Abstract
An indicator gauge may utilize a motion amplifying gauge movement. The motion amplifying mechanism makes it possible for a diaphragm-type pressure gauge to provide large angular displacements for an indicating pointer. The indicator gauge may be configured to have a maximum readout visibility in the range from about 0.degree. to about 270.degree.. A single-piece crankshaft located on an adjustable mounting translates the short range of motion of a diaphragm button to a pivotal gear segment. The crankshaft may be configured as a C-shaped crankshaft or an L-shaped crankshaft. The pivotal gear segment may be wedge-shaped or have an extension arm for contact with the crankshaft. The crankshaft may also contact a downwardly or upwardly extending boss located on the pivotal gear segment.
