VERTIGAL BEARING.

essees,

To all whom it may concern; I

Be it knows that I, CHAeLEs 2i. DILLoN, a citizen of the UnitedStates, residing at Centiin, in the county of Stark "and State of ()liio, have invented certain new and useful improvements which the following is a specification. The inventionlrelatesto the vertical beerings for an electric motor combined with a suction fan, asin a vecuur iclcening machine I In machines of this type, bell beep, ings are preferably used in What might loc celled a lubricating chamber; and, by reason.

"of the rapid. rotetionrequired of the rotor shaft, on which the fan is secured,-a-ricl also reason of the suction caused by the repiclly rotating fan, cliilioulty is experienced in properly retaining-the oil in the lubricating chamber, This (iiificulty is overcome liyfitlie preferred embodiment of the improvement illustrated, in the accompanying drawings, forming part hereof, in WlllClh 4 Figure l is en elevation section 01 mi electric motor combined with a, fan blower; and Fig. 2, a section of the lower rotor hearing Similar numerals refer vto similar parts throughout the drawings. The motor includes the upright case I formed on or connected with the upper side gas of the blower case 2; each. coil of which motor case is formed or secured a, bearing; case 3 or 3 forming the lubricating chamber 4% or i, in which is located the lower end op perhecringbolls 5 or 5 for the, rotor-spindle The case sleeve 7 oi 7 isl-securecl in the aperture 8 or 8 in the it ttom.

nut 1 or 14; screwed on the lower end of the sleeve; and, when the annular nut is atljustecl tightly against tie lower end of the race collar, it is preferably locked in this position as by means of the pin 15 entered into registeringholes bored through the oilpuler out into. the spindle sleeve, and held 111 place by the spring-role; 16, secured by its resilience in the annular groove 17 formed around the annular nut, which spring is out or severed onone' side as at 18 to permit its being placed in position and remotecl therefrom. The outer race-ring '19 or 19 is telescopeci in the bearing case 3 or 3 and, if desired, maybe free to rotate therein, and the outerrac e ring 19 is supported on the interior all-'- color sho lclerc 20 provided in the bearing case, which shoulder sustains the downward thrust of the hearing. The loeering balls 5 or 5; with the. separating or spacing ring 21 or :21, are locetedfiin between, the inner and outerlrece-rings, in

the usual manner pertainingto this art.

Lubricating oil is supplied into each lubricating chamber or 4& es means ofthe iiglet tuloe23 or inlet duct 558 communicat ing with the; corresponding inlet opening 2 1- or 52 5 provided in tle outer Well the beering case and a sufficient amount-of the llllJllceting oil isprefercbly ce rrie'cl in each chain her to submerge the hearing balls Whentlie ports are etrest; audit is evitleiot oil will be thrown out the repitl r itetioii the inner recs-r outer wall of the 'l ibri Y ii. whet shows by broken Fig. 2. t L

The upper end of each lubricating chomher is preferably closed. by means of the on nuler cover- 25, the inner edge 26 of which is located adjacent to the outer side of the spindle sleeve 11 as in the lower hearing, or the spindle collar 10 as in the upper bee-r iiig, and the annular lfishepecl groovc 27 is preferably provided, in this edge for the purpose of receiving; SLH'l). may Work upward eroiiicsl the spindle sic which oil is thrown outward into the groove by cen trifupgol force {incl then runs blown into the chamber by gravity; the lower lip of the groom being prefereblymaclc it little shorter than the upper lip to more freely return of the oil.

ihmb in Ellie peripheral flange 28 is preferably pro the recc-Wziy-QEZ formed permit the 'vided on each annular cover and is adapted to rest on the upper rim 29 of the lubricating case; and the depending flange 30 is provided on each annular cover, which depending flange telescopes in and neatly fits the inside wall of the lubricator case and extends downward to the peripheral edge 31 or 31? adjacent to the upper end of the outer race collar. The inner side of this depending flange is conically inclined upward and inward from the lower edge of the flange, and the conical face thus formed constitutes part of the wall oi the lubricating chamber, and serves to deflect inward and downward such oil as may be centrifugally thrown outward and upward by the tion of the spindle-sleeve and the inner ing, somewhat as indicated by the are in Fig. 2, thus continually bathing the ialls and preventing any consider- .un nint oi oil from passing upward bethe wail oi the case and the dependoi the collar cover. Such oil, I as ii be forced upward around "m ide ol? the depending flange of the over, linds its way into the annular groove 33, which is provided in oped periphery oi": the cover, whence its way back into the lubriiber through the inwardly and ly incllmad ports 34k which are the body and depending vr into the cavity of the er above the height to i en es therein. It will b'eunder- 'or, that. the presence of the receiving eve and the ports 34; prevents the oil a .it-inuing upward. and outward over i 29 oi the bearing-case because the Oil is rree to how by gravity through the re cciving groove and the ports back into the lubr eating chamber.

'5 radial air ports 35 are provided in the lower bearing sleeve 11 preferably just above the cover of the bearing, and these supply air at the upper end of the ind largely prevent down-- i"-'..ul'l the spindle and the d by the rotation. of the l g oil or air out of the lubri eating chanil'ier. Such oil, however, asmay work upward by suction or otherwise be tween the ase sleeve 7 and the adjaor 1 cent spindle sleeve ll'or 11*, finds its way into the internalannular reeeiyiiig groove provided in the spindle sleeve, and thence is thrown centrifugally outward into the luln'icating chamberthrough the radial. ports 3'5 or 36 which are provided in the brewing sleeve. '7

in the lower bearing, where there is pres cu a. suction from the adjacent fan, the case sleeve 7 is extended upward, as distance above the radial ports V i'VHlS, from. the receiving shown, some 36 to shield the same, as much as may be, from the suction of the blower, but-in the upper bearing the case sleeve 7 need only be extended upard to the ports 36, for the reason that there is no suction to be contended with and such oil as may'find its way upward to these ports will be thrown outward by centrifugal force, and will not be sucked inward over the upper end of the case sleeve. It is also evident that no air ports are required in the upper bearing for the same reason that there is no suction in this hearing, Otherwise, the two' bearings may be and preferably are constructed substantially the same, and the description of one is a description of the other.

I claim: I 1

1. A bearing for a vertical spindle including. a case around the spindle having a lubricating chamber therein, a cover for the case having a depending flange telescoped in the case, the inner face of the flange being comically inclined upward and inward and forming part of the wall of the chamber, and there being an annular receiving groove around the telescoped periphery of the flange, and inwardly-downwardly. inclined ports from the receiving groove through the body of the flange into the cavity of the lubricating chamber above the I height to which the oil rises therein.

2. A bearing for a vertical spindle including a case around the spindle having a lubricating chamber therein, a cover for the case havin a depending flange telescoped in the case, t e inner face of the flange being conically inclined upward and inward and forming part of the wall of thechamber, and there being an annular receiving groove around the teleseoped periphery of the flange, and ports leading from the receiving groove inwardly through the body of the flange into the cavity of the lubricating chamber above the height to which the oil rises therein.

8. In a vertical bearing for a combined motor and fan blower, a covered case having an axial aperture in its bottom with an upwardly extendin sleeve secured therein forming an annular lubricating chamber, a rotor-fan spindle within the case-sleeve and having a depending sleeve extending downward around the case-sleeve, with a bearing between the spindle-sleeve and the case, and ports through the spindle sleeve at the upper end of the case-sleeve and above the case cover.
