UNITED STATES PATENT OFFICE.

JOHN REYNOLDS, OF CHICAGO, ILLINOIS.

ROLL-PAPER CUTTER.

SPECIFICATION forming part of Letters Patent No. 434,466, dated August 19, 1890.

Application filed November 30.1889. Serial No. 332,104. (No model.)

.To all whom it may concern.

Beit known that L JoHN REYNOLDS, a citizen of the United States, residing in the city of Chicago, in the county of Cook and State of Illinois, have made certain new and useful Improvements in Paper-Cutters, of which the following is a specification.

Figure l is a plan View. Fig. 2 is an end elevation. Fig. 3 is a perspective View.' Fig. 4 shows details of one of the swinging brackets used, the knob, dog, and ratchet employed. Fig. 5 is a detail of lower roller used with rubberl friction-bands thereon.

`The nature of this invention is to provide a paper-cutter working and constructed as will hereinafter appear.

a is the base and c c are posts resting thereon, as far apart as the paper forming the roll is wide. The roll of paper rests in sockets] in the posts.

b is a cross-beam at top of posts. Y

E E are swinging brackets, loosely attached at one end to the posts c c. rlhere are two of these brackets-one at each post. brackets support the two rollers g and h. The roller g is provided with friction-bands n and lies down against the roll of paper d. Itis slightly larger than the roller h. This roller 7L is above and slightly in advance of the roller g and works in the slots t in the bracket. In front of the roller h and attached to the brackets at each end is the knife k. At one end of roller g and outside ofthe bracket is the knob f and ratchet m, (see Fig. 4,) and against this ratchet is the dog-spring- Z, which, when it engages with the ratchet m, prevents the roll g from turning` one way.

In unwinding the paper from the roll g the end of the paper is passed up Linder the roll g, over it and under the upper roller h, and under the knife 7c, which has an edge on its lower part, and by a sudden movement of the projecting end of the paper upwardly and at an angle with the cutting-edge of the knife the` paper is cut off. By turningr the knob f forwardthe end of the paper is again thrust under and forwardv the knife, ready to be cut These off again. The ratchet m and dog-spring prevent the roll g being turned backward,

which would withdraw the end of the paper 5o the brackets at their respective ends, but are Y loosely attached thereto, so that if one end of the roll of paper d should be larger than the other, or if it should be irregular in shape, the roll g would adjust itself to the surface 4of the roll of paper. The friction-bandsnon roller t, Fig. 5, always insure a speedy movenient of the roll g whenever the knob f is turned.

It will be .observed that there is no spring Ato act against the roll of paper to arrest its movement when a sufficient amount has been unreeled from the roll. This is accomplished by the combined weight of the brackets, rolls, and knife, aided by the special course the paper takes, as shown by thedotted lines in Fig. 2, which is up under, then over the roll g, and under the roll h. friction-roll and the roll his the delivery-roll. The roller g conforms to the inequalities of the surface of the roll of paper d automatically by the force of gravity.

I claim- 1. In a paper-cutter, the combination of the swing-brackets loosely attached to the posts, a friction-roll, a delivery-roll, and a knife, all loosely attached together and capable of al- The roll g is the lowing the friction-roller to automatically adjust itself to the inequalities of the roll of paper,

2. The combinationof the ratchet-spring dog and friction and delivery rollers, substantially as shown.
