O l L-CAN SPEGIFIQATION forming part of Letters Patent No. 465,467, dated December 22, 1891. I Application filed August 10, 1891.- Serial No. 402,263- (No model.)

jTo all whom it may concern:

useful Improvements in Oil-Cans, of whichthe following is a specification.

My invention relates to oil-cans; and it consists in an improved can, a d m re ticularly in'meansfor regulating the discharge of oil'and for preventing oil from spilling at the vent.

In the accompanying drawings, in which like reference-signs. refer to similar parts throughout the several views, Figure 1 is a central sectional view of the entire can. Fig. 2- is a similar view of the combined vent and stopper. Fig. 3 is a side elevation of the same; andFig. 4is a side elevation of the can, the spout being broken away.

The objects of my invention are to provide a can having means for controlling the flowof oil from the spent, to provide a vent which will permit the inflow of air without the danger of leakage when the can is temporarily reversed, so as to cause the oil to flow through the spout, and, in general, to provide an oilcanwhich shall be convenient and economical and well adapted to lubricate the various portions of locomotives and other machinery \vhichare more or lcss'inaccessible.

In the accompanying drawi" A inc sates the body of the oil-can, B the handle, and indicates the filling-tube which, as shown, is attached to the conical top portion A of the can. The tube 0 is internally threaded at its upper end and closed bya cap provided with a threaded ring J. The conical top A of the can is surmounted by a spout E, which is .united to it by a screw-joint. The spoutE is provided at its upper end withan internal threaded ring L, and into this ring is screwed a hollow nut M. The lower end of the nut M is beveled or coned to form a scatter a valve N, and into the upper end of the nut is screwed a suitable tip or nozzle F, which may be bent in any desired manner.

The valve N is threaded upon' the longer leg 0' of a U-shaped rod 0. The leg 0 ex- .mally pressed to its seat.

tends centrally down through the spout into 4 the body of the can to the curve. of the .U,'alid". from thence the shorter leg 0 extends upward through the conical top A at a pointadjacent to the handle. 'A spring S, which rests upon a bracket T, attached to the conical portion A, serves to keep the valve nor- The shorter leg 0 passes upward through a stuffing-box PQ and to its end. When the button R is pressed by terminates in a button R, which is attached the thumb or finger, the valve -N is opened and oil permitted to flow through the nozzle F. Upon releasing the button the spring S quickly closes ,the valve. It is important that the legs 0' 0 should be parallel to each other, or nearly so, and that the leg 0 be placed at near to the leg 0' as possibla so as to give greater strength to the bent portion of the valve-rod. It is furthermore necessary to have the button R located conveniently to the handle, so that it can be reached by a thumb or finger of the hand which holds the can. For these reasons I have placed the leg 0 between the handle and the spout, permit-' ting it to pass up through the top of the can. The combined vent and stopper consists of a hollow casing D, substantially cylindrical in form, having a threaded ring J attached thereto for connecting it to thefilling-tube.

In order to make a tight joint, a washer K of leather or similar material may be placed between the flange of ring J and the tube 0. At the center of the lower end of the'casing D is a small vent-hole II, and from a similar hole in the upper end a small tube G extends centrally downward to the lower port-ion of the casing. When the can is in use, air will pass in through the openings G and H to supply the place of the oil'which runs outof'the nozzle. If at the same time the oil should, leak through the hole H instead of spilling, and thus being lost, it will be caught in the'casing D, the tube Gpreventing it from running out of the casing. When the can is again held with the spout up, this oil will run back into it through the hole II. Thus while the vent admits air freely it forms a trap to prevent the oil from leaking.

In order to ascertain at any time the amount of oil in the can, I provide a longitudinal slit in the side of the body A, backed by a piece of glass U, which is held in place by a strip V, which is soldered to the can.

The spout E being larger thanthe valve, it can be readily detached from the can to be cleaned, at the same time leaving the valverod and valve exposed. Thus any accumulations of dirt or any derangement of the spring for operating the valve may be readily remedied. The button R and the cap Q, of the stuffing-box are also made removable, so that they may be readily cleaned or replaced.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The herein-described oil-can, consisting of an oil-receptacle, a spout, a nozzle, a detachable nut between the spout and nozzle, said nut being formed with a valve-seat in its lower end, avalve fittingsaid seat, a U -shaped valve-rod extending through the spout into the body of the can and upward through a stuffing-box in the top thereof, a filling-tdbe at the top of the ean,and a combined stopper and vent fitting said tube and consisting of a cylindrical casing provided with the perforation II,'tube G, and ring J, substantially as described.

2. The combination, with an oil-can, of a vent consisting of a substantially cylindrical casing, the lower end of the casing being closed, excepting a small perforation, and the upper end being provided with a similar perforation, and a tube extending therefrom downwardly nearly to the bottom of the easing, substantially as described.

3. The combination, with an oil-can having a filling-tube threaded at its outer end, of a combined stopper and vent consisting of a cylindrical casing having, an attached ring J, threaded to fit the filling-tube, said casing having its lower end closed, except a small perforation at its upper end provided with a similar perforatiomand a small tube extending from said latter perforation nearly to the bottom of the casing, substantially as (lescribed.

In testimouy whereof I allix my signature in presence of two witnesses.
