LUBRICATQR.

Specification of Letters Patent.

Application filed June 17,1905. Serial No. 265.731.

eflicient lubricator designed more especially for use on upright piston-rods and valvestems and adapted to be expeditiously applied to and removed from the same without the employment of skilled labor or tools.

The invention will be fully understood from the following description and claims when taken in connection with the accompanying drawings, forming part of this specification, in which Figure 1 is an elevation illustrating the lubricator constituting the present and preferred embodiment of my invention in its proper position on a piston-rod. Fig. 2 is a horizontal section taken in the plane indicated by the line 2 2 of Fig. 1 looking downwardly. Fig. 3 is a horizontal section taken in the plane indicated by the line 3 3 of Fig. 1; and Fig. 4 is a detail enlarged transverse section illustrating the relative arrangement of the band, the wick, the swab, and one of the oil-cups of the lubricator, together with the means whereby lubricant is supplied to the swab and the wick from the cup.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which A is the band of the lubricator, which is preferably a strip of brass or other sheet metal and is therefore possessed of more or less resiliency, whereby its ends have a tend ency to spring apart, and B is the connection for the ends of the band. This connection is preferably a loop pivoted to one end of the band and arranged to be swung into and out of engagement with a lip or keeper (.4 on the other end.

C C are oil-cups, of which three are prefering transversely through the lower portion of the band, as clearly shown in Fig. i. The hollow arms w serve to [ixedly connect the oil-cups U to the band A, and by reason of the slits 1? it will be observed that the said hollow arms are in communication with the cups throughout the height thereof, with the result that a full supply of oil to the ports or d nets (2 at all times is assured.

l) is a wick substantially corresponding in length to the band A and arranged at the inner side thereof, so as to receive lubricant from the ducts or ports 1 and E is a swab, preferably of cord, wrapped around the band A and the wick l) and also around the hollow arms and having for its functions to apply lubricant to the pistonro .l or other piece of machinery bearing the lubricator and retain the excess supply of lubricant, so as to prevent waste thereof.

The lubricator is applied as shown in Figs. 1, 2. and 3 of the drawings-that is to say, it is placed about the pistonrod, valve-stem, or other part to be lubricated and is fastened-in position by the engagement of the loop B with the lip u. \Vhen the lubricator is applied as statcd, the band A will be placed under slight tension and the swab will be pressed against the pistona'od, with the result that there is no liability of casual movement of the lubricator on the rod. It will also be noted that when the loopB is disengaged from the lip a the ends of the band A will spring apart, and the lubricatormay then be quickly and easily removed from the rod.

Incident to the use of the lubricator oil is supplied at intervals to the cups G, and it will be readily appreciated that such oil will pass from the interiors of the cups through the slits (Z, the hollow arms 0, and the ducts w in the order named to the wick D, by which it will be absorbed and from which it will be supplied to the swab E as needed. The oflice of the swab is to apply the lubricant to the piston-rod or other part to be lubricated, and it will be noticed that the use of the said swab in connection with the wick assures a plentiful supply of lubricant to the rod and yet precludes dripping and waste of the lubri' cant.

\Vhen the wick D and the swab E of my novel lubricator become deteriorated through use, they may obviously be readily removed and replaced by a new wick and swab, so it will be seen that the major portion of my improved device will last for an indelinite period. It will further be noticed that when the wick and the swab are removed, as above suggested, the lubricator may be readily cleared of collected sediment and otherwise thoroughly cleaned.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a lubricator, the combination of means for holding the lubricator on a rod, a wick carried by said means, means for supplying lubricant to the wick also carried by the firstmentioned means, and a swab surrounding the wick.

2. In a lubricator, the combination of means for holding the lubricator on a rod, a wick carried by said means, a lubricant-holder also carried by said. means and connected with a wick, and a swab surrounding the said means and the wick.

3. In a lubricator, the combination of a band provided with means for fastening it about a rod, one or more lubricant-cups carried by said band, a swab surrounding the band, and one or more conduits intermediate the cup or cups and the swab.

4. In a lubricator, the combination of a band provided with means for fastening it about a rod, one or more lubricant-cups carried by said band, a wick arranged at the inner side of the band, one or more conduits for carrying oil from the cup or cups to the wick,

and a swab surrounding the band and the wick.

5. In a lubricator, the combination of a band provided with means for fastening it about a rod and having a port or duct, an oilcup disposed at the outer side of the band, a hollow arm intermediate the band and the cup and connecting the port or duct of the former and the interior of the latter, and a swab surrounding the band and also surrounding the said hollow arm.

6. In a lubricator, the combination of a band provided with means for fastening it about a rodand having a port or duct, an oilcup disposed at the outer side of the band, a hollow arm intermediate the band and the cup and connecting the port or duct of the former and the interior of the latter, a wick arranged at the inner side of the band, and a swab surrounding the band and the wick and also surrounding the said hollow arm.

7. In a lubricator, the combination of a band, means for fastening said band about a rod, absorbent material surrounding the band and also surrounding a wick interposed between it and the band, the said wick, and an oil-cup carried by the band and provided with means for supplying the wick and the absorbent material with lubricant.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
