OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 537,888, dated April 23, 189 5.

Application filed January 21,1895. Serial No. 535,649. (No model.)

enlarged View in vertical section through the cap, spout and neck of the can; Fig. 3, a detached view on the same scale of the packing; Fig. 4, a similar view on the same scale,

of the clearing-pin; Fig. 5, a sectional view on the line ab of Fig. 2.

My invention relates to an improvement in that class of pocket or portable oil-cans in which the can is provided with a removable cap fitting over its spout for-the protection of the same, and furnished with a packing or plug located within the outer end of the cap, and engagedby the outer end of the spout for sealing the same against the escape of oil when the can is being carried about. As

heretofore constructed cans of this type have been objectionable on account of the liability of the thin edges of the metal of which the spouts are formed, to out into the packing and disintegrate the same, and cause leakage, and also on account of the liability of the fragments of packing thus removed, to get into the spout, and clog the same.

The object of my present invention is to overcome the objections above recited, and to produce at a low cost for manufacture, a can having a packing which is not only durable, but also extremely effective.

A further object of my invention is to provide for the perpetual clearance of the spout.

With these ends in view, my invention consists in the combination with the spout and can of an oil-can, of a rubber packing located within the closed outer end of the cap, and constructed with a central, inwardly opening passage, the walls of which continuously engage with the exterior surface'of the spout near the end thereof.

.My invention further consists in the combination with the spout and cap of an oil-can, of a packing located within the outer end of the cap, and having an inwardly opening, central, longitudinal passage, shaped to continuously engage with the exterior surface of the spout near the outer end thereof, and forced inward for such engagement, and held in place within the cap bya circumferential, 6o inwardly extending bead formed therein.

My invention further consists in the combination with the cap and spout of an oil-can, of a packing located within the closed outer end of the cap, and havingan inwardly openmg, central, longitudinal passage for the reception of the outer end of the spout, the ex- .terior surface of which it continuously engages, and a clearing-pin adapted to enter the outer end of the spout, and constructed with a head located within the extreme inner end of the said passage, and held in place by the closing of the packing around its said head.

In carrying out my invention, I locate a 7 suitable body ofpacking A, in the closed outer end of the removable cap B, which covers and protects the spout C, of the oil-can D. The packing may consist of any suitable material, such as rubber, cork, leather, felt, vul- 8o canized fiber, or any other substance which may be found suitable for the purpose. The said packing has an inwardly opening, central, longitudinal flaring passage A, the length of which is such that when the cap is in place, the bottom or inner end-wall act the passage, will clear the end of the spout C, the exterior surface of which is continuously engaged, near its end, by means of the walls of the passage, which are considerably contracted at that point for the purpose, so that the end of. the spout is packed or sealed, not at the point of its opening, but along its exterior surface or sides, laterally. It will be understood that the walls of the passage A 5 are contracted so that, at the point where the spout engages with them, the passage will normally be smaller in diameter than the diameter of the spout. I thus secure a much larger area of contact between the packing mo and the spout than under the old method of jamming or seating the very end of the spout in the packing, and I also avoid the cutting of the packing by the end of the spout, causing the packing to be worn away, and eventually resulting in the leakage of the oil, and also causing the spout to ,be choked and clogged by the entrance into it of bits of the packing, thus cut 0E by the spout. As herein shown also, I employ a clearance pin D, which has a long tapering shank, adapted to enter the spout, and ahead D, which is larger in diameter than the normal diameter of the inner end of the passage A, so that when the pin is forced into the said passage, and its head seated upon the bottom thereof, the rubber will close about it, and hold it in place. When this pin is used, its shank will enter the spout, and not only serve to prevent the passage of oil through it, but also to keep it clear.

I may secure the packing in place in a variety of ways, but preferably I shall do it by forming an inwardly projecting circumferential head A near the outer end of the cap, and in line with the engagement of the packing with the exterior face of the spout, the pack- 1ng being displaced by the bead in such a manner as to.cause it to press inward and contract the passage A at points opposite the bead.

make such changes and alterations as fairly fall Within the spirit and scope of my invention. I am aware, however, that it is old to furnish the cap of an oil can with a packing containing an opening adapted to receive the spout of the can and seal the same by engage ment with the exterior face, as distinguished from the end thereof.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the spout and cap of an oil-can, of a packing located within the outer end of the cap, and having aninwardly opening, central, longitudinal passage, shaped to continuously engage with the exterior surface of the spout near the outer end thereof, and forced inward for such engagement, and held in place within the cap, by a circumferential, inwardly extending bead formed therein, substantially as described.

2. The combination with the cap and spout of an oil-can, of a packing located within the closed outer end of the cap,and having an in-- wardly opening, central, longitudinal passage for the reception of the outer end of the spout, the exterior surface of which it continuously engages, and a clearing-pin adapted to enter the outer end of the spout, and constructed with a head located within the extreme inner end of the said passage, and held in place by the closing of the rubber around the said head, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
