THREAD-GUIDE FOR SPINNING-FRAIVI ES.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed January 2'7, 1905. Serial No. 242,903.

' specification.

The object of this invention is to produce a thread-guide so constructed that when it becomes necessary to piece up an end of the yarn on the bobbin as soon as the fingerboard is swung forward the yarn Which is being revolved by the bobbin is caught by the thread-guide and conducted to the eye, thus doing away with the slow process of inserting the thread in the eye by hand.

The nature of the invention is fully described below and illustrated in the accompanying drawings, in which- Figure 1 is a plan view illustrating my improved thread-guide (two being shown) in position in the edge of the finger-board. Fig. 2 is a sectional end elevation of the same. Fig. 3 is a front elevation. In Figs. 1 and 3 the thread or yarn is shown in dotted lines entering the slot in the thread-guide and in full lines in position in the eye.

Similar letters of reference indicate corresponding parts.

a represents an ordinary finger-board or guide.

My improved thread-guide comprises an integral plate of sheet metal or other suitablyprepared metal or material, one portion Z) of which is substantially horizontal and the other portion 0 of which is nearly vertical, being at a slightly-obtuse angle with the portion 6, said portion Z) constituting the tailpiece and being provided with a kink-catcher d, not new in this invention. Integral or rigid with the portion I) is a screw 6, by means of which the thread-guide is secured to the outer edge of the finger-board in the ordinary manner. The portion 6 of the plate is provided with a long horizontal arm f, extending from the opposite side from the tailpiece and nearly parallel with the front edge of the finger-board. The outer edge f of this arm is preferably slightly convex. A short arm g extends from the main portion of the plate (Z and curves slightly outward, as shown, its rear edge and the front edge of the shank portion of the arm f being of such a shape as to produce a narrow slot or passage 7, having a flaring mouth it. This passage leads at its inner end to a comparatively large hole a in the portion 6 of the plate, all as illustrated in Fig. 1.

In operation after the finger-board has been swung back, the bobbin placed on the spindle, and the finger-board swung forward the end of the yarn on the bobbin which is held in the hand is caught by the revolutions of the bobbin by the thread-guide and is guided by the arm f and the outer end of the arm g into the flaring mouth/r of the slot or passage 72 and thence into the eye 12. The end of the yarn which is on the bobbin may then be pieced to the end coming out of the rolls. By this means in piecing up an end the yarn is conducted into a thread-eye by the revolution of the bobbin instead of being inserted therein by hand, and much time thus saved. When the finger-board is thrown back to dot? the bobbin, the thread is doubled over and the doubled-over portion held against the outer edge of the arm g nearly opposite the eye 02 by means of the concave curvature of the outeredge of said arm and retained in said position until the board is lowered.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

The herein described improved threadguide for spinning-frames, comprising a horizontal plate 6 provided with a horizontal arm f adapted to extend substantially parallel with the outer edge of the finger-board; and the arm g extending from the portion bin the direction of the arm f and for a considerable distance along its outer edge, the outer edge of said arm g being slightly concave whereby its end or point projects slightly outward, and the inner adjacent edges of the arms 9 and f being respectively convex and concave whereby a passage of substantially even width for the most of its length is produced, the main portion being provided with the eye n connecting with the inner end of said passage, whereby the revolution of the bobbin automatically conducts the thread into the threadeye, and when the finger-board is thrown back to doff the bobbin the thread is doubled over and held against the slightly-concave edge of the arm g, substantially as described.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

CLARENCE A. PIERCE.
