HEADFAE3TENING- BEVIGE.

Application. filed March 21, 1928. Serial No. 263,372..

My invention relates to improvements in head fastening devices which are particularly adapted for use in securing wooden heads to opposite ends of rolls of newsprint or other papers intended for shipment in rolls. The present and generally accepted method of applying heads to rolls of newsprint is to secure them to each other by a long and relatively light bolt passing through the core of the roll, but as the heads turn or slide about the ends of the roll during handling, the paper is frequently damaged at its edges, furthermore the threaded ends of the bolts are frequently damaged rendering the removal of the clamping nuts a diflicult task. 1th aview' to overcoming these defects, I have devised means for rigidly connecting the wooden heads to the paper roll in such a manner that the roll can be roughly handled in storing and shipping without becoming detached therefrom or allowing the edges of the paper forming the roll to be injured in any way.

The invention consists essentially of a wooden head abutting the end of a paper core on which the paper is wound and a gripping member set into position by driving a plug into the core, as Wlll be more fully described in the followmg specificatlon and shown in the accompanying drawing m Wh1Cl1Z- Fig. 1 is a general plan view looking down on the head of a paper roll.

Fig. 2 is a detail sectional view showing 13 the head fastening means inserted into the paper core.

Fig. 3 is a detail sectional view showing the fastening means secured in place.

Fig. 4 is a view showing a preferred point to the gripping member.

Fig. 5 is a secional view showing the lower head.

Fig. 6 is a perspective view showlng a gauge used in inserting one of the plugs in a paper roll.

In the drawings like characters of reference indicate corresponding parts in each figure. a

The numeral 1 indicates a tubular core usually formed of laminated paper wound upon a mandrel to a length equal to the width of paper to be shipped, this core is then wrapped with newsprint or other paper to form a roll 2. At a suitable distance from each end of the core 1 a pair of depressions 3 are preferably formed on its inner periphery, which are adapted to receive the dogs 4: of a bale generally indicated by the numeral 5. The bale'5 consists of a piece of strap iron having a base portion 6 and a pair of parallel legs 7 spaced apart to the internal width of the core 1, the outer ends of whichare first inwardly bent as at 8 and then outwardly bent to form the dogs 4;, which dogs are preferably V-shaped in profile and slightly bevelled as at 9, see Figure 5.

Abutting the ends of the paper roll are heads 10A and 1.013, the head 10A being fitted to the top of the roll and the head 1013 to the bottom end thereof The heads are formed generally of two plies of board laid at right angles to each other and nailed together to form circular discs of the same diameter as the finished roll. In the upper head 10A a recess 11 is formed by omitting the central portion of the outer ply of board, the purpose of which will hereinafter appear. Each head is provided with a central aperture 12 equal to the internal diameter of the core.

The numeral 13 indicates a plug which is chamfered about its forward edge as at 14 to substantially conform to the inbent portions 8 of the bale 5. The numeral 15 indicates a wedge of similar width to the plug 18 and of a thickness approximating that of one of the plies of board forming the heads 10. When a roll of paper has been wound upon a core 1 it is set upon its edge and a lug 18 embraced by a bale 5 is inserted into the end of the core. A gauge generally indicated by the numeral 16, consisting preferably of a handle 17 a U-shaped member 18 having a pair of feet 19 and a lip 20 is placed over the end of the plug 13 with its lip the head of the plug. The plug is then driven in by hammer blows directed onto the bale and the head until the feet 19 of the U-shaped member form a contact with the end of the core 1 and the paper roll 2. Subsequent blows upon the plug itself cause the inbent portions of the legs 7 of the bale to be spread apart and the dogs 4 to enter the inner periphery of the core, see Figure 8, to prevent the outward movement of the bale. A head 10 is then put in position on the end of the roll with the base 6 of the bale 5 projecting through the aperture 12, when a wedge is inserted through the gap between the bale and the head and secured in place by a nail 21. The head 10A being provided 20 between the base 6 of the bale 5 and with a recess 11 permits the upper faceof the wedge to lie below the outer surface of the head, but the head 1013 having no corresponding recess causes its wedge to project beyond its outer face, so that the wedge may form a projection upon which the finished roll may be rocked slightly and permit the convenient insertion of the vlip of a hand truck under the edge of the head and the roll when about to move it from one point to another.

What I claim as my invention is:

l. The method of securing an apertured head to a tubular core which consists of fitting a U-shaped bale into the end of said core, of forcing the extremities of the bale outwardly into the inner surface of the core, then fitting the head over the bale and inserting a member between the base of the bale andthe face of the head.

2. A. head fastening device for paper rolls comprising in combination with a tubular core and a head having a central aperture of a diameter equal to that of the interior of the tube, a ll-shaped bale having outwardly turned dogs at its extremities adapted to be entered into the core and having its base projecting beyond the face of the head, means for forcing the dogs into the inner surface of the core, and a member in contact with the face of the head and passing through the U-shaped bale.

3. A head fastening device for paper rolls comprising in combination with a tubular core and a head having a central aperture of a diameter equal to that of the interior of the tube, a plug having a tapered entering end adapted .to be embraced by a U-shaped bale having a portion of its legs inturned to B.
