Multiple automatic metering device
First Claim
1. A multiple automatic metering device particularly suitable for metering and admixing paints, wherein there are provided a series of units each of which comprises a container and a metering head connected between each other by a communication chamber having therein interception means displaceable into one of two positions and a discharge conduit toward a single central collecting container, in each container and in each metering head there being provided stems operated by a single plate capable of reciprocating movement, acting simultaneously on all units, said stems being connected to mixing blades for the containers and to sealing gaskets for the metering heads, so that for one position of said interception means there is a flow of the product to be dosed from the container to the metering head and vice versa under the action of the plate capable of reciprocating movement and that for the other position of interception the metering means discharge directly through the discharge conduit, there being obstructed the communication toward the container.

5. A metering device for metering liquids comprising:
-
at least one liquid container for holding a supply of liquid; a mixing blade movably mounted in said container, extending across said container and spaced from interior walls of said container; a blade shaft connected to said mixing blade and extending out of said container; a metering head having a metering space communicating with said container; a head shaft slidable in said metering space for changing the volume of said metering space; a common plate connected to said head and blade shafts for simultaneously moving said head shaft in said metering space to draw liquid into and discharge liquid from said metering space, and said blade shaft in said container to move said mixing blade and mix liquid in said container; and valve means connected between said container and said metering head having a first position opening communication between said metering space and said container, and a second position for closing communication between said metering space and said container and opening communication between said metering space and a discharge outlet for discharging liquid from said metering space with movement of said head shaft to decrease the volume of said metering space. - View Dependent Claims (6, 7, 8, 9, 10)
