Definitions

  • ABSTRACT A construction adapted to receive coins, tokens and other checks for the purchase of articles or services, the construction including means for detecting fraudulent checks.
  • First and second engaging means are provided upon insertion of a check with the spacing of the engaging means being such that proper checks are supported while slugs of lesser diameter and thickness are not held so that subsequent purchasing functions will not take place.
  • a third engaging means spaced a like distance from the first engaging means provides a second means of detecting slugs that vary in diameter and thickness from coins.
  • the check carrier or other mechanism defining some of the engaging surfaces also includes sensing means which detect the presence of a washer and thin slugs to disable the purchasing mechanisms. This detecting arrangement is held out of operating position until after the aforementioned diameter check is accomplished.
  • the combination is particularly useful in a parking meter and may include means for the purchase offree time wherein the cheek carrier can he used to advance time purchasing means without the presence of a check in the check carrier.
  • check detecting means In meters and other check receiving mechanisms, it is desirable to provide means for detecting slugs, to the greatest practical extent, so that unfair receipt of goods or services will not result. Particularly in the case of parking meters and other structures which are necessarily limited in size and must be economically produced, check detecting means of a complex nature are unsuitable. For cost purposes and to avoid a mass of parts, attempts have been made to develop uncomplicated detecting means; however, the screening ofspurious checks with prior art arrangements is still limited.

  • FIG. 9 is a perspective view of at detecting structure and associated pawl means adapted to be used in combination with the structure of FIG. 8',
  • FIG. 10 is a front elevational view of a winding ring and check carrier means adapted to provide for the purchase of free time on the meter shown in phantom;
  • FIG. 11 is an enlarged fragmentary cross-sectional view taken about the line 1111 of FIG. 10;
  • FIG. 12 is a perspective view of a free time winding member utilized in the construction.
  • the construction of this invention relates to means for detecting coins, tokens or other checks when they are inserted in a parking meter, vending machine or any similar structure which is adapted to provide articles or services.
  • the detecting means are designed so that the insertion of proper checks will result in the desired operation of the machine whereas the insertion of slugs will avoid the desired operation.
  • the construction of the invention more particularly involves a means for holding checks inserted with the checks being substantially vertically disposed.
  • First and second engaging surfaces are provided with the span between these surfaces being such that slugs of less than a predetermined diameter will drop through while proper checks will be supported. Movement of the check holding means in order to initiate operation of the machine will result in the dropping of proper checks and a third engaging surface is preferably adapted to engage the checks at that time so that the checks will again be supported.
  • the span between the first and third engaging surfaces is such that fraudulent checks of lesser diameter cannot be supported at this position.
  • the invention finds particular application in parking meters wherein the third engaging surface may comprise an element in a position to operate the time winding pawl.
  • a further detecting means is associated with the pawl structure comprising feelers adapted to sense the presence of a hole in a washer as well as slugs of reduced thickness whereby the time winding pawl will not operate.
  • feelers adapted to sense the presence of a hole in a washer as well as slugs of reduced thickness whereby the time winding pawl will not operate.
  • feelers adapted to sense the presence of a hole in a washer as well as slugs of reduced thickness whereby the time winding pawl will not operate.
  • this bearing surface Upon movement of the check carrier, this bearing surface is disengaged from the bearing member to free the detecting means for movement of the feeler for sensing the presence of holes in washers and reduced thickness of slugs thereby disabling the time winding pawl. At the end of the carrier movement, the bearing surface is again engaged, so that the feeler will release any slugs or coins. This feature prevents any hangup" of checks in the coin carrier, for example, as might occur if a feeler catches on a rough coin surface.
  • the structure of this invention is also ideally suited for use in combination with means for achieving free time on a parking meter.
  • the check carrier is provided with means for engaging an abut ment means with the abutment means being opera tively connected to a time winding means.
  • engagement of the check carrier with the abutment means will operate to move the time winding means for a set amount even without the presence of a coin or token in the check carrier.
  • This arrangement is ideally suited for shopping areas or the like where short term parking is prevalent.
  • the merchants in such areas can be provided with a means for serving customers on a free parking basis as long as the customers use only the short period of time available with the arrangement de scribed.
  • the time winding operations must be initiated through the use of checks in the standard fashion.
  • FIG. 1 illustrates the front mechanism frame portion of a parking meter construction.
  • the meter carries a handle 12 and an indicator dial I6 is mounted on the meter with pointer I8 serving to indicate the amount of time purchased.
  • Coin slots are defined by the meter for purposes of receiving coins of different denominations. In some instances, a token will be utilized with the construction, and a slot separate from a coin slot could be employed. In other instances, a meter or other device may simply be designed for the insertion of a single check,
  • the slots 20 terminate behind the wall 10 and checks passing therethrough are inserted in openings 23 in a carrier 22.
  • the carrier is adapted to be rotated by means of a handle 12 and a time winding ring 24 is adapted to be moved by the carrier.
  • a winding pawl 42 is associated with the carrier for engaging teeth 31 on the winding ring when a proper check is held by the carrier.
  • a ratchet 26 defines ratchet teeth 28 which are engageable by a separate pawl 56 to prevent return movement of the carrier.
  • the mechanism for operating the pawls carried by the check carrier includes cam segments 30 which are mounted on the inner surface of the wall 10.
  • the carrier 22 is normally urged against post by means of a spring (not shown).
  • a shield 27 is attached to or formed integrally as a part of the carrier so that access through slots 20 is blocked when the carrier is moved away from the post.
  • the shield functions to prevent entry of any tool which might be used in an attempt to cause the meter to malfunction.
  • Checks inserted through the openings 20 are vertically positioned, and the structure of the invention calls for engagement of these checks with one of the set screws 32, 34 or 36. As best shown in FIG. 2, these set screws are mounted on the check carrier 22 at the back of the openings 23, and as shown in FIG. 8, a point on the edge of a check is adapted to engage one of the set screws.
  • a pin 38 is located in position with respect to each check slot 20. These pins are positioned on the bottom of each slot whereby a point on the edge of each check will engage the edge of a pin 38 at the same time as the edge is engaged with one of the set screws. Instead of pins 38, the as-cast bottom surfaces of the slots may be utilized.
  • the bottom surfaces of these slots may be formed with slots 39 terminating in a V- shaped configuration so that an unusually thin slug will fail to bridge the span to the set screws even if the slug is of the same diameter as a coin which is to be inserted in a particular slot.
  • the slots 20 are preferably dimensioned to prevent the entry of slugs which are too thick or of a diameter greater than a proper coin.
  • Vshaped notches is also possible with respect to either the set screws or the engaging surfaces 58, 60 and 62 to be described. Obviously these notches must be designed so that a coin of proper thickness will bridge a particular notch at a proper position so that the coin will extend across the spans and be suspended for proper meter operation.
  • the distance between a set screw and an oppositely disposed pin 38 is precisely determined by adjustment of the set screw so that a proper size check will automatically be suspended between a pin and screw with the check carrier in its normal check receiving position.
  • a slug having a diameter less than the diameter of a proper check the check will not be suspended and will most past the position illustrated in FIG. 8 and into a reject accepting location.
  • a rejected check may simply be collected in the regular collection box or means may be provided for returning rejected checks. The latter course is preferred from a public relations standpoint since, in some instances, a proper check may be rejected, for example, if the user should accidentally place a dime in the nickel slot.
  • additional slots 40 may be employed for discharging rejected checks. These slots are shown in alignment with the slots 20, and ifa check should fall down from the position shown in FIG. 8, any suitable guide may be provided for directing the checks outwardly through slots 40.
  • a time winding pawl 42 is provided with an engaging portion adapted to be moved into a position for driving engagement with winding ring 24.
  • the pawl 42 is normally urged toward the teeth of the winding ring by means of a spring 44.
  • the detecting means 47 shown in FIG. 9, does, however, include a portion (as will be more fully explained) for engaging the winding pawl to normally hold this pawl out of position.
  • a spring 46 serves to urge the detecting means toward the right side of FIG. 3 whereby the protuberances 48 shown in FIG. 9 can be moved toward openings in washers or sense reduced thickness of slugs which might be inserted.
  • An operating element 50 shown in FIG. 9 is pivotally mounted on pin 52 which is supported between posts 54.
  • the pin 52 also supports pawl 42 and a second pawl 56 which engages the ratchet wheel.
  • the element 50 de fines engaging surfaces 58, 60 and 62 which are aligned, respectively, with the set screws 32, 34 and 36 as best shown in FIG. 8.
  • the checks are suspended in the upper position shown by the pins 38 and the set screws.
  • the checks are moved out of contact with the set screws and the checks then drop downwardly into contact with the engaging surfaces of element 50.
  • the spans between the pins 38 and the surfaces 58, 60 and 62 correspond with the spans between the pins and the set screws. Accordingly, the checks are moved to a second suspended position.
  • the slug will drop downwardly past the check carrier.
  • the slug must then pass through a second gap between a pin and an engaging surface of the element 50 so that there are two determinations of proper diameter made with respect to each check or slug inserted.
  • the detecting means of FIG. 9 will prevent operation of the time winding mechanisms in the manner described in the aforementioned Sollenberger, et al. patent.
  • a mechanism is employed for holding the protuberances 48 out of contact with checks and slugs in the initial deposit stage.
  • the detecting means 47 of FIG. 9 is provided with an extension 66 which carries a bearing member 68.
  • This member may be a roller or other element adapted to move in engagement with the bearing surface defined by plate 70.
  • This plate is attached by means of fasteners 72 to the housing wall 10 in the embodiment shown; however, the plate could be formed integrally if desired.
  • the extension 66 has a length such that the element 47 is forced inwardly in opposition to spring 46 whenever the check carrier is in the check receiving position shown in FIGS. 2 and 3.
  • the curvature of the plate 70 is such that the element 47 will continue to be pressed inwardly during the initial movement of the check car rier so that the protuberances 48 will continue to be held out of position with respect to the coin slots when the checks drop to the lower position of FIG, 8. Accordingly, these protuberances will not interfere with this dropping movement or with any Continued movement in the case of a rejected slug.
  • the carrier bearing element 68 is moved away from the plate 70 in which case the spring 46 drives the element and the associated protuberances inwardly relative to the check carrier.
  • the element will move inwardly to the extent that the edge 73 will block the movement of a detent on pawl 42 (as explained in the Sollen berger, et al. patent) whereby the driving edge of the pawl 42 cannot be brought into engagement with the winding ring 24.
  • the combination of the inven tion provides the operating features which are characteristic of the aforementioned Sollenberger, et al. patent with modifications accommodating that arrangement to the detection of slugs of reduced diameter.
  • a coin chute 73 (FIG. 3) is provided for collecting any check dropped from the coin carrier and a passage 75 will direct these checks into a coin box located in the meter housing.
  • the illustrated structure provides a second plate 77 which provides a second bearing surface for engagement with the bearing member 68.
  • this bearing member engages the plate 77 as shown in FIG. 3, the protuberances are again backed out of the coin slots in the carrier 22 to insure release of any check in the carrier.
  • FIGS. 10, II and 12 provide an arrangement wherein the check carrier of the invention and winding ring are adapted for the purchase of free time in addition to the time which can be purchased upon the insertion of a proper coin or token.
  • the presence of a proper coin or token in the check carrier will result in the driving of pawl 42 into position for achieving movement of the winding ring:
  • the segments 30 shown in FIG. 10 determine the position of engagement of the winding ring by different coins. For example, where a quarter is inserted, the winding pawl will engage the winding ring in response to the engagement of a quarter with the inner segment 30.
  • the shorter intermediate segment 30 may be engaged by a dime, and the shortest outer segment by a nickel. The size of the segments thus determines the degree of wind and, therefore, determines the amount of time purchased.
  • FIGS. I0, 11 and 12 The arrangement of FIGS. I0, 11 and 12 comprises a drive element 74 which defines an opening 76 at one end for loose fitting around the shaft 78 which has the winding ring 24 attached thereto.
  • a bent-up section 80 of the element 74 is rotated in the path of movement of a post 82 carried by the check carrier 22.
  • a tab 84 is formed in the winding ring 24 for engagement by the edge 86 of the element 74.
  • the check carrier 22 can be rotated until the post 82 engages the section 80 of element 74. This will in turn bring the edge 86 into driving engagement with tab 84 whereby the ring 24 can be re tated until the carrier 22 reaches the limit of rotation.
  • This limit may be controlled by any suitable element blocking continued rotation and is conveniently provided by a formation on an intermediate wall.
  • the position of the tab 84 and the size of element 74 will also control the amount of free time available for purchase.
  • the free time may be limited to a short period, for example 10 minutes, so that it will be usable only by those persons intending to purchase a single item or the like whereby parking spaces will be continuously available for patrons of commercial establishments in the area. For any longer periods of use. the time must be paid for by inserting checks in which case the meter will operate in the conventional fashion.
