September 2, 200322 yr Admin Not long ago whilst going through a very old tome I found a drawing depicting a oxen powered trip hammer from an undisclosed age that was used to work metal ingots into smaller sizes that would have been shipped out. The book made no references to the age of the machine but clearly shows wooden cogs and gears with wood pegs holding the timber frame together. [*] A. Beam or Helve [*] B.A trunnions which supports the beam. [*] C.The hammer face. [*] D.Anvil face. [*] E.Anvil. [*] F.Trunnions [*] G.A metal strip called a shell or striker plate. [*] H.The power shaft or axle and hub [*] I.The toothed wheel. This could be adjusted by additions of teeth to strike at certain intervals depending on the metal being worked X.
