IMPROVEMENT IN AUTOMATIC OIL-CUPS.

Specification forming part of Letters Patent No. 185,505, dated December 19, 1876; application filed November 16, 1876.

To all whom it may concern:

Be it known that I, S. P. DONKEL, of Hastings, in the county of Barry and in the State of Michigan, have invented certain new and useful Improvements in Automatic Oil-Gups; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of an automatic lubricator for wagon and carriage axle-trees, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which Figure 1 is a longitudinal section of my lubricator; and Fig. 2 is a side view of a detached part thereof.

A represents the oil-cup made in the form of a tapering cylinder, and provided with exterior' screw-threads to be screwed through the hub of a wagon or carriage wheel, the lower end of said cup fitting in a countersink in the iron pipe or box of the hub. In this end of the box is an oil-passage, a, through which the oil passes to the spindle. Bis a cylinder closed at the upper end, open at the lower end, and screwed into the bottom of the oil-cup A. Near the lower end of the cylinder are two slots, b b, running longitudinally, as shown. Insideof this cylinder is a plunger, 0, which, when the oil-cup is in the position shown in Fig. 1, closes not only the slots b b, but also the passage a in the bottom of the oil-cup. When the wheel revolves and the oil-cup is bottom side up, the plunger 0 falls by its own weight, opening the slots b and allowing the oil to flow in and fill the cylinder B, or as much as is needed to keep a constant supply. When the oil-cup again comes rightside up the plunger 0 drops down, forcing the oil in the cylinder B out through the passage or to the axle-tree, thus giving a small supply of oil at each revolution of the Wheel.

The amount of oil thus fed to the axletree is regulated by means of a sleeve, D, surrounding the cylinderB, and which sleeve can be adjusted up and down, as required, to lengthen or shorten the slots b. The sleeve D is provided with a longitudinal slot, h, one edge of the metal in said slot being formed with a series of notches, m w, to fit over a pin, 1, made fast in the cylinder B, whereby the sleeve may be adjusted and held as required. The upper end of the cylinder B is formed With a groove at 1, so that by means of a screw-driver the cylinder can easily be taken out, when required, for cleaning and other purposes.

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

1. The combination of the oil-cup A with passage a, the cylinder B, with slots 1) b, and the plunger 0, all constructed substantially as and for the purposes herein set forth.

2. The sleeve 1), provided with the slot h and notches a, in combination with the cylinder B, having slots 11 b, and pin 2', substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 2d day of November, 1876.

SIMON PETER DONKEL.
