The circuitMng closed by the liquid, the magnet, 17, attracts theI mature, 27, which raises the end of the lever, 11, andlifts the compressed fluid inlet valve, 7, which is normallyclosed by the weight of the lever. The compressed fluidenters the vessel, 1, through the pipe, 5, closes the airescape-valve, 8, against the spring, 14, and forces theliquid out of the vessel through the rising main, 2. Inorder to pievent the circuit being broken as soon as the. level of the Uquid falls below the contact. 15, a conductingwire, 20. insulated at 32. dips into the liquid in the vessel,the depth to which it enters the vessel being adjusted bythe sleeve contact, 40. This is connected by the rod,21. to the sUding contact. 22, attached to the hinged , which is connected by the rod, 28, to the armature, the circuit is closed, the arm, 25, is lifted by thearmature and the contact, 23, is brought against thecontact, 24, and remains in this position until the level ofthe liquid falls below that of the bottom of the wire, this happens the circuit is broken and the armature,27, drops, closing the valve, 7, and separating 23 and vessel, 1, then commences to fill again.—W.
