173,489. Anciens Etablissements Barbier, BÚnard, et Turenne. Dec. 24, 1920, [Convention date]. Clockwork - - actuated valves; fluid - actuated valves.-A clockwork-actuated valve particularly adapted for use with beam lights is fitted with mechanism for winding the clockwork actuated by the flow of gas to the pilot burner. The main hinged valve 39 is loaded by a tumbler spring 38 and is actuated by a fork 36 on a spindle 32 provided with a second fork 33 mounted on a spindle passing through a stuffing box having a gland in the form of a circular wedge and adapted to be engaged by adjustable face cams 37 on a 24-hour dial 34. The clockwork is wound by an oscillating lever 22 carrying a pawl adapted to engage a rachet wheel 23 acted on by a spring 29 so as to engage frictionally a disc 24 mounted on the winding arbor 23a. The lever 22 is actuated against the action of a spring 26 by the pressure of the gas passing to the pilot burner acting on a diaphragm 5 connected to the lever by an adjustable strut 25. Gas is alternately admitted to and exhausted from the diaphragm chamber B through a two-way hinged valve 13 loaded by a tumbler spring mechanism 11c and actuated by tappets 9, 91 on a spindle 7 carried by the diaphragm engaging a projection 10 on the tumbler. To supply the burner while the chamber B is being filled a reservoir having elastic walls loaded by springs is arranged between the outlet from the chamber B and the burner.
