PAPER-ROLL HOLDER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 335,202, dated February 2, 1836.

Application filed June '26, 1885.

To all whom, it may concern.-

Be it known that 1, CHARLES C. JOHNSON, a citizen of the United States, residing at Springfield, in the county of XVindsor and State of Vermont, have invented new and use ful Improvements in Paper-Roll Holders and Cutters, of which the following is a specification.

This invention relates to improvements in devices for holding rolls of paper and cutting pieces of given length from a strip thereof, the object being to provide an improved apparatus for manipulating a cylindrical roll of paper.

In the drawings forming part of this specification, Figure 1 is a perspective view of a device for holding rolls of paper and cutting off pieces from the paper, embodying my in vention, having one arm of the frame. partly broken away. Fig. 2 illustrates detail parts, hereinafter explained.

In the drawings, A is a suitable base of wood or other material, on which the frame B, hereinafter described, is secured, and which provides convenient means for supporting said frame in proper position in any convenient place for use in holding a roll of paper. A metallic frame, B, has two arms, 0 c, thereon projecting horizontally therefrom. In the arm 0 is pivoted the geared segment d, having thereon the projecting center pin, 6, extending toward the center between said arms, and adjoining the center pin, e, a pin or projection, 0, parallel with the latter. The said center pin, 0, and the pin oserve as means for engaging the segment (Z with the end of a wooden or other cylindrical center piece of a roll of paper, as hereinafter described, the end of the pin e entering a central hole in said center piece, and the end of the pin 0 entering a suitable hole near the center one,whereby the segment and the roll of paper are caused to have a coinciding rotary motion.

A projecting square center piece on the segment (1, in place of the center pin, 6, to enter a square socket in the end of the cylinder f, on which the strip of paper is wound, would answer the same end as the projections e and 0 but .said square socket is less easily formed than two round holes, as aforesaid.

The arm a of frame B is provided with a Serial No. 169,810.

(No model.)

removable center pivot, .2, opposite said projection e, the inner or pointed end of which enters a central hole in the end of the aforesaid cylindrical center piece of the roll of paper, and forms a support for one end of the latter. Said removable pivot 2 has a laterally-projeeting wing, .90, thereon, between which and its head is a slot, or, as shown.

The arm 0 has a perforation through it corresponding in form to the transverse section of the body of the pivot and its wing 00, as shown, and the thickness of arm 0, surround ing said perforation, is equal to the width of the said slot n in the pivot The abovedescribed construction of the pivot z and of the part of arm 0 which receives it provides means for locking the roll ofpaper to the arms of the frame B, and for conveniently removing a center piece from which the paper has been unwound to place a full roll in the frame, as follows: By passing the end of the pivot .2 through the perforation in arm 0, and turning it partly round, the arm is engaged in the slot or in the pivot, preventing the latter from moving endwise from the roll, and by turning the pivot back to its point of starting it is disengaged from the latter. A knife, 10, having preferably a serrated edge, as shown, is attached to suitable arms, on, which have their ends pivotally engaged with the frame B, as shown in Fig. 1,whereby the knife has a vibratory motion between the arms of the frame B. A geared segment, 1 is attached to one of the arms m, which engages with the aforesaid geared segment on the arm a. A rolled strip of paper, h, having said cylindrical or other suitably-shaped center piece, f, having been placed in the frame B, the operation of the device is as follows: The knife and the outerends of the arms at swing downward against the lower part of the base A by gravitation. The end of the strip of paper on the roll it hangs downward from the outer side of the latter. By seizing and pulling the end of the strip of paper the roll 71, together with the segment (1, is rotated, and the engagement ofthe latter with the segment 3 on the knife-arm causes the knife to swing up against the under side of the roll, its edge projecting more or less beyond its periphery. At this point in the operation the paper is drawn downward against the edge of the knife, whereby a piece is cut off, whereupon the knife drops by gravity to its point of starting, and in so doing, through its geared connection with the roll,causes the latter to rotate in a direction contrary to that which was given to it by pulling the end of the paperstrip, as aforesaid, and, to drop the end of the strip on the roll so that it hangs in a pendent position from the latter ready to be seized, as before.

By means of the above-described devices pieces of paper of a given length, or substantially so, may be cut from a rolled strip of paper by proportioning the circumference of the roll to the length required.

It will be seen that when the end of the rolled strip of paper is pulled and the roll is rotated the rotary motion of the latter is imparted to the knife, giving it a vibratory motion, and that when by the separation of the piece of paper from the strip the roll and knife are free the vibratory movement of the knife by gravity is imparted to the roll, causing'the latter to rotate.

What I claim as my invention is 1. In a device for holding a rolled strip of paper and cutting pieces therefrom, a frame, substantially as described, having arms thereon, a roll of paper hung to rotate between said arms, a knife having a pivotal connection between the latter, and mechanism, snbstantially as described, connecting said arms and knife with said roll, whereby by pulling the end of said strip and turning the roll the knife is swung against the roll, and by the re for cutting or tearing pieces from a strip of paper, consisting of a frame having two horizontally-projecting arms thereon, on one of which is pivoted a geared segment having thereon a center to engage with the center piece of a roll of paper, and having on its second arm a removable locking-pivot, substantially as described, to support one end of said roll, combined with a paper cutting knife pivoted to vibrate between said arms, having thereon a geared segment engaging with said first-named segment, substantially as set forth.

4. A roll-holding frame, substantially as described, having arms thereon,between which a roll of paper is pivoted, combined with'a paper-severing knife having a geared connection with said roll, whereby the rotary motion of the roll imparts a vibratory motion to the knife, and vice versa, substantially as set forth.
