IMPROVEMENT m SPlND LE-BE ARlNG S FOR SPlNNlNG-MACl-IINES.

' Specification forming part of Letters Patent No. 122,705, dated January 16, 1872; Reissue No. 7,814, dated July 24, 1877; application filed February 10, 1817.

To all whom it may concern Be it known that I, Lrmmns Gnnnrr'nm, of Lewiston, in the county of Androscoggin and State of Maine, have invented certain new and useful Improvements in Machinery for 'an auxiliary cap to protect the interior of the bobbin from access of oil; and Fig. 9, a sectional elevation of part of a spinning-frame, embracing in one view the various contrivances to be hereinafter more particularly described.

This invention is applicable to that class of spinning-machines amon g which those'known as ring-spinning machines" are the most important, an'IT'which are characterized by the following peculiarities of construction, viz

First, the spindle is mounted on a stationary step, so as to have only a motion of rotation, and may therefore be termed a stationary live-spindle. v

Second, 'the bolster and its supporting-rail are fixed in position so that the length of that portion of the spindle which projects above its upper bearing remains constant.

Third, the spindle and bolster may be,-and in practice usually are, so proportioned and arranged as to permit the bobbin to be brought dowir-within a distance froin' the top of the" bolster-rail much less than the length of the bobbin surface to be covered by the yarnload.

The object of the principal improvements embraced in this invention is to enable the spindle to run at greater speed with less vibration of its bobbin and the yarn wolii. thereon than heretofore, an minim reduee the power required to drive it. These out the lower end of the bobbin wilfle' ing it in the same relative posititin and by'extending the bolster upward, so as to bring the upper bearing forthe spindle nearer to the top of the load carried by it than would otherwise have been possible.

The other improvements have for their object the proper lubrication of the spindle and its bearings, and the protection of the bobbin from access of oil.

In the drawing, A represents the spindle, provided with a helical groove, a, extending around it. The whirl shown at B projects from a tube or sleeve, (3, which is fitted by a socket, b, to the part c of the spindle, and is attached thereto by means of a slot, d, and stud e. The upper bearing or bolster d is shown extended upward 'into a ohamber,f, within the bobbin, and above this chamber the bobbin is bored out lengthwise to receive and fit closely to and upon that part g of the spindle which extends above the bolster, or to certain portions of such part g, so that when the spindle is rotated it causes the bobbin to turn with it and to revolve around the stationary bolster.

.The bolster is socketed intoa supporting rail, and is confined thereto by a clamp-screw acting against the'tenon it. There should be room between the bottom of this rail andthe top of the whirl-sleeye to enable the latter to be raised snfliciently for oil to bespoured into the step i, by which the foot lflof the spindle is supported. This step is shown mounted upon the top of a standard, E, which is supported by a rail below.

The bolster is formed with channels or grooves -l, extendingjlgmgthwise in its outer surface from the top of it down to thebase part 1, which is providedjwith an annular v (diiih'iiel or groove, it, and a passage, 0, leading therefrom to the bore of the bolster.

There is also another oil-passage, p, extending into the sleeve of the whirl. Encompassing the bolster and its base is a tubular guard, F, provided its lower part with an annular trough, Q, on of which a hole, 1', leads to and over the chapnel a. Qn pouring oil into the .tmugh q itwiil flow therefrom through the hole 1 into the channel a, and thence through i outlet 0 iirie the bore of the bolster, and

the the spindle is rer the bolster, will ibis: down in the thereto by the frictional faces brought in contact.

I am aware that it is not new in some forms toting the oil will be elevated ii: by the helical groove, and, passing: up n .r i .e top oi grooves upon its outside, within the guard F, and thence into the channel cngain. 'lheoil will also find itswaydontn. thronghthe whirl-cinema into the step of the spindledbot. in order, however, that the oil which circulates up through anddown outside the"bolster may not getupon the inner surface of the bobbin, an auxiliary tubular cap or sleeve, G, is placed on and over theguard F and the bolster D. I

This construction renders it necessary. to

make the chamber of the bobbin of suiiicientv size to receive not only the extended bolster, but also its adjuncts, such its the guard and cap described, to enable the bobbin to revolve without contact or friction therewith or interruption therefrom. to the spindle by close contact therewith" lit The bobbin is held on or one or more pl above the. top of the bol- In coeseqnznce of locating the bolster or upper bearing for the spindle within the bobbin, and thereby reducing the length of the unsupported portion of the spindle, it is i made possible to dispense with much of that part of tbespindle which usually extends be low the whirl, and also to materially reduce the diameter of the spindle throughout its en tire length, whereby its Weight and the power required to drive it are considerably lessened, while its capacity is materially increased.

It will be seen, 01] reference to thedrawin'g,

that the bobbin therein delineated is what istermed a quiltbobbin, that its bore above the chamber in it conforms to atalpor upon that portion of the spindle which extends above the bolster, and that when the bobbin is applied to the spindle, it ettaches itself adhesion of the surof flier-frames to surround the spindle with a. long tube, fitting to it closely and extending within the bobbin. But in all such cases either the spindle and bobbin have been driven at varying speeds, d have hnda varying vertical position wit relation to each other, or the outside of the long tube has been made to serve as a bearing for n flier, thereby coin sunning a great amount of power, limiting the by the yarn-load.
