APPARATUS FOR HOLDING AND ISSUING PAPER FOR TOILET OR OTHER PURPOSES.

SPECIFICATION forming part of Letters Patent No. 495,892, dated April 18, 1893.

Application filed December 15,1891. Serial No. 415,315. (No model.)

Holding and Issuing Paper for Toilet and other Purposes; and I do hereby'declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure 1 shows a perspective view of my apparatus with part of the casing broken away to show the mechanism within; Fig. 2, a rear view of the same with the rear side of the casing removed; Fig, 3,a view of a section on line 90. 0c, of Fig. 2; Fig. 4, a view of a section, on line y. y, of Fig. 2 Fig. 5, a detail perspective view showing the main feed roller with the cutter lifters and the cutter; and Fig. 6 a detail sectional view, showing the operation of the severing striker, in keeping the severed end of the strip down in the groove or depression in the feed roller, until the forward one of the pressure rollers comes to and .projects in over the groove, so that the proper riding of said roller over the stripis insured.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention has been to provide an improved apparatus for holding and issuing, in suitable lengths, paper for toilet and other purposes, and to this end my invention consists in the apparatus and in the parts thereof constructed, arranged, and combined as hereinafter specified.

In the drawings A, A, designate the sides of the casing, which can be of any desired material and construction, and A designates the casing front, which is, preferably, but not necessarily, made of metal, in the shape shown, having the rounded, or semi-cylindrical lower portion, and the upper part covering the top of the casing and extending forward and downward beyond the upper edge of the lower part, so as to leave space between it and such edge, for the issue of the paper to be fed out in the manner to be described.

The casing back A is preferably hinged to one of the sides A, so that it can be opened for the insertion of the roll 13 of paper into the roll receiving lower part of the casing, a look A being provided to normally look the back shut.

WVithin the upper part of the casing, above the paper roll receiving space, is journaled the roller 0, havinga circumference substantially equal to the length of the pieces in which the paper from the roll is tobe issued. As shown in the drawings, this roller, having its shaft provided with a suitable turning head or handle 0, on the outer side of the casing, has in its periphery, the longitudinal depression or groove C Attached to or arranged to turn with the roller, are the disks 0 which I term the lifters, having notches 0 cut in them to correspond in position with the ends of the depression or groove 0 The periphery of each disk is notched, as shown at c, c, the notches 1 having their rear sides with reference to the rotation of the roller made more abrupt than their forward sides for a purpose to be explained hereinafter.

Just above roller 0 are the two other rollers, D. D, which are parallel to each other and rollerC, and are situated apart from each other a distance greater than the width of the groove 0 in the latter roller. Their shafts or pivots d, d, are journaled in slotted bearing openings at, d, on the casing, so that they can be capable of movement to and from the periphery of roller 0. For drawing them normally toward the latter, I provide the spring D, which is U-shaped in general form, having its lower part engaging the under side of an abutment 01 on the inner side of the casing, and its arms hooked at their upper ends to engage the roller shafts or pivots (Z, d, as shown best in Fig. 3. With the described construction, the rollers D, D, will always be pressed toward roller 0, so that any paper passing over the periphery of the latter will be firmly held against the same and caused to travel forward with it as the roller is rotated.

Pivoted or hinged upon the rod E in the upper part of the casing, is the striker F forming the paper cutting device, which extending forward and downward, from its pivotal portion, over the rear roller D and down between it and the front one, hasits lower edge adapted to descend well into the roller groove Oiwhen the latter is brought around under the space between rollers 1), D. Such edge is serrated or provided with teeth f, f, adapted to penetrate a stretched piece of paper easily at points close together. The striker is made wider than the roller is long, so that its sides will project into the notches G in the lifter disks C 0 when it is down in the position shown in Fig. 4, and will be engaged by such disks as the roller is turned forward.

A spring F, having one arm engaging the top of the casing, and the other bearing down upon the upper side of the striker, serves to force the latter downward toward roller C. For convenience sake, the spring is made with its central portion adapted to receive and embrace the striker supporting rod E, a portion of the pivotal part of the striker being removed to accommodate the spring on the rod. In order to allow the said rod with the striker and spring to be easily put in place in or removed from the casing, the supports for the ends of the rod are preferably made as shown, in the shape of open topped sockets into which the ends of the rod, having been forced upward and inward against the stress of spring F, can be easily dropped.

The upper edge of the lower part of the front of the casing is, as shown in Figs. 3 and 4, carried upward and inward, so as to stand close to the periphery of roller 0, and act as a guide for the paper passing downward and outward from such roller.

The operation of my apparatus, constructed as shown and described,-is briefly as follows: A roll of paper of the desired kind is dropped into the receiving space below the rollers, and the free end of the paper is carried upward over roller 0, until the rear one of rollers D, D, engages it, and presses it down upon the first mentioned roller. A forward turn of the latter by means of head or handle 0 will then draw the paper from the roll and carry it forward under the front roller D, and then downward and outward toward and through the issue opening in the front of the casing. With the parts in the positions, shown in full lines in Fig. 4, a piece of the paper has been severed from the roll strip, and the upper end of the latter is held between roller 0 and rear roller D, and the striker F is down with its serrated edge in the groove or depression 0 below the periphery of roller 0. The striker now holds the severed end of the strip folded down into the groove 0 over the rear edge of the latter, and the forward pressure roller D is close to the grooves forward edge. Further rotation of the feed roller causes the lifter disks, at the rear sides of their notches C O, to ride underand force the serrated striker, forming the paper severing device, upward, against the stress of spring F; but the striker edge is not thuslifted clear of the feed roller groove, until the forward roller D has come to project well over said groove, and over the extreme end of the strip, so that the latter could not, as the rising of the striker continues, get up past the underside of the roller. Continued rotation of roller 0 raises the striker clear of the plane of the periphery of such roller, and the forward roller D drops a little into the groove, so as to keep the end of the paper strip bent downward over the groove edge, until the roller rides up over such edge and presses the paper smoothly upon the periphery of the feed roller. The serrated edge of the striker is now held well above the path of the paper, readyfor another severing stroke, when the notches in the lifter disks are again brought around to the part of the striker resting upon said disks. From the drawings, it will be seen that the forward one of the two rollers D D is situated close to the path of the strip severing striker-and so that it will be close to the forward edge of the groove or depression in the feed roller, when the severing operation takes place. With this construction said roller D will, immediately after such severing, be brought, by the rotation of the feed roller, so as to project inward over a part of the groove in the feed roller, before the severed end of the strip, which has been carried down into said groove, is released by the striker, and left free to rise again (see Fig. 6). This insures the proper riding of the forward pressure roller over the strip end, so that said roller will engage the strip where it is bent down over the rear edge of the feed roller groove, and prevents any chance of the paper getting curled up or wrinkling, because of its edge abutting against the rear side of the said pressure roller. The device for raising the severing striker is arranged so as not; to raise the lower edge of the latter clear of the groove, until the forward pressure roller has, because of the rotation of the feed roller 0, come to project well over the path of the severed strip edge as the latter tends to fly up. Meanwhile, the already severed sheet, whose rear edge is held between the front roller D and roller 0, is fed down and out of the casing, and, as the latter roller continues to turn the edge of the strip running from the roll, is carried forward to and under said front roller D, and from the latter down toward the delivery or issue opening. During the said turning of roller 0, the strikerFbearingupon the edges of the lifters C C rides over the serrations therein, and, by engaging them, prevents any backward revolution of the said roller. As the latter is turned to bring the groove or depression 0 around to the space between rollers D, D, again, the notches 0, C in the lifters C C allow the cutting striker to be driven down quickly by the action of spring D, so that its serrated edge will strike and easily sever the in the number of notches C in the lifter disks C 0 pieces of the same length could be caused to be delivered byonly part revolutions of the main roller.

Instead of making the spring and striker separate, both can be combined in one piece by making the upper part of the latter of spring material and attaching it to some suitable support.

It will be noticed that in my apparatus no supporting shaft is necessary to receive the roll of paper placed in the receptacle below the feeding rollers. Of course, one can be used if desired, but it is not at all necessary.

My apparatus, as shown and described is simple and cheap in construction, and, while being efficient and certain in action,contaius no parts or mechanism capable of getting out of place, or out of order.

Having thus described my invention, what I claim is 1. In an apparatus for holding and issuing paper, for toilet and other purposes, having a suitable receptacle for the paper strip, in combination with the feed roller having a longitudinal groove or depression in its periphery the strip severing striker striking down into the roller groove, so as to entirely sever the strip stretched across the same, and two rollers, to press the strip against the feed roller periphery, situated, respectively, in front of and to the rear of the path of the striker, the forward one of such pressure rollers being close to the point where the striker divides the paper, so that the severed end of the strip cannot get up past it, but must pass under it, as the feed roller is turned forward, substantially as and for the purpose specified.

2. In an apparatus for holdingand issuing paper, for toilet or other purposes, having a suitable receptacle for the paper strip, in co D1- bination with a feed roller having the longitudinal groove in its periphery, the strip severing striker striking down into said groove close to the forward edge of the same the two movable pressure rollers, situated respectively, to the front and rear of the path of the striker, the forward one of such rollers being placed so as to be close to the forward edge of the feed roller groove when the striker descends into the latter and spring means forcing the pressure rollers toward the feed roller periphery, substantially as and for the purpose described. 7

3. In an apparatus for holding and issuing paper, for toilet and other purposes, having a suitable receptacle'for the paper strip, in combination with a strip severing striker the rotary roller for feeding the strip forward having a depression or groove in its periphery, the two pressure rollers having their shafts journaled in bearings to allow them to move toward and from the feed roller and the U- shaped springs each engaging a suitable stationary abutment and having its two arms engaging the shafts of the two pressure rollers so as to draw them toward the feed roller, substantially as and for the purpose set forth.

at. In an apparatus for holding and issuing paper, for toilet and other purposes, havinga suitable receptacle for the paper strip, in combination with the feed roller, with a longitudinal groove in its periphery, the strip severing striker, adapted to strike through the strip down into the feed roller groove, pivoted to swing downward and rearward toward the rear side of such groove, so as to fold the severed strip end down over the groove edge, and the two pressure rollers to'the front and rear of the path of the striker, the forward one being situated close to said path, substantially as and for the purpose shown.

5. In an apparatus for holding and issuing paper, for toilet and other purposes, having a suitable receptacle for the paper strip, in combination with the feed roller having a longitudinal groove in its periphery, a strip severing striker, automatic means, operated by the feed roller, to raise the striker and release it, as the roller groove is brought around to its path, one or more pressure devices forcing the striker down toward the roller and the two pressure rollers respectively in front and to the rear of path of the striker, the front roller being situated so as to be close to the forward edge of they feed roller groove, as the striker descends to sever the strip, substantially as and for the purpose shown and described.

6. In an apparatus for holding and issuing paper, for toilet and other purposes, having a suitable receptacle for the paper strip, in combination with the feed roller having a longitudinal groove in its periphery, a strip severing striker to descend into such groove, the two pressure rollers respectively to the front and rear of the path of the striker, and means for causing the latter to descend into the groove and rise again, as the feed roller rotates, adapted to allow the striker to remain down in the groove, until the forward pressure roller is brought partly over the groove, by the rotation of the feed roller, substantially as and for the purpose specified.

7. In combination with the rotary feeding roller having a depression or groove in its periphery and the spring actuated strip severing striker, one or more striker lifting disks turning with the roller, each having a notch, to allow the striker to descend into the roller groove or depression, and a series of smaller notches, in its periphery to be engaged by the striker, so as to prevent backward turning of the roller, substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set myhand this 8th day of December, A. D. 1891.
