Definitions

  • ABSTRACT A coin handling system for transferring coins pneumatically from a bus fare box to stationary coin processing equipment in which the coins are sorted according to denomination and delivered to a compartmented vault. The vault is later removed from the equipment and transported to a bank or other counting facility for further coin processing.
  • the system includes the bus fare box and a hose having a probe on one e nd designed to interconnect a fare box with the coin processing equipment.
  • actuation of a ring on the probe causes coacting tubes on the probe and fare box to align their ports and thereby provide an open avenue for coins to flow from the fare box into the probe and hosefSimultaneofisTy, ring actuationcafises a vacuum pump in the equipment to create a vacuum at the probe-fare box ports. This vacuum creates an air stream which lifts the coins into the open ports and carries the coins through the hose to the coin processing equipment. Upon arrival there, the coins are slowed down to minimize mutilation and then sorted according to denomination and deposited in separate compartments in the vault.
  • Both mechanical and electrical operating locks must be activated to open the vault door. As the vault is being removed, a cover on the vault automatically closes the openings through which the coins initially dropped into their respective compartments, thereby safeguarding the vault contents. To provide high security to the system, multiple mechanical and electrical locks and interlocks are used throughout the system and with the individual system components.

  • the invention described herein relates to coin handling equipment and more particularly to an improved pneumatic system for transferring coins from a vehicular fare box to a stationary vault located alongside the vehicle.
  • Each vault must be separately handled by the counting room personnel because access to the coins is acquired only by the use of an especially designed fourway key which unlocks the vault cover. After the coins are dumped in a coin sorter and sorted, the separate coin denominations must be bagged or otherwise packaged for delivery to a bank.
  • a high security coin handling system which pneumatically transfers coins from a fare box to a centralized coin processor at high speeds without mutilating or otherwise defacing the coin surface.
  • the coin processor sorts the coins according to denomination during the process and deposits them in a vault for later removal to a bank or other depository.
  • the mechanism used for transferring the coins includes a probe which connects the fare box to a hose running to the coin processor.
  • Electrical circuits and a vacuum system incorporated in the complete coin handling system control the admission of air to the fare box for lifting the coins into the probe and hose and for carrying the coins to the coin processor which sorts the coins according to denomination prior to discharging them to separate compartments in a vault.
  • the electrical circuits and vacuum system further control the operation of components in the coin processor which decelerates the coins and sorts them before delivery to the vault.
  • a number of interlocks associated with the various operating components provides a high degree of security to the overall coin handling system.
  • An object of the present invention therefore is to provide a new and unique high security coin handling system which transfers coins without manual handling from a bus fare box to a centralized coin processor which sorts the coins by denomination and stores them in a compartmented vault to await transportation to a bank.
  • Another object of the present invention is to provide a coin handling system capable of transferring coins to a coin processor at a high velocity with subsequent deceleration without coin mutilation prior to deposit in a coin processor vault.
  • Still another object of the present invention is the provision of a modified fare box incorporating features which preclude accessibility to coins therein during normal vehicle operation.
  • Another object of the present invention is the provision of a high-security probe designed for coaction with the bus fare box for effecting transfer of coins to a centralized coin processor.
  • Another object of the present invention is the provision of electrical and pneumatic control systems for controlling the transfer of coins from a bus fare box to a coin processor and for imparting a high degree of security to the overall coin handling system.
  • Still another object of the present invention is the provision of an improved design of vault for safeguarding coins after sorting according to denomination.

  • the pedestal or base of the fare box disclosed herein is equipped with a vacuum chamber which holds coins deposited therein by passengers during bus operations, rather than a vault of the type used in the prior art.
  • the primary objective is to transfer coins and tokens without mutilation from the bus fare box to a vault in a coin processor 22 efficiently while maintaining the maximum degree of security to help assure that all fares collected will eventually reach a bank or other depository.
  • a pneumatic system is used for this purpose.
  • the system includes a vacuum pump 23, FIG. 2, which draws a vacuum on the fare box and thereby causes in-rushing air to move coins at a high velocity from fare box 21 through hose 24 to an interconnecting coin slowdown chamber 26. After deceleration, the coins are dumped into a coin feeder 27 and from there, on to a sorter 28 (both shown in FIG. 2) which separates coins according to denomination, prior to dropping them into a vault for later removal from the coin processor.
  • a probe 30 on the end of hose 24, which is used for connecting the fare box to the cointransferring hose 24, is parked in a housing 31 attached to the side of the coin processor.
  • the probe is locked in place by a mechanical locking device which is electrically operated and can be withdrawn only upon insertion of a magnetically coded card into a switch located in the housing. Action of the switch energizes certain circuits, hereafter described, which permits removal of the probe from the housing.
  • the probe is designed to be manually inserted in a complementary opening in the fare box for withdrawing the coins by vacuum and transferring them to the slowdown chamber 26 in the coin processor.
  • the probe 30 of FIGS. 5 and 6 is centered in housing 31 by aligning and inserting probe locating pin 32 in a locating pin hole 33.
  • the probe body rests in cylinder 34 supported by the housing, and is designed to be locked inthe housing by a probe pawl 36 which moves into notch 35 on the locating pin thus precluding probe withdrawal from the housing.
  • a commercially available card key lock having an integral switch 45 is mounted on the housing side wall. the lock and therefore the switch, is actuated by a card key of the size and form of a conventional credit card but the card is equipped with small thin magnetic shims hidden in the card and positioned therein according to a predetermined code.
  • switch 45 contains magnetic shims which are compatible with the code in the card key so that upon insertion of the card key in slot 47, the switch 45 is actuated to a closed position; thus energizing solenoid 38.
  • the switch further is spring loaded, thus requiring the card to be held against the spring until the probe is removed from its housing. If the card key is only partially inserted or the wrong card used, the magnetic shims-in the card key and card key lock magnets will not have their polarities aligned or will be of different polarity respectively and the switch therefore will not close.
  • Solenoid 38 which is energized by switch 45, includes an armature or plunger 40 connected to pawl 36 which moves about pivot point 37.
  • Solenoid plunger movement causes corresponding displacements in pawl 36 and it therefore moves into and out of notch 35 for either locking or unlocking the probe in housing 31.
  • the plunger is biased downwardly by spring 42, so that when the solenoid is deenergized, spring 42 pulls the plunger downwardly, pawl 36 pivots about pivot 37 and the upper edge of pawl 36 engages the notch to hold the probe in a locked position in the coin processor.
  • the solenoid When the solenoid is energized, the solenoid coil pulls the plunger upwardly and pawl 36 pivots out of engagement with notch 35, thereby permitting removal of the probe from the housmg.
  • a third switch in the housing, switch 54, is normally open when the probe is parked in housing 31. Upon probe withdrawal, the switch button moves outwardly, switch 54 closes and completes a circuit to start motor 34 for vacuum pump 23.
  • switches 45, 46, and 54 are actuated when the probe is in the parked (locked) and unparked (unlocked) positions.
  • switches 45, 46 and 54 The function and circuit operation of switches 45, 46 and 54 is shown in FIG. 19 as follows: 208 volt, 3-phase power is supplied to the motor windings. By connecting across one phase and ground, 120 volt AC is made available at terminals A-B. As the card is inserted in slot 47, card key switch 45 closes to complete a circuit through the coil of probe lock solenoid 38. The solenoid plunger moves upwardly, carrying pawl 36 with it to unlock the probe and simultaneously permit switch button 44 to move outwardly and transfer switch 46 to contact 50. When in this position, relay 51 having a time delay of -20 seconds, is energized for the following reason.
  • switch 45 opens to de-energize solenoid 38 whose spring 42 then 'moves probe pawl 36 to the probe locking position even though the probe has been withdrawn. It is not necessary to again insert the card when the probe is replaced in the housing since upon replacement, the
  • FIG. 19 further shows that as the card key is removed and switch 45 opens to de-energize solenoid 38 and transfer switch 46 from contact 50 to the position shown, power is then applied to relay 53 since removal of the probe automatically closes switch 54.
  • the application of power to relay 53 transfers switch 53 to contact 55 and line voltage is applied to magnetic starting coil 56 for vacuum pump motor 34.
  • the coil pulls in contactors 57, thus starting the vacuum pump motor 34 which provides the required vacuum in the system for coin removal from the vacuum chamber as described hereafter.
  • switch 54 opens, relay 53 and starting coils 56 are de-energized and the vacuum pump motor stops running.
  • the system With the probe removed from its housing 31 and the circuits conditioned as described above, the system is set for withdrawal of coins from the fare box vacuum chamber. At this time however, neither electric power nor a vacuum is applied to the probe, even though the vacuum motor is running, because valve 227 in vacuum pump inlet 225 is in the open position. They are temporarily withheld for the purposes of security until the probe is actually inserted in the fare box vacuum chamber.
  • the probe serves as a control agent and an interface coupler when inserted and locked in the vacuum chamber. Except for starting the vacuum motor, it controls the application and removal of vacuum from the system and most electrical components used in the system operations.
  • the probe further provides accessibility to the fare box coins and facilitates their transfer from the fare box to the hose for delivery to the vault in the coin processor 22.
  • the probe specifically shown comprises a handle 60 supporting on one end, a pair of concentric cylinders or tubes 62 and 64 adapted for insertion in the fare box vacuum chamber, and a coupler 66 on the other end for removably coupling the hose to the probe body.
  • the arrangement used for supporting probe inner tube 62 from the handle 60 includes a block 108 attached to the handle by screws 110.
  • the bottom side of block 108 is attached to a stationary ring 68 which includes a flange 70 and a central bore through which an end of stationary inner tube 62 projects.
  • Set screws 72 extend through the flange and inner tube 62 for preventing relative movement between the inner tube and stationary ring 68.
  • a rotating ring 76 encompasses inner tube 62 and includes an axially directed portion 78 which extends over stationary ring 68 a distance sufficient to prevent insertion of a tool which might be used for prying the rings apart for ultimately gaining access to coins in the fare box.
  • the probe is designed to sense the continuity of electrical circuits in the system which operate components serving particular functions.
  • conductors extending from the coin processor 22 run the length of the hose and are brazed or otherwise secured to a conductive ring 80 mounted in the end of hose coupler 66.
  • An insulator 81 located in stationaryring 68 carries a pair of contact buttons 82 biased outwardly by a spring therebetween.
  • the outermost button is in contact with a conductor ring 83 having conductive and non-conductive sections mounted on the inner face of rotating ring 76.
  • Rotating ring 76 also carries a pair of contact buttons 84, 85 biased outwardly by a spring 86.
  • button 85 is constantly in contact with the exposed surface of the fare box to sense infinity or ground conditions when the rotating ring 76 is turned during the coin removal operation.
  • One of the more important security features in the system includes the arrangement for safeguarding coins in the vacuum chamber and making them inaccessible to anyone at any time, including the time during which the coins are transferred from the vacuum chamber to the coin processor 22. It is obvious that the probe access opening in the fare box vacuum chamber must be closed at all times except when coins are being transferred to the coin processor. Likewise, the opening into the probe must always be closed except during the coin transfer process.
  • the construction used for imparting a high degree of security to this part of the system includes permanently mounting the inner tube 62 in stationary ring 68 and thereby making it immovable.
  • outer tube 64 encompasses the inner tube and is at-.
  • Both the inner and outer tubes 62 and 64 respectively contain elongated openings or ports 90 and 92. Since inner tube 62 is stationary, port 90 always faces downwardly toward coins in the bottom of the fare box vacuum chamber. Port 92 on outer tube 64 faces upwardly and is rotated into alignment with port 90 as ring 76 is rotated to a port open position during the time the probe is located in the vacuum chamber for removing coins.
  • Outer tube 64 is equipped with a slot containing an axially extending key 94 having a pair of projections 96 and 98.
  • Projection 96 fits into a groove milled in the inner surface of rotating ring 76, so that as ring 76 is manually rotated, it carries outer tube 64 with it thereby moving its port 92 into alignment with inner tube port 90.
  • the corresponding tubes 170 and 172 in the fare box vacuum chamber are similarly arranged.
  • Outer tube 170 is stationary and its port 186 faces the coins.
  • Inner tube 172 is rotated to align its port 188 with port 186.
  • projection 98 on key 94 engages slot 190 on tube 72 so that as rotating ring 76 is turned, the projection 98 causes the inner tube to rotate and achieve alignment of ports 186 and 188.
  • the aligned ports and 92, 186 and 188 face coins in the bottom of the fare box and thereby provide an avenue for flow of coins into the hose.
  • air is drawn at a high velocity through fare box openings and into the probe aligned and open ports, it causes coins in the fare box to be air lifted through the ports in the probe and vacuum chamber tubes and into the hose for passage to the slowdown chamber 26 on coin processor 22.
  • the coupler 66 on the other end of probe 30 is designed to couple hose 24 to the probe body.
  • the coupler includes a machined cylindrical element 99 having internal grooves 100 which receive complementary ribs 101 formed on the hose outer surface.
  • the hose further is firmly bonded by cement to the coupler, to provide the strongest joint reasonably possible.
  • a stop 102 abuts the end of inner tube 62, thus limiting its forward travel into the probe body.
  • the coupler includes a bore 104 designed to receive a conductor welded or otherwise secured to the hose coupler conductor ring 80 which is attached to the coupler by set screws.
  • Probe handle 60 is connected to stationary ring 68 by a block 108 and screws 110. The screws connecting the other end of the block to the stationary ring 68 are not shown.
  • a lock housing 112 attached to block 108 by screw 114 contains a four-way hose coupling lock 116 having a lock blade 118 of eccentric shape for engaging slot 120 extending around the coupling periphery.
  • the function of lock blade 118 which is activated by key 122, is to removably hold hose coupler 66 on inner tube 62. Since the hose 24 can be decoupled from the probe, decoupling is resorted to only in those emergency situations where the probe for any reason cannot be removed from the fare box.
  • decoupling can be effected by key 122 which rotates the hose coupling lock plate 118 out of its groove 120 in the coupling. This action releases the coupler and its connected hose from the probe and thereby permits an operator to drive the bus away from the coin removal service station and extract the decoupled probe at a more convenient time.
  • a new probe is locked on the end of coupler 66 by actuating lock 116 and moving the lock blade 118 into a locking position. The coin removal process can then be resumed without disruption to the bus servicing operations.
  • the conventional bus fare box 21 includes a coin collection chamber into which passengers deposit coins, a coin registering mechanism (not shown) and a pedestal which supports these two mechanisms.
  • the pedestal illustrated does not include the conventional vault, but rather, comprises an outer casing enclosing a vacuum chamber assembly 152 into which coins drop from the fare box registering mechanism.
  • the pedestal is closed on all sides and is adapted to be bolted to the floor of a bus. It further includes a slidable door 154 which simply closes the opening into which the probe is inserted for withdrawing coins.
  • Air inlet openings 156 located in the sides of the pedestal permit ingress of air to the vacuum chamber for lifting the fare box coins into the hose during vacuum pump operation.
  • the vacuum chamber assembly positioned in the casing includes a housing 158 having an escrow chute 160 through which coins drop from the fare box opening, or from the coin registering mechanism if one is used.
  • the chute is open when the bus is carrying passengers but is closed by a slidable door 162 when coins are being removed from the vacuum chamber so as to limit the flow of air through pedestal air inlets 156 to the vacuum chamber.
  • As the coins leave chute 160 they are directed by internal baffles 163 toward the curvilinear base 164.
  • the base is perforated as shown to permit the ingress of air from pedestal openings 156 for lifting coins into the probe and hose for delivery to the island unit.
  • high and low level detector switches 165 and 166 are used for detecting the presence of unremoved coins. Should either of these switches, FIG. 19, be closed by a coin, a relatively negative voltage is applied to the base of transistor 300 thus negating the operation of transistor 356, with the result that the coin chamber release solenoid is not energized thus preventing removal of the probe.
  • the remedy is simply to rotate probe ring 76 clockwise then counterclockwise to modulate the air stream and dislodge a coin or coins in contact with level switches 165 or 166.
  • a pair of concentric tubes 170 and 172 similar to the probe tubes 62 and 64 are mounted in the vacuum chamber assembly as shown in FIGS. and 9 through 13.
  • the purpose and function of the set of concentric tubes 62 and 64 on the probe and concentric tubes 170 and 172 in the vacuum chamber is to establish aligned openings or ports through which coins pneumatically move from the vacuum chamber to the hose for delivery to coin processor 22.
  • one tube of each set is stationary and its port always faces the coins.
  • the other tube of each set is rotated by probe rotating ring 76 when the probe is inserted in the vacuum chamber.
  • the ports on all four tubes are aligned, an avenue is provided for movement of coins from the fare box through the probe to the hose for delivery to the island unit.
  • the tubes rotated by rotating ring 76 can only move when certain mechanical and electrical conditions in the circuitry are satisfied.
  • the ultimate purpose for this kind of arrangement is to safeguard the coins in the vacuum chamber. The coins cannot be transferred unless tube rotation takes place to align their ports.
  • the outer tube 170 extends through and projects beyond the front and rear walls of the housing. It is welded or otherwise fixed to plate 174, which in turn is attached to the housing wall by a spacer 176 and bolt 178.
  • the plate 174 includes a centering hole 180 for receiving the locating pin 32 when the probe is inserted in the vacuum chamber.
  • a pair of contacts 184 and 185 are secured in the face of plate 174.
  • the inner tube 172 is supported and rotates in outer tube 170.
  • A'notch 190 located in the top of tube 172 is engaged by the driving projection 98 of key 94 mounted on probe outer tube 64 (FIG. 5).
  • rotation of ring 76 causes key 94 to simultaneously rotate tubes 64 and 172 to the port alignment position to provide an avenue for the flow of coins from the vacuum chamber into the hose.
  • FIG. 10 which shows the back side of the vacuum chamber, as aforementioned, the outer tube projects beyond the wall of housing 158.
  • a plate 189 having an arcuate slot 191 is mounted on the closed end of tube 170.
  • Connector 192 extends through the slot and is attached at one end to the back wall of the inner tube and at its outer end to an escrow door drive arm 194 which is connected to the slidable escrow door 162 through bell crank 196.
  • connector 192 rides upwardly in the arcuate slot, thus moving the escrow door drive arm upwardly and, through the action of the bell crank, causes the escrow door to close. This action blocks the opening through which coins drop and prevents the ingress of air at the top of the vacuum chamber and provides for maximum coin lift at the bottom thereof during the coin removal process.
  • a look pin solenoid 198 mounted on the back of the vacuum chamber includes a plunger 200, a flexible coupling spring 201 and spring 202 biases the plunger in a downward direction.
  • the end of the plunger is adapted to move through a hole in the pedestal outer tube and into engagement with a notch 203 formed on inner tube 172,.
  • the notch is in alignment with the plunger when the outer tube is in a closed position.
  • This locking arrangement of plunger 200 in notch 203 constitutes a security device since it precludes anyone from reaching in the open end of tube 170 and turning the inner tube 172 to a port open or coin accessible position when the probe is not in the pedestal.
  • a further security feature resides in the use of a heat treated steel cover plate 207 which surrounds the solenoid plunger 200. Should a hole be cut in the pedestal wall for the purpose of using a tool to lift the plunger to permit rotation of tube 172 to a port open position, the cover plate would be effective in resisting such action since it bars access to the plunger.
  • the inner tube has two notches 204 and 206 in its outer surface, FIG. 13, which serve the following purpose.
  • the solenoid is energized and the plunger 200 is withdrawn from its locked position in notch 190.
  • the solenoid is de-energized as described hereafter, and the spring biases the end of the plunger downwardly through the hole to ride on the outer edge of the pedestal inner tube 172.
  • the plunger falls into notch 204 and prevents rotation of the ring back to the 0 position in the event that probe removal was desired without going through the complete coin withdrawal cycle.
  • an actuating lever 208 is slidably attached to the back of the pedestal plate 189 by a pair of screws 209 which allows loose movement of the lever vertically.
  • the upper end of lever 208 is arranged to move beneath a lip 199 on the solenoid plunger 200 to move the plunger out of locking engagement with the inner tube 172 and thereby permit rotation of ring 76 and tubes 64 and 172 to a probe withdrawal position.
  • Such vertical movement of lever 208 is accomplished by a fourway lock 210 mounted on the housing.
  • a cam-like member 212 mounted on the lock is arranged to be rotated as the key is turned, thus moving it into engage ment with the bottom edge 213 of lever 208.
  • Lever 208 then rises, and its upper surface engages the solenoid plunger lip 199 to move the plunger upwardly out of contact with the tube. This action releases the mechanical operating components and thus permits withdrawal of the probe from the pedestal.
  • a commercially available vacuum switch 216 set for about 4 inches mercury carries an open-ended conduit 218 which extends through the outer tube 170 for exposing the vacuum switch to the pressure prevailing in the vacuum chamber.
  • the openended conduit normally sees only the walls of tube 170 and cannot sense the true pressure in the vacuum chamber.
  • a hole 219 drilled through the wall of tube 172 is located in a position to align with the open-ended conduit 218. As the tube 172 is rotated by ring 76 to the l5 position, the hole 219 is aligned with conduit 218 which permits accurate sensing of the pressure in the vacuum chamber. In the event that vacuum chamber pressure is less than 4 inches mercury, switch 216 will not close and the system will not operate, as described later in relation to FIG. 19.

  • Air surrounding the pedestal is drawn through the pedestal air inlets 156 by the suction established at the ports to the probe.
  • the configuration of the vacuum chamber and the pedestal causes the air to flow downwardly, then upwardly through the perforations in chamber base 164 and in so doing, lifts the coins into the open ports on the probe for transfer by the hose 24 to the coin processor 22.
  • the velocity of air flowing through the perforations and into the probe must be sufficiently great to both overcome the weight of the coins and to accelerate them to that speednecessary to reach the slowdown chamber 26 and to overcome the frictional and other forces presented by the hose inner walls and the tumbling coins.
  • the coins move at a high speed in the hose, they must decelerate within a short distance without harmful effects to the coins, if efficiency is to be derived in the system.
  • mutilation takes the form of multiple indentations on the coin surface roughly the size of a pinhead or less.
  • Coins recycled about 25 times in a system such as that disclosed herein, and slowed by striking a barrier result in surface mutilation so extensive that the coin markings are obliterated.
  • a coin slowdown chamber 26 in the coin processor 22 As shown in FIG. 2, the end of hose 24 is attached to the end of chamber 26 into which both the coins and coin carrying air are discharged.
  • the chamber is positioned at an angle to the vertical to assure having the coins come to rest in the bottom thereof.
  • the slowdown chamber contains a perforated cylinder 222 which serves to rapidly vent the coin carrying air through outlet 224i, noise mufler 224a and a pipe leading to the vacuum pump inlet.
  • the suction drawn by the vacuum pump establishes an area of reduced pressure in the slowdown chamber thus effectively diverting the air outwardly and consequently removing all the force which acted to propel the coins at a high speed.
  • the air changes its direction of travel prior to discharge from the perforated cylinder 220, it cuts across the fowardly moving coins and this action also helps to reduce the coin velocity. As air leaves the cylinder, the coins fall by gravity to the bottom of the chamber.
  • the vacuum pump 23 has two inlets, the first through inlet 225 which is controlled by a bleeder air solenoid 226 and an air valve 227.
  • the other inlet is through the fare box vacuum chamber and ports in probe 30, hose 24 and the slowdown chamber 26.
  • air is drawn through the inlet 225 because probe ring 76 has not been rotated and the probe ports are closed.
  • the bleeder air solenoid is energized to close air valve 227 and suction is thereby shifted from inlet 225 to the probe ports.
  • a escrow door 228 hinged to the bottom of the slowdown chamber is actuated by air cylinder 229 and its associated linkage 230, to an open position to discharge the coins into coin feeder 27 when the probe is relocated in housing 31.
  • the slowdown chamber is of relatively simple design, it is extremely effective in rapidly decelerating the coins and without mutilating the coin surface.
  • the coins move at approximately 80 mph in the hose and the normal time for emptying a fare box, including time delays incorporated in the circuitry, is less than 30 seconds.
  • Coin slowdown and-air venting occur simultaneously.
  • an assortment of each of unused quarters, tokens, dimes, nickels and pennies were cycled through the above-described system 200 times. Upon examination of the coins after the last cycle, it was difficult ot visually determine any marks, burrs or other indentations in the coin surface.
  • the coin feeder 27 serves to transfer coins between the slowdown chamber and coin sorter 28.
  • the feeder simply comprises a steel trough which is vibrated by a magnetic vibrator 231 to meter the coins on to the coin sorter at a predetermined rate.
  • the coin sorter 28 is one of many different commercially available types.
  • the sorter comprises a base 232 having upstanding stanchions 234 which support a number of coin receiving trays 236.
  • Each tray has openings in its surface of different diameter for permitting coins of different denominations to fall therethrough.
  • the uppermost tray has openings of a size sufficient to permit all coins except the largest size, in this case quarters, to fall through the openings and on to the next lower tray.
  • That tray has slightly smaller sized openings and permits nickels, pennies and dimes to fall through while retaining tokens.
  • the next tray retains nickels, and so on, until all coins have been sorted according to denomination.
  • the trays may be positioned substantially end to end or at right angles to each other and at different depressions from the horizontal.
  • a separate plate 238 mounted below each tray returns the coins which have fallen through openings in the tray immediately above it, to the right as shown in FIG. 2.
  • the mass of coins then move in the reverse direction to again isolate the next size larger coins, and so on until all coins have been sorted.
  • a commercially available magnetic vibrator 240 anchored to the coin processor base is attached to the tray assembly. It vi brates the tray assembly at 3,600 c.p.s. to continually keep the coins in motion and moving toward the end of each tray.
  • the arrangement of trays is such that the coins separated according to denomination fall through pipes 242 directly into separate compartments in a vault 244.
  • the vault 244 is mounted on rollers 245 which move on a track in the coin processor.
  • the vault 244 is constructed of heavy steel plates and is internally divided into compartments for the different coin denominations.
  • a slidable plate attached to the underside of the top of the vault holds a toothed bar which projects above the top surface.
  • a toothed gear, not shown, on the coin processor housing engages the toothed bar when the vault is in the coin processor. As the vault is pulled outwardly, the gear remains stationary and its teeth pull the toothed bar and the connected cover to a position which closes the openings through which coins dropped into the compartmented vault.
  • That portion of the coin processor which houses the vault comprises heavy steel plating including a locked security door 246 having a door handle 247.
  • the door is designed to be opened by two custodians, each of whom have a different key for the two vault locks, as described hereafter.
  • the construction for locking the security door 246 consists of moonshaped discs 260, 262 and 264 mounted on the inside of a framing member for the door. Each disc has a flat side 266 which when moved vertically, is in a door unlocked position. The round portion on each disc extends across the door to lock it in position.
  • Disc 260 is provided with a notch 268 engageable by a latch 270 which when engaged, holds the door in a locked position.
  • a four-way lock 272 having an eccentric disc, not shown, moves the latch out of notch 268 when a key is inserted in the lock and turned. This action merely moves the latch to a door unlocked position.
  • the lever arm 274 on disc 260 is used for manually rotating the disc after the latch 270 is moved out of notch 268.
  • a longitudinally extending bar 276 interconnects discs 260, 262 and 264 so that upon rotation of lever arm 274, all discs turn simultaneously.
  • Disc 262 is likewise equipped with a notch 278 and a latch 280 which is operated by a solenoid 282 and plunger 283.
  • Latch 280 is pivoted at 286, the arrangement being such that when the plunger moves upwardly to disengage latch 280 from notch 278, switch 284, FIG. 17, also is closed.
  • solenoid 282 is energized from a remote source on the coin processor thus requiring two custodians to carry out the vault door unlocking operation.
  • a four-way lock 290 located in housing 31, FIG. 4, energizes solenoid 282 which moves latch 280 out of locking engagement with disc notch 278.
  • the lock 290 contains a cam 292 which depresses switch button 294 and closes security switch 296' located in the circuit, FIG. 19, to the vault door. Closure of switch 296 contacts also energizes solenoid 282 which moves latch 280 out of notch 278.
  • a second custodian using a different four-way key for lock 272 disengages latch 270 from notch 268 in disc 260. Since both discs are now free to turn, a custodian rotates handle 274 thus permitting bar 276 to move upwardly and rotate the discs to a door unlocking position.
  • switch 298 on the door frame closes and completes a circuit to a red flasher 288 mounted on top the coin processor 22. Flashing of the red light shows that an operation involving the security vault is under way.
  • a switch 299, FIG. 19, mounted on the back wall of the coin processor, which had been held open by the vault pressing against it closes and completes a circuit to the flasher 288.
  • the door permitting access to the coin processor section containing the coin sorter also actuates a switch 295 on the door frame to a closed position when the door is opened. Also, the door permitting access to the coin processor section containing the vacuum pump and other components actuates a switch on the door frame to a closed position when the door is opened.
  • the door switches Since it is essential for the purposes of security that the system operator will be aware of any activities involving the doors in the coin processor 22, the door switches have been incorporated in the flasher circuit to cause operation of the flasher should any door be opened. If any of switches 295 through 299 be closed, the circuit to the flasher will be closed and it will flash to show that one or more of the doors to the coin processor are open or that the vault has been removedfrom the system.
  • the components are initially considered to be in a static condition, i.e., volt, 60 hertz, single phase power is available at the coin processor 22 input terminals A-B, 208 volt, 3-phase power is available for the vacuum pump motor, and 12 volt, DC. power is supplied to the fare box pedestal from the bus battery but none of the components are operating.
  • the electrical circuit of FIG. 19 shows the static condition. At this time, the vault is positioned in the coin processor, the doors are closed and locked, the vacuum motor, coin feeder and coin sorter are in an off" condition and the probe is parked in its housing 31 on the coin processor.
  • the probe 30 is removed from its position in housing 31 and inserted in the fare box. Probe removal starts the vacuum pump.
  • the rotating ring 76 is rotated to its full position to open the probe ports and air drawn into the vacuum chamber, lifts the coins into the probe and connected hose 24 for delivery to the slowdown chamber 26 on the coin processor.
  • the coins come to rest and the air is vented from the chamber.
  • the probe is withdrawn from the fare box, replaced in its housing and the vacuum pump stops.
  • the coins are dumped into a coin feeder, and metered on to acoin sorter which sorts the coin according to denomination prior to depositing them in separate compartments in a vault.
  • the vault is removed from the coin processor, emptied at a bank or money counting room, replaced in the coin processor and the doors locked.
  • the system is again in a static state and conditioned for the next coin removal operation.
  • probe 30 is removed from housing 31 by first inserting the card key which closes switch 45, FIG. 3.
  • Probe lock solenoid 38 is energized and upward movement of its plunger moves pawl cam 36 downwardly to unlock the probe and simultaneously transfers switch 46 to contact 50, FIG. 19.
  • Closing of contact 50 completes a circuit through time delay relay 51.
  • This circuit arrangement is employed to require full replacement of the probe in its housing. If it is not fully inserted within seconds after removal from the fare box pedestal, relay 51 closes switch 51 which sounds siren 52 until the probe is re-housed properly.
  • the probe can be removed from housing 31 only so long as the card key keeps switch 45 closed and solenoid 38 energized.
  • switch 45 opens and solenoid plunger spring 42 moves switch 46 to its initial static position thus opening the circuit to time delay relay 51.
  • probe switch 54 automatically closes and power is applied to solenoid 53 which transfers switch 53' to contact 55. This action applies line voltage to magnetic starter 56 which closes contactors 57 to start vacuum pump motor 34 in the coin processor.
  • Vacuum pump 23 suction is taken through inlet 225 and is not applied to the probe end until the probe is actually placed in the fare box. This is accomplished by keeping the bleeder air valve solenoid 226 deenergized thereby permitting air to be drawn into the vacuum pump from the parallel source. At this time, the probe tubes are closed for security purposes and since a slight vacuum is present at the probe, tube closure prevents ingress of foreign material into the probe.
  • lock 171 on the end of probe outer tube is pushed on to four-way key 173 which is permanently installed inside the vacuum chamber.
  • the key 173 unlocks the probe inner tube 62 from the outer tube 64 and permits the ring 76 to be rotated 15 and intitiate turning of outer tube 64 counterclockwise to align its coin receiving port 92 with the inner tube port 90.
  • a 2.7 KC signal is applied to the pedestal circuit from the components in the coin processor. Signals having other characteristics may be used. As indicated in FIG. 19, 120 V AC supplies the circuit in the lower part of the diagram.
  • the secondary winding 302 of a step-down transformer 304 furnishes 24 V AC to a full wave rectifier bridge 306. Diodes 308 and 308a rectify the AC voltage from the transformer to provide pulsating DC power to the circuit.
  • the 2.7 KC signal is generated in the oscillator circuit including transistors 310, 312 and 314.
  • the oscillator is of a conventional type which provides an AC signal from collector 316 to the capacitors 318 and 320 and potentiometer 322.
  • Capacitor 324 is a coupling device for passing the AC portion of the signal and withholding the DC. These components coact with transistor 312 which serves as a buffer amplifier to maintain oscillator stability.
  • the amplified signal from this buffer stage is passed through coupling capacitor 326 to the final amplifying stage of transistor 314.
  • This amplified signal is transmitted through the sheathed cable 330 to the probe inserted in the fare box pedestal. Since the ring 76 has not rotated off the 0 position, the signal is made available through the slip ring conductors 80 and 83 and their respective contact buttons to button 85 which bears against plate 154 in the pedestal.
  • the 2.7 signal is transmitted through impedance matching transformer 332 to a cascaded amplifier including transistors 334 and 336.
  • the capacitor 338 and resistor 340 filters out unwanted noise and frequencies.
  • a relay 342 and diode 344 are connected to the collector of transistor 334 and when the relay is energized as a result of transistors 336 and 334 conducting, switch 342' closes which in turn energizes relay 346 and its switch 346 closes. Closing of 346' energizes the escrow air cylinder 348 and the air bleeder solenoid 226 to provide a vacuum at the probe of 10 inches to 12 inches mercury.
  • time delay relay 350 is energized to close switch 350 and the coin feeder vibrator 231 and the coin sorter vibrator 240 are energized and become operative.
  • the small hole in the outer tube of the probe aligns with the vacuum switch 216 which senses the reduced pressure and causes its contacts to close. Since the vacuum switch is in the emitter circuit of transistor 352, the transistor conducts and its output is applied to transistor 354 which inverts the signal and applies it to the base of transistor 356 which is coupled to transistor 358 to provide a signal of sufficient amplitude to energize the coin chamber release solenoid 198. As the end of armature 200 of solenoid 198 lifts, the probe inner tube 172 is unlocked and probe ring 76 can then rotate the tube toward a port open position.
  • the capacitors 360 and resistors 362 in the pedestal circuit are used to pass only the 2.7 kc signal and filter out other unwanted frequencies.
  • the ring 76 is not moved off the 20 to 165 zone within the time of to 20 seconds set by the relay, switch 51 will close and sound siren 52 to alert the operator to continue moving ring 76. Therefore, the ring 76 must be turned to the 170 to 180 position within 10 to 20 seconds.
  • the suction drawn by the vacuum pump at the ports leading into the probe causes air to enter the pedestal air inlets 156, flow toward the bottom of the vacuum chamber then upwardly through the perforations to lift the coins into the probe and carry them to the slowdown chamber.
  • the coin level switches 165 and 166 in the vacuum chamber determine whether the probe can be removed. lf coins bridge either switch contact to the metal frame of the vacuum chamber, the probe cannot be removed for the following reason. As the probe ring 76 was initially moved from the to the l65 position, the 2.7 kc signal was no longer applied to the base of transistor 352 with the result that transistors 354, 356 and 358 became nonconducting and the coin chamber release solenoid 198 was de-energized. As indicated previously, the end of the solenoid armature of plunger 200 then rides on the peripheral edge of the pedestal inner tube 172 and falls into a notch provided on its outer surface after the ring 76 is moved from the 15 position. This locking arrangement thus precludes removal of the probe since the commitment has been made to remove coins.
  • the 35 switch 366 in the base circuit of transistor 356 closes because the outer contact button 85 in the probe ring 76 moved off the contact button 184 and senses the ground conditions in the circuit. However, if all the coins are evacuated from the vacuum chamber, transistor 356 will conduct and energize the coin chamber release solenoid 198. Should a coin remain in the coin chamber and contact one of the level switches 165 or 166, the closed circuit to the base of transistor 300 negates the operation of transistor 356, solenoid 198 is de-energized and the probe therefore cannot be removed from the vacuum chamber. In any event, the capacitor 370 in the base circuit of transistor 300 comprises a time delay device which delays the operation of transistor 356, the delay being sufficient to clear the hose of the last coins removed from the chamber.
  • the probe ring 76 can be turned to the zero degree position when level switches 165 and 166 are open and the 35 switch is closed.
  • the arrangement is such that the 35 switch contacts open before the probe can be removed, permitting the coin chamber release solenoid to de-energize and lock the pedestal port in a closed position.
  • relay 342 opens switch 342' and de-energizes 346.
  • the opening of switch 346 de-energizes the bleeder air solenoid 226 and the escrow air solenoid 348.
  • the escrow door therefore opens and the coins are dropped on to the coin feeder which meters the coins on to the coin sorter.
  • Both the coin feeder and the coin sorter magnetic vibrators 231 and 240 are operating and the coins pass from the sorter directly into the compartmented vault.
  • relay 350 After a predetermined time delay set by relay 350, usually 3 minutes, its contacts 350a open and power is removed from the coin feeder and coin sorter.
  • the circuits and equipment must be conditioned so that the hose probe is in the parked position and power to the vacuum pump motor, coin feeder and coin sorter is disconnected.
  • a custodian actuates fourway lock 290 to close switch 296"in housing 31 and cause solenoid 282 to move latch 280 out of its locked position.
  • a second key simultaneously and independently actuates lock 272 to move latch 270 from its notch 268. This action then permits the raising of bar 276 to unlock the vault door.
  • proximity switch 376 on the vault door closes and applies power to relay 378, FIG. 19, which in turn disconnects switches 375 controlling the hot power lead to the control circuits.
  • Switches 295 through 299 apply power to the flasher light during the time that the door is open or the vault removed for service or maintenance.
  • a coin handling system for transferring coins from a receptacle to a depository comprising:
  • a receptacle having a chamber for holding coins
  • a hose having means on one end adapted for insertion in the chamber recess, said means being operable to selectively establish an avenue for the flow of coins from the chamber into the hose;
  • a coin processor spaced from the receptacle and having a coin slow-down chamber therein, and means connecting the outlet end of said hose to the slowdown chamber;
  • said vacuum equipment having an outlet for discharging air to the atmosphere
  • coin conveying means located adjacent said coin slow-down chamber for receiving coins-therefrom and discharging them into said depository
  • control means connected to said vacuum equipment for controlling the operation thereof and the application of a suction at the inlet to said hose for transferring said coins to said depository;
