  • Patent number: 10293350
    Abstract: An improved spray apparatus designed to optimize the pattern of the texture material and the performance of the spray apparatus to look and perform similar to a hopper texture gun or texture spray rig used by professionals. The spray apparatus, has a housing defining a cavity. A transfer wheel is rotatably mounted to the housing, the transfer wheel having a hub defining a hub axis, and a plurality of transfer flaps. A propeller is rotatably mounted to the housing and positioned above the transfer wheel, the propeller having a spindle and a plurality of fins. A firing pin is attached to the housing above the propeller. An actuator is mounted to the housing to cause the propeller to rotate. A gate may be provided to control the flow of the material to the transfer wheel.

  • Publication number: 20070145207
    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.
