vINEI?ROVEMEI'J IN OIL-CUPS-AND BEARING-S FOR SPIND/LESI.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, EUGENE GoNvEns, of Oswego, New York, have invented new and useful Improvements in the Construction of Shafts or Spindles and Steps therefor; and I do hereby declarethat the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters of reference thereon, "making part of this specification.

. In the drawiugs- Figure l is a vertical section of the shaft and step. iugm-e 2 is a side view. Figure 3 is an inside view of the cap.

Figure 4 shows the collar, with the lugs thereon,

byj which the cap is held in position.

The object of my invention is to provide means for lubricating the gudgeon of the shaft, so as, at the same time, to exclude dust and organic mattei' from the oil-box, and prevent heating and wear, while economizing the lubricating material.

It consists of the parts and combinations hereinafter described.

Iusteadot' making the shaft with a pointed end, as customary, I drill a hole in Vthe end, and in the oilbox or step make'apivot on which the shaft may revolve. The oil-box being larger than the end of the shaft, there is no friction.

Near the` end of the shaft, at a point corresponding with the top ofthe oil-box, I place a collar to support the protecting cap. This collar has projections or lugs to lit corresponding notches in the inside of the cap, so as to hold the cap inplace, and cause it to revolve with the shaft. rIhe cap is tted closely to the collar, but freely upon the oil-box, so as to prevent friction. It is also movable upon the shaft, facilitating the examination and cleaning or'oiling of the pivot ends.

The hole in the end 0i' the shaft and pivot upon which it revolves are shown at a, fig.. 1.

The collar on the shaft is shown at b, lig. 2, and also detached iu fig. 4.

The lugs or projections are indicated at e, figs. 2 and 4.

The cap, moved up on' the shaft, is shown at c, fig. 2, and an inside view is presented in tig. 3. A sectional view is also presented. at o, iig. 1.

By means of this method of constructing shafts lor spindles, .dust and foreign matter are excluded from the pivot end. The cap, revolving with the shaft, acts as a fau to throw off dirt from the outside. As now constructed, oil-boxes are left openl and exposed, forming ready receptacles for all the dust and dirt created around them. 'Ihe entrance of this dirt is by my method entirely prevented, and the consequent heat-- ing and wear of the pivot end prevented.

What I claim as my invention, and desire to secure by Lettersl Patent, is

' l. The combination of the movable cap and collar b o, iig. 2, constructed substantially as described and for the purposes set forth.

2. The shaft, with hole in the end, and corresponding pivot fixed in the oil-box or step a, g. 1, as described, and for the purposes set forth.

3. The combination of sliding cap c, the spindle f, having a collar b, with lugs c, and the oil-cup g, the cap revolving with the spindle, and notin'contact with the oil-cup, in the manner and for the purposes substahtiall y as shown and'described.

In testimony that I claim the above, I have here nuto subscribed my name in the presence of' two witnesses.

Witnesses: E. GONVERS.

JOHN B. MoTLnr, EDM. lifBRoWN.
