Abstract
A device for dispensing ingredients, such as the ingredients for a dental amalgam, has a handle portion and a head portion formed of mating parts with the handle angulated to the head and formed for convenient gripping by the user's hand. A slide mounted in the head slides laterally when pushed by the user's thumb to transport measured ingredients to a common aperture for delivery into a container. The container, when put in place, releases a latch that holds the slide normally in measuring position and prevents transport of the ingredients unless the container is in position to catch them. Adjustment of a measuring chamber for liquid mercury, to accurately proportion it, is by a valve having an end projecting, more or less, into a chamber, so as to vary the volume of the chamber. The position of the valve is controlled by a rectilinearly movable cam whose position may be fixed by a lock nut which normally is inaccessible in a recess in the head portion.
