Oil filler for the Johnson & Phillips oil insulator

JOHNSON AND PHILLIPS’S FLUID INSULATOR.

WE give an illustration (half real size) of an ingenious little apparatus designed for the purpose of filling with insulating fluid the chamber in the well-known fluid insulator, patented by Messrs. Johnson and Phillips. A, is a cup made of a size to hold exactly the right quantity of the fluid to fill the insulator chamber. B, a tube bent into a shape so that the point, C, when placed in position, overhangs the fluid chamber, and D a handle which when turned by the finger opens a tap, and allows the fluid to run from the cup, A, into the chamber of the insulator; this handle is fitted with a spring, which closes the tap automatically when the finger is removed.

This apparatus, which we have no doubt will be appreciated by those who use the fluid insulator, was designed by Mr. Wittkugel, of Kurachi, the ingenious mechanician to the Indo-European Government Telegraph Department.
