SPECIFICATION forming part of Letters Patent No. 268,878, dated December 12, 1882,

Application filed May 26, 1880. (No model.)

To alt whom tt may concern:

Be it known that we, CYPRIEN MARIE TEssIE DU MOTAY, ot' the city of Paris, Republic of France, aiesident of New York, and ED- 5 WARDSTERN, of the city, county, and State ot' New York, have invented a new and useful Process of and Apparatus for Distributing Liquid Fuel in Cities, ot' which the following is a full, true, and exact description, reference io being had to the accompanying drawings.

The object of our inventionis to provide suitable apparatus to carry to every customer in a city a liquid fuel; and it consists generally `in connecting dwelling-houses or other buildings with a double system of pipes,in one of which petroleum is conveyed, and the other of which may contain compressed air or water, as may :be desired, as fully described hereinalter.

OurV invention will be clearly understood zo from the accompanying drawings, in which similar letters refer to similar parts.

Figurel represents generally a view of the central station,designed to take the place of the presentcumbrousand eXpensivegas-works. A

z 5 represents boilerssupplying steam to a suitable engine,B,operating a blower, C. This blower forces'a su ppl y oi' air into the holder D, from `which it passes by the pipe d to the consumer. T represents an elevated oil-tank supplied by 3o the pump P from the lower tank, R. This tank communicates by means of thepipe t with the consumer. The two pipes t and d are preferably arranged as twin pipes, as shown, thereby avoiding the necessity of laying two mains. These pipes may be provided at suitable intervals with automatically closing valves, which will allow the gradual flow of the air or liquid past them, but will close should an escape or leak occur.

Fig. 2 representsan arrangement which ma be used at the consumers station. The pipes d and t are the same as before. c represents one of the automatically-closing valves above referred to. The oil lowing in by the pipe t passes to meter lm, Fig. 2, and thence to vessel n, which acts as a carburetor, as will presently be explained. The petroleum or naphtha entering` this vessel, which is made double,

should preferably the house.

into these sheets of felt, which, acting as siphons, cause it to flow down on the other side.

between,compressioii-blocks h, which maybe adjusted by means of a screw. p represents a pipe, which may lead to the kitchen or other place where combustion is desired, or to a gas, burner. The air entering bythe pipe d passes into the double vesseliz above the body of petroleum k, and so around among the sheets of felt and past the partition r to the pipe p. passage it absorbs from the felt the necessary amount of carbureting material, and so passes to the place of consumption. The amount of petroleum which will be siphoned by sheets g g gis determined by the compression-blocks. Onlythe heavier oils ot' petroleum will be found in the lower part, g, of the chamber a below the compression-blocks, and it Vis important that this be drawn ott and, if not too dense,

returned to the general circulation. This may be done iu many ways. By the one shown a tilting lever, l, is operated by a water-balance, a, which controls a pump, b, suitably arranged with check-Valyes. A continual current of Water is allowed to flow into the bucket c, and when sufcientlias accumulated its weight will cause the pump b to operate, thereby forcing the bodyot' heavy oil which it contains into the general circulating-pipe t ata pointoutside of the house. When the stroke has been completed the bucket c is causedto tip, the Water escapes, and a countenbalance, c, raises the plunger and fills the cylinder again with the heavier oil. The oil in the vessel n may be heated by hot water, taken from the boiler of the house, passing through the chamber fw.

"The full details of the automatic pump apparatus b are not given, since they will be readily supplied by any intelligent mechanic.

The pipe e may be used also to supply air for ventilation of a house; but in this case the air be iiltered before it enters In this bustible gas, of low illuminating-power.

By the means shown the carburetors of'the consumers are au tornatically purged, and theoil which has given off its more volatile constituents increases gradually in density. When it reaches a certain point of density, so that it cannot properly be carried directly into the circulation,this oil is collected either at a main station or at a station placed in some other locality and there distilled. The lighter oils, after being condensed, are then returned to the general circulation, while the heavier products are used either to give light to oil-lamps or as a fuel for 'the steam-boiler at the main station or elsewhere. By-this means all the oil is utilized without waste. Different manufacturies, likewise, which require a low-pressure air-blast, may be supplied from the general circulation d at almost a nominal cost. If it should be desired for heating or illuminating purposes, the air circulation could be replaced by waterlgas, or any other cheap comln case a very high illuminating-power should be desired, oxygen gas could be taken instead of air; but in that case it would be necessary to conduct the gas direct to the burner a through, say, a pipe, e', and cause the stream ot' oxygen gas to impinge on the oil at the burning-point. rThis could be done byl having at each chaudelier a small oil-reservoir with an automatic valve, which would keep it supplied with oil at a constant level, and would he connect-ed to the different burners of the chandelier.' By this method of heating the wasting of fuel is diminished to a minimum, because it is only used when actually needed,and theoil is turned ott' the moment the object is accomplished, Neither smoke, dust, nor ashes, to any material extent, results from this method of utilizing fuel.

A modification of the above systemisshown in Figs. 3 and 4. It and Trepresent the naphtha-tanks, as before. P and P are two pumps suitably operated by steam, one of which forces naphtha into the elevated tank T, the other of which forces water into the elevated tank W. From this tank the water flows through the twin pipe w to the consumer. The arrangement of the apparatus at the consumers sta'- tiou is shown in Fig. 4. The water-power arriving by the pipe w acts upon a small turbine, which operates a blower, M, which tills au air-tank, N. This air-tank is suitably connected with a Valve, V, so that when it is filled thc water is shut off from the turbine. By this means compressed air is supplied at the dwelling to the carburetor n by means ot' waterpower sent through the mains; or if the waterpower can be obtained from the water-works the water-pipe w may be dispensed with. The rest of the apparatus operates as before. Where water-power may be obtained at the dwelling oxygen may be supplied to the burners from the main, and a turbine worked on the premises may operate a blower, from which air is conveyed to the carburetor and to each burner, the oxygen impinging on the carbureted air resulting in abrilliaut flame.

We do not here claim distributing oil from a central supply and burning it in connection with oxygen or its equivalent conducted to the burners, nor the use of oxygen toiucrease the illuminating. and heating power ofthe gas., as these may form the subjects of a separate application for Letters Patent.

What wevclaim as our invention, and desire to secure by Letters Patent, is-

1. In combination with a central reservoir and a series of distributing-pipes conveying liquid fuel to the different houses of a city or town, apparatus arranged in the different houses for vaporizing each a portion of said liquid fuel, and a pump and pipes for returning the heavier portions of said fuel to the general circulation, substantially as set forth.

2. The combination, in a town heating and lighting system, of a central reservoir of liquid fuel, a double series of pipes, one of which supplies the liquid fuel to the different consumers of the town, and the other of which supplies compressed air or gas, and carburetyors at the different places to be heated or lighted, constructed to ca rburet the compressed air so delivered by means ofthe liquid fuel delivered by the fuel-supply pipes, substantially as described.

3. The method of supplying heating or illuminating gas to consumers in a city or town, herein described, which consists in supplying to each house the fuel in a liquid condition from a central source, and then carbureting air delivered in each house by said fuel, substantially as described.
