SPECIFICATION forming part of Letters Patent No. 586,167, dated July 13, 1897.

Application filed March 8, 1897.

To all whom it may concern:

Be it known that I, FRANK H. DUDLEY, a citizen of the United States, residing at Jay, in the county of Franklin and State of Maine, have invented certain new and useful Improvements in Guards for Preventing Rolls of Paper from Slipping on Finders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to improvements in detachable guards for preventing rolls of paper from slipping on the winder during the operation of winding. the core on which the paper is wound is mounted on a shaft adapted to rotate and slide on suitable ways in such position that the paper onthe roll contacts continuously with a rotating shaft which imparts rotation to the shaft 011 which the core is mounted by frictional contact with the paper 011 the core. It is found in actual practice that after the roll gets to be of considerable size it is liable to slip on the core endwise unless it is held bysome device placed against the ends thereof, and inasmuch as the paper itself must contact with the shaft at all times the guard placed against the end of the roll must be of a diameter not greater than the roll itself. It is found in practice that the slipping of the roll on the core doesnot take place until after a considerable size is reached, so that at first the guard need not be used. The custom at the present time is after the roll has been winding for a considerable time to place a wooden disk against the end of the roll and hold it in place by a flexible cord secured to the shaft and allowed to wind around it in contact with the disk. This arrangement is clumsy, difficult of application, liable to fail, and is attended with danger to the operator, because it must be done while the shaft is rotating quickly. To provide a positive-acting guard which may be easily, quickly, and safely applied while the machine is in operation is the purpose of the present invention.

In the drawings herewithinclosed and making a part of this application Figure 1 is a plan View of my improved guard placed in position on the winder. Fig. 2 is a cross-sec- Fig. 3 is a tion taken on line Y Y of Fig. 1.

longitudinal section taken on line X X of Fig. 2, and Fig. i is a View of the clampingtool.

In said drawings, A represents the core-shaft of the winder, its journals being adapted to slide and rotate in bearings B, and O a shaft against which the paper contacts. On the winder-shaft is placed a core-holder D, upon which the core E is supported and over the ends of which the core extends. This holder is provided with a lug F, which projects into a socket Q in the core, or vice versa, the exterior diameter of the core being equal to or greater than that of the body of the coreholder. The external surface of the coreholder is threaded, as seen at G. The paperguard consists of a divided nut E, interiorly threaded, as seen at H, and hinged together, as at I. It is also provided with a pivoted locking-bolt I to lock the two parts together on the core-holder. Secured to the inner face of said nut is a disk J, having a diameter considerably greater than that of the coreholder,

core-holder by being held by a suitable tool upon said core-holder and allowed to turn on by the rotation of the core-holder. The disk has at the point opposite thehinge a V-shaped portion removed, as seen at K, which per mits the opening of the nut on its hinge sufficiently to allow it to be placed over the shaft prior to being placed on the core holder. This is necessary because it has to be put in position after the paper has begun to be wound upon the core and while the core is in rapid rotation, and it will be evident that it could not be placed in position by being put on over the end of the shaft. The nut has a flange L thereon, around which a clamping tool M is placed to hold the nut against rotation while it is being turned on to the I threaded core-holder. The disk maybe of Wood or any suitable material and may be secured to the nut in any convenient manner.

Having thus described my invention and its use, I claim-- 1'. In a device of the character specified, the combination with the windershaft and externally-threaded core-holder mounted thereon, of a divided nut provided with a di vided disk adapted to be brought into engagement with the end of a roll of paper while being Wound upon said core, substantially as and for the purposes set forth.

2. In a device of the character specified, the combination with the Winder-shaft and externally threaded core holder mounted thereon, of a divided nut hinged together at one side and provided with means for locking the two parts together and having on the inner end a guard and on the outer end a flange 10 to receive a tool for holding the guard While being placed in position on the core, substantially as and for the purposes set forth.

In testimony whereof I affix my signature, in presence of two Witnesses, this 1st day of March, 1897.

FRANK H. DUDLEY.
