j Application filed October 22,1901. Serial No. 79,510. model-h istics of simplicity, cheapness, compactness,

efficiency, and convenience in use.

The invention comprises, essentially, a pair of coacting serratin g devices,preferable in the form of rollers, having serrated surfaces, the

rollers being pivoted in a suitable frame or support capable of being manipulated in such manner as to compress the paper between the rollers and by a movement of the latter relative to the former to produce on it is desired to protect.

the paper a band of indentations of any desired length coextensive with the words or figures which it isdesired to protect from alteration.

To accomplish effectually the purposes of the invention, it is desirable that the serrations should be such as to produce a permanent distortion, abrasion, bruising, or straining of the .fibers of the paper which could notloe obliterated by smoothing or other treatment of the indented parts.

The invention may be embodied in many difierent forms. In the simplest form contemplated the inarker-frame consists of a single piece ofspring metal bent upon itself and having the rollers journaled in the respective ends thereof, the axes of the rollers being either parallel with the frame or transverse thereof. In this form the rollers stand normally a slight distance apart, so that the paper can be introduced between them. The user then presses the rollers firmly together and by moving them relative to the paper indents or serrates the portion thereof which The bifurcated frame may consist of rigid arms pivoted af 5o ter the manner ofa pair of shears and may be combined with a spring acting either to bring the rollers together or to separate them. Other modifications of form will suggest themselves to skilled mechanics.

It is obvious that in order to perform properly the desired operation the serrations of one roller must intermesh with those of. the other. would yield sufficiently to furnish the slight lateral displacement necessary for this purpose; but itis preferred to give the rollers a.

slight freedom of'movement axially in their bearings. The points of the serrations of one or both rollers may, if desired, be sufficiently sharp to puncture the paper; but this is notregarded as essential to the end in view. I

The invention includes an inking attachment adjustable with relation to and acting is a side view of a construction differing in detail from that of the other figures.

In Figs. 1, 2, and 3 the frame 1 is formed of a strip of resilient metal bent on itself and having ears 2 integral therewith. The ears have holes 3 and act as bearings for the trunnions l of the rollers 5, said rollers having serrated or otherwise roughened surfaces which indent the paperin contact with which they are pressed. The rollers have slight axial movement in the bearings in order to permit the meshing of the milled surfaces when pressed into contact or against paper inter.- posed between said rollers. On one arm of the frameis a depression 9 for engagement of the thumb of the user. The inking attachment comprises a plate 6, having its ends turned under to embrace the edges of the frame. The plate is slidable on the frame Ordinarily the members of the frame the arms.

and can be moved by means of the thumb of the operator. Arms 7, formed with the under-turned ends of the plate 6, act as bearings for the inking-roll 8, said inking-roll being of any suitable construction to carry ink and having trunnions journaled in the bearings of The serrating-roller acts on the paper on a plane considerably below that of the inking-roll in order that the paper operated upon may not be discolored through contact with said inking-roll.

In the modification shown in Fig. 4 the rollers are mounted on the ends of two arms A, having a pivotal connection B, the extensions beyond the pivot serving as handles. A spring between the extensions tends to press them apart. In using this device the rollers are separated for introduction of the paper by grasping the handles and are brought together to act on the paper by the pressure of spring 10. The instrument would obviously be operative without the spring.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Apaper-markercomprising a frame, and two serrating-rollers mounted thereon adapted to be moved into cooperative rotation by the hand of the user and having pointed teeth adapted to permanently distort the surface of the paper acted on.

2. A paper-marker comprising two arms movable'by the hand of the user, and two ('20- acting serrating-rollers placed opposite each other on the arms and having pointed teeth adapted to permanently distort the surface of the paper acted on.

3. A paper-marker com prising a bifurcated frame, the two arms of which are movable by the hand of the user, and two coacting serrating-rollers journaled one on each arm and having pointed teeth adapted to permanently distort the surface of the paper acted on.

4. In a paper-marker, a frame comprising a strip of metal bent on itself and having ears integral therewith, and paper roughening rollers journaled in the ears.

5. In a paper-marker, afranie comprising a strip of metal bent on itself and having ears integral therewith, rollers journaled in the ears, a plate movable on the frame and an inking-roller carried by the plate.

6. In a paper-marker, a bifurcated springframe, bearings on each end of the frame, and rollers having serrated surfaces, journaled in the bearings.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
