TUBING COMPANY, or HoN snALE, PENNSYLVANIA FLYER TWISTING FRAME Application filed August 15, 1928. Serial No. 299,837.

This invention relates to spinning and chiefly to the twisting mechanism of the type embodying a flyer twister frame, the purpose being to provide for the ready removal and replacement of the flyer, yet preventing casual displacement of the flyer from the spindle should it become loose.

The invention contemplates a. novel form of flyer includinga hub, or block formed with an annular groove, and a two armed flyer having its middle portion fitted in the annular groove of the hub and retained therein by means of two oppositely disposed pins.

While the drawing illustrates a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

vFor afull understanding of the invention and the merits thereof, referenceis to be had to the following description and the drawins; hereto attached, in which igure 1 is' a longitudinal, central, sec- V tional View of a bobbin and flyer twister embodying the invention showing the same mounted upon a spindle.

Figure 2 is an enlarged fragmentary, sectional view at a right angle to Figure 1 of the flyer and adjacent end of the bobbin.

Figure 3 is a detail sectional view on the line 33 of Figure 2 looking in the direction of the arrows.

Figure & is a detail sectional view onthe line 1-4L of Figure 2 looking in the direction indicated by the arrows.

' Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 denotes a spindle of a fiyer twisting frame and 2 designates the body of the bobbin which is adapted to slip upon the spindle 1 and engage the same frictionally so as to rotate therewith. A recess 3 is formed in the upper end of the bobbin 2 and receives the reduced portion 4 of a cap or head 5. Screws 6 or analogous fastenings secure the cap to the body of the bobbin 2. r The cap or head 5 is formed with a central opening in which isfitted a collar 7. A flange 8 projects inwardly fromthe outer end of the collar 7. The collar 7is pressed into. the opening 3 and retained therein by frictional engagement. Thetwister'comprises a hubor block 10 formed intermediate its ends with an outer enlargement'll and at its inner end with an eccentric flange 12 of a diameter to pass" snugly through the opening defined by the inner flange 90f the collar 7 The outer enlargement llis formed with an annular groove 13 in which isfitted a curved portion14= of the flyer." The hub or block 10 is formed with an opening to receive the spindle 1. vi W M' The'flyer includes two arms -l'5 wh'ich con stitute end portions of a wire, the middle portion of which is bent intosemi-circular form, as indicated at 14, to snugly; fit within the annular "groove13 and about the hub-of thetwisterg; .Pins "16 extend across the annular groove 13 and their ends are supported in the parts bordering upon the groove. The pins 16 are disposed in the angle formed be tween the arms and the semi-circular portion 14: of the flyer. The arrangement admits of ready replacement of a broken or crippled flyer as will be readily comprehended.

As shown most clearly in Figure 2 of the drawing the flyer is centered with reference to the bobbin by means of the spindle 1, hence ing opening enlarged at its outer end, a flange projecting inward from the bobbin across the enlarged portion of the spindle receiving opening, a flyer, and a flange projecting outwardly from the flyer and overlapping the flange of the bobbin to prevent outward displacement of the flyer, the parts being nor:

loo

mally held in operative position by means of the spindle.

2. In a flyer twisting frame, the combination with the bobbin, and flyer, of a flange projecting inwardly from the bobbin, and a companion flange rojectingoutWar-dly from the flyer, the two anges b'eingh'eld in given position by means of the spindle.

3. In a flyer twisting frame, the combination with the bobbin, a cap secured to the outer end of the bobbin and having a central opening, a collar secured within the opening of the cap and formed with an inwardly disposed fiange, and a flyer formed with an eccentric flange adapted to enter the said collar and overlap the flange thereof, the parts being held in operative position by means of the spindle. v

4:. .In a flyer twisting frame, the combine- -30 tion of a bobbin, a cap at the outer end thereof provided 'With ac'entral opening, a

collar within the opening of the cap and having an inner flange at its outer end, and a flyer'hav'ing an eccentric flange at its inner end normally disposed within the said collar and overlapping the inner flange, thereof to prevent accidental displacement of the fiyer which normally is held in given position means of the spindle.

5. n a flyer twisting frame, a bobbin, an annular flange thereon, a flyer, and aneccentric flange on the flyer to coact with the'flang'e of the bobbin and retained in cooperative position by the spindle when the bobbin and flyer are mounted thereon to prevent accidental displacement of theflyer.

In testimony whereof I aflix my signature.
