Letters Patent No. 103,170, dated May 17, 1870.y

. xmnovnn LUBRICATQR.

\ be Schedule referred tain thon Letten PatentA and making part of the same.

Be it' known tlrat"I, GREGORY Gannon, ofthe city of Albany, in thecounty of Albany and State of New York, 'ha`vc invented a. new and useful Improvement in Lubricators; and I do hereby`declare the following to lie` a full,'clear', aud exact description thereof, which will enable those `skilled in t-he art to make and use the same, reference being had to the accom-4 1 panying drawingr forming -part of `tlrs specification,

` and runs downto `the journal.

` If the lubricating cup is attached to the hub of a loosc-pulley,so` that it is carried round by the same, provision must be made to retain the lubricating malterial down at-the bottom of the cup, and to eti'ecttlrisjpurpose, a follower is litted into the cup, which bears upon the lubricating material, being pressed i down by a spring, a portion .of which is inclosed in a tube extending from the, top of the cup, said tube being made of such a length that rooin is obtained for a springotl `sulicientjlength to act upon the follower with the requisite amount of power, whatever the position of said follower in the cup may be.

4In the drawing-` -V The letter A designates a 'lubricator or oilcup, `which is provided with screw-shank a, by means of which it can be s'ec'nredjriiv `the hub of a loose pulley, or in any other article toxwhich said luhricator is to 'l be attached.

Through this screw-shank extends'a pipe, b, which is made ofcopper, or' other good conductor of heat,

, andthe outer end ofwhich is`intendedto rest loosely u'pon the journal `of the shaft which is to be lubricated, `while its innerend bears a perforated' concave disk, c, on which the lubricating material is packed, so that it serves to keep the 'pipe b in contact with the journal, and also to-diuse the heat communicated by the journal to the pipe, throughout that portion o l' the lubricating material which is in contact wit-lr it.

The lubricating material scompou'nded in such a nranner that it melts at a temperature of about 110, and that it will not become liquid at the ordinary temperat-nrc, butif the journal begins to heat, and the heat is communicated through the pipe b and disk c to tire-lubricating material in contact withv said disk,

a portion thereof is melted and the journal is lubricated.

In order to insure a correct operationof this-device, therefore, it is necessary that the lubricating material shall be held in contact at all times with the disk c.

This object is attained by a-follower, d, which is fitted into the cylindrical body of the vcup A, and depressed upon tlrclubrioatingmaterial by means-of a.

spiral spring, e'. This spring must necessarily be of such a length that it is capable to keep the follower down upon the lubricating material throughput the entire depth of the cup A, and in order to elect this purpose, a tubular projection, j, has heeusecured vto the top of the cup A, said tubular projection being large enough to admit the spring, as shown i-n llrc drawing.

By this arrangement the follower is kept n"`contact with the lubricatin material, even if the cup A is secured in the hub oa loose pulley, and carried round with lthe same, the spring being made strong enough to counteract the 'centrifugal force'of the follower.

What I claim as new, and desire to secure by Letters Patent, is v I 1.'An oil-cup or Iubricator, consisting of a frame A, follower-11, spring e, disk c, and pipe b, combined, substantially as and for the purpose described.

2. The combination of follower tl, spring e,disk c, frame A, with a top carrying a tube, f, substantially as described. i A

This specification signedby me this 13th day' of W. HAUFF, E. F. Knsrnrunnen.`
