  • Gauge assembly
    Patent number: 4175444
    Abstract: A gauge assembly is disclosed having a casing formed of two separate cup members joined together in back-to-back relationship so as to form a relatively thick partition wall within the casing. The wall acts to reduce the possibility of parts being projected forward toward an observer in the event the gauge actuating mechanism, which is located behind the partition wall in the casing, should fail.

  • Illuminated indicator gauge
    Patent number: 4004546
    Abstract: An indicator gauge has a flat light conducting prism with an upper beveled surface positioned between the translucent dial and movement of the indicator. The prism receives light from a source located in the rear portion of the gauge and laterally of said movement, such that light is reflected downwardly by the beveled edge through the prism to illuminate the dial and pointer. A second annular prism may also be provided with a beveled surface so as to reflect light from the source across the face of the dial.
