Abstract

12,871. Clark & Co., A. C., and Clark, A. C. May 25. [Addition to 10,428/12, Class 81 (ii), Medical &c. appliances.] Pressure regulating and reducing valves.- The inhalation apparatus described in the parent Specification, for administering a mixture of two gases, is fitted with a pressure-regulating valve which is controlled by the inflation of a gas-bag acting through levers 48, fulcrumed on a flanged collar 51 and operating the valve through rods 46 and a frame 45. The sliding plug 38 of the regulating-valve is furnished with a valve seat 40 of fibre or like material which presses, when closed, against the inlet nozzle 36. The valve is normally held open by a spring. A plug 42 sliding in the lower part of the plug 38 is controlled by a stiff spring 43 and allows further movement of the levers 48 after the regulating-valve has been closed when the direct supply of gas to the gas-bags is employed. The flange collar 51 is adjustable so that the pressure for which the regulating- valve is set may be varied.
