ABSTRACT:
An upholstery machine for the tufting of buttons within cushions wherein a needle picks up a string loop which is attached to a lower button and is then caused to penetrate the cushion. The needle is withdrawn and the string loop secured to an upper button. A button feeding mechanism is utilized which comprises an enlarged, elongated coil spring. The coil spring supports a single lower button with its attached loop of string at each coil of the spring thereby forming a row of the button assemblies. The inner end of the coil spring is attached to a power source which is to incrementally rotate the coil spring to discharge a single button assembly from the free outer end of the coil spring at a selected instant. The discharged button assembly is to be engaged with the needle. The power source includes appropriate gearing mechanism to reverse rotation of the coil spring to facilitate the loading of the coil spring with the button assemblies.
