APPARATUS FOR HANDLING OIL FOR FUEL.

SPECIFICATION forming part of Letters Eatent No. 537,584, dated April. 16, 1895.

Application filed April 12, 1893| Serial N01 470,066- (No model.)

T0 on whom it may concern.-

Be it known that I, WALTER S. ROCKWELL, of New York, in the. county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Handling Oil for Fuel; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in apparatus for handling oil for fuel purposes, the object being to provide means for regulating the pressure to any desired amount and when set at a certain predetermined point to hold it there without fluctuation thereby producing a perfectly steady fire.

A further object is to provide means for heating the oil to a comparatively high temperature without the possibility of evaporation and loss thereby, and rendering it ready for quick combustion.

A further object is to provide for cleaning and separating the oil from sediment, water or other foreign matter, thereby fitting it for delivery to the fire through a very small open ing without choking.

pearing in section.

A still further object is to carry a small quantity of oil under pressure with the above named advantages and to remove it from the premises entirely and quickly when desirable to do so thereby making it a safe and reliable fuel.

With these ends in view my invention consists in a tank or storagechamber or connected chambers in which a supply of air, oil

and Water is maintained under constant and uniform pressure, the three. elements being confined in a -single chamber or in connected chambers whereby the pressure upon the oil is kept uniform at all times.

The invention, further consists in certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims. I

In the accompanying drawings, Figure 1 is a view in elevation showing the arrangement of the pipes, the tank or storage chamber ap- Fig. 2 is a view in end elevation. Fig. 3 is an enlarged view of the tank; and Fig. 4 is a bottom plan of the tank.

A represents the tank or storage chamber, of which I have shown only one though three could be used to advantage provided they are suitably connected together. This tank is made in the usual manner, of boiler iron with the heads riveted thereto so that the entire tank or chamber is closed except at points where the pipes enter the bottom.

Two pumps B B are secured on the support, which also holds the tank, and at opposite ends thereof, the two being provided so that in case one gets out of order at any time the other will do the work without causing any needless delay. A suction pipe 1 leads from the supply pipe 2 to each pump and a discharge pipe 3 extends from one pump to the other. This discharge pipe 3 has leading from it in a downward direction a pipe 4. Pipe 4. continues on down, preferably having the elbow 5' formed therein, and thence it connects at its lower end with thesupply pipe 2 forming a by-pass for the oil to flow through from the pump after the pressure has reached a certain predetermined point in the tank or storage chamber, as will be explained more fully hereinafter. At-a point above the elbow 5 a branch pipe 6 leads into the bottom of the tank as shown in Fig. 2. In these several pipes the necessary valves are located. as follows:

In pipe 3 there are two valves 7, 7, one between the point where pipe 4 joins pipe 3 and each pump. As only one pump is used at a time of course the valve adjacent to the idle pump is closed and both maybe closed when both pumps are stopped. In the elbow 5 there is another valve, a pressure or regulator valve 8. This latter valve is turned to regulate the pressure under which the oil shall be maintained in the tank or storage chamber A. Still another valve, a check valve 9, is located in pipe 6 this being provided to prevent the oil from flowing back out of the tank, once having been pumped into the latter.

A water pipe 10 connected at one end with a water supply under pressure is preferably connected at the other end with the inner end of pipe 6 as the most convenient place for such connection and in this pipe 10 a valve 11 is provided for regulating the How of water therein or for cutting it off entirely as the case may be. It is also provided with a check valve to prevent the water from flowing out of the tank after having onceentered thelatter. This pipe may be used as a source of pressure upon the oil in event of both pumps being stopped for any reason, and when it is desired to replenish the tank with water.

A waste pipe 13 leading fromthe bottom of the tank into the sewer, is provided for drawing off the contents should occasion require the emptying of the tank. The pipe has a valve 14 therein for opening and closing it.

0 is the pipe whichsupplies. the: burners. Thispipe enters through the bottom ofthe tank or storage. chamber terminating atone, end near the upper end oi the tank and the other end extends to the burners. The pipe is furnished with a valve 16 by means of which the supply of oilto'the. burners may be cut off.

In order to heat the oil as economically as possible the exhauststeam pipe 17 is'carried alongside the supply pipe2 in close proximity thereto so that by the time the oil reaches the tank it has the desired temperature.

Other accessory features such as valves 19, 19, in the suction pipes 1, 1, valve 20 in the supply pipe, steam gage 21, pressure gage-22, thermometer 23, and automatic. self closing gage cocks 24 are provided, but. as. they are common to this variety of apparatus they do not require further description here.

In operation valve 11 is opened in water pipe 10 and the desired quantity of water is allowed to flow into the tank. The engineer need only look at the gage 24: to ascertain when enough water has entered the tank. When the water level has reached the desired point valve 11 is closed. Thevalves'? and 19 on either side of the. operatingpu-mp are now opened, the pump is started and oilis. pumped into the tank and as it is discharged into the bottom of the tank it passes upward through the water, assuming a position over the water and between the water and airspace, owing to its specific gravity being greater than the one and less than the other. continues until the elastic or compressible medium, as air for instanceatthe top is compressed to the degree required to create the desired pressure, the. pressure being regulated by valve 8 which is set. at the proper point beyond which the. valve opens and al-- lows the oil to flow through the by pass and out into the supply pipe. 2 again so that should the consumption at the fires be destopping or varying the speed of the pumpin the least, the valve 8 will automatically relieve the pressure and permit the oil to flow out through the by'-pass just as fast as it is I contain water and {LII elastic 01' 00111 I'GSSldischarged from the pump, and on the other hand the moment the consumption begins again valve 8 automatically readjusts itself and in this way the same pressure is maintained. Of course it is understood that the pressure may be increased at any time by screwing the valve 8 in, or it may be reduced by opening the valve wider as desired.

It will be observed from the drawings (Fig. 1) that the height of the pipe 0 is such that the level of the oil is never much above the open end of the pipe, but this level is kept uniform when the apparatus is in opera tion, that is to say, so long as the pump is supplying: oil or in operation under water pressure, and this provision is made so that in case of leakage, as for instance the result of carelessly leaving a-burner valveopen over night, at. most only a comparatively small quantity of oilcould leakout before thelevel of the oil would drop below the open end of pipe. 0.

Thus, to. recapitulate, it will be seen that I am enabled to regulate the pressure upon the oiland when set at a certain pressure to hold it there without fluctuation, thereby producing'a perfectly steady fire. I am enabled to heat the; oil to a. comparatively high tem- .pera-ture without the possibility of evaporation and loss thereby, expanding it so that as itpasses upward through the water it is entirely freed from foreign mattersuch as sediment, water, &c., and rendered ready for quick combustion through a very small opening withoutchoking; and tinallyI am enabled to. carry a. small quantity of oil under pressure; with the above named advantages, and

to remove it entirely from the premises. by

,simply opening the valve let at any time and permitting the oil and water to flow out.

Having fully described my invention, What i I claim as new, and desire tosecure by Letters i Patent, is-

l. The combination with a tank adapted to receive and hold oil, water and an elastic, or compressible medium, and means for creating a pressure greater than the atmospheric press- I ure-upon the oil and water contained in the tank, of a pipe leading from the tank to the burners for supplying oil to the latter, substantially asset forth.

2. The combination with a tank adapted to ble mediulmand pump for creatingapressure upon the water and oilgreater than the atmospheric pressure, of a pipe leading from the tank to the place where the oil is to be used,

a pipe leading from the pump into the tank, a by-pass leading from this pipe, and a pressure valve in. the by-pass, substantially as set .forth. creased or stopped at any moment without 3. The combination with. atank adapted to containoil, water and an elastic or com pressible medium, of a discharge pipe, a pump, oil pipes leading to and from the pump and a water pipe leading from a water supply un- IIO tier pressure into the tank, substantially as set forth.

4. The combination with a tank adapted to contain air, oil and water, regulating gage and pressure gage, of a pump, for supplying 'oil to the tank, and discharge pipe for oonducting the oil from the tank to the burners, substanstially as set forth.
