OILING 1 Application filed June 23,

To all whom it may (on Cm.

,B 1tknown that l. AnoLrn L. Dr. Lrzniuv,

a citizen of the United States, and residing 1 at Clnclnnatl. 1n the county of llan'nlton and State of ()him have invented a new and Improved Olllng System. of which the following specification is a full disclosure This=invention relates to a machine tool oiling system and it proposes a frame organization such that oil will be autonnuically elevated from a lowermost well or point to an uppern'iost reservoir. from which it Will be gravimetrically distributed to the various wearing surfaces. largely ly-mean of conduits integral'with the main casting v or frame of the machine.

A primary object of this invention is to l it i tbs-charged directly into the well, and

create a gravimet'rical oil distril'iuting frame in which oil will be kept in continuous circulation throughout all. of lln.- \rearing surfaces, and will be ultimately (n-ma ia, an

taminated oil added to the/well oil Well and then elevated to an u i permost dlstrlbutmgpoint, and then led by approprlate channels arranged in what may he termed parallel series as distinguishcd'from multiple series, so .that each bearing releases itscontaminated oil lii-e tly t tl1r well, and not to other bearings.

v Heretoforc an oiling system has been proposed in which oil was drawn from a well in the frame of the machine and then distributed to an uppermost wearing surface, from which it was released in amore or less contaminated condition and caused to pass through another bearing, which further contaminated it, and in turn released it into. another bearing, and so on, until ultimately itwas permitted to return to the oil well after having been successively contaminated by passing through several bearings; \Vhen it reached the oil well it was of course diluted by a larger mass "of oil so that it. was suitable for reapplication' to the. bearings. This system, while not injurious on the first reached bearing, was ol jeetionahle as to sub- 1a 'terreceived oil containing an undue per centage of impurity. drop of highly (win would be so diluted as to be ha rmlcss so that a drop taken from the well would represent good lubricating material, but as soon as this "drop passed through the first hearing it. would be ontamintrtad liy a certain perccntage or iipppt'e anatierv the pcre en age of l i i Specification of Letters Patent.

These canals are supplied with oil by means of pipes and 33 that lead from pockets 22 and Q0 and which are bent into position to bring their lower ands above the upper portion: of the canuls if? and. 2?. itnother gent-insert; unit, is indicated by 34, Rildl in this instance it con-- stitutes a speed change orgnniza ion, and it is supplied with oil preferablyfrom the overflow pipe 19. The construction of these insert units will be further detailed in @011- nection with ihc vertical spindle machine. After the'oil has left.- tlie vol-ions wearing: surfaces aforesaid. it flows to the base of the .nmcliine and through in vent 36 to an oil well 37 from Wllllh it is raised by the pump ll) as aforesaid.

The vertical spindle ormlnization is shown more vlpnrly by Figs. 3 and 1, anti will. now be llesvi'iliml. 'l'hevcolumn -10 of this machine rises from a suitable base'M and tar minutes in a head eliin which is journnled the i'oi'tival spindle 43 by means of barii -14 and 45. At its upper end. an annular reservoir 46 is prm'iiled, which discharges the oil by means of an overflow 4? onto a web 48 preferably mistv integral -with the frame. The oil is conveyed to the hearing 44- by means of the groove 49 lending from the annular reservoir 46, and it'passes down the spindle to the lower bearing f1 which it is'tln-mvn off onto the main frail.

ll the oil-ring: 50, and it than flows down the inelinv and ultimately to the oil well in the base. lt is to lionoted here that-although in this instance the oil flows from. the bearing to {he hearing no llrlkil rontnminntion is exprienveil, since the in; 44- carrieshnfllly any lflflll at. all, it ne- 3 ing rolieverl from thrust. in" the hearing trough? ce io'ni hood t dams 53 and 5% that divert the oil sufficiently to cause it to flow down small, drain pipes 55, 56 and 57. p The drain 55 leads to the forward hearing: 58 of a driving shaft 59, nncl thev pipe 56 leads to the rear heating of after the oil has passed through these hearings it drinblos down the. frame of the machine toward the base and into the oil well. This column. like that of the horizontal spindle. also has :1 similar opening 24 that receives a similar transmis' sion unit 25 containing frame extensions 26 and 97 providing canals Q9 and 29 from which lead (luctsfil and 32 to the various hearings of the transmission unit. Thus,

the canal 28 provides'a pool 60,- into which oil is directlv delivered by the pipe 57 and it then overflows the edge of the pool 60 andpasses down the canal, being diver-ted at intervals by'means of dams 61 and 62 to insure its flow through the ducts 31 to the various bearings, as shown by Fig. 4. The oil overflowingthe canals 28 and 29 and discharging from the various bearings then passesdirec-tly to'the oil Well in the base.

Leading from a lowerpoint of the web 48 is an overflow pipe 63 that discharges into the pool 64 of the speed change insert unit 34, and the oil then flows over the spillway 65 and the successive dams 66 and 67 .and finally through the discharge gutter 68 down to the well. Ducts or oil holes 69 lead, to the various bearings of this unit,

and the latter in turn. discharge the contaminated oil to the central well, where it is diluted and returned to the system.

It will thus be perceived that this invention is well adapted to achieve the objects aforesaid in a simple and direct manner, and in a way preventing the admission of unduly contaminated. oil onto any of the bearings.

\Vithoutfurther elaboration, the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various applications without omitting certain features that, from the standpoint-of the prior art. fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims.
