The link to William Ketchum leads to the 20th century U.S. Congressman, not the inventor of the hand grenade.

Mayor of Buffalo, NY Reference Appears Incorrect

[edit]

Posted October 29, 2014

William Ketchum (no initial) was the Mayor of Buffalo, NY in 1844. William F. Ketchum (also of Buffalo, NY) was the inventor of the Ketchum Grenade, patented on August 20, 1861 via U.S. patent number 33,089.

These are two different men, and their relationship (if any) is not known at this time. Please remove the reference to William F. Ketchum being mayor of Buffalo, NY because that information appears to be incorrect.

If you refer to Walker’s Buffalo (NY) City Directory of 1844, published by Horatio N. Walker, you will see these two men listed on page #136 as immediately below (edited for clarity).

- Ketchum, William; mayor; hat store at 202 Main St.; home at 52 East Seneca St. (all Buffalo, NY)

- Ketchum, William F., jeweler at 59 Huron St.

William F. Ketchum was a talented inventor, and he patented the landmark Ketchum Mower on November 18, 1844 via U.S. patent number 3831. The Ketchum Mower was considered a significant milestone in agricultural-machinery history because it was considered to be the first machine which only mowed (e.g., hay, wheat, grass). Prior to the Ketchum Mower there was only the Reaper, which mowed and reaped (combined). William F. Ketchum licensed many firms to manufacture his Ketchum Mower.

In field trials the Ketchum Mower often perform well against other mowers. The several firms which were licensed to manufacture the Ketchum Mower continued to improve upon its basic design.

Other U.S. patents held by William F. Ketchum (a.k.a. Wm. F. Ketchum) of Buffalo, NY include, but are not limited to, those listed below.

U.S. Pat. #1,107 Mode of Ascending and Descending Inclined Planes on Railroads of Mar. 20, 1839

U.S. Pat. #2,085 & 33,089 Improvement in Hand-Grenades of Aug. 20, 1861

Thank you for making the above-requested change. A special page devoted to the Ketchum Mower would be a good idea because of its significance in the history of agriculture and agricultural machinery.
