SPECIFICATION forming part of Letters Patent No. 495,223, dated April 11, 1893. Application filed July 11, 1892- Serial No. 439,579. (No model.)

To all whom it may concern:

Be it known that I, FREDERIC A. LANE, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Oil-Cans; and I do hereby declare the following, when taken in connection with accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view of the can complete,

Fig. 2, a vertical section of the same; Fig. 3, a vertical central section with the cap removed; Fig. 4, the spindle detached.

This invention relates to an improvement in that class of oilers which are provided with some means for closing the ejector-tube, so as to prevent the escape of oil, such oilers being specially adapted for the pockets of cycles, and other purposes where it is necessary to prevent the accidental escape of oil through the ejector-tube, the object of the invention being to provide the oil-can with means for conducting the oil from the ejector-tube to the desired point, and in a regulated or limited quantity, and the invention consists in the construction as hereinafter described and particularly recited in the claims.

The body A, of the oil-can is preferably made of cylindrical shape, and this is best made from a sheet-metal tube, closed at the bottom. The bottom B, is made from elastic sheet-metal, and of concave-convex shape with the convex surface outside, and so that that convex surface may be depressed to operate as a compressor on the contents of the can, as a means to force ejection. At the upper end of the can a neck C, is attached or made as a permanent part of the can; this neck is constructed with an annular flange D, upon which rests a hard rubber packing E. The neck is tubular, and into the neck the ejector-tube F, is screwed, as shown, so that it may be removed for the purpose of filling the can. The neck projects above the packing-collar E, and is screw-threaded upon its outside.

G, represents a cap, the cavity in which is somewhat deeper than the depth of the projecting ejector-tube, and at its open end is screw-threaded corresponding to the screwthread on the neck, and so that it may be screwed thereon down upon tne packing E, as seen in Fig. 2. Within the cap and at the end of the cavity therein, a flexible plug H, is introduced, to fill that end of the cap, and so as to become stationary therein. This plug is adapted to bear against the end of the ejectortube, and so that when the cap is screwed down, this plug comes to a close bearing upon the endof the ejector-tube, and so as to securely close that end against the possibility of the escape of oil. Any oil which shall work through the screw-thread around the ejector-tube,'as it naturally and unavoidably will do, will pass into the cap, but it cannot escape therefrom because of the pack ing E, upon which the .cap closely fits, so that while possibly the oil'may escape around the ejector-tube, as in all constructions of oil-cans it will do, the oil so escaping .cannot escape from the cap, but will be retained within the cap. The amount of oil so escaping around the ejector-tube is slight, but no matter how slight that escape is, it is desirable to prevent the possibility of contact between the oil so escaping, and surrounding objects, or to prevent its flow onto the outside of the can as it will do in cans where there is no protection of this cap-like character.

By the peculiar construction of the cap and packing,'the oil is prevented from-escaping onto the exterior of the can, so that the soiling of the fingers or articles with which the can may come in contact is avoided.

Within the can a spiral spring I, is arranged, one end bearing upon the elastic bottom B, of the can, and the other end toward the tube end of the can.

J, represents a spindle which is arranged through the ejector-tube, and is of a length considerably greater than the length of the tube; it is best made from wire and tapering. A bend K, is formed in the Wire at a point distant from the end greater than the length of the ejector-tube, and so as to form a shoulder or stop within the can. The spindle is constructed with a tail L, which extends down into the spring, and the spring bears against IOC the shoulder K, on the spindle. When the cap is in place on the can, as seen in Fig. 2, the spindle is forced down through the tube, and compresses the spring, but when the cap is removed, as seen in Fig. 3, the springforces the spindle outward, and so as to project the end of the spindle to a considerable distance beyond the end of the tube. The diameter of the spindle is less than the internal diameter of the tube, so that there will be a practical oil-space within the tube around the spindle when it is so projected, as seen in Fig. 3. The shoulder K, strikes the inner end of the ejector-tube, and so as to arrest the spindle when the desired extent of projection is'produced. The spindle thus projected serves asa-conductor for'the oil,and-so as to lead it to any desired :point, the oil following the spindle :after it leaves the-tube, and so that the quantity ofoil flowing may be readily seen. l o-ejecttheoihthe spring-bottom 'B, is ze'rnployed, the thumb is placed upon that bottom, and pressure is produced accordingly-as more-or less oil is required. Without :the spindle'the pressure upon the bottom would eject a-quantity of oil corresponding'to the passage-through the tube, that passage xis necessarilyof some considerable .extent in'order to prevent its clogging, theresult of the meet such a tube without the spindle is that-a much greaterquantityof oil is generally ejected than is required or de-- .sirab1e,'but by-the introduction of the spindle :the passage through the tube is very considerably "contracted, and the movement of the spindlethrough the tubeas in-the-open-' ing and closing of the cap keeps that passage clear. Again, the spindleis free in the tube when the cap is removed, and if the end of the spindle be applied to the point where'the oil is to be conducted, a slight pressure on thecanwill cause the spindle to move inward,'-and so that an up and down move ment of the can toward and'from the point to beoiled, willncau-sea play on the spindle, and a consequent free but limited flowof oil.

The spindle-does 'not operate in any sense as a valve, and care mustbe taken that the; shoulder which is formed to limit the movement of the spindle shall be such as by no moved or introduced as occasion may require.

I claim- 1. An oil-can of substantially cylindrical shape, and provided with a concave-convex elastic bottom, an ejector tube at the upper end of the camcombined with aspiral spring within the can, a spindle through the ejectortube, of lessrdia'meter than the internal diameter of the *tu'be and constructed with a shoulder within the can,the:length of the spindle fromthe shoulderto its pointbeinggreater than the length of the ejector-tube, the said spiral spring adapted to bear upon the spindle with a tendency :-to force the spindle outward when free so to do,.and a cap overthe ejectontube, and adapted to force :thespindle into the can and close theendofxthe tube, snbstantiallyas described.

2. An oil-can,-the body of which isof substantially cylindrical shape, constructed-with a concavo-convex elastic bottom; the upper end of thecanzprovided with a neck, and an ejector-tube therein, combined with a spindle through said ejector-itube,'of avlength'greater than thelengthof the said tube, but of less diameter than the internal diameterof the tube, thespindle constructed with a shoulder within the'can adapted to limit 'the extent of projection ofthe spindle, and a spiralspring within thee-an adapted to bear upon the said spindlewith a tendency to yieldin-glyforoe it outward through the tube, substantially as described.

Intestimony whereof I have signed this specification in the-presence of two subscribing witnesses.
