GUSTAVUS REIN, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE AMERICAN ROLL PAPER COMPANY, OF SAME PLACE.

ROLL-PAPER HOLDER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 449,761, dated April 7, 1891.

Application filed May 16, 1890- Serial No. 352,037- (No model.)

To all whom it may concern:

Be it known that I, GUSTAVUS REIN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Roll-Paper Holders and Cutters, 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 certain improvements in machines for holding and cutting wrapping-paper and the like; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a front elevation illustrative of my invention. Fig. II is a side view. Fig. III is a vertical section taken on line III IV, Fig. II. Fig. IV is a vertical section taken on line III IV, Fig. I, and showing the roll of paper removed. Fig. V is a horizotal section taken on line V V, Fig. IV.

Referring to the drawings, 1 represents a suitable base, and 2 standards secured to the base.

l representsaroll of paper wound, as usual, upon a suitable spindle 3.

5 represents arms pivoted at 6 to the standards 2 and having a knife 7 secured to their upper ends. I

9 represents cross-arms pivoted at 8 to the arms 5 and provided with rollers 10 at their inner ends.

11 represents a cross piece or beam that rests upon the top of the roll of paper and to the lower face of which is secured a cushion or soft bearing-surface 12. To this crosspiece are secured pendants or bars 14:, the connection being made at 13. These bars have slots 15 to receive the journals 6 of the spindle 3, and they preferably fit between the ends of the spindles and the standards 2, as shown. These bars 14 have also extensions 1(5'with inclined backs or cams 17, against which the rollers 10 on the arms 9 bear.

18 represents inwardly-extending projections on the standards 2, against which the bars 9 and 14: bear and by which the bars are held from swinging out of their proper position, these projections holding the inner ends ner ends of the bars 14 from swinging inward or swinging toward the knife of the machine.

The operation of the machine is as follows: A roll of paper is first mounted in the upper notched ends of the standards 2, as shown in Fig. II, the journals of the spindle 3 being first inserted in the slots of the bars 14, so that the bars, with the cross -piece 11, are mounted in the standards with the roll of paper, the cross-piece 11 resting on the roll and the lower ends of the inclined faces 17 of the arms bearing against the rollers 10 (see Fig. III) of the arms 9. The parts are so disposed that when the rollers 10 are bearing against the inclines 17 of the arms the knife 17 is held a short distance from the face of the roll of paper, and as the size of the roll decreases the incline 17 will move the knife 7 inwardly to compensate for the decreased size of the roll. WVhen apiece of paper is desired, its free end is grasped and pulled outwardly, as shown by the arrow A, Fig. III, the crossbar 11 acting as a friction or tension device to prevent the momentum of the roll carrying it around after the pulling-pressure on the end of the paper ceases. WVhen the required amount is pulled out, it is torn off by an upward pressure against the knife, and this upward pressure of the paper on the knife moves the knife toward the body of the roll of paper and causes it to bind against the roll of paper and prevents any danger of the roll being further unwound by the pressure on the end of the paper which is exerted in cutting the paper against the knife, this binding of the knife upon the roll acting as a stop tothe turning of the roll while the paper is being cut. Then when the paper is cut the knife falls back a short distance from the roll again or until the rollers 10 come back against the incline 17, (they having been forced slightly away from the incline by the inward movement of the knife as the paper is being cut off,) leaving the roll to turn freely, so far as the bearing of the knife against the roll is concerned.

I claim as my invention- 1. In a roll-paper holder and cutter, the combination of suitable standards for supporting the roll of paper, a knife, means for supporting the knife, and a vertically-movable block controlling the position of said knife, substantially as and for the purpose set forth.

2. In a roll-paper holder and cutter, the

combination of suitable standards, a knife,

means for supporting the knife, and a vertically-movable block carryingacam, said cam, actuated by the weight of the block, controlling the position of the knife through its supporting mechanism, substantially as and for the purpose set forth.

3. In a roll-paper holder and cutter, the combination of a suitable support for the roll, a knife, pivoted links to which the knife is secured, arms pivoted to the links, a cross-bar resting" on the roll of paper, and slotted pendants sjecured to the crossbar and provided with inclined faces bearing against theinner ends of said arms, substantially as and for the purpose set forth.

4. In a roll-paper holder and cutter, the combination of the pivoted links 5, knife sc cured to the upper ends of the links, bars 9, pivoted to the links and having rollers 10 at their inner ends, pendants 14, a cross-head 11, to which the pendants are secured, and projections 18 on the roll-support, said pendants having slots 15 and inclines 17, substantially as and for the purpose set forth.

GUSTAVUS REIN.

In presence of E. S. KNIGHT, THOS. KNIGHT.
