OIL-CAN.

SPECIFICATION forming part of Letters Patent N 0. 558,207, dated April 14, 1896.

Serial No. 571,602. (No model.)

To all whom t may concern:

Beit known that I, CHARLEs W. Peocron, a citizen of the United States, residing at Lake Forest, in the county of Lake and State of lilinois, have invented certain new and useful Improvements in Oil-Oans, of which the following is a specification, reference being had Figure l is a central vertical section through an oil-can embodying my improvements, and Fig. 2 is a detail illustrating a modification.

This invention relates to cans containing oil from which from time to time a supplyis to be drawn for filling lamps, oil-stoves, or other devices, and has for its object to equip such a can with devices whereby the contents can be forced out through a suitable discharge-tube by means of atmospheric pressure and the iiow instantly stopped, when desired, by shutting off such pressure. I attain this object by the construction of devices, as shown and ashereinafter fully described.

That which l regard as new will be set forth in the claims. l

In the drawings, a indicates an oilcan, which may be of any suitable size and construction.

b indicates an ordinary capscrewed upon the usual nozzle on the top of the can.

c indicates a short tube passing through the cap b and soldered or otherwise firmly affixed to said cap. This tube is closed at its lower end, and near such end, in the wall of the tube, are a number of small openingsd.

e is another tube of sufficiently less diameter than the tube c to enable it to fit withinV and be movable in said tube c. This tube e is open at both its ends.

f is a coiled spring encircling said tubes c and e and having its ends bearing against shoulders g g', secured, respectively, to the tubes c and e.

h is a dischargepipe, the upper end of which is curved to better discharge into a vessel and the lower end is extended to near the bottom of the can. This tube h also passes through the cap b, and, like the tube c, is firmly soldered or otherwise secured to said cap. The joints formed by the tubes passing through the cap are to be made air-tight.

For Vstrengthening purposes the two tubes c and 7L are soldered or otherwise secured to gether, as at 'L'.

The operation is as follows: The parts being in the position shown in Fig. l and it being desired to discharge some of the contents into a lamp, an oil-stove, or some other vessel, air is forced into the can, preferably by blowing with the mouth into the upper end of the tube e. The air passes through the tubes e and c and through the openings d into the can. 'Vl/Then a sufficient amount of air has thus been forced into the can to produce the required pressure, oil will flow from the discharge-tube 7L. As soon as the required amount of pressure is had to start the flow of oil through the tube 7L the blowing of air through the tubes e and c is to be discontinued, and simultaneously therewith the tube e is to be forced down Y by the operator against a coinpressible Washer located in the bottom of the tube c. This will bring the tube 'e opposite all of the openings d and thus preventthe escape of air from the can. The tube e is to be held down opposite the openings cl until the desired amount of oil has been drawn off. The tube e is then to be released by the operator, when, through the action of the coiled spring f, such tube ewillbe returned to its normal position and the air in the can allowed to escape by means of the openings d and tubes c and e. The pressure being thus removed from the oil the flow through the tube 7L will cease, and by the suction created the tube 7L will be given a siphonic action and waste of oil prevented.

In the modification illustrated the tube c is not perforated and is not closed at its lower end. In this construction the inner tube c is adapted to be pushed past the end of the outer tube c and against a cork or other suitable stop Z, secured to the discharge-tube h. Vhen so pressed down, it will eifectually prevent the escape of air from the can, and when the downward pressure on the tube e is released air from the can will escape through the open lower end of such tube, thus shutting off the IOO and one that can be readily removed from a can to permit the can to be filled or cleaned. NVhen removed from the can, there are no openings left other than the usual lillingopening, Which can be closed Ywith the ordinary screw-cap.

That which I claim as my invention, and desire to secure by Letters Patent, is

l. The combination with an oil-can provided With a dischargentube, of a stationary tube secured to said can one end of which projects Within the can, a longitudinallymovable tube arranged within said stationary tube, means for preventing the escape of air from the can when the longitudinally-movable tube is forced down, and means for returning to and normally holding said longitudinally-movable tube in its elevated or normal position, substantially as described.

2. The combination With an oil-can provided with a discharge-tube, of a stationary tube secured to said can and projecting thereinto,va stopl secured to the discharge-tube below the stationary tube, a longitudinallymovable tube arranged Within the stationary tube and adapted when forced down to contact With the stop and prevent the escape of air from the can, and means for returning said longitudinally-movable tube to its elevated or normal position, substantially as described.

CHARLES V. PROCTOR.
