ABSTRACT:
The apparatus of this invention is designed to dispense material from a container. The container is placed on a base of the apparatus between a pair of hydraulically or pneumatically operated telescoping rods that are secured to the base. A cross bar which bridges the rods is secured to the top end of each rod. This cross bar carries two pump motors and a pair of spaced apart rods. The pair of spaced apart rods are each secured to the cross bar at one end and to a follower plate at the other end. The follower plate is surrounded by wipers and if the material that is to be dispensed must be heated before it can be dispensed, either one of two embodiments of an integrally fabricated combination heater-follower plate with wipers is utilized in place of the follower plate. In addition, optional heat radiating fins may be secured to the bottom of either of the two integrally fabricated combination heater-follower plates, if desired. The apparatus also includes a pump coupler, two pumps, a de-areator system and a reservoir surrounding the de-areator. One of the two pumps is used to pump the material out of the container, through the de-areator and into the reservoir, and the other pump is used to pump the material out of the reservoir. The two pumps are each provided with a slip clutch arrangement to provide a regulated flow of the material being dispensed. The telescoping rods are used to lower the follower plate or the integrally fabricated combination heater-follower plate into the container and permit the follower plate or integrally fabricated combination heater-follower plate to move down inside the container as the material is dispensed from the container.
