WILLIAM G. ESMOND BY 1m ATTORNEYS Patented Jan. 18, 1949 ADVANCING REEL wiiiiam G. Esmond, Cumberland, Md., assignor to Ceianese Corporation of America, a corporation of Delaware Application June 21, 1947, Serial No. 756,179

This invention relates to apparatus employed in the manufacture of artificial silk filaments, thread, yarn and the like, hereinafter referred to as yarn," and relates more particularly to a reel adapted to advance helices of yarn in an axial direction. The yarn may be subjected to a treatment with a fluid medium or mediums during the movement of the helices of yarn along the reel,

An object of this invention is the provision of an improved advancing reel characterized by its simplicity and strength of construction.

Another object of this invention is to provide an improved advancing reel embodying a plurality of bars which are angularly spaced with respect to each other, the-angular spacing being fixed and equal and which bars are divided into two cages adapted for interdigitating movement.

A further object of this invention is to provide an improved advancing reel in which the interdigitating and yarn advancing motions of the bars of the reel are effected by means of solenoids exerting magnetic attraction against an opposing force exerted by a suitable spring.

Other objects of the present invention, together with certain details of construction and combina-' tions of parts, will appear from the following detailed description.

As is well known, reels of the type of the reel of the instant invention which are adapted to advance helices of yarn axially comprise a plurality of spaced bars arranged circumferentially about an axis. These bars are divided into equal parts to form two cages, the bars of one cage being caused to reciprocate vertically and horizontally in a different order than the bars of the othe 10 Claims. .(Cl. 28-'-71.7)

Cir

Referring now to the drawings for a detailed description of the advancing reel of this invention, the reel comprises a plurality of bars, pref erably sixteen per cage. arranged circumferentially about shaft 8 driven by any suitable means (not shown). Two of such bars 8 and H are shown.

The bars 8 and II which alternate with each other around the reel are substantially similar in structure and comprise an elongated hollow member I! having fixed at one end thereof a cylindrical projection l3 of any suitable magnetic material. The bars 9 and II are supported in annular brackets ll attached to one end of flat springs I5, the other ends of said flat springs being attached to collars I i fixed to shaft 8 for rotation therewith.

Each of the bars 9 and II telescopes an ovalshaped solenoid H and i1, respectively, supported on shelves l8 extending between and carried by spiders l9 and 2| fixed to and rotated by shaft 8. The shelves l8 and bars 9 and H are provided with projections 22 for holding and retaining expansible springs 23 in position between the shelf and the bar. These springs 23 are adapted to maintain the bars in extended position relative to the shelves.

The shaft 8 is rotatably mounted in a bearing bracket 2| provided with openings 25 through which bolts are adapted to pass for attachment to a suitable member (not shown) for supporting the reel structure firmly and rigidly. The inner end of the bearing bracket is provided with a flange 26 on the inner face of which is mounted the commutator strip arrangement shown in Fig.

2 and generally indicated by reference numeral 21. Brushes 28W, 28X, "Y and 282, which are adapted to be in contact with the commutator strips, are mounted in one face of a drum 2!! which is fixed to and rotates with'shaft 8 and which also carries circumferentially thereof a solenoid 3| thereon for each of the bars 9 and H. Each projection l3 of the bars extends into its adjacent solenoid 3| or 3 I The interdigitating and yarn advancing motions of the yarn advancing reel of this invention are accomplished by means of the solenoids ll, ll, 3!- and 3| exerting magnetic attractions on the bars 9 and H and the projections l3, each bar 9 of one cage and each bar ll of the other cage being actuated by its solenoids l1 and 3i. The solenoid ll causes the in-and-out movement or the "interdigitation of the bar. The solenoid 3| controls the lateral movement of the bar which causes the yarn in contact with the bar to be adthe action of flat springs vanced. Each solenoid of the reel is grounded on one side and on the other is connected to a brush in contact with the commutator strips 21 mounted on flange 26. Thus, all of the solenoids l1 cooperating with arms9 of one of the cages are connected to brushes 28W (only one of which is shown, there being one brush for each solenoid or two brushes per bar) in-contact with the innermost commutator strip W; all of the solenoids I 1' cooperating with arms ll of the other of the cages are connected to brushes 28X in contact with commutator strip X; all of the solenoids 3| cooperating with projections l3 of .bars 9 are connected to brushes 23Y in contact with commutator strip Y; and all of the solenoids 3| coopcrating with projections l3 of bars I I of the other cage are connected to brushes 23Z in contact with commutator strip Z. The numbers shown on each block of each commutator strip represents the potential of that block in volts. These voltages are obtained from a transformer 32.

The interdigitation movements of the bars 9 comprising one of the cages is as follows: As the brush 28W connected to the solenoids l1 travels around commutator strip W, in the position of voltage, the bar is fully extended. As the voltage increases to 1, 2, 3, 4 and 5 volts, the bar is caused to be drawn in by solenoids l1 against the action of springs 23. As the voltage then decreases to 4, 3, 2, l and 0 volts, the springs 23 cause the bar to be extended to its original outermost position. The bars ll of the other cage are interdigitated in exactly the same manner as the bars 3 but 180 out of phase therewith.

The advancing motion of the bars is effected as follows The solenoids 3| exert no attraction on the projections l 3 of bars 9 when their brushes 26Y rest upon the portion of commutator strip Y with 0 voltage. As each brush 28Y progresses clockwise around the commutator strip Y, the voltage increases 1, This causes the bar to advance uniformly against IS. The advancing motion of the bars 9 is arranged to start before the bars are fully extended yarn and is arranged to continue until after the bars are withdrawn and away from the yarn. After the bars are withdrawn, the voltage on the solenoids 3| cooperating with the projections l3 on bars 9 drops from 18 to 15, 12, 9, 6, 3 and 0 in 2, 3, 4, 5, etc., up to 18 volts.

and in contact with the order to permit the springs IE to return the bars for the next advancing motion. The bars I I of the other of the cages are advanced and returned in exactly the same manner as the bars 9 except that the advance and return are 180 with the advance and return of the bars 9.

A flange housing 33 is attached to drum 29 for the purposes of protecting the commutator strips I and brushes from dust and moisture.
