8 Claims.

This invention relates to certain new and useful improvements in the flyers employed in connection with spinning machines.

One of its objects is to provide a fiyer of this character having a freely gyrating bearing and having eiiective means for cushioning the shocks incident to sudden changes in thread-tension.

Another object of the invention is the provision of a simple, inexpensive and efficient fiyer having self-contained means for permitting a cushioned axial as well as lateral movement of the flyerbearing relative to its spindle-attaching sleeve in response to any pull exerted by the thread in unwinding from the take-oil bobbin, thereby rendering the fiyer flexible and adapting itself to the work required of it.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a side elevation of a bobbin and spindle showing my improved fiyer associated therewith. Figure 2 is an enlarged top plan view thereof. Figure 3 is an enlarged cross section taken substantially in the plane of line 33, Figure 2. Figure 4 is a fragmentary cross sectional view of the bearing member of the flyer. Figure 5 is a horizontal section taken on line 5--5, Figure 3.

0 Similar characters of reference indicate corresponding parts throughout the several views.

This invention is applicable to spinning machines of well known construction, l0 indicating the bobbin-spindle and II the take-off bobbin 35 mounted thereon. The thread or yarn from the bobbin extends upwardly through the eyes of the usual fiyer wires l2 and I3 mounted on a holder or wire base l4, and thence guided upwardly through a guide or centering eye I5 to a take-up spool (not shown).

The flyer body, to which the wire-base I4 is attached, is preferably in the form of a self-contained unit consisting of an anchoring sleeve or journal 16 adapted for frictional engagement with 45 the tapered end of the spindle ID, a bearing member I'l loosely fitted on the sleeve to revolve thereon, and a loosely-disposed or floating washer or cushioning element l8 arranged between the sleeve and the bearing member. Intermediate its upper 50 and lower ends the journal-sleeve has an annular flange or thrust shoulder I9, which, in conjunction with the cushioning element l8, serves to support and limit the axial displacement of the bearing member I! on the sleeve.

The bearing member is preferably made from a non-metallic material, such as a fiber composition or the like, which eliminates the necessity of using oil or grease to lubricate it, and whose lower portion has an opening 20 freely encircling the corresponding portion of the sleeve below its flange 5 i9. At its lower end the bearing member is reduced in diameter to provide an attaching neck 2i to which the wire-base I4 is fitted, the lower edge of such neck being upset or rolled over the adjoining bottom side of the base, as indicated at 10 22 in Figure 3, to securely anchor said base to the bearing member. The upper portion of the hearing member I? is hollowed out or counter-bored to provide an annular space, socket or compartment 23 about the companion flanged portion of 15 the sleeve I6 and is of a depth to permit of a limited axial displacement of the bearing member relative to the sleeve. Loosely fitted in the compartment 23 and encircling the sleeve, with its bottom side resting on the sleeve-flange l 9, is 20 the freely-floating washer or cushioning element l8 which is preferably made of a fiber composition similar to that of the bearing member IT. The upper marginal end of the latter is curled or bent over to form an annular retaining flange or 2 shoulder 2d which overhangs the washer and constitutes the means by which the bearing member is held in suspension from the sleeve I6. By this construction, the bearing member is free to gyrate about the attaching sleeve and to move axially or vertically of the spindle, being limited in its upward movement by the bottom of the bearingcompartment 23 abutting against the sleevefiange I9 and in its downward movement by the bearing-flange 24 abutting against the washer or cushioning element 18. The washer, being free of the sleeve and the bearing member, is permitted to move independently thereof to adapt itself to any axial or lateral movement of the bearing member in response to the pull exerted on the thread during the spinning operation. Furthermore, if the friction between the washer and the sleeve-flange i9 is greater than that between the washer-periphery and. the bearing member,

the washer will turn with the spindle without affecting the flyer-speed. On the other hand, if the reverse of these conditions takes place, then the washer-speed is increased to the flyer-speed.

In the twisting of fine threads at high spindlespeed, controlled low tension is necessary. My 5 improved flyer construction embodying the floating washer or cushioning element I8 automatically effects this control by cushioning the shock of sudden tension due to the thread holding to the take-off bobbin II and particularly the sudden shocks incident to the vertical movement of the fiyer-body on the journal-sleeve IS. The threads, in paying off from the bobbin, follow the turns on the bobbin and rake over them and sometimes the take-oflf end lodges or lays between adjoining thread-turns on the bobbin, resulting in .a sudden tightening or pull on the thread between the bobbin and the fiyer. The thread thus caught is suddenly released, at which turn the floating washer l8 imparts a cushioning effect to the displaced fiyer to absorb the shocks created by the sudden release of the caught thread.

I claim as my invention:

1. A fiyer for spinning machines and the like, comprising a journal-sleeve adapted for attachment to a bobbin-spindle and having a thrust shoulder thereon intermediate its ends, a bearing member mounted on the sleeve and having a socket therein about said thrust shoulder, and a freely-floating element disposed within said socket about the sleeve and engageable with said shoulder.

2. A fiyer for spinning machines and the like, comprising a journal-sleeve adapted for attachment to a bobbin-spindle and having a thrust shoulder thereon intermediate its ends, and a bearing member mounted on the sleeve and including an independent, relatively movable element engageable with said shoulder.

3. A fiyer for spinning machines and the like, comprising a journal-sleeve adapted for attachment to a bobbin-spindle and having a thrust shoulder thereon intermediate its ends, a bearing member mounted on the sleeve and having a socket therein about said thrust shoulder whereby a limited axial movement of the bearing member relative to the sleeve is permitted, and a cushioning element freely fitted in said socket about the sleeve between said thrust shoulder and the opposing end of said bearing member.

4. A fiyer for spinning machines and the like, comprising a journal-sleeve adapted for attachment to a bobbin-spindle and having a thrust shoulder thereon intermediate its ends, an axially displaceable bearing member mounted on the sleeve and having a socket therein about said thrust shouldenthe bottom of said socket being adapted to abut said shoulder to limit and cushion the upward displacement of the bearing member on the sleeve, and freely-floating means in the upper portion of said socket above the sleeveshoulder for limiting and cushioning the downward displacement of the bearing member on the sleeve.

5. A fiyer for spinning machines and the like, comprising a journal-sleeve adapted for attachment to a bobbin-spindle and having a thrust shoulder thereon intermediate its ends, an axially displaceable bearing member mounted on the sleeve and having .a socket therein about said thrust shoulder, the bottom of said socket being adapted to abut said shoulder to limit and cushion the upward displacement of the bearing member on the sleeve, and a washer loosely fitted in said socket and about said sleeve above the thrust shoulder thereof for limiting the downward displacement of the bearing member on the sleeve.

' 6. A fiyer for spinning machines and the like,
