Abstract: A plurality of presettable digit wheels are rotatably mounted on a first axis. Each of said wheels is rotatable to a plurality of preset positions corresponding to respective values of an associated digit position of a preselected count. Retaining means retain said presettable wheels in said preset positions during a counting operation of the counter. A signal generator comprises axially movable cam follower means arranged to generate a signal when said counter has counted to said preselected count. A plurality of presetting members are associated with respective ones of said presettable wheels and pivoted to a stationary first pivot. At portions remote from said first pivot, said presetting members are engaged by a guide member, which is pivotally movable between first and second positions to move said presetting members about said pivot out of and into engagement with said presettable wheels. First spring means are adapted to urge said guide member to said first position.

Abstract: At least one presetting digit wheel consists of a rotatably mounted digit-carrying wheel part, a rotatably mounted resetting wheel part, and a non-positive two-way coupling means connecting the digit-carrying wheel part and the resetting wheel part for joint rotation. A rotatably mounted resetting shaft is provided. Lost-motion one-way coupling means are adapted to connect the rotatably mounted resetting shaft and the resetting wheel part for joint rotation only in one sense and only when the resetting shaft and said resetting wheel part are in a predetermined rotational position relative to each other. Detent means are adapted to hold the resetting shaft against rotation in a predetermined rotational position thereof, and locking key means are manually operable to hold the digit-carrying wheel against rotation when the resetting wheel part is rotated by said resetting shaft.

Abstract: A plurality of counters are removably held by counter holder means at predetermined locations. Each counter is adapted to perform incremental and decremental counting operations. A program timer is operable to produce first and second control signals in alternation in accordance with a predetermined time schedule. Drive means are carried by said counter holder means and comprise drive output means and are operable under control of said program timer to rotate said drive output means in a decremental sense when said control timer produces said first control signal and in an incremental sense when said control timer produces said second control signal. A plurality of clutch means are carried by said counter holder means and connected to said drive output means and associated each with one of said counters. Each of said clutch means is adapted to assume a first state for driving the associated counter in an incremental sense and a second state for driving the associated counter in a decremental sense.

Abstract: The counter means serve for a counting of events. A counter is provided as well as a code detector adapted to receive a coded punched card in a predetermined position. Counter control means are operable to control said counter in response to the arrival of said card in said predetermined position. Said code detector comprises replaceable, pivoted code detector elements, which represent a predetermined code and are adapted to enter holes in said punched card if, and only if, said holes also represent said predetermined code. Said code detector prevents a movement of said card to said predetermined position unless said code detector elements have entered said holes in said card.
