l-iGlaim.

This invention arelates .generally eto. sellers pertains particularly to improvements in-- hand oilers or oiling "cans;

The present invention :hastfor' its .principal object to "provide anximproved.oiling can which is designed :in such a manner :as to :makepossible the. easy ejection offoilywhen the-.caniis nearly empty, with the can in aspartly or fully invertedother words,,to.holdthecanentirely upside down.

If it is necessary toholdthe can partly inverted the small quantity of oil inthe can will settle in the-lowestflpart below theinlet end of the-spout so'that; the. oil cannot. be ejected.

The present invention isdesigned to facilitate the ejection of all of the oil from the can when only -a;small quantity ofioilaremains, even though the can, maybe .inverted only part way, by-the provision of an oil trapping means at the angle formed between the bottom and the side wall of the can so that such oil as gathers in the low part of the can or receptacle when the can is only partly inverted, can be forced to and out through the can spout.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of the specification, with the understanding, however, that slight changes or modifications may be made in the structure without departing from the spirit of the invention so long as such changes or modifications are within the scope of the appended claim.

In the drawing:

Figure 1 is a view partly in side elevation and partly in vertical section of an oil can constructed in accordance with one embodiment of the present invention.

Figure 2 is a sectional view partially through the lower part of the receptacle, taken on the line 2-2 of Figure 1.

Figure 3 is a view partly in side elevation and partly in section of another embodiment of the invention.

Figure 4 is a partial sectional view taken substantially on the line 44 of Figure 3.

Referring now particularly to the drawing, especially Figures 1 and 2 thereof, the numeral 2 I0 generally designates a "receptacle of the :usual form .or design, having. the outwardlyfbowed bottom. wall I I which is. resilient and 'functions as apumping diaphragmtoforce .the oilfrom within the receptacle. .Suchhand oilers have the-side wall I2 tapered to thetcircular neck Ildefiningthe outlet opening for thereceptacle -and suchneck is provided with suitable screw threadsfilto: facilitate the attachment Itheretoofthe cap Ill.

In the construction shown in Figure "-1, broken threads I-5 are illustrated, such typeofthreadbeing particularly desirable when it is required" that the cap M. be connected with the heck-"I3 witha minimumaof rotation. However, 'itis :to, be understood-that the invention is not limited to the use of this .particulartype of thread as any otherzsuitableconnecting means between thecap. and" the neck. may be employed.

Attached at one end to and" openingthroug'h the central part of' 'the cap M; is the spout Ii which is straight throughout. the major portion-of its length and disposed upon the-axial centerofi' the receptacle I I]; Atxits: outer: end the spouti'has the laterally curved/discharge tip ILL the particular purpose off which willabehereinaftermore fully described.

At its inner end there is connected with the spout, one end of a tube I8 which is bent to provide the obliquely extending portion I9 which terminates in the short straight inlet tip 20. The length of the tube I8 is such that when the cap I4 is threaded tightly onto the neck I3, the inlet tip 20 will lie in close proximity to the bottom of the can and to the side wall thereof or, in other words, the inlet tip will lie in the corner or angle formed between the bottom and the side wall.

Means is provided at the inlet tip of the tube I8 to form a trap which is designated 2| and in the embodiment of Figure 1 this trap is provided by securing to the inner side of the wall I2 a plate or web 22 which extends downwardly and inwardly toward the bottom I I, leaving just sufficient space between its free inner edge 23, and the bottom of the can, for the tip 20 to extend thereunder. Thus the inlet end of the tip 20 is entirely within the oil trap 2|.

The terminal inlet tip 20 of the tube I8 extends in the same direction as the outlet tip I1 of the nozzle and the pitch of the threads I 5 is such that when the cap I4 is screwed down tightly upon the neck I3 the tip 20 will be brought into position beneath the web 22 or in the oil trap. Thus when the can is tipped or turned onto its side for the purpose of ejecting oil from the dis-Q.

charge tip l'l, if the oil is low in the can it will collect or be caught in the trap 2| where the inlet end of the tube l8 lies and thus when the bottom is forced inwardly to create the necessary internal pressure for ejecting the oil through the nozzle, the trapped oil will be discharged into the tube I8 and forced through the nozzle.

Another embodiment of the invention is illustrated in Figures 3 and 4. In this construction the receptacle is generally designated l0 and the cap and nozzle are the same as in the form shown in Figure 1 and need not, therefore, be specifically described.

In this embodiment the tube l8, which carries the oil from the bottom part of the receptacle to the discharge spout, has the obliquely directed portion I 9' which is in the same relation with the tip of the spout as the portion IQ of the structure shown in Figure 1, but the oil trap forms an integral part of the inlet end of the tube, such trap here being generally designated 24. This trap 24 is in the form of an inverted receptacle 25, which forms an integral part of the end of the oblique portion IQ of the tube and is shown as being of circular design although any other form or design may be employed.

The open side of the receptacle 25 is directed downwardly toward the bottom of the receptacle I 0' and is in close proximity thereto as shown in Figure 3 in addition to being disposed closely in the angle between the can or receptacle bottom and side walls.

It will be seen from the foregoing that the action of the embodiment of Figures 3 and 4 will be the same as that of the embodiment of Figures 1 and 2 which is that when the receptacle is partly inverted and is only partly filled with oil or the oil level has dropped to a very low point where the receptacle is practically empty, such oil will collect in the corner between the side and bottom walls and when the can is in the proper position for discharging from the nozzle tip, the collected oil will be received in the trap 24 from which it can be readily ejected when the bottom wall of the can is pressed inwardly.

From the foregoing it will be readily apparent that an oil can constructed in accordance with the present invention provides means whereby practically the last drop of oil may be ejected therefrom even though it may not be possible to completely or entirely invert the can as is necessary in those types of oil cans where complete inversion is required to get the last bit of oil into the cap for discharge into the nozzle.

I claim:

A liquid dispenser of the character stated, comprising a receptacle having a bottom and a side wall which tapers to a central top opening, a spout connected with said opening, a tube connected at one end with the inner end of the spout and extending downwardly and laterally in the receptacle and terminating in a short straight inlet tip portion having its end relatively close to the side wall of the receptacle and in the angle between said side wall and the receptacle bottom, and means forming a liquid: trap at the inner end of the tube, with which the said end of the inlet tip portion is in communication, the said trap com-' prising a web extending transversely of and attached to the receptacle wall and having a free edge in spaced relation with the bottom wall and extending across the top of and spaced from said tip portion, the. said free edge of the webbeing the same distance throughout its length from the receptacle bottom Wall whereby the tip portion may be shifted in either of two directions horizontally from beneath the web.
