SPECIFICATION forming part of Letters Patent No. 378,886, dated March 6,1888.

Application tiled September 2, 1887. Serial No. 248,614. (No model.)

To all whom it may concern:

Be it known that I, JOHN S. HOY, a citizen of the United States, residing at Albany, New York, have invented new and useful Improvements in Oil-Cans, of which the following is a specification.

My invention relates to certain new and useful improvements in oil-cans and similar vessels, and particularly'to-that class in which the can is provided with an adjustable (and at the same time removable) pump, by means of which the contents of the can may be extracted and deposited into any other vessel. In this class of cans it is desirable that the pump should be adjustable, so that it may be lifted to bring its spout at different altitudes to permit vessels of varying height to be placed under the same, and that it may also be rotated so as to present the spout in line with different radii for the purposes of convenience. Such pumps are usually introduced into the vessel through a screw-cap Opening in its top and near one edge, and when entirely removed from the can the opening in the top thereof is closed and the can is in condition for transportation.

'Ihe object of my invention is to provide a pump of such construction that in raising the spout to different altitudes the lower end of the pump-barrel shall always be close to the bottom of the can, thus permitting the complete emptying of the can. It also has for its object to avoid the necessity of locating within the can the usual pump-well, which is a disadvantage, in that its presence tends to decrease the capacity of the can and to largely increase the cost of its production.

With these ends in view my invention consists substantially in such features of arrangement, construction, and combinations of parts v as hereinafter specifically claimed.

In order that thoseskilled in the art to which my invention pertains may know how to make and use the same, I will proceed to describe the construction and operation, referring by letters to the accompanying drawings, in Which- Figure l illustrates an ordinary can in vertical section with the pump located therein, the latter shown in elevation, and the dotted lines illustrating the vertical adjustment of Athe same. Fig. 2 is avertical central section, on an increased scale, of the pump and its connections.

Similar letters indicate like parts in both gures.

A represents an ordinary can provided with a suitable bail for handling the same, and having a suitable central opening, B, in the top, provided with ascrew-cap, and having also at or near the edge, or one side of the top, another opening, C, closed while in transportation by a suitable screw-cap, D. This forms the complete can. The pump adapted to be used therein consists of a cylindrical tube, E, provided at its upper end with a spout, F, and furnished with a central sucker-rod, G, and suitable sucker or valve, H, at its lower end. This tube E is usually made sufficiently long to reach to the bottom of the can, and when in place to extend a reasonable distance above the top of the can, and it is provided with a short cylindrical sleeve, I, the upper end of which terminates in a screw-cap similar to the screw-cap D, in order that when the sleeve I is introduced through the opening C it may be iirmly secured in place in an obvious manner.

The pump-tube E is roughened on opposite sides, as seen at a b, in order that sufficient friction may exist between the tube E and the sleeve I to maintain the tube at any altitude to which it may be lifted.

The lower end of the tube E has secured to it an extension consisting of a flexible tube, J, which I make, preferably, of leather, which tube, it Will be readily observed, is adapted to lie upon the bottom of the can irrespective of the altitude to which the spout of the pump may be lifted, and thus be in position to reach the oil in the can,'and by means of which the final contents of the can may be extracted. In forder that this extension-tube J shall not collapse during the pumping operation, I provide it with a spirally-coiled wire core, K, as clearly shown at Fig. 2. I do not of course wish to be confined to the specific details of construction-such, for instance, as the roughened or serrated surfaces on the sides of the tube to secure the necessary friction-for in lieu thereof any suitable packing may be ernployed between the pump-tube and its sleeve,

IOO

and in some instances it may be desirable to dispense with the sleeve entirely7 and in lieu thereof to furnish the opening through which the pump-tube enters the can with a packing.

The iexible tube at the lower end of the tube E is secured in place by any suitable fastening device-such, for instance, as a wire Wrapping.

Vhat I claim as new7 and desire to secure by Letters Patent, is-

l. In a pump for oil-cans and similar vessels, the combination, with the can having opening C surrounded by a threaded flange, of the pump-tube having a suitable sucker-rod and sucker and provided with a short cylindrical sleeve, I, the upper end of which terminates in a screw-cap adapted to iit the threaded ange, the sleeve being` adapted to secure the pump-tube to any altitude to which it may be brought, substantially as described.

2. In a pump for oil-cans and similar vessels, the combination, with the can having opening C, of the pump-tube having a suitable suckerrod and sucker and provided With the sleeve I, terminating at its top in a screw-cap, and the iieXible extension attached to said pumptube, provided with a spirallycoilcd Wire or core, substantially as described.

In testimony whereofI have hereunto set my hand in the presence of two subscribing Witncsses.

JOHN S. HOY.
