OIL-CUP.

Specification of Letters Patent. Patented NOV. 16, 1915.

Application fi1ed October 5, 1914. Se1'ia1 No. 865,100.

To all whom it may concern:

Be it known that I, (lean. BARNES, a citizen of the United States, residing at Chadron, in the county of Dawes and State of Nebraska, have invented certain new and useful Improvements in Oil-Cups, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to certain new and useful improvements in oil cups and has for its object the production of a cup simple and economic of construction and adapted to deliver the oil at a uniform rate and until the entire contents of the cup have been utilized.

With these ends in view my invention consists in the details of construction and arrangement hereinafter more particularly described.

In order that those skilled in the art to which my invention appertains may know how to make and use my improved oil cup and appreciate its advantages I will now describe the same referring by numerals to the accompanying drawing, in which Figure 1 is a central vertical section of an oil cup embodying the features of my invention. Fig. 2 is a section on the line (Ir-a of Fig. 1. Fig. 3 is a transverse section on the line bb of Fig. 1, and Fig. 4 is a bot tom plan view.

Similar reference numerals indicate like parts in the several figures of the drawing.

1 is a cup of metal or other suitable material reduced at its lower extremity and threaded as shown at 2 and adapting it to be secured in place.

3 is an ordinary cap or cover, 4 is the bottom and 5 is the oil space.

Located in the bottom and at one side of the vertical center of the receptacle is a tube 6 terminating at its lower end coincident with the extremity of the threaded portion 2 of the cup and terminating at its upper end about midway of the receptacle as clearly shown.

7 represents two strands of copper wire twisted together in helical form the cross section area of which is such as to contact with the inner circumference of the tube 6 while at the same time permitting of its introduction to or removal from said tube.

The irregular flash-like lines within the oil receptacle are intended to represent a body of suitable absorbent material such as cotton waste, etc, having also capillary properties.

By special reference to Fig. 1 it will be seen that the absorbent material envelops the wire conductor 7 and by reason of its absorbent and capillary properties delivers the oil taken up by it to the helical wire conductor which latter as will be noted is of siphon form, and it will be also noted that the helical channel formed between the coils of the wires and the wall of the tube 6 constitutes a conduit for the oil delivered to the conductor and that the siphon form of the said conductor facilitates the flow of oil to the point of delivery at the lower extremity of the oil cup.

The number of channels formed by the coiled wire and-the inner face of the tube 6 will of course depend upon the number of wires used to form the coil. Where three wires are used, three helical channels are provided, and when four wires are used, four helical channels are provided. The smaller these channels are the greater will be the capillary attraction, and the more channels there are the greater will be the amount of lubricant delivered.

The tube 6 is secured within the bottom of the oil cup by frictional contact to such a degree as to prevent the passage of oil between it and the bottom of the cup, while at the same time permitting of its removal for any purpose when necessary, such for instance as cleaning the cup.

While I have shown the body and cap of the cup of cylindrical form and the cap secured in place by screw threads, it will be understood that neither the design of the cup nor the manner in which it may be secured in place constitute part of my invention and may be varied in these particulars and while I have shown the copper wire conductor as composed of two strands of wire twisted together helically I may employ a conductor composed of a single wire the cross section area when twisted being equal as heretofore stated to the interior area of the tube 6, and while I prefer to employ copper wire any other material having the equivalent properties may be used.

What I claim as new and desire to secure by Letters Patent is 1. In an oil cup, an oil container having a delivering passageway extending through it, and a conductor disposed in said passage- 15 posed in said tube and extending out of the way and comprising a plurality of twisted wires, the conductor havinga diameter approximately equal to the interior diameter of the passageway whereby said wires will approximately contact with the inner face of the passageway to thereby provide a plurality of helical oil channels between said conductor and the inner face of the passageway.

2. In an oil cup of the character described, an oil container screw-threaded at its base to be secured in position and provided With a tube extending through the base and into the container to a point above the bottom thereof, and a conductor disupper end thereof and then bent toward the base of the container, said conductor comprising a plurality of Wires twisted upon each other, the conductor having a diameter conductor and the inner surface of the tube.

In testimony whereof I hereunto aiiiX my signature in the presence of two wltnesses.
