3 Claims. (Cl. 93-2) My present invention relates to improvements 2. metal plate It secured to a disk I! of ply wood in roll finishing devices. In most paper mills it or other suitable material, such plate being disis the practice to cover the rolls of paper as they posed so as to cover a circular hole in the disk are delivered from the paper making machines as is shown. On the reverse side of the disk I! with one or more layers of wrapping paper usuis a ring l9 through which pass bolts 28 by means ally waterproofed. When such paper has been of which the plate It is secured to the disk l1.

wrapped around the roll, the ends thereof project Shaft I5 is provided with a screw thread 22 on over the ends of the roll (or have pasted thereon which turns a hand wheel 23 having a hub 24,

portions which do so); such projecting portions the latter preferably being provided with an inmust then be folded down over the end of the terior threaded bushing 25 which may be of 10 roll and secured in place, as for example by plachexagonal shape as shown in Figure 3 so as to ing a disk of larger diameter on the end of the have locking, yet removable, engagement with the roll, then folding and pasting the excess portion hub 24. The wheel 23 is caused to exert presof the disk over on the cylindrical surface of the sure against the plate l6 by means of a sleeve 1;" roll. Or other means may be employed for finor bushing 21 slidable on the shaft l5. l5 ishing the roll. However, in order to facilitate In order to secure the device within the core the securing together of the ends of the paper [3 a clamping device is provided as follows: which have been folded over the end of the roll, Secured to the end of the shaft by means of a it is desirable to employ a clamping device of nut 30 is a fitting 3! in which is pivotally secured some sort which will hold the folded portions by pivots 32 looking dogs 33, such dogs riding in 20 tightly against the end of the roll until the finishgrooves 34 of the fitting as best shown in Figure 4. ing surfaces can be secured in place. Clo-acting with the dogs 33 is a member 35 having It is a principal object of the present invention cam grooves 36 to receive corresponding surfaces to provide such a clamping device which may be of the dogs, the movement of the member 35 readily secured within the hollow spindle of the to the right of Figures 2 and 6 being limited 25 roll and brought home tightly against the surface by a oulde 3 0f the S a t Preferflbly the constituting the end of the roll. engaging portions of the dogs are provided with To this end the invention consists of the novel teeth 38. When the device is not engaged with arrangement of parts about to be described, the the core 38, the dogs are maintained in a refeatures of novelty being pointed out in the aptracted position by means of a circular coil spring 30 pended claims. 43 resting in corresponding notches of the dogs,

The device will be best understood by reference such spring being under tension at all times. In to the following detailed description taken with order to keep the member from rotating, the

the accompanying drawings in which same is provided with preferably four holding 35 Figure 1 shows a roll of paper with my imrods or bolts 42 which are threaded into the 35 proved device in place at each end, end of the cam member and extended parallel Figure 2 is a view on a larger scale through to and surround the shaft I5 passing through the the core of the roll showing a preferred embodiplate Hi. This arrangement permits the plate It ment of my device inserted, parts being in section. to slide freely with respect to the bolts, but such Figure 3 is a view taken along section 3-3 of movement being limited in one direction by 40 Figure 2. means of bolt heads 43. Extending between the Figure 4 is a section along section 3-3 of end of the cam member 35 and the plate It is a Figure 2. tension spring 45 preferably coiled around the Figure 5 is a view along section 5--5 of Figshaft 15. 45 me 2. The operation of my improved device will now 45 Figure 6 is a view similar to Figure 2 showing be apparent. With the wheel 23 in retracted the device in clamped position. position the device is inserted within the core Referring now to Figure 2, a roll of paper 13 preferably as far as it will go (the space between is shown provided with an end covering II, the the plate I! and the end of the roll in Figure 2 portion thereof which extended beyond the roll being exaggerated for sake of clearness) and the having been folded over the roll end, one such locking dogs 33 brought into operative position fold being indicated at l2 Figure 2. The roll l8 by turning up on the hand wheel 23. In so doing has a hollow iron core I 3 into which is to be the disk ll, and consequently the entire clamping inserted the clamping portion of my device. The device, will be held manually against rotation latter comprises a shaft I5 which passes through until the locking dogs 33 start to hold, whereby rotation inward of the wheel 23 will first press the sleeve 21 against the plate 16 after which continued movement of the wheel will cause the shaft 15 to be withdrawn slightly thereby bringing the end 30 of the shaft carrying the dogs 33 toward the cam block 35 and causing the dogs to move upward and grip the interior surface of the core I3, the cam block being prevented from moving more than slightly to the right by means of the spring 45. After the dogs assume a gripping position further rotation inward of the wheel 23 will no longer cause the shaft Hi to move but instead said wheel or rather the bushing 2'! will be drawn tightly against the plate l6 thereby bringing the disk I! tightly against the end of the roll and compressing and clamping the paper wrapper.

The rolls may be finished using my improved device in the following manner:

When the roll of paper is brought to the finishing room it usually has thereon a waterproof wrapper which projects several inches beyond the ends of the roll. It is then usual to place one or two additional wrappers on the roll which may project even further over the ends as for example a total of eight inches. The ends of the wrappers are now broken down over the ends of the roll and one or more roll head wrappers or disks of the diameter of the roll without paste are placed over the ends thereof. Then a roll head wrapper, say eight inches larger in diameter than the roll is placed over said end wrappers. This larger wrapper has its outer circumferential portion cut radially to a depth of four inches, and the serrations thus formed coated with glue. The clamping device is then inserted and the clamping disk I! brought home against the end of the roll. The serrated ends are now turned down and pasted against the cylindrical surface of the roll whereupon a band of gummed kraft tape ll, Fig. 1, is pasted around the circumference of the roll at each end thus sealing the roll head in place. The gum sticks upon contact and the finishing device is then withdrawn.

It will be understood that my improved device while primarily designed for the specific purpose disclosed is useful in any case where it is required to anchor a plate or other object tightly against any surface which is provided with an internal bore. It will also be understood that various changes may be made in the specific construction shown without departing from the spirit of the invention or the scope of the appended claims.

I claim:

1. A device for finishing the paper wrappings on the ends of a hollow cored paper roll, said device comprising a shaft adapted to be inserted within the core, and an expansible clamping unit carried by one end of the shaft for clamping the same within the core, a press plate carried by said shaft and movable thereon, a rotatable hub on the other end of said shaft, means for translating rotation of said hub into core engaging expansion of said clamping unit and means whereby continued rotation of the hub forces the plate against the end of said roll to compress and clamp the end wrappings thereon.

2. A device for finishing the paper wrappings on the ends of a hollow cored paper roll, said device comprising an apertured annular plate and means for forcing the plate against the end of the roll to compress and clamp the end wrappings thereon, said means comprising a shaft passing through the aperture in the plate and adapted to be inserted into the core of the roll, the shaft having means at one end for gripping the core and having means at the other end for forcing the plate against the end of the roll to compress and clamp the end wrappings thereon.

3. A device for finishing the paper wrappings on the ends of a hollow cored paper roll, said device comprising an apertured annular plate and means for forcing the plate against the end of the roll to compress and clamp the end wrappings thereon, said means comprising a shaft transfixing said plate and adapted to be inserted within said core, clamping means carried by one end of said shaft for clamping said shaft within said core, spring means interposed between said clamping means and said plate, and a hub screwed upon the other end of said shaft and engaging one face of said plate whereby said plate may be forced against the end of the roll.
