This slot construction is old in the art, and permits raising of the roll, and securing of the same in raised position to facilitate threading-through of the paper.

The roll l6 constitutes means frictionally controlled by the paper as it is finger-fed along the plate for controlling means to limit the degree of feed. This limiting means structure per se is not claimed herein, but I believe it new to control such a means alone or with timing means, by the friction action of paper, which is finger-fed across a plate. Referring to Figure 4: There is arranged at the outer side of. the plate I4 and fixed to the roll shaft l! a stop arm 35. A stop slide 36 is suitably slidably arranged in a slot 3! of the plate I4 and this slide is operably connected as at 38 with the stem 39 of a dashpot type of timer, the barrel of which is indicated at 40. The timer per se is not claimed. In order to control the arm and slide for the purposes herein, the same are connected by a link 42 slotted lengthwise at 43. A pivot screw 54 passes through the slot and connects with the arm to form a sliding connection. The opposite end of the link is pivotally connected with a projection 46 of the stop slide 36 whereon it is held by split pin 41.

With the parts positioned as in Figure 5, feeding can be accomplished and during finger feeding the paper, acting frictionally on the roll l6, moves the arm in counter-clockwise direction. After the arm has moved to the right across the top of. the slide to clear it, the link is acted upon to raise the slide to the position shown in Figure 4, thus setting the timer. One complete rotation of the roll, brings the stop arm and stop slide to stop position with the timer set, and released to begin timing. This mechanism per se is not claimed herein.

As long as the slide 36 occupies the position shown in Figure 4, no feeding of the paper can take place because of the frictional relation of the paper with the roll IS. A ratchet wheel 50 and pawl 51 prevent improper rotation of the roll i6. A back-off mechanism is also provided to assure free motion of the slide 36 under control of the timer. This consists of a cam 52 on roll 56, and a roller 53 carried by an arm 54 pivoted as at 55 to the plate M and spring pressed to the position shown to engage the roller 53 with a cam projection 56. After the arm 35 strikes the slide 36 as it does to limit the feed, the roller acting on the projection 56 rotates the roll slightly in clockwise direction to back the lower end of the arm away from the slide 36 to the slightly spaced position shown, whereby downward movement of the plate is not interfered with by any frictional engagement of the arm therewith.

In Figure 6, a modification is shown in which the gravity-acting pinch roll is replaced by a spring-pressed roll 62 acting against roll 60. The roll 62 has a shaft 63 supported in horizontal slots E i respectively carried by the plate HE and the bracket [5. Springs 66 engage the projecting ends of the shafts as shown in Figure '7. In this instance, the paper 28 is brought from the forward side of the roll 27 upwardly between the rolls 653 and E2 and then around roll and downwardly across the rounded upper portion H of the backing plate iii, thence downwardly through the guide formed by backing plate and door.

The feed-limit and timing structures are substantially the same as in the first form, the only difference being that the rotation of the roll 60 for feeding is clockwise rather than counterclockwise. The back-01f mechanism is the same as in the first form, the elements being merely positionally reversed because of the change in direction of rotation of the roll 60 over the roll l6.

Operation In loading the cabinet, the door 2 is swung upwardly to lie on top of the cabinet, and the backing plate swung downwardly to the dotted position shown in Figure 1. The roll of paper is then introduced, and paper is passed upwardly between the rolls, thence downwardly over the upper end of the plate and downwardly through the guide and through the orifice formed by the backing plate and the tear-off knife, to an accessible position, after which the paper is generally torn ofi.

In using the device, the paper may be fingerfed sufiiciently to bring it into View and to a position accessible for grasping, and then the accessible portion may be grasped and pulled to the limit as determined by the stop mechanism; or feeding out of the entire predetermined length may be accomplished by finger feeding. Preferably the user passes his finger or fingers through the slot 4, engages the paper and moves it downwardly as it lies upon the backing plate, to bring a sufiicient length of paper into view for grasping. Then he grasps the paper and pulls it to the limit of feed after which he brings the paper upwardly to the dotted line position of Figure 1 and tears ofi along the toothed edge 6 by an upward-pulling motion. No more paper can now be fed until the slide has moved to its position in Figure 5.

I claim as my invention:
