Those are some great words! Here's a few words/phrases I used in my novel that I picked up from
http://freepages.genealogy.rootsweb.ancestry.com/~poindexterfamily/OldWestSlang.html. There more Western phrases but time period appropriate for what I wrote.
Arbuckle's - slang for coffee from a popular brand of the time
flannel mouth - overly smooth talker
gospel sharp - a preacher
I also recently came across velocipede as a general word for pedal driven vehicles (unicycle, bicycle, dicycle, etc.).
