Abstract
A machine for performing needlepoint or the like wherein successive loops of a single strand of yarn or the like are inserted through fabric, the machine including a carriage mounted for slidable movement in a given direction, the carriage having an indexable open framework roller mounted thereon, the roller being adapted to support a fabric for receiving the yarn. First and second members are pivotally mounted about a common axis within the machine, each of the members having arm portions extending toward the roller and adapted for insertion through the fabric carried thereby. The arm of the first member is configured in the shape of a needle having an eye adapted to receive the yarn therethrough, the needle arm being channel-shaped in cross section for selectively receiving the arm of the other member in abutting sliding relation, the free end of the arm of the second member being notched. A double-faced cam disc is interposed between the first and second members, the disc being rotatable by a hand crank and having guideways formed in opposing surfaces for matingly coacting with cam follower projections on each of the first and second members. The cam guideways are configured so that upon rotation of the crank the needle with the yarn is inserted through the fabric, the notched portion of the other arm slidably engages the needle arm while so positioned to retain the loop within the fabric, the needle arm is withdrawn from the fabric, the other arm is moved laterally while engaging the fabric to increment the roller, the needle arm then inserts another loop of yarn, and the notched arm is then withdrawn to thereby continuously loop a single strand of yarn within the fabric.
