ABSTRACT:
Sewing apparatus utilizes a conventional multi-head sewing machine for embroidering or stitching and includes a single rail pantograph with a double ended electric motor and ribbed drive end and support arm. A multi-purpose holding bracket allows the operator to quickly change from embroidering tubular goods such as sweatshirts to baseball caps or other circular type goods without tools by the use of an easily releasable hoop support boom. An embroidery hoop assembly provides ears which can be easily and securely positioned on the hoop support boom for secure holding thereto during high speed embroidering operations. The ribs on the drive end of the pantograph prevent warping of the end during the high speed operations.
