SPEGIFIQATION forming part of Letters Patent No. 744,140, dated November 17, 1903.

Application filed March 31,- 1903. Serial No. 150,394. (No model.)

To all whom, it may concern:

Be it known that LJAMES S. WEMYss, a cititen of the United States, and a resident of moving waste paper from cylindrical cores.

In the process of printing newspapers upon cylinder-presses the large rolls of blank paper are primarily placed upon cylindrical cores composed of metal, and these cores are adapted for reuse; but the full quantity of paper on the core is not consumed by the press, a portion of paper always remaining on the core after the major part thereof has been used up for newspapers. This surplusage must be removed from the core before the same can be resuppliedwith a fresh roll of paper.

It is the object of my invention to provide an efficient. means whereby the surplusage, embodying a single strip of paper, may be rapidly removed from the core in a cleanly manner and converted into a plurality of superposed sheets, which may be utilized for various purposes.

The invention will be hereinafter fully described, and specifically set forth in the annexed claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of my improved machine, shown partlyin sectional elevation; and Fig. 2 is a vertical sectional elevation taken on the line so a: of Fig. 1 looking in the direction of the arrow y.

In the practice of my invention I provide, primarily, a supporting-frame embodying end uprights A each mounted upon a suitable base-block A and having braces and a connecting horizontal beam A to supply rigidity to the structure. This in the drawings is shown as a wooden framework; but itis obvious that a metallic structure of any suitable design may be employed. Extending horizontally between the two uprights near the top of the frame and rigidly secured thereto by means of metallic bearings 1 andscrews 2 v is a rod B, having two longitudinally-adjustable hangers C mounted thereon, which are -held in arbitrarily-selected position on the rod B by means of thumb-screws 0. Each hanger (J-has an inwardly-extended pin 0 upon its lower end which carries a revoluble metallic cone D for engagement with the cylindrical cores, as will be hereinafter described.

Extended across the machine parallel with the rod B and considerably below the same is a revoluble shaft E, which is journaled at each end within boxes 3 and carries a fixed reel F, which embodies the end heads F, centrally-located part F and longitudinal strips G. These strips G are arranged in pairs, whereby a continuous groove 9 is formed between each pair, and the heads F and central part F are each provided with radially-extended slots f, which register with these grooves whereby when the reel is supplied with a roll of paper the same may be 1 out into a plurality of superposed sheets by running a knife from end to end through oneof the grooves g.

As a means for turning the reel F, I may employ either apulley, as 4, which may be attached by a belt to a driving-pulley, or a hand-crank, as 5.

In the operation and use of the apparatus one hanger C is loosened and moved toa sufficient distance to admit of placing a cylindrical core 6 on the two oppositely-located and parallel cones D, which are jammed within the cylinder to take secure hold thereof. Then said hanger is secured by means of its thumb-screw c. The free end 7 of the roll of paper is placed within one of the grooves g of the reel, and said reel is given continuous rotary motion until all the paper is transferred from the core 6. Another partly-filled core is then substituted and the operation repeated until the reel is supplied with a sufticient quantity of paper, when the same is converted into a plurality of superposed sheets by passing a'knife from end to end across the roll on the reel and through one of the grooves g.

The longitudinally-adjustable hangers 0 admit of employing the machine in connection with cores of various length, and the elongated reel is adapted to receive strips of paper of any desirable Width.

Having now described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a machine for unwinding paper from cores, the combination with the adjustable hangers and the revoluble cones thereon and means for supporting said hangers, of the reel and supporting-framework, and means for revolving the reel, substantially as shown and described.

2. In a machine for removing paper from cylindrical. cores, the combination with the adjustable hangers having the revoluble cones, and means supporting the hangers and for adjustably fastening them, of the elongated reel having longitudinal peripheral grooves, and means forsupporting the struc- JAMES S.
