Abstract A portable hand-carried battery-operated electronic automobile counting device designed for counting automobiles entering a paid parking area as a check on attendant's collection of parking fees. The devices will normally be stored when not in use in the manager's office and will be given to individual attendants for placement at appropriate parking entrance driveways prior to the start of the event which will attract persons arriving by automobile to the parking area. The device is equipped with a counter and a locking energizing switch. On delivery of the device to the attendant, the supervisor will reset the counter and lock the energizing switch in "on" position. The device is equipped with a second series connected position responsive switch which maintains the device in deactivated position while being manually carried to its position of use, and which automatically completes the energizing circuit when placed in its position of use.
An automobile counting device comprising: a portable, manually carried, thin flat housing having a car-counting position of use laid flat-wise on a driveway traversed by automobiles to be counted with the major dimension of said housing substantially parallel to the ground, and a second, upended, non-counting, carrying position with said major dimension substantially perpendicular to the ground, said housing being dimensioned to lie in counting position within the span of the wheel track and within the ground clearance of automobiles to be counted; electric means carried by said housing for sensing the passage of an automobile thereover and including an electromagnetic radiating loop carried by said housing adjacent the periphery of said major dimension for disposing said loop in a plane substantially parallel to the ground in said position of use; a counter connected to said means for accumulating and displaying the number of automobiles passing over said housing in its position of use; means functioning when said housing is in its upended carrying position to prevent operation of said counter; and supervisor-controlled locking means controlling the energizing of said circuit and the reading of said counter.
