Abstract: A wall compound applicator appliance that has a work station including a reservoir for containing a supply of wall compound, an air compressor, an applicator tool, a portable compressed air tank to operate the applicator tool, and a carrying strap assembly to attach the tank to a user with the tank connected to the applicator tool. The applicator tool has a cylindrical, tubular body to receive a supply of wall compound. The reservoir has a transport tube that is connectable to a one-way fill valve on the applicator tool to refill the applicator tool with wall compound. An adapter is connected to the work station and has a fitting to connect to a refill airline that is connected to the portable compressed air tank in order to refill the tank at the same time that the applicator tool is being refilled. Once the applicator tool and the compressed air tank are refilled, the workman is free to move about the work area independent of a work station and the air compressor.

Abstract: A tool for the application of joint compound to a corner joint formed at the intersection of two drywall panels during new construction, preparatory to finishing the corner. The corner can have an obtuse angle. The tool has a generally flat top surface with leading edges that converge toward an apex. A housing on the top surface is in spaced relationship from the leading edges and includes a chamber for receipt of joint compound from a pressurized source. The housing has discharge ports that are forwardly directed. In use the head is positioned in the corner and tilted in the direction so that the discharge ports face the corner. The head is tilted to an extent as may be necessary to cause the leading edges to engage the adjacent walls forming the corner. In this position, the head is drawn along the corner as the joint compound is discharged into the corner vicinity and is troweled by the leading edges.
