Description:

1. Valve. A plate of metal ground flat on one or both sides and enclosed within a metal box, having one or both sides ground for the valve to slide against. The valve is fixed in a frame or pair of forceps, with a rod passing through a stuffing box, and hangs free and takes its seat against the side of the box by the pressure of the steam only.

2. Passes worked steam through heated tubes, or other vessels, to heat other substances, and fixes a valve, near the escape passage of the steam, so loaded as to produce a counter pressure against the escape side of the piston of a compression engine to boil with the worked steam at a higher temperature than 212° F.
