YARN-SEPARATOR FUR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 256,174, dated April 11, 1882.

Application filed November 2811881. (N model.)

To all whom it may concern:

Be it' known that we, CHARLES E. THOMAS and JOHN F. WORK-ALL, of \Voonsocket, connty of Providence, State of Rhode Island, have invented an Improvement ill Yarn-Separators for Spinning-Machines, of which the following description, ill connection with the accompanying drawings, is a specification.

Our invention relates to spinning-machines; and it consists essentially in operating the separators independently of the ring-rail.

As heretofore constructed the separators have been mounted upon a rock-shaft located near the ring-rail, and the separators, by a suitable stop, have been held in horizontal position between the spindles when the ring-rail was in its lowest position; but when the ringrail was lifted it acted upon and lifted the separators and turned the said rock-shaft.

The strain on the ringrail when liftingaseries' of separators increases the wear of the guides for the ring rail, and ultimately renders its movements untrue. To obviate this wear of the guides we have devised mechanism independent of the ring-rail to automatically operate the rock-shaft carrying the separators,the mechanism herein shown for such purpose being partially the same as that employed to lift the ring-rail, so that the said separators are operated simultaneously with the ringrail, but

are not actuated directly by it, as heretofore.

The said independentmechanism isalso so constructed that the separators may be lifted by the operator independently of the movement of the rail and its lifting mechanism.

Figure 1 represents in front elevation, a sufficient portion ofa ring-spinning frame to illustrate our invention, the ring-rail being shown for lifting the ring-rail, and will be operated by the heart or other usual cam.-

The separators b are extended centrally between the adjacent spindles s, and are adjustably attached by suitable screws to the paral- 5 lel rods 0 0, having their end pieces, d, pivoted, as at 0, (see Fig. 1,) so as to turn ill the depending brackets c.

At one end the pivoted separator-carrying rods 0 c, forming a sort ofshaft, are provided with an adjustable counter-weight,f, of sufficient size to nearlycounterbalancetheweight of the series of separators.

At the rear side of the rods 0 c, 0r shaft which holds the separators, we have attached an arm, g, having preferably a curved face, as shown ill Fig. 3. This arm 9 has apin, g, with which is connected one end of a suitable chain or cord, h, the other end of which is joined with a flanged huh, I, secured to a sleeve, L having a finger, 3. The sleeve Z is placed loosely upon the shaft a but the finger 3 is made to rest against the finger 4 on the hub 5, which is adjnstably secured to the said shafta". The weight of the separators is suf- 7 ficient when they are horizontal, or until they nearly reach a vertical position, to keep the finger 3 pressed against the finger 4., and as the shaft a is rocked to raise and lower the ring-rail the finger 4 of the collar, acting against the finger 3 of the sleeve 1", turns the huh I, and so draws upon the chain or connection 71. as to turn the rods 0 c or shaft holding the separators, raising them gradually in advance ot' the rising ring-rail and permitting them to follow down closely after the descending ring-rail, as will be understood.

Ifit is desired to lift the separators while the ring-railisatrest,the sleeve may beturned v on the shaft o independently until the separators are brought into vertical position, as shown ill dotted lines, Figs. 1 and 2, whenthe weightf will maintain them ill such position until again turned down for operation.

We claim- A 1. The series of spindles, the separators 1/, extended centrally between adjacent spindles, the rocker-shaft with which the separators are attached, hearings to hold the rocker-shaft, and the connection h, combined with the hub :00
