发明名称 Machine embroidery hoop
摘要 A pair of embroidery hoops especially adapted to be used with a sewing machine including an inner hoop of fixed diameter and an outer hoop composed of substantially quadrantly related, arcuate hoop segments adjustably interconnected by circumferentially acting screw type connectors, permitting one-handed adjustment of the outer hoop without distortion of the work material. Each of the two hoops is notched along its upper edge to facilitate movement of the hoops under and out from under the presser foot and needle of the sewing machine. Opposed lug members extend inwardly of the inner hoop and provide surfaces to be contacted by the user's thumbs or forefingers for ease of manipulation of the hoops while doing embroidery.
