ABSTRACT:
A hand held motor driven tufting machine employs concentric needles which reciprocate and oscillate in timed relationship to form loops of yarn on a backing sheet. An electric motor drives the moving parts of the device, and this motor has a metallic frame anchored within and closed by a lightweight housing formed of plastic materials. An improved form of joints connect the metallic frame of the motor to mounting supports formed of plastic materials to prevent failure of the joints under stresses caused by gravity and by vibrations generated by a reciprocating motion of the moving parts.
