ABSTRACT:
A work element, such as a wire stitching head, is provided which is adapted to be manually advanced and positioned along a support rail. The work element is carried by a carriage adapted to be movably mounted on a support rail, said carriage including bearing means, such as roller means, operably connected thereto and adjustable between engaging and retracted positions and adapted to contact the support rail and facilitate movement of the carriage along the support rail when the bearing means is in its engaging position. Each carriage also includes selectively positionable securing means, such as clamping members, for preventing the advance of the carriage along the support rail when the bearing means is in its retracted position, which means are adjustably connected to the carriage and adapted to engage the support rail.
