Definitions

  • the invention relates to a cabinet for a roll of towel and more particularly but not exclusively to a cabinet for a roll of paper towel.
  • Towel cabinets housing a roll of towel material are well known.
  • an exposed reach of towel is grasped by the user for drying his hands and fresh towel is withdrawn from the cabinet by pulling on the exposed reach.
  • Soiled towel is normally fed back into the cabinet to be re-reeled therein or otherwise stored within the cabinet.
  • a main drawback to the use of paper towel is that the strength of such a towel, which must be produced relatively cheaply to be viable, is necessarily less than that of a linen towel. Rupture of a paper towel is therefore a reasonably likely event where this towel may be subject to careless use or even vandalism.
  • a towel cabinet comprising a housing for supporting a roll of fresh towel material which is manually withdrawn from the cabinet in use, and control means operated by withdrawal of the towel material from the cabinet and adapted to oppose continuous withdrawal of material from the cabinet; said control means being arranged such that the tension created in the material as a result of the opposing force provided by the control means does not exceed a predetermined value.
  • the cabinet shown in Figure 1 is normally mounted on a wall or other suitable surface by means of its rear wall 1 and generally comprises a housing having an upper portion for supporting and containing a roll 2 of web material for use as a hand towel, mechanism for dispensing such towel under controlled conditions, and a bin section 13 for retaining soiled towel after use.
  • the cabinet has been,particularly designed for use with a roll of paper towel material and reference to such a roll will be made throughout this description although a conventional linen roll-towel could also be employed.
  • the roll 2 is supported within the housing in a tray 3 and access to the interior of the housing for loading is achieved by means of a hinged lid 4.
  • a web of paper towel from the roll 2 passes between outfeed rolls 5 and 6 and thence out of the housing via a gap formed between a depending portion of the lid 4 and a front wall 7 of the housing.
  • a guide plate 8 serves to guide the web and to prevent the roll climbing out of the tray 3.
  • the roll is free to move and unroll in the tray 3 but may alternatively be mounted for rotation about its axis in known manner.
  • a long and substantially vertical exposed reach 9 of paper towel is presented at the front of the cabinet. It is this reach of towel which is grasped for hand-drying and for pulling clean towel from the roll. At the bottom of the reach 9, the towel passes upwardly and back into the cabinet between a pair of infeed rolls 14 and 15 and thence into the bin section where it is retained.
  • Outfeed roll 5 is driven when towel is pulled from the roll and is drivingly coupled to a first of the infeed rolls 14, by means of a drive belt 16 or other suitable means.
  • Figure 2 and 3 show details of the cabinet which assist in the controlled dispensing of towel. It is well known in the field of towel cabinets to provide stop a mechanism for limiting the length of towel which can be pulled out of the cabinet at one go. It is also well known for such stop a mechanism to be held in its operative position for a set period of time by means of suction cups.
  • a suitable device is shown in Figures 2 and 3 which show a cam 18 in the form of a profiled disc mounted for rotation on a shaft 17 on the end of the outfeed roll 5 and a cam follower and stop arm 19 mounted for limited rotation about an axis 20.
  • the arm has a first limb 21 which in the position shown prevents the continued rotation of the cam 18 and hence the roll 5.
  • a first suction cup 23 Mounted on a second arm 22 is a first suction cup 23 which cooperates with a second fixed suction cup 24 to retain the arm 19 in the position shown in Fig. 3. Air leakage into the suction cups, and thus the period during which they operate, is controlled by means of an adjusting screw 25.
  • Suitable gearing between the cam 18 and the roll 5 may be arranged to provide for suitable lengths of fresh towel to be dispensed.
  • a friction override clutch may be incorporated between the cam 18 and the roll 5.
  • the stop mechanism is effective will not cause tearing of the towel since the clutch will slip and allow towel to be pulled from the roll 2.
  • the cam 18 is held between two plates 42 and 43 which are fixed in rotation with the shaft 17 which is located at one end of the roll 5 and by means of which the roll is journalled for rotation.
  • the plate 42 is free to move axially on the shaft 17 and clamps the cam 18 between the plates 42, 43 under the action of a spring washer 44.
  • the clamping action of the spring washer 44 is adjustable by means of a nut 45 threaded on the end of the shaft 17.
  • Figure 4 shows an alternative device for regulating the withdrawn of towel from the roll 2.
  • a coil spring 36 is housed within a spring barrel 37 and connected at its inner end to the shaft 17. The outer end of the spring is connected to the inner surface of the spring barrel 37 which is mounted for rotation on the shaft 17.
  • the outer periphery of the spring barrel 37 may be toothed for co-operation with a toothed cog 39 or may have a friction surface for co-operation with a friction wheel.
  • the cog 39 or friction wheel is journalled for rotation on a shaft.40 and a vane 41 or other damping and dissipating device is fixed on the shaft 40.
  • the operation of the regulating device shown in Figure 4 is as follows.
  • the roll 5 is caused to rotate.
  • This causes the shaft 40 and vane 41 to rotate through the intermediary of the coil spring 36 and the spring barrel 37.
  • Air resistance on the vane will thus oppose the rotation of the shaft 41 and the coil spring will tend to be wound up.
  • Resistance to withdrawal of towel will thus increase gradually up to the point where the coil spring is completely wound up and in this way an abrupt interruption of withdrawal is avoided.
  • a one way drive (not shown) is also incorporated into the device to prevent the roll 5 being driven in reverse by stored energy in the spring when the user releases the towel.
  • the damping and dissipating device will be suitably designed such that the opposing force which it provides does not exceed the required predetermined level.
  • a friction clutch may be incorporated between the roll 5 and the damping and dissipating device.
  • the coil spring 36 might be connected at its inner end to a sleeve frictionally fitted over the shaft 17. The adjustment of this friction clutch being carried out by means of the nut 45.
  • FIG. 5 there is shown an alternative version of a friction clutch which in this case is built inside the roll 5 which is covered in a layer of elastomeric material to provide good grip between the roll and the towel material.
  • an elastomeric friction block 50 Fitted into an open end of the roll 5 and keyed thereto is an elastomeric friction block 50 which has an internal conical surface 51 engaging an external conical surface 52 on an extension of the cam 18. The two conical surfaces are urged together by means of a spring 53.
  • the shaft 17 may be fixed; the rollers being journalled for rotation thereon at one end by the block 50 and cam extension as shown in Figure 5 and at the other end by any suitable means.
  • the frictional contact between the surfaces 51 and 52 is adapted to allow the clutch to slip when the tension in the towel material exceeds the predetermined value.
  • the cabinet described with reference to Figures 1-5 is particularly advantageous for use with a paper based or other disposable towel.
  • the towel strength is about 180-200 lbs.
  • the setting of the clutch employed in any circumstance will naturally be determined by the nature of the web being employed.
  • the normal "pull" required to operate known roll towel cabinets is of the order of 3 - 6 lbs.
  • the minimum setting of the clutch mechanism must be sufficiently strong to give a measure of feel and should be set at least 2 - 3 1bs above the operating pull.
  • the preferred range of clutch settings is in the region of 10 - 25 lbs. This is a small proportion of the strength of a suitable paper towel across its width but it should be borne in mind that the pull on the towel will, in practice, be concentrated in the edge regions of the towel and parts of the towel will be greatly weakened by wetting.
  • a suitable towel for use with the cabinet comprises a web formed from two layers of absorbent paper materials having a layer of perforated plastics material therebetween.
  • the edge portions of the web may be provided with elongate reinforcing elements.
  • the reinforcing elements may suitably extend inwardly beyond the edge portions to the parts of the web which tend to be engaged by a user's thumbs. The provision of reinforcing elements in these areas will substantially reduce the likelihood of the user's thumbs bursting through the web.
  • the setting of the control means should be such that the opposing force provided thereby does not exceed 75% and is preferably less than 50% of the tensile breaking strain of the towel across its full width.
  • the bin section will be adapted to allow emptying. This may conveniently be achieved, for example, by mounting the bin section removably on the cabinet or by the provision of a closure which can be opened to afford access to the bin section.
  • the material when fed back into the cabinet may be re-reeled or as shown may be fed upwardly reeled into a collecting bin. Alternatively the material may be allowed to fall unreeled into a collecting bin.
  • a paper towel Although described in relation to use with a paper towel, it will be clear to those skilled in the art that the cabinet can also be usefully employed with linen towel.
