9 Claims.
This invention relates to improvements in sheet dispensing apparatus, the present embodiment being particularly adapted for dispensing paper toweling.
The present invention is generally related to a type of device shown in my co-pending application No. 99,584 for Toweling dispensing apparatus, and one object of the invention is to provide an improved stop mechanism which is controlled by a swinging paper feeding device against which the paper is frictionally held by the nger while being swung to feed the paper. The friction-held paper is thus entrained or pulled to accessible and visible position when the swinging element is moved in feeding direction. Another object is to provide a feeding device in which feeding can be obtained by repeated operations of the swinging element, or in which the paper can be brought to accessible and visible position by a single operation of said element, to be thereafter grasped by the hand and be fed or pulled out independently of said swinging element.
Features of the invention include all details of construction in relation to the above objects and to the stop mechanism and control thereof, along with the broader idea of means inherent in the disclosure.
Objects, features and advantages will appear in the description of the drawings, and in said drawings,
Figure 1 is a vertical section in part on line l-I of Figure 3, with the stop mechanism in stop position;
Figure 2 is a vertical section similar to Figure l, showing the stop mechanism in non-stop position and as when the nger feeding device is at the end of the feeding stroke;
Figure 3 is a plan section taken approximately on line 3 3 of Figure l; and
Figure 4 is a detailed vertical section taken approximately on line 4-4 of Figure 1.
Numeral l generally indicates a casing having a back 2, a bottom 3, sides 4 and 5, and a hinged closure 5 which constitutes the front and top of the casing and which is hinged to the bottom 3 by a suitable pintle 1. The rear end of the top portion 8 of this closure 6 engages with a rolled bead l (see Figures l and 2) and a top portion f8 has a lock H the tumbler of which engages a slot not shown of the bead.
The front portion I6 of the closure is provided with an opening l1 through which the ringer of the user can pass to engage the paper and press against a bar in the performance of the feeding (Cl. B12- 39) operation, in the manner below described. The front wall of the closure is cut out at the bottom as at and has mounted at its inner side and projecting slightly below the top of the cut out portion, a knife 2l having teeth 22, downwardly directed.
Also hinged on the pintle 1 (see Figure 2) is a plate 25. Above this plate is a plate secured between plates 39 and 40 having its top bent to provide a smoothing edge 21, against which the paper moves when being fed. The plates I6 and 425 are spaced to form a guide throat leading downwardly to the delivery opening 20, and directing the paper into tear-off relation with a knife 2| so that tear-off can be accomplished by up-pull on the paper. The tear-off edge is concealed. The element forms the front of the supply chamber. The paper roll 3i] is supported directly by the bottom 3. Numerals 3|-32 respectively indicate a measuring roll and a pinch roll, with which the paper is frictionally engaged. When the paper is pulled the rolls are rotated. The measuring roll performs the usual function. A guard, or guide 33 is arranged as shown to direct the paper (after its passage between the rolls) upwardly and outwardly to pass over and against the smoothing edge 21, to be disposed in front of a hand or finger-operable swinging bar 35, see Figures 1 and 2. This bar has a centrally arranged finger receiving depression 36 into which the paper is pressed. The bar is swingingly connected at opposite ends by arms 31 which are pivoted as at 38 to plates respectively indicated at 39 and 40. These plates extend from the front to the back of the cabinet, are spaced from its ends 4 and 5, and are suitably secured as at 4l to the rear wall 2.
To the inner sides of these plates are attached bridging plates 43, the inner surfaces of which together act to limit the end movement of the roll, and prevent its contact with parts of the mechanisms now to be described, and parts of which are mounted at or project inwardly beyond the inner faces of the plates 39 and 40.`
The paper lies in front of the bar and bridges the depression, and lies against the front face of an apron 45 which depends from the lower front side of the bar 35 and which apron forms a ledge or bottom for the depression. The paper is pressed against the back of the depression by the finger, as shown in Figure 2. The paper is visible and accessible through the opening I1 of the front I6. The paper when so pressed is frictionally held to be entrained to accessible position as shown in Figure 2.
lil.
Stop lugs 41 (see Figure 2) limit downward movement of the bar 35, these lugs being engaged by the arms 31. Upward movement of the bar is limited by the engagement of these arms with stops 48. Both stops 41 and 48 are preferably punched out of the plates 39 and 4D. A spring 5U moves the arms upwardly, and yieldably resists feeding motion, whereby to require sufficient finger pressure of the paper against the bar to prevent slippage of the paper relatively to the bar, in the case where a pull on the paper is depended upon to rotate the roll.
A ratcheting mechanism may or may not be provided to positively rotate the roll, in lieu of the roll operation by paper only. This positive roll-driving mechanism is sometimes required to relieve pulling strain incident to entrainment by finger action particularly when soft paper is used. The roll 3| has a ratcheting wheel 56 with which cooperates a curved pawl 51 pivoted as at 58 to one of the arms 31. A spring 6G yieldably presses the pawl into ratcheting relation with the wheel 56. The pawl 51 passes upwardly through an opening 6I in the guide plate 33. When the bar 35 is depressed the ratcheting mechanism drives the roll, and preferably the peripheral speed of the driven roll is slightly greater than the peripheral speed of the bar 35 so that at no time is there any substantial pulling strain on the paper, such as would tear it, which tearing is most liable to occur when the users hands are wet, and when softer grades of paper are used.
An important feature of the invention is the scheme whereby action of the bar, to feed the paper controls part of the stop mechanism to release the same as soon as feeding begins. The operation can be obtained with the finger pressing the paper against a control bar, or in other ways.
Referring rst to Figure 1, the roll 3l has rotatable thereby, a gear 1l meshing with a gear 10 journaled on plate 4|). The gear 10 has a stop lug 12 which normally occupies the position shown in Figure 1 and moves in clockwise direction from the position shown. The gear ratio is such that a number of rotations of the gear 1I and therefore of the roll 3i are necessary to obtain a single rotation of the gear 1E). Thus to take from the cabinet the total amount of paper allowed, before the stop mechanism arrests feeding movement pumping action of the bar is necessary, that is, its movement up and down a number of times is necessary. The paper of course can be obtained without pumping by merely once depressing the bar 35 to feed or project the paper to the visible and accessible position shown in Figure 2, whereafter the paper can be drawn out by hand as in Figure 1, until limited by the stop. Referring to Figure 1 it is noted that when the paper is torn olf the paper is invisible. The remainder of the stop mechanism includes in this instance a kind of bellcrank lever indicated at 15 and pivoted as at 16 to the plate. Of course other forms of lever or detents may be employed. One arm of this lever has a shoulder 11 engageable by the stop 12 to arrest movement of the gear 1e and therefore of the roll 3|. The lower face of the other arm of the lever is provided with a forwardly slanted shoulder 19 with which is normally engaged a lug carried by an extension 8l of one of the arms 31. This lug 80 passes through aV slot 83 in the plate 4B to engage the shoulder 19. As the bar 35 is pushed downwardly the lug 8i] moves forwardly, or in anti-clockwise direction in Figure 1, to finally assume the position shown in Figure 2 whereat the upper arm and shoulder 11 is moved out of path of the lug 12, and held there until the bar again reaches its uppermost position. The lever 15 is weighted as at 85 and therefore has means to automatically move it to stop position. Of course, the lever is moved away from stop position against the action of this means. Just as soon as the bar starts to move downwardly the lever is promptly moved outwardly to release the lug 12.
It will be noted, see Figure 1, that there is a slight space between the lower side of the lug 12 and the shoulder 11. To obtain and maintain this spaced relation after each stopping action and to permit the lever to move to release position before the lug engages the shoulder 11 (which might jam the mechanism) there is provided, what I call, a backoff mechanism. This backoff mechanism includes a disc arranged at the inner side of the plate 40 and secured by a screw 9| to move with the gear 10. The disc has a shoulder 93, which near the end of the feeding rotation of the roll, engages with a roller 94 carried by an arm 95 pivoted as at 93 to a plate 40 and yieldably pressed by spring 91 toward the disc 9D. This mechanism is claimed in combination beca-use of its backoif function to position the lug 12 and shoulder 11 for the purpose set forth.
I believe myself the first to provide a device in which the paper is pressed against an element, which when moved to feed the paper operates to disengage a stop mechanism and hold the same disengaged during the feeding operation.
It is noted of course that although the lever or detent will move toward or away from stop position respectively as the bar moves upwardly or downwardly, yet during this pumping of the bar no stopping action will be had until a number of pumping actions have occurred or until a pull on the bottom edge of the paper rotates the rolls sufficiently to bring the stop into position shown in Figure 1.
The paper must be either pumped out, or pumped and pulled out. The bar cannot be lowered without pressure of the paper against it. With the finger against the paper, even though the bar is in its lowermost position and the stop disengaged, the paper cannot be pulled out indefinitely, because with such pressure against it, it is frictionally held. If the bar is released it will of course ily upwardly and release the detent, which will then move to stop position and eventually be engaged by lug 12 to prevent further pull out of the paper until the bar is again operated.

A sheet dispensing device having a cabinet invisibly housing a measuring roll with which the paper is frictionally engaged, a stop mechanism for the roll including a rotatable element having a stop thereon, a detent adapted to automatically swing into stopping relation with the stop, a swinging feed bar against which the paper lies after passage over the measuring roll and against which the paper is pressed to pull the paper out as the bar is depressed to feed the paper, and means by which the bar moving in feeding direction operates the stop mechanism to release it and maintain it in released position while said feeding motion continues.
7. A sheet dispensing device having a measuring roll with which the paper is frictionally engaged, a stop mechanism for the roll including an element rotated by the roll and having a stop lug thereon, and a stop lever and means for automatically swinging it into stopping relation with the lug, a swinging feed bar against which the paper lies after passage over the measuring roll and against which it is pressed to pull it out as the bar is depressed, means by which initial feeding motion of the bar operates the stop lever to release it and maintain it in released position as said feeding motion continues, and means oper ated as a result of bar motion to positively drive said roll to feed the paper in a manner to relieve the pulling strain thereon incident to finger action.
8. A mechanism for dispensing sheet material having, a measuring roll, a stop mechanism for said roll including arotatable element having a first stop, and a second stop normally in the path of the first stop, means by which the rotatable element is driven by the roll to make a single revolution as a result of repeated revolutions of the roll, means operable by the user for positively driving the roll, and means by which the useroperable means operates said second stop to release the same When roll-driving action begins and to hold the same in released position while driving action continues.
9. A mechanism for dispensing sheet material having, a measuring roll, a stop mechanism for said roll including a rotatable element having a rst stop, and a second stop normally in the path of the rst stop, means by which the rotatable element is driven by the roll to make a single revolution as a result of repeated revolutions of the roll, swinging means operable by the user for positively driving the roll, and means by which the swinging means operates said second stop to release the same when roll-driving action begins and to hold the same in released position while driving action continues, said swinging means including a part against which the paper is pressed and pulled by the finger during feeding.
