  • Patent number: 5056444
    Abstract: A chenille type embroidery machine (10) has an apparatus for rotational steering and height adjustment of a needle (22). An actuator (24) locks or unlocks a locking clip (92) to allow the needle (22) to rotate with a needle height adjuster assembly (46) or to be moved vertically up or down. The needle assembly (46) comprises the needle (22), a needle bar 23, a bar clamp (70), a height adjuster locking block (84), an internal needle height adjuster (88), the locking clip (92) and springs (108a-d). When the actuator (24) is in its "unactuated" condition, the height adjuster locking block (84) is locked to the internal needle height adjuster (88) by the locking clip (92) for rotation therewith. In the unactuated condition, the needle (22) is rotationally steered with the assembly (46). In the "actuated" condition, the actuator (24) extends a shaft (126) to move the locking clip ( 92) and disengage the locking block (84) from the internal adjuster (88).
