'Specification Aof Letters Patent. Patented Sept, .12 1911,

Applicationled December 19, 1910. Serial No. 598,006.

To all 'whom 'it' may concern: v

Be it known that I, AUGUST IVAR JOHN- soN, a citizen'of the United States of -Amer' ica,.and va resident of Concord, county oi Merrimack, and State o f New Hampshire, have invented certain provements in Oil-Cans', of which the following is a full and clear specification, reference being had to the ing, in which Figure l is a vertical sectional view of an oil can embodying one form of my invention, showing the parts in aclosed position; Fig. 2 a detail View of the invention applied to a curved-spout can; Fig. 3 a detail View showing a modified form of the regulator, rod; Fig. 4 a detail side elevation of the inlet valve and regulator rod; Figs. 5, 6vand 7 detail vertical sectional viewsof another form of the air inlet valve showing the same in various positions; Fig. 8 a .transverse section throughfthe'stem of the air inlet valve, looking downwardly; and Figs. 9 and 10 are detail side elevations, partlyin sec-- tion, showing a device for holding the-'air valve adjustably open.

My invention relates to that class of handoilers in which means are -provided for regulating the iiow of oil from the can.

. One ofthe objects of my invention is to vprovide an oil-can with a .simple and vellicient attachment for regulating the flow of oil from the. can and for preventing waste of oil and clogging of the oil-outlet; and a further object of my invention is to so con-A structa canof this type that it may (if desired) be used as an ordinary oil can in which -oil'is ejected by pressure upon the bottom of the can. v

A further object is to provide agamst leaka e of oil at the air inlet valve.

Re erring to the drawing by reference letters, adesignates the oil can, -b the spout attached thereto, c a drip cup, and al a strainer fastened in. place over the opening in the spout; these parts may be constructed in any usual or improved manner. Y

The bottom of the can isbulged vinwardly to form a central cavity e, and in the center of' this cavity is formed a hole up through Y which projects a cylindrical valve casing f whose lower end is permanently attached to the bottom by a flange f. The lower end` of this valve casing is open but its upper end is closed except for a central passage throughwhich the stem ,g of the air valve h vcured to it a thumb disk z', new and useful Imaccompanying drawuworks, said valve L being adapted 'to seat against a seatformed on top of the valve casing. The stem gj projects downwardly out of the valve casing and has rigidly sethe position of this disk being slightly above the bottom of Athe can so as to permit the can to stand fiat on .its bottom. Attached to the stem gabove the plate z' is-a cylindrical head j which is in reflect an enlargement of the valve stem` and is adaptedto nicely tit the valve casing, though this fit need not be an air tight one. The valve stem is provided with an air duct .7c yrunning from a point just below the valve disk L to a point near the enlargement j,

and against the under side'oif the top walll groovem'is formed a lateral oil-set o and at this lower end and projecting in the opposite direction is formed another oH-s'et or cut-away portion p.

Resting upon. the valve disk g and pressed normally thereagainst by a spring g 'is the lowerl end of a 'regulator rod 1 which eX- tends up into the spout-and normally closes its exit, this rod being made, as shown in Figs. 1 and 4, of two sections s'land s jointed pivotally together at a point in the spout by a link t pivoted mid-way length to the spout walls.

' It will be observed that when the air valve is forced away from its seat by pressure of the thumb on the plate z', the spout section s of the regulator rod will be drawn inwardly sulciently to open the exit and permit the oil to iiow out, suiiicient air to takethe place of the discharged oil entering through groove m, port c and past the valve seat. Should it be desired to use this device as an ordinary squirt can, the inlet air valve is forced open as far as it will o, whereupon the inner end of the head will press against the packingl and form an oil tight joint, and then the valve stem 1s rotated to bring the pin n. against the inclined face ofthe shoulder p, which locks the valve in open position and holds the head j tightly against the packing Z,- in this position the stopper section s ofthe regulator rod will be withdrawn into the spout and the flexibleA bottom of the can may be operated in the usual way by pressure to expel the oil.

To lock both valves closed, in order to prevent accidental discharge of oil from the spout, the lair valve may be rotated to bring the, pi'n n into the off-set 0,-thereby locking the valve against movement in either direction. This device may be readily used in a can with `a goose-neck spout by making the stopper or valve section s flexible a portion of its length, as shown at s3 in Fig. 2.

As shown in Fig.. 3 the regulator may be made of a singlev unjointed rod provided with an lenlargement or stopper s2 to close the end of the spout, this stopper being preferably tapered toward its point to assist in directing the oil to the place it is desired to drop it; in this form of the device it will be observed the regulator rod is pushed outwardly its entire length when the airv valve is opened, instead of having its outer section drawn inwardly as in Fig. 1. y

In Figsr, 6 and 7, I show the cylindrical valve chamber as being divided by a horizontal partition u through which works in an airtight manner the stem g of the air valve, said stem being provided with an air port v in addition to the air port 7c heretofore described. This partition forms a trap chamber fw between it and the valve seat to catch any oil that might leak past the air valve h, this trap chamber being provided with an annular upstanding flange surrounding the valve stem. It

' will be observed that\ should an-y oil leak down into this trap, it-will be forced' back into the can by thel in-rushing air when the valve is opened, the oil passing in through the port la with the air that passes therethrough.l The port w permits air to pass through the partition u when the valve is open.

It will be observed from Fig. 1 that the end of the spout is sharply orv abruptly reduced in diameter toward its extremity, which extreme end of the spout fits the stopper section s closely. This reduced portion forms a beveled shoulder b', which serves to direct-the stopper section into the orifice-@during theclosing action. The quickjreduction in the diameter of the spout close to. the exit end thereof insures. a quick opening with a short travel of the stopper section and an ample supply of oil.

It vwill be observed that my improvements 55' may be employed with that type of engineers oil can in which the spout projects laterallyfrom one of the side walls of the can.- It v-will be observed also that I may knurl or roughen the spout or the oilfcup at b3 as shown in Fig. 3, to\enable the spout to be grasped in screw' "g and unscrewing it. 'It will be observed rtherthat if desired Imay provide means for holding the air valve partly open, one such device I illustrate in Figs. 9 and 10, in which views the device is shown as consisting of a bail a2 pivotally depending from the flange f' and adapted to swing under the thumb plate z', this bail being swung at a point to the left of the center of the air valve structure and being provided with an upper extending sharpened edge a3 adapted to engage any one of a series of serrations formed on the under face of the thumb disk i. observed that when the valve is forced inwardly from its seat this bail a2 may be swung under the dislc into engagement with one of the serrations therein, and the farther to the right this bail is swung the greater will be the distance of the air valve from its seat and consequently the greater will be the feed. This device will enable the can to be hung or supported above the bearing or other part to be lubricated and the valve so adjusted that the oil will be fed drop-by-drop without manual manipulation.

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

1. An oil can comprising an oil receptacle and a spout, a spout-closing valve seated in the end of the spout, a valve for admitting air 'to the oil-receptacle, means for opening both of said valves simultaneously, means for normally closing both of said valves, and means for locking the valves in closed position.
