you could try the Adelung (http://woerterbuchnetz.de/cgi-bin/WBNetz/wbgui_py?sigle=Adelung). It is 18th c. German, but it should not contain poetic contractions. It also was the basis of the morphological analyzer developed in TextGrid (Morphisto), but probably using abridged orthography. Furthermore, check http://www.woerterbuchnetz.de/cgi-bin/WBNetz/setupStartSeite.tcl, the Goethe dictionary or Grimm may be applicable.
Neither dictionary is directly available in machine-readable form, but you may contact the Trier Center for Digital Humanities for the XML sources or just scrape the generated HTML (if that's allowed in your legislation -- for Germany, the new UrhWissG allows to use up to 75% of a resource *for your own scientific research* [but disseminate only up to 15%]).
Suggestion: Use the Adelung for 18th c. German and maybe Grimm for pre-Duden 19th c. German, write expansion rules for contractions (there should be very few such rules, mostly e-insertion as in your examples) and double-check whether your rules hit anything in the dictionary.
