SPECIFICATION forming part of Letters Patent No. 747,134, dated December 15, 1903.

Application filed December 15, 1902. Serial No. 135,21 (No model.)

T 0; whom it may concern.-

Be it known that I, MALCOLM CAMPBELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Fliers, of which the following is a specification.

This invention has relation to fliers, having forits object to provide certain improvements therein whereby the efficiency of the flier may be enhanced, the ease and rapidity with which the yarn may be operatively threaded thereinto increased, and the construction of the flier simplified. I

On the accompanying drawings,which illusirate embodiments of the invention, to which, however, said invention is not limited, Figure 1 represents a perspective view of one form of flier. Fig. 2 represents a side elevation of the same. Fig. 3 represents an elevation on the other side with the counterbalancing-arm broken off at the dotted line in Fig. 1 and looking in the direction of the arrow. Fig. 4

represents a section on the line 4: 4 of Fig. 3.

Figs. 5 and 6 represent another form of flier embodying the invention.

It is to be understood at the outset that the phraseology herein employed is for the purpose of description and not of limitation.

On the drawings, 10 11 respectively indicate the arms of the flier, which are mounted to rotate in the usual manner. The arm 11 carries the yarn, and the arm 10 is employed to counterbalance the weight of the arm 11 and its operative parts. The said arm 11 is substantially fiat and substantially tangential to its circle of movement. The edges of the arm are provided with ribs or beads 12 13, respectively, which form a groove or a longit-udinally-extended guide 14 for the thread. An eye 15 is formed in the upper portion of the arm for the yarn to pass through said arm and extend down the elongated guide 14. The curved portion of ihe arm 11 is provided with a curved groove 16 for the reception of the yarn after it leaves the guide 17, through which the yarn is initially passed. Pivoted to the arm 11 there is a presser-finger 18, having in its fiat end an eye 19, through which the thread may be passed to the bobbin or cop. The said finger is formed with or has connected to it an upright tension-bar 20, arranged in parallelismwith the arm 11 in front of the rib 12 thereof. The said bar is practically coextensive in length with the straight portion of the arm 11. Its upper end is formed with a hinged member 21, extending through a slot 22 in the arm 11. The finger 18 is formed with an aperture 23, through which the reduced end of the arm 11 passes, the construction being such that the finger 18 is adapted to swing about an axis coincident with the median line of the lower end 24 of the said arm.

To permit the passage of the yarn from the elongated groove 14 to the presser-finger, the arm 11 is formed at its lower end with an eye 25, one wall of the eye terminatingin a downwardly-projecting pin 26, whereby the eye is formed with an open throat to permit the yarn to be passed thereinto with ease and rapidity. Thepin 26 also acts as a tension device over which the yarn must pass before it is wound around the presser-finger and passed through the guide 19 therein.

In operation the function of the tensionbar 20 is to hold the flat end of the presserfinger against the yard which is built upon the bobbin or cop, the centrifugal action being suflicient to throw the said bar 20 outward,and thereby force the end of the presserfinger inward toward the center of rotation of the flier.

In threading the flier the yarn is passed through the eye 17, around the tubular top of the flier, and is laid in the groove 16. It is then passed through the eye 15 into the elon-. gated guide or groove 14 on the inner side of the arm 11. Thence it passes outward through the eye 25, around the pin 26, and may be wrapped one or more times around the finger l8 and passed through the eye or guide 19.

It is evident that the eye or guide may be formed on the finger 18, as indicated in Fig. 5. In this case it will be observed that the yarn extends under the end of the arm 11 into a guide or eye 27, formed on the hublike portion of the finger 18, whence it passes to the eye 19.

The advantages due to the construction as thus described will be apparent. The arm 11 is fiat instead of tubular, whereby there is no chance for the accumulation of dust and lint to cause the breakage of the yarn. This is an important feature in the construction, inasmuch as the elongated guide on the inner face of the arm 11 is open and exposed, so as to be readily cleaned. The yarn is maintained in the said guide by centrifugal action during the rotation of the flier. Again, it will be observed that the tension-bar 20 is elongated, so thatit is supported from the upper'end of the arm, and consequently inasmuch as the weight is not carried by the lower end of the arm there is not the same tendency for the lower end of .the arms to swing outward by centrifugal action as would be the case were this construction not followed.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attemptingto set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- 1. A flier having a thread-carrying arm, a

vpresser-finger, and a tension-bar connected to said finger, said arm having an open groove extending longitudinally on its inner face for the reception and lateral retention of the yarn, and having means for guiding the yarn from said groove to said finger without passing it around said tension-bar.

2. A flier having an arm provided with a longitudinal open guide or groove on its inner face, an eye at the upper end of said groove, and an eye or guide at the lower end of said groove, and a presser-finger pivoted on said arm to which the yarn is conducted directly from said last-mentioned eye or guide.

3. A flier. having a substantially flat arm formed with an open groove on its inner face, and an eye at the upper end of said groove, a press'er-finger, and a guide for conducting the yarn to said presser finger from said groove. 47. A flier comprising an arm having parallel ribs or flanges on its' inner face forming an open elongated yarn-guide, an eye at the upper end of said guide, an exterior yarn guide or groove on the curved part of said arm, and an eye at the lower end of said elongated yarn-guide.

5. Aflier havinganon-tubular thread-carrying arm, a presser-finger pivoted at the lower endof said arm, a tension-bar connected to said finger, the said arm having an opening in the upper end thereof for the passage of the yarn therethrough, and means for conducting the yarn from the lower end of said arm directly to the said presser-finger without passing it around the tension-bar.

6. A flier having a substantially flat nontubular arm, a presser-finger pivoted on the lower end of said arm, and a tension-bar connected to said finger,said arm having an aperture near its upper end for the passage of yarn therethrough from its outer to its inner face, and also having an eye at its lower end for conducting the said yarn directly from the arm to the presser-finger without passing it around the tension-bar.

'7. A flier comprising an arm, a presser-finger pivoted upon the lower end of said arm, atension-bar connected to said finger, means for cond noting the yarn from the outer face of the said arm at the top thereof to the inner face of said arm, and means for conducting the yarn from the inner face directly to the presser-finger without passing it around the said tension-bar.

8. Aflier havinga non-tubularthread-carrying arm, with an inner face and an outer face, a presser-finger pivoted at the lower end of said arm, a tension-bar connected to said finger, said arm having an opening at its upper end for the passage of yarn therethrough, and a guide for conducting yarn along the inner face of said arm from the said opening to the lower end thereof, and thence directly to said presser-fiuger without the interposition of said tension-bar. I

9. A flier having a non-tubular thread-carryingarm,apresser-finger pivoted at the lower end of said arm, a tension-bar hinged at its upper end tosaid arm and su pporting said finger, and means for conducting yarn to and along the inner face of said arm and thence directly to said finger without the interposition of said-tension-bar.
