CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS MECEANISM FOR AND METHOD OF CQILING WIRE OR THE LIKE Application :tiled April 16,

` employed, for coiling, spooling, or take-'up purposes.

The primary object is toprovi'de anonstop method for enabling wire, or other flexible member, to be'coiled or spolole'd, and to such purpose. The invention vnds an eX- ceedingly usefu application tothe purpose of coiling or spooling Wire as it comes from the wire drawing 'die or dies. It may however be applied to various situations where it is desirable to coil or spool wire, or other flexible member.V

The present application constitutes a modiiication of the invention set forth in my pending application for Letters Patent of the United States, Serial Number 442,024, filed February 3, 1921. Other embodiments are shown in my pending applications, as follows No. 611,061, filed January 6, 1923; No. 611,- 062, filed January 6, 1923; No. 626,833, led March 22, 1923; No. 626,834, filed March 22, 1923. l

In the present embodiment of the invention, I employ aself-discharging drawing capstan or drum, which has a stationary axis. That is, in this case, the self-discharging capstan is non-travelling, in the sense that it-is not bodily movable. It is non-planetary, that is'it does not travel an. orbit, as distinglished from constructions shown in other pending applications.V The wire, or other flexible member, is discharged from the selfdischarging capstan and is suitably coiled; or

it maypass to suitable take-up mechanism andbe deposited on spools. l

The invention is illustrated in a preferred embodiment in theaccompanying drawing, in which v 4- v A Fig. lprepresents a broken plan view of mechanism embodying the invention, said mechanism including take-up or s'pooling mechanism; and Fig. 2 represents` a view partly in elevation and partly in llongitudinal section, of the mechanism shown in Fig. 1 In the construction illustrated, A represents provide improved mechanism for eifecting `1923. serial No. 632,357.

a-frame which may be of any suitable construction; B, a self-discharging capstan having associated'therewith a yielding presserdevice l', which operates to yieldingly clamp convolutions 1 of the wire, or other fieXible member la, to the winding-drum or capstan B; and C, take-up mechanism, or spooling mechanism, associated with theself-discharging capstan. Y

The winding-drum, or capstan B is fixedly secured on a shaft 2 equipped with a beveled gear 3 which is actuated by a longitudinal meshing with the gear 3. The presser-device B is shown as comprisshaft 4 equipped with a beveled pinion 4a i ing a yielding' or spring frame 5, equipped with presser-rollers 5a which serve to press the'convolutions 1 against the capstan B. The frame 5 is equipped with a stop. 5b which engages a stop 6 carried by the main frame A, thus preventing the presser-device from being carried around with the`capstan.

The spooling mechanism C comprises a` pair of spindles 7 and 8, upon which are removably mounted spools 7a and`8. These spindles are actuated by friction-disc connections 9 shaft 4.

It is necessary, in the operation of the machine, to provide for Aa distribution of the wire upon the spool which is being filled, and for shifting the wire, periodically, from the filled spool to afresh spool. This is accomplished by means of a, distributing arm 10, combinedwith suitable mechanism. The

between the spindles and the v arm 10 is equipped at its free extremity with p -themain frame, the shaft 14 is equipped with a pinion 14B. The slidel 15 is equipped with a cam stud 15a which engages a caml groove 15b with which the large cam wheel 16 is provided. The cam wheel 16 is mounted on a shaft 16a which is rotated by a bevel gear 17, driven from the shaft 4 through the medium of a pinion 18. The cam 16 reciprocates` the slide 15 regularly so as to effect distribution of the wire on the spool which is being filled. Periodically, it is necessary to shift the distributing arm 10 from one side of the machine to the other. This is accomplishedy by meansof a rack 19 which is provided with guide-slots 19n engaged by studs l9bdepending ,from the slide 15. The rackv 19 is equipped with a cam stud 19 which is adapted to be actuated by a control drum 20 whichL is mounted on a shaft20a. The shaft 20a is actuated from the shaft 162L through the medium of gears 21 and 21a. Any desired ratio of gears may be employed at this point, depending upon the timing period of the rack 19. The control drum 2O is/equipped with cams 20b and 20 which are suitably beveled,

as shown, to effect shifting of the rack 19 through the medium of the cam stud 19.

In the position vshown in the figures, the cam 20 has operated to shift the rack 19, and

thus has thrown the distributor arm' 10 to the position shown in Fig. 1, where it will serve to distribute wire on the spool 7a. By the' time the spool 7a is filled, the cam 20 will have advanced suiiciently to engage the cam stud 19c land effect shifting ofthe rack 19 in such direction as to throw the arm 10 over into position to ydistribute wire on a' fresh spool placed upon the spindle 8.

The wire becomes severed when the winding upon the fresh spool begins. .--An' attendant can then removethe filled spool and apply a fresh spool, without stopping the operation of the machine. 4 v y vAnysu'itable timing'mechanism may be l employed for regulating the number of`turns of wire to be placed on a spool; A simple way of effecting variation in the number of turns of wire to be placed upon a spool is to replace the gears 21 and 21a by other gears of a diifer Where, as in the illustration given, the wire passes from' vthe self-discharging capstan to the take-up mechanism, it is unnecessary to place the wire under any greater tension between the discharge capstan and the take-up mechanism than is essential to produce reasonably taut winding of the wire on.

the spool. This renders it feasible to employ the improved mechanism in connection with take-up mechanism having provision for shifting the wire from one spool to another, fin combination with a high speed wiredrawing machine. It is unnecessary that there should occur" even an instantaneous slacking of the operation of drawing thewire from the finishing die of the wire-drawing machine, and thus the wire-drawing tensionV What I regard as new and desire to secure by Letters Patent, is:
