SPlNDLE-SUPPORT FOR CAP-SPINNING MACHINES.
SPECIFICATION farming art cf Letters Patent No. 443,659, dated December 30, 1890.
Application filed {Tune 27, 1890' Serial No. 356,926. (No model.)
To aZZ 2071,0171, it may concern.-
Be it known that I, GEORGE A. DRAPER, of Hopedale, county of Vorcester, State of Massachusetts, have invented an Improvement in Spindle-Supports for Cap-Spinning Machines,
of whichthe following description,in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.
In that class of spinning known as capspinning it is customary to use dead-spindles, or spindles which do not rotate, and caps are attached to them. On these spindles are mounted sleeves with whirls at their lower 1 5 ends. On these sleeves the bobbins for holding the yarn are placed.
In spinning, the sleeves with their bobbins are revolved rapidly about the spindle, it and the cap being without rotary motion. The
traverse for laying the yarn on the bobbin is commonly obtained in two ways, either by raising and lowering the vertical supports for the sleeves or by raising and lowering the supports of the spindles and caps. iVhen the sleeves and their bobbins are driven at high speeds, the spindles and caps jar, and this constitutes the limit of speed at which the machine can be run.
The object of this invention is to so cushion the dead-spindles that they shall not jar, and in this way the speed of the machine may be materially increased. It is customary to support the spindle rigidly at the lower end thereof.
5 Figure lot the drawings in vertical section shows part of a cap-spinning frame embodying my invention, and Fig. 2 a detail of the ste il he dead-spindle a, the rails b c, the cap (1 0 on the spindle, the tube e, having the whirl e, and the spool f are and may be all as usual. The lower end of the dead-spindle, instead of being fixed on the rail 0, as usual, is surrounded by an elastic or fibrous packing 5 g, contained, preferably, in a step-case h, the spindle being prevented from rotating in the said step-case by the restraining influence of a pin or projection 2, which enters a notch in the step.
I have shown the step-case as provided ex ternally with an inclined slot m, which is entered by a set-screw n, partial rotation of the said step case while the screw is slightly loosened enabling the spindle to be lifted more or less to bring the top of the spindle into the proper horizontal plane.
The bolster 0, on which the sleeve e rests in its rotation, is shown in Fig.1 as extended down in the railb, and as embracing the spindle in the rail, the bolster being surrounded 6c by a packing p. y
In a cap-frame having a dead-spindle held at its foot in a yielding bearing the sleeve a, carrying the spool or bobbin, may be rotated much more rapidly than when the dead-spindle is held rigidly, and at the same time, owing to the fact that the spindle is not jarret as much, the yarn produced is more uniform and of better quality.
I am aware that dead-spindles in a ringspinning frame have been placed loosely in rigid bearings and acted upon at one side between the said bearings by a leaf-spring, as in United States Patent No. 80,216, dated July 21,1868.
1. A deadspindle and a cap mounted thereon, combined with non-rigid support or supports surrounding the said spindle, substantially as described. s
2. A dead-spindle, a cap mounted thereon, and a support to hold the end of the spindle in a yielding manner, combined with a bolster surrounding the said spindle and with an elastic or yielding packing surrounding the said bolster, substantially as described.
3. A dead-spindle, a step-case havinga camgroove, an elastic or yielding packing, and a set-screw entering the said groove, to operate substantially as described. 00
. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
