IMPROVEMENT IN SPINDLES FOR SPINNING.

Specification forming part of Letters Patent No. 35,145, dated May 6, 1862,

To all whom it may concern.-

Be it known that I, JAMES EATON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Spindles for Spinning, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this speciication, in which- Figure 1 is one of my improved spindles with a partially-formed cop thereon; Figs. 2, 3, and 4, details to be referred to.

In spinning with the ordinary spindle, with its blunt or rounded end over which the thread slips as the twist is being put in, the thread is subjected to a series of vibrations caused bythe slipping at short intervals of the thread over or oft from the end of the spindle. These vibrations not only interfere with the regular drawing ol the thread from the roving and cause the thread to draw harder at one instant than at another, and render it more liable to break, but the twist is not put in by a continuous regular operation, but by an intermittent one, whereby the thread is not spun so smooth and uniform as is desirable. Another objection to these vibrations is that the many small fibers which may be observed standing out from the surtace of the thread, and which should be twisted in with it, are thrown off and wasted, iilling the room with dust. To obviate these vibrations is the object of my present invention, which consists in so forming the point of the spindle that the thread will draw from the axis of the spindle.

That others skilled in the art may understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A, Figs. l and 2, is the spindle, the top end of which is so formed that when it is revolved in the direction of the arrow, Fig. 2, and the thread a is drawn in the usual direction when. spinning, which is nearly horizontal, as shown in the drawings, the thread will be carried in by the grooves and inclines into the central opening, c, while when the thread is drawn up vertically after being thrown or drawn out from the opening c (as when the pieceris drawing it ott) it will render oit freely from the outer surface of the spindle without the necessity of stopping the spindle. There are various forms which may be given to the point of the spindle to accomplish these ends-without departing from the spirit 'of my invention.

I have shown in Figs. l and 2 the end of the spindle formed in a scroll, the part 5 ofwhich projects so as throw the thread, when held vertically, off from the center, and as the spindle is revolving rapidly in the direction ofthe arrow the thread will pass from the portion 5 to the portion 6 without falling into the opening or slit between the point 7 and the shoulder S; but when the thread a is inclined, as shown in red, it will fall 011 the incline 9 and draw up under the point 7 into the central opening, c. In Fig. 3 the same end is accomplished by reducing the size of the scroll, leaving a shoulder, h, immediately beneath it, which, when the thread is held up vertically, keeps it out beyond the inclines l0 and ll and prevents it from running into the scroll; but when the thread is lowered, as in Fig. 2, it is at once carried into the scroll and drawn from the axis ot the spindle. It is quite desirable that this provision be made for drawing off the thread vertically, as otherwise thepieeer would have to stop the spindle when he4 wished to tie a broken thread. The form shown in. Fig. it will not accomplish this, as the thread falls onto the incline 12 and is led into the scroll.

Among other advantages of this improved center-draft spindle I may mention that it requires less power to operate, as the thread, being kept at an equal tension by drawing all the time from one point on the spindle,

set forth.
