Abstract: The invention is an improved safety sight for liquid level detection in containers of liquids. The safety sight provides a means for such detection of the liquid level in automobile radiators, water tanks, oil tanks and other such vessels. The safety sight is composed of an insert for the vessel containing the liquid, a transparent lens or window piece to observe the liquid level, a retainer to hold the lens or window piece in the insert in the vessel and a seal under the lens or window piece to prevent leaks.

Abstract: This invention relates to an indicating device that permits a sight reading of the level of liquid contained in or flowing through a flexible liquid carrier, such as a flexible hose. It particularly pertains to a hose used for the flexible connections in the cooling system of automobiles between the engine block and the radiator, but it is not limited to such use. It simplifies installation of a sight gauge for these and similar uses, and permits installation with simple basic tools.
