MICHAEL C. MCDZRMOTT Ff/iww/ W ATTORNEY Patented Jan. 22, 1952 FLIER Michael 0. McDermottICleveland, Ohio, assignor to Industrial Rayon Corporation, Cleveland, Ohio, a corporationof Delaware Application March 16, 1949, Serial No. 81,802 6 Claims. (01-. 57116) i This invention relates to fliers More particularly this invention relates to fliers of the type used in textile twisting and spinning machines. In the twisting of yarns of heavier denier it is desirable to restrict a flier in rotation during certain periods to substantially the rotation of a supply spool to prevent yarn and the like from over-running the spool when the spool is decelerated or stopped. The over-running of yarn usually causes corkscrews and a backing up the spool. Then, before the twisting machine of twist to the point of departure of the yarn on is restarted the corkscrews have to be' eliminated; and where a great many spools are attended by an operator a considerable time is taken in readjusting the yarn. Sometimes the f corkscrews are carried through the flier onto a collecting spool occasionally breaking the flier; and should the imperfect portion pass through the flier eye the collected yarn is defective and it will create further difficulties in later processing steps. Also, a corkscrew may back up to the surface of the spool and the twisted yarn may become ensnarled with the laid turns on the spoolto damage the yarn.
Various types of fliers have been devised having braking means to restrict the independent rotation of the flier at spool starting and stoprotation between the flier and the spool,
The mentioned braking devices generally have been found not suificient in the control of yarn upon deceleration so as to be adaptable in the spinning of heavier denier yarns. This invention, advantageously provides a flier for use with such yarns. The flier has an integrated braking device in addition to an air-brake which operates to restrict the rotation of the flier to that of the spool at starting or stopping periods. Further the flier is advantageously provided with a combination air-brake and air-lift device which is adapted to disengage the braking means and allow the flier to rotate independently of the spool.
Generally, the flier comprises a mounting adapted to be placed about a spindle protruding above a spool of yarn, a sleeve about this mounting, and a sleeve about the latter sleeve carrying the guide eye of the flier and the air-brake lift. The :inner sleeve has a flared, conical, section and the surrounding sleeve, being adapted to iii rotate relative to the inner sleeve, also has a conforming flared section. When at rest, or substantially so, the outer sleeve rests on the flared section of the inner sleeve. During rotation, however, the air-brake lift acts to raise the flier off the flared section of the inner sleeve.
The advantages of the flier will be more thoroughly explained in the following description and in the accompanying drawing where:
Figure 1 represents in elevation the flier of this invention;
Figure 2 is an isometric view of the flier; and
Figures 3, 4, 5 and 6 are sectional views of the flier taken along lines 4-4, 5--5 and 6-6 respectively. V p
, Referring to the drawing, a thread I0 is withdrawn from a supply spool through a flier I3 positioned about a spindle l2 supporting the spool The thread is led through the flier eye 20 and from thence to a further forwarding or collecting device. The flier l3 generally comprises a body portion I5 having at one end an airlift brake l6 and at the opposite end. an arm I! containing the fliereye 20. e p
In the body portion of the flier, as shown in Figure 2, there is positioned the flier supporting sleeve 2| which is adapted to rotate about an inner sleeve 22 also having within it a further pressure fitted sleeve 25 which is adapted to be frictionally positioned about the spindle 2. The flier body I5 is provided with an aperture through which extends the flier supporting sleeve 2|. The flier body I5 is positioned about the sleeve 2| in a press fitting manner and it is held securely thereto by a locking washer or ring 26. Thus secured the sleeve 2| is adapted to rotate with the flier body I5. The sleeves 25 and 22 flt snugly together and both are adapted to rotate with the spool spindle l2.
As'shown in Figures 3 and 4 the sleeve 22 has an outwardly flared conically shaped bottom portion 24 and the lower portion of the flier supporting sleeve 2| has a complementary out wardly flared section 29. When the sleeve 2| is raised free of the flared section 24 it is then adapted to rotate relative to the sleeve 22 and independently of the spool however, when the sleeve 2| drops, as by gravity, into frictional contact with the flared portion 24 it becomes bound. thereto to rotate at substantially the same speed as the sleeve 22 and the spool l About the cylindrical portion 23 of the sleeve 22 there is provided a vertical limit stop such as collar 21 for the flier body. The collar 21 is fitted about the sleeve 23 and it is retained in position by a locking device 28; both the collar 2! and the locking device 28 are positioned in grooves provided for them in the sleeve 22. The innermost sleeve 25 extends outwardly of the sleeve 22 at both endsand it is crimped therewhich is advantageously angularly positioned to the direction of travel as shown in Figure 5. The
Where it is deemed that'the raising'a'ction" of the flier'air brake I6- is not effective soon enough upon starting a twisting operation then the lift of the flier can be further increased bytapering the body portion [6 to the direction of its rotation; When the flier body is formed with reinforcing ribs or side braces, such as the ribs 30, 3! shown in Figure 6, theribs are desirably angularly positioned to thedirection of their rotation.
