To all whom it may concern: 7

Be it known that I, JOSEPH PEARSON GILL, of the city, county, and State of New York, have invented a new and useful Improvement in Processes of and Apparatus for Manufacturing Heating-Vapor; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates toan apparatus and method for vaporizing petroleum or other liquid hydrocarbons for heating purposes. It consists, first, in combining with said liquid hydrocarbons heated air and superheated steam in a vaporizer, in regulated proportionate quantities, at temperatures at or above the boiling-point of the liquid employed and below that of destructive distillation, and in delivering the commin gled hydrocarbon vapor, heated air, and superheated steam to burners .in furnaces, where the air is supplied automatically in the proportion required to effect the perfect combustion of the commingled gaseous vapors.

It also consists in the automatically-regulated forcing devices for supplying and maintaining the definite proportions and relative quantities of the air, liquid, and steam used in connection with the hydrocarbonsupply and heating apparatus, and in the means employed .for operating the same, of which the following is a description, illustrated by the accompanying drawings.

In the drawings, Figure 1 represents a side elevation of the apparatus, partly in section,

and with the various pipes exposed to view. Fig. 2 represents in detached position the airforcing device with its automatic regulators.

Fig. 3 shows detached "and on enlarged plan an automatic regulating or pressure-reducing device for the steam-pipe.

In the drawings, A represents a furnace with burners adapted to burn dry highly-rarefied gaseous hydrocarbon vapors, heated air,

and superheated steam, from which the superheated steam maybe omitted. A furnace, W,

contains superheaters and vaporizers. I provide, also, an air pump, preferably rotary, (marked -D,) an engine, 6, for working the pump, a compensator, G, on the pump, consisting of the float f in a tank-valve, 12, located between the tank and the inlet-pipe of thepump, the

tity to the inlet of the pump through the pipe t, the valve o of the compensator, and the pipe to. This maintains a uniform pressure in the pipe K. By adding or removing weights on the float f, or by means of a spring or corresponding device, the pressure in the outletpipe from the pump may be varied at will without suspending operations. It will be understood that the valve opens and closes as the float rises or falls. A register, H, records the number of revolutions of the pump D and indicates the quantity of air passing. The pipe K leads from the pump to the superheater 0, having a pressure-gage, I, and a valve, Y. The superheater 0 beats the air forced through it by the pump D, the air being thence conveyed by connecting-pipe O to a second superheater, E. Above the furnace is a tank for holding petroleum or other liquid hydrocarbon, with a valve, T, through which the liquid passes to siphon-pipe L in a pipe, M, connected to the superheater or vaporizer F. y

In order to maintain the proper proportion between the heated air and hydrocarbon vapor, a governor, V, attached to valve T, is operated by means of connections Q with the pump D, so that the pump, moving faster and forcing more air through the superheater, at the same time opens the valveT wider, admitting corresponding increase in the flow of the liquid to the vaporizer, and decrease in the revolutions in like proportion decreases the. flow. Thus an exact proportion is maintained between the superheated air and hydrocarbon vapor. The vapor is taken up andrarefied by and becomes thoroughly commingled with the heated air from superheater E. Thus mixed, they pass from superheater F through pipe I? to the fire-box or furnace A through proper outlets a at, these outlets having suitable burners for gaseous vapors.

An air-pump, D may be used to supply additional air through pipe 19 to the burners. The pipe p has a pressure-gage, 'i, and a meter, m, may be used on the other side of the pump D to measure the amount of air fed to the pump when great accuracy is required but the amount of air may also be known by the.num-

her of revolutions of the pump, which is driven,

as represented, from the pump D; but each of course may be independently regulated.

It will be understood that the amount of air supplied to the furnace is exactly proportioned to the requirements of the vapors to produce perfectcombustion,allotherairbeingexcluded, and the proportion is maintained by means heretofore described. This rarefied and dry vapor secures constantly a perfect combustion, free from smoke, deposits, and obstructions, which heavy and moist vapor would cause. I use preferably with one gallon of petroleum about six hundred and fifty (650) cubic feet of air, varying with the quality of the liquid used. The superheaters and the vaporizers may be of any suitable and known form.

The boiler B supplies steam for working the pumps, and also to mix with the hydrocarbon vapor in the vaporizer F. It is conveyed through a pipe, N, to superheater E, in which the steam is superheated, together with the air from superheater O, and the combined air and steam pass through the pipe 0 into the vaporizer F, where they are mixed with the hydrocarbon vapors. \Vhen steam in the proper proportion is thus combined with the air and vapor it has the effect of expanding and rarefying the vapor to a still greater extent, and of adding to the intensity of the heat in the furnace. It has also a further tendency to preventdeposits and obstructions in the combustion-chamber and passages thereof.

The steanrpipe N has a regulator, l, with a valve, v on its outlet-pipe, securing uniform given pressure in the section of pipe between the regulator It and the valve r, and a uniformgiven flow of steam through the valve v to the superheater-E. This regulator is shown on larger scale in Fig. 5. It shows a flexible diaphragm, r, and valve W, on the line of the pipe, and a pipe, t leading from the outletpipe into the chamber underneath the diaphragm. Increase of pressure in said outletpipe thereby raises the diaphragm, the pressure closing the valve at r and reducing the flow of the steam. The fall of the pressure below the normal amount reverses the operation and opens the valve, allowing larger flow. By these means a constant and known quantity of steam is automatically passed through the valve 2), and may be varied at pleasure. The pressure of the flexible diaphragm 1' may be varied by means of weights, a spring, or an analogous device.

The liquid-supply pipe M also has an automatic regulator, 1t, and valve o, for regulating the supply of the liquid, which have a similar construction and operate in a manner similar to the regulator R and valve of on the steamsupply pipe N.

At S is a valve connected to a governor, operated by pump D through suitable connections, X, whereby thezamount of steam is always proportioned to the number of revolutions of the pump, and the relative proportion of superheated steam, heated air, and vapor is constantly and uniformly maintained in the vaporizer. This produces perfect combustion and intense heat in the furnace.

Steam from the boiler may passinto the superheater 0, provided it be made of proper dimensions, and the steam and air may pass directly into the vaporizer F if this be sufficiently enlarged. Thecommingledsuperheatedsteam, heated air, and hydrocarbon vapor, or steam and hydrocarbon vapor, or air and hydrocarbon vapor, may be used for heating the furnace A, or by means of pipes P and M for heating the furnace TV, or through pipes P and N H K for heating the boiler B, range D, stove E; or they may be taken to burners, as at B, for lightin The temperature of the commingled vapors at the point of combustion should be at all times sufficient to prevent the vapors from condensing or becoming moist and heavy.

The governors V and construction.

It will be borne in mind, as stated hereto- V may be of ordinary fore, that the heat of the furnace W is to be so regulated that the temperature shall be maintained at or above the boiling-point of the liquid hydrocarbon, but below that of its destructive distillation, so that the liquid shall only be converted into vapor and be taken up bythesteam or airand thoroughly com mingled therewith.

The pressure regulator It and air-forcingdevice D areillustrated in Fig. 5 of the drawings and described in the specification (though indicated by different letters of reference) of the United States Patent No. 241,208, granted to me on the 10th day of May, 1881; but no claims were made in that patent therefor, reference being made therein to the claims-for them preferred by me in the application made herewith.
