9 Claims.

My invention relates to means for lifting rolls of paper or other webbing into proper definite position to be engaged by supporting means adapted to permit the paper roll to be rotated by a pulling action upon the web thereof during the withdrawing of the web from the roll.

One of the objects of my invention is to provide manually operated means whereby a heavy roll of paper may be readily lifted and positioned in a machine to which a paper web is to be supplied, the said means having capacity to raise the roll in a vertical direction to any definite height within the range of the apparatus and also horizontally shift the position of the supporting means for the roll in a direction transversely to its axis.

Another object of my invention is to provide means for lifting the paper roll with capacity for adjustment of said means at one or both ends 0 of the roll and longitudinally of the axis thereof and also transversely of said axis whereby the roll may be axially supported and rotated with its ends in definite alinement.

A further object of my invention is to provide means for supporting a roll of paper or other material in a suspended manner with capacity for rotation, associated with means for raising and lowering the roll supporting means.

Another object of my invention is to provide rotatable journals for supporting a roll of paper at an elevation from the floor, associated with lifting platforms arranged beneath the rotatable journals and having means for simultaneously raising and lowering them, the said platforms being spaced apart a distance less than the length of the roll to be lifted whereby a shifting or transportation truck carrying the roll may be moved into position between the platforms so that the ends of the roll are permitted to be 0 positioned above the platforms and'lifted from the truck into position for engagement with the rotatable journals.

Referring to the drawings: Fig. l is a front view of a roll lifting and supporting means;

5 Fig. 2 is a plan view of the same; Fig. 3 is an end view of the same; Fig. 4 is a vertical section through a portion of the same, taken on line 4-4 of Fig. 2; Fig. 5 is an end view of the friction creating means putting a braking action upon the rotating roll of paper; Fig. 6 is a perspective view of one end of one of the mandrels for supporting the paper roll; Fig. 7 is a side view with part in section of the essential parts of a slitting and perforating machine, as an example of the machine with which my improvements may be applied; and Fig. 8 is a perspective View of one of the paper roll plugs axially positioned for receiving the supporting end of the mandrel.

2 and 3 represent two main frames each of so which is secured and supported by the floor so that they are at a definite distance apart, each of said frames being provided with a pair of vertical guide rails l, 4. Sliding upon the said guide rails 4, 4, are carriages 5 having guide rolls 6 engaging said vertical guide rails and are also provided with platforms '7 upon which the ends of the paper roll P may rest, as indicated in Fig. 1. These platforms '7 may furthermore be made slightly depressed or cup-shaped at 7a in Fig. 3. These depressed or cup-shaped portions of the platforms insure the roll of paper taking a definite position upon the said platforms preliminary to itbeing lifted.

The following means are employed for raising and lowering the carriages 5 together with their platforms 7: At the upper end of the main frame 2 is a transverse shaft 12 carrying upon its ends 2 grooved pulleys 11 adapted to be rotated in unison. To the perimeters of each of the said grooved pulleys are respectively secured'the ends oftwo cables 8, the lower ends of which are severally attached at 9 to opposite sides of the carriage 5 through the mediation of adjustable means 9a, such as a turn-buckle. Secured to the same shaft 12 is a further pulley structure 1'? and to the perimeter of this pulley 17 there is secured at 18 the end of a cable 20, said cable extending downward and around an idler pulley 19 arranged near the lower part of the said frame 2. The cable 20 extends horizontally from the idler pulley 19 and is attached to a turn-buckle or adjusting means 21.

Referring now to the other main frame 3, it is provided with a similar arrangement of pulleys 95 and cables for operating the carriage and platform with which it is associated in the following manner. Immediately above the main frame 3 is a transverse shaft 13 suitably journaled and provided at its respective ends with grooved pulleys 11. Connected with each of the said pulleys 11, as indicated at 10, are cables 8 which extend downward and secured to the carriage 5 at 9 where they are provided with turn-buckles 9a. In addition to the grooved pulleys 11, the shaft 13 is provided with a pulley 17 corresponding to the similar pulley on the shaft 12 above the main frame 2. Secured at 18 to said pulley 17 is a cable 20 which passes downward and under an idler pulley l9 and thence extends horizontally to and secured to the turn-buckle 21 aforesaid. The shaft 13 is rotated by a worm and worm wheel gearing 14 which, in turn, is rotated by a spur gearing and pinion mechanism 15, the pinion being manually rotated by ahand wheel 16. It will now be understood. that by rotating the hand wheel 16 in one direction, the carriages 5 and their platforms 7 may be raised and lowered, and it will also be understood that the manually operated means 14, 15 and 16 is caused to operate the lifting means in connection with the main frame 2 because the upper part from said manually operated mechanism is transmitted through the cables 20 to the means for raising and lowering the carriage and turn-buckle associated with said main frame 2. In this manner, both of the carriages 5 are simultaneously raised or lowered, as the case may be.

I will now refer to the means for directly supporting the paper roll and permitting it to rotate, and also for definitely positioning the parts for properly engaging the paper roll and supporting it during its rotation. As similar means is employed in connection with each of the main frames 2 and 3', otherwise than in pointing in opposite directions, the description now to be given will apply to each of the similar de ices. The mandrel 22 (Fig. 4) terminates at one end in a journal head 25 and having a collar 26 secured to it, said collar having a transverse flanged portion 26?) whereby it engages a part 26av of a plug 50 fitted into the end of the paper roll P, and whereby also the unrolling of the web of the paper roll causes the mandrel 22 to be positively rotated. The journal head 25 may be rigid upon the end of the mandrel 22, but ispreferably made adjustable as indicated in Fig. 4, the journal head being positively coupled with the mandrel by a key 28 to cause it to rotate in unison with the mandrel and a screw 27 extends through the journal'head into the end of the mandrel for positioning the said journal head longitudinally of the axis of the mandrel to adjust the distance between the parts 26 at opposite sides of the machine to suit the possible? differences in lengths of rolls to be handled. The mandrel 22 is journaled in roller bearings at 23 within a cylindrical reciprocable" frame 24, said frame 24 being adjustable longitudinally of a box-like frame 37, said frame 37 being adjustable horizontally and transversely of the axis of the'mandrel 22, the said adjustment being made by manual manipulation of the two screws 38a. The reciprocable frame 241s guided within the transversely adjustable frame 3'7 and at the same time being held against rotation therein by being provided with a guide block 29 which is slidable along a longitudinal groove 30 in the frame 3'7, and this'is further assured by a longitudinal rack 31 secured to the reciprocable frame 24 and projecting upwardly into a longitudinal groove 32 on the said frame 37. 33 is a gear secured upon a transverse shaft 34 and caused to rotate with it but permitting slidable motion along said shaft by means of a feather 36 betweenthe gear and its shaft, whereby the gear maintains operative connection with the rack 31 at all times, irrespective of thetransverse adjustment of theframe 3'7 and its associated parts including the rack.

mandrel may be adjusted horizontally and transversely of its axis by adjusting the box-like frame 37 within the main frame 3 by means of the manual operable screws 38a.

It will now be understood that with each of the main frames 2 and 3 provided with the adjustable mandrels, the paper roll may be supported by the journal heads 25 of the mandrels and being rotatable through the said mandrels while the webs are being withdrawn. To prevent spinning of the paper rolls upon their mandrels and to prevent looseness in the web while being fed to the machine in which it is to be perforated and slitted or otherwise treated, a drag or friction may be put upon one of the mandrels 22 and this may be accomplished as indicated in Figs. 4 and 5. Referring to Fig. 4, it will be seen that the left hand end of the mandrel 22 has keyed to it a friction drum 39 and that about this drum is a brake band comprised of the following parts. A stationary section 40 is pivoted at 44 upon a stationary bracket 45 and the under curved surface of said part 40 is provided with a friction band section 49. A spring 42 presses the said portion 40 downward toward the friction drumand the tension of the spring may be adjusted by a screw 43. Curved sections 41 are respectively hinged to the ends of the section 40, as indicated at 41a, and these curved sections 41 are-also provided with brake linings 48 pressing in directcontact with the friction drum. A spring and bolt mechanism 47a-48a is employed to draw the free ends of the braking sections 41 toward each other in more or less tight relation with the brake drum 39 and the tension of the spring may be manually adjusted by the nut 47. As seen, the bolt 48 extends through flanges on theparts 41 and through a lower bracket 46 extending from the reciprocable frame 24. As the mandrels are rotated under the pull of the paper web, the drum 39 at the end of one of the mandrels will be rotated, and this action of being rotated will be more or less resisted by the braking action of the brake band upon the friction drum. This will put a tension on the roll of paper to prevent spinning and the amount ofthis tension upon the paper web may be adjusted as above described.

In the operation of the device, the amount of lift which is necessary to the carriages 5 and the platforms '7 to bring the axis of the paper roll into alinement with the journal heads 25 of the mandrels will depend upon the diameter of the paper rolls and, in the illustration in Fig. 1, it is seen that a very large roll has been placed upon the journal heads of the mandrels and that the total lift of the paper roll from the truck T with which it was brought into position upon the platform 7 is relatively very small. The carriages-5 and their platforms '7 are raised just sufficient to support the paper roll axially of the mandrels. If, on the other hand, the paper roll was relatively half of the diameter shown in Fig. 1, the amount of lift by the carriages 5 and their platforms '7 would be very much greater than the lift required with a roll of the diameter illustrated. The lift may, of course, be to any extent desired or needed to secure the proper elevation of the paper roll to bring it axially into alinement with the mandrels. If, for any reason, the support of the paper roll in its elevated position was such that the mandrels did not enter the plugs of the roll, the screws 38a may be adjusted to horizontally adjust one or both of the mandrels and this same adjustment may be resorted to should the paper web have any tendency to diagonal movement in being unwound.

It will also be noted that in adjusting the paper roll upon the heads of the mandrels, the mandrels are first withdrawn by rotating the hand Wheels 35 and when said mandrel heads are within the casings 2 and 3, the carriages 5 and platforms 7 are lifted to the proper height and thereupon the hand wheels 35 are rotated in opposite directions for causing the mandrel heads to be projected and to enter the apertures 26a in the plugs 50 of the paper rolls. Thereupon the carriages 5 and their platforms 7 are caused to be lowered, leaving the paper rolls to remain suspended upon the mandrels.

It will now be apparent that I have devised a novel and useful construction of apparatus which embodies the features of advantage enumerated as desirable, and While I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details stated as the same are susceptible of modification in various particulars, without departing from the spirit or scope of the invention.
