Abstract
A welding wire dispenser for dispensing wire to a wire feeder comprising a floor-engaging support which has an annular brake pad positioned on the upper end thereof. A ball screw assembly is mounted on the support and has a coil spring secured thereto which yieldably resists the rotation of the ball screw in one direction. A shaft is secured to the upper end of the ball screw assembly and is vertically movable therewith. A coil support is rotatably mounted on the shaft above the support and is vertically movable with the shaft. The coil support is adapted to support a coil or reel of welding wire thereon. The coil support has a horizontally disposed annular portion at its lower end which is adapted to frictionally engage the annular brake pad to limit the rotation of the coil support at times. A multiple arm assembly is secured to the upper end of the shaft and extends therefrom. A pulley is supported on the outer end of each of the arms on the arm assembly and have the wire extending from the wire coil received thereon. As the wire feeder pulls wire from the coil, the arm assembly rotates which causes the shaft and the ball screw assembly to rotate and to raise the coil support upwardly so that the coil support will freely rotate. A spring is engagement with the ball screw assembly for rotatably urging the shaft in a direction so that the ball screw assembly will move the shaft downwardly relative to the support.
