`UNVrEDN STATES PATENT OFFICE. A
JOSEPH B. BANOROFT, OF HOPEDALE, MASSACHUSETTS.
SPINDLE i-'oR TwlsTER-FRMES.
SPECIFICATION forming part of Letters Patent No. 251,815, dated January 3, 1882.
, Application sind July 2o, 1ere.
To all whom t may concern:
Be it known that I, J ostern B. Bnivcaorr, ofHopedale, county of Worcester, and State of Massachusetts, have invented an Improvement in Spindles for Twister-Frames, of which the following is a specification.
This invention relates to improvements in spindles for twister-frames, and has special reference to a twister-spindle having at its top a permanently-attached sleeve provided with bobbin-driving pins, the sleeve being of such diameter as to receive between it and the spindle an extended bolster of the Sawyer class, and havinga sleeved whirl removably attached to the spindle below the bolster-rail, whereby the strain of the spindle-band is applied to the lower portion of the spindle or to its bearings, and so that byunscrewing or detaching the whirl the spindle may be removed from the frame.
In spindles for twister frames heretofore made sleeves secured to the spindles have been provided with whirls or wharves to receive the spindle-bands;4 but the application of the bands to the whirls at the lower ends ofthe sleeves, they acting as levers having their fulcra at the tops ot' the spindles, strains the spindles and draws the sleeves at their lower ends against the bolster-s. I lind that the spindle will run steadier and better by applying the whirl to the spindle between the bolster and foot-step rails, as usual; but in order to avail myself of xing the sleeve permanently upon the spindle, so thatit always remains at exactly the proper place with relation to the spindle top and bolster and balancedon the spindle, Ihavelnadethe whirl removable, which permits the spindle to be withdrawn from the bolster, bolster-rail, and frame without detaching the sleeve, as heretofore common. Where ame tallic sleeve is removed from the spindle each time the spindleis withdrawn it has been found very difficult and quite impracticable to replace the sleeve in the same position on the spindle, and consequently the spindle runs unevenly.
Figure 1 shows one of my improved twisterspindles witha bobbin attached, many of the accessories ofthe spindle being shown in section. Fig. 2 shows a modification.
The spindle a rests at its lower end in the step b of the step-rail c, and extends through the long or Sawyer bolster d, secured to theI bolster-rail c. Above the extended bolster, at the top of the spindle, is attached the sleeve f, having at its lower end a head or collar, g,pro vided with stop-pins h, which engage other stop-pins or equivalents in the recess at the lower end of the bobbin. This sleeve is chambered from its lower end to near its top, so as to receive within it the bolster, the said bolster lying between the spindle and sleeve, It is forced firmly upon the top ofthe spindle, and the outer portion of the sleeve is then turned true in a lathe, so that thereafter the sleeve which always remains up'on the spindle has its outer surface concentric with and runs true with the spindle.
` The whirl t', provided with a whirl-sleeve,j,
to extend upward to or into the bolster, and made to surround thetube 7c, projected upward from the step, is provided with a screw-thread to engage with a screw-threaded portion upon the spindle, as at l. By placing the whirl upon the spindle rather than upon the sleeve f, as heretofore common, the strain upon the spindle and sleeve is reduced, and by making the whirl detachable from the spindle the sleeve may be made permanent and the spindle unscrewed from the whirl can be drawn up through the whirl, the bolster, and the usual ring-rail. (Not shown) The foot-step is adjusted vertically by the tap-screw m, tit-ted to a screwthread in the'rail.A In Fig. 2 the whirl is at` tached to the spindle by a set-screw, a'. In such case the spindle need not he reduced in size within the whiil. t
I do notbroadly claim a sleeve carrying spindle combined with a spirally-grooved bolster intermediate of the said spindle and sleeve, the bolster having acup-like collar; nor do I broadly claim a spirally-grooved bolster having an oil-inlet and a `cup-like collar at its top provided with an oil-chamber and outlet, and combined with an internal spindle and external sleeve moved by it, as I am aware that such devices are shown and claimed in an application of Geo. Draper tiled June 24, 1875.
I claim- 1. The spindle and its permanently-altached metallic sleeve provided with bobbin-driving pins, combined with a bolster extended upward IOO between the seeve and spindle and a whirl re- In' testimony whereof have signed myname movably attached to the spindle between the to this speceation in the presence of two Subro step and bolster rails, substantially as describing witnesses.
