Not illustrated. 1907 Excerpt: ...exerted by a float in such a manner as to cause it to operate a valve, permitting steam pressure to act upon a diaphragm, the movement of which, due to its flexibility, in turn opens the main discharge valve. Dealing with the design in detail, the body or box consists of a strong cast-iron chamber, each part being of more than ample strength and rigidity for the purpose in view. As will be seen, the upper half of this casting is of about half the diameter of the lower portion, and is continued downward towards the bottom, thereby forming a cylindrical-shaped compartment, the bottom or inner half of which serves to maintain the float in position and acts as a guide for it, whilst the upper half contains the valve-operating levers. In the left-hand top corner will be noticed a separate little box, containing two small valves, bolted to a flange on the side of the body, and having a thimble connection at the top leading to a dome-shaped casting. This dome-shaped casting contains a specially-constructed flexible diaphragm, which, when acted upon by the steam pressure in the system under drainage, depresses the valve and holds it hard on to its seating, thereby preventing the escape of the contents of the trap. But when this flexible diaphragm is relieved of the steam pressure, the valve is released and opens, under the influence of the pressure acting upon its under face. It is now perfectly evident from the above that, in order to obtain a controlled discharge, some means must be adopted by which the up-and-down motion of the float alternately releases and admits steam pressure into this diaphragm chamber, so as to open or close the discharge valve. This is obtained in the following manner: When the float is in the position shown in fig. 37 the discharge valve...
