Patented Sept. 24, 1935 FLIER FOR SPINNING MACHINES Henry C. Herr and Harvey E. Herr, Buffalo, N. Y., assignors to Herr Manufacturing Company, Inc., Buffalo, N. Y., a corporation of New York Application April 27, 1934, Serial No. 722,662

13 Claims.

This invention relates to improvements in the fliers employed in connection with spinning machines.

One of its objects is to provide a flier ofthis character which is so designed and constructed as to produce an even, constant and minimum thread tension during the spinning operation, all of, which attributes are particularly essential to the spinning of synthetic threads and yarns.

Another object of the invention is the provision of a balanced flier having means for developing or creating, during the high speed motion of the flier, a force for counter-acting the centrifugal force developed by the flier wires.

A further object is the provision of a flier for spinning machines which is simple and inexpensive in construction, and which is efficient in operation and assures a minimum uniform tension on the threads at all times.

In the accompanying drawing:-

Figure 1 is a side elevation of a bobbin and spindle showing the improved flier operatively associated therewith. Figure 2 is an enlarged top plan view thereof. Figure 3 is a cross section taken in the plane of line 3-3, Figure 2. Figure 4 is a bottom plan view showing the invention in connection with an eccentric type of flier. Figure 5 is a cross section showing this type of flier in position on the bobbin.

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

Referring to Figures 1-3 of the drawing, I0 indicates a spindle of the usual tapered form and II a bobbin mounted thereon. The flier-body,

which is detachably mounted on the bobbinspindle, may be of any suitable construction, that shown in the drawing consisting of an anchoring sleeve or journal 12 for attachment to the tapered end of the spindle, a hub l3 rotatably mounted on the journal and flier wires I4 suitably carried thereby and projecting from one side thereof. By way of example, we have shown these wires connected to a member l5 projecting from one side of the hub and. retained in loops l6 formed therein, a clamping ring or segment I! being employed for securely holding the Wires against displacement relative to the retaining loops. In the drawing, two flier wires are depicted, one having a depending threadengaging eye at its outer end which during the rotation of the flier assumes the outwardly-deflected position seen by full lines in Figure 1.

Projecting from that side of the flier hub I3 diametrically opposite to that of the flier wire supporting member I5, is a member l8 which is designed to provide a means for counter-balancing the weight of the flier wires and their attaching means when the flier is at rest, and which is further so designed as to develope or generate a force to counteract the centrifugal force de- 5 veloped by the flier Wires when the flier is in motion. To this end, the member 18 is provided with a weight-forming element l9 which acts to counter-balance the wire-bearing side of the flier and which is so shaped as to provide an air 10 deflector which functions to produce an outwardly-acting force during the variable high speed operation of'the flier to correspondingly compensate or counteract the centrifugal force developed by the flier wires. In its preferred 16 form, this element 19 is in the form of a flange projecting from the outer edge of the member l8 and is substantially V-shaped in plan, the apex thereof facing toward the hub-axis to thereby provide a convex inner surface against which 20 the air is impinged during the high speed operation of the flier and a concave outer surface where a vacuum is created to thereby exert a pulling force or effect on that side of the flier which counteracts the centrifugal force of the flier 25 wires with the result that the flier revolves evenly and uniformly about the spindle to maintain an even tension on the threads at variable speeds. To prevent any tendency of the flier to tilt, as in response to a downward pull on the flier 30 when the thread is being taken off the bobbin, we preferably provide the flier-member l8 with air-impinging or deflecting surfaces or depressions 20 which are located in the top side of and adjacent the marginal side edges of said member 35 and against which the air is deflected to maintain the flier in a level position at all times, the air acting on these surfaces in a cushioning or shock-absorbing manner to resist tilting of the flier. 40

In Figures 4 and 5, we have shown our invention in connection with an eccentric type of flier, 2| indicating the attaching sleeve thereof having a substantially cam-shaped flange 22 at its lower end which is adapted to be passed through the 45' opening 23 in the inverted cup member or ferrule 24 of the bobbin 25 during the application and removal of the sleeve to and from the spindle 26. The flange 22 is arranged to bear against the underside of the top wall of the cup member 50 in the manner shown in Figure 5. Mounted on the sleeve 2| is a wire-attaching member 21 and projecting from the diametrically opposite side thereof is a weight-balancing member 28, similar to that heretofore described, and functioning to 55 produce the same results of counter-balancing the weight and centrifugal force of the flier wires. The eccentric flange 22 is disposed in a direction crosswise relatively to the members 21, 28 so that its weight is evenly distributed in opposite sides of the flier-axis. As seen in Figure 4, the bottom or flanged end of the sleeve 2| is substantially elliptical in shape, one end of the ellipse forming the flange 22 to provide a bearing of maximum extent with the ferrule and still retaining the proper balance of the flier as well as permitting the ready application and removal of the flier to and from the bobbin.
