4 Claims.

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

One of its objects is the provision of a flyer of 5 this character having an expansible journal or bearing member which is so designed and constructed as to afford a uniform and continuous bearing for the flyer irrespective of its degree of expansion occasioned. by the size of the spindle to which it is attached.

Another object of the invention is to provide a balanced flyer designed to produce an even, constant and minimum thread tension, and wherein means are provided thereon for developing or creating, during the high speed motion of the flyer, a force for counter-acting the centrifugal force developed by the flyer wires.

In the accompanying drawing:-

Figure 1 is a side elevation of a bobbin and spindle showing our improved flyer 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 perspective view of the revolving portion of the flyer-body. Figure 5 is a perspective view of the journal or bearing sleeve. Figure 6 is an end view of the flyer.

Referring now to the drawing, l indicates a spindle of the usual tapered form, and. I l a bobbin mounted thereon. The flyer body, which is detachably mounted on the bobbin spindle, preferably consists of an anchoring sleeve or journal I2 for attachment to the tapered end of the spindle, and a substantially hollow hub or bearing composed of upper and lower cup-shaped sections l3 and M, respectively, which may be in the form of stampings suitably fastened together by a lap or interlocking joint, and which contain bushings I of fiber or like material whose opposing ends terminate short of each other to provide an intervening annular space I6. The hub is free to rotate about the journal and projecting from one side of the hub is a member I! 45 upon which the flyer wires l8 are mounted, the same being retained in loops I9 formed in such member and a clamping ring or segment 20 being employed for detachably and securely holding the wires against displacement. In the drawing, two flyer wires are shown, one having a depending thread-engaging eye at its outer end, which, during the rotation of the flyer, assumes the outwardly-deflected position shown by full lines in Figure 1.

The anchoring sleeve or journal 12 fits comparatively loosely within the axial opening of the hub 13, M and by preference is split lengthwise to provide an expansible sleeve capable of ready attachment to bobbin spindles of varying diameters. Intermediate its ends the sleeve is provided with a thrust bearing which may be in the form of an annular flange 2| which occupies the space It between the bushings l5 and limits the movement of the hub axially of the sleeve. As shown in Figure 3, this flange is preferably formed integrally with the sleeve by folding the sleeve upon itself. The sleeve I2 is so split as to afiord under any normal expansion thereof a continuous and uninterrupted circular bearing surface for the flyer body. To this end the anchoring sleeve is split in a substantially zig-zag manner or laterally oiiset fashion and includes a plurality of longitudinal slit portions 22 disposed in radially different planes, and interconnected by substantially circumferentially-extending slits 23, whereby there are formed oppositely-facing tongues 24 between the longitudinal slit portions of the sleeve. These tongues, when the sleeve is expanded, span or bridge the adjoining radially offset slits and thereby provide a continuous and. uninterrupted circular bearing surface for the flyer body under any normal expansion of the sleeve. The bushings l5 of the flyer body engage the journal above and below its thrust-bearing flange 2| and the circumferentially-extending slits 23, immediately adjoining such flange, are located so that they lie in planes which intersect the respective bushings, whereby upon expansion of the journal sleeve when applied to the spindle, the bushings have a continuous bearing contact with the adjoining tongues 24 of the journal across those portions thereof where gaps are present due to the expansion of the sleeve. The thrust flange 2| of the journal has a plurality of radial notches 25 which intersect the journalwall and which permit the necessary and uniform circular expansion of the journal.

Projecting from that side of the flyer-hub diametrically opposite to that of the flyer wire supporting member I1, is a member 26 which provides a means for counterbalancing the weight of the flyer wires and their attaching means when the flyer is at rest, and which is further so designed as to develop or generate a force to counteract the centrifugal force developed by the flyer wires when the flyer is in motion. For this purpose, the side portions of the member 26 at opposite sides of the radial center line thereof are reversely bent or deflected out of the horizontal to provide air-impinging surfaces 21, the air impinging against the underside of one of such surfaces when the fiyer is traveling in one direction and against the top side of the companion surface when the fiyer is turning in the opposite direction. The outer end of said member 26 is preferably shaped in the form of a broad V and the resulting edges thereof are curled or bent, as indicated at 28, to provide air-impacting surfaces or pockets. These pockets converge inwardly toward the center line of the member 26 and terminate at the apex of the V, at which point the air directed into the pockets is centrifugally discharged. By this construction, the air directed by the deflecting surface 21 against the companion curled surface 28 exerts a pulling force or thrust effect on that side of the fiyer body which serves to counteract the centrifugal force developed by the flyer wires, with the result that the flyer revolves evenly and uniformly about the spindle to maintain an even tension on the threads at variable speeds. Furthermore, by constructing and shaping the member 26 as described, the resistance to the rotation of the fiyer is reduced to a minimum and at the same time there is accomplished the centrifugal force developed by the flyer wires.

By preference, we provide washers 29 between the opposite faces of the journal-flange 2| and the bushings I which afford a metal to metal contact and insures ease of operation of the fiyer about the journal.

We claim as our invention:--

1. A flyer for spinning machines, comprising a hub, a fiyer wire projecting from one side of said hub, and a member projecting from the diametrically opposite side of said hub for generating a force counter to that of the centrifugal force of the wire when the flyer is in motion, the opposite side portions of said member adjacent its outer end being reversely bent to provide airimpacting surfaces.

2. A flyer for spinning machines, comprising a hub, a flyer wire projecting from one side of said hub, and a member projecting from the diametrically opposite side of said hub for generating a force counter to that of the centrifugal force of the wire when the flyer is in motion, the opposite side portions of said member adjacent its outer end being reversely bent and said member terminating at its outer edge in oppositely curled portions to provideair-impacting surfaces.

3. A flyer for spinning machines, comprising a hub, a flyer wire projecting from one side of said hub, and a member projecting from the diametrically opposite side of said hub for generating a force counter to that of the centrifugal force of the wire when the flyer is in motion, the opposite side portions of said member adjacent its outer end being reversely bent and said member terminating at its outer edge and at opposite sides of its radial center line in oppositely curled portions to provide air-impacting pockets, the latter converging inwardly toward the center line of said member.

4. A fiyer for spinning machines, comprising a hub, a flyer wire projecting from one side of said hub, and a member projecting from the diametrically opposite side of said hub for generating a force counter to that of the centrifugal force of the wire when the flyer is in motion, the opposite side portions of said member adjacent its outer end being reversely bent out of a horizontal plane and the outer end of said member having a substantially V-shaped notch therein, the edges forming said notch being curled in opposite directions, respectively, to form air-impacting pockets, the latter converging inwardly and the apex of the notch forming an outlet for the displacement of the air.
