ABSTRACT:
An apparatus for high speed application of locking compound to threaded fasteners. A chute guides a continuous flow of fasteners from a feeder bowl to a transporting wheel supported for rotation about a vertical axis. The wheel is provided with a magnet around its periphery which magnetically engages the heads of the fasteners to hold their threaded shanks extending horizontally outwardly from the periphery of the wheel. The fasteners are heated by induction heating and a liquid compound is applied under pressure to a controlled portion of the threads through a continuously vibrated nozzle. Heated air is then applied to drive off solvent from the compound. An air blower then applies ambient temperature air, followed by injecting a cooling air mist containing soluble oil which prevents the fasteners from adhering to each other prior to the hardening of the compound. A pick-off wheel magnetically driven by the transporting wheel separates the fasteners from the transporting wheel.
