THOMAS WRIGLEY, OF TODMORDEN, ENGLAND.

SPINNING-SPINDLE.

SPECIFICATION forming part of Letters Patent No. 492,080, dated February 21, 1893.

Application iiled April 22, 1892. Serial No. 430,187. (No model.)

To all whom. it may concern:

Be it known that I, THOMAS WRIGLEY, of Waterside House, Todrnorden, in the county of York, England, have invented a new and useful Spinning-Spindle, ot' which the following is a specication, reference being had to the accompanying drawing, making a part hereof, which is a lengthwise section illustrating my spindle, and in which A is the supporting tube, B the spindle, O its sleeve whirl and D apost, confined within the supporting tube, and entering a bore in the spindle.

I have shown the upper end of the supporting tube with a bushing o, which I prefer to force tightly into the upper part of vthe supporting tube; but which may, if preferred be adapted for a slightlateral motion. Although it is indifferent whether this bushing a, be tight or loose in the supporting tube, yet the bushing is desirable; for it acts as a guide when the spindle is put into the supporting tube.

I have shown the bushing a as driven tightly into the upper part of the supporting tube, but with two grooves lengthwise so that e any oil which may be thrown off of that part of the spindle just above the upper end of the bushing, may percolate back into the supporting tube. The lateral or bolster bearing for the spindle is practically the side of the post and the lower end of the tubular part of the spindle and the step bearing is the upper end of the post and the closed end of the tubular part; in practice I have found it preferable on the whole to have the upper end of the post D practically in the plane of the band pull, as shown in the drawing, and to have the hollow part of the spindle B, eX- tend well down,the proportions shown being those preferred.

tilt when in rapid revolution, as required by the unbalanced load of the bobbin and the yarn upon it, the lower hollow part of the spindle will not remain concentric with the post D; although the lm of oil always between the interior of the tubular part of the As the spindle will tip or spindle and the exterior of post D serves as a cushion, and prevents grinding and heating which might otherwise ensue from contact o'f the spindle with the side of post D. In practice I prefer tomake vent holes b in the hollow part of the spindle B, to allow circulation of oil. The post D may be driven firmlyinto la cavity made for it in the lower part of the supporting tube, or may have slight play in that cavity, so that it does not revolve with the spindle.

I have shown the supporting tube with a middle sleeve a projecting well up into the sleeve whirl O, as usual; but in addition I provide the supporting tube A with a shorter sleeve o2, which extends up into a deep groove O formed in the lower part of the whirl O. This feature is desirablein all forms of sleeve whirl spindles, for if the space between the Sleeves a a2 be wiped out from time to time no oil can be thrown out by the whirl.

What I lclaim as my invention is- 1. In combination a spindle tubular at its lower end; a sleeve whirl; a supporting tube whose upper portion extends up into the sleeve ol' the whirl; and a post Whose upper end forms in connection with the inner end of the bore the step or end bearing of the spindle and whose lower portion forms in connection with the mouth of the bore the bolster or side bearing of the spindle; all substantially as set forth.

2. A spindle,a supporting tube with the long middle sleeve a', forming an oil receptacle, and also with a short outer sleeve a2, forming a drip cup for oil; in combination witha sleeve Whirl surrounding but not revolving upon the middle sleeve a and grooved at its lower end to receive the outer'sleeve a2, all substantially as set forth.

In testimony whereof I have hereto affixed my signature in presence of two witnesses.

THOMAS WRIGLEY.
