This is the main patent for the important Tyler turbine wheel, which was somewhat similar to the earlier but unpatented Francis turbine water wheel (see patent 39,562 for more on the Francis turbine). Tyler's subsequent improvements were issued as patent 20,456 (reissued as 3,018), 44,240, 52,625, 130,608, and 147,351. This present patent was reissued as 3,015 and then as 4,539, which was applied for and issued after this patent had expired. See that reissue for more information. |
