ABSTRACT:
In a shuttle embroidering machine a plurality of needle carriers and drill carriers are arranged to be displaced at approximately right angles relative to the plane of an embroidery frame. Each needle carrier has a needle inserted into one end and each drill carrier has a drill inserted into one end. A generally horizontally extending arm is attached to the opposite end of each needle carrier and drill carrier. The arms are pivotally displaceable about a horizontal axis. One end of each arm is connected to a needle carrier or a drill carrier and the other end is displaceable along a path due to the pivotal displaceability of the arms about horizontal axes. A drive element provides the operative displacement of the needle carriers and drill carriers. The arms are shaped for selective form-locking engagement with the drive element. Individually controllable locking members are located in the path of displacement of the ends of the arms spaced from the needle carriers and drill carriers so that the needle carriers and drill carriers can be held in an inoperative position. Control members are engageable with the arms for selectively pivoting the arms into or out of locking engagement with the locking arms.
