The pivot shaft 38 is rotatably supported in bearings 42 and 43 carried by the side frame members of the machine. The pressure which the riding roller 2| exerts on the roll of material being wound is a function of the resultant moment of the pivot shaft system which is affected by all devices secured to the pivot shaft. In the machine illustrated the resultant moment may be varied by variably locating a bar 44 with respect to the aXis of the pivot shaft. The bar is adjustably supported from the pivot shaft by the arms 45 and 46.

At the beginning of a winding operation the winding shaft I4 is located between the winding rollers 10 and II as illustrated in Fig. l, and is engaged by the leading edge of the web of material to be wound. The riding roller is then lowered and allowed to rest upon the winding shaft .and the winding rollers are then rotated until a roll of material is produced. .So .much of a winding machine haslbeen described'as to pro vide' anunderstanding of the relationship of the present invention thereto. The windin machine is more fully-described in the copending United States Patent applications Serial No. 134,751, filed December 23, l'94'9,'and Serial No. 134,753, filed December 23, 1949, now Patent No. 2,579,791 ofDecember 25, 1951.

.Extendingupwardly from the frames 12 and 13 of "the machine there are provided two vertical standards *41 and 48, 1, which are located,

respectively, opposite each end of the Valley bei tween the winding rollers II] and I l. The standards are spaced apart a distance equal to the lengthof "the'win'ding shaft 14 and provide abutments for preventing longitudinal movement of the shaft.

' .The standards 47 and 48 carry complementary keepers '49 and '50, respectively, as best seen in Figs. '2.and 3, :eachof which has a vertical guiding surface 5| so disposed as to prevent the winding shaft I4 from. moving laterally over the windingrol-ler In during a winding operation. Since the winding rollers '10 and H are driven in the clockwise direction, 2, the roll of material I5 is influenced to move forwardly over the roller 10 owing to'its'reaction. Because of this it is necessary to prevent deviation of the winding shaft from its'upward pathof travel only in one direction.

Each Zkeeper is in the form :of a bar or plate whosefmovements are controlled by cam means such as a series of inclined slots 52 which are engagedby stud :screws "53 fastened to the .front face of "the standardover which the keeper is slidable. The relationship of the slots and stud screws .is such that a keeper will slide to a position'iuwhi'ch it will overlap. and tangentially engageth'eendwof the winding shaft 14 unless it is .restrainedfrom doing .so. When the keeper is lifted'thestud-screws and the slots direct the movement of the keeper away from overlapping relationship'with the end of the windingshaft. Ea'chkeeper'is provided with a lug54by which the keeper may be lifted to effect its withdrawal from overlapping relationship with the end of the winding shaft M. The two keepers are similarly constructedbut are so related to their respectivestandards t! and 48 as to be movable towardsandaway from each other and endwise of :the :shaft 14.

There. are "two similar mechanisms for controlling the positions of the two keepers, one of which includes a lever 55 and the other of which includes a lever 56. It will suffice to describe one of said mechanisms. The lever 56, Figs. 1 and 2, has an arm 51 which is pivotally mounted on a shaft 58 supported by a bearing 59. A finger 60 at the front end of the lever extends to the underside of the lug 54 of the keeper. An arm BI is carried by the shaft 58 and extends rearwardly of the pivot shaft 38. The pivot shaft 38 carries a bracket *52 and an adjustable screw 63 Y which extends downwardly for engaging with the arm 6| when the pivot shaft 38 is rotated clockwise, Fig. 2. The screw 53 constitutes an adjustable stop by which the timing of the initiation of the movement of the lever 56 is determinable. The adjusted position of the screw '63 is such that it will come into contact with the arm 6| and raise the arm 51 and thereby displace the keeper over the front face of its supporting standard and away from overlapping relationship with the --end of the winding shaft when the riding roller 2| has been raised a predetermined distance as shown in Fig. 2.

There is a lever and associated controlling mechanism at each end of the machine for controlling the movements of the two keepers adjacent the opposite ends of the winding shaft. When the pivot shaft is rotated and the riding roller 2| has been elevated "to a predetermined position (Fig. 2),, the two -keepers are lifted and, at the same time, are moved beyond the ends of the'winding shaft l4. With the keepers in these positions the winding shaft and the roll of material accumulated thereon may be rolled over the winding roller l0 and onto the platform 64.

Manual lifting of the roll from the rollers H] and H is rendered unnecessary and saving in time in removing the -roll and in placing a winding shaft for another winding operation is attained by the mechanism of the present invention.

A fresh winding shaft may be readily placed over the rollers I0 and I! while the keepers are held clear'of the facin surfaces of the standards 4'! and 58. Upon lowering the riding roller 2| into contact with the winding shaft, the levers 5'5 and '55 are relieved from support by the screws 63 and the keepers immediately drop and slide edgewise into tangential engagement with the ends of the winding shaft.

The platform 64 is supported by a pair of brackets 65, one at each end of themachine. The brackets have slots 66 which are engaged by studs 61 and 58 and the slots are so shaped as to enable tilting of the platform to different positions. By fastening the platform in a rearwardly tipped position the slitting mechanism 69 comprising a slitting disk 10 is made accessible to an operator. The operation of the machine will be apparent to those skilled in the art in view of the foregoing disclosure.

The principle of the invention, together with mechanism considered to represent the best embodiment of the invention which has been contemplated, has been described, but it is desired that it be understood that the mechanism disclosed is only illustrative and that the invention can @be carried out by other means within the scope of the appended claims. While it is proposed to use the various features and elements in the combinations and relationships"described, some of these may beialtered and others omitted without departing from the invention.
