`j-I lia-ve.avoided the objectionsfinherent ,in

the previously,.usedffspindlebases, as above described, Aby providing anew form of base, tha-,characteristics andy y,salient Ifeatures off which are" described in the following ,speciii cation with-g reference. to the :drawings Aherewith ligiirnished, inlfwhich Ifhave yillustrated the preferred l. embodiment? 'of vfthe `ir'ivention as applied to a ball bearingl spindle. The invention consists in the novel characteristics oit such base, and the combination thereof with a spindle blade and its whirl, hereinafter Il ully described and claimed.

ln the dra-wings,-

Fig. l is a sectional view ot a complete spindle including` a base in which the present invention is embodied, a blade, a. driving whirl it'or the blade, a stop pin and a cover plate; i p

Fig. El is a. plan view of the base;

lllig. 3 is a plan view ot the cover plate; and

`Figi it is a vertical cross section of the cover plate.

Lilie reference characters designate the same parts wherever lthey occur in all the ligures. j

a, represents thebase, b the blade, and c the whirl applied to the blade. The base is provided with a lateral flange d. by which it restson the spindle carrying rail ot the spin ningr frame, the lower part ojli the base proj ccting through the rail. being' screw threaded in the part e to receive a nut :for clamping it to the rail in the usual way. The interior ot the base is drilled to torni an internal chamber or socket f to receive the foot of the blade and a step bearing g. j In the present design, the upper part of the base is enlarged to receive a sleeve la. forming; lthe outer race of a ball bearing e', ojt the character described in my prior appli fation, Serial No. 750,212, previously reit'erred to; but this is a ldetailwhich may be t'leparttal from; and the essential characteristics ot the invention may be applied to the base adapted for a spindle of the common ji1urnalfbearing type. The proportions of the spindle blade. base and whirl, and the relation oit the whirl to the tlang'e, are, or may be, substantially the same as those eXist ing' in spindles ot the type and designs now in general connnercial use, except that the tlange extends at one side ot' the spindle to a much greater distance than is usual with sueh spindles.

ln the upper horizontal side of the flange (Z is an open pocket j to receive oil, and from the inner' vall oi this pocket; a hole leads to the chamber f. The pocket and the outer boundary olf the flange are preferably concentric with the blade, as shown in plan view by Fig. i2. As previously7 stated, the flange Z projects at one side of the spindle to a much greater distance than usual hereto'lore, and the part so projecting' is that in which the oil pocketis contained. It extends so :tar that the pocket is entirely outside ot the circumterence ot the whirl, or, in other words, .it is farther away from the axis oit the spindle blade than the circumference of the whirl. Then the spindle is applied to the spinning rail of the spindle frame, the base is set with the oil pocket on the outside or front, (considering, as the front the side ot the spindle, at which the attendant stands when oiling it or performing other duties in corner-tion with the machine). The sides oit the base toward adjacent spindles may be flattened. as shown in Fig. 2, in order to permit placement ot spindles as near together as permitted by other factors, and the oil pocket may he as long as the distance between these sides less the space needed to provide contininnf walls at the ends of' the pocket.

The hase provided at the rear with. a luar Z to support a pivot pin m. by which a plate o is connected to the base. The plate o serves as a cover :tor the oil pocket and also as a holder for a stop pin p erdoti'er guard; having a rear extension q in which'the pin is mounted. The central part ot the plate is open, or formed with an aperture, to admit the risingy part' oit the base, which provides the hearing for the blade, and the spindle whirl. The rear part o'l.z the aperture. designated as i' in Fig. il, is complemental to the lug' Z. and elsewhere the aperture is large, enough to permit the plate, when raised, lo clear the lower flange of the whirl and to be raised high enough to fully uncover the pocket, as shown bydotted lines in Fig. l, giving' a clear `view of it to the attendant and leaving1 ampleroom for pouring oil into it. The forward part oi theplate is of proper dimensions to overlie and 'tully cover the oil pocket j and to extend at its outer rim somewhat beyond the adjacent part of the base. itlange tl. j j

The stop pin y) rises from the cover plate at. the rear ot the whirtavhere it otlei's no impediment to tying and applying the drivine' band, and its upper end is bent over so as to overlie the upper flange thereof and prevent the bladebeing renioved 'from the base when the bobbin dotted. But when it is necessary to remove the hladegthe stop pin can be shifted out oil. the way of the whirl by slightly raising!` the' forward side ot the plate.

In calling' the member o a plate, l have not intended to impl;Y a limitation as to its torni. In its jfu'eierred torni, as here shown, it con'lpletely surrounds the anis ol` the spindle. but it may be otherwise formed. That part. ol it which lies at the 'tront of the hase and covers the oil pocket is olf short height or thickness and substantially flat on the upper side. The upper surface ol. the plate. as to this part. is thus located at a substantial distance below the bottom of the whirl, and leaves an open unobstructed space in which the risingpart of the base above the` llanee is exposed. j

The part which l have just designated as the rising,lr part ot the base is the part which receives and surrounds the sleeve 7b, pre* Mue v'iously mentioned, and. is surrounded `at rits Vzend the lower hpartei itlie Whirl. It provides a stationary surface'gexposed at the front side .of thespindle, over :which the endsxoit .the drivingb'and may :be 'passed and A'against@which the :band may be .-su'p vported While :these yends are '.tifedtogether,

' Wherefore flthis part of :theflbase may be termed 1a. :band :suppe-rit. This 'band support is approximately equal 1in radiusto lthe :bottom of ythe yband. receiving groove 1in ,the whirhithus'enabling a band vto be :tied "with y suicienttensionifor:drivingthe'ivhirh Tihe material used lfor driving !"bands is suiiiciently :elastic toy vpermit the band, after Ibeing so tied, toghe passed 'over the outstanding 3lower flange ot'V the wlifi-r'l. This band f support -enables the driving :band fot :any

spindle to be tied `without stopping the entire spinning frame'in which the spindle is mounted, since the stationary fsurface 'of the support .enables .the operatorto hold the band stationary @while tying. the knot, even thoiwli fthe driving drum, :around whichfrthe bandnfallsofpasses, continues Vin rotation.l

The same support als'oserves as a means tor temporarily holding .the band .when .the

- blade and whirl are removed Vfor itu-rniiig no y the band todr'ive .the spindle-inthe opposite direction. Its presence in all` thev spindles of a spinning :trame greatly facilitates, and

'shortens the time necessary l"for, changingA the bands to driveA all the spindles oppositelyy to their previous direction of rotation.`

It will be understood from the" foregoing description that the base can ybe cast in a vertical position, for it has no projections Which would prevent drawing of the pattern from either part of thesandmold in a longitudinal direction. This allows thev heavier metalloids ot' the molten iron to settle symmetrically around the axis of the base vand enables the subsequent drilling the spout of his oilv can to the mouthof the Oil stem in the prior type spindle.V Thel danger of overilling the pocket is largely avoided,4 because the' attendant, byV noting when the oil ceases `to drain out of the pocket as he pours it in, and beginsto lill f up, can tell that the interior of the base is full of oil, in time'to cease pouring before he has overtilled the pocket. kSuch oil. as
