The primary object of the invention is to im prove the running qualities of the spindle and stood upon reference to Figure 5. Carried by the spindle blade 23 immediately above the upper end of the extension I! of the case 18 is a whirl reduce wear to a minimum. ' Y ‘ designated generally 25 which comprises a cylin -~Among its features my invention embodies a drical body 28 carrying at its lower end an out spindle case having ‘heat radiating ?ns and a wardly extending annular ?ange 21, and at its . whirl on the spindle and encircling the heat upper end a hub 28 which is attached to the spin radiating ?ns of the spindle case so that as the whirl is driven to rotate» the spindles draft of 10 dle blade by a drive ?t so that when the whirl is rotated the spindle blade will be rotated in air will be created over the heat radiating ?ns unison therewith. As shown the upper end oi.’ to. cool the spindle case and spindle. the hub 28 isi'ormed with a pad or seat‘ 28 the Other features include a single ball thrust upper surface oi’ which rises abovethe general hearing against which the bottom ‘end of the. level 0! thephub 28 so that ‘when a bobbin is spindle runs‘. mounted on the upper end of the whirl it will be Referring to the drawings: ,- . held in spaced relation to the hub. Formed at Figure 1 is a side view of a textile spindle the junction of the side walls 28 of the whirl and embodying the features of this invention, ‘ the hub 28 are upwardly and outwardly extend Figure 2- is a top plan view of the spindle illus 20 ing passages 30 the purpose of which will more trated in Figure 1, _ ‘ fully hereinafter appear. The lower. end of the Figure 3 is a bottom plan view of the spindle, whirl is spaced from the upper surface of the Figure 4 is a vertical sectional view showing ?ange H as will be readily appreciated upon ref certain portions in elevation to more clearly illustrate the details oi‘ construction, 7 erence to the drawings. In operation it will be understood that as the whirl 25‘ is rotated the spindle blade 23 will ro tate in unison therewith and due to the rapid motion of the passages 38 a draft of air will be. drawn upwardly between the heat radiating ?ns l8 and the innerface oi the wall 26 oi’ the whirl and discharged outwardly through the passages 38, thus effecting a cooling of the spindle. While it is perfectly possible to cool the spindle as previously described, I ?nd it advantageous 35 to enclose the fins l8 in a suitable sleeve 8 l' which Figure 5 is a vertical sectional view through 35. the spindle, , . Figure 6 is a transverse sectional view taken substantially on the line 8-6 of Figure 5, and Figure 7- is a transverse sectional view taken substantially on‘ the line 'l—-,'| of Figure 5. Referring to the drawings in detail, a spindle case designated generally Ill comprises a shank l I having a screw threaded end l2 for the‘ re ception of a nut l3 by means oi’ which the spin dle case is clamped- to a spindle rail against a flange H formed on the spindle‘ case body in termediate. its ends. That portion oi.’ the spin dle case body 15 which projects above the ?ange ' is of a diameter to avoid contact with the ?ns so as ‘to permit the free ?ow of air upwardly and around the heat radiating ?ns. This sleeve is dle case is a bore I‘! which is provided adjacent - These openings are to provide ventilation so- that provided adjacent its upper and lower ‘ends with “ is provided with annular heat radiating ?ns l8.
