Bramwell Valve, Patent Model

Description
This model was submitted to the U.S. Patent Office with the application for the patent issued to William Bramwell, of New York, New York, June 14, 1859, no. 24639.
The model represents a valve in which a gate swinging upon a horizontal axis is opened or closed by means of a band wheel, vertical screw, and toggle link.
The gate of the valve is a conical plug that swings on an arm from a pivot above it. When closed the gate fits a conical seat in the valve body; when opened it swings up into the top of the valve body practically clear of the passages. The peculiar feature of the valve is the arrangement of parts, which permits the closing of a swing-gate valve by means of a hand wheel and screw.
