High Quality Content by WIKIPEDIA articles! In bowling, a pinsetter, or pinspotter, was originally a person who manually reset bowling pins to their correct position, cleared fallen pins, and returned bowling balls to players. Probably due to the nature of the work (low-paid, often part-time, manual labor that most frequently took place evenings), many pinsetters were teenaged boys, and thus pinboy is another name used to describe the job. In 1936 Gottfried Schmidt invented the mechanical pinsetter while with the AMF firm, which largely did away with pinsetting as a manual profession, although a small number of bowling alleys still use human pinsetters. While humans usually no longer set the pins, a pinchaser, or in slang `pin monkey`, often is stationed near the equipment to ensure that it is clean and working properly, and to clear minor jams.
