11 Claims.

This invention relates to improvements in web roll supports adapted to rotatably carry a roll of paper and permit it to be easily unreeled therefrom.

This apparatus obviates the use of the usual metal shafts or spindles for the support of rolls of paper, ordinarily known as web rolls. Such spindles extend through the web rolls and are heavy and have to be handled manually for movement into and out of the central tube or core of said rolls, therefore causing extra effort, expense and delay.

On the other hand, the mechanism of this invention obviates the above objections and to these ends it is provided with a pair of rotatable cone members, which project slightly into the ends of the fibre or paper core tube, which forms the central. portion of the roll of paper and-on which the paper is wound at the paper mill. These core tubes are generally provided with metal ferrules on their end portions, so as to properly receive the cones above referred to and to prevent deformation of the paper core tube or the paper on account of the great weight of the roll and the shocks due to its handling and rotation.

By reason of the simplicity of its construction and operation, this improved apparatus saves time, labor and expense in the interchange of web rolls and it is, therefore, valuable in these respects.

It is one of the objects of this invention to provide means whereby a rotatable web roll cone. may be quickly and readily engaged with the central tube or core of a new web roll and it also may be speedily and easily withdrawn therefrom when the web roll is exhausted.

It is also the object of this invention to provide mechanism which may be moved quickly to primarily engage and later to promptly disengage the core tube of a web roll.

It is also the object of this invention to provide a supplementary and more powerful slow moving means to produce the final effort of engaging the rotatable supporting cone with the central core or tube in a forcible manner as is necessary to insure its desired fixed centrality and firm contact with the ferrule of the core tube. The same powerful slow moving means are operated in the reverse direction to produce the initial effort of withdrawing the supporting cone, on account'of its firm engagement with the end or ferrule of the central tube or core of the web roll, after which the quick acting means are used to promptly complete the withdrawal.

This permits a new web roll to be speedily, firmly and centrally mounted on a pair of rotatable web supporting cones and when the web is exhausted by unreeling it, the supports can be readily withdrawn and in readiness for again engaging another new web roll.

In cases where the core tubes of the web rolls are substantially of the same lengths and strengths, it is also possible, by means of this invention, to mount them on their supporting cones by the quick movement only, thus conducing to speed of operation.

It is generally better however, to complete the mounting by finally using the slow but powerful longitudinal adjusting means to insure the thorough seating of the supporting cones in the ferrules of the core tubes. A reversal of these 10 operations will withdraw the cones.

It is also an object of the invention to provide a web roll support of generally improved construction, whereby the device is simple, durable and inexpensive in construction, as well as convenient, 15 practical, serviceable and efficient in use.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts, and in the details of construction 20 hereinafter described and claimed, it being understood that various changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

Having thus given a general description of some of the objects of the invention, the two sheets of drawings, attached hereto and forming part hereof will now be referred to as illustrating a preferred embodiment thereof I Figure 1 is a side elevation of a web roll support with the cone in withdrawn position, and also shows a portion of the web roll adjacent thereto;

Figure 2 is a side elevation similar to Figure l, but with the web roll supporting cone projecting 35 partially within the end of the cone in operative position;

Figure 3 is a front elevation and partial section on the line 3 of Figure 2 looking in the direction of the arrow; and

Figure 4 is a vertical axial section, parts appearing in elevation,

Referring now to the characters of reference on the drawings:-

The outer portion of one of the arms of a 45 spider forming part of a reel adapted to carry a plurality of rotatable web rolls and to revolve them successively into operative position, is indicated as H and this is provided with an integral hub I2, which forms the supporting frame 50 for the mechanism of this invention.

Mounted in the bore of the hub I2 is an outer sleeve is, adapted to be moved axially in both directions but restrained from rotation by the feather It. Within the bore of the sleeve I3 is mounted an inner sleeve I5 which is also adapted to be moved axially therein relatively to the outer sleeve is and is restrained from rotation by a feather IS.

The outer sleeve l3 has a slot [.1 in its shell 60 and a rotatable stub shaft |8 has an eccentricaily positioned crank pin or stud l9 adapted to fit in the slot and to reciprocate the sleeve and the parts attached thereto by the rotation of the shaft.

The stub shaft I8 is held in place by an annular washer 20 secured to the hub l2 by tap screws as shown. An operating lever 2| is provided which 7 has its hub mounted on a reduced outer end '22 of the stub shaft 8 and-is secured thereto by a key 23, a bolt 24 and a washer 25.

The operating lever or crank arm 2| has a handle 26 and a spring projected locking pin 2'! which is adapted to be seated in a lower hole 28 to hold-a web roll support cone 4| in operative positiomor in an'upper hole 29 when the support coneis withdrawn and inoperative.

Other holes maybe provided,rin addition to those shown, in order to arrange for different lengths of movement and locking positions of the outer sleeve l3 and its attachments, as will be readily understood. 7

Adjacent to and forming part of the handle is a detent lever 3|, mounted on a pivot 32, adapted to withdraw the locking pin 21 from the hole in which its end may be, while the spring surrounding the locking pin is adapted to project it into either of the holes 28 or 29 or others by operating in the customary manner for such an appliance.

The internal cone supporting sleeve |57 has an internally screw threaded bore 30 adapted to receive the threaded portion of a screw 33 as illustrated. H v

The screw 33 has an intermediate body portion 34 of reduced diameter and surrounding this is a split washer 35 secured tothe sleeve I5 by tap screws as shown, which retains the screw threaded end within the sleeve and limits its movement by contact with its shoulders.

The screw 33 has. a hand wheel 36, secured on its outer end, and this is provided with a hub 31, while a collar 38 is secured to the unthreaded body of the screw, between which and the hub, an annular plate 39 projects, and as this plate is secured to the outer sleeve l3 by tap screws as shown,- the rotations of the hand wheel willslowly but forciblyproject or retract the inner sleeve l5 and the web supporting cone 4| that is rotatably 'to that shown at 2|.

mounted on its outer end.

A web roll supporting cone 4| is mounted on thrust and ball bearings carried by a reduced end 42 of the inner sleeve I5 and is secured in place by a washer 43 and a bolt 44. V This cone 4| is adapted to rotatably carry the web roll 45 which is wound on the core tube 46 which is provided with the usual metal ferrule 4'! adaptedto reinforce itsend in order to protect it against the thrust and expansive force exerted by the cone 4|. 7

It should be understood that the other end of theweb roll,,not shown, has a similar ferrule and a similar mechanism is provided to support it.

The companion cone may be rotatably supported on a solid member which replaces the sleeves l3 and l5 and which is moved longitudinally by a crankpin moved byv an operating lever similar In such case, the hand wheel 36 is not provided on the support forthe end of the roll not shown, as the web roll can haveone of its ends first mounted thereon and the final adjustment and positioning can be ,accomplished at the other end of the web roll by the longitudinally and dually adjustable cone of this invention.

Both cones can howeverybe moved axially and rotatably mounted on'said outer features of the mechanism a brief rsum of its operation will be of interest.

After the core of a depleted roll has been re moved fromthe reel and a co-operative pair of the reel arms are in'non-feeding position, a new web roll is:pla'ce'd between the arms and its core tube ends/are aligned with the cones which are then in retracted position as shown in Figure l.

The handle 26 is then grasped, the locking pin 21 is withdrawn and the handle is then rotated a half turn counterclockwise to the position shown in Figure 2. This produces a quick projecting axial movement of the cone 4|, as, at this time, the

cone is free and easily moved but at the end of this forward movement the cone is in contact with the ferrule 41 of the core tube 46. This half rotation of the handle 26 causes the stud I!) to revolve about the axis of thestub shaft l8 and, as it is connected to the sleeve |3 in the slot H, it will quickly project the sleeve l3 and its attachments, so that the cone 4| the core tube 46. After this is done, the handle is locked in the position shown .in Figure 3 by the locking bolt entering the recess 28. This operation is performed at both ends of the roll, and thereafter the hand wheel 36 may be turned to slowly and more forcibly seat the cone 4| in and against the ferrule 41.:

A considerable length of axial movement of the supporting cone 4| is required,

contacts with the ferrule of 25 owing to the fact that the web rolls are large and heavy and canrolls to be readily and easily placed in readiness l to receive the rotatable supports.

It should also be noted that web rolls vary in length to a certain extent so that some are about'one quarter of an inch or more longer than others and this requires longitudinal adjustment of the supporting cone. V I, 1

In cases, however, where the successive core tubes of the web rolls are substantially of the same lengths and strengths, it is possible to mount such rolls on their supporting cones by the sole motion of projection occasioned by the rotation of the handle 26, which causes the quick forward movement of the sleeve |3 and its attached parts. 7

It may be preferable, however, to complete the contact of the web supporting cone with the end of the core tube by a slight rotation of the hand wheel 36 which compensates for slight differences in the lengths of the web rolls and insures more forcible final pressure, in order to prevent relathe ends of the core tube and this facilitates ease,

speed and economy of operation and conduces to increased output.
