Abstract
A multi-cartridge powered dispenser includes a frame having base and top cartridge supports, wheels and a handle. A piston/cylinder is mounted on the frame and at least three cartridges are clamped between the support plates. Each cartridge has a shuttle at the lower end and a discharge opening at the upper end. The piston/cylinder assembly has push rods extending through the base support to move the shuttles in the cartridges. A pressurized fluid supply conduit is connected to the piston/cylinder, and a valve in the fluid supply conduit controls the flow. Discharge cannulae communicate with the outlets the cartridges. Discharge conduits extend between the cannulae and a handpiece for applying the contents of the cartridges to a work surface. The application handpiece can be a sprayer, a roller applicator, or a pour/extrude applicator.
