ROLL-PAPER HOLDER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 476,689, dated June '7, 1892.

Application filed August 14, 1891. Serial No. 402,649- (No model.)

To aZZ whmn it may concern.-

Be it known that I, EDWIN E. SENTMAN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Roll -Paper Holder, of which the following is a full, clear, and exact description.

My invent-ion relates to an improvement in roll-paper holders, and has for its object to provide a device of exceedingly simple, durable, and economic construction, and to so construct the device that the knife by means of which the paper is to be severed into lengths will follow the roll downward as the latter decreases in diameter, and whereby also the knife will, through the medium of a roller interposed between it and the roll of paper, exert constant tension upon said paper.

Another object of the invention is to so construct the knife and the tension-roll together that the frame of the device, with the knife and roll, may be carried upward and held in an elevated position to admit of the insertion into the frame of a roll of paper.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figuresand letters of reference indicatecorrespondingparts in both the view s.

Figure 1 is a front elevation of the device, and Fig. 2 is an end view thereof.

The frame of the device consists of two uprights 10, secured to a base 11 or any approved support, the said uprights being connected at their upper ends by a cross-bar 12 or the equivalent thereof. Each upright is provided at its upper end with a longitudinal slot or opening 13, the upper portion of which opening is wider than the lower portion, and this width is obtained by creating a recess in the inner side wall of the slot, forming thereby a shoulder 14, which shoulder is preferably inclined upward. Below the slot 13 a diagonal recess 15 is produced in each upright, in which the trunnions of the reel 16, carrying the paper, are located and are held to turn. Above the paper roll A a knife 17 is located, the urn der surface of which knife is preferably straight and the upper forward portion downwardly inclined to the cutting-edge 18. The knife has attached thereto or integral therewith at each end a downwardly-extendinglug 19, shaped in cross-section to correspond to the cross-section of the narrower portion of the slot 13, in which it is adapted to slide. The lower end of each lug is beveled, as shown at 20 in Fig. 2, and above the beveled surface an elongated slot 21 is formed in each lug. In the slots of the lug the trunnions of atension-roller 22 are journaled, which tensionroller is constantly engaged by a longitudinally-grooved surface 23, produced in the under face of the body portion of the knife. The tension-roller is adapted to rest upon the peripheral surface of the roll of paper and is held constantly in that position by the weight of the knife 17, as the said knife is free to slide in the slots 13, and no device is employed for holding the knife in any one position when the tension-roller is in engagement with the paper roll.

Near the cutting-edge of the knife, in the under face thereof, a longitudinal channel 24 is made, and in the end surfaces of the knife, between its center and cutting-edge, the members of a U-shaped bail 25 are pivoted. Normally the horizontal member of the bail is some distance from the under face of the knife, assuming that position by gravity, and its downward position is limited by stops 26, preferably in the nature of pins located in the knife and engaging with the end or vertical members of the bail, as shown in dotted lines, Fig. 2. This bail is adapted to rest upon the end of paper which is carried from the roll of paper around and over the tension-roller between said roller and the knife and thence beneath the bail.

It is evident that when the bail is dropped by gravity it will force the end of the paper down away from the knife, as shown in Fig. 2, thus enabling it to be readily grasped to out another section, and in cutting a section of paper, the end having been taken hold of and drawn a sufficient distance outward to unreel the desired amount of paper, the paper is then carried upward, so as to engage with the under surface of the, knife, especially at the cutting-edge thereof, and in so taking the paper the bail is made to enter its channel 24. Thus it does not interfere with the proper alignment of the paper, which will, when drawn upward, engage with the cutting-edge of the knife throughout the length thereof. After the paper has been cut the end of that remaining upon the reel will be forced downward away from the knife by the dropping of the bail.

It is evident that as the knife is free to slide in the uprights and the tension-roller is carried by theknifethe knife and rollerwill follow the roll of paper until the last of it has been drawn from the roll, and that the paper may be as readily manipulated when the last portion of it is being taken from the reel as when the roll of paper was first placed in the device.

\Vhen it is desired to replace the roll with another, the knife is carried upward until its lugslflentertheupperwideportionsoftheslots 13 in the uprights, at which time the knife is carried rearward and the inclined surfaces 20 of the lugs of the knife are brought to an engagement and a bearing upon the shoulders H of the uprights.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a roll-paper holder, the combination, with uprights or standards provided with hearings for a reel of paper and slots above the bearings, portions of which slots are wider than others, of a knife held to slide and to fall by gravityin the slots of the standards or uprights, lugs or bearings projected downward from the ends of the knife and containing elongated openings, a tensionroller located beneath the knife the trunnions whereof are journaled in the elongated openings in the bearings, the said lOllSl0l1l'OllGl sustaining the weight of the knife and communicating its weight to the periphery of the paper roll, and a bail pivotally attached to the knife and adapted for engagement with the free end of the paper leading from the reel, as and for the purpose specified.

2. In a roll-paper holder, the combination, with standards having bearings therein and slots above the bearings wider at one point than at others, and a roll of paper the axes of which are held to turn in the bearings of the uprights, of a knife provided with a longitudinal channel near its cutting-edge in its under surface, lugs projected downward from the ends of the knife of a width corresponding to the width of the narrower portions of the upright slots, the knife being adapted to drop and slide in said slots by gravity, atension-roller journaled in the lugs attached to the knife and having vertical movement in its bearings, the said tension-roller sustaining the weight of the knife and communicating said weight to the paper roll, and a bail pivotally connected with the knife, the horizontal member of which bail is located beneath the knife, the said member being adapted to engage with the outer end of the paper leading from the reel and to enter the channel in the knife as thepaper is being cut,substantially as described.
