Abstract

626,993. Indicating liquid levels. ZACHER, G. Feb. 18, 1947, No. 4729. [Class 123(i)] Apparatus for indicating a predetermined minimum level of oil &c. in a reservoir 1 comprises a float-actuated rod 8 which projects through the reservoir closure 2 and is fitted externally of the reservoir with an adjustable conductor disc 10 adapted, in its lowermost position, to bridge a pair of contacts 3, 4 in circuit with a signal lamp 11. The said contacts 3, 4 are mounted on an insulating base 5 on the closure 2 with the contact 3 earthed by a wire 6, leading to a hollow guiding bolt 7 for the rod 8, and the contact 4 connected to the lamp 11.
