Abstract
Abstract A steam trap for collecting condensate from a steam line comprising a housing having an internal conduit system which includes a glass cylindrical structure connected across a lateral passage through said housing which allows for viewing of the liquid level or condensate level within the steam trap. A strainer is included in the device to filter out impurities within the condensate. An adjustable valve is provided to regulate the flow of condensate therethrough.

304 words
A condensate drainer in which the internal level of the condensate may be visually determined and is manually maintained comprising: a housing of unitary construction, said housing having a steam inlet condensate chamber, and a condensate outlet chamber, a vertical passage in communication with said inlet chamber, said vertical passage opening at its upper end into said inlet chamber, a vertically disposed cylindrical chamber coupled at the bottom in communication with said vertical passage having an enlarged radius the inside surface of which is disposed concentrically outside of said vertical passage end, said housing having a lateral passage disposed therethrough, the lower edge of said vertical cylindrical passage opening into said housing lateral passage, a second vertical passage axially in line with said first vertical passage opening into the diametrically opposite side of said housing lateral passage, a strainer chamber in communication with said second vertical passage, a cross-over conduit, a third vertical passage, said cross-over conduit connecting said strainer chamber with said third vertical conduit; and a tubular glass conduit connected into said housing upper end into the first vertical passage in a fluid-sealed manner having its lower end received into said strainer chamber with portion of said glass cylinder conduit in contact with said second vertical chamber whereby a portion of said glass conduit disposed within said housing lateral passage is observable from said front face and said rear face of said housing; a threaded plug coupled into said straining chamber; a strainer disposed within said strainer chamber, held in position by said plug; an adjustable valve means separating said third vertical chamber from said outlet flow chamber, said valve movable from an open position allowing for communication between third vertical chamber and said outlet chamber to a closed position stopping fluid communication between said third vertical chamber and said outlet chamber.
