UNITED STATES PATENT OFFICE.

JOI-IN H. CORNELISON, 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. 451,809, dated May 5, 1891. Application led June '7, 1890. Serial No. 354,580. (No model.)

To aZZ whom it mag/ concern- Be it known that I, JOHN H. CoENELIsoN, of the city of St. Louis,in the State of Missouri, have invented a certain new and useful Improvement in Roll-Paper `Holders and v Cutters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

.ro My invention relates to certain improvements in roll-paper holders and cutters; and it consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is an elevation of my improved f5 machine. Fig. II is an end view, and Fig.

III represents a modification.

Referring to the drawings, 1 represents a base upon which suitable supporting-standards 2 are secured.

2o 3 4 represent cross-heads on the upper ends of the standards 2, there being a standard at each end of the machine, and each standard having a cross-head 3 at.

5 represents a knife secured to the extremities of the ends 4 of the crcss-heads.

(3 represents levers pivoted at 7 to the extremities of the ends 3 of the cross-heads, and S represents links pivoted at 9 to the upper ends of the levers 6. The lower ends of 3o the links are slotted to receive the journals 1l of the spindle 12, upon which the roll 13 of paper is wound, and the journals rest, as shown in Fig. II, upon the cross-heads 3 4. As the roll of paper decreases in size, it is moved bythe levers 6 and links 8 toward the knife 5; and it will be seen that as these levers and links form toggle-levers and open out toward the position shown in dotted lines in Fig. II the pressure and resistance to the 4o backward movement of the roll increase as the size of the roll decreases, and thus the roll of paper is held against the knife with substantially the same resistance to its backward movement from the time the roll is first put into the machine until the web is entirely removed. The roll may be placed so that the web is severed by an upward movement against the knife, as shown by full ar- A rows in Fig. II, or it may be placed so that 5o the web is removed by a downward drawing of the web across the knife, as shown by dotted arrows in Fig. II; but I prefer the former arrangement, as less friction is incident thereto, the friction between the guide- Ways and journals and the downward pull of the web of paper from the roll both tending to rotate the roll in the same direction.

In the modification shown in Fig. III the links 8 are permanently connected to the levers 6 and the two are secured to the stand- 6o ards 2 at their pivots 9. To the outer ends of the levers t5 are secured the lower ends of links 16, to the upper ends of which akknife 17 is secured, Which is guided by slotted eX- tensions 18 on the ends 4 of the cross-heads. 65 As the size of the roll decreases, the parts move from the position shown in full lines, Fig. III, toward the positionshown in dotted lines, so that with this arrangement I accomplish the same obj eotasin my preferred form 7o that of having a substantially uniform resistance to the backward movement of the roll of paper regardless of the size of the roll.

I claim as my inventionl. In a roll-paper holder' and cutter, the 75 combination of suitable standards having cross-heads supporting the roll of paper, pivoted levers, links secured to the levers and bearing against the journals of the roll of paper, and a knife, the point of bearing be- 8o tween the links and the roll approaching the knife as the size of the roll decreases, substantially as and for the purpose set forth.

2. In a roll-paper holder and cutter, the combination of suitable standards having cross-heads supporting the roll of paper, pivoted levers, links pivoted to the levers and resting against the journals of the roll of paper, and a fixed knife toward which the point of bearing between the links and roll of pa- 9o per approaches as the size of the roll decreases, substantially as set forth.

3. In a roll-paper holder and cutter, the combination of suitable standards provided at top with ysuitable horizontal Ways for the roll-supporting spindle to travel on and a knife with suitable toggle-levers for actuating the roll of paper and keeping it constantly 'pressed against the knife, substantially as set forth.
