ABSTRACT:
In a bowling game, an apparatus to automatically retrieve knocked down tenpins from the skittle alley, after each ball strike aimed thereat. The apparatus includes a series of cables each connected to the head of a corresponding one of the tenpins. The cables are connected to a computer controlled slider, guidingly carried by a horizontal rail and power driven in reciprocating motion by an endless belt. Once at least one tenpin is struck by a ball, all tenpins are lifted by their cables through actuation of the motor of the power driven endless belt. The slider then returns to its initial position, which will enable the cables to yield to the weight bias of their pins and therefore allow all of the latter--but for the knocked down tenpin--to fall back to their upstanding position on the skittle alley. The knocked-down pin has been identified by optical sensors connected to the computer, and the computer will have actuated a cam-type cable lock to prevent release of the knocked down pin cable under the weight of this latter pin.
