WILLIAM T. CARROLL, OF WORCESTER, ASSIGNOR TO GEORGE DRAPER 8a SONS, OF HOPEDALE, MASSACHUSETTS.
l SPINDLE.
SPECIFICATION forming part of Letters Patent No. 242,409, dated May 31, 1881. Application filed January 24, 1881. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM T. CARROLL, of Worcester, lllorcester county, State of Massachusetts, have invented an Improvement in Spindles, of which the following description, in connection with the accompanying drawings, is a specification.
My invention in spindles has for its object to enable the spindle and its y'arn load, under all circumstances, to find andy revolve about their true and' common center of gravity, to thus overcome the difficulties attendant upon or incident to vibration of the spindle by reason of an unequal distribution of Weight or balancing of the yarn load thereon, whereby the spin- 'dle is adapted Ato be run at a greater speed with less power and produce better yarn than 1s possible when the spindle runs in fixed or unyieldin g bearings and is unevenly loaded.A
Prior to this my invention' spindles have been constructed such as represented in United States Patents to J. S. Raworth, No. 226,789, April 20, 1880, and No. 227,129 to F. J .Rabbeth, to which reference may be had, wherein it was aimed to accomplish the advantages' herein desired to be attained by means of an elastic medium external to the bearings in which the spindle turns. In the Rabbeth construction referred to thelower end of thespindle, below its connection with the whirl, is eX- tended down into a loose bolster-bearing inserted in a tube connected with and extended upward from a iixed rail of the spinningframe, an elastic packing being interposed between the said bearing and tube.
In this my invention, instead of employing` a tube such as shown :in the said Rabbeth patent, down over and about which the whirlconneeted with the spindle is extended, and placing the bolster-bearing in the said tube, so as to receive in its open upper end the lower end of the spindle, I extend a bearing stud or pin upward from the center of a foot-piece sustained in a fixed rail of the machine, and above this stud or pin, which is long enough to extend above the plane in which the whirl connected with the spindle revolves, I have` placed a bolster-bearing, shown as an open-ended sleeve fitted over the said stud or pin. The
upper end of the said stud or pin, above the top of the said bolster-bearing, will preferably have a rawhide, bone, metal, or some other wcll-known orsuitable h ard washer interposed between it and the top of the chamber of the whirl. This bolster-bearing is provided externally with a suitable yielding or elastic covering or medium, such as felt, or yarn, or a woven or braided fabric, the said elastic medium operating as a cushion between the outer portion of the bolster-bearing and the interior of the whirl-sleeve, thus enabling the spindleto readily yield in all directions with more or less of a spring-action. The elastic cushion is herein shown located below the top of the stud or pin upon which the weight of the spindle and yarn load is sustained, and about which the Whirlsleeve of the spindle revolves, and the center of the whirl falls opposite the center of the bolster-bearing', so that the pull of the band driving the spindle will not tend to deflect the spindle from true vertical position, as it otherwise would do if diierently located with relation tothe said bearing.
Besides overcoming the gyration ofthe spindle resulting from an uneven balancing of the spindle and its yarn load, to securethebest results provision must be made to overcome the lateral strain on the spindle due to the pull of the yarn as it passes from the usual traveler to the bobbin during the rise and fall of the ring-rail-a strain which is especially noticeable in spindles as now constructed when the ringrail with its ring and traveler are at the upper part of their traverse.
The spindle, its supporting stud or pin, bolster-bearing, and elastic support herein described as of my invention have been devised with especial aim to overcome or reduce to the minimum the evil effects of the strain arising from the pull of the yarn when the rin g-rail is near the top of its traverse, and this I have accomplished by changing the leverage of the spindle, placing' the whirl below the support for the weight of the spindle, and locating the elast-ic support and bolster-bearing intermediate between the whirlsleeve and the said spindlc-support, the whirl being just opposite the center of the bolster-bearing.
By this construction and location of parts, as referred to, I am enabled to use a softer or less-dense elastic medium than has been found absolutely necessary in that class of spindles wherein the elastic lateral support is located above that bearing of the spindle which supports its weight, for in such spindles the elastic support, to be most e'ectual, must be equivalent almost to a solid surface. The less the density of the elastic lateral support the greater the ease with which the spindle may move to find its true center of gravity; and by changing the leverage of the spindle, as herein shown, I am enabled to use a very soft cushion between the sleeve-whirl and bolster, one so soft that it could not practically be employed in a spindle of the class referred to, where the increased lateral strain ot' the yarn on the bobbin and spindle near the top of the traverse acts with very much greater power than when the spindle is supported as shown in this my invention, and where the spindle proper heretofore extended into the whirl-sleeve is omitted.
The location of the yielding cushion or lateral support, to compensate for unequal loading of the spindle or bobbin inside the whirl in the line of the pull of the band driving the said whirl and below the point on which the spindle and its load rest and revolve, enables me to rotate the spindle with the greatest steadiness and with the minimum of wear aud of power.
Figure 1 represents, in side elevation and partial section, a spindle embodying my invention, it being supposed that the same is to be used in a rin g-spinnin g frame having a rising and fallin g rin g-rail and ring and traveler, such as made by the Sawyer Spindle Company, such frames being well known. Fig. 2 is a vertical sectional detail of the bolster-bearing and its elastic covering medium. Fi g. 3 is a detail of the interior of the foot-piece with the central fixed stud or pin broken oi'; and Fig. 4 is a modification to be referred to, the spindle and whirlsleeve being broken of above the whirl, the said figure being added only to show a modified, but usual, form of device for holdingthe spindle down in proper position.
The rail a will beV supposed to be the usual bolster-rail common to ring-spinning frames made by the Sawyer Spindle Company and its licensees. The foot-piece b, having a shank, b', to t ahole in the said rail, where it will be held in any suitable manner, has its upper portion chambered out, as shown at Figs. 1 and 3, to receive the lower end of the whirl-sleeve c and of the bolster-bearin g d, while at its eenter the said foot-piece b has a iixcd stud or pi n, c, extended upward, as shown in Fig. 1, to receive about it the said bolster-bearin g, and outside of it the whirl-sleeve, the said stud or pin extending upward above the line of pull of the usual driving-band on the whirl j', thus forming an extended, stili', stationary, unyielding center, about which, above and below the whirl f, the whirl-sleeve c revolves, carrying with it the spindle s, with which it is fixedly connected above the top of the said stud or pin c.
The bolster-bearin g d, herein shown as a sleeve open at both ends and as covered externally with an elastic cushion, g, ot' felt, woven or braided fabric, yarn, or other suitable yielding or spring material, or of metal wire, as in Fig. S of United States Patent No. 227,129, referred to, is placed about the said fixed pin or stud c, the latter extending through the top of the bolster, as in Fig. l.
Above the top of the stud or pin c, which top serves as the support for the wei ghtof the spindle, its attached parts, and yarn-load, I have herein shown a loose washer, h, of rawhide, but it maybe ot' steel, glass, or other vitreous or suitable material commonly used for hard bearin gs. The chambered whirl-sleeve c, connected at top directly with the lower end of the spindle s, and fitted over this bolsterbearin g and elastic cushion thereon, is made to rest on the said washer h if it be used, or on the upper end of the stud or pin c if the washer be omitted, and the lower end ot the said whirl-sleeve is entered loosely, as herein shown, within the chambered portion of the foot-rest b, it, however, ruiming freely therein. The length ofthe stud or pin e, and ot` the bolster-bearin g, will be substantially the same, and the whirl will be so placed on the whirlsleeve as to travel opposite the center of the stud or pin e and bolster-bearing, as shown in the drawings.
The lower end of the whirl-sleeve is shown as provided with a pin, k, to enter an annular groove, l, in the foot-piece b, to prevent the spindle rising from its seat or the top of the stud or pin or washer when a bobbin is being doifed from the spindle.
The portion of the foot-rest b above the annular groove I, is cut diagonally downward in the direction of the rotation ot' the spindle, as at m, to aiiord entrance for the pin k into the groove I, and yet prevent any accidental lifting of the spindle, as might happen if the cut m were vertical and it should be attempted to dof the bobbin at a time when the pin k and said vertical cut were in exact line vertically. Instead of this pin k and annular grooveV l, I may employ aturn-button or wire, j, (shown in Fig. 4,) itbeingadevicc shown in United States Patent No. 227,129 for the same purpose.
1 do not lay claim to any particular form of devices to hold the spindle down in proper position, nor do 1 desire to confine my invention to the employment of any especial means for lubricating the parts which run in contact.
I have shown in Fig. 1 an oil-hole, 2, made through the whirlsleeve,ii 1side the hollow upper part of the whirl, and oil fed therein will iow along the elastic or yielding cushion down into the chamber at the upper end of the footrest.
rllhe stud or pin e may be grooved sprally, as in Fig. 1, to form a channel for the upward IOO IOC
movement of oil from the chamber of the footrest, between the said stud e and the interiorV of the bolster-bearing, and out through the holes 3 to the elastic cushion g or the bolsterbearing may be grooved spirally, as at 5, Fig. 2, and be bored as at 6; or, it' desired, the bolster-bearing may have one or more vertical sawcuts through it, as shown in heavy black line 7, Fig. 2.
In the Rabbeth patent referred to the spindle extends below the whirl and the connection ofthe whirl-sleeve with it; but in this my improved construction the spindle terminates at its connection with the whirl-sleeve, and the stationary stud or pin e takes the place of the lower part of the spindle ot' the said Rabbeth structure, to opppose and sustain the pull ofthe driving-band on the whirl.
I claiml. The tiXed stud or pin and its surrounding bolster-bearing and elastic covering, combined with the spindle, its connected whirl and whirl-sleeve, the latter surrounding and being adapted to be revolved about the said stud or pin, with the bolster-bearing intermediate between them, substantially as described.
whirl-sleeve secured to the lower end of the spindle, and the whirl on the said sleeve, combined with a fixed stud or support on which the said spindle rests and revolves above the whirl, and abolster-bearing and elastic cushion interposed between the said whirl-sleeve and stud or spindle support, substantially as described.
3. The fixed stud or pin, its surrounding bolster-bearing and elastic covering, and the spindle, and connected whirl-sleeve extended down about the said bolster-bearing and stud or pin, combined with the loose washer intermediate between the upper end of the said stud or pin andthe top of the chalnbered whirlsleeve, substantially as described.
In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
WILLIAM T. CARROLL.
