T0 (LZ/Z whom it may conce/"71,:

Be `it, known that I, HENRY CLINTON VAUGHN, a citizen of the United States, residing at Jefferson City, Cole and Statel of Missouri, have invented new and useful Improvements in Oil-Cups, of which the following is a specification.

The invention relates to an improvement ranged to automatically discharge its contents under the jarring iniiuence of the operating machinery.

' he main object of the present invention is the production of a cup havingV an adjustable discharge-opening which is normally closed when the machinery to which the cup is applied is at rest and'which is automatically opened to permit discharge of the contents of the cup under the jarring iniiuence incident to the operation of the machinery.

The invention in its preferred form will be described in the following specification, reference being had to the accompanying drawings, whereinj Figure 1 is a view in elevation of my oil- Fig.2 is a vertical central section of the same. Fig. 3y is a transverse section ofA the feed-screw. v

Referring to the drawings, 1 represents the base of the cup, comprising a cylindrical portion provided at its upper end with a concentric vertically-extending flange 2. The base portion is centrally formed with a longitudinally-arranged feed-channel 3, extending through the base portion and threaded at its lower end, as at 4, to receive the feed-screw 5. Immediately above the threaded portion 4 the channelis diametrically reduced to provide a valve-seat 6, with which a ballvalve 7, loosely seated in thel channel, is arranged to coperate. f l

Feed-screw 5 is provided` with the usual conical seat 9, formed in the channel 3 below the seat 6. A longitudinal groove 10 is formed in the feed-screw to permit passage of the oil from the channel 3, as will be hereinafter explained.

Afeed-tube 11 rises centrallyfrom the base 1, bein preferably formed integral therewith, a ore of the tube registering with the channel 3.

A body 12, preferably a glass cylinder, is

in the county of f Seated at its lower end within the iiange 2 of the base, preferably seatin u on a gasket 1E; to" revent leakage. rlhe o -y is concentric witI the tube 11 and spaced therefrom to provide an oil-chamber 14, as is'usual in del vices of this character. 11 is provided with a series of laterally-extendin openings 15, terminally communicating wit the interior of the bore and with the oil-chamber14, whereby oil from said chamber is admitted to the tube. The'upper end of the body 12 is engaged by a cap-plate 16 body and provided with a gasket 18, engaging said body edge toprevent leakage.`

rlhe upper end of the tube 11 projects centrally through the ca -plate and is engaged by a lock-nut 19 and y a headed screw 20,

having threaded engagement with the intei rior of the tube, as clearly shown in Fig. 2.

The lower end of the base 1 is reduced and threaded at 21 for engagement with the machinery above the bearings and provided immediately thereabove with an angular portion 22 to receive a wrench or other tool ,for screwing or unscrewing the cup. With the parts constructed and arranged as described and the cup in place above the bearings the vibrations of that portion of the machinery to which the cup is attached will cause more or less movement of the ballvalve 7, which is thereby continually moved to and from its seat 6 and insuring a constant supply of oil to the bearings, it being understood that' the oil iinds its way from the chamber 14 through the openings into the tube 11, pastthe valve 7, and lengthwise the feed-screw 5, through the channel 10 therein. Immediate the operation of the machinery ceasing the valve 7 returns to its seat 6 and instantly shuts off the supply of lubricant.

The cup described is automatic in operation, feeding oil to the bearing when only the shaft therein is in motion and cutting 0E said iiow immediately the movement ceases, avoiding waste of the lubricant and insuring its use only when re uired.

It will be noted t at the supply of lubricant fed to the bearing may be regulated by a The wall of the tube I IOO longitudinal adjustment of the feed-screw 5 65 of suitable dimension having a depending flange 17 to receive the upper edge of the I claim as new, and desire to seoure by Letand a feed-screw having threaded connection ters Patent, is` with the walls of the channel arranged to oo- -A lubrioator comprising a base, a oylinoperate with said valve-seat, said feed-screw drioal body supported on the base, a feedbeing formed with a longitudinal groove. 5 tube within and in communication with said In testimony whereof I alix my signature 15 body, a feed-channel in the base and in eoinin presence of two witnesses.
