ROLL-PAPER HOLDER AND CUTTER.

, SPECIFICATION forming part of Letters Patent No. 423,228, dated March 11, 1890.

Application tiled July 19, 1889. Serial No. 318,087. (No model.)

and arranged so as to facilitate the grasping. 'of the severed edge of the paper for arenewed hold, and also to facilitate the tearing of the paper by a pull either upward or downward. l

To this end the'invention consists in combining, with a roll-stand and a brake-bar held upon or against the surface of the roll by gravity or a spring, of an adjustable tearingbar over or under which the free end of the v paper roll passes, held outward automatically by a spring or other force, and adapted to be pushed inward, leaving the end of the paper strip projecting. As preferably constructed, the tearing-bar is duplicated and the paper passes and is guided between, so that the tearing may be effected by a pull against either.

Mechanism embodying my invention is illustrated in the accompanying drawings, in which 'Figure 1 is a perspective elevation of a paper-roll holder and cutter complete embodying my invention; Fig. 2, a detail end view showing the brake-bar guided upon the rollstandards, the tearing-bar guides, the tearing-bars engaged therewith, and the springs; and Fig. 3 is a plan view of a brake-bar and connections.

Referring now to the drawings, A designates the paper roll; B B, the standards in which the same is mounted upon its aXlejournals a a. The standards B B, connected by top and bottom braces h b, constitute the roll-stand entire. C designates a floating or gravity brake-bar resting upon the top of the paper roll and following it downward, maintaining the same relative position as the roll diminishes in size, being held and guided ben tween and upon the parallel standards B B by means of the end projections or lugs c c of the brake-bar. These parts constitute the well-known gravity-bar cutters in common use, and I vhave selected it as a convenient type of machines to illustrate my invention; but itwill be obvious hereinafter that the invention may be applied to brakeebars actuated by springs or arranged in any other manner.

As here illustrated, however, my invention consists in mounting the tearing-bar E upon guides D D, projected forward rigidly from the brake-bar horizontally, or approximately so, near the ends. The bar E is provided at or near its ends with sliding sleeves d, by

4which it is held and moved upon the parallel guide-studs D D. Spiral springs s, placed upon the studs D behind the sleeves d., hold the tearing-bar E normally in its outer position. Centrally upon the top of the bar E, I place a small thumb-piece e, extending upward. If, now, a suitable holding-bar-for example, a wire-is placed beneath and parallel with the bar E, leaving space sufficient for the free passage of the paper, and the lower outer edge of the bar E be formed to an acute angle to constitute a tearing-edge, the device will be operative for tearing the paper upward; but Iprefer to make the lower guide an inverted duplicate E of the tearingbar E, so that the paper may be torn by a pull either up or down.

The action of the device is as follows: In all or nearly all of this type of roll-paper cutters there is no provision for projecting the end of the strip of paper forward under the cutting-bar to retain a renewed hold. In my invention, as will be seen, when the hand is pressed toward the roll in position ready for grasping, the thumb pressing against the thumb-stop e presses back the tearing bar or bars, while the stiffness of the paper causes the end of the strip A to project by simply remaining in its original position, thus enabling the attendant to obtain a firm grip. The thumb-stop e is not essential, and may be omitted, as indicated in Fig. .3.

I claim as my invention and desire to secure by Letters Patent of the United States l. In combination with a roll-paper holder, an adjustable tearing-edge autom atically'held in its outer position for tearing, butg'adapted to. be thrust inward in the act of grasping the end of the paper strip, substantially as set forth.
