ROTARYLUBRICATOR.'

SPECIFICATION forming part of Letters Patent No. 324,864, datedAuguEtZS, .1885.

T0 all whom it may concern:

Be it known that I, DUNCAN L. MCCORKIN- DALE, a citizen of the United States, resi-ding in the city of Troy, in the county of Rensse- 5 laer and State of New York, have invented certain new and useful Improvements in Rotary Lubricators i'or Journals, of which the following is a specification, reference being had to thcaccompanying drawings.

My invention relates to improvements in lubricators that are adapted to contain lubricating material, and to be rotated by peripheral contact with a revolving journal to be lubricated.

The general objects of myimprovements are to provide means for regulating the rate of escape of the lubricating material from the lubricator to the journal as may be required by journals of different sizes or of different 2o heating tendencies or by lubricants oi' different qualities or degrees of fluidity, to provide simple means for lubricating the journals of rotary lubricators, and to furnish a cheap and quickly-detachable holder for rotary journal- 25 lubricators.

In the accompanying drawings, Figure 1 is an isometricalrepresentation of one oi" my improved lubricators applied for use to a journal. Fig. 2 is an isometrical drawing of one 3o end portion of the saine lubricator, the outer porous covering being removed. Fig. 3 is an isometrieal view of the other endv portion of the same lubricator, showing a section thereof at the line y y in Figs. 4 and 5. Fig. 4 is a 3 5 side elevation ofthe same lubricator but without a porous covering.- Fig. 5 is a central longitudinal section of the same lubricator in the plane Vor" the line .e z in Figs. 2, 3, and 4. Fig. 6 is a central longitudinal section at the 4o line w w in Fig. 7 of a lubricator that enij braces a portion ot' this invention, and Fig. 7 is a transverse sect-ion of the same at the line .r ai in Fig. 6.

Like letters refer to similar parts in the dit'- 45 ferent iigures.

- A is a hollow cylinder furnished with heads B Bf, and adapted to contain lubricating 1na terial V, Fig. 5, and having in its circumferenceanaperture or apertures c to permit the 5o gradual escape therethrough of the lubricat ing materialto ajournal, U, Fig. 1, to be lubricated.

For regulating the rate of escape of the lubricating material from within the cylinder A through its aperture or apertures c, I furnish the cylinder with an adjustable cut-off, G, arranged either within the cylinder, as shown in Figs. 6 and 7, or exterior thereto, as illustrated by the other figures.

In the lubricator shown by Figs. (i and 7 the cut-off O has perforations d corresponding to the perforations c through the casing A, and has at its ends screw-stems e e', which extend and iit through suitably-arranged holes in the heads B B', and are furnished with screw-nuts g g,which iit closely upon the screw-ste1ns and are screwed tightly against the heads. By loosening one and tightening the other of the .two nuts the eut-oft C can be moved and adjusted lengthwise within and closely along the casing A, so as to thereby open or close the apertures c to any desired extent, and thereby control the rate of escape of lubricating material through those apertures.

The cut-off Cin Figs. 6 and 7 may be aperforated bar, as shown in full lines, or a hollow cylinder with open ends and fitting closely as a lengthwise f movable sleeve within the casing A, as indicated by dotted lines at /L in those figures.

In the lubricator shown by Figs. l, 2, 3, 4, and 5 the cutoff C is in the form of a sleeve which fits closely to and can be turned and adj usted circularly upon the cylinderA,which latter has a longitudinal row of pcrforations, c, Figs. 3 and 5.

The sleeve or cut-ott` C in Figs. 2, 3, 4, anal 5 has a series of perforations, d, which are y arranged in circumferential rows that are at the same distances apart as the perforations c and in lengthwise rows which have different numbers of perforations, and in Fig. 4 are numbered l 2 3 4 5 6 7 8 9, respectively.

In Figs. 4 and 5 the sleeve C is shown ad justed with its lengthwise row of iiveperforations d in coincidence with live of the perlorations c in the body of the lubricator. The sleeve is adapted to be turned and adjusted so as to have any desired lengthwise row of its perforations in coincidence with the row of perforations inA the cylinder, and thereby permit more or less of the lubricating material to escape through such perfora'tions in a given time. The sleeve C in Figs. l, 2, 3, 4, 5 can be adj usted circularly and retained in position upon the cylinder A `by various means, but as an improved device for that-purpose I have 011 one head, B, of the cylinder a row of stops or 1o notches, z', spaced and nu mbered in conformity with the lengthwise rows of perforations in the sleeves, as indicated by Figs. 1, 2, and 4, and have in proper position on the sleeve a v stop or spring-catch, j, Fig. 2, adapted to be -readily engaged with and disengaged from each of the stops or notches t' by hand.

The above-described adjustable lubricators shown by Figs. 4 and 5 and by Figs. 6 and 7 can be used to apply suitable lubricating mav2o terial to suitably-shaped journals by having the outer surface of the perforated sleeve C 0f Figs. 4 and 5 or the perforated casing A of Figs. 6 and 7: bear directly in contact with the journal to be lubricated. I, however, gen- 2 5 erall y surround the perforated sleeve C of Figs.

2, 3, 4, 5 or the perforated casing A of Figs.

6 and 7 by porous or fibrous material K-as,

for instance, a layer or layers of loosely felted or woven fibrous fabric-secured or 'wound aroundthe said sleeve or casing, so that such porous or fibrous covering shall absorb the liquid or semi-liquid lubricant passing outward .through the perforations c and d, and

thereby -distribute the lubricant along and around the whole circumference of the lubricator and journal to be lubricated as the lubricator is revolved by the surface contact with the journal.

In Figs. l, 3, and 5 the porous or absorbent 40 covering K is shown in full lines, and is indicated by dotted lines in Figs. 6 and 7.

In using the lubricator, it can be held so as to be revolved by surface contact with the upper, lower, or any other exposed side of a revolving journal by various well-known de vices. As an improved means for that purpose,I make the lubricator with small conical or pointed journals Z, and provide a holder, M, which is adapted to be hinged, pivoted, or similarly secured to a xed support, essentially as indicated at a in Fig. 1, and has arms o, formed. with interior depressions or perforations, into which tit the small conical or pointed journals Z of the lubricator, as illustrated in Fig. 6, one or each vof said arms being elastic so as to thereby securely hold the lubricator by its journals, and allow it to be freely revolved, and also permit thelubricator to be at once removed from and replaced inthe holder upon merely springing outward one or each of the arms` of the holder by hand.

To provide means for lubricating the small pointed or conical journal Z of the lubricator, 55 I form the latter with a perforation or passage, as at p, from the lubricantchamber to the surface of the pointed or conical journal,

and have a wick, q, extending outward from within said chamber closely through said passage or perforation, substantially as shown 7o by Figs. 5 and 6.

ln Fig. 5 the head B is detachably secured to the cylinder A by male and female screws thereon, as at r, for convenience in introducing material and in placing the sleeve or cut- 7 5 off C upon and removing it from the cylinder.

In Fig. 6 the head B is shown detachably secured to the cylinder A by screws s, to permit the ready insertion and removal of the cut-off C, and is furnished with a removable screwplug, t, to allow lubricating material to be introduced into the chamber of the lubricator.

I am aware that a cylindrical journal-lubricator adapted to contain lubricating material, and to be rotated by peripheral contact with a revolving journal to be lubricated, and having its circumferential casing perforated and surrounded by a felt or porous covering, is not new.
