16 Claims. (Cl. 312-38) The present invention relates generally to a towel dispenser, and relates more specifically to a dispenser for use primarily in connection with continuous roll cloth toweling.
Heretofore, with dispensers for use with continuous roll cloth toweling, a roll of such toweling was suitably placed in a dispenser cabinet and connected to a rewind mechanism. When the roll of toweling was exhausted, the trailing end thereof was commonly pulled free and permitted to hang downwardly, thus indicating the need for replacement of the roll. In many instances, servicing of the dispensers had not been at sufficient intervals as to enable replacement of the toweling before all available dispensers were exhausted. Accordingly, it had been necessary for individuals to either forego the use of such toweling or to resort to the use of soiled portions of the toweling. Practices of this type are not only unsanitary but additionally are contrary to the desires of most individuals.
Efiorts to provide larger dispensers utilizing longer rolls of toweling still present the same problem, inasmuch as the soiled rolls are generally not replaced until the roll is entirely exhausted. In other instances, efforts have been made to provide a second roll of toweling which would be available after a first roll was exhausted. However, the prior devices employing such a principle have failed to achieve continuous towel service that operates automatically when a new roll is to replace one that has been consumed, and none of them has included any facilities by means of which the dispenser could be serviced to provide continuous towel service prior to complete consumption of the second or spare roll of toweling without requiring removal of the roll itself.
One important object of the present invention, therefore, is to provide a novel towel dispenser wherein a dual supply of toweling is arranged in a manner permitting continuous exposure of such toweling at a point of use, together with means for independently collecting each of the toweling rolls whereby to permit servicing, i.e., independent removal of soiled toweling from one roll, prior to complete exhaustion of another roll.
It is another important object of the present invention to provide a novel towel dispenser wherein various portions of the dispenser and mechanism utilized therein serve a dual purpose in order that there may be a saving in space within a suitable cabinet enclosing the dispenser.
A further important object of the present invention is to provide a towel dispenser having novel means for releasably connecting one roll of toweling with a second roll of toweling in a manner permitting end to end rela servicing the dispenser the first roll is removed while the second roll remains active and a new reserve roll is added,
and so on, to provide continuous towel service even when an active roll is consumed.
Other and further important objects of the present invention will become apparent from the following detailed specification taken in connection with the accompanying drawings, wherein:
Figure 1 is a perspective view showing the towel dispenser of the present invention;
Fig. 2 is a vertical sectional view through the dispenser, as taken substantially as indicated by line 2-2 of Figs. 1 and 3;

Figs. 9 through 13 schematically illustrate the mechanism of the present dispenser with parts in various positions in successive stages of operation.
With reference to the drawings, the towel dispenser of the present invention comprises a frame structure, indicated generally at 10, which supports an ornamental housing or cabinet 11. The forward portion of the housing 11 is provided with a door 12 that is movable about a horizontal hinge 13. The door 12 is provided with a mirror 14 located on the upper forward portion thereof and a lock 15 secures the door in position. One of the side panels 16 is provided with a viewing window 17 through which the supply of toweling may be seenin order to determine whether there is any need for service without actually opening the cabinet. I
As shown particularly in Figs. 1 and 2, the frame structure it comprises generally vertically disposed side plates 20 that are maintained in spaced relationship by a plurality of interconnecting rods 22 and a channel bar 24. A lower shelf 26 is disposed between the lower ends of the side, plates 20 and secured thereto by flanges 28 and screws or the like 30. The shelf 26 has a bottom wall portion 32 and a curved outer end portion 34 with generally vertically directed sides, or guide or centering members 36. The rearward portion of the side plates 20 are maintained in rigid spaced relationship by a transversely disposed back guide member 38 that is secured in position midway between the top and bottom of the cabinet by means of screws or the like 40. The lower end of the guide member 3-8 is bent inwardly or forwardly as at 42 in order that a smooth guide surface may be presented Y to-the toweling as it advances toward the guide member.
a In order to provide support means for one of the rolls of toweling in the cabinet, a central or intermediate shelf 44 is pivotally connected at 46 with the sideplates 20.
The shelf 44 has side guide or centering members 48 and.
a curved outer, or front, end portion 50 that normally rests upon the transverse channel 24.
A first or active supply roll of toweling T is adapted to rest upon the central shelf 44 with toweling extending therefrom, about the outer, or front, end of the portion 50 of the shelf 44 and about a pressure roller 52. The pressure roller 52 is carried by a shaft 54 which is journaled in slots 56 in the side plates 20. The toweling thereafter passes about a primary drive roller 58 that is carried by a shaft 60 which is journaled in bearings 62 carried by the side plates 20. The outer surface of the roller 58 is coated with a frictional material and the pressure roller 52 is biased toward the frictional material which is disposed in the upper rearward portion of the cabinet and mounted on a suitable shaft 72 which is journaled in the side plates 20. The outer surface of the roller 72 is also provided with a frictional material and the toweling is maintained in contact therewith by means U of a pressure roller 74 having a shaft 75 rotatably disposed in slots 76 in the side plates 20. From the secondary drive roller 70, the toweling passes to a collecting o'r take-up station indicated generally at 78.
In order that the loop L in the portion of the toweling hanging below the cabinet may be maintained at a constant length, the shafts 60 and 72, associated respectively with the drive rollers 58 and 70, extend beyond the outer surface of one of the side plates 20 and have afiixed thereto sprockets 80 and 82, as shown in Figs. 3 and 4. A chain 84 is disposed about these sprockets, and about an idler sprocket 86 and a soiled portion roll-driving sprocket 88. The rollers 58 and 70 are of equal diameter, and the sprockets 80, 82 and 88 are also of equal diameter. The sprockets 86 and 88 are mounted on shafts 90 and 92 which are in turn carried by one of the side plates 20; The sprocket 88 has associated therewith a ratchet 94 and a leaf spring pawl 96 which restricts movement of the chain to one direction, as indi cated by the arrow 97 in Fig. 4. The ratchet 94 also serves as a gear for driving a mating gear 98 that is carrred on a shaft 100. The shaft 100 is rotatably disposed in generally horizontally arranged slots 102 in the side plates 20. The shaftllltl supports a rewind roller 104 which'is disposed between the side plates 20. The ends of the rewind roller 104 terminate with gears 186 which are used for a special purpose tobe described hereinafter. As shown primarily in Fig. 2, a second, or reserve, supply roll of toweling T is adapted for rotatable disposition upon the lower shelf 26. By means of an interconnecting flexible structure 108, the trailing end of the first, or active, supply toweling roll T and the leading end of the reserve toweling roll T are connected together, so that use of the reserve roll is commenced automatically when the first roll is consumed.
The interconnecting mechanism between the two,
toweling rolls is shown primarily in Figs. 6, 7, and 8. As shown in Fig. 8, the connection to the leading end of the second towel-ing roll comprises a transversely disposed elongated shaft 110 that has an elongated clamp member 112 pivoted at 114 to one end thereof. The clamp member 112 is provided with teeth 116 so as to provide means for positively engaging the toweling beassumes tween the clamp member and the shaft 110. The clamp member is locked in position by means of a pin lock member 118 at the end of the shaft remote from the pivot 1-14. The outer ends of the shaft 110 carry enlarged bushings 120 which are fixed thereto in spaced relationship to the ends of the clamp member 112. The bushings 120 support gears 122 and, on the outer ends thereof, rollers 124 that are rotatably maintained on the outer end of the shaft 110 by means of pins or the like 126. A pair of flexible cords 128 are looped about the shaft 11% intermediate the ends of the clamping member 112 and the bushings 120. The ends of the cords 128 carry loop connection portions or eyes 130.
As shown in Fig. 7, the loop portions 130, on the flexible cords 128, are adapted to be hooked over ends of a shaft 132 that is clamped to the leading end of the reserve toweling roll T by means of a clamp member 134 similar to the clamp member 112. Washers 1'36 mounted on the outer ends of the shaft '132 serve to retain the loops in position on the shaft. It is thus seen that the trailing end of the first toweling roll T is removably connected to the leading end of the second toweling r-oll T by means of a flexible connection established through use of the interconnecting mechanism 108.
In practice each strip of toweling is attached to a similar shaft 110 and is rolled onto it, and a bar 132 is attached to the outer end of the roll to prepare a roll for use in this dispenser. But when the dispenser is initially loaded the leading end of the first roll of toweling is also fitted with the mechanism shown in Fig. 8 and the toweling is passed over the rollers 58 and 70 in the manner hereinbefore described. The rollers 124, carried by the outer ends of the shaft 110 on the first roll are disposed between stationary stop members 138 that are mounted on the side plates 20 and stationary tracks or guide members indicated generally at 140 (see Fig. 5), and adjacentthe gear 106; The guide members 140 include straight portions 141 that extend diagonally upwardly merging into curved track portions 142 and into generally horizontal track portions 144. The guide members thereafter extend generally downwardly in curved rearward track portions 146. The track members 140 are secured to the side plates 20 by means of screws '148 (see Fig. 2). Thus, the gears 122 at the leading end of the first roll of toweling are meshed with the starting gears 106 so that the latter can rotate the shaft 110 to roll the soiled toweling thereabout as the toweling is manually moved through the device by a downward pull applied manually to the front end of loop L.
As the soiled roll becomes larger, the outer peripheral 1 portion thereof engages the roller 104, which then continues-to take up soiled toweling as delivered from the roller 70 even when the gears 122 are lifted out of mesh with the starting gears 106. As the roll of soiled toweling at the collecting station 78 becomes still larger, the rollers 124 travel outwardly from the driving gear 106 and are supported between movable guide members 150,
which are pivoted as at 152 to the side plates 20, and switch tracks 154 which are pivoted to the side plates 20 at 156. The ends of the switch tracks 154, remote from their pivots 156, are adapted for engagement with the lower ends of the portions 1410f the tracks 140. The outer ends of the pivots 156 extend through the side plates 20 andhave c'ounterwei'ghts 158 (see Fig. 4) connected thereto which serveto bias the switch tracks 154 toward the track portions 141. The tracks have beveled ends 150 (see Fig. 5) that are adapted for engagement with beveled ends 161 of the stop members 1 38,'the tracks 150 being biased into contact with the stops 138 by means of 20. Normally, the latch members 166 engage the tracks 150 at points 170 above thepivots- 15 2 and. rest upon upper Surfaces of the curved portions 142 of the tracks 140. It is thus seen that the tracks 150' serveas guide means for the rollers 124 and thus also serve to support the soiled roll of toweling as it increases in diameter due to accumulation about the shaft 110. Inwardly directed guide plates 172 that are mounted on the side plates 20, and that extend to the space confined between the various portions of the tracks 140, serve to guide the rolling of soiled toweling about the shaft 110 in order to maintain an even roll.
Figure schematically illustrates the condition of the various rolls in the present dispenser just prior to exhaustion of the first active roll T. As this roll becomes exhausted, as illustrated in Fig. 11, the flexible interconnecting mechanism 108 between the active and reserve rolls is drawn over the roller '58. As the toweling is advanced, the mechanism is carried upwardly to the roller 70. Then, as indicated in Fig. 12, as the rollers 124, carried by the shaft 110, pass along the upper surfaces of the portions 144 of the tracks 140, they engage the latch members 166, lifting them to the dotted line position, as shown in Fig. 2, and to the position shown in Fig. 12, thereby permitting the weight of the now-consumed roll of soiled toweling to swing the guides 150 away from the stops 138 and to the position shown in Fig. 12, and permitting the soiled roll of toweling to drop from the collecting station 78 and to where it is stored pending servicing of the dispenser, as shown in Fig. 13.
. In some instances, it is desirable to place a sanitary partition 17-4 intermediate the collecting station 78 andthe central shelf 44, as shown in Fig. 2, in order to prevent contamination of the shelf 44. 'In this instance, the sanitary partition is carried by a transverse rod 176 and is biased toward an upper position, as shown in Fig. 2, by means of tension springs 178 that are also attached at 180 to the side plates 20.
1 Simultaneous with movement of the tracks 150 to the open position, as shown in Fig. 12, levers 180 carried by the outer ends of the pivots 152 for the tracks 150 (see Figs. 2 and 4) are moved downwardly out of engagement with notches 182 in levers 184, which are in turn pivoted at 186 to the side plates 20. The lower ends of the levers 184 rotatably support the shaft 180 intermediate the gear 98 and the side plates so that, upon disengagement of the levers 180 with the notches 182, the shaft 100 is moved in the horizontal slot 102, thus moving the gear 98 out of engagement with the ratchet gear 94. This action permits free'rotation of the shaft 100 so as not to impede movement of the roll of toweling as the soiled roll moves from the collecting station 78 to the waste storage station, as indicated generally at 188, and formed either by the central shelf 44 or the partition 174.
Thereafter, the rollers 124, carried by the leading end of the reserve roll of toweling, pass between the various portions of the tracks 140 and switch tracks 154 and past the lower ends of the switch tracks 154 onto the stop members 138, to be disposed as previously discussed in the collecting station 78 and in position between the guides 140 and the stop members 138. Simultaneously, the tracks 150 return to their original position contacting the stops 138.
At this time the roll T that was previously a reserve roll becomes an active roll. As this roll is used the starting gears 106 commence the winding and the roll grows as explained above in describing the action of the first active roll. But as the second active roll is rolled up the first active roll remains undisturbed in the storage station 188 because of the fact that the shaft 132 turns freely in the eyes 130.
With reference to Figs. 13 and 9, at some time between the exhaustion of the first supply roll of toweling and the exhaustion of the second supply roll of toweling, the dispenser may be serviced. The first roll of toweling, now soiled and indicated at T" in Fig. 13, is disconnected from the flexible cords 128 and removed from the cabinet.
Thereafter, as shown in Fig. 9, the central shelf 44 is lifted to the dotted line position and the second roll of toweling T' is placed upon the open cover door 12. A new reserve roll of toweling is thereafter placed in the bottom of the cabinet and upon the lower shelf 32 with the former reserve roll of toweling now being replaced upon the central shelf 44 in the place of the first roll. While the new roll of toweling is in the base portion of the cabinet and resting upon the lower shelf 32, and the other roll of toweling is resting upon the cover 12, the respective inner and outer end portions are attached together by means of the flexible cords 128 so that the process may be repeated as hereinbefore described.
It will have been noted that the shelf 44 serves a dual purpose in order to enable as much space saving as possible within the dispenser. Initially, the shelf 44 serves as the means for rotatably supporting the first roll of clean toweling and thereafter serves as the storage station for soiled toweling fromthe same first roll as delivered thereto from the collecting station 78. The effect of the particular arrangement in the present invention is that of creating a novel dispenser for. roll type toweling that has,
the various features of noveltyset forth hereinbefore and which may be used in a cabinet only slightly larger than conventional single roll dispensers.
While the present invention has been described particularly in detail with respect to the use of the dispenser for toweling that may be used for drying the hands and the like, it is to be understood that the dispenser may have other applications, such as, for example, for dispensing roller type material for other purposes, and may be employed as such without departing from the spirit and scope of the present invention.
