IMPROVEMENT IN LUBRICATOR.

T0 A LL WHOM I'I MAY'CONCERN:

I Be it known that I, RICHARD II. TRADENICK, of the city of Pittsburg, county of Allegheny, and State of Pennsylvania, have invented an Improved Oil-Cup; and I do hereby declare that the following is o. full, clear, and exact description of the saine, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in `whch t Figure 1 is an outside view of my oil-cup, placed on the strap which holds the brasscs which surround the crank-pin in position; and

Figure 2 is a section of the saule through the section-line A' B oftig. 1.

My invention consists in so constructing my cup that the oilis fed on the crank-pin only while the engine is in motion, and in so arranging the several parts that the oil is cleared of'all sand or grit which it may contain, and the pure oil only allowed to reach the eranklpin. i Y

'lo en able others skilled in the art to make and use' my invention, I will proceed to describe its construction and,operation.

' A A are the brass bearings which enclose the crank-'ping B,strap which .passes around the brasses, and holds them in place and to the end of the connectingLrod; C, oil-cup. On the bottom of the cup there is a nipple, I), on which a screw is cut, which screws into the strap B,'as shown in fig. 2. The column`.E rises in the centre ofthe cup, nearly two-thirds thc-height of thesides ofthe same, the top being turned out, forming a cupfin whic-h the round ball, F, rests. This column is pierced by the oil-passage G.` This oil-passage is larger at the lower than at the upper end. It may be either conical, as shown, or may be drilled part'of the way with a large drill and the hole finished with a smaller one, leaving a. shoulder, as indicated at 1', fig. 2. V The cup is provided with the top, K, which screws on, the construction of which is'shown in thesection, fig. 2. -'.Ibe setscrew L passes through ,the centre of the cover, the end being turned out, forming a. cup corresponding to that on the column E. This setscrew is turned by its milled head, M, and is firmly secured in any position by the. jam-nut N.

Operation.

The oil is poured into the cup until it reaches nearly to the top of the column E. The ball F is then placed?Y in the cup on the top of the column. The cover is screwed ion' tight, and the set-screw turned down until it almost touches the ball F, leaving only a slight amount of play for the ball between the cups, 'formed by the ends of the column and set-screw, which partially surround it and keep it in place. The play of the ball is increased or diminished, as the amount of oil required to keep the crank-pin properly lubricated is greater or less. When the engine is running, thc oil in the cup is keptin constant agitation, and the ball F is always covered. This ball is constantly pla-ying up and down, and also has a rotary motion. In this rotary motion all thelsand or grit which may be in the oil, and which falls on the ball, is scrapedo on the .edge of the cup on the top of the column, and the pure oil only allowed to pass into the eil-passage G, down which it runs and falls on the crank-pin, keeping it well oiled. The ilow of oil stops when the engine is not in motion, so that no oil is ever lost.

The turning of the crank-pin in the brasscs forms a partial vacuum, which assistsA the oil in its descent. The manner in which the oil-channel is constructed also increases the eicicnc'y of the cup, by breaking the vacuum, from time to time, and allowing the air to reach the inside of the cup, when suiiicient oil has been drawn oil to form a partial vacuum in the same.

Ulaz'm.

What I claim as my invention, and desire to secure by Letters Patent of' the United States, is- The oil-cup C, having the column E, oil-passage G, ball F, top K, and set-screw L, `when 'constructed and operating substantially as and for the purpose set forth. v
