  tilt…hammer　of　considerable　power；　which　he　at　first　worked　by　means

  fly…wheel。　　His　first　hammer　of　this　kind　was　120　lbs。　in　weight；　it

  a　tilt…hammer　for　Mr。　Wilkinson　of　Bradley　Forge；　of　7　1/2　cwt。；　and

  applying　to　it　the　force　of　steam；　at　once　provided　the　worker　in
  iron　with　the　most　formidable　of　machine…tools。　　This　important
  invention　originated　as　follows：
  In　the　early　part　of　1837；　the　directors　of　the　Great　Western
  Steam…Ship　Company　sent　Mr。　Francis　Humphries；　their　engineer；　to
  consult　Mr。　Nasmyth　as　to　some　engineering　tools　of　unusual　size　and
  power；　which　were　required　for　the　construction　of　the　engines　of　the
  〃Great　Britain〃　steamship。　　They　had　determined　to　construct　those
  engines　on　the　vertical　trunk…engine　principle；　in　accordance　with
  Mr。　Humphries'　designs；　and　very　complete　works　were　erected　by　them
  at　their　Bristol　dockyard　for　the　execution　of　the　requisite
  machinery；　the　most　important　of　the　tools　being　supplied　by　Nasmyth
  and　Gaskell。　　The　engines　were　in　hand；　when　a　difficulty　arose　with
  respect　to　the　enormous　paddle…shaft　of　the　vessel；　which　was　of　such
  a　size　of　forging　as　had　never　before　been　executed。　　Mr。　Humphries
  applied　to　the　largest　engineering　firms　throughout　the　country　for
  tenders　of　the　price　at　which　they　would　execute　this　part　of　the
  work；　but　to　his　surprise　and　dismay　he　found　that　not　one　of　the
  firms　he　applied　to　would　undertake　so　large　a　forging。　　In　this
  dilemma　he　wrote　to　Mr。　Nasmyth　on　the　24th　November；1838；　informing
  him　of　this　unlooked…for　difficulty。　　〃I　find；〃　said　he；　〃there　is　not
  a　forge…hammer　in　England　or　Scotland　powerful　enough　to　forge　the
  paddle…shaft　of　the　engines　for　the　'Great　Britain！'　What　am　I　to　do？
  Do　you　think　I　might　dare　to　use　cast…iron？〃
  This　letter　immediately　set　Mr。　Nasmyth　a…thinking。　　How　was　it　that
  existing　hammers　were　incapable　of　forging　a　wrought…iron　shaft　of
  thirty　inches　diameter？　Simply　because　of　their　want　of　compass；　or
  range　and　fall；　as　well　as　power　of　blow。　　A　few　moments'　rapid

  by　steam；　was　but　a　modificationthat　the　difficulty　had　arisen。
  When　even　the　largest　hammer　was　tilted　up　to　its　full　height；　its
  range　was　so　small；　that　when　a　piece　of　work　of　considerable　size
  was　placed　on　the　anvil；　the　hammer　became　〃gagged；〃　and；　on　such　an
  occasion；　where　the　forging　required　the　most　powerful　blow；　it
