Allen Two-Motion Cone-Valve, Patent Model
Allen Two-Motion Cone-Valve, Patent Model
- Description
- This model was submitted to the U.S. Patent Office with the application for the patent issued to Horatio Allen, of New York, New York, June 19, 1855, no. 13075.
- The model represents a conical plug valve, connected to a valve gear, which gives it two distinct motions. The first motion is a slight one parallel with the axis of the cone and directed toward its larger end; the other is in a direction tending to rotate the valve. Because the valve and valve seat are conical, the first motion effects a very slight separation of the valve from its seat and permits the rotary motion to be given without friction upon those parts.
- Reference:
- This description comes from the 1939 Catalog of the Mechanical Collections of the Division of Engineering United States Museum Bulletin 173 by Frank A. Taylor.
