in the usual way.` It is apparent that if water is poured into the tank, which water has a sufficient head,it will iow into the shell up into the stand pipe 20, then downward through the t turns of the coil, back to the generator again, completely iilling both the coil and the gen- `erator, after which connection between the tank and the generator can be closed by means of the valve in the pipe 34. The pipe 34 is located within the coil and becomes heated by radiation therefrom, and to supply warm or cold water, as before set forth, the pipe 34 and tank are filled with water, the valve 35 closed and the water therein permitted to remain long enough to become heated, when the valve 35 can be opened and a fresh supply of warm waterfrom the stand pipe and tank 33 can besupplied to the generator.` The tank 33 can be put in direct communication with a regular l source of supply by means of the pipe 36, in which a valve 37 is interposed, or a funnel 38 can be used, as shown, to eitherconstantly supply water or to give a supply of water, and controlled by the valve 37, to make ,np for` the loss of water by evaporation or leaking. As will be seen from Fig. l the tank "33 is closed, except when the valve 37 is opened to permit of the entry of Water. If steam is to be used as a heating and radiating lnedium then the cock 35 in the stand pipe 34 will be closed. It a hot water circulation is to be used then the pipe 34will be filled with water and the cock 37 closed.

" If it is desired to use only heated water as a circulating medium, the generation of steam can be prevented by using gas or oil burners of suiicient size to only heat the water to make it circulate; but if steam is to be used tomatic device which will regulate the temperature.` Instead, however, of regulating the temperature by means of the particular sizeof burner, as before described, when hot water is used, I can use an automatic device.

forthis purpose also.` This device I have illustrated with the use of gas as a heating medium.

halves or sections 40, 41 and an interposed` flexible diaphragm 42 to which diaphragm a toggle rod 43 is connected by a pin 44, the rod passing through a stuffing box 45, the two sections 40, 4l and the diaphragm being bolted together, as shown, by the bolts 46.

48 leads to a suitable burner 49 to supply gas or other like heating medium, and interposed in the pipe 48 is a Valve casing 49, the valve stem 50 of its valve being connected to the rod 43 by a lever lhavinga segmental slot 52, and through thelslotiand rod 43 passes a set screw 53, so that by movingthe set screw and arm 43 in the slot 42 the same can be adjusted therein to give the lever 5l var ing throws, and the valve in the Valve casing 49 any desired degree of movement and increase or decrease the `supply of gas or other heating medium. Should it bedesired to heat the water to a degree at whichsteam is generated, the burners being capable of combusting enough of the gas or other medium for this purpose, the play of the lever 5l can be regulated so as to supplyl enough gas to generate steam. Ii' hotwater is only to be made, the relation of the rods'43 and 51 can be adjusted so as to supply but sufficient heating medium for this purpose." It is also plain that the regulator can be'used for burners for hydrocarbon oils as -well as gas.

I-Iaving thus described my invention, I claiml. `The combination with the shell 6, of the dome 7L having an aperture therein, the crown sheet 14 lying within ther aperture, a nencombustible gasket between the crown and the dome, the crown sheetand the gasket being secured to the dome, substantially as described.
