OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 518,539, dated April 17, 1894. Application filed February 15 1894. Serial No. 500,316. (No model.)

To ctZZ whom it may concern.-

0 E. WILLIAMSON, a citlzen of the United States, residing temporar ly at Chicago, Illinois, have invented certain new and useful Improvements inOil- 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.

Much diffioulty is experienced in filling the ordinary spring-bottom oil cans, as they are now usually constructed, because of the comparatively small size of the orifice through which the filling must take place, and it freuently happens that the amount ofoil Wasted 1n such filling is very considerable. Ordinary funnels have been employed to facilitate the filling of these cans,but they become lost or misplaced, and prove in the main unsatisfactory. It has also been proposed to employ a specially constructed funnel which when not 1n use is intended to be slipped over the nozzle and the upper part of the can, but not to be secured thereto. But this is also unsatisfactory for the reason that the funnel often becomes loosened from its seat and finally lost, especially when the can is being carried on some moving piece of machinery, such as a harvesting machine; and further, it cannot be insured that the workman, after uslng the funnel, will place it upon the can so that it will be at hand when it is next desired.

My invention has for its object to combine with an oil-cau of the character referred to, a filling funnel, by such means,orin such manner that the funnel is necessarily always at hand when itis desired; and it has as afurther object to strengthen the can at its weakest points, and to otherwise improve it.

With these objects in View my invention consists of the combinations and arrange ments of the parts of an oil can and a filling funnel to be presently pointed out.

In the drawings wherein my invention is illustrated as being applied to a spring bottom oil can of ordinary shape, Figure l is an elevation of a can provided with my invention and ready for use. Fig. 2 is an elevation showing the arrangement of the parts when the can is to be filled. Fig. 3 is a vertical section of the parts, when assembled as illustrated in Fig. 1. Fig. 4is an elevation of the oiler nozzle, detached.

In said drawings A represents the body of the can which may be of any usual or approved construction.

The neck, B, of the can is externally screwthreaded, while its inner surface ororifice b is finished smooth, as illustrated in Fig. 3.

O designates the tapering nozzle through which the oil is delivered. It is provided near its lower or large end with an externally arranged ann ular flange 0, below which flange there is a smooth portion, 0, of the nozzle which is adapted to fit closely into the apertime, b, in the neck of the can, this fit being as tight as can practically be made, while allowing the nozzle to be easily slipped into or removed from its seat.

D is the filling funnel, consisting of a body part 02 adapted to fit the outside of the upper part of the can body and a neck orspout d which is adapted to fit over, and quite closely upon, the nozzle 0. The funnel is provided with an internal screw-thread e which may be made to engage with the threaded neck of the can, and with an internal shoulder 6, against. which the flange 0 upon the spout bears when the funnel is slipped over the spout.

F represents a packing ring which may be used between the flange c and the end of the neck of the can.

In Fig. 2 the can is shown ready to be filled. The nozzle has been removed and the neck of the funnel is introduced into the orifice of the can, which may now be easily filled, as will be understood. Having been filled, the funnel is removed, and the nozzle put in place by inserting its cylindrical portion into the neck of thecan. It will be observed that the nozzle is not securely held in place by this operation, but that the co-operation of the funnel is necessary in order tosecure it inposition for use. This is efiected by slipping the funnel down over the nozzle and screwing it upon the neck of the can, which results not only in attaching the funnel to the can where it is held securely and is ready at hand when desired for use, but also in securing the nozzle in place, and in packing the orifice in the neck B. It will thus be ICO seen that it is practically impossible for the,

moved, for the reason that the can is practi cally useless without the funnel. p

In the cheaper grades of oil-cans of the characterillnstrated theyfail,sooner or later,

*it largel almost invariably through breakage in one of two places, namely just below the screw threaded neckof the can,or at the lower end of the nozzle. My invention reduces loss from such breakage toa great extent,because thefunnel when in place upon the can operates to brace and strengthen it in both of these weak places. I

It will'be observed that the joint between the can body and the nozzle is particularly adapted to prevent leakage of the oil, by reason of the sliding joint formed by the surfacesb and c, the packing F, and the screw joint 6. with, and the fiangec on the nozzle, and the end of "the neck B be made to fit together closely when the funnel is screwed down.

slightly increases the cost of an oil-can, while rabil'ity, as I have pointed out.

It will be seen that the funnehwhen constructed as described to screw directly to the body of the can, is in effect a clamping nut by means of which the detachable nozzle is held in place ontheoan.
