To all whom it may concern:`

Be it known that I, JAMES B. LAWTON, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented .certain new and useful Improvements 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 that class of rollpaper holders and cutters in which the roll of paper is carried and free to turn in suitafrom the roll beneath and severed by a gravitating knife resting on the surface of the roll. Its object is to simplify and improve the construction and operation of such machines, and its novelty will be herein set forth, and specifically pointed out in the claims.

In the accolnpanying drawings, Figure lis 'a frontelevation of a roll-paper holder and cutter embodying my invention. Fig. 2 is a side elevation of the same, with the cutterblade and its supporting-arms in their normal position of rest. Fig. 3 is a corresponding view with the cutter-blade and its arms tilted by the act of severing the paper. Fig. 4 is a detail in section of one of the guides for the supportingarms, showing said arms therein in their normal position of rest. Fig. 5 is a corresponding detail showing the arm in its tilted position. Fig. 6 is a corresponding detail representing a modied form of guide for the supporting-arms, with the latter in their normal position of rest. Fig. 7 is a corresponding detail showing the arm in its tilted position.

The same letters of reference are used to indicate identical parts in all the figures.

A is any suitable base, upon which are secured the upright metal end supports B, connected at their tops by the cross-piece O.

D is the paper roll, suitably and removably journaled in bearings in the supports B.

E is the cutter blade or knife, resting on the upper surface of the roll in front of the supports B, and provided at each end with a hole for the passage of the supportingrods F. These rods, preferably provided with ornamental knobs o, at their upper ends, are passed loosely through the holes in the ends `of the cutter-blade and are carriedin and play through guides G in the supports B.

These guides are inclined, preferably, at an angle 'of from forty to fifty degrees. As shown in Figs. 2 to 5, their upper portions for a short distance conform to the shape of and fit the rods F, allowing the latter a limited tilting play therein, while the under sides `of their lower portions are abruptly beveled through the guides G in a longitudinal direction, to permit the knife to accommodate itself to any irregularities. in the form of. the roll; but when the projecting end of the paper is grasped by the hand and lifted to sever it from the roll, as shown in Fig. 3,7the cutter Eand rods F will be tilted to the position shown in said figure and the rods Willbecome bound in the upper straight portions of their guides G on the points '19, as shown. more clearly in Fig. 5, and will be thereby locked from longitudinal movement, so that the harder the direct upward pull 4on the paper is, the more firmly will the rods be held by the binding-points ZJ of their guides. In this manner, while the rods are normally free to play loosely through their guides, by the simple act of severing the paper in the ordinary way they are automatically locked and the cutter firmly held to the paper, and When the latter has been severed from the roll the cutter and rods fall back to their normal position, so that the roll can be freely turned in pulling forward the paper preparatory to the next operation.

I do not wish to be limited to the exact form of guides shown, it being sufficient if they are so constructed as to bind the supporting-rods therein when the latter are tilted by the act of severing the paper, as above described. For instance, in Figs.` 6 and 7 I have shown the inclined guides G in reversed position, with their straight portions and binding-points h at their lower ends, so that the rods rest in t y their normal posit-ion, as shown in Fig. 6, and.

have produced an exceedingly simple and very efiicient machine, in which the parts may all be made as light as is consistent with the requisite'strength, and yet all springs and auxiliary Weights are dispensed with and the machine operated entirely by the gravity of its necessary parts.

I am aware that roll-paper holders have heretofore been provided With gravitating knives carried by arms sliding up and down in supports in the holder-frames, and I do not therefore Wish to be understood as claiming` such feature; but in these devices as heretofore constructed the knife-supporting arms Were not adapted to tilt appreciably in their supports, so as to cause said arms to bind tightly by a slight pull on the paper, as

with lmy improved device, such slight pull being insufficient to sever the thinnest paper before the arms are caused to bind sufficiently to hold the knife firmly in place.

Having thus fully described my invention, I clairn l. In a paper-roll holder, the combination of the paper roll, its supports provided With vertically-inclined guides made larger at one end than at the other, the cutter-blade resting on the surface of the paper roll, and supporting-rods for said blade inserted through the inclined guides and arranged to move freely therein in the direction of their length, but to be locked therein When tilted by the lifting of the cutter-blade in severing thev paper.

2. In a roll-paper holder and cutter, the combination of the paper roll, its supports provided with inclined guides having bindingpoints, the cutter-blade resting on the surface of the roll, and its supporting-rods passed loosely through and adapted to be tilted in the guides in the supports, whereby upon tilting said rods by the act of severing the paper they become locked in their guides against longitudinal movement, substantially as and for thepurpose described.

3. In a roll-paper holder and cutter, the combination of the paper roll, its supports provided With inclined guides made larger at one end Vthan at the other and having short straight portions at their smaller ends to permit the tilting of the supporting-rods and to form binding-points therefor, the support-ingrods passed loosely through said guides, and

the cutter-blade carried by said rods and rest- Witnesses:
