WILLIAM T. CARROLL, OF WORCESTER, ASSIGNOR TO GEORGE DRAPER 85 SONS, OF HOPEDALE, MASSACHUSETTS.
SUPPORT FOR SPlNNlNG-SPHNDLES.
SPECIFICATION forming part of Letters Patent No. 391,737, dated October 23, 1888.
Application filed Juno 15, 1887. Serial No. 241,347. (No model.)
To @ZZ wir/m it may concern:
Beit known that I, WILLIAM T. CARROLL, of Worcester, county of W'orcester, and State of Massachusetts, have invented an Improvement in Supports vfor Spinning-Spindles, of which the following` description, in connection with the accompanying drawings, is a speciiieation, like letters on the drawings representing like parts.
My invention relates to that class of bearing especially adapted to enable the spindle to become self-centering to its load.
In accordance with my invention the bolsterin which the pintle ofthe spindle revolves, i5 and which constitutes the lateral bearing for the spindle, hasa shoulder which takes bearing upon a tapering seat formed within a surrounding bolster-support, the diameter of the opening at thelower end of the tapering seat 2o being larger than the external diameter of the bolster extended through it, so that the bolster has freedom of motion in the bolster-support to enable the spindle to adaptitself to an unbalanced load; but the rotation of the bolster with thespindleis restrained by a suitable pin or projection, or in other usual manner. ProA viding the bolster-support with a tapering rather than with a concaved seat, as common in what is called a ball-and-socket joint, 3o and the bolster with a shoulder having, preferably, a substantially right-angled corner to bear on the tapering surface of the seat, the gravity1 of the spindle and bolster acts to help center the spindle with relation tothe bolstersupport.
Figure l of the drawings in elevation and section shows a spindle and bearing embodying my invention; and Fig. 2 is a modilication, to be described.
The spindle A, having a sleeve-whirl is of usual construction.
The bolster-support B (shown in Fig. 1 as a rail) is bored to form a tapering seat, b, and a chamber, b, below it, in which is entered loosely the foot d of the bolster D,the said bolster having, preferably, a rightangled shoulder, c, which bears upon the said tapering seat, the gravity of the bolster, due to its weight and the weight or' the spindle within 5o it, acting to keep the bolster down closely upon the seat, the smal-l or sharp corner e, in contact with the tapering surface, forming a uniform bearing with the minimum of friction. The foot of the bolster, as well as that part of' the said bolster above the shoulder e, 55 is free to move laterally or to tip without other restraint than that due to gravity, as the lower end of the spindle moves under an unbalanced yarn load. The pin or projection g, held in the rail, (see Fig. 1,) enters ahole in 6o the bolster and restrains the rot-ation of the bolster with the spindle; also prevents the bolster from being elevated with the spindle.
In Fig'. 2 I have shown the bolster-support as made in a separate piece set into an ordidary rail and retained in place by a nut, c', screwed upon its shank.
I do not claim a bolster having a shoulder convexed at its under side to rest in a concaved seat, the said shoulder being iixed in 7o the said seat by means of a washer screwed upon the bolster in such manner as to prevent rocking or lateral motion of the bolster with the spindle under varying loads.
I claiml. The spindle, the bolster-support provided vwith the tapering seat and below the said seat with a chamber, combined With a bolster having a shoulder, c, the edge of which rests on the said seat and is free to rock or tip 8c thereon with the spindle, substantially as described.
2. A bolster-support having a tapering seat and a chamber below the said seat, combined with a bolster having a shoulder resting on the said seat, the foot of the bolster entering loosely the chamber of thebolster-support below the said seat, substantially as described.
3. The bolster-support having a tapering seat and a chamber below the said seat, combined with a bolster having a shoulder resting on the said seat, the toot of the bolster entering loosely the chamber of the bolster-support below the said seat, and with means to prevent the rotation of the bolster in the bolster-support, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
VILLIAM T. CARROLL.
