Description
' UNHED STATES PATENT intron.
WILLIAM F. DRAPER, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TO GEORGE DRAPER & SONS, OF SAME PLACE.
SPINDLE-BEARING.
SPECIFICATION forming part of Letters Patent No. 505,196, dated September 19, 1893.
Application tiled May 29,1893. Serial No. 475,858. (No model.) Y
To all whom it may concern,.-
Beit known that I, WILLIAM F. DRAPER, of Hopedale, county of Worcester, Stat-e of Massachusetts, have invented an Improvement in 5 Spindle-Bearings, of which the following description,in connection with the accompanying drawings, is a speciiication, like letters on the drawings representing like parts.
In spinning the tendency of the band is to ro hold the bolster or lateral bearing against the interior of the supporting-case at one side and in the direction of the Vtension of the band, and as the bolster moves, due to the gyrations of the spindle, it must be against the band I5 pull, the elasticity of the band serving as a cushion in that direction.
Prior to my invention bolsters mounted looselyin supporting cases have been entirely surrounded by cushions made of textile and zo other materials, but I have found by experiment that by interposing a cushion between the bolster and case only in the direction of` when unequally loaded, but also reduces the.
cost of the cushions.
My invention consists essentially in the combination with a sleeve Whirl spindle and a supporting-case, of a lateral bearing for said spindle, said bearing being mounted loosely in the supporting-case, and acushion interposed between the said bearing and the said sup- 3 5 porting-case at but one section of the circumference of the said bearing, substantially as will be described.
Figure l in section shows part of a sleevewhirl spindle, and supporting-case and bear- 4o ing embodying my invention in one form; Fig. 2, a section in the line c. Fig. 3 shows a modification. Figlshows yet another modification, and Fig. 5, a modilied form of segmental cushion. 45 The rail A receives within it the shank B of a supporting case B.
The spindle C, having a'sleeve-whirl Of has its usual pintle entered into a bolster D, which, as represented, has a loose tit in the 5o supporting-case, the lower part of the bolster shown havinga notched collar D which is entered by a pin or projection D2 to restrain the rotation of the bolster with the spindle while the latter is rotated by the band B2. The lower end of the bolster in Fig. l, has, in practice, a coarse thread adapted to engage a coarse threaded projection ct, the upper end of which serves as a step for the foot ot the spindle, the portion arising from a block a', restrained from rotation in asuitable manner, 6o as by a pin or projection a2. This class of connection between the spindle and step is old and common, and provides not only for a limited amount of looseness for the bolster at its lower end, but also enables the bolster, it having, it is supposed, a tapered interior, to be adjusted to compensate for any wear, or to provide looseness between the tapering pintle of the spindle and the supportingcase.
The interior of the supporting-case in Fig. 7o I'is provided, see also Fig. 2, with a narrow y segmental packing or cushion d, it being applied only at that part of the supporting-caso against which the bolster would be drawn by Vthe pull of the band, the space between the bolster and supporting-case at other points, being open and free for the reception of oil, and to let the bolster move with no other restriction in the nature of a cushion than the oil and the band surrounding and rotating 8o the sleeve-whirl spindle. In Fig. 2 this free open space is marked d.
This invention is not limited to the exact shape or width of the cushion, so long as it is interposed where shown and described, leav- 8 5 ing other parts of the bolster unobstructed, and inasmuch as the cushion does not wholly, and only partially surrounds the bolster, I designate it as segmental.
This invention is not limited to any one 9o material for the cushion, or to the particular way shown ot support-ing it.
In Figs. l and 2 the supporting-case sustains the cushion, but in Fig. 3 the cushion marked d2 is contained between shoulders of 95 the bolster, and the bolster itself is shown as having an annular shoulder to rest on a shoulder of the supporting-case. l
In Fig. the cushion marked d3 is confined to the bolster by strings d4, and in Fig. 5 I roo have shown the cushion d6 as made ofa piece of thin steel or spring metal corrugated so as to act as a spring.
In Figs. l to 3, the cushion may be glued or cemented in place, or be confined in any usual or -suitable manner.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A sleeve-whirl spindle, a bolster or lateral bearing, and its surrounding supportingcase, combined with a segmental cushion interposed between the supporting-case and that side of the bolster or lateral bearing which is drawn toward the said case by the pull of the band, leaving other parts of the space between the said bearing and case free and unobstructed for oil and to let the bear-
