17 Claims.
Our invention relates to a machine for dispensing paper towels from a roll whereby the paper may be severed into lengths suitable for individual wipes.
In the above type of paper towel dispenser, an object and feature of our invention consists in providing a cutter by which the length of paper may be cut or torn to obtain a length for a wipe and thus have the severed end at the opening in a cabinet or the like, together with a mechanism manually operated to give an initial feed for a small portion of the towel, whereby the severed end is caused to project from the cabinet a sufficient distance to allow grasping by the hand. Thus when the end is grasped a person may pull a length of paper out of the cabinet by unrolling the roll mounted therein, such length being sufiicient for a single wipe. In connection with this, another object and feature of our invention is forming a positive stop mechanism whereby as the desired length of paper has been unrolled from the supply roll, a positive stop or resistance is developed, preventing a further unrolling or pulling out of the paper.
Another and further object of our invention resides in a time delay mechanism which is automatically set on pulling the paper from the cabinet and thus unwinding the roll and this cooperates with the positive stop mechanism, whereby after a predetermined time the stop mechanism is opened or released for a further operation so that the next user may obtain the desired length of towel for a second wipe. This delay featureis in part for the purpose of preventing a person continuously withdrawing or unwinding an unnecessary length of paper from the roll, as when the user finds that the roll is brought to rest so that he can not withdraw any more paper, he will sever the strip already pulled from the cabinet and use such strip. Further, the user will have to wait the predetermined time for which the machine is set before he can secure a further length of towel from the cabinet.
A further detail object of our invention resides in the feature of an initial feed to project the severed end of the web so that the operator may grasp such end to remove a length of towelling. However, this initial movement does not set the time delay mechanism, thus it is only the positive unwinding of the paper to secure a length for a wipe which develops the operation of the time delay device with a positive stop mechanism. A further detail feature includes a manual control for the delay mechanism by which the length of time of the delay may be varied.
Another object and feature of our invention resides in the manner of supporting the paper roll and feeding the paper therefrom in which we develop considerable friction for unwinding the roll by supporting substantially the whole weight of the paper roll on a friction roller.
Another object and feature of our invention is having a friction feed roller comparatively small in diameter compared with the roll of paper towel to be dispensed and having the paper roll contact with the friction roller whereby considerable friction is developed between the friction feed roller and the paper, and in connection therewith controlling the number of turns of the friction feed roller by gearing connected to a stop mechanism to feed the desired length of paper to be severed.
Another object and feature of our invention is in engaging the paper Web in a bite formed by the friction feed roller and a slightly adjustable feed roller, this latter projecting through an opening in the cabinet to be manually operated to give either an initial or a complete feed to the web of paper.
Our invention is illustrated in connection with the accompanying drawings, in which,
Fig. 1 is a vertical section on the line l--I of Fig. 2, taken in the direction of the arrow, the feed roller being shown in elevation.
Fig. 2 is a vertical section on the'line 2-2 of Fig. 1 in the direction of the arrows, the escapement stop lever and connected parts being shown in elevation, this illustratingthe position of the escapement lever after releasing the stop pin.
Fig. 3 is a section similar to Fig. 2, showing the escapement stop lever pulled downwardly by the stop pin and the piston of the dashpot pulled outwardly.
Fig. 4 is a perspective view of a cabinet suitable for housing our paper dispenser.
Fig. 5 is a partial side elevation taken in the direction of the arrow 5 of Fig. 1.
In our invention we employ a cabinet ll having a door [2 on the front, this door having an opening l3, the side of the cabinet having an arcuate slot M. The door has an undercurved section l5 adjacent the bottom with a serrated cutting edge l6 for severing the separate sheets of paper from the strip. This severing edge is located in front of the forward edge ll of the bottom l8 of the cabinet. The cabinet is illustrated as having a back wall l9, a top 20 and two opposite sides 2|. The door may be hinged or secured in position on the front of the cabinet in any suitable manner.
In the cabinet we utilize a pair of side supporting plates 25 and 28, these being illustrated as attached to the back of the cabinet. Each of these plates has a slot 21 forming a guide for the axle 28 of the mandrel 29 on which the web of paper is formed into a roll 30. Journaled in the sides 25 and 26 is the axle. 3| of the friction supporting and feed roller 32. The axle of this roller is positioned slightly in front of a continuation line of the center of the slots 21 which slots slope forwardly towards the front of thecabinet. The friction roller is covered by friction material of a suitable type and forms the sole support for the roll of paper toweling. It will thus be seen that a vertical line through the axle 28 of the paper roll is spaced inwardly from the axle SI of the supporting and feed roller. The weight of the roll gives sufficient pressure to cause the friction for feeding the paper in the manner hereinunder detailed and also as the roll becomes smaller, there is a forward Wedging action between the diminished paper roll and the supporting friction roll.
Upwardly extending fingers or a plate 33 secured to the bottom of the cabinet adjacent its front edge l1, prevent the web of paper from clinging to the friction roll as the paper web passes down in front of the edge H, the section of the web after severing being indicated at 34 (Figs. 1, 3 and 5).
The manner of feeding the paper comprises using a large feed roll 40, this being mounted on a mandrel 4i having a shaft 42. The shaft is journaled in slots 43 in the side plates 25 and 26. The peripheral portion 44 has a resillent or roughened surface preferably formed of thick rubber. Tension springs 45 are connected between the axles ll of the supporting friction roll and the axle 42 of the feed roll. Thus the peripheral resilient surface structure 44 of the feed roll 40 contacts the outer face of the web of paper while the inner face follows the cylindrical curve of the supporting friction roll. Thus by engaging the exposed portion of the rubber covering 44 of the roll 40 and moving it in the direction of the arrow 45, it engages the web of paper between the feed roll and the friction roll and moves the web of paper downwardly in the direction of arrow 41. were it not for the stop mechanism having the escapement hereinunder detailed, a person could unroll as much paper as was desired from the web by merely continuously rotating the roll 40 in the direction of the arrow 46. If it is desired to have the complete feed operated by manipulating the exposed section of the roll 40, the springs 45 can be omitted as the pressure of the hand can move the roll 40 in the slots 43 sufficiently to obtain sufficient operating friction between the roll 40 and the web of paper and between the paper web and the surface of the friction roll. However, even if this device is manipulated by the exposed portion of the feed roll 40, it is desirable to have the springs 45.
By our invention we desire to limit the amount of paper a person can secure for one wipe and give a time delay. Moreover, it is our desire that the roll 40 be only used to give an initial feed of the paper web in order to project the portion of the web above the severing edge l5 which portion is in the cabinet to project it by the operation of the roll 40 slightly below the cabinet as indicated in dotted lines in Figs. 1
and 2; then this slightly projected portion may be grasped by the fingers and the web of paper unwound.
The control of the paper feed is by means of a positive stop mechanism, indicated as a whole by the assembly numeral 5.. This employs a gear 5! secured to the shaft 3! of the supporting and friction roll. Such gear meshes with an idler gear 52 mounted on a shaft 53, which shaft is illustrated as being mounted in the side plate 25 and in a bracket plate 54 secured to the plate 25. This idler gear has a stop pin 55 secured thereto. An escapement lever 56 is mounted on a pivot 51 secured to the bracket plate 54. It has a lever end 58 with a cam surface 59 onits under edge and a hook 60 with an escapement end 6| on the opposite side of the pivot 51. The opposite end 62 of the arm is connected to a. tension spring 53 which at its upper 2nd is secured to a pin 64 attached to the plate The manner of operation and functioning of the machine so far described is as follows: Presuming the paper is properly threaded between the feed roller 40 and the friction roller 42 and the roll of paper entirely supported on this latter roll, the movement of the forward roll 40 in the direction of the arrow 46, projects or extends the end of the web or the severed end after sheets have been removed below the cutting edge [6 of the door, so that this end may be grasped by hand, which end is then pulled downwardly and if the escapement lever is in the position of Fig. 2, the idler gear 52 rotates in the direction of the arrow 65, thus bringing the stop pin in contact with the cam surface 59 of the escapement lever and tilting it to the full line position of Fig. 3 so that the pin 55 is secured in the hook 60, the pin being shown in dotted lines in Fig. 3. A portion 66 of the cam surface 59 adjacent the hook to is substantially concentric with the shaft 53 when the escapement lever is tilted to the position of Fig. 3. Thus when the pin 55 catches in the hook 60, a positive stop prevents the rotation of the idler gear 52 and hence of the friction feed roll 32 on account of the gear 52 meshing withthe gear 5| on the shaft 3| of the friction roll.
It will be noted that certain characteristics of the equipment lever 56 include as important elements the hook 60 which forms a detent with the escapement and BI and the portion 66 of the cam surface 59. The portion of the surface of the hook from its base to the escapement and Si is such that when the lever is being tilted for instance from the position of Fig. 3 to that of Figs. 2 and 5, the pin 55 readily passes this escapement end 6|.
The time delay mechanism designated by the assembly numeral II employs a dash-pot II, this being in the form of a cylinder attached by a clamp 12 to the side plate 25. This cylinder has a head I3 with a large opening II. A plug II at the opposite end has a needle valve I5, this having a conical valve seat 11, a rotatable needle stem 18 and outlet ports 19. The stem has a screw driver kerf for adjusting and regulating the opening of the needle valve. The piston ll has a piston cup 82 with the edges turned inwardly. The piston rod 83 is connected by a pivot pin ll to a slot 85 in the end 52 of the escapement lever 56.
The manner of operation and functioning of the time delay assembly is as follows: When the paper is pulled out rather quickly, preferably by grasping the projected end, the pivot 51 on the idler gear swings the escapement lever 56 from the position of Fig. 2 to that of Fig. 3, .thus tensioning the spring 63 and at the same time,
pulling the piston outwardly in its cylinder. A
certain amount of air enters the cylinder by passing inwardly around the periphery of the cup and prevents the formation of a vacuum. Also a certain amount of air enters through the outlet ports I9 and around the needle of the needle valve. As
above mentioned the hook 60 forms a positive stop.
to the movement of theidler gear, hence the gear and the friction and supporting roll 32. Hence, neither by pulling on the web of paper or by operating the roll 40, can a person secure more paper while the pin 51 is engaged by the hook 60. The person therefore naturally tears oil the strip of paper that has been pulled out of the cabinet,
cutting or tearing this against the serrated edge I6 of the lower end of the door. This as above mentioned severs the paper at the bottom of the cabinet. The spring 63 then pulls upwardly on the escapement lever, moving this in the direction of the arrow 86, causing the piston to move inwardly, but as this piston is moving in a direction against the free edges of the cupped washer 82, the only escape of air from the dash-pot is through the needle valve and the exhaust ports I9. These can be regulated to give a slow exhaust. This action under theinfluence of the spring 63, moves the escapement lever 56 from the porition of Fig. 3 to the position of Fig. 2, so that the escapement edge 6! of the hook is at a greater radial distance from the center of the shaft 53 than the pin 55. This leaves the mechanism in condition for dispensing an additional sheet of paper, but on account of the time delay ordinarily a person will not wait until the escapement mechanism operates to secure a further sheet of paper, but is satisfied with one sheet for a wipe. Thus the device economizes in the use of paper.
As an additional mechanism for initially operating the feed roll 38, we employ a ratchet lever 90, freely pivoted on theend of the shaft 52 of the feed roll till, this preferably being the end i which is journaled in the plate 26. A handle 9i extends through the arcuate slot NE in the side of the cabinet M. A tension spring 92 is secured to the ratchet lever and also to a portion of the cabinet preferably to the wall 2i on the inside, in order to normally hold the handle at the upper end of the slot It. A pivoted pawl 93 engages a ratchet gear 9 on the shaft 62 of the feed roll 40; this pawl being held in place by a spring or the like so that on the motion of the ratchet lever 90 and handle 9! in the direction of the arrow 95, the feed roll 50 is rotated the length of the slot M and gives an initial feed to theweb of paper, projecting a sufiicient amount such as shown dotted in Figs. 1 and 2, to be grasped by the fingers of the user.
When reliance is made on the handle 9! to feed the paper, it is desirable to have the springs i5 pulling the feed roll 80 into tight contact with the web of paper. This handle 9! is provided for the use of people who may be unfamiliar with the operation of the machine, by directly pres ing against the roll it. As the feed roller may be operated entirely by the handle 9!, it is obvious that the feed roll 40 may be housed completely in the cabinet, in which case the door does not have an opening as indicated at I3.
Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.
