FLIER SPINNING DEVICE.

Application filed October 1, 1913. Serial No. 792,745.

To all whom it may concern:

Be it known that I, JAMES J. BIBBY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Flier Spinning Devices, of which the following is a specification.

My invention consists of a device of the flier type for spinning an untwisted roving into a twisted yarn or thread or for twisting together two or more strands of thread or yarn. Hereinafter for convenience, and to avoid repetitions, I will refer to the device as a spinning machine for producing a twisted thread from an untwisted roving.

One object of my invention is to so guide the roving in its travel over the flier as to prevent it from being thrown outwardly from the flier by centrifugal force or from being disarranged by air pressure upon it gs it is rapidly carried around with the ier.

A further object of my invention is to prevent displacement of the flier from its proper plane of rotation and to effect such rotation with a minimum of friction, and a still further object is to insure the winding of the thread in a firm mass or body upon the spool or bobbin.

These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in which Figure 1 is a vertical sectional view of aflier spinning device constructed in accordance with my invention; Fig. 2 is a horizontal section on the line a-a, Fig. 1; Fig. 3 is a horizontal section on the line bb, Fig. 1, and Fig. 4 is a side elevation of the bearing stud for the lower end of the flier.

In the drawing, 1 represents part of a projecting arm or bracket which carries the upper bearing for the flier, 2 part of the fixed rail which carries the stud constituting the lower bearing for said flier, and 3 part of the vertically reciprocated builder rail which carries the non-rotating spindle 4: upon which the spool or bobbin 5 (hereinafter for convenience referred to as a spool) is mounted.

The flier consists of opposite arms 6 connected at the top by a bridge piece 7 to which is secured a conical block 8 free to turn in a lubricating\ block 9 secured to the upper hearing so as to render un Patented J an.

necessary the application of oil to said top bearlng of the flier.

The opposite arms of the flier are preferably connected at their lower ends, as by segments 10, so that this portion of the flier constitutes a cylindrical shell, and they may also be connected at an intermediate point, as by segments 11, so as to'impart to the flier a degree of rigidity which will prevent distortion or displacement of either conical top of the flier so that the roving supplied to the flier through the central eye 15 in the upperdarm 1 will be confined in its passage from said eve to. the delivery eye16 of the flier and will be prevented by the outer flange of the rib 12 from being displaced radially by reason of centrifugal force while the radial web of said rib" 12 will protect it from displacement which m ght otherwise be caused by the action of the air upon it as it is rapidly rotated with the flier arm. i

The stud 17 is tubular and has an annular flange 18 and a depending tubular stem 19, the flange resting upon the top of the fixed rail 2 and the stem passing through an opening in said rail and being threaded at its lower end for the reception of a nut 20, the latter bearing upon the under face of the rail and serving to secure the stud 17 thereto. The flier has, at its lower end, a depending tubular sleeve 21 adapted for the reception of a belt whereby it can be rotated, said sleeve having projecting flanges 22 and 23 which serve to retain the belt in its proper position on the sleeve, the lower flange 23 having in its under face an annular groove forming a race for a series of balls 24: which run in a similar race formed by an annular groove in the upper face of the flange 18 of the bearing stud 17. This ball bearing at the lower end of the flierand the bearing block 9 at the upper end of the orrrc;

is, rare.

flier serve to retain said flier in its proper I A Copies off'thls patentmay be obtained for end, a step or button resting upon a correspondinglv formed seat in the-Vertically reciprocating builder rail 3.

' The spindle 4: has a conical upper end which is adapted to a seat atthe upper end of a tubular sleeve 26, the latter surrounding the upper portion of the spindle and having, at its lower end, a flange 27 upon of the stud through the opening 30 in the depending sleeve 21 of the flier, is distributed through the surface of the stud,

properly lubricates the bearing provided thereby, and finally gains access to and lubricates the ball bearing 24 interposed between the flange 23of the sleeve 21 and the flange 18 on the stud.

The roving passes first through the eye 15 in the arm 1, thence down through one of the slots 14 in the conical cap 8 of the flier, and thence, through the groove 13 in the .rib 12 on one'of'the arms 6, to the'delivery eye 16, from whence it passes to the spool 5 and is wound thereon. As the flier rotates. in the direction ofthe arrow, Fig.

- 2, the spool is caused to rotate therewith by reason ofthe. pull of the thread as it is wound upon the spool, but a firm, close windingof the thread upon the spool is insured by reason of the braking effect of the friction ring 28 and of a similar friction ring 31 interposed between the base flange 27 of the sleeve'26 and a flange at the top of a sleeve 32 which surrounds the spindle 4, extends down. through the stud 17 and its stem 19, and is, at a point below the rail 2, acted upon by a weighted lever 33, whereby its upper flange may be caused to press upwardly against the washer 31 with any desired degree of force less than that necessary to liftthe weight of the sleeve 26 plusthat of the spool and its load, so as to regulate the degree of frictional retardation exerted upon the sleeve 26, and thence upon the spool 5.

The guide rib'12 may, if desired, be formed upon only one of the flier arms 6 but it is preferable to form such rib upon both of the arms in order that the flier may be properly balanced.

I claim: The combination, in a spindle, a sleeve rotatable on said spindle, a spool carried by sa1d sleeve, a friction device actmg upon sa1d sleeve, another sleeve carryingsaid friction device, and av five cents eaohfby addressing the Commissioner of Patents, Washington, D. G."
