摘要： 12,462. Still, W. M., and Still, E. H. June 1. Reducing-valves.-Relates to a pressure-reducing valve wherein the valve is controlled by two pistons or diaphragms, one being constantly subjected to the inlet pressure and tending to close the valve, the other being acted upon by a spring or its equivalent and tending to allow the valve to open freely. The valve comprises a casing 1, in the opposite walls of which are two diaphragms 4, 5 which are preferably made of thin metal with concentric corrugations. At the rear of the smaller diaphragm 4 is a chamber 6 which is in permanent communication through a passage 7 with the inlet branch 2. The larger diaphragm 5 is pressed towards the smaller one by the helical spring 11, the compression of which may be varied by turning the screw-threaded plug 12. Within the casing is a bell-crank lever 8, one arm resting on the diaphragm 4 and the other bearing against the inlet valve 9 of the form described in Specification No. 12,461, A.D. 1904. Between the diaphragms is a rod 13, one end being recessed to receive the conical projection 5 of the larger diaphragm, the other end being forked and engaging with a pin 21 in the bell-crank lever. When the outlet pressure falls below the normal, the spring 11 causes the larger diaphragm to be displaced towards the smaller diaphragm, the movement is transmitted by the rod 13 to the bell-crank lever, and the valve 9 is free to open under the inlet pressure. Upon the outlet pressure increasing, due to the admission of fluid past the valve, the larger diaphragm 5 is forced outwardly in opposition to the spring 11, the smaller diaphragm is relieved of the pressure transmitted by the rod and is displaced inwardly by the highpressure fluid in the chamber 6, and causes the bell-crank lever to be turned, causing the valve to close and admit less fluid. In a modification, the inlet and outlet branches are at right-angles, the inlet branch being opposite the smaller diaphragm. The latter is connected to the valve by a rod which is controlled by a bell-crank lever worked by the larger diaphragm. In a further modification, the arm of the bell-crank lever is considerably lengthened, and works with a rod attached to the spring-controlled diaphragm. A block connected with the high-pressure diaphragm presses against the long arm of the lever with less leverage than the larger diaphragm. Pistons may be used in each case instead of flexible diaphragms.

摘要： 12,461. Still, W. M. June 1. Lift valves; seats. -Relates to a valve suitable fox stop - cocks, taps, steam traps, and the like, so designed that it is little liable to damage when screwed down with excessive force, and acte efficiently when the valve spindle is slightly out of alignment. The valve body is formed with a partly spherical end portion 1 , provided with a bead or shoulder 1 and fitted with a flexible facing 2, which is stamped, pressed, or otherwise formed out of thin metal. The facing may be approximately conical, spherical, or cupshaped, and is provided with a flange 2 so that it may be secured to the shoulder 1 , forming an airtight space which may contain air, gas, or a volatile spirit. The metal seat 3 is made with an abrupt edge 3 . In consequence of the limited flexibility of the valve, it has a tendency to settle into the seat with good contact even though the spindle is slightly out of alignment. If the valve is screwed down too tightly, the face will be nipped between the valve body and the seat and the resulting damage will be slight.

摘要： 26,171. Jones, C. J., and Still, W. M. Nov. 27. Water - heaters, gas.-Relates to a vertical boiler, with automatic regulation, for heating water for use in making tea, coffee, &c. The boiler is heated by a gas burner b, the flames from which pass up vertical tubes c arranged i n t h e water space of the boiler and opening into a common chamber c leading to the chimney d. The gas supply is regulated by a valve h carried by the lower of two corrugated metal discs j forming an enclosed chamber k which is in communication with the steam space of the boiler. A bye-pass prevents the gas from being entirely shut off from the burner.

摘要： 3177. Jones, C. J., and Still, W. M. Feb. 12. Lighting and extinguishing gas.-A diaphragmactuated valve for controlling the supply of gas to a gas burner having two valves, one controlling the supply to the main burner, the other the supply to the pilot burner, is provided with a permanently open passage to the pilot burner. In the form shown in Figs. 1 and 2, both valves m, i are of the lift type and are mounted on a single valve stem operated by a diaphragm e. The by-pass is supplied, when the main valve i is closed, through the valve. m and a passaged o adjusted by a screw r. When the main valve is open, the by-pass is supplied through a passage s adjusted by a screw t. In a modification, a check valve controls the supply to the main burner while the pilot valve alone is controlled by the diaphragm. In another modification, the two valves are mounted on a rocking lever oscillated by the diaphragm which is loaded by an adjustable spring.
