Abstract
A combined dispensing head and gauge for indicating the quantity of material in a container is disclosed. The combined dispensing head and gauge is comprised of a one-piece dispensing head which includes a dispensing head conduit, fiducial marks adjacent to the dispensing head conduit for indicating the quantity of material present in the container, a sealing flange for sealing the dispensing head with respect to the container, and a chamber for receiving a movable indicator. The combined dispensing head and gauge is further comprised of a level responsive device such as a float responsive to the level of material in the container, and a movable indicator pointer received by the chamber adjacent to the fiducial marks for indicating the quantity of material present in the container. The indicator pointer is controlled by the float and is pivotally supported thereon. A material supply conduit is connected to the dispensing head conduit for conveying material in the container to the dispensing head conduit. The material supply conduit also supports the float by a pivotal connection with the float.
