This invention relates to improvements in winding machines for winding web material on a winding roll which is driven by a surface winding drum and a top pressure or riding roll. The invention relates more especially to `the drive and related mechanism for the top pressure or riding roll. As illustrative of the invention the present embodiment shows a slitting and rewinding machine, and for purposes of simplicity only such features will be shown and described as are necessary or helpful for an understanding of the invention.

As is well known, in machines of this type it is customary at the commencement of the operation for the operator to inch the Winding drum by slipping the clutch, such as a friction clutch, to drive the winding drum at a much less speed than that normally provided. Due to the heat generated under slippage, and centrifugal force exerted, great diliiculty has been experienced in maintaining the clutch in condition to accurately maintain desired tension on the web being wound under variable conditions. Also, the up and down movement of the riding roll due to the accumulation of material on the winding roll and the difference in the counterweights `imposed on :opposite ends of the riding roll exert uneven or unbalanced stresses on the riding roll and its drive.

An object is to provide'an improved mounting means and means for driving the riding roll from the winding drum.

Further objects and advantages of the invention will more fully appear from the following description taken in connection with the accompanying drawings which show, by way of example, the present preferred embodiment of the invention.

Fig. 8 is a somewhat enlarged front elevational view, partly in section, of a portion of the machine on the side opposite the main drive, showing further details of the riding roll drive and mounting; and

Fig. 9 is an end elevation of the mechanism shown in Fig. 8.

Referring to the drawings and more particularly to Figs. 1 and 2; the main frame is cornposed of a base having end frame members I and 2 and suitable tie members such as the bar 3, and a top portion having

end frames

4 and 5 rigidly connected together near their upper ends by a tic piece 6. :Suitably journaled on the base end members I and 2 are a front winding drum 'I and a rear winding drum 8, which jointly serve to support and surface drive a winding roll 9 having a shaft whose ends are slidably supported on respective side frame members 4i and 5 (Fig. 4). The winding drums 'I and 8 have shaft ends extending outwardly beyond the base ends I and carry secured thereto spur gears Il) and II (Fig. 5) engaged by a driving pinion I2 carried on the end of a drive shaft I3 whose inner end is suitably supported in base end I and whose outboard end is supported by a bracket designated in general as I 4. The shaft ends with attached spur gears I0 and I I, and the driving pinion I3 and the adjacent portion ofl shaft I2 are enclosed within an oiltight housing III) provided with a sight oil gauge IIlI'.

M ain drive `Power is delivered from a suitable source (FigsY 4 and 3) by a plurality of V-belts engaging a pulley or sheave I5 which is freely rotatably mounted on the outer end of the drive shaft I3 (Fig. 4). This pulley or sheave carries an inwardly extending drum I6 having a frusto-conical inner periphery forming the driving member of a conical friction clutch. The driven member of the clutch comprises a disc wheel I'I having a hub carried on the inner end of the shaft I3 and rotatably secured thereto by a spline connection permitting free axial movement along said shaft toward and away from the driving clutch drum I6 and normally urged away from said drum by compression springs, such as I8. The friction engaging portion of the driven clutch member comprises a plurality of segments of molded heat resisting friction material, such as the segments I9, which are provided with rewheel i1 serving to hold the segments in align- V ment to provide the friction engaging block assembly having an outer peripheral frustro-conical surface conforming tothe frustro-conical surface of the drum l5; the individual blocks being securely clamped in position by bolts, such as 2i. The driven clutch member is moved into engagement with the driving clutch part by means of a control bearing housing 22, the force being transmitted between the housing and the hub of disc i1 by suitable anti-friction `bearings in a manner well known. The housing 22 is engaged by a control yoke provided on the u pper end of a bell crank 23 suitably (Fig. 3) pivotally supported from a iixed part of the frame and.

whose other end is pivotally connected to the -upper end of a clutch control rod 24 'having a lower end slidably disposed in a lever pin `25 journaled on the outer end of a lever 26 operatively carried on an outboard end o f a torque shaft 21 journaledin the base frame I. The low-1 er extremity of rod 2t is provided with a stop nutrto prevent its disengagement from the pin 25. Actuating force is transmitted from the lever 25 to the rod 24 by means of a compression spring 29 surrounding the lower end of rod Z4 'and dis,- posed between the pin 25 and a pair of adjustable lock nuts 30 threadedly engaged on the rod 24 to provide 'for adjusting the compression in spring 29. It will thus be seen that the actuating force is resiliently exerted through the spring 28. The inboard end of shaft 24 carries rigidly secured thereto (Figs. 7 and 4) a lever arm comprising a pair of spaced bars 28 between which is disposed a lock quadrant 3| which is also mounted on the shaft 21. The quadrant 3| is Vfurther supported and rigidly clamped imposition on the base tie bar 3. The pair of rods k2i! extend forwardly above and beyond the tie-rod 3 and carry pivotally mounted at their free ends a foot treadle 32 supported for angular movement about an axis 33 and'haV/ng a downwardly extending arm pivotally connected at V34 to a treadle lock 'rod` 35 whose rearend is pivotally Connected to a l downwardly extending arm carried on a foot treadle lock 3S provided with a loosing pin 31 whose inner end frctional'ly engages a smooth hardened quadrant surface -3-8 provided on the lock quadrant 3|. It -will therefore be seen that as `the treadle 3-2 is rotated in a clockwise direc-.- tion the lock pin 31 is released from locking en.- gagement with the quadrant surface 38 permitting the control lever to return to its neutral or elevated position; and when the control lever is moved to the lower position to engage the clutch movement ef the treedle .3 2 in an auti-eieeliwise direetieri engages the 'leelspin 31 against the quadrant surfeee .3B positively lodi-ine the meehenism in a position te give .it the desired .degree of engagement between the clutch members.

A suitable housing 4e (Figs. e, 1, 2 and .3) encloses the clutch mechanism .Gemmellng adjacent the driven Clutch Wheel I1 and extending outwardly and over the clutch mechanism, an

opening being provided in the rrear side Kfor the passage of the driving V-belts. The outer periphery of the driven clutch wheel l1 extends upwardly beyond the adjacent end of the housing 40 to provide for manual engagement by the operator to fulll the purpose of the main drive hand wheel, permitting manual adjusting Inovement of the winding drums 1 and 8l The periphery of the wheel Al1 serves es a brak ing surface for engagement by a brake shoe .43!

- 4 (Figs. 3, 4 and 6) pivotally mounted at its rear end to a. xed bracket 42 and pivotally connected at its forward end to a brake rod 43 whose lower end is suitably secured to a brake release lever 44 secured to the outboard end of the shaft 21 (Fig. '7) for movement thereby when the clutch control lever 28 is moved downwardly to drivingly engage the clutch. The brake rod 43 passes through a `compression spring 45 whose upper end engages an adjustable stop nut 45 and whose lower end is anchored on a xed bracket 41. By adjusting the nut 46 the desired braking force may be exerted upon the brake shoe 4i; so that upon release of the clutch engagement the spring 45 will automatically exert braking force against the wheel 41 Vto resist the rotation of the drums 1 and 8. A suitable brake handle 48 is provided on the brake shoe 4| to permit additional manual braking when desired.

Riding roll .Referring mere particularly te Fies- 1 and 2; a

riding roll 5i) is rotatably journaled at one end in a bearing block 5 l slidably mounted on a suitable guideway 52 (Fig. 3) carried on the'upper frame member .4, and its opposite end is suitably rotatably mounted in a journal block 53 (Fig. 8) slidably mounted on a guideway 54 provided on the upper frame member 5 and oppositely'disposed in parallelism with the corresponding guideway .52. The riding roll 53 is supported in a well known manner from sprocket chains 55 andV 56 provided with

variable counterweights

51 and 58, by means of which the pressure exerted by the riding roll on the rewind roll S` may be varied from one end of the roll to the other in .the customary manner to accommodate operating conditions. Conventional means for lifting .the riding roll comprises the hand lift wheel 59 operatively connected for suitable sprocket and chain mechanism designated in general as 60 for exerting lifting movement upon the

chains

55 and 56. Substantial parallelism of the riding roll 5B is provided in a conventional manner by an elevated rack pinion shaft 68 carrying at its opposite ends pinions respectively engaging racks 62-63 provided v on the opposite frame members l and 2. A riding roll tie rail 54 (Fig. l) has one end secured lat (5.5v (Fig. 4) to the slidable journal block 5I Vand its opposite end (Fig. 8) rigidly secured, as by spaced bolts '55, to the slidable journal block 53 for a lateral extent spanning theguide rail 54 and the riding roll driven pinion 10 t0 be more particularly described below. I have found that this provides an efcient means Q f taking the unequal .strain imposed upon the riding roll ,5B due to the unequal pressure exerted onfthc riding roll at its oppositeV ends and the delivery of the driving force at one end of the riding roll only. This provision is important, since it relieves the .stresses which would otherwise be imposed on the journal blocs, guideways and rack and pinion connection, with the attendant friction.

Ridmg Toll drive Referring more particularly to Figs. 8 and '9; a shaft end 61 of the riding roll 5i! is supported in the journal block 53 by means of the ball bearing 68 adjacent to which is disposed an oil seal ring 63. A driven pllQn gear 153 is secured to the end of the shaft end 61' closely adjacent the side frame 5 and is in driving engagement with an intermediate spur `gear 1i secured to a stub shaft 12 journaled in spaced apart ball bearings 'i3- '14, the outer of which is enclosed by an oil seal cap 75. An intermediate bevel gear 19 formed as an integral part of the spur gear ll is in driving engagement with a driven bevel gear Tl fixed on a quill shaft 'I8 which is rotatably journaled in an upper ball bearing 'i9 and a lower ball bearing 8D; the bearings 'I9 and 8i) each being provided with an oil seal ring. The bearings 'i9 and Bil are carried respectively on the upper and lower ends of a housing section 8l which is rigidly securedmto the journal block 53 and therewith provides an oiltight housing for the gear train 'ill-l1, inclusive; an oil sight 8l preferably being pro vided in the housing. The quill sleeve 'F3 is drivingly connected to and freely axially slidable on a spline quill shaft 83 whose upper end extends a suflicient distance to accommodate the full travel of the journal block 53 and whose lower end is provided with a smooth diameter freely rotatably within a driving sleeve dll and supported axially thereby. The sleeve 8d is journaled in an upper ball bearing 85 and a lower ball bearing 86 supported in an oiltight housing designated in general as 8l secured rigidly to the base frame member `2 and provided with a sight oil gauge 87. The sleeve 8i carries secured thereto a driven bevel gear 8.8 in driving engagement with an intermediate bevel gear 89 formed as a part of an intermediate spur gear Si) freely rotatably mounted by means of spaced ball bearings 9.', on a stub shaft 92 which is rigidly bolted to the housing 3l in oiltight relationship therewith. The intermediate spur gear 9@ is in driven engagement with a pinion gear .93 nxed to the outboard shaft end of one of the winding drums, in

the present instance front drum l. For frictionally connecting the driving sleeve Sli with the quill shaft 33 the following more or less conventional clutch means is employed. The lower outwardly extending end of sleeve 8d is rotatably connected to a drive case 94 rotatably connected to a friction drive washer 95. rIhe lower end of the quill shaft 83 is splined as at 96 and carries thereon a pair of friction collars 91 disposed on respectively opposite sides of the friction washer 95. The clutch parts 94-97 are held in assembled position `by means of friction lock wheels 98 threadingly engaged on the lower end of shaft 83 and between which and the lower friction collar 9'! is interposed a compression spring 99.

It will thus be seen that as the winding drum l is rotated the desired driving force is transmitted through the clutch mechanism Sli- 99 to the shaft 83 which is in continuous driving connection with the riding roll 59 during its full limit of travel. It will be noted that the upper gear drive assembly associated with the riding roll 50 is disposed in close proximity to the guideway carrying the journal block 53; and this augments the function of the spanning connection of the tie bar 64 with the journal block 53 in accommodating the stresses involved.

Having thus described my invention with particularity with reference to its presently preferred form, it Will be obvious to those skilled in the art, after understanding my invention, that other changes and modifications may be made therein without departing from the spirit and scope of my invention, and I aim in the appended claims to cover such changes and modifications as are within the scope of the invention.
