Definitions

  • the present invention relates generally to improvements in dispensing mechanisms, and more particularly to improvements in the operation and construction of towel dispensers which improvements are especially welladapted for utilization and incorporation in towel dispensers of the so-called continuous type wherein the toweling is made available to the user in the form of a loop of toweling located, in most cases, beneath the dis an structure.
  • 2,899,251 is an example, the clean toweling is led over a measuring roll Within the dispenser cabinet and around a pinch roll and then out of the forward side of the cabinet into the front leg of the depending towel loop.
  • the clean toweling from the supply thereof is withdrawn from the cabinet by the operator who grips the forward leg of the depending loop and pulls downwardly thereon.
  • other mechanism within the cabinet simultaneously winds up a substantially equal length of soiled toweling from the rear leg of the loop. In this manner, the depending toweling loop beneath the prior dispensers is maintained, generally speaking, at a substantially constant length.
  • One of the principal objects of the present invention is to overcome and avoid the above objectionable features of prior towel dispensers and to provide a highly-improved towel dispenser wherein soiled toweling is automatically withdrawn from the use position of the toweling when a user has completed his drying operation, thereby avoiding the unpleasant appearance of exposed soiled toweling and avoiding the possible tendency for the next user to handle or use the previously-soiled toweling.
  • a further object of the present invention is to provide, in an improved towel dispenser of the character just referred to, time-delay means actuated in response to the dispensing of clean toweling to a use position, for use by a first user, and soiled toweling take-up means automati cally actuated in response to the timing out of the timedelay means for withdrawing soiled toweling from the use position, thereby minimizing or avoiding the tendency for the next user to handle that portion of the toweling previously soiled.
  • the withdrawal of the soiled toweling in the present invention thus avoids any health problem that may result from having readily available a soiled portion of toweling for use or grasping by a subsequent user, and the present invention avoids the unpleasant appearance presented by exposed soiled toweling.
  • Still another object of the present invention is to provide, in a continuous-type towel dispenser having the above stated objects and advantages, means for automatically retracting the trailing end of the toweling when the supply of clean toweling has become exhausted, thereby avoiding the unpleasant appearance of a dangling free end of the toweling beneath the dispenser and avoiding the possibility that users may repeatedly use the dangling end of the toweling for drying purposes.
  • a further object of the present invention is to provide a towel dispenser of the aforesaid kind which is relatively easy to maintain and is relatively easy to load and thread with a new supply of clean toweling.
  • Yet another object of the present invention is to provide simple and relativelyinexpensive means for accomplishing the above-expressed objectives, and to provide such means which, by their nature, may be embodied in many existing towel-dispensin g cabinets with a minimum of expense and without extensive modification of the existing portions of the dispensing apparatuses.
  • FIG. 1 is a schematic, vertical, cross-sectional view showing certain principal parts of a continuous-type towel dispenser constructed in accordance with the present invention, the path of the toweling being represented by broken lines, and the apparatus being illustrated in the normal condition occupied by the parts thereof after a user has employed the toweling in a drying operation and soiled toweling has been withdrawn from the use position of the toweling;
  • FIG. 21 s a schematic view similar to FIG. 1, but showing the path of the toweling and the relationship of the parts substantially in the condition occupied thereby when the user has gripped a clean portion of the toweling adja- Cent the place at which the clean toweling emerges from the front of the cabinet and has pulled downwardly on the toweling to cause a clean length of toweling to be dispensed from the cabinet and to cause a portion of the rear leg of the loop of toweling to be withdrawn from the rear portion of the apparatus, so as to provide a loop of toweling beneath the cabinet of sufficient length to permit the user comfortably and conveniently to dry his hands on the clean front leg of the loop;
  • FIG. 3 is an enlarged, fragmentary, vertical, crosssectional view showing the parts of the apparatus as they would be viewed with the wall of the apparatus (nearest to the eye of the viewer) removed, the position of the parts and the position of the path of the toweling corresponding to the positions thereof illustrated in FIG. 1;
  • FIG. 4 is a fragmentary, cross-sectional view similar to FIG. 3, but showing the position of the parts and the path of the toweling in a use condition corresponding to that illustrated in FIG. 2;
  • FIG. 5 is a greatly-enlarged, fragmentary view showing the latching action which retains the towel-retracting mechanism in its lowered position (as illustrated in FIG. 4) until a time-delay mechanism times out, whereupon the towel-retracting mechanism is automatically returned or moved upwardly from the position shown in FIG. 4 to the position shown in FIG. 3;
  • FIG. 6 is an elevational view of the towel-retracting mechanism, taken substantially along the line 6-6 in FIG. 4;
  • FIG. 7 is a cross-sectional view of the upper portion of the towel-retracting mechanism, taken substantially along the line 77 in FIG. 6;
  • FIG. 8 is an enlarged, fragmentary, vertical, crosssectional view taken substantially along the line 3-8 in FIG. 6, showing the position occupied by the towelretracting mechanism when the supply of clean toweling has become exhausted and when the towel-retracting mechanism has been automatically elevated to a position which withdraws into the mechanism the trailing end of the toweling, the trailing end of the toweling being represented in this view by a broken line;
  • FIG. 9 is an enlarged, fragmentary, cross-sectional view taken substantially along the line 9-9 of FIG. 8, to illustrate a portion of the construction of a substantially constant torque spring-motor embodied in the apparatus for elevating or retracting the towel-retracting mechanism;
  • FIG. 10- is an enlarged, fragmentary, cross-sectional view taken substantially along the line 10-10 of FIG. 8, to illustrate a further portion of the means for elevating the towel-retracting mechanism.

  • the opposite end walls 28 and 29 of the trough-like portion of the lower-door construction are respectively pivotally mounted in any suitable fashion upon and between the inner surfaces of the side walls of the cabinet.
  • this pivotal mounting in the present instance has been shown in FIG. 3 to be comprised of a bolt 30 or the like which extends through the wall 29 and is pivotally received in a suitable bracket structure 31 mounted on the inside of the cabinet wall 20. While only one of the pivotal mountings for the lower-door construction is illustrated in the drawings, it will be appreciated that a similar pivotal mounting is employed in conjunction with the cabinet wall not shown.
  • a forward wall 32 extends upwardly to a position adjacent the lower edge of the upper door 23, the uppermost portion of the wall 32 having a protruding lip 33 formed thereon. lip 33 is spaced below the lower edge of the door 23, so as to provide a slot 34 (FIG. 3) through which clean toweling may be dispensed from the cabinet in a manner hereinafter described.
  • the upper door 23 and the forward Wall 32 of the trough-like lower-door structure 25 com prise the front of the cabinet, while the lower curved wall 26 of the trough structure comprises the bottom of the cabinet, with this bottom of the cabinet being disposed between the lower portions of the two side walls of the cabinet.
  • a clean towel supply roll lies loosely within the trough-like structure 25, so that the clean roll of toweling may rotate therein and, because of the pivotal mounting of the trough-like structure 25 between the depending outer side walls of the cabinet, the trough-like structure may be pivoted from its closed position (shown in FIGS. 2 and 3) to the broken-line position thereof seen in FIG. 1.
  • the trough-like structure 25 may be pivoted forwardly to the broken-line position thereof shown in FIG. 1
  • the interior of the cabinet is exposed, and a clean roll of toweling 41 may easily be deposited in the trough-like structure 25.
  • a suitable lock arrangement is normally provided for latching and locking the upper door 23 to the lower trough assembly 25 when the two are in their normal, closed position.
  • a dispensing mechanism is removably mounted within the cabinet structure just described.
  • the frame of this dispensing mechanism, and the means for its removable mounting within the cabinet may be identical to that shown in the above-mentioned patent to R. G. Birr, No. 2,899,251.
  • this particular frame structureand its means for mounting within the cabinet comprise no part of the present invention per se, and inasmuch as the frame structure and its mounting means are fully illustrated and described in the aforementioned Patent No. 2,899,251, they need be only briefly described herein.
  • the frame structure is comprised of a pair of upstanding walls 41 and 42 (FIG.
  • the dispensing mechanism includes a measuring roll 45 rotatably journaled in any suitable fashion upon and between the walls 41 and 42, one end of the measuring roll 45 having a stub shaft 46 fixed thereon, upon which there is fixed a stop member 47 having a plurality of substantially radially extending stop surfaces 48 thereon. Outwardly of the stop member 47 there is a sprocket 49 fixed upon the stub shaft 46, the sprocket being provided with a plurality of teeth 50 about which there is entrained a link-type chain 51, as shown.
  • a pinch roll 52 disposed between the two walls of 41 and 42.
  • This pinch roll is provided at its opposite ends with stub shafts 53 which are adapted to rotate between, and to move vertically between, pairs of inwardlydirected vertical guide walls 54 (FIG. 3) which may be provided by a pair of U-shaped channel members 55 respectively welded or otherwise secured on the inner surfaces of the walls 41 and 42.
  • the pinch roll 52 may rotatably ride against the measuring roll 45, but may be raised with respect thereto when the stub shafts 53 on the measuring roll are raised between the walls 54 of the U-shaped channel members 55.
  • the space between the upper ends of the walls 54 of each of the U-shaped channel members may be open, so that the pinch roll may be lifted out of the cabinet, if desired, when a new roll of clean toweling 40 is being installed, or in the event it should become desirable to remove and replace the dispensing unit without removing the entirety of the toweling.
  • the dispensing unit per se also includes a towel takeup drive roll 56 suitably journaled for rotation between the walls 41 and 42, one end of this drive roll having a stub shaft 57 fixed thereto upon which there is fixed another sprocket 58 having a plurality of teeth 59 thereon engaged by the chain 51.
  • a towel take-up drive roll 56 and adapted to ride thereon, there is a towel take-up roll 60, the towel take-up roll 60 being arranged to rest by gravity on the take-up drive roll 56, so that, when the roll 56 is rotated, the roll 60 and toweling to be wrapped thereon will correspondingly be rotated in the opposite direction.
  • the path followed by the toweling leads initially upwardly from the clean towel supply roll 40, across a segment of the periphery of the measuring roll 45, and then around the pinch roll 52 and thence outwardly through the opening 34 between the upper door 23 and the lower trough-like door assembly 25, as shown in the drawings. From this opening 34, the toweling extends downwardly across the protruding lip 33 on the lower-door face 32.
  • the path thereafter followed by the toweling will be hereinafter described in detail, but it may now be noted that the toweling ultimately returns to the interior of the cabinet along a path 40a leading upwardly through a space 61 provided between the rear wall 27 of the trough-like lower-door structure 25 and the inner surface of the rear wall 21 of the cabinet housing.
  • the returning path 400 of the toweling may engage the uppermost portion of the rear wall 27 of the trough-like lower-door structure 25, and the path thereupon leads upwardly to the towel takeup roll 60, about which the toweling is wrapped.
  • This returning toweling which moves along the path 40a, as will be subsequently explained, is soiled or used toweling.
  • the drive roll 56 will be rotated simultaneously in a clockwise direction with the rotation of the measuring roll 45 and with the dispensing movement of the clean or fresh toweling.
  • This clockwise rotation of the take-up drive roll 56 drives the take-up roll in the counterclockwise direction, as viewed in the drawings, thereby causing to be rolled up on the take-up roll 60 a length of soiled toweling substantially equal to the length of clean toweling dispensed through the opening 34 at the front of the cabinet.
  • the total length of toweling extant between the opening 34 at the front of the cabinet and the space 61 at the rear of the troughlike lower-door construction 25 will remain substantially constant.
