Be it known that l, THOMAS Mincnnr, a citizen of the United States of America, residing at Hampden, in the county of Hamp- 5' den and State of Massachusetts, have linvented certain new and useful lmprovements in a Winding Device, of which the following is a specification. f My present invention i's directed to iinl@ provements in devices for winding up a continuous web as the latter is fed from a web *making machine as in paper manufacture or web treating machine as in rubber manufacture and has general. utility-in analogous situations.

bodiment as arranged for winding up a raw rubber coated `web as fedfrom a calender and this embodiment is illustrated in the accompanying drawings, in which:

Fig. 1 is atop plan view of the device, the ri ht hand half being broken away;

Briefly summarized, the device comprises a plurality of take-up spools .so arranged that they may successively be brought into operation and vreceive from thel calender Without interruption the sheet material delivered by it; These spools are preferably arranged so that they may be shifted` by power to their active or inactive positions, and so that the speed with which they wind up the stock maybe' varied to accommodate the varying surface speeds of full or empty spools. f

For these and other purposes which will appear the device is preferably constructed as will now be described. journaled directly in standard 11 and at its other end journaled in a sleeve 1'3 freely ro` tatable in the standard 10. The sleeve 13 and shaft 12 are driven as will be described later. Keyed to shaft 12 are arms 14 and 15 spaced apart by the flanged tube 8O and eX- tending both ways from the shaft and furnishing end bearingsfor a plurality of rolls which will be described. The outer ends of the two arms are preferably held in their My invention will be de-l scribed in connection with a preferred em-` Y l proper spaced relation by the rods 16 and at their ends provide bearings 17 for shafts 18 carrying by any suitable detachable connection windup rolls v19 such as illustrated in Fig. 7. ln this figure the end of roll 19 is shown as having a squared end 81 fitting in a 'slot in the endlof shaft 18. A col-lar 83, slidable from the locking position lshownl in full lines to the inoperative position shown in dotted lines, has a lug 81 sliding over the squared end 81 to constrain the'roll for rotation with the shaft and' to hold it in central position. When the collar is moved to inoperative position this lug is received wit in a recess 85 in the'shaft 18. Cooperating with these wind-up rolls are liner supplying spools 2O detachably mounted in a like manner to rolls 19, and which carrysheet material 21` adapted to be wound uponone of arms 24, and adjustable by means of' apawl and ratchet 27 arranged to hold the shaft in any desired position, serves to press the brake yieldingly against the liner roll.

In order to bring either of the two windup devices alternately into operative position the arms 1-1 and 15 are provided with mechanism for rotating them through 130. To this end sleeve 13 has secured for rotation with it a sprocket 30 which may be constantly driven from any suitable source of power. Splined on shaft 12 are disks 31 and 327 dislr 31 having a flange-33 abutting against a shoulder-34 on shaft 12, .and disk 32 being freely reciprocable' on the shaft through a short distance although constrained to rotate therewith by its splined connection. Sleeve 13 has -a flange 35 formed on one end -which is fitted with -holes 36 adapted to loosely receive dowels 37. secured to' a dislr 38 interposed between disks 31 and '32. Friction lining 39, carried .by disks Bland 32 serves to cause these disks to grip the disk 33 for rotation therewith when the three disks are pressed together. To cause this pressure when desired the end of shaft 12 is threaded as at Oto receive a hand when nfvivhieh serves to adjust the 42 between 'which and 43 mounted as onpins osition of Ia plate disk 32 are springs 44 on the plate. When the hand wheel is screwed up it increases the spring pressure with which the friction disks are held to. gether, and thus provides an adjustment by which sleeve 13 and shaft 12 are frictionally j lined together forrotation. It will be apparent from theabove description that by turning the hand'wheel the arms 14 and 15 can be caused to rotate with shaft 12 under the influence of power sprocket 30. i

lIt is desirable to provide means to stop the rotation of the arms after they have rotated through an arcy of 1800 Aso as to bring one or'the otheruof'v the winding-up rolls into operative position.v In order to accomplish this I provide. arm 45, havlng on its outer face adoublescroll cam 46 provided with diametrically opposite' locking recesses 47.',The'boss also carries detent. tripping cams 48. Reciprocable in a ide 49 lon frame 11 is a'slide 50 to 51 (shown broken away in Fig. 5) having at its` other end. a

slet .52 embracing a pin 53 on an arm 54A extending from a rock shaft 5,5. Also secured to this rock shaft is a treadle 56, normally pressed upwardly by a spring 57, by means of which the slide 50 maybe lowered. may serve as the pivotedconnection with pitman 51, resting upon the top `of a pluns ger 59 operating in a casing 60 and pressed yieldingly upwardly` by a spring 61. i On the upper end' of the slide isa detent 62 cooperating with cams- 46 and 48 as will now'vbe described.; z

As treadle 56 isidepressed detent 62 is withdrawn from the lockingirecess 47 in which' it was' held by spring 61. y arms 14 and 15 are rotated. by driving the connection to sprocket 30 eected by'turning hand wheel 41',v as above described, and treadle `56 released. The depression of tre'adle 56 and the connection to sprocket 30. is preferably made at about thel same time. 'I he detent will then drop into the succeeding recess '47 and will both stop further rotation of the arms and hold them in position until treadle 56 is again depressed. The hand wheel 41 is thenturned to disconnect the driving connectionbetween the sprocket 30 and the arms 14 and 15. If the operator neglects to release the treadle after starting the -rotation of the arms the detent 48 -will raise the [detent into locking position. This will serve as a reminder-'to the operatorto get his foot off the treadle because the latter rises'with the detent. It will be seen that by this means the arms are-kept against a rotation of more than180o or from one normal position to supplied through 15" with a circular boss.
