OIL-CUP.

SPECIFICATION forming part of Letters Patent No. '77 9,959, dated January 10, 1905.

Application filed May 14, 1904. Serial No. 208,006-

To (all whom it may concern:

Be it known that we, JOHN H. MGGINTY and JACOB HUBER, citizens of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Oil-Cups; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in Io the art to which it appertains to make and use the same.

Our invention relates to lubricators or oilcups.

It has for its object to provide a simple and efficient device adapted especially for use on the hubs of loose pulleys.

The invention consists of an oil-cup having a circumferential passage therearound, a reservoir fitting within said cup and provided with a passage for feeding the oil therefrom through said circumferential passage to the outlet, adjustable means to hold the reservoir in place in said cup. means on the outer face of the reservoir to indicate the position of the passage therein, and means for insuring the passage of the liquid from the cup to the shaft.

In the accompanying drawings, illustrating the preferred embodiment of our invention,

Figure l is a side elevation of our preferred form. Fig. 2 is a sectional view on line 0? 0c of Fig. 1. Fig. 3 is a sectional view on line 3/ y of Fig. 2. Fig. 4 is an elevation looking toward the outer end of the reservoir.

Fig. 5 is a top plan view. Fig. 6 is aperspective View of the reservoir detached. Figs. 7 and 8 are side and plan views, respectively, of a modified form; and Fig. 9 is a sectional view of a pulley, showing different positions which the cups may occupy.

Referring more particularly to the drawings, the cup 1 may be made of any suitable metal, is generally cylindrical in form, with one end open and one end closed, and has a bail 2 pivoted at opposite sides near the open end. Said open end has its face preferably beveled, as at 3, to engage a correspondinglybeveled face 4 of the head 5 of the reservoir 6, which is adapted to nicely fit said cup.

Said reservoir is closed on all sides, except for 5 a longitudinal slot 7, extending a short distance about centrally of the longitudinal axis of the cylindric receptacle. The head 5 of the reservoir has a raised pointer or arrow 8, preferably cast integral with said head. to indicate the position of the slot 7 when it is desired to remove the reservoir from the cup. Said head also has a central projection 8, which is screwthreaded and engages a thumb-screw 9, having a projecting flange 10, adapted to engage the under side of the bail 2, which is provided with an open slot 11, fitting above said flange. By turning the thumb-screw so as to bring the flange into forceful contact with the hail the reservoir is held securely in place in 5 contact with the cup, while by reversing the thumb-screw and turning back the bail the reservoir may be withdrawn for refilling. Before withdrawing the reservoir it should be turned with the indicator pointing upward, 7 0 so that if there is any oil left in said reservoir it will not be spilled.

A circumferential passage 12 extends around about midway of the cup and communicates with the outlet. Through this passage the oil may pass from the reservoir, no matter where its opening is located. In our preferred form instead of the direct passage from the circumferential groove to the outlet we form a chamber 13 at the top of the cup 30 communicating with said groove and with external tubes 14:, which pass around said cup and empty into a chamber 15, arranged at the base of the cup just above the outlet. We have found that owing to centrifugal force 5 the oil is thrown outward as the pulley revolves, causing said oil to collect in the chamber 13, from which it is fed through the tubes 14. to the chamber 15 and thence to the shaft. To facilitate the feeding of the oil through 9 the outlet-passage to-the shaft, we provide a roller 16, which is placed in the chamber 15 and has attached to it a wire 17, extending down upon the shaft. The roller has an enlargement 18 at one end and is pointed at the other end and is adapted to center in a conical socket in a preferably detachable nut 19. The oil in the chamber 15 is agitated by the roller and is fed along the wire to the shaft. A suitable vent-valve 20 may be used in connection with the chamber 15.

We are aware that detail changes may be made in ourdevice without departing from the spirit or sacrificing the advantages of our invention. e therefore reserve the right to make such changes as fairly fall within the scope of our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described, a cylindric cup having an inner circumferential groove communicating with an outlet-passage, a cylindric reservoir adapted to fit within said cup and having an outlet in alinement with the groove in said cup, and means for securing said reservoir to said cup.

' 2. In a device of the character described, a cylindric cup having an inner circumferential groove communicating with an outlet-passage, a cylindric reservoir adapted to fit within said cup and having an outlet in alinement with the groove in said cup, said reservoir having a pointer on its exterior face to indicate the position of its outlet, and means for securing said reservoir to said cup.

3. In a device of the character described, a cylindric cup having an inner circumferential groove communicating with an outlet-passage, a cylindric reservoir adapted to fit within said cup and having an outlet in alinement with the groove in said cup, and a bail on said cup adapted to engage said reservoir to hold it in connection with said cup.

4. In adevice of the character described, a cylindric cup having an inner circumferential groove communicating with an outlet-passage, a cylindric reservoir adapted to fit within said cup and having an outlet in alinement with the groove in said cup, and a bail on said cup adapted to engage a flange on a thumb-screw carried by the reservoir whereby said reservoir is held in connection with said cup.

5. In a device of the character described, a cylindric cup having a circumferential groove, said cup also having a chamber communicating with said groove and arranged above said cup and a second chamber arranged below the cup and provided with an outlet, means of communication external of said cup, between said chambers, a cylindric reservoir having an outlet in alinement with said groove and adapted to fit within said cup, and means for securing said reservoir to said cup.

6. In a device of the character described, a cylindric cup having a circumferential groove, said cup also having a chamber communicating with said groove and arranged above said cup and a second chamber arranged below the cup and provided with an outlet, external tubes extending around said cup and communicating with said chambers, a cylindric reservoir having an outlet in alinement with said groove and adapted to fit within said cup, and means for securing said reservoir to said cup.

7. In a device of the character described, a cylindric cup having a circumferential groove, said cup also having a chamber communicating with said groove and arranged above said cup and a second chamber arranged below the cup and provided with an outlet, external tubes extending around said cup and communicating with said chambers, acylindric reservoir having an outlet in alinement with said groove and adapted to fit within said cup, and means for securing said reservoir to said cup, and a roller arranged in said lower chamber having one end centered in a conical cavity on said roller carrying a wire projecting into the outlet for feeding the oil to a shaft.

In testimony whereof we affix our signatures in presence of two witnesses.

JOHN H. MOGINTY. JACOB HUBER.
