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.

Abstract: A tufting machine employs a manual crank and gearing on one side of a support plate for driving a rotary eccentric and a crank arm on the other side. The rotary eccentric causes orbital motion of the upper end of a body, and a hollow needle fixed to the body is guided in a stationary ring fixed to the support plate. The crank arm is connected by a link to a slide block guided for movement longitudinally of the body. A solid needle fixed to the slide block has a lower end which moves above and below the yarn entrance window near the lower end of the hollow needle. A grip handle at the upper end of the support plate enables the device to be manually tilted to control the length of the stitch.
