Metering and mixing paint toners and pigments

摘要

The paint toner or pigment is stored in a container (1) which has a spray mouthpiece (2) and contains a piston (3). The piston is operated by a rod (4) engaging in the container and driven by a lever mechanism (5) with lever (6). The lever (6) has a scale (7) for accurately reading off the displaced amount of toner.The scale can be located on a circular curved scale support (8) on which a displaceable detent element is mounted as a stop (9) for the lever. For single handed operation the device can be a gun with the lever forming the handle.
