' IMPROVEMENT IN OIL-CUP.

To ALL wHoM '1T MAY ooNcERN.

Be it known that I, EDWIN HURD, of Virginia City, county of Storey, State of Nevada, have invented an Improved Lubricating-Cup.; and I do hereby declare the following description andaccompanying drawings are suicient to enable an'y person skilled inthe art or science to which it most nearly appertainsqto rmake and use my s'aid'invention or improvements withoutfurther invention or experiment. l f

e vThe object of my invention is to provide an improved lubricating-cup, to' be used especially on steamcylinders, or in any place where the lubricant is introduced against pressure; and .it consists of a partiallyrotating cylinder betweenA the receiving-cup and the point at which the oil is used. The cylinder has an opening at the top, corresponding with one from the receiving-cup, when in one position, and when the cylinder is rotated to another position, ahole at thebottom allows the oil to flow to its destination, the upper'opening being meanwhileA closed.

To more fully explain my invention, reference is had to the accompanying drawings, forming a part of this specification, of which- 'I Figurel is a' side sectional elevation.

Figure 2 is a section taken through() D. Figure 3 is a section through A B. Y" t Similar letters of reference indicate corresponding. parts in each-of the figures.

A is a'close cylinder, whichrotates in aframe,'E, turning and working steam-tight on the facesF F. Thecup G, which iirst receives the oil, has a stem, Gr', projecting downwards, the lower end of which is bevelled, so as-to fit theltop of the cylinder at F, and is kept in contact by the nut H pressing on the collar I. i

The lower bevelled. end ofthe cylinder is fitted to the bottom of vthe frame E,"as shown at F, also steamtight. A'handle, J, serves to turn the cylinder a, as far as the frameE allows, in'either direction. An opening, K, passesfrom the cup G down through'the stem G", and, when the cylinder is inthe position shown at fig. 1, this opening connects with the opening L in the top of it, so that the oil or tallow will ilow readilyV into the cylinder, a vent, M, facilitatingthe ow. v In this position the lower opening, N,.of the cylinder does not connect with the opening O, and there is no pressure in the cylinder. After. the cup 'G is em-pty, the cylindera isl turned until the openings N and O connect, when: the oil passes down to its destination, the openings 'K and L being in the mean timeclo'sed. A set-screw, 2P, passes through the side.l of. the frame E; and enters a' slot in the stem, G', thus keeping the stem in a line as thenutH is turned down.

vIn this manner I am enabled to construct a cheap, simple, andperfectly steam-tight lubricating-cup,'which t will also keep itself tight as it wears, and yit cannot-be operated wrong by the most ignorant.

y Having thus described my invention, I do not claim a hollow cylinder pivoted by means of a .centralspindle, with air and oil-passages through the pivotal connections,- as shown inl the patent of M. .Vergnes,'September 25, 1866, and in others; but

What I do claim, and desire to secure by-Letters Patent, is-

The arrangementof the frame E, the hollow 'cylinder a pivoted within it, andfhaving passages for the reception of oil, for the escape of air, and forthe delivery of the oil through the pivots 'onfwhich it turns, substantially as described.

In witness whereof, I have hereunto set my hand and seal.

EDWIN HURD. [1.. s]
