XMy invention relates to means for supporting a roll of paper stock in feeding position directly.

in front of a machine for producing paper goods from a web, suchas envelopes, cartons, egg case 5 fillers and trays', various kinds of* containers, laminated and corrugated boxboard, etc., andL-as modern production machines of `this type run at high speed, it is very important that the rolls of paper stock for same may be easily and quickly u, mounted in perfect alignment with the feed mechanism .of themachineand arranged to unwind easily and steadily as the machine draws the paper from the roll. I

As it is common practice in the paper goods i5 industry to use paperstock in rolls as large as 4five feet indiameter rand weighing about 600 pounds each, it is a considerable task to replace the exhausted rolls atrpfrequent intervals, andas the machine must be at a stand-idle during such :bfi intervals, it is very important to replace such rolls in the shortest possible period of time.

It ,is therefore an object of my invention to such rolls of paper stockavith the least possible '-5 effort on thepart of the operator, so as to promote ecient Iand economical operation o f thel fabricating machine. l

A further object of my invention is to provide aramid-change reeldevicefwhereon the operator Il may mount and prepare ia second roll on an auxiliary arbor during the period While the rst rollv is being fed through the machine and while the operator is not otherwise employed, so that the prepared roll may be simply swung into feeding 115 position and connected lwiththe feeding mechanism of the machine in considerably less time `than would otherwise be required.

My invention consists in providing identical roll supporting arbors at opposite ends of a support-V i.) ing frame mounted for rotary adjustment, Vso

that while one roll is being fed to the machine from an arbor at one end of the frame, a secondy rolllmay be adjusted on the other arbor and mounted on the frame at the other end thereof, if and as the frame is mounted on anti-friction bearings, it is adapted to be easily and quickly rotated in a'horizontal plane to a point where the second roll will replace the exhausted roll, and the frame may then be locked in such ad- .'U iustedY position while a third'roll is prepared for the next change; Other objects of the invention will appear from the. `following description and accompanying drawings and will be pointed out Vin theannexed :'3 claims. f

provide 'an improved means for rapidly-replacing In the accompanying drawings there has been disclosed Va structure designed rto'carry out the various objects of the invention, but it is to bey understood that the invention is not confined to the exact features shown as various changes may 5: be made within the scope of the claims which follow. A .o i

Figure '7 is asimilar View showing the .means 30 for supporting theopposite end of the arbor. o

In the drawings, numeral I0 indicates'a circular base casting which may be securedto. the .A floor by bolts II passing through holes yin recessed'flanges I2 at four points on the vperiphery 35I thereof. A'vertical standard I3y is bolted-to the center of this base and is providedjwith -an rextension I4 having anl adjustable collar I5 vat its upper end. -A bearing ring I6 encircles the lower end of the standard I3 and is provided with ratm circular groove for receiving suitable bearing elements or balls I1, which support a bearing ring I8 on which a horizontal plate I9 is mounted. The plate rI 9,'.as here shown, is squarein outline, and`has arranged thereon a pair of side 45fframe members 20which are shown bolted to op.-` posite'fside ledges thereof. .The upright frame members 2|] are connected together at their upper endsby a cross-member 2|, Whichhas a central bearing 22 wherein the extension lI4 is 50` journaled.' The plate i9, side frame members 20, and cross member 2l cooperate to providea supporting frame for the paper rolls, as will subsequently be described.

The crossmember 2l has bearings Y23lad`jac`entv 65 its ends which rotatably support the upper ends of a pair of shafts 24. Hand wheels are secured to the upper ends of the shafts 24, and collars 26, secured to the shafts beneath the bearings 23. prevent upward movement of the shafts. Plugs 21 have threaded connections with the lower ends of the shafts 24, and these plugs have tapered lower ends adapted to enter a similarly tapered hole provided in a hardened bushing 28, inserted in the base I0 directly beneath one of the shafts 24, when the supporting frame is inV`v one of its adjusted positions, as shown, for example. in Figure 3. Said plugs have vertical grooves 29 adapted to receive the shaped ends of screws 30 which prevent the plugs fromrelatively rotating in their fixed sleeves 3|, throughk the walls of which said screws extend into said grooves.

When the hand wheel 251, positioned over the bushing 28. is turned in one direction, said shaft 24 will force the tapered end of its plug 21 into the tapered hole in the bushing 28, whereby the supporting frame is locked in adjusted position on the base I0. When the hand wheel ,is rotated in the opposite direction, itsy complemental plug 21 is withdrawn from the bushing 3l, whereby the supporting frame may be freely rotated .upon` its base l0 to present a fresh roll of paper to the fabricating machine. e, o The opposite ends of the side frame members 20 extend outwardly beyond the plate'IS and terminate in curved projections 20', each having a smooth top surface. Openjbearings 32 are pro# vided in the upper faces of the projection 20', and are spaced inwardly from the terminals thereof. as best shown in Figures 1 and 2. The bearings 32 are adapted to receive the arbor shafts 33. as shown in Figures 1 and 2.

Suitable latch arms 34 arehinged at oneend to the frame members 20 adjacent to the open bearings 32. The opposite ends of these latch arms are provided with thumb screws 35 adapted to enter threaded holes 36 in the projections 20',

. thereby to lock said arms'inplace withtheir tions ,33 ,of sufficient length to allow curved intermediate portions extending over theV arbor shafts 33, to keep said shafts in theirrespective bearings 32, as shown in Figure 2. In operation, I have found that the Weight of the arbors 33 with the paperrolls mounted thereon, will keep the arbors in the bearings 32, and the latch arms 34 may therefore, be dispensed with in-some instances, if desired. 'I'he arbor shafts 33 are shown provided with reduced end porsaid shafts to slide endwise in the bearings 32.

A brake drum 31 is secured at one end of each shaft 33 in position to be engaged by av brake shoe 3,8 which has a threaded hub at one end mounted on a short threaded shaft 39. 'I'he opposite end of each brake shoe 38 is provided with an eye-bolt 40, having a hand wheel or nut 40 received in threaded engagement therewith. Another brake shoe 4| is hinged to the brake shoe 38v at one end, while its other end is slotted to receive the eye-bolt 40,'andwhereby the brake shoesmay be lightly clamped on the brake drums 31 to apply frictional resistance against rotation of the arbor shafts. their inner ends journaled in bosses provided on the frame members 20. 'I'he outer ends of these shafts are journaled in bearings 42 provided in suitablev brackets 4 3, shown bolted to diagonally opposite ends of Hand wheels 39' the side frame members 29. are secured to the outer ends of the shafts 39 whereby said shafts may be rotatto keep said cone from The threaded shafts 39 have fabricating machine.

ed to axially translate the brake shoes thereon. Such axial movement of either pair of brake shoes 38 and 4l, brake drum 31, as shown in Figures 1 and 2, vwill cause the arbor shaft of said brake drum to be longitudinally moved in the bearings 32, as a. result of the vbrake shoes engaging thefianges 31 ofthe drum. u "l Each arbor shaft is provided with a screw threaded portion 44 on which the threaded hub of a hand wheel 45 is disposed with its hub in contact with the hub of a ianged` cone 46 in which a key 41 is secured, which is slidably rcceived. in a key-way'48 in said shaft, thereby turning thereon. Another flanged cone 49 is loosely arranged on the shaft 33 and is held in a predetermined position thereon'by a dog 50 which is pivoted at one end to the cone 49, in position to enter a transverse slotl in the hub of said cone and an annular groove 5| in the arbor. Ay roll o f paperstock 52 ,may be held firmly in i tween the flanges of the'cones 46 and 49 at each end of the rotatably mounted supporting frame,v as shown in' Figures 1 and 2;

4In' the operation of the novel apparatus herein disclosed, a :roll of'paper 52 ismounted on an arbor at one end of the machine, andthe end of the paperfweb is then fedinto the paper feeding mechanism of the fabricatingmachine (not shown), as indicatediby'the'arrow'at the left' hand side of Figure 2. `After the fabricating maf, an operator or attendantchine has been started, may mount another roll 53 uponthe opposite end of the supporting framejas shown in Figure 2. When the roll of paper 52 has been fed into the fabricating machine or is exhausted, the ophand wheel 25`in a directionA As the fresh roll'ofpaper is being uriwoundbyv the fabricating machine, the operator insertsan empty arbor, shown inK Figure 4, through the core of afresh roll of paper. complished by removing the This is readily ac cone 43 from the yempty arbor, and inserting the arbor"tlrogh` the usual opening provided'in the core o1' the'roll ofpaper, aftery which the cone 4 9 is secured to the arbor and the roll securely clamped in position on the arbor by manipulation of the hand wheel 45.I

f 'I'he fresh roll of therein, lis then rolled up'an inclined block 54, which is arranged in" frontof the supporting place` on the arbor shafts bef` The end of the fresh roll of paper with an arbor mounted when engaged with their respective frame and is of such height that the ends oftheY arbor vshaft will pass over the terminals of the end portions 2 0' of the side frame members of the supporting frame, Further forward movement of the roll will cause the bearing portion's33 of the arbor to enter theV open bearings 33 of the supporting frame, after which the arbor may be secured'in position therein by manipulation of the latch arms 34.

Itis essential that the `roll of paper .be Y accu-V rately alinedwith the paper receiving end'of ther `This is readily accomplished by manipulation of the hand Wheels 39',

whereby the arbor may be axially moved in the frame to laterally adjust the fresh roll of paper with respect to the receiving end of the fabricating machine.

By the use of this novel structure, the operation of supplying a fresh roll of paper to the fabricating machine is greatly expedited, which results in greater economy and output of the fabricating machine. If desired, three arbors 3 mayv Athe arbors mounted in the machine are provided with independent means for longitudinally ad.

justing them, and also with means for frictionally controlling the rotation of the rolls. In like manner, duplicate locking means are provided on the supporting' frame for locking the supporting frame in adjusted position upon the base l0, whereby an operator may readily and conveniently manipulate the machine in the operation of rotating it from one position to another, as indicated by the arrows in Figure 1, by standing at one side thereof.

In the drawings, I have shown the supporting frame mounted on spherical bearing elements l1, but it is to be understood that' other forms of bearings, applicable for the purpose, may be' utilized without departing from the scope of the invention. It is also to be understood, that While I have shown but one locking bushing 28 in the base l0, two such bushings may be used, one on each side of the base, whereby the operator or attendant may be stationed at 'either side of the machine.

I claim as my invention:
