SELF-MEASURING OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 248,956, dated November 1, 1881.

Application tiled March 14, 1881.

To all whom it may concern Be it known that I, THOMAS SCANTLIN, ot' Evansville, Vanderburg county, Indiana, have invented certain new and useful 'Improvements in Self-Measuring Oil-Gans, of which the following is a specification.

This is an improvement on those tanks seen in the patents granted to me October 11,1875, and May 16, 1876; and the present invention comprises the following novel features: first, an elevated measure-receptacle secured on top of the can or tank, and provided with discharge-faucets, which faucets are so disposed as to allow the drippings therefrom to run directly into the sink of the tank or reservoir, said sink being so arranged as to form part of the upper head of the can; second, a novel construction ot' drip-receiving cup and pit located in the sink; third, a novel construction of the apparatus whereby the portion of thel tank in rear of and above the floor of the sink is made available for holding oil; fourth, arranging the overflow from the measure-receptacle so as to discharge directlyinto the floattube.

In the annexed drawings, Figure 1 is a front elevation of an oil-tank embodying my improvements, the oat-tube and a portion of the elevated measure-receptacle being sectioned. Fig. 2 is a vertical section of the tank, taken in the plane of the pump, the slip-pipe being shown applied to a faucet of the measure-receptacle, and discharging into a keg outside of said tank. Fig. 3 is a plan of the tank,the sink of the same being shaded. Fig. 4 is an enlarged longitudinal section of the measurereceptacle. Fig. 5 is an enlarged axial section of thedrip-cup and pit. Fig. 6 is a vertical section of the sliding fulcruin of the pumphandle.

The tank or reservoirA, which is preferably cylindrical and of any desired capacity, is provided at top with a customary segmentalsink, B, the floor of which is securely soldered to the wall of said tank, so as to effectually prevent the escape of oil from the latter. The

back wall, l), of this sink is about vertical,and its upper edge is soldered to the top plate, C, of the tank, by which arrangement the segmental portion D of said tank, located above the door of the sink and in the rear of its wall b, is rendered available for containing oil7 there- (No model.)

that discharges the oil into a tilting trough, J,

which trough, together with its rodj, cone K, and cap L, being the saine as seen in my patent of May 16, i876, needs no further description in this specification.

f, g, and IL are the respective discharge-faucets of the aforesaid measures.

The rst measure, H, receives the supply of ol through a pipe, m, leading from an ordinary lifting force-pump, M, fitted vertically within the tank and near the rear wall of the latter. This pump has a suction pipe, N, which, after passing through the side of the tank, has an external cock or valve, n. Furthermore, said pump has an internal valve or faucet, O, operated by an external handle, o, this valve being applied either to the suction pipeN or at either side or rear ot' the pump, as may be most desirable. The pump is operated by an ordinary handle or lever, P, pivoted at p to a fulcruin-block, R, adapted to slide within the parallelflanges orotherguides s s of a plate, S, attached to the top O of the tank.

Fitted within the tank is a cylinder or other tube, T, having one or more openings, t, to admit oil, and ,being traversed with a suitable float, U, having a rod, u, and pointer u', which latter -trarels along a fixed scale or staff, V. The oil overflowing from the measures F GH runs into this tube throughaliole, c, in the top plate, C, of the tank. g

W is a screw-threaded cap, whose removal permits the tank to be completely emptied when turned over on its side.

Soldered within the sink B is a conical pit., X, open at top and having a lipped inlet, x, said pit being adapted to receive a closely-f1tting removable cup, Y, the upper edge of which snaps under the lip x. This pit and in- IOC closed cup may be covered with a lid, x', as seen in Figs. 2 and 3.

Z is the slip-pipe for conducting oil from either of the faucets f, g, or h into a keg or large can, Q, located outside of the tank A. (See Fig. 2.)

To fill the tank or reservoir A the internal cock, O, is closed, the external one, n, opened, and a hose or other tube is then coupled to the outer end of suction-piperN and inserted in the barrel or other source of supply from whence the oil is to be drawn. .Pump M is then operated, tlierehy drawing the oil from the barrel and forcing it into the rst measure, H, from whence the iluid runs into the central compartment, Gr, thence into the last chamber, F, and finally out through the overiow I. The oil then descends through the opening c into the index-tube T, and runs through the holes t in the latter directly into the tank A, which is tilled completely full, the pointer u indicating on the scale V the very momentwhen the fluid has reached as high as the plate C, and showing the exact contents of said tank, either in gallons or otherwise. The outer cock, u, is now closed, the hose dctached, and the inner valve, O, opened, so as to allow the pump to draw directly from tank A.

As the receptacle E is herinetically closed, it is apparent the oil in the measures F G H will not evaporate, and, consequently, when a limited amount of oil is needed-say two or three quarts-the proper faucet is opened and the uid runs directly into the customers can, any drippingr from said faucet falling inio the sink B and at once iiowing into the cup Y of pit X. After these measures F Gr H have been emptied, they must be again filled by the pump M, and as soon as they are thus charged the oil overflows at the wasteway I and depresses the tilting trough J, so as to elevate cap L, as seen in Fig. 4, and thereby afford ocular proof that said chambers are all full. When the pump is stopped the accumulated oil in the trough J gradually runs ont through the hole j', and allows said trough to assume its normal position, which act is indicated by the cap L, descending and resting on the cone K. (See Fig. 1.)

It' at any time it should be desired to till a large can or cask, Q, the slip-pipe Z is applied to either one of the faucets ot' receptacle E, and the pump is set in motion, the falling of float U indicating when the desired quantity of oil has been discharged from the reservoir A.

Evidently all the oil delivered from my tank must tlrst be raised to the elevated measures; but this additional lit't is not felt, owing to the peculiar arrangement of the pump-lever fulcrum, the block or bearing of which, R, is adapted to play freely in a horizontal path between the guides s .5', thereby confining the piston-rod to a vertical plane, and enabling me to dispense with the customary links, slides, parallel bars, and other complicated and expensive devices heretofore employed for operatingthepistonArodsofoil-tankpumps. Therefore, as the handle I? is raised and lowered, said block reciprocates within these guides, tlius reducing the friction to a minimum and iuore than compensating for the slight additional lift ofthe oil.

When the cup Y has been filled with dripped oil the lid ai can be removed from the pit X, the cup lifted therefrom, and its contents poured back into the can at W, which removal of said cup may be facilitated by soldering a bar or handle athwart the same.

I have described the oil-elevating device M as a force-pump because it has to raise the fluid above its own level; but it is evident an ordinary lifting-pump will perform tliesame duty, provided the lit'tingpump is carried up to the top of receptacle E, as indicated by dotted lines in Fig. 2. As this construction, however, would necessitate a corresponding elevation ofthe pump-handle, some inconvenience might result therefrom.

I claim as my invention- 1. The combination, in an oil-tank, of sink B, elevated receptacle E, and inclosed communicating chambers F, having discharge-faucets f, arranged and adapted to operate asherein described.

2. The pit X, located in the sink B, and having an inlet, ai, and closely-fitting cup Y, as set forth.

3. The tank A, provided at its upper end with a segmental chamber, D, and a sink, B, which latter has an iinperforate door, as herein described, and for the purpose set forth.

4. In combination with the elevated measurereceptacle E and float-tube T t, the top plate, C, having an opening, c, communicating with said tube, for the purpose herein described.

In testimony ot' which invention I hereunto set my hand.

THOMAS SCANTLIN.
