Abstract: Apparatus utilized in combination with a carriage reciprocating between a primary base position and a second position spaced away from the primary base position. The apparatus varies the distance of the second position of the carriage from the primary base portion of the carriage and includes a stop surface on the carriage and a plurality of secondary stop surfaces operatively associated with the carriage stop surface. The secondary stop surfaces are each movable between at least two operative positions, a first operative position in which one of the secondary stop surfaces contacts the carriage stop surface when the carriage is moving away from its primary base position, and, a second operative position in which another of the secondary stop surfaces contacts the carriage stop surface when the carriage is moving from its primary base position. When a secondary stop surface contacts the carriage stop surface, the carriage is halted in its second position.
