- a drive roller includes a cylindrical tubular body 141 having an abrasive covering 142, such as sandpaper, on the outer peripheral surface of the body 141.
- the drive roller 140 has the abrasive covering 142 thereof shorter in longitudinal extent than the tubular body 141 to provide two uncovered end portions 143 supported in the journals 120 of the support flanges 115.
- the drive roller 140 is, therefore, freely rotatably mounted in the journals 120 and is maintained therein by means of the vertical and rearward restraints provided by the journals and the finger 118 all as hereinbefore set forth.
- the diameters of the used towel storage roller 130 and the drive roller 140 are such that the abrasive covering 142 of the drive roller will contact the peripheral surface of the body portion 131 of the storage roller 130 when the dowels 132 are resting in the elbows 117 of the support flanges 115.
- a pinch roller has a cylindrical tubular body 161 slightly larger in diameter than the roller 140 and has an abrasive covering 162, such as sandpaper, thereon which terminates short of the ends of the body 161 to provide uncovered end portions 163.
- the pinch roller 160 is shiftably and rotatively mounted on the guides 125 with the center of gravity of the roller 160 disposed above the center of gravity of the roller 140, the guides causing the roller 160 to be urged toward the roller 140 for a purpose hereinafter set forth.
- Each of the end portions 163 of the pinch roller 160 as best'seen in FIG.
- a stop mechanism 155 forms one member of a stop mechanism 155 and has a cam 165 out from the end thereof and bent outwardly from a base 166 away from the surface of the roller 160 to form a camming surface 167 which terminates in a free end 168.
- a notch 170 is cut out of each end 163 to form a latch 172'on the pinch roller 160 with the latch 172 being angularly disposed about 200 from the I end 168 of the cam 165.
- the stop mechanism 155 further includes a stop'pawl 180 pivotally mounted to one of the side walls 57. by a shaft 181.
- the stop pawl 180 is generally Y-shaped with an arcuate edge 185 interconnecting a cam follower 190 and a catch 195.
- the cam follower 190 is rests on the bottom plate 65 and more particularly on i the arcuate portion 66 thereof.
- the free end of the roll 201 is fed upwardly to form the reach 202 between the drive roller 140 andthe pinch roller 160 and over the pinch rollerand downwardly past the abutment surface 104 of the towel deflector 100 to form the reach 203 leading out of the opening between the door 90 and the flange 67 into an exposed loop 205 of toweling.
- loop 205 is exposed for use and extends into the housing through the slot 80 formed between the mounting surface and in contact with the lead edges 71 and 76 of the plates and respectively of the towel straightener 69.
- the used toweling 206 from the loop 205 extends upwardly in the housing 55 and around the used towel storage roller 130 to form a roll 207 of used toweling.
- a clean roll of toweling 201 is inserted into the housing 55 after the front door 90 is opened, as shown in FIGS. 2 and 3, the roll resting on the bottom plate 65 and more particularly on the arcuate portion 66 thereof.
- the free end of the roll 201 is fed upwardly between the drive roller 140 and the pinch roller 160 and over the pinch roller and downwardly below the flange 67 of the bottom plate.
- a loop 205 of toweling is provided beneath the bottom of the towel dispenser 50 and then the free end of the toweling is fed upwardly through the slot formed by the towel straightener 69 in contact with the spaced apart plates 70 and 75, the large opening between the plates facilitating the feeding of the free end of the toweling through the slot.
- the central opening between the plates 70 and 75 is sufficiently large to permit the attendant to insert his hand upwardly between the plates to feed the free end of the toweling onto and around the storage roller 130.
- the towel dispenser 50 is in condition for use. It is seen, therefore, that the'storage roller rests in the elbows or rests 117 of the supports 1 15 prior to the time that the toweling is wrapped therearound.
- the effective diameter of the storage roller 130 increases causing the roller to shift upwardly and rearwardly along the ramps 116.
- Clean toweling is obtained from the roll 201 by exerting tension on the loop 205 causing the pinch roller 160 to rotate in a counter-clockwise direction as viewed in FIG. 3. Since the pinch roller 160 shiftably and rotatably mounted on the'guides 125 is continually urged toward the drive roller by gravity and the towel deflector 100 positions the toweling 203 somewhat below the pinch roller, downward pulling on the loop 205 of toweling will rotate the pinch roller and force the pinch roller toward the drive roller 140 causing rotation of the drive roller in a clockwise direction.
- Rotation of the drive roller 140 in a clockwise direction causes the storage roller 130 to rotate in a counter-clockwise direction whereby maintaining the loop 205 of toweling 'at a predetermined size with the used toweling 206 being wound onto the roll 207 which continuously inafter less than one complete rotation of the pinch roller 160;
- FIG. 8 of the drawings the position of the stop mechanism is shown just prior to initiating a cycle of the towel dispenser 50.
- the stop pawl 180 is in its normal position wherein'the weighted end 199 thereof has positioned the catch 195 as shown with respect to the pinch roller 160. In this position, the cam 165 has the end 168 thereof spaced from the end 192, while the catch 195 is spaced from the latch 172.
- the stop pawl 180 achieves a considerable momentum during the rotation of the pinch roller 160 from the position shown in FIG. 8 to that :shown in FIG. 9, so that the stop pawl 180 continues in the direction of the arrow in FIG. 9 to a position wherein the catch 195 and more particularly the stop surface 197 thereof, moves in the direction shown by the arrow to be interposed in the path of the latch 172.
- Continued rotation of the pinch roller 160 beyond the position shown in FIG. 9 causes engagement of the latch 172 with the stop surface 197 of the catch 195, thereby halting further rotation of the pinch roller 160 in a counter-clockwise direction.
- the stop pawl 180 will swing back to the gravity biased position thereof shown in FIG.
- the abrasive cover 162 of the pinch roller 160 while not absolutely necessary for operation of the dispenser 50, is preferred and prevents slippage of the toweling from the roll 201 into the loop 205 after the stop mechanism 155 is engaged.
- Used toweling from the loop 205 is fed upwardly through the slot 80 in contact with the leading edges 71 and 76 of the straightening mechanism 69 to the rear of the housing 55 to prevent folds and waves from forming in the reach 206 of the toweling and, therefore, the roll 207 is substantially flat and is in better condition for later processing.
- the used towel storage roller 130 shifts upwardly and rearwardly and is guided by the ramps 116 of the roller supports 110.
- the towel dispenser 50 lie in the simplicity of construction which permits the storage roller 130, the drive roller 140 and the pinch roller 160 to be mounted without the usual bearings which may malfunction and require repair. Additionally, the stop mechanism ,155 is actuated in response to rotation of the pinch roller 160 thereby preventing excessive wear of the drive roller 140, a desirable feature which permits more consistent driving of the storage roller 130 through the lift of the towel dispenser 50. The fact that the pinch roller 160 is larger in diameter than the drive roller 140 also insures that the abrasive covering 142 will wear evenly.
- Used toweling from the loop 205 is fed into the roll 207 without folds or waves due to the towel straightening mechanism 69 including the spaced apart plates 70 and 75 which maintain the used toweling substantially flat at the ends thereof while at the same time providing sufficient space for the attendant to feed the toweling onto the storage roller 130 in order to load the dispenser 50 with clean toweling.
- the towel dispenser 250 shown in FIGS. 11 and 12 functions substantially the same as that just described.
- two drive rollers 340 and 350 are provided and are linked together by the sprockets 343 and 353 and the chain 355.
- the storage roller 320 is driven by the drive roller 340 while the pinch roller 360 drives the drive roller 350.
- the pinch roller 360 is of somewhat larger diameter than the drive rollers 340 and 350 to avoid wear on the drive roller 340 due to continued pressure from the pinch roller 360.
- the drive roller 350 is driven by the pinch roller 360 and in turn drives the drive roller 340 which causes rotation of the storage roller 320.
- ramps 316 and 318 for the storage roller 320 form slots which extend upwardly and forwarldy toward the front of the towel dispenser in contradistinction to the ramps 116. Operation of the stop mechanism is the same as well as operation of the used towel straightening mechanism.

Referring now to the drawings, there is shown a towel dispenser with a housing having a top wall 56 interconnected to two parallel side walls 57, each of the side walls being provided with an inwardly turned longitudinally extending flange 58. Each of the flanges 58 has a keyhole shaped slot 59 therein to facilitate mounting the towel dispenser 55 on a support surface therefor, such as a wall 60. Each of the side walls 57 further includes an inwardly turned horizontally disposed flange 61 at the bottom of the side wall opposite the top wall 56. The housing 55 has an arcuate bottom plate 65 having a curved portion 66 extending rearwardly and upwardly in the housing 55. A flange 67 extends downwardly from the bottom plate 65 intermediate the flanges 61 of the respective side walls 57 and spaced rearwardly from the front of the flanges.
As seen particularly in FIG. 10, a towel straightener 69 including a guide plate 70 having a lead edge 71, is mounted by welds 72 to the flange .61 near the rear of the housing 55. More particularly, the lead edge 71 of the guide plate 70 is spaced a small distance from the flange 58 which forms the rear of the dispenser 50. Similarly, a guide plate 75 having a lead edge 76 is fixedly mounted as by the welds 77 to the other side wall 57 and more particularly to the inwardly turned flange 61 thereof. The guide plates 70 and 75 together form the towel straightener 69 and are positioned so that the lead edges 71 and 76 respectively are parallel to the inwardly turned flanges 58 and are positioned a short distance therefrom. The lead edges 71 and 76 of the guide plates 70 and 75 respectively form a slot 80 j with the wall surface 60 on which the dispenser 50 is mounted. The slot 80 has a relatively small transverse extent in comparison to its longitudinal extent at the ends thereof and a large transverse extent in the center to facilitate loading of the clean toweling, as hereinafter set forth.
The towel dispenser 50 further includes a door pivotally connected by a hinge 91 to one of the side walls 57. The door 90 includes a top flange 92 constructed to fit over the top wall 56 and a side flange 93 constructed to fit over the other side wall 57. A latch 95 is mounted on the flange 93 and cooperates with the keeper 96 mounted on the side wall 57 to maintain the door 90 closed during dispensing of toweling therefrom. The door 90 is provided with a towel break or deflector 100 having a mounting flange 101 fixedly secured as by welding to the door 90 with an inwardly extending arcuate plate 103 having an abutment surface 104 thereon.
Each of the side walls 57 is provided with a rollersupport 110, only one of which will be described in detail since they are identical. The right-hand roller support (see FIG. 7) includes a flat J-shaped plate 111 fixedly secured to the wall 57 by rivets 112 and spaced therefrom by spacers 113, while the left-hand roller support 110 is directly mounted to the wall 57 (see FIG. 5). The plate 111 has an inwardly directed sinuously shaped flange 115 which supports and guides the various towel dispensing and storage mechanism hereinafter set forth. The flange 115 has a straight ramp I16 extending from the upper rear corner of the housing 55 toward the lower front corner of the housing 55, the ramp 116 leading to a rest in the form of an elbow 117 which connects the ramp 116 with a finger 118 pointing toward the front of the towel dispenser 50. An arcuate journal 120 leads from the finger 118 to a bearing surface functioning as a pinch roller guide 125.
The roll support 110 may be made of a plurality of pieces or sections or, as shown in the preferred embodiment, of one piece. The ramp 116 extends upwardly and rearwardly to the back of the housing 55 and has a rest at one end thereof in the elbow 117. The journal 120 in cooperation with the finger 118 provides rearward and vertical restraints, all as hereinafter set forth.
The segment joining the journal 120 with the bearing surface or guide provides somewhat of a forward restraint but to a lesser extent'than the rearward and vertical restraints of the journal 120.
Mounted for rotating and shifting movement along the ramps 116 of the two rollers supports 110 isa used towel storage roller 130. The roller includes a cylindrical body portion l31'with a dowel 132 extending outwardly from each end thereof to engage the appropriate segment of the flanges 115. The roller 130 is free for rotating and shifting movement upwardly along the ramps 116 from the elbows or rests 117 as used toweling is accumulated on the roller 130, all as hereinafter will be set forth.
A drive roller includes a cylindrical tubular body 141 having an abrasive covering 142, such as sandpaper, on the outer peripheral surface of the body 141. The drive roller 140 has the abrasive covering 142 thereof shorter in longitudinal extent than the tubular body 141 to provide two uncovered end portions 143 supported in the journals 120 of the support flanges 115. The drive roller 140 is, therefore, freely rotatably mounted in the journals 120 and is maintained therein by means of the vertical and rearward restraints provided by the journals and the finger 118 all as hereinbefore set forth. The diameters of the used towel storage roller 130 and the drive roller 140 are such that the abrasive covering 142 of the drive roller will contact the peripheral surface of the body portion 131 of the storage roller 130 when the dowels 132 are resting in the elbows 117 of the support flanges 115.
A pinch roller has a cylindrical tubular body 161 slightly larger in diameter than the roller 140 and has an abrasive covering 162, such as sandpaper, thereon which terminates short of the ends of the body 161 to provide uncovered end portions 163. The pinch roller 160 is shiftably and rotatively mounted on the guides 125 with the center of gravity of the roller 160 disposed above the center of gravity of the roller 140, the guides causing the roller 160 to be urged toward the roller 140 for a purpose hereinafter set forth. Each of the end portions 163 of the pinch roller 160, as best'seen in FIG. 6, forms one member of a stop mechanism 155 and has a cam 165 out from the end thereof and bent outwardly from a base 166 away from the surface of the roller 160 to form a camming surface 167 which terminates in a free end 168. A notch 170 is cut out of each end 163 to form a latch 172'on the pinch roller 160 with the latch 172 being angularly disposed about 200 from the I end 168 of the cam 165.
The stop mechanism 155 further includes a stop'pawl 180 pivotally mounted to one of the side walls 57. by a shaft 181. The stop pawl 180 is generally Y-shaped with an arcuate edge 185 interconnecting a cam follower 190 and a catch 195. The cam follower 190 is rests on the bottom plate 65 and more particularly on i the arcuate portion 66 thereof. The free end of the roll 201 is fed upwardly to form the reach 202 between the drive roller 140 andthe pinch roller 160 and over the pinch rollerand downwardly past the abutment surface 104 of the towel deflector 100 to form the reach 203 leading out of the opening between the door 90 and the flange 67 into an exposed loop 205 of toweling. The
In operation, a clean roll of toweling 201 is inserted into the housing 55 after the front door 90 is opened, as shown in FIGS. 2 and 3, the roll resting on the bottom plate 65 and more particularly on the arcuate portion 66 thereof. The free end of the roll 201 is fed upwardly between the drive roller 140 and the pinch roller 160 and over the pinch roller and downwardly below the flange 67 of the bottom plate. A loop 205 of toweling is provided beneath the bottom of the towel dispenser 50 and then the free end of the toweling is fed upwardly through the slot formed by the towel straightener 69 in contact with the spaced apart plates 70 and 75, the large opening between the plates facilitating the feeding of the free end of the toweling through the slot. The central opening between the plates 70 and 75 is sufficiently large to permit the attendant to insert his hand upwardly between the plates to feed the free end of the toweling onto and around the storage roller 130. After the feeding of the towel has been completed and the front door closed, the towel dispenser 50 is in condition for use. It is seen, therefore, that the'storage roller rests in the elbows or rests 117 of the supports 1 15 prior to the time that the toweling is wrapped therearound. When the free end of the toweling is wrapped around the storage roller 130 the effective diameter of the storage roller 130 increases causing the roller to shift upwardly and rearwardly along the ramps 116.
Clean toweling is obtained from the roll 201 by exerting tension on the loop 205 causing the pinch roller 160 to rotate in a counter-clockwise direction as viewed in FIG. 3. Since the pinch roller 160 shiftably and rotatably mounted on the'guides 125 is continually urged toward the drive roller by gravity and the towel deflector 100 positions the toweling 203 somewhat below the pinch roller, downward pulling on the loop 205 of toweling will rotate the pinch roller and force the pinch roller toward the drive roller 140 causing rotation of the drive roller in a clockwise direction. Rotation of the drive roller 140 in a clockwise direction causes the storage roller 130 to rotate in a counter-clockwise direction whereby maintaining the loop 205 of toweling 'at a predetermined size with the used toweling 206 being wound onto the roll 207 which continuously inafter less than one complete rotation of the pinch roller 160; Referring to FIG. 8 of the drawings, the position of the stop mechanism is shown just prior to initiating a cycle of the towel dispenser 50. The stop pawl 180 is in its normal position wherein'the weighted end 199 thereof has positioned the catch 195 as shown with respect to the pinch roller 160. In this position, the cam 165 has the end 168 thereof spaced from the end 192, while the catch 195 is spaced from the latch 172. Rotation of the pinch roller in a counter-clockwise di rection in response to the tensioning of the loop 205 by downward pulling thereon rotates the pinch roller from the position shown in FIG. 8 to that shown in FIG. 9. After almost 360 rotation of the pinch roller 160, the parts have assumed the position shown in FIG. 9 wherein the camming surface 167 of the cam is in contact with the camming surface: 191, thereby pivoting the stop pawl 180 in the clockwise direction. Pivoting the stop pawl 180moves the catch and more particularly the stop 197 into position to be engaged by the latch 172 to prevent further movement of the pinch roller 160 and to prevent further-feeding of toweling from the roll 201 into the loop 205 of toweling.
The stop pawl 180 achieves a considerable momentum during the rotation of the pinch roller 160 from the position shown in FIG. 8 to that :shown in FIG. 9, so that the stop pawl 180 continues in the direction of the arrow in FIG. 9 to a position wherein the catch 195 and more particularly the stop surface 197 thereof, moves in the direction shown by the arrow to be interposed in the path of the latch 172. Continued rotation of the pinch roller 160 beyond the position shown in FIG. 9 causes engagement of the latch 172 with the stop surface 197 of the catch 195, thereby halting further rotation of the pinch roller 160 in a counter-clockwise direction. Once tension has been released on the loop of toweling 205, the stop pawl 180 will swing back to the gravity biased position thereof shown in FIG. 8 due to the heavily weighted end 199 which continually urges the stop pawl 180 to the position shown in FIG. 8 away from the position shown in FIG. 9. Once the stop pawl 180 has again resumed the position shown in FIG. 6, with the latch 172 spaced from the catch 195, the towel dispenser 50 is again in condition wherein fresh toweling may be dispensed from the roll 201 thereof.
The abrasive cover 162 of the pinch roller 160, while not absolutely necessary for operation of the dispenser 50, is preferred and prevents slippage of the toweling from the roll 201 into the loop 205 after the stop mechanism 155 is engaged. Used toweling from the loop 205 is fed upwardly through the slot 80 in contact with the leading edges 71 and 76 of the straightening mechanism 69 to the rear of the housing 55 to prevent folds and waves from forming in the reach 206 of the toweling and, therefore, the roll 207 is substantially flat and is in better condition for later processing. As the roll 207 of toweling increases in size, the used towel storage roller 130 shifts upwardly and rearwardly and is guided by the ramps 116 of the roller supports 110.
Advantages of the towel dispenser 50 lie in the simplicity of construction which permits the storage roller 130, the drive roller 140 and the pinch roller 160 to be mounted without the usual bearings which may malfunction and require repair. Additionally, the stop mechanism ,155 is actuated in response to rotation of the pinch roller 160 thereby preventing excessive wear of the drive roller 140, a desirable feature which permits more consistent driving of the storage roller 130 through the lift of the towel dispenser 50. The fact that the pinch roller 160 is larger in diameter than the drive roller 140 also insures that the abrasive covering 142 will wear evenly. Used toweling from the loop 205 is fed into the roll 207 without folds or waves due to the towel straightening mechanism 69 including the spaced apart plates 70 and 75 which maintain the used toweling substantially flat at the ends thereof while at the same time providing sufficient space for the attendant to feed the toweling onto the storage roller 130 in order to load the dispenser 50 with clean toweling.
The towel dispenser 250 shown in FIGS. 11 and 12 functions substantially the same as that just described. In the second embodiment of the present invention, two drive rollers 340 and 350 are provided and are linked together by the sprockets 343 and 353 and the chain 355. The storage roller 320 is driven by the drive roller 340 while the pinch roller 360 drives the drive roller 350. In this embodiment, the pinch roller 360 is of somewhat larger diameter than the drive rollers 340 and 350 to avoid wear on the drive roller 340 due to continued pressure from the pinch roller 360. In this embodiment, the drive roller 350 is driven by the pinch roller 360 and in turn drives the drive roller 340 which causes rotation of the storage roller 320. It should be noted that the ramps 316 and 318 for the storage roller 320 form slots which extend upwardly and forwarldy toward the front of the towel dispenser in contradistinction to the ramps 116. Operation of the stop mechanism is the same as well as operation of the used towel straightening mechanism.
While there has been described what is at present considered to be the preferred embodiment of the present invention, it will be understood that various modifications and alterations may be made herein without departing from the true spirit and scope of the present invention, and it is intended to cover in the appended claims all such modifications and alterations as fall within the true spirit and scope of the present invention.
