ROLL-PAPER HOLDER AND CUTTER.

SFECIFICATION formingpart of Letters Patent No. 445,116, dated January 20, 1891.

Application filed December 24, 1889. Serial No. 334,817. (No model.)

To aZZ whom, it 12mg concern:

Be it known that I, EDWARD S. KNIGHT, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Roll-Paper Holders and Outters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of rollpaper holders and cutters in which the weight of the roll of paper is utilized to keep the knife in contact with the paper; and my invention consists in features of novelty hereinefter fully described, and pointed out in the claims.

Figure I is a front elevation showing my improved holder and cutter. Fig. II is a top or plan view. Fig. III is a detail section taken on line III III, Fig. I, showing the lower end of one of the levers and the roller-spindle resting in it. Fig. IV is a cross-section of the knife, taken on line IV IV, Fig. II.

Referring to the drawings, 1 represents a base, to which are secured standards 2. 3 represents levers pivoted at 4 to the standards, and whose lower ends 5 form bearings for the spindle (5, (see Fig. III,) that carries the roll of paper 7. The levers 3 curve upwardly'from the pivots 4, and their upper ends ride in a groove 80f a knife 9, that rests on the roll of paper. The knife is notched at its ends, as shown in Fig. II, to receive guides 10 on the standards 2, for the purpose of steadying the knife and keeping it in the proper position. On the upper ends of the standards are projections 11, to prevent the upper ends of the levers from swinging too far out.

The operation of my improved device is as follows: The knife being raised to the top of the holder and the levers being consequently swung outward, the roll of paper is inserted, placing the spindle ends on the ends 5 of the levers. The lower ends of the levers will then be caused to move inward and downward, as shown by the arrows in Fig. I, and the upper ends will move in a similar direction and cause the knife to descend, as shown.

by arrows in Fig. I, as the paper is removed from the roll. It will be seen that as the roll of paper becomes smaller and consequently lighter the ends 5 of the levers move inward (as the points of bearingbetween them and the journals 6 is inside of the pivots 4) and the lighter the roll of paper becomes the greater the leverage on the arms will become, and thus the pressure 011 the knife is practically always the same.

I do not broadly claim the weight of a roll of paper as a medium for keeping the knife against the roll.

I claim as my invention- 1. The combination, in a roll-paper holder and cutter, of a gravitating knife and pivoted levers hearing at one end upon the knife and giving bearing at the other end to the paper roll, substantially as and for the pur- "pose set forth.

2. The combination, in a roll-paper holder and cutter, of suitable standards, a gravitating knife guided by the standards,and levers pivoted to the standards, the lower ends of said levers extending in an inward and upward direction from the pivots and carrying the roll of paper, and the outer ends of said levers extending in an outward and upward and inward direction from the pivots and bearing upon said knife, substantially as and for the purpose set forth.

3. The combination, in a roll-paper holder and cuttter, of suitable standards, a gravitating grooved knife and pivoted levers, the lower ends of said levers receiving and carrying the roll of paper, and the upperends of the levers fitting in the groove of the knife, substantially as and for the purpose set forth.

4. In a roll paper holderand cutter, the combination of the standards provided with guides 10, a grooved knife having notched ends, and levers pivoted to the standards, said levers carrying the roll of paper and bearing upon said knife, substantially as and for the purpose set forth.
