21 Claims. A(Cl. 242--66) This invention relates to Winding machines, andone object of the invention is to provide improved mechanism for driving the pressure roll which, in .machines of the type involved, acts upon the top of the roll the Winding operation and which is displaced Vbodily inthe frame oi the machine as the said vroll of Wound material increases in diameter.

,Another object of the invention is to provide improved means for supporting and guiding the top roll in the machine; Vfor counterweighting the roll; and for adjusting the axial relation of the roll with respect to the winding drums which `underlie and support the roll of Wound material.

Still another object of the invention is to provide improved guide means for the Winding shaft, as hereinafter described, together with novel means for adjusting the said shaft to reduce and kcompensate for Wear occurring as a result of the frictional contact of the shaft AWith the guides.

The inventio-n further resides in certain structural mechanical details hereinafter described and illustrated in the attached drawings, in Which:

With reference to the drawings, the machine comprises the usual frame I in Which are journaled the conventional front and rear winding -

drums

2 and 3 which support the work roll 4 of Also supported in the frame for-vertical displacement is a top pressure roll 5 --which acts upon the top of the roll 4, as illustrated. kThe frame also provides a journal support for a -master roll 6 Vfrom :which the Wound material, in the `form in the present instance of :a .paper web1, is drawn. `The roll4 is built up eleof Wound material during view in perspective z .power (not shown).

`upon a winding shait, -this shaft Vbeing heldin vertical' guides 8.9, which are'operatively connected with the-toppressure roll 5, as hereinafter described, and'which are yvertically `movable in the frame I of the machine -With the Vsaid top roll. The web 1 is guided to the Winding shaft 8 by guiderolls II-and -I2 and by the front-Windfing drum 2, as illustrated.

The drums`2 and'3 are driven throughfa shaft I3, which is connectedto a suitable source of The shaft, carries two -pinions I4 and AI5 which vmesh respectively with the projecting

trunnions I8

2 and 3. vThe trunnionl9 of Y bevel gear -2I which meshes With a bevel gear -22 at the lovverend of a vertical shaft 23 journaled in the frame, said shaft having secured rthereto an elongated pulley 24 .which extends to the top of the-machine, as iland I9 of the drums .lustrated Engagingthis pulley is a belt :25, and Athis belt alsoengages apulley 26 secured to a stub shaft 21 journaled,

as lbest-illustrated in-Fig. is slidably supported on frame I. Acorrespond- 2, in a, bracket 28 which a vertical guide 2.9 on the :ing bracket 3l is similarly slidably supported at Ythe opposite side of the machine on a guide 32, and lthese brackets `provide journals 33 for the top pressure roll v5. One -5 carries abevel gear 34 which mesheswith a bevelgear 135- at theilovver end of the shaft 21. In'this manner, a driving ,connection is established between the bevel gear 4,ZI of-the rear winding drumr3 and the top pressure-roll 5. l

As best shown in Figs. tightened on vthe pulleys -an idler pulley or roller 36. This rollerissupvported on one end of a lever 31 which ispivotally Vsecured at ;38to -thebracket"28, and a spring 39 connected tothe opposite end-of the lever exerts the 'lever on its pivot so astoforce the-idler pulley '36 against the belt, thereby-totightenvthe belt,vas in Fig, 4. Secured to `theleveris a pivotedflatch 4|,.thejaw 42 of rWhich is arrangedtoengage afflange 43v on Vthe bracket 28 When the lever is moved about its pivotagainst the pressure ofthe spring 39v sovas to retract the idlerpulley 35from the belt 25; and ya spring 44 connected-tothe latch tends to draw and to retain the latch in an-operative position with respect `to -the said flange. A handle 45 is provided on the endof the lever 31 sothat the 3 and 4,the belt 25 is 24 and 26'by means of lever may be'movedmanually into positionto enthe forward end of the latch 4| to the left, as viewed in Fig. 4, to thereby release the latch and to permit the spring 39 to shift the lever 31 to the belt-tightening position.

Extending upwardly from each of the brackets Z8 and 3| is a sprocket chain, 46 and 41 respectively. These chains pass over

sprockets

48, 48 on a shaft 49 journaled at the top of the frame, and downwardly at the back of the machine to sprockets and 52 journaled in the lower part of the frame. From the sprockets 5| and 52 the chains extend upwardly and are attached to the

respective brackets

28 and 3|. A shaft 53, which carries the sprocket 5|, carries also a sprocket 54, and this sprocket is connected through a chain 55 with a sprocket 56 on a shaft 51 journaled in the frame The shaft 51 carries a hand wheel 59, and is also provided with a ratchet 59 which is engaged by a retractable detent 6|. By turning the hand wheel 58 in a counterclockwise direction, as viewed in Fig. l, the chains 4E and 41 may be actuated to elevate the

brackets

28 and 3|, and with them the top pressure roll 5. For such adjustment, the belty 25 may be loosened on the pulley 24 by actuation of the lever 31, as previously described. It will be noted that the pulley 2B is flanged, so as to retain the belt 25, and that there is also provided on the bracket 28 a guard 62 which partially embraces the belt and the pulley 24, and which is also flanged so as to guide the belt in its normal horizontal position and to prevent its binding on the pulley 24 when the top roll 5 is elevated, as described.

During the winding operation the roll 5 is displaced vertically by the increasing diameter of the roll 4. This elevation of the roll 5 occurs while the belt 25 is tight upon the

pulleys

24 and 26. This upward movement, however, is relatively slow, and the beltl 25 readily adjusts itself on the pulleyV 24 in accordance with the upviard movement of the anged companion pulley 2 i It will be noted that the shaft 49 carries at one end a pulley 63, to which is secured and around which passes a cable 64, the lower end of which carries a counterweight 65. This counterweight is adjusted to counterbalance a portion of the weight of the topvpressure roll assembly. It will be noted also that the ratchet and detent 59-6I, while engaged, permit elevation of the top pressure roll 5 as described above, but prevent a reverse movement, and, therefore, function to releasably retain the roll 5 in the elevated position.

The manner in which the chain 41 is secured to the bracket 3| is illustrated in Fig. 5. Secured to the bracket is a U-shaped element 66, within which is secured, by means of

screws

61, 61, a block 68 to which the chain is attached as shown. The screws 61 pass through slots 69 in the block 68, so that when the said screws are loosened, the element 66 and the bracket 3| to which the said element is attached may be adjusted vertically withrespect to the block and to the chain 41. Such vertical adjustment may be conveniently eifected through the medium of screws 1| and 12 threaded into the top and bottom respectively of the member 66, and bearing respectively against the top and bottom surfaces of the block 68. By means of this adjustment, and the resultant relative adjustment of the journals 33, the top feed roll 5 may be brought into true parallelism with the

drums

2 and 3.

Depending from each of the brackets. 28 and 3| in the manner best illustrated in Fig. 6 is a bar-like extension 13, each of these bars having in its inner face a longitudinal slot 14 which receives the trunnions 15 of the winding shaft 8', and which, therefore, guides the said shaft in its vertical movement. At the bottom of at least one of the slots 14 is a transverse slot 16, througlr which the trunnion may be admitted and withdrawn from the slot. The bars 9, which are rectangular in shape, extend downwardly through a socket 11, which in each instance is secured to the upper end of a rod 18, each of said rods extending slidably through an aperture 19 in the transverse flange 8| of the frame The socket 11 is closely fitted to the bar 13 and acts as a guide for the latter. When the rods 18 are in their lowermost position, as shown in Fig. 3, the sockets 11 rest upon the top of the flange 8|. The bar 13 being free to slide in the socket may now move upwardly or downwardly independently of the rods 18. As the bar 13 moves upwardly in the socket, however, the said socket is eventuallyrengaged by a flange 82 project'ng transversely from the lower end of the bar 13, so that further upward movement of the bar 13 will result in an elevation of the rod 18 in the frame The rod 18 thus assumes the function of a sliding guide for the lower end of the bar 13. By this use of the telescoping elements '13 and 18, the bars 13 may be made suiiciently short so that in the lcwermost position of the top pressure roll 5, the lower ends of the bars 13 will still lie above or at the ilocr level, thereby avoiding the necessity for a pit in the oor for accommodation of the lower end of the guide bar.

In order to reduce to a minimum the wear occurring in the trunnions 15 as a result of frictional contact with the walls of the guide slot .40 '54, and to afford means for compensating for the wear that unavoidably must occur, I prefer to form the shaft 8 as illustrated in Figs. '1, 8 and 9. The body 83 of the shaft is rectangular in form, as illustrated. This rectangular form provides for applying to the shaft a cylindrical core 84, of wood for example, which forms the base for the rollf4, the corners of the rectangular Shaft entering the relatively soft wood of the core, as shown in Fig. 9, and thereby solidly connecting the core with the shaft, while at the same time providing for eventual withdrawal of the shaft axially from the core after the latter has received the wound material, said core remaining in the roll. Within the ends of the hollow 'body 83 of the shaft I insert cylindrical trunnion elements 85 and 86, these elements being provided in each instance with a thrust bearing 81 and radial bearings 98 of the needle type. Each of 'the elements 85 and 86 is provided with a relatively xed collar 89 which separates the bearings 88; and a snap ring 9| is provided in the body to retain the trunnion elements through the medium of the adjoining bearing 88 and the collar 89 in the body member 93. At one end of the shaft and as shown in Fig. 8, the inner race of the thrust bearing 81 is supported on a screw 92 which is threaded into the body 83 of the shaft and which, therefore, is axially adjustable in the latter. This screw may be locked in a given adjusted position in the body 83 by a vset screw 93. The head of the screw 92 is provided with a socket 94 for reception of a wrench 95, which may be inserted through the trunnion element 85, which in this instance is hollow, whereby the screw 92 may be turned for axial Yadjustmentin the'body. V.The outer'race ofthe -thru'st bearing 28'! seats against vtheinner end of the element 85, and this element is vsupported .onxsuitable radial bearings, as described above. This device -therebyprovides for adjustment "of thetrunnion element i85axially ofthe bodyv 83 of the shaft to compensate.' for any wear occurr- -ing atzthe outer ends ofthe trunnions. .Obviousfly both of'ithetrunnion elements may be made uadjustable if desired.

-It-wil-l .beznoted further, see Fig. 6, that the routerfextremities 'l5 of the trunnionvelementsz .and-8.6, which extremities t into theguideslots .14, are made flat at the sides and-are fitted closely between theside walls of fthe slots `so as to beheld against rotation. The body 83 .of the shaft may rotate freely on they anti-friction Vbearings 88; `and by rendering the trunnions non-rotatable, thefrictional'wear with the -guide bar 13 is solely that resulting from the relatively slow s-liding -movements of .the trun- `nions in the guide slots and is thereby held at a minimum.

The elongated pulley and belt drive previously described has a material beneficial effect upon the top pressure .roll action. This is due in part to the free travel of the belt Iaxially of the said ,pulley .and the 4avoidance therebyof resistance to .the normal upward displacementof .the top roll bythe roll .4 of vWound material. This al- .most complete absence of resistance by the .rolldriving means insures uniform displacement at bothends of the toproll, and maintenanceby the top roll of substantially uniform pressure throughout its length upon the roll 4.
