Definitions

  • ABSTRACT OF THE DISCLOSURE A parking meter preventing the fraudulent use of false coins such as iron washers, the thickness of which is less than that of the coins required for operation of the latter; to this end, the lever normally controlled by the coin upon abutment against a stop at the end of its travel so as to operate the mechanism of the meter, is provided in registry with the coin-receiving slot with a notch the breadth of which is smaller than the thickness of the required coins; thus, the notch does not prevent normal operation of the lever by said required coin, but is engaged by the thinner false coin the shifting of which by the stop cannot therefore act on the lever.
  • My invention relates to those types of semiautomatic parking meters wherein the coin introduced into the slot of a member rotating in unison with the control handle slides through its edge along an arcuate slideway provided at a suitable point of its outline with an extra-thickness urging the coin against a catch-carrying lever whereby said coin causes said lever to pivot and to make its catch engage a ratchet wheel so that the latter progresses by one step together with the arrow showing the authorized duration of parking while the arrow-driving clockwork is simultaneosuly started in a manner such that the end of the reverse movement imparted to the arrow allows the coin to drop into the collecting chamber of the meter.
  • the arrangement of the parts is such, both as concerns the breadth of the slot in the rotary member and the length by which the coin is to travel before it engages the ratchet wheel, that only round coins the diameter of which is accurately equal to that of the coin required may operate the meter.
  • metal or the like washers are sold in trade the diameter of said washers being equal to that of such coins and therefore may be successfully used in order to defraud the meter.
  • My invention which has for its object to prevent such a fraud and to cut out its effects, covers to this end a very simple arrangement through which such washers, always thinner than the coin required, cannot produce operation of the meter; the latter not being locked by the washer, its control handle may execute its normal angular travel and allow the washer to drop into the collecting chamber of the meter after which said handle returns into its inoperative position without moving the arrow indicating the parking time and without releasing the clockwork.
  • the catch-carrying lever at a point adapted to register with the edge of the coin guided by the slot, a notch the breadth of which is slightly less than the breadth of said edge so that the coin abuts against the lever which it is caused to engage operatively, said abutment being obtained no longer throughout the breadth of said edge as in the present parking meters, but only through the fraction of said edge facing the projecting ridge defining the notch in the lever.
  • a washer thinner than the coin when urged against the extra thickness of the slideway guiding it, engages freely the notch in the lever without acting on said lever 3,701,600 Patented Oct. 31, 1972 and consequently the catch remains spaced during its angular movement with reference to the intervals between the ratchet teeth, the ratchet remaining thus unaffected by the false coin or washer.
  • FIG. 1 is a cross-section passing through the axis of the control handle.
  • FIG. 2 is a partly sectional view of the rotary member with the catch-carrying lever in its inoperative position.
  • FIG. 3 illustrates the lever when seen at right angles with reference to FIG. 2.
  • FIG. 4 is a front view of a disc-shaped part the edge of which is indented to form a ratchet wheel.
  • FIGS. 5 and 6 are both cross-sections passing through the rotary axis of the control handle and show respectively the operative action of a coin and the inoperative action of a false coin or washer.
  • FIG. 7 illustrates on a larger scale the notch formed in the lever, a coin being drawn in solid lines to show the operative abutment of the coin against the edge of the notch while the washer drawn in dot-and-dash lines enters the notch and cannot operate the meter.
  • FIG. 8 shows on a larger scale than that of FIG. 6 how the meter may be fraudulently operated by a washer showing a large clearance with reference to the slot in the rotary member.
  • FIG. 9 shows on a larger scale an arrangement provided with a magnet cutting out prefectly such a possibility of a fraudulent operation.
  • FIG. 10 is an exploded perspective assembly of the clock movement and indicator assembly of a parking meter according to the present invention.
  • FIG. 1, 1 designates the control handle rotating round the axis of its spindle 0 while 2 designates the section of the casing carrying said spindle, 3 the rotary part keyed to the spindle and carrying the slotted member 4.
  • Said member includes a support 5 to which is pivotally secured at 6 a lever L. The latter is held in its inoperative position by a spring 7 and is provided with an extension La adapted to slide in an auxiliary slot crossing at right angles the coin-receiving slots of which only the slot 8 adapted to receive coins of a predetermined denomination is to be considered in the present disclosure.
  • the catch is constituted by a lever arm 9 (FIGS.
  • FIG. 5 shows how the coin M operates: when the latter carried along by the slotted member 4 reaches the extra thickness S in its arcuate slideway 14, it is urged inwardly in the direction of the arrow F1.
  • the extension La of the lever L to be actuated by the coin is notched according to my invention as illustrated more clearly in FIG. 7.
  • a notch E the breadth of which is slightly less than the thickness of the coin M so as not to interfere with the operation of the latter.
  • the coin engaging the notch E along the side which projects further than the other side so as to form a shoulder abuts against the shoulder 16 terminating the last-mentioned other side.
  • a washer R may enter freely (FIGS. 6 and 7) the notch E the breadth of which is larger than the thickness of the washer so that said washer cannot act on the extension La of the lever L which remains inoperative (FIG. 2) and does not act on the ratchet wheel D during rotation of the handle 1.
  • FIG. 7 It has been assumed in FIG. 7 that the washer R engages with a nice lit the notch E with one surface facing the longer side 21 of the notch, said washer being almost as thick as the required coin M. However, this may not be the case and the washer may be somewhat thinner as illustrated in FIG. 9, said washer asuming then an oblique position and abutting against the ridge 16 of the notch E facing the slot 8, whereby the washer is held in a position such that it operatively engages the lever extension.
  • FIG. 9 illustrates an arrangement cutting out such an undesired operation.
  • a parking meter comprising a rotary hand-operable member adapted to execute a predetermined angular travel and provided with at least one coin-receiving slot,
  • a stationary guide engaging the edge of the coin projecting rearwardly out of the slot during said travel of the rotary member, said guide including a projection adapted to make the coin recede in the slot at the end of said travel, and a time indicator and a clockwork returning the time indicator to zero during the elapsing of the allowed parking period;
  • the improvement comprising a catch acting on the time indicator to shift the time indicator to its predetermined operative position and to release the clockwork and a lever pivotally carried by the rotary member and pivotally carrying the catch, said lever being provided in registry with the slot with a notch the breadth of which is slightly less than that of the coin required for operation the notch having a shoulder therein on which the coin impinges during receding movement of the coin at the end of said travel thereby to operate the lever and the catch carried by the latter, any false coin thinner than the required coin when substituted for such a required coin entering the notch in the lever without moving the latter.
  • a parking meter as claimed in claim 1 wherein one of the transverse sides of the notch in the lever extends towards the corresponding side of the slot in normally alined relationship thereby to form a shoulder bearing the coin abutting against the outer edge of the opposite shorter side of the notch.
  • a parking meter as claimed in claim 1 wherein one of the transverse sides of the notch in the lever extends towards the corresponding side of the slot in normally alined relationship thereby to form a shoulder bearing the coin abutting against the outer edge of the opposite shorter side of the notch, the meter including furthermore means urging any false coin introduced in the slot into contact with said corresponding side of the slot throughout the extent of said coin.
  • a parking meter as claimed in claim 1 wherein one of the transverse sides of the notch in the lever extends towards the corresponding side of the slot in normally alined relationship thereby to form a shoulder bearing the coin abutting against the outer edge of the opposite shorter side of the notch, the meter including furthermore a permanent magnet embedded in the rotary member and the outer surface of which is flush with said corresponding side of the slot, said magnet urging any false coin introduced in said slot into contact with said corresponding side throughout the extent of said coin.
