MEAsURlNe OIL=TANK- SPECIFICATION forming part of Letters Patent No. 361,828, dated April 26, 1887.

Application filed January 10, 1887. Serial No. 223,883. l (No model.)

or other places where small quantities are drawn; and the object of the invention is to provide a receptacle from which no gaseous odors will be emitted, which is air-tight, and

fronr which predetermined quantities of oil maybe drawn, whereby no waste occurs and evaporation obviated.

Although we herein describe our invention for the reception of oil, yet we do not limit our invention to that use, but hold it to be useful and as equally adapted for the reception of other liquids, as will hereinafter appear.

With these objects in view our invention consists in certain features of construction hereinafter described, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a front elevation of a receptacle constructed in accordance with our invention. Fig. 2 is a transverse section onthe line y y of Fig. l. Fig. 3 is a vertical section on the line :v x of Fig. l, showing the faucet closed; and Fig. 4 is asimilar view, the faucets being opened to permit the withdrawal of a predetermined quantity of oil.

Like letters of reference indicate like parts in all the figures of the drawings. K

A, in this instance, represents an air-tight rectangular case, which is provided with a cover, A', having an opening provided with a plug, A2, the case being mounted upon suitable legs, A3. The case A may be made of any desirable or'convenieut form or material, in which instance certain accessories contained therein may also be constructed to conform to the interior thereof.

Within the case and located at suitable points are a series of measuring-tanks, B B B2 B3, or there maybe more or less, as desired.

At the front of the case, extending through the wall thereof and connecting the tanks or measures B B B2 B3 with the exterior, are a series of three way faucets, C C G2 C3, and a series of three-way air vents or faucets or cocks, D D D2 D3.

Extending above the series of faucets is an oil-supply pipe, E, which is connected to said faucets by a series of 'lf-couplings, E, and with the interior of the casev by a pipe, E2; and above the series of air-cocks there extends a similar pipe, F, connected to each of said cocks by ordinary Tcouplings,.F, at about the center of which is a pipe, F2, leading to a 4tube,(in'this instance glass,) F2, mounted upon the outside of the case, and communicating at its top with the interior ofthe case.

Both the faucets and cocks are provided with three-way valves, which are operated by ordinary7 handles, said valves being so constructed that when those of the faucets are down the liquid in the measuring-tanks cannetpass out through the faucet; but communication is opened between the measuring-tank and the case through the pipesE and E2. The construction of the aircock is different,in that the operating-handle when down or in a perpendicular position opens communication between the measuring-tank and the exterior air, and when turned up opens communication between the measuring-tanks and interior of the case, near its top, through the medium of the pipe F2 and the tube F3.

The operating-handles of the series of cocks and faucets are connected by a rod, G, pivoted in the ends of each of the operatinghandles-that is, of the cocks and faucets. By means of this connection it will be seen that when the operating-handle of one of the faucets is turned a quartenway up it acts to open to which itis connected and the exterior, thus allowing any liquid contained in the tank to pass through the faucet into any receptacle thereunder, (see Fig. 4.,) and at the same time the operation of the rod G upon the operatinghandle of the cock will cause it to turn down, opening up communication between the interior of the measuring-tank and the outer air, thus allowing air to pass therethrough into the tank and take the place of the amount ofliquid communication between the measuring-tank l IOO withdrawn through the faucet. By a reversal of this operation-namely, turning the handle down, as shown in Fig. 3-communication will be opened between the measuring-tank and the interior of the case through the medium of the pipes E and E?, thus allowing oil or other liquid contained in the case, which has been previously filled through the hole in its top, to pass through the pipe E2 into the transverse pipe E and down into any of the tanks that may have been emptied. Thus at all times are the measuring-tanks kept filled.

Eachof the tanks holds a certain quantity of liquid-in this instance from a pint to five gallons; and for the purpose of further illustration we will take, for instance, the one containing a gallon, as indicatedin the drawings. Oil having passed from the case into the measuring-tanks, by throwing the operating-handle of the faucet C2 up, as shown in Fig. 4, all liquid (one gallon) contained therein will ow out of the measuring-tank into any receptacle for its reception, the space vacated by the oil being filled by air passing from the outside through the air-cock into the receptacle. Now, byturning theoperating-handledown,asshown in Fig. 3, the liquid will pass from the case through the pipe E2 down into the faucet and into the measuring-tank and will continue to flow until the same shall have been filled, the air contained in said ytank being forced out throughtheair-cockinto the pipes F13, through the tube F3, and into the casing at its top, and thus fill the space vacated by the oil which has gone to lill the tank just emptied, and serving as a Vent.

Thus it will be seen that no evaporation of the liquid can take place, that no waste can occur, and that by reason of the case being air-tight there is less danger of fire, and also all odors are contained in the tank and cannot escape, as all air coming in contact with the liquid is afterward forced back in the case. In other words, there is no outflow of air from either the case or measures.

We do not limit our invention to the exact construction herein shown and described, but hold that we may vary the same in any manner and to any extent within the scope of mechanical skill.

Having thus fully described our invention and its operation, what we claim isl. In a liquid-receptacle, the combination of an air-tight case having measuring-tanks with faucets and air-cocks connected therewith and with each other, whereby by drawing liquid from the tank through the faucet said faucet will operate the cock so as to admit air to the tank, substantially as specified.

2. In aliquid-receptacle, the combination of y an air-tight case with measuring-tanks provided with faucets and air cocks connected therewith and with each other, and of a pipe leading from the case to the faucet and a pipe or tube from the air-cock .to the interior of thev 6 5 pacities with faucets and air-cocks connected therewith and air and liquid pipes leading from the case to the tank, substantially as specified.

4. In a liquid-receptacle, thecombinationof an air-tight case having measuring-*tanks of different capacities with faucets and air-cocks SQ connected therewith and with each other and air and liquid pipes leading from the case to the tanks, wherebywhen the faucets are open liquid will be emitted from the tanks and air admitted thereto and when ,closed air will emitted from the tanks to the case and liquid from the case to the tanks, substantially as specified.

5. In aliquid-receptacle, the combination of an airtight case provided with measuring- 9o tanks having air-cocks and faucets connected therewith and with each other, said cocks and faucets being provided with three-way valves, a pipe connecting theinterior of the case with the faucets and tanks, and a the interior of the case with the air-cocks and tanks, substantially as specified. v

6. The combination of the case A, having the cover A, apertured and provided with aF plug, of the measuring-tanks B B B2 B3, havroo ing the faucets C C C2 C3, and the air-cocks D D D2 D3, connected by the rod G and with the pipes E2, F2, and F3, substantiall y as specified.

7. The combination of the case A, having the tanks B B B2 B3, with the faucets C C C2 r Cs and cocks D DD2 D3, the operating-handles of which are connected by the connectingrod G, and with the branch pipes F, having the T- couplings F', and the branch pipes E, having the T-couplings E and the pipes E2, F2, and rio F3, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
