United States Patent 3,193,070 AUTQMATIC SHOP TOWEL DISPENSER William H. Dudenhofier, Crystal Industrial Services, Inc., Box $27, Joneshoro, End. Filed July 11, 1960, Ser. No. 31,909 8 Claims. (Ql. 194-4) The present invention generally relates to a dispenser mechanism and more particularly to a shop towel dispenser which will automatically dispense a predetermined number of towels upon insertion or deposit of the same number of soiled towels.

As is well known, wiping towels or shop towels are employed by many employees in various industries and the distribution of these towels to the employees has been rather haphazard in nature which quite often results in a serious loss of the shop towels since employees do not always return the same number of towels that they receive. There previously have been machines attempting to overcome this problem and these machines have worked in certain instances to a certain degree. However, all of the machines have certain objections and shortcomings and it is the primary object of the present invention to provide an improved and novel structural arrangement for dispensing a predetermined number of clean towels upon insertion of a predetermined number of soiled towels.

It is another object of the present invention to provide an automatic shop towel dispenser which is compact in construction and will not take up an excessive floor space with the components of the dispenser being substantially maintenance free.

A further object of the present invention is to provide a shop towel dispenser incorporating features which will prevent persons from inserting foreign objects such as a screwdriver, wrench or the like into the machine for causing the machine to ope-rate to discharge a clean towel or towels.

A further object of the present invention is to provide a shop towel dispenser including a mechanism to prevent a soiled towel to be started into the machine for registering the machine or otherwise indicating that the towel has been placed therein after which the towel is pulled back through the entrance slot thereby assuring that shop towels are dispensed only when the same number of soiled shop towels are deposited.

Another very important feature is the provision of a shop towel dispenser having a vertically elevatable platform disposed therein having two stacks of clean shop towels thereon together with a discharge or dispensing assembly including a pair of needles movable in a reciproeatory manner along two sides of a generally triangu lar chain member for alternately picking up towels from the stacks and depositing them into a discharge area.

A feature ancillary to the immediately preceding object is the provision of a mechanism to move the platform upwardly for each increment of discharge movement of the discharge assembly or dispenser thereby maintaining the stop towels against pressure fingers for retaining the shop towels in position until picked up by the dispensing mechanism.

Still further objects reside in the over-all simplicity of the structure, dependability, ease of service and repair, adaptation of many possible arrangements into a compact structure together with a re'lativley low manufacturing cost as well as maintenance cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the acice companying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a front elevational view of the automatic shop towel dispenser of the present invention with the front of the cabinet being shown in open position for revealing the details of the shop towel dispensing mechanism and other features;

FIGURE 2 is a vertical sectional view of the dispenser with portions broken away to show details substantially upon a plane passing through the center of the machine;

FEGURE 3 is a detailed sectional view of the soiled towel receiving mechanism;

FIGURE 5 is a detailed side elevation with portions broken away illustrating the construction of the pick-up needles;

FiGURE 6 is a detailed sectional view taken substantially upon a plane passing along section line 6-6 of FIGURE 5 illustrating further structural details of the pick-up mechanism; and

FIGURE 7 is a detailed view illustrating the sensing mechanism for sensing the discharge of soiled towels into the machine for operation of the machine. automatically when a predetermined number of towels has been inserted.

Referring now specifically to the drawings, the numeral 1d generally designates the automatic shop towel dispenser of the present invention which includes a vertically disposed cabinet structure genearlly designated by the numeral 12 having a hingedly attached front door generally designated by the numeral 14 connected to the front open end of the cabinet 12 by a vertically disposed hinge 16 at one edge thereof. The hinge 16 may be of the piano type hinge or any other .suitable type hinge for securely supporting the door 14 in position. The shape and size of the cabinet and door may vary but preferably, the cabinet is of rectangular configuration and the door is provided with a suitable lock mechanism for retaining the door in closed position so that only authorized service personnel may have access to the interior thereof.

The shop towel dispenser of the present invention includes a shop towel dispensing mechanism generally designated by the numeral 18, a mechanism for supplying towels to the dispensing mechanism generally designated by the numeral 21) and a mechanism for receiving soiled towels generally designated by the numeral 22.

The mechanism for supplying clean shop towels which is generally designated by the numeral 2t) includes a flat shelf or platform 24 having depending peripheral flanges 26 on which there is positioned two stacks of clean shop towels 28. The center of the platform 24 is provided with a threaded sleeve or bushing 30 rigid therewith for mounting on a vertically disposed screw threaded rod 32.

For guiding the stacks of shop towels 28, the rear wall 34 of the cabinet 12 is provided with a vertical guide member 36 spaced inwardly therefrom with there being a vertical guide member 36 for engaging the rear center of each stack of towels 28. The lower end of the vertical guide members 36 are supported by a transverse structural member 38 attached to the bottom 40 of the cabinet and the upper end of the vertical guide members 38 are supported by an L-shaped bracket 42 carried by the rear wall 34 of the cabinet. The upper ends of the guide members 36 are inclined slightly forwardly as indicated by the numeral 44 so that as the towels reach the upper end of their movement, they are biased slightly towards i the front of the cabinet.

The door 14 is provided with a'pair of guide members 46 spaced inwardly therefrom which are shorter than the guide members 36 and engage only the centerportion of the stacks of towels with the upper and lower ends of the guide members 46 being inclined away from the towels as indicated'by the numeral 48. This will provide a guide mechanism for the towels substantially throughout the vertical length thereof. Disposed above the guide mem ber 46 is a transverse guide 'member Sti having anoutwardly inclined lower edge 52 together with a plurality of upstanding spring fingers 54 mountedthereon which flare slightly outwardly in opposition to the inclined por- 32 is supported by a bracket 58 attached to the bottom 40 and the bracket 58 also supports a gear box or gear transfer mechanism 60 which receives a power inputfrorn a .power shaft 62 driven by an electric motor 64 sup- "ported on the rear wall 34 by brackets 66. The motor 64 will operateto cause rotation of the shaft 62 and also.

rotation of thethreaded rod SZ'thereby elevating the platform 24 and the towels 23'thereon. The rear flange 26 1 of theplatforrn 24. is provided with .a rearwardly eXtending guide finger adjacent each rear corner thereof as designated by the numeral 68 with the finger 68 terminating in loops 70 to prevent any tilting or canting of. the platform. Also, there is a rearwardly extending finger 72 on the platform which extends horizontally and is adapted to engage the feeler plunger'74 of a micro-switch 76' illustrated in FIGURE 3.

soiled towels equal in number to the number of clean towels that it will hold. Also, the soiled towels will be disposed adjacent the frontof the cabinet so that when the door 14 is opened,.thesoiled towels will be readily available'to a service person thereby enabling the soiled towels to be easily removed. Adjacent the bottom of the cabinet there is providedan inwardly extending ledge 94 disposed over a'switch mechanism 96 having a plunger adapted to be engaged by an upturned edge 98' of the door 14- for energizing an illuminating light 109 when the door is opened thereby illuminating the interior of the cabinet for the convenience of the'person servicing the machine. v p

1 Disposed above the bracket 84 and adjacent the upper corner ofthe door, the soiled towel receivingmechanism is disposed. This mechanism includes an opening 102 in the front panel 86 of the door and the details'thereof are with a surrounding facing member 1614 on the outer surface thereof. Disposed inwardlyof the opening 102 is a horizontal mounting plate'106 having upstanding side plates Mid-rigid therewith. Extending between the side plates is a pair of lower rollers 110 and. 112 disposed closely adjacent each other but with the roller 112 being slightly above the roller 110 which is nearer the opening 102. Spaced above and in rolling contact with the rollers 11% and 112 isa pair of rollerslld and 116 respectively which are provided with shafts 118 movably receivedin vertical slots 12%) in the end plates 168 whereby the rollers 114 and 116 may move apart from the rollers 110 and 112. The rollers 114 and 116 are spring biased towards ;virtue' of a sprocket chain 126engaging sprocket gears mounted on the rear wall 34 of the cabinet so that the upward movement of the platform 24' will be stopped when the finger 72 engages the micro-switch plunger 74 thereby preventing the platform 24 from being elevated too high when the towels 28 are all removed from the platform.' The motor 64 is energizedeach time the distional resistance to movement of the towels. The fingers 78 are inclined towards the center of the cabinet and the pick up needles of the dispensing mechanism move between thepairs of fingers 78 in a manner described herein after. 1 As illustrated in FIGURE -2, the stacks of towels 28 are disposed towards the rear of thecabinet thus leaving the 128 on the ends of the rollers 11%, 112 and 124 respectively and also engaging a drive sprocket gear 13% carried by'the output shaft 132 of a combined electric motor and speed reductionmechanisrn 134'. The combined electric motor and speed reduction unit is supported on a bracket 14% carried by the front wall 86 of the door. i V

' Also mounted onth e end plates 108 is a protector plate 142 extending parallel to the rollers and including a pair of mounting plates 144 extending inwardly along the outer surface of' the end plates 1% and pivotally' supported thereon by a pivot bolt 146 and a pair of attaching brackets'148 that are pivoted tothe mounting plates 144 thus I pivotally attaching the mounting pla tes144 and protecting of the towels but which engage the towels to provide fric front bottom portion of the cabinet empty for/receiving soiled towels. A mechanism generally designated by the,

82 carried by a shielding bracket 84. The bracket 84 is attached to the front wall panel .86 of the door 14 at the lower edge thereof and to 'a transverse structural member plate 142 from the pivot point146. The plate 142, the mounting'plates 144 and the brackets 148 are all rigid with each other and the end of the mounting plates 144 rollers 112 and 116 thereby preventing complete insertion of said rigid articles in an attempt to operate the dis- 7 pensing mechanism without first inserting soiled towels.

88 at the upper end thereof. The motor 82 is provided 7' with a downwardly and inwardly inclined output shaft which extendsthrough the bracket 84 and attached to the shaft 90 is an elongated inverted V shaped plate 92 which receives the output shaft 90: within the crotch thereof. As themotor 32 isroperated, the V-shaped plate 82 will be rotated thus causing the soiled towels deposited into the cabinet to be distributed throughout the front area thereof so that the cabinet may contain a supply of The rollers and 112 are driven in the same direction so that any tendency of the towels to wrap around the roller =110willbe prevented due to. the upward movement of that portion of the roller 112adjacent the inner edge of the roller 110."; Also,' the roller 110 islarger than the roller 114.whereby the tendency of the towel will be to wrap around'the roller 110 rather than the roller 114. T1115 wrapping around-will be prevented by the movement of the roller 112. Also, the roller 112 is larger than the roller 116 so that the towel will follow the roller 112 and be picked up in turn by the larger roller 124 which also The opening 102 is provided charge the shop towels into a chute 150 which is vertically ported by the side walls of the chute 150 behind a front wall 158 thereof which is supported by brackets 16!). The outer end of the rod 156 is provided with a laterally extending arm 162 having an adjustable cam 165 thereon for engagement with the actuating arm 163 of a microswitch 164 whereby each towel deposited into the towel receiving mechanism 22 will engage the fingers 152 and cause them to move downwardly for operating the microswitch one time. The fingers 152 are either gravity urged to their normal position or spring biased to their normal position with a light spring so that the weight of the soiled towel will cause downward movement thereof thus causing the micro-switch to temporarily close while the towel is sliding off of the fingers 152. Due to the rotational speed of the rollers and the fact that the towels have to be inserted singly, the sensing fingers 152 will be moved by each succeeding towel thereby closing the micro-switch 164 each time a towel is deposited thereby registering the number of towels deposited into the cabinet.

A mechanism is provided for preventing withdrawal of the towels which mechanism is generally designated by the numeral 166 and which includes a transverse bracket 168 carrying a transversely extending mounting member 170 at the lower end thereof for receiving a plurality of downwardly extending parallel rods 172 therein. Setscrews 174 are employed for securing the rods 172 in position and the lower ends of the rods 172 are provided with pointed needles 176 which extend towards and are disposed closely adjacent to the fingers 152. The needles 176 are for engaging a towel to prevent its withdrawal after the towel has engaged with and actuated the fingers 152. This will prevent a person from inserting a towel or tying two towels together and inserting them so that the fingers 152 may be operated after which the towels may be withdrawn by pulling back on the portion of the towel still disposed exteriorly of the cabinet. The needles 176 will engage such towels and prevent their withdrawal thereby assuring that the towels cannot be retrieved once they have dropped down and operated the fingers 152. The entire receiving mechanism is mounted on the door andis movable therewith and the orientation thereof is shown in FIGURE 1 and the details of construction thereof shown in FIGURE 3.

Mounted centrally in the door 14 is a discharge chute generally designated by the numeral 178 which includes a generally horizontal bottom wall 180, a generally vertical rear wall 182 and a generally vertical front wall 184 and vertical side walls 186. The front wall 184 is spaced rearwardly from the front panel 86 of the door and includes a horizontal top wall 188 connected thereto whereby the top wall 188, the bottom wall 180 and the side walls 186 extend through an opening 190 in the panel having a peripheral fiange 192 for removing the clean towels therefrom. The clean towels may be retrieved by inserting the hand partially into the opening or tunnel formed by the walls but the generally L-shaped configuration of the discharge chute or assembly 17 8 is such that a person cannot reach up over the side walls thereof and engage the tripping fingers 152 nor can a person use a tool or the like for accomplishing this purpose since the side walls 186 extend substantially above the plane of the opening 190. Thus, the device is relatively fool-proof in that persons cannot obtain clean shop towels unless they actually deposit an equal number of soiled shop towels into the receiving mechanism.

The dispensing mechanism is shown in detail in FIG- URES 4-7 and the orientation thereof is shown in FIG- URE l. The dispensing mechanism 18 runs from the rear a link 2557 pivoted to plates 246.

to the front of the cabinet and picks up towels alternately from the top of the stacks of towels 28 and discharges them into the discharge chute 178. The dispensing mechanism is generally inclined upwardly and forwardly and is substantially triangular in shape with the rear end thereof being supported by a bracket 194 extending transversely and supported from bracket 42 and the forward end thereof being supported by a bracket 1% connected to a depending flange 1% carried by the top wall 200 of the cabinet.

The dispensing mechanism 18 includes a supporting frame 261 carrying an electric motor 202 on a transverse plate 264. The electric motor is provided with a power output pulley 2% engaged with a V-belt 208. The V belt 2% is engaged with a large V-belt pulley 210 supported by brackets 212 with there being a smaller power pulley 214 rigid with and disposed above the pulley 210 thereby providing a speed reduction unit. The power pulley 214 is engaged with a V-belt 216 which in turn encircles a large V-belt pulley 218 disposed at the forward end of the triangular frame 261.

The center shaft 222 of the V-belt pulley 218 is provided with a drive sprocket rigid therewith for driving a sprocket chain 222 which is endless in nature and which also extends over sprocket gears 224 at the rear corners of the frame 251. Thus, the sprocket gears and sprocket chain define generally a triangular path and the motor 222 is reversible so that the portions of the chain forming the sides of the isoceles triangle defined by the sprocket gears will move in a reciprocating manner towards the front and rear of the cabinet. When the chain on one portion of the triangle is moving forwardly, the chain on the other portion will be moving rearwardly and vice versa.

Mounted on each portion of the chain between a sprocket 224 and the drive sprocket carried by the pulley 218 is a needle carrier generally designated by the numeral 226. The needle carrier is attached to the chain 222 by bracket members 228 and the needle carrier includes guides 230 slidably engaging a channel shaped guideway 232. The needle carrier 226 also includes an outwardly extending flange 234 slidably engaging a rod 236 and for engagement with a stop member 238 carried by the rod 236. The stop member 238, when engaged, will operate a reversing cam 240 so that the re- Versing switch mechanism 242 of the electric motor 292 will be operated whereby the motor will be alternately operated in opposite rotational directions. Each time the needle carrier 226 moves forwardly and rearwardly, the reversing switch will be operated to assure that the motor will be alternately driven in opposite directions. A spring 244 is connected to the reversing cam 24% to assure its return to a normal operating condition.

The needle carrier 226 includes a pair of vertically disposed plates 246 pivotally supporting a needle arm 248 therebetween which has a pointed needle 250 removably attached to the end thereof and which is disposed in acute angular relation to the arm 248. A spring 252 urges the needle arm 2 .8 towards an operative or depending position for engagement with the uppermost shop towel 28. The arm 248 is pivoted to the plates 246 by pivot pin 254 and the arm 248 is operated by an abutment plate 256 pivotally connected to arm 24-8 and to The plate 156 is disposed at the leading edge of the carrier 226 for engagement with an adjustable stop mechanism such as bolt 258 carried by outwardly extending brackets 260 at the forward end of the frame which also support the rod 236. Thus, as the needle carrier proceeds towards the front of the frame, the needle 256 will be retracted above the lower edge of the plates 246 for assuring discharge of the shop towel into the discharge chute 178.

As will be apparent from the drawings, the needle carriers 22:: move parallel to the projecting fingers 78 so that the needles will engage theshop towels 28 interguide members as which were removed;
