Abstract

803,255. Indicating liquid levels. MOSS, H. Feb. 27, 1957 [Feb. 28, 1956], No. 6124/56. Class 123(1) An oil level sight glass fitting b for an oil system comprises a disc c of glass or other transparent material screwed into an aperture in the front of the fitting and a non-return valve a having a pointed stem e which bears on the glass thereby holding the valve off its seating against the closing pressure exerted by a spring d. If the glass is accidentally fractured or is removed for cleaning the spring causes the valve to close to prevent loss of oil from the system.
