To reset, automatically, all the bowling pins for one game of bowling, or only those which have not been knocked over by a bowled ball, a frame is provided which is supplied with tipping baskets, each one adapted to hold a bowling pin and having electromagnetically operated flaps engaging over the neck of the bowling pin. The frame, with the baskets upright and the flaps open can be lowered to pick up the pins which have been left standing, the frame raised, and empty baskets are, selectively, filled with pins; the frame is then again lowered, and the flaps opened to release all the pins which were in baskets. |
