Abstract : It is therefore the principle object of the present invention to provide apparatus for accurately metering the proper proportion of very viscous components, feeding the materials to a mixing device, and dispensing the mixed compound for use. This object is accomplished in the present invention through the use of hydraulically driven shovel pumps which force a measured volume of each component to the mixing device. The chamber in which each component is disposed is continuously adjusted in volume so that the component completely fills the chamber and the component experiences a constant compressive force to ensure that each operation of the pump meters the desired volume of the very viscous components.
