Patent GB-189819402-A (GB)
Title: Improvements in Water-feed Apparatus for Boilers.
Inventor: WEISS FRANZ JOSEPH
Filed: 1898-09-12
Granted: 1898-11-19
Abstract: 19,402. Weiss, F. J. Sept. 12. Feed-pumps.-To maintain an approximatelyconstant water level in a steam boiler, the steam pipe of an independent feed-pump is arranged to deliver water to the pump, instead of steam, when the level rises above the normal. In the arrangement shown in Fig. 1, the steam pipe a of the pump D terminates within the boiler at the normal water level. Should the water rise above this level, it passes to the motor cylinder of the pump, and keeps it slowly working, the exhaust water passing to the feed-tank F. A branch, with a stop cook, allows steam to be admitted to work the pump at any time if desired. Fig. 4 shows a modified arrangement adapted to prevent scum from entering the pipe a, and also to allow the pump to go on working with water a short time after the water in the boiler has fallen below the ordinary level. The latter object is affected by means of the vessel g enclosing the open end of the pipe a. In other modifications, the chamber g is dispensed with, while the outer chamber k is retained ; or a chamber corresponding to g is used alone, being connected at its upper end with the boiler at the water level.
