ABSTRACT:
A welding wire dispenser for dispensing wire to a wire feeder comprising a floor-engaging support which has an annular brake bad 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 horizontally disposed accumulator pulley is freely rotatably mounted on the upper end of the shaft above the wire coil. A brake arm is secured to the upper end of the shaft and extends therefrom for rotation therewith. A second pulley is supported on the outer end of the brake arm and has the wire extending from the wire coil received thereon. The wire, after extending around the second pulley, is wrapped around the accumulator pulley for two to three turns and then extends to the wire feeder.
