Abstract: The present invention relates to an apparatus for injecting viscous materials. The apparatus includes a vertically adjustable manifold valve which receives a continuously circulating supply of pressurized viscous material. The manifold valve is positioned above a container or mold cavity to be filled with the viscous material. When the manifold valve is opened, the viscous material is injected into the containers or molds.

Abstract: A transfer mechanism for dumping the contents of a shipping drum into an open-topped mixing vessel has a rotatable frame spaced above the support surface on which the vessel and drum can be rolled about, the frame having an annular plate and hooks on one side of the plate for lifting and holding the vessel against that side of the plate and a fork on the opposite side of the plate for lifting and holding a drum against that opposite side of the plate. By first picking up the vessel, rotating the frame 180.degree. to turn the vessel upside down, picking up the drum, and rotating the frame to its original position with the drum upside down, the drum contents are transferred to the vessel through the annular plate in a confined manner. A suction chamber is mounted on the transfer mechanism to withdraw any remaining loose material or dust from the shipping drum before it is removed from the transfer mechanism.
