Automatic battery water filler

摘要

A lightweight acid-resistant plastic dispenser having a handle housing enclosing a valve and valve-operating mechanism and remote therefrom on a rigid tubular extension a plastic water nozzle and a flexible hose connected to a water source. The nozzle of the dispenser has two ducts, one for water and the other for aspirated air to produce a suction when the level of the liquid in the battery cell being filled reaches the lower end of the nozzle. The aspirated or suction air operates a diaphragm to break a toggle in the valve-operating mechanism, automatically shutting the water valve in the handle housing. The valve control mechanism in the handle comprises a double toggle composed of three alignable links which when aligned operate against the normally spring-pressed water valve to hold it open. The alignment of the links is performed by a manual plunger operated by the operator's thumb and comprises two longitudinally relatively movable parts, one pivoted to one of the intermediate links and is lockable in operating position, and the other abuts the central link and is free to move longitudinally. An adjustable lever connected to one end of the diaphragm in the housing and abuttable at the other end with the other intermediate pivot of the links, breaks the toggle when the suction occurs at the nozzle.
