Application October 31, 1939, Serial No. 302,244
In Great Britain October 20, 1938 Y Claims.
'Ihis invention relates to improvements in spindle assemblies for textile machines for spinning, winding and like processes, and has particular reference to means for lubricating the spindle.
5 The method of lubrication according to this invention, in which the quantity oi oil required is comparatively small, is applicable to most highspeed spindles running at speeds up to 20,000 revolutions per minute.
l0 The invention provides a textile spindle assembly which comprises a bolster rotatably supporting a vertical spindle and spindle wharve, a bolster holder in which the bolster is non-rotatably mounted, and an impeller iixed on the lower part of the spindle within the bolster and adapted to force oil in a circuit around and through the bolster to lubricate the spindle bearing surface within said bolster.
The impeller is conveniently mounted on the 2o spindle near the foot thereof and opposite one or more openings in the wall of the bolster so as to forcey oil around or over the external surface of the bolster to the top thereof, whence it gravitates to the bottom of the bolster.
In the preferred embodiment illustrated in the accompanying drawing which shows a spindle assembly primarily intended for use on a machine for spinning, twisting and throwing pure silk, rayon or other yarns, the wallof the bolster holder extends upwardly beyond the top oi the bolster to constitute an annulus around the spindle at its upper bearing position, into which annulus cil is lifted by the action of the impeller at the spindle foot and from whence it gravi- :l5 tates to the interior of the bolster.
In the drawing:
Figure 1 is a vertical sectional elevation through the spindle assembly.
Figures 2 and 3 are horizontal sections on lines II-II and Ill-III respectively of Figure 1, on an enlarged scale; and, Y
Figure 4 is an outside elevation of the spindle bolster employed.
In the construction shown, the spindle I is 4.3 rotatably supported at its foot end on a pivot point or cone 2 in a conical seating 3 provided at the bottom of the socket 4 of a bolster 5, the lower portion of the spindle I being tapered and guided in the mouth of the bolster socket 4. The 50 bolster 5 is supported at its foot end by the base 6 of a bolster holder 'I and by means of a shoulder 8 within the holder 'I upon which seats the underside of the enlarged head portion 9 of the bolster 5. The holder 1 is screw-threaded at 55 its base for attachment to a spindle rail (not shown) and has a flange I0 carrying a springloaded tiltable stop i I which limits upward movement of the vhanged wharve or pulley I2.4 This Wharve or whirl I2 is keyed to the spindle I and houses the upper part of the holder 1. 5 I Near the foot of the spindle, and on said spindle'l is mounted in' known manner a runner or impeller I3 provided with projecting blades (see especially Figure 3), an oil discharge opening I4 being provided in the wall of the bolster 5. 10 The quantity of oil required for effective working is small, as it need not reach far above the' level of the impeller on the spindle. As the spindle I rotates, the impeller I3 forces oil through said opening I4 into the annular space I5 withl5 in the holder I around the lower part oi the' bolster 5, and thence up through one of a number of channels I6 (two channels are shown) cut in the external surface of the bolster 5 into the annular space I1 formed above the - bolster 5 and 20 the projecting wall of the bolster holder 1. From thence some oil gravitates around the spindle I to the bottom of the bolster socket 4, while any oil in excess of that which passes into the bolster socket 4 returns down through one or other of 25 the channels I6 to the bottom I8 of the holder 1, which constitutes an oil-sump or oil-space I8 and communicates with the bottom of the bolster socket 4 by means of a passage I9. The bolster 5 is held against rotation within the holder I by 30 means of a Tshaped spring 20, the bar of which engagesI within a peripheral groove 2I cut in the bolster head 9, while the stem of the spring 20 engages within a keyway 22 provided in the interior of the holder 1. (see Figure 2 especially). 35
The arrangement of parts shown checks any tendency for the oil to creep up the spindle higher than the top of the bolster, thereby obviating the possibility of oil being atomised by the high speed of the spindle and thrown on to the filaments of 40 the yarn.
We claim:
1. In a spindle assembly, a verticalv spindle having its lower portion tapered downwardly, a Vertical bolster wherein said spindle is rotatably mounted, a bolster holder provided with a central bore wherein said bolster is mounted, the wall of said bolster being provided with an aperture extending therethrough near the bottom thereof,
said bolster and bolster holder comprising oil path channel means for conducting oil upwardly from. said aperture between said bolster and said holder and across said bolster to said spindle, and a projecting blade runner mounted on saidspindle in the space between said spindle and said u bolster provided by the tapering of saidspindle v ster provided by the tapering of said spindle and in register with said aperture.
2. In a spindle assembly, a vertical spindle, a vertical bolster wherein said spindle is rotatably mounteda bolster holder provided with a cen-l tral bore wherein said bolster is mounted, the
. wall of said bolster being provided with an aperture extending therethrough near the bottom thereof, said bolster being provided on its eX- ternal surface with a channel, oil passage means including said channel extending from said aperture extending therethrough near the bottom thereof, said bolster being provided on its external surface with a channel, oil passage means including said channel extending from said aperture upwardly to the top of said bolster, and a projecting blade runner mounted on said spindle in the space between said vspindle and said boland in register with said aperture.
4. In a spindle assembly, a vertical spindle having its lower portion tapered downwardly, a
vertical bolster wherein said spindle is rotatably mounted, a bolster holder provided with a central bore wherein said bolster is mounted, said bolster holder projecting upwardly above said bolsterto form an annular space thereabove adapted for the ow of oil therethrough, the wall of said bolster being provided with an aperture extending therethrough near the bottom thereof, said bolster and bolster holder comprising oil path channel means for conducting oil upwardly from said aperture `between said bolster and said holder 'and across said bolster to said spindle, and a projecting blade runner mounted on said spindle in the space between said spindle and said bolster provided by the tapering of said spindle and in register with said aperture.
5. A spindle assembly according to claim 2, said oil passage means further including an annular space formed within said holder around the lower part of said bolster.
