Title: Apparatus for counting and sorting coins
IPC: G07D3/04
Filed: 1959-04-20
Abstract: 919,533. Sorting coins. ALMQUIST, G. F. W. April 20, 1959 [April 21, 1958], No. 13358/59. Class 27. [Also in Groups XVII and XIX] Apparatus for counting, storing, indicating the value of and wrapping coins may function in three distinct ways : (1) to sort and indicate the value of a mixture of coins, and, when coins of one value only are supplied; (2) to count the number of such coins ; or (3) to count a predetermined number of such coins. As described, for sorting a mixture of coins, the coins are fed from a rotary conveyer 10 driven by an electric motor (not shown) and roll down a track 11 until they touch one of a number of contact arms A1-A8 spaced at decreasing heights above the track 11. When a coin touches one of the contact arms A1-A8, a magnet UM, Fig. 6, is energized to move via a spring-loaded pawl 20 a pin U2 into the track 11 thereby ejecting the coin. When the pawl 20 disengages a groove in the pin U2, the pin is returned to its original position even though the magnet U2 remains energized. In a modification (Figs. 4, 5, 7, not shown), the coins, instead of actuating contact arms A1-A8, are selectively displaced from the track 11 by wedges and drop on to channels where they remain on edge, one on top of the other, for counting, thereby freeing the track 11 for the passage of further coins.
