Abstract

28,994. Dewrance, J. Dec. 19. Water levels, indicating.-In low-water alarm apparatus in which a valve c<2> is operated by a float d<1> to open communication between the boiler and an alarm signal attached to the tube b<8>, the pivoted end of the valve stem c is provided with a cap c<3>, which, in conjunction with a lip b<1> depending from the interior of the boiler shell, forms a trap for maintaining a column of condensation water within the chamber b, thus normally protecting the valve c<2> and seating c' from the action of high-temperature steam. By means of the bell-crank e and rod e', the apparatus can be blown through when desired.
