UNITED STATES ARTHUR R. BENTON, OF BEVERLY HILLS, CALIFORNIA.

HAND OILER.

Application led January 7, 1926.

'lhis invention involves improvements in squirt cans or hand oilers or that type ot liquid dispensing cans provided with a dis charge spout and a wall portion suoli as a flexible or elastic bottom that can be depressed by the thumb or lingers to cause liquid discharge from the spout; and the objects and nature ot the invention will be readily understood by those skilled in the art in the light of the following explanations of the accompanying drawings that illustrate what I now believe to be the pre iierredmechanical expression or embodiment of my invention from among other forms, constructions and arrangements within the spirit and scope thereof,

An object of the invention is to provide means whereby a hand oiler or liquid dispensing can having a discharge spout, will bei rendered capable of discharging liquid upwardly when the can is held in upright position with the spout upstanding therefrom, Without interfering with the capacity of the can to dispense liquid from the spout when the can is held in inclined position or in a reversed position with the spout de pending from the can.

With the foregoing and other objects in view, my invention consists in certain novel features of construction, or in combinations and arrangements as more fully and particularly set forth and specified hereinafter.

Referring to the accompanying drawings forming a part hereof:-

Fig. 1 shows a hand oiler embodying my invention, in longitudinal section, the handl oiler being shown in vertical position with its discharge spout upstanding.

Fig. 2 is a side elevation showing the hand oiler in reversed position with the spout depending from the can, dotted lines showing the position oi theplunger or eX- tension oil discharge tube.

F ig. 3 is a side elevation showing the hand oiler in tilted position,` dotted lines showing the position of the plunger.

Fig. il shows in detail, the plunger and liiushing separated from each other' and from the oiler.

From among the various other forms ot spouted liquidfdispensing cans or other containers in which my invention can be employedr`r I have selected -for illustration a common, simple i'orm ot oil can, or so called Serial No. 79,764.

denoy to` return to such outwardlyv bulged formatter being pressed inwardly and ref leased. The can' is formed with a. top-filling mouth or opening surrounded by a longf? tudinally screw threaded upstanding neck 3, to receive the longitudinally screw threaded closure or cap 4C, that normally is removably fitted on the neck tightly closing said opening'.

In the example shown,the cap a, carries the rigid discharge nozzle or spout 5, which is fixed to and opens through the cap. In this instance, the spout is straight and Vertical upstanding from the cap when the can is in normal upright position, and is also longitudinally elongated and-tapered from its junction with the cap to its small or contracted outlet or discharge nozzle end, although I do not wish to so limit my invention.

Hand oilers of this general typecan be employed for-discharging oil or other liquid in such situations that permit tilting or reversed positions ot the can during the liquid dispensing operation, to bring` the inner or receiving end of the spout below the oil level in the can so that the liquid can flow from the can through and discharge rom the spout by gravity or under the forcing air pressure in the can caused by depressing the bottom 2. Such hand Oilers of thisV general type cannot, however, lift or discharge or dispense oil or other liquid vertically through the spout when the can is held in upright position with the body of oil below the inner ortinlet end of the spout, and it is the purpose of my invention to render it possible for dispensingI cans of this general type to dispense liquid vertically from the nozzle discharge end of the upstanding spout when the can is held in normal vertical position.

To accomplish this result, I provide the hand oiler with an inner spout extension that provides the sole air and oil inlet to the spout and that locates this oil inlet to the spout always below the oil level in the can or always within the body of oil, what ever the position of the can whether tilted, vertical or reversed.

By this arrangement, a sudden or other increase in pressure within the can as caused by depression of aliexible wall portion of the can, such as flexible or resilient bottom 2, will force the oil in the can to take the only possible path of release provided, namely, upwardly through said extension and the spout and upwardly from the spout discharge nozzle. The air in the can is trapped above the body of oil and finds no outlet as the inlet to the spout is completely immersed in the oil, and the increase in pressure in the can is sufficient to lift oil through the spout and cause upward discharge of a jet of oil from the spout nozzle.

Under various conditions, it is convenient or even necessary to supply lubricant to `machinery or other parts where it is not possible to hold ahand oiler in reverse or tilted positions. For instance, this situation often arises where working in'a pit under an automobile or under an automobileelevated on a truck or track.

In the particular embodiment illustrated, this inner spout extension is in the form of a straigt tube 5', having sliding telescoping relation to the spout, the bore of the tube having no outlet except at its outer end 5,

"within the spout and no inlet except atits inner end 5b, within and covered by the body of liquid within the can. v

This tube is longitudinally arranged within the longitudinal bore or liquid passage of the spout with a freely slidable running fit to prevent air or' liquid leakage through the spout exteriorly ofthe tube. The capacity of the tube to freely slide longitudinally is facilitated by the lubricating quality ofthe film of oil on the exterior surface of the tube which also aids in maintaining the air tight joint between the tube and surrounding interior surfaces within the spout. The length of the tube materially exceeds the distance from the can bottom to the inner end of the spout so that a substantial length of the tube will extend upwardly in the spout when the tube is at its limit of downward movementin the can, and so that the outer end of the tube will preferably terminate short of the nozzle discharge end of the spout when the tube is at its limit of outward movement within the spout.

The tube is freely slidable longitudinally of the spout, by gravity as its center of gravity changes due to shifting positions of the can to and from the upright vertical position, and hence to render the tube quickly responsive to such changes in gravity positions, I preferably weight the tube. For instance, I'show the inner end of the tube that always remains within the can, formed with radially enlarged end head 5c,

thus weighting the tube at its inner end, and providing a stop to engage the cap and limit the outward sliding movement of the tube, and engage the can bottom and limit the inner or downward movement of the tube. The end head 5c, is formed of such a diameter and thickness or depth as to lit within and occupy the lilling opening and neck 3, so that, in inverted position of the can with the tube at its outward limit of movement in the inner wall of head 5 will be substantially flush with or spaced outwardly (downwardly) in filling neck 3, from the top wall of the can to permit of complete discharge or emptying of the oil in the can through tube 5 and its inner end 5", as will be clear by reference to Figs. 2 and 3 of the accompanying drawings.

At its bottom face, this head 5, is formed with cross grooves 5d, opei'iing into the inlet end of the tube bore to provide for free passage of the oil to the bore when the head rests on the can bottom.

lllhen the can embodying my invention is held in upright position, the tube is at its limit of downward movement with its inlet end immersed in the oil, and if the bottom 9. should then be depressed, the pressure thereby resulting within the can will cause upward discharge of the oil from the spout as hereinbefore described. If the can is tilted or reversed, the tube will slide outwardly by gravity to its limit of outward position with the inlet end of the tube covered by the oil, so that oil will discharge by gravity or under pressure from the spout nozzle.

My invention presumes that the internal formation of the bore of the oil can spout, provides `the necessary length of uniform cross sectional dimensions, to cooperate with the sliding extension tube in forming an air tight running lit exteriorly of the tube, as hereinbefore explained. y

To adapt my invention to hand Oilers of the squirt type and the like, now on the market, wherein the spout bores longitudinally contract or taler toward their dis charge nozzle ends a out as shown, I provide a filler or bushing 6, which can be inserted in said spouts through their inner ends with the plungers or extension tubes 5.

Each bushing 6, is in the form of a tube exteriorly tapered longitudinally to lit and wedge within the nozzle and assume a fixed position therein forming an air tight joint between the inner nozzle surface and the outer surface of the bushing. The longitudinal bore 6u, of the bushing corresponds in cross sectional dimensions to the corresponding exterior dimensions of the plunger or extension tube therein to provide the freely slidable running fit desired.

It is evident that various changes, modiications and variations can be resorted to loo Without departing from the spirit and scope of my invention and hence I do not Wish to limit myself to the exact disclosure hereof.
