OIL-CAN.

SPECIFICATION forming part of Letters Patent N 0. 653,499, dated July 10, 1900.

Application filed February l, 1900. Serial No. 3,566. (No model.) 1

To all whom it may concern:

Be it known that I, WESLEY BLANCHA'RD, a citizen of the United States, residing in the city of Lewiston,-in the county of Androscoggin and State of Maine, have invented certain new and useful Improvements in Oil-Cans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to liquid cans or other containers, and it has referenceparticularly to that class of such containers usually employed for dispensing oil, in which means for discharging the cans of their contents is comprised in each can as a permanent portion of its individual structure.

The object of the invention is to provide a can or container of the character above particularly referred to with a pumping apparatus embodying the qualities of convenience in operation, simplicity and durability in construction, and ability to quickly draw off the desired quantity of liquid and to also practically drain the can completely of its contents, at the same time preserving in the structure of the can as a Whole simplicity and compactness. v

The invention consists in the improved liquid can or container and in the combination and arrangement of its various parts, substantially as will be hereinafter pointed out,

and finally embodied in the clauses of the claim.

Referring to the accompanying drawings,

in which corresponding letters ofreference indicate like parts, Figure 1 is a vertical sectional view of my improved can. Fig. 2 is an enlarged vertical sectional view of the upper portion of said can, a portion of the discharge -pipe being also shown in section. Fig. 3 is aview in elevation, slightly enlarged, of that portion of the can which comprises the pumping apparatus proper. Fig. 4 is a vertical sectional view on the line 00 a: in Fig. 3; and Fig. 5 is atop plan View of the pump proper, a slight modification being presented.

In said drawings, a designates the can,

and b designates the cover thereof, said can provided with a threaded'bushing d, affording a filling-orifice, and onto which is screwed a cap 6, which is provided with a "central orifice f, the function of which will be hereinafter set forth. It should be remarked that the bushing is provided with ducts'g for permitting any liquid that may drop or collect on the cover to find its way into the can.-

In the can, and preferably close in the corner formed by its side and bottom Walls, is arranged a casing h. This casing incloses two chambers t'and j, the former being pref: erably substantially circular and the latter being of any suitable shape, but preferably being substantially rectangular, and having its communication with the chamber-i, dis posed approximately tangentially with reference to the same. This construction is best produced by employing two flat pieces of metal as the top and bottom walls and Z, respectively, of the casing and a single piece of similar material m, shaped, as best shown in Fig. 5, and soldered between them. The communication between the two chambers should be as wide as is the chamber j itself, and in order to render it as unobstructed as possible theportion not the wall m forms a tangent of the circular portion of said wall, being approximately straight. The casing is secured to the side wall of the can and close to the bottom wall thereof preferably by soldering it in place. In its bottom wall l'the casing has a central opening 0.

' This opening is bridged by a plate 19, in which is stepped a vertical shaft q, having bearings near its upper end in the top wall of the casing and {also in a plater, secured upon the same. It should be remarked that the opening 0 is preferably covered'by a wire-gauze s.

t is a vertical spindle that is j ournaled near its upper end in a bushing u in the cover of the can (said spindle therefore protruding from the can at" its upper end) and that is stepped at its lower end, as at '0, in the plate 1". The free or protruding end of the spindle is bent into the shape of a crank w, and it carries a revoluble knob y.

z and of respectively designate an intermeshing'gear and pinion, the former secured upon the lower end of the spindle t and the latter on the upper end of the shaft g. It should be remarked that the diameter of the gear is considerably greater than that of the pinion, so that the rotation of the shaft will be multiplied.

b designates a flat blade or propeller, which is soldered or otherwise secured to the shaft (1 near its central portion, being arranged vertically in the chamber 2 and approximately fitting the same.

0' designates the discharge-pipe for the can. This pipe comprises two telescoped tubes d e, the latter communicating with the chamberj of the casing through an opening f, formed in the top wall thereof, and the former being provided at its upper end with an enlargement or knob g and with a communicating spout or nozzle h and projecting through the cover of the can. This spout or nozzle has its free end bent downwardly, as shown in Fig. 1, and it reaches far enough so that the extremity of the nozzle may be projected into the aperturefof the cap e when the tube d has been turned to the proper position and depressed.

t" designates a sleeve which surrounds the tube (2' and projects through the cover, its upper edge being turned over and soldered to the can, so as to make a tight joint. The tube d is movable loosely in the sleeve. The function of the sleeve 2" is to prevent the liquid being slopped out of the can where the tube projects through its cover.

In the slight modification of my invention which Fig. 5 presents the blade or propeller instead of being perfectly flat, has its free end curved slightly in opposite directions. The convex face of the end of each blade projects in the direction in which the plate is adapted to turn, as shown by the arrow in the figure referred to.

In operation the tube (1 being elevated and the nozzle being swung around into the position shown in dotted lines, so as to bring its discharge end over the receptacle to receive the liquid to be pumped out of the can a, the spindle t is rotated by means of its crank 10, thus rapidly rotating the shaft q and the blade it carries. As the blade is rotated it produces a centrifugal action of the liquid in the casing and forces the same in a continuous stream or flow from the chamber z' to the chamber i and thence out through the pipe 0, fresh supplies of liquid constantly flowing into the chamber '6 through the opening in the bottom wall thereof. It is preferred not only that the port of communication between the two chambers i andj be in a line of centrifugal force of the propeller but that the side walls of the chamber j (which I have indicated by the reference characters j and j as well as, preferably, its top and bottom walls be substantially parallel to said line. Then as the liquid is thrown off by the propeller its course not only into but through the chamber will be entirely free and unobstructed and there will be no tendency toward the production of eddies: It is this particular arrangement of parts here involved which advantageously differentiates my invention from analogous apparatus of the prior art. By curving the ends of the blade in the manner above set forth, moreover, the centrifugal action is greatly augmented and so the flow through the casing is increased, the pump being rendered to this extent even more powerful.

When the can is out of use, the nozzle may be turned back into its original position, so as to project its extremity down through the aperturefin order that the liquid dripping therefrom may fall into the can.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination of a can-or other similar container for liquids, a casing arranged in said can, said casing comprising two communicating chambers, a propeller arranged in one of said chambers, said chamber having an opening communicating with the can and disposed in the axial line of the propeller, means for rotating said propeller, and a discharge-pipe communicating with the other chamber and extending out of the can, said chambers having their port of communication arranged approximatelyin theline of centrifugal force of the propeller, and the propeller having its extremity or extremities bent reversely to the direction of rotation thereof, substantially as described.

2. The combination of a can or other similar container for liquids, a casing arranged in said can, said casing comprising two communicating chambers and one of said chambers having an opening in its bottom wall affordin g communication with the can, a plate bridging said opening, another plate upon the top of said casing, a shaft journaled in said plates and extending through said chamber, a propeller in said chamber and carried by the shaft, a spindle journaled in the can and stepped in said last-named plate and havingacrank,operative connection between said spindle and the shaft, and a discharge-pipe connected to the other chamber and extending out of the can, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 30th day of January, 1900.

WESLEY BLANCIIARD.
