Patented June 20, 1944 SPOOLING APPARATUS Carl J. Dentzer, Parma, Guy W. Shnrmer, Warrensville, and Otto J. Vanek, Cleveland, Ohio, assignors to The American Steel and Wire Com- Bey pany oi New Jersey, a corporation of New Jer- Applicatlon October 1, 1942, Serial N0. 460,434 13 Claims. (Cl. 242-25) The present invention relates to improvements in apparatus for spooling wire in separate batches periodically as the wire accumulates on a rotary or stationary block of any conventional form of wire drawing machine. The novel features relate to the improved structural arrangement and coordination of parts or equivalents thereof such as shown in the accompanying drawings and defined with particularity in the appended claims.

For a more complete understanding of the invention, reference should be made to the accompanying drawings, the following detailed disclosure and the appended claims.

In the drawings:

, Figure 1 is a plan view illustrativev of a preierred construction of the machine embodying the present invention;

Figure 2 is a view partly in side elevation and partly in section as indicated by 4the staggered line II-II of Figure 1;

Figure 3 is a fragmentary transverse section-on line III-III of Figure 2;

Figure 4 is a transverse section on line IV-IV of Figure 2;

Figure 5 is a detailed view illustrating a traversing mechanism taken on line V--V of Figure 2;

Figures 6 and 7 are, respectively, a plan view and side elevation of parts shown in Figure 5 with portions broken away and shown in section in the interest of clearness; and

Figure 8 is an elevation illustrating a modification oi a reel rotatable on a vertical axis.

Referring in detail to the drawings l0 and i2 represent respective end vframes to which there is secured a platform I4 supporting the main drive moto' I6, and a. top plate l8.which serves as a supporting base for many component parts of theI mechanism to be described. The armature shaft of the motor I6 carries a double grooved pulley 20 around which is trained a parallel pair of the belts 22 transmitting the motor drive to a double grooved pulley 24 secured to a countershait 26 mounted in suitable bearings 28 carried by the frame structure of the machine.

'I'he shaft 26 near one end carries a pulley 30 which is connected by a 4belt 82 to a pulley 84 keyed or otherwise secured to a hollow trunnion 36 journaled in bearings 31 which serve to rotatably support a filer 38.

As shown at the left in Figures 1 and 2, 40 represents the fixed block of a continuous ilne wire drawing machine. One extremity of the block is suitably supported by an upright 42 carried by a; bracket 44 secured to the end frame I0 of the machine. The block 46 as illustrated is oi skeleton form and it may be of considerable length so as to provide for the accumulation of an extremely long coiled bundle 46 of line wire, say three or four feet in length by about one foot in diameter. The wire of the bundle 46 may be regarded as having accumulated over a long period oi time as the result of a conventional wire drawing operation, for example, the same mayaccumulate continuously for several hours on the block 46 as the wire drawing operation proceeds. The machine of the present invention is arranged to withdraw the f wire from the bundle in intermittent stages and to accumulate it in separate batches on separate spools in a rapid yet reliable manner. The spools are carried by a rotatable turret which the operatorI manually turns and locks in desired positions as hereinafter described.

The trunnion 36 of the ilier 38 has a central longitudinally extending passageway 46 formed thereon. An inner grooved guide sheave 50 is rotatably mounted on the iiier and is adapted to guide the longitudinally advancing wire w in its outward travel where it passes over guide sheaves 52 and 54. From the guide sheave 54 the wire passes to and around another guide sheave 55 thence between straightener rolls 56 and around guide sheave 51 to the point 58 where it is fastened to the spool 60. The stretch of wire between the sheave 64 and the sheave 51 is in a plane or zone extending beyond the end of the flyer. Each spool 66 is carried by a respective one of a plurality of rods 62 secured to bosses 63 radiating from a turret 64 rotatably supported on a trunnion stud 66 secured to an upstanding hub 68 formed on a horizontally reciprocating carriage 10.

As the hier rotates it will turn counterclockwise as indicated by the arrow in Figure 4. Each spool is normally held stationary on its supporting rod 62 radiating from one of the bosses 63 of the turret by a clamp nut 14. As the flier rotates the wire will be pulled around the several guide sheaves and wrapped in coils around the spool which has been aligned with the'axis of the rotating iiier. A spring pressed locking pin 15 coacts with recesses 11 to releasably hold the turret in position to align any one of the several spools with the 111er. l

As each convolution is pulled from the bundle 46 it passes through the restricted space between spring fingers 16 and the outer periphery of the Y iixed block. This provides for a smooth or uniform pay-olf of the wire from the bundle. From the block the wire passes between tension plates 18 and 80 the latter being adapted to be adjusted by manipulation oi a tension screw 82. As the spool is moved longitudinally in relation to the hollow trunnion4 88 the wire will be distributed uniformly thereon. To this end vmeans are pro` vided for traversing the turret supporting carriage 18. The traversing mechanism is best shown in Figures 5 through 7. The base 18 of the carriage is of dove-tail form as shown in Figure 3 so as tol slide in the gib groove 84 of the carriage guide 86 which is bolted t0 the top plate Il afsv by a countershaft |82. This shaft carries a conepulley |84 which is connected by belt |88 with a similar. cone pulley |88 mounted the aforesaid countershaft 28.

The push rod 88 carries a sleeve 8 provided with downwardly extending arms ||2 and ||4 whose lower extremities are forked at I8 and I8 so as to fit over a ilxed guide rod I 28. Surrounding the sleeve ||8 there is a sleeve |22 which is rotatable thereon. 'Ihis sleeve 22 carries respective arms |24 and |28 which carry respective half nuts |28 and |88 adapted to be periodically engaged with the feed screws 88 and 88. As shown in Figure 5 the haii nut |28 is in cooperative feeding relation with the feed screw 88. At this time the rotation of the screw will feed-the carriage and turret supported thereby to the left as shown in Figure 2, and therefore toward the flier. During this movement of the spool toward the left, the same enters a central recess formed in the end of the flier as suggested by the dotted portion of the spool shown in Figure 2. After the spool has been moved a suillcient distance to the left to cause the wire being accumulated to-contact the right flange of the spool, a follower |82 will strike a'cam member |84 secured to an adjustable plate |88. This will rock the arm |24. thereassises block to control the pay-od of successive convolutions of the coil and means for exerting a tension on the wire after it is released by the.

" flipper fingers from which tension means the by disconnecting the-nut |28 from the feed screw 88. At the same time, the arm |28 will be rocked so as to engage the nut |88 with the feedv screw 98. Thus the direction of movement of the carriage will be reversed. When the carriage has moved a predetermined distance, depending upon the longitudinal distance between the flanges on the spool, another cam |88 carried by an adjustable support |48 will come into play and shift positions of the half nut. In this manner, the traversing mechanism will distribute the winding uniformly lengthwise of the spool as the same is shifted longitudinally ilrst in one direction and then in the opposite direction.

From the foregoing, it is apparent that our invention provides apparatus for winding wire on a spool comprising either a rotary or stationary block for supporting a coiled bundle of wire and rotary means such as the flier for withdrawing the wire from the bundle and winding it around a spool, and that the spool support is in the nature of a rotatable turret carrying a plurality of arms ixedly positioning respective spools thereon in such manner that the spool supportwire moves longitudinally through the hollow trunnion oi' the `flier and around the guide sheaves carried thereby to a zone outwardly of and beyond the extremity ofthe flier head which is'remote from the trunnion. From this point beyond the ilier head the wire is distributed uniformly lengthwise of the spool by reason of the factthat the traversing mechanism automatically moves the spool back and forth at a rate properly coordinated with .the winding motion and the pitch or advance of the feed screws.

An important advantageous feature inherent in the described mechanism is that the spool is held stationary and the wire is wound thereon at a higher rate of speed than that obtainable by conventional apparatus heretofore generally used. The improved machine shown herein has been successfully operated at spooling speeds ranging from 900 to 2600 feet per minute, which is approximately four timesv faster than prior art practice, and still higher speeds are believed to be readily obtainable. One governing factor in the high speed spooling of wire is the tendency of the wire leaving the bundle to snarl or tangle. This tendency is largely overcome in the machine of our invention by the above described spring flipper ilngers and tension plates which are effective in the combination to control the uniform pay-oil of wire from the bundle.

The invention makes possible. an important saving since wooden spools can be successfully used in place of the more expensive metal spools heretofore required forv high speed spooling. Since the wooden spools in .the machine of our invention are held stationary, there is no danger of their iiying to pieces undei the influence of centrifugal force as they would very' likely do if rotated at a speed comparable tothe rate of wire travel obtainable by use of our improved machine.

In the embodiment of the invention illustrated, the block from which the wire is paid oi! is normally stationary. It is to be understood, however, that the invention also .contemplates paying the wire olf from a rotary reel or block.V

While we have described quite precisely the construction and arrangement of coacting instrumentalities which an actual reduction to practice has shown to be highly desirable, it is not to be construed that we are limited thereto, since various modifications may be made by those skilled inthe art without departure from the invention as defined in the appended claims.
