5 Claims.

This invention relates to certain new and use-' ful improvements in the fliers employed in connection with spinning machines and the like.

It has for one of its objects to provide a simple and efiicient flier whose parts are so designed and constructed as to eliminate the use of lubricants and thereby prevent the threads being soiled during spinning.

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 l is a fragmentary front view of a portion of a spinning machine showing my improved fiier applied thereto. Figure 2 is an enlarged top plan view of the flier and associated bobbin. Figure 3 is an enlarged fragmentary vertical section taken on line 33, Figure 2. Figure 4 is an enlarged horizontal section taken on line 4-4, Figure 3.

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

This invention is applicable to spinning machines of well known construction, I indicating the bobbin-spindle and [I the take-oil bobbin mounted thereon. The thread or yarn from the bobbin extends upwardly through the eyes of the usual flier wires I 2, I3 mounted on a holder or wire-base l4, and thence is guided upwardly through a guide or centering eye l5 to a take-up spool (not shown).

The flier body to which the wire-base M is attached, is in the form of a self-contained unit so designed that the use of lubricants is eliminated and the bearing member associated with the wire-base readily replaceable when worn out without disturbing the rest of the flier body. This flier body consists of a split expansible anchoring sleeve I 6 adapted for frictional engagement with the tapered end of the spindle H), a journal member I! disposed about the sleeve for rotation relative thereto, and a bearing member l8 rotatably mounted on the journal member and to which the wire-base I4 is attached. Intermediate its upper and lower ends the sleeve I6 has an external flange or thrust shoulder l9 and the journal member is provided at its lower end with an internal socket 20 about the thrust shoulder for limiting the axial displacement of the journal member. As shown in Figure 3, this socket may be formed by providing the lower end of the journal member with a flange 2i and attaching to this flange a cup-like member 22. The sleeve and journal member I! are preferably made of metal,

while the bearing member [8 to which the wirebase is attached, is preferably made of fiber or like material.

The bearing member 18 is more or'less freely mounted on the journal. member, being detach- 5 ably retained against limited axial displacement at one end by a shoulder 23 formed adjacent the lower end of the journal member, while the upper end of the latter has a detachable, split band 24 forming a shoulder for limiting the upward dis- 10 placement of the bearing member. When applying or removing the bearing member, the split band 25 is removed from the journal member.

While manifestly simple in construction, thisimproved flier renders the use of lubricants un- 15 necessary and thereby prevents soiling of the threads, and furthermore it enables the ready replacement of the fiber bearing member when worn, thereby reducing the-maintenance costs of the fliers to a minimum.

I claim as my invention: 1. A flier for spinning machinesand the like, comprising a split expansible sleeve adapted for attachment to a bobbin-spindle, a journal member disposed in spaced relation about said sleeve for rotation relative thereto, complementary means on the outer and inner faces of said sleeve and said journal member, respectively, for holding the latter against limited axial displacement relative to the former, a bearing member detachably mounted on said journal member, and a wire base attached to said bearing member.

2. A flier for spinning machines and the like, comprising an expansible sleeve adapted for attachment toa bobbin-spindle, a metal journal 5 1 member disposed in spaced relation about said sleeve for rotation relative thereto complementary external and internal means on said sleeve and said journal member, respectively, for holding the latter against limited axial displacement rela- 40 tive to the former, and a fiber bearing member mounted on said journal member and having a wire-base borne thereby.

3. A flier for spinning machines and the like, comprising a split, expansible sleeve adapted for attachment to a bobbin-spindle and having a thrust shoulder thereon, a journal member mounted on the sleeve for limited axial displacement relative thereto and having a socket therein into which said thrust shoulder freely extends, 50

and a bearing member detachably mounted on said journal member and having a wire base borne thereby.

4. A flier for spinning machines and the like,

comprising a split, exp-ansible sleeve adapted for attachment to a bobbin-spindle and having a thrust shoulder thereon, a journal member mounted on the sleeve for limited axial displacement relative thereto and having a socket therein into which said thrust shoulder freely extends, said journal member having a fixed bearing shoulder adjacent one end thereof and a detachable bearing shoulder adjacent its opposite end, and a bearing member having a wire base thereon detachably mounted on said journal member between its bearing shoulders.

5. A flier for spinning machines and the like, comprising a split, expansible sleeve 'adaptedfor attachment to a bobbin-spindle and having an external thrust shoulder thereon intermediate its ends, a metallic journal member mounted on the sleeve for limited axial displacement relative thereto and having an internal socket therein about said thrust shoulder and an external bearing shoulder adjacent the lower end thereof, a detachable bearing shoulder applied to the upper end of said journal member, a fiber bearing member detachably mounted on the journal member for limited axial displacement between the hearing shoulders thereof, and a wire base attached to said bearing member.
