Description
- The invention relates to drywall construction. More specifically, the invention relates to a device for applying drywall mud or joint compound to corner beads or tape-on-trims prior to their attachment to joints or corners between adjacent drywall panels.
- Corner beads are elongate, narrow strips of metal, plastic, or metal with a paper face on one side, or the like, folded or angled along their longitudinal center line, or along a line offset from the center line in some cases, to produce a generally v-shaped cross-section. They are made in various angles and corner shapes, including sharp 90 degree angle corners, sharp corners at other angles, rounded or so-called “bullnose” corners of various angles, and offset or L-shaped corners. Corner beads are also designed for covering both inside (concave) and outside (convex) corners. For application to an inside corner, drywall mud is applied to the outside (convex) faces of an inside corner bead. For application to an outside corner, drywall mud is applied to the inside (concave) faces of an outside corner bead. Joint compound is applied to the appropriate faces of the bead, and the bead is then pressed against the corner, with the joint compound forming an adhesive joint between the bead and corner.
- Although drywall mud or joint compound may be applied to corner beads by hand, this is a time consuming and inconvenient process. Hopper devices have been proposed in the past for applying joint compound to the inside faces of an outside corner bead. One such apparatus is described in U.S. Pat. No. 5,169,449 of Raught. The apparatus comprises a hopper with a V-shaped trough in its base, and triangular shaped end walls at opposite ends of the trough forming a generally V-shaped gap between the lower edge of each end wall and the trough. Removable end panels are adjustably secured to the end panels to adjust the height of the gap. A corner bead is fed through the base of the hopper from one end wall opening to the opposite end wall opening, and drywall mud in the hopper will be applied to the upwardly facing surfaces of the corner bead. All except a thin layer will be scraped off by the edge of the end panel as the corner bead exits the hopper. Removable liners may be placed into the hopper to define different trough cross-sectional shapes, corresponding to different shapes of corner bead, and associated with end panels with corresponding edge shapes.
- Other systems have been designed which allow joint compound to be applied to either the inside or outside faces of the corner for applying the corner bead to inside or outside corners. For example, U.S. Pat. No. 6,907,908 discloses a hopper apparatus for applying joint compound to corner beads that 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.
- One problem with prior art hoppers having corner bead feeders for applying joint compound is that they are used with hoppers that must be filled and then emptied with every use or the drywall compound within the hopper will become too dry to work with. This represents lost time and tedious work to a drywall finishing professional. Moreover, prior art devices for applying drywall compound to a corner bead use panels which scrape the excess drywall compound from the corner bead to obtain the desired surface for coating. However, in the past it has been thought that thin panels were most advantageous, perhaps due to the abrasiveness of drywall compound. However, thin panels allow drywall to escape as the hopper sits, particularly when the hopper is full of compound, and if corner bead is pulled through on an angle, the thin panels will deflect to wipe of excessive amounts of compound.
- The present invention comprises a device for applying drywall compound to a length of corner bead. The device comprises a trough for holding a quantity of drywall compound and an opening at the bottom of the trough through which a length of corner bead may be inserted. A removable block is located near an opening in the trough having a plurality of grooves located therein for preventing excess drywall compound from adhering to the bead while allowing sufficient compound to remain with the bead. A flange attached to the top of the trough is adapted to be attached to a bucket, the bucket having a portion of the bottom removed, to provide drywall compound to the trough.
