Abstract
A coin testing apparatus having a cradle pivotally mounted on a frame about a pivot axis, the cradle including an arm at one side of the pivot axis. A shoulder is fixed to the frame and is spaced from the cradle arm for carrying a true value coin on and between the cradle arm and shoulder when the cradle arm is in an initial position. The shoulder is spaced from the cradle arm for passing the true value coin between the cradle arm and shoulder and to the coin passageway when the cradle is moved to a delivery position. A counterweight is adjustably mounted on the cradle at the other side of the pivot axis for varying the location of the counterweight selectively from the pivot axis to counterbalance the weight of the true value coin so that the true value coin will be moved by the cradle from the initial position to the delivery position at a predetermined momentum, but a coin of different weight carried on and between the cardle arm and shoulder will be moved at a different momentum. With the adjustable counterweight, the coin weight can be detected. The counterweight can be selectively adjusted so that a coin of lesser weight than the true value coin will not move the cradle to the delivery position and will be lodged between the cradle arm and shoulder. The counterweight includes a reduced portion that is located in a channel formed in the cradle and extending radially outward from the pivot axis, and includes an enlarged head portion located outwardly of the cradle channel for digital access for selectively moving the counterweight in the channel.
