Abstract: A stand for supporting a hopper for applying joint compound to a drywall corner bead has first and second pairs of legs which cross over and are pivoted together at their crossover point in a scissors-like manner. Each pair of legs has a cross bar extending between its upper ends, and spaced connecting straps extend transversely between the cross bars in the deployed position of the stand, the connecting straps being of predetermined length to control the maximum spacing between the cross bars. Each connecting strap is slidably engaged with the respective cross bars for movement along the cross bars. A hopper is seated on top of the cross bars with a reduced length lower portion of the base extending downwardly between the cross bars. The two connecting straps are moved into engagement with opposite sides of the hopper base in order to support the hopper.

Abstract: A hopper apparatus for applying joint compound to corner beads has a hopper for holding a quantity of joint compound and a feeder apparatus secured across the lower end of the hopper. The feeder apparatus has a channel and a series of elongate feeder inserts for selectively securing in the channel. A first set of outside feeder inserts each have a generally V-shaped indented groove extending along their length for guiding an outside corner bead through the feeder apparatus, while a second set of inside feeder inserts each have a generally V-shaped ridge extending along their length for guiding an inside corner bead through the feeder. The feeder inserts in each set have grooves and ridges of different angles and corner shapes matching those of a plurality of different inside and outside corner beads, and are releasably secured in the channel.
