- Application filed June 25, 1903. Serial No. 163,054. (No model.) I

To aZZ whom it mag concern.-

Be it known that I, Dosrnn H. MosrnLLER,a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Systems of Supplying Oil under Water-Pressure, of which the following is a specification.

My invention relates to an improved system of piping for supplying oil under water-pressure to oil-burners for use in ranges, furnaces,

or the like.

' The'object -of my invention is to provide such a system by means of which theoil can be replenished without interfering-in any way with the pressure or with the supply ofoil to the rangefthus enabling the-fire to continue undiminished. v

"Afurther important improvementis to provide means whereby the air which is removed from the tank in filling it with oil and which has a strong and unpleasant odor can be conducted in a convenient manner to the sewer, so that the odor will not escape into the building.

A further important feature of my invention is to provide means whereby the reservoirs for the oil may be inclosed in brickwork or the like protective material, while at the same time permitting free control of the 'oil and water in the tanks and enabling'at all oil-supply pipe, which may extend through. .the sidewalk, and is provided at the top with a a coupling 2 for the purpose of connection with the oil-wagon to fill the tank with oil.

3 represents the oil-tanks, which are provided in duplicate, so that one can be used while the other is being filled. Directly to said tanks lead pipes 4, which extend upward and then horizontally forward and are connected near their frontend with vertical'pipes 5, one of which is connected directly with the oil-supply pipe 1 and the other indirectly by means of a horizontal pipe 6. Stop-cocks 7 are interposed in the short vertical pipes, so as to allow of the filling ofsaidpipes from said tanks as may be desired. Said'oil-supply pipes are continued forward and connect with the feed-pipe 8, which leads to the range or furnace or other heating medium. In the short forwardly-extending ends are stop-cocks 9 for shutting off either or'b oth' of said tanks from the range or furnace.

10 represents the water-supply pipe, which is fed with water from the city main or any other source of water under pressure. If necessary, a cistern may be provided at a suitable height abovethe water-supply pipe to give the desired pressure. Said water-supply pipe has a CllGClGVLlVB.11131161811'1. In order alsoto insure a supply of water underpres- 'sure even in case of the said water being turned off temporarily, Iprovide an auxiliary water and compressed-air tank 12, containing a sufficient supply of water tofeed either of the tanks 3 with-water and also a supply of compressed air providing the desired pressure, which compressed air may be obtained by means of a small pump 13, attached to said compressed-air tank. It will readily be seen that ifthe usual supply of pressure-water is cut off the auxiliary-tank maybe used to furnish the desired pressure by opening the cook .14 below said tank.

The pressure-water flows through the two pipes 15, controlled by stop-cocks 16, into the vertical pipes 17, which extend downward and then horizontally to a point underneath the tanks and then into said tanks. By a suitable choice of the stop-cocks 16 the water can be caused to enter either tankat will. Above gages 21, connected to pipes 22, which are connected to the tanks at the top and at a point near the bottom, as shown.

I also provide means for allowing of. a vent The operation of the apparatus is as follows: I Supposing that one tank is full of oil and the other tank is being exhausted and it isnow' desired to replenish the latter and to com-.

mence using the full tank for. the, purpose-of feeding oil tothe range or furnace, the first step is to admit thewater-pressure to the full tank by opening the corresponding stop-cock 16, if it is not already open. The next step is to simultaneously close the stop-cock 9 in the feed-pipe from the empty tank andopen the stop-cock 9 in the feed-pipe from the full tank, thus maintaining the supply of oil un derpressure to the range or furnace. Now proceeding to fill the empty tankwith oil, this is accomplished as-follows: First thewaterpressure is shut off from the empty tank by closingthe stop-cock l6. Next the discharge.- pipe from said empty tank isopened by open.- ing;the'stop-cock 18. This allows thewater to run out of the empty tank into the sewer. While the water is running out, oil maybe admitted to the empty tank through the oilsupply pipe 1 by. means of the pipes 4 5, the stop-cock being opened for. that purpose.

Also the stop-cock 26, which controls the.

air-escape pipe, is opened toa-llow the air to escape into the discharge-conduit and thence to the sewer, as already explained. The water runs out of the tank, and byinspection of the gage 28 it isascertainedwhen thewater has been completely removed from the tank. Then the stop-cock 18 is closed to prevent any further escape of oil. Oil is still supplied to the tank which is being filled until a sufficient quantity has been supplied thereto, care being taken that no oil remainsin the pipes above the tank. The stop-cock 7 is then closed. Pressure-water is now admitted by opening the cook 16. This immediatelyforces any air from the top of the tank through the air-escape pipe, and the gage 27 in this pipe is watched until it is seen that oil begins to flow therethrough, so that no air is left in the tank, this being extremely important to avoid, for any compressed air left in the tank would blow the fire out. The stop-cock 26 in the air-escape pipe is now closed, and the tank is ready for further use when required.

In some places there are municipal and um? derwriters regulations requiring the tanks to be inclosedas, for instance, with a brick wall of a certain thickness around and above the tanks; It will be seen that my improved system is well adapted for compliance with such regulations.- The pipes are brought from the tanks through the wall, (shown at 30,) and the gages are inclosed in a recess orbox 31, formed in the front of the wall, having an iron door or shutter 32, as shown, which may be opened for the purpose of inspection of the gages at any time. It will also readily be seeuthat this system allows ofthe tanks beground, if desired, the pipes being then continued to a considerable height for inspection and operation and suitable-means being protanks. 'While I have-herein shown a duplicate system of tanks, there are important features of 'my inventionas, for instance, theescape of the air from the tank lnto the sewerwh1ch are not confined to-a duplicate system, but can also be'used in connection with a single tank. Iclaim-- 1. In an apparatus of the character described,

- vided for ascertaining the condition ofthe the combination'of a pair of'oil-tanks, a dissaid tanks for discharging water therefrom, a vent-pipe leading from the topof each tank charge-pipe connected. with the bottoms of and connected to said discharge-pi pe, whereby the noxious gases from said tanks are carried off by said discharge-pipe, and sight-gages in said connections, substantially as described.

2. In an apparatus of the character described,

. the combination of a pair of oil-tanks, a discharge-pipe connected with the bottoms of said tanks for discharging water therefrom,

a Vent-pipe leading from the top of each tank and connectedto said discharge-pipe, whereby I ing air into .the upper portion'of' said latter tank, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
