SPINNING-AND TWISTING MACHINE SPINDLE.

SPECIFICATION forming part of Letters Patent N o. 480,984, dated August 16, 1892.

Application led November 4, 1891. Serial No. 410,818. (No model.)

T0 all whom, t may concern:

Be it known that I, HENRY F. W ooDMANoY, of Whitinsville, in the county of Vorcester and State of Massachusetts, have invented a new and useful Improvement in Spinning and Twisting Machine Spindles; and I hereby de- Clare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

Spindlesforspinningand twisting machines require to be run at high speed and so perfectly true that at all points of the reciprocation of the ring-rail the spindle'will revolve in the ring, so that ltlie yarn will be exactly concentric with the ring and the draft on the traveler at all points of the ring uniform.

The object of this invention is to secure such a spindle; and to this end the invention consists in the peculiar and novel construction of a bolster-case having a cylindrical tubular extension above the supporting-flange and oilcup, a rigid combined bolster and step-tube rigidly secured at its lower end in the bolster-case and firmly held against lateral motion at or near its upper end, and a spindle having a long bearing of uniform diameter in the bolster, provided with a sleevewhirl surrounding the upwardly-extending tube of the bolster-case and the spindle-bearing, more fully set forth hereinafter.

Figure 1 is a Vertical sectional view through the center of the spindle and its support. Fig. 2 is a vertical sectional View of the bolster-case, in which a combined bolster and step-tube are rigidly secured at the bottom in the bolster-case and firmly supported at the upper end. Fig. 3 is a vertical sectional view of the bolster and a combined step-tube and bolster firmly secured at its lower end inthe bolster-case and firmly held against lateral motion near its middle in the bolster-case. Fig. 4 is a vertical section of a bolster-case and a combined bolster and step-tube rigidly secured at its bottom and firmly held for a considerable distance at its upper part in the bolster-case.

To enable others to clearly understand my invention, I will say that my aim has been to construct a spindle-support, as near as it is practicable, of one piece and to give Y ing the bolster and step-tube.

the spindle a rigid bearing of considerable length. After a series of practical tests I constructed a number of such supports by firmly securing a rigid bolster and step-tube, bya tapering driven fit at the bottom, in the bolster-case and supporting the upper part of the combined bolster and step-tube at some place on its upper part in the bolster-case,

`so as to producea rigid support for the spindle. I havergiven the spindle a long cylindrioal bearing in this support and surround ed this bearingand the upper end of the bolstercase with the whirl.

Similar numbers of reference designate corresponding parts throughout.

In the drawings the spindle 5 is provided with the sleeve-Whirl 6 and has the long cylindricallbearing 7 of uniform diameter and extending above and below the center ofthe whirl, the foot of the spindle resting on the step 8. The spindle is su pported in the combined bolster and step-tube 9, the lower end 10 of which is slightly tapering and fits into the slightly-tapering socket 11 in the lower end of the bolster-case 12, into which it is forced or driven and so firmly secured that the bolster and step-tube and the bolster-case are practically as if made of one piece. The upper part of the combined bolster and steptube is made to fit the upper part of the bolster-case, so as to form a close sliding fit.

The bolster-case 12 has the downwardlyprojecting portion provided with the enlargement 13,which forms an oil-chamber surround- This oil-chainber is connected with the linterior of the combined bolster and step-tube by holes or openings in the Wall of the bolster and step-tube, so that the oil iows freely into the same and is thus applied to the spindle-bearings.

The enlargement 13 or oil-reservoir is connected .by means of the duct 14 with the oilcup 15, and the portionof lthe upper part of the combined bolster and step-tube in contact with the interior of the bolster-case is provided with the channels or grooves 16, by which the oil raised up by the rotation of the spindle is permitted to run down again into oil-reservoir. The bolster-oase is provided with the tube 17, extending upward above the oil-cup 15 and above the upper end of the IOO combined bolster and step-tube 9. The sleeve- Whirl extends over the upwardly-extending tube 17 and surrounds the same, as well as the long cylindrical bearing of the spindle. By this construction a firm and rigid support for the spindle is secured. The bolster-case and the spindle and step-tube combine to secure this rigidity and also facilitate the construction of the oil-reservoir to secure thorough lo lubrication.

'lhe point of contact ot' the upper end of the bolster and steptube with the bolstercase may be varied. In Fig. 1 the combined bolster and step-tube fits the bolster-case below the oil-cup. In Fig. 2 the close-fitting supporting-surface is near the upper end of the bolster and step-tube. In Fig. 3 it is shown to extend above and below the oil-cup, while in Fig. 4 the Whole of the upper length zo of the combined bolster and step-tube is in close contact with and forms a close sliding fit in the upper end of the bolster-case. With this rigid support and the long cylindrical bearing of the spindle in the same the spindle runs mathematically perfect Without the slightest wahbling or uneasy motion. It runs perfectly with a tight band and as perfectly with a slack band. The ordinary difference in the bobbins or in the yarn-load 3o does not altect the running of the spindle, and this spindle essentially differs from all the `spindles constructed with the avowed idea to prevent the wabbling and gyration of the spindle and its load by giving to the same the capaeity to wabble, for in this spindle, no matter what the load may be, it is so firmly supported that it cannot yield to the force of any unbalanced load, but must run on its axial center.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A spindle-support consisting of the rigid bolster-case 12, having the long conical socket 11, the upwardly-extending tube 17, and the enlargement 13, forming the oil-reservoir, and the combined bolster and step-tube 9, having the conical pin 10 at its lower end, held in the socket 11 with a rigid lit, the upper end of the bolster fitting the bolster-case with a close sliding t, the bolster-case extending above the bolster-tube and provided with a groove or channel forming a passage for the return of the oil, the whole adapted to form a rigid support for the spindle, as described.

2. The combination, with the spindle-sup port consisting of the rigid bolster-case 12, provided with the long conical socket l1, the tube 17 extending upward above the bolstert-ube and having the oil-chamber 13, and the combined bolster and step-tube 9, rigidly secured in the conical socket by the pin 10 and closely fitting the upper part of the bolster, of the spindle 5, provided with the sleevewhirl 6, extending down over and surrounding the upward extension of the bolster-case, the whole adapted to support the spindle and hold the same against lateral or oscillating motion, as described.

HENRY F. WOODMANCY.
