The Artizan . smaller affairs than the regulators whichhave been spoken of for rendering the pressure uniform in large regulators for street lamps are, in fact, miniature governors applied tosingle lights. Like their larger prototypes they are all based on theoriginal idea of the governor, and, with trifling modifications, they mayall be described as miniature governors applied to single lights. Like the great station governor employed to regulate the pressnre ofgas into mains of the largest capacity, these miniature instruments allembrace the fundamental principle of a gas-holder provided with an inletand an outlet pipe, the former being furnished with a moveable cone actedon by the entering gas, just as in the larger machine. In some of the regulators, however, such as Suggs, and Paddons, andFords, the gas-holder is of the dry form, with flexible sides, such as havebeen made on the large scale for exportation and use in our colonies, and foreign countries. In others, such as Clybrans mercurial regulator, theholder is of the ordinary bell shape,and works in mercury instead ofwater. Fig. 1 is a full-sized represent-ation of the regulator designed andmanufactured by Mr. William Sugg,of Marsham-street, regulator was first adopted bythe Chartered Gas Company in theWestminster district, comprising theparishes of St. Margaret and the Evangelist. It has sincebeen largely adopted by the Imperial,the Western, and other companies. Description of Suggs Governor. A is the inlet pipe which screws on to the service pipe of the lamp orlantern. B is the conical inlet chamber. C is the half round ball-valve attached by a spindle to the top of thegas-holder, and which rises and checks the passage of the gas when thepressure increases, and, on the other hand, falls and admits more gas whenthe pressure diminishes. D is a metal disc forming the top of the miniature gas-holder. E is a flexible leathern cylinder enclosing the gas holder. F i
