These may not be American slang but I still found them interesting. Immigrants would have been using these phrases in the 1870s and 1880s
"In 1909, writing under the pseudonym James Redding Ware, British writer Andrew Forrester published Passing English of the Victorian era, a dictionary of heterodox English, slang and phrase. "Thousands of words and phrases in existence in 1870 have drifted away, or changed their forms, or been absorbed, while as many have been added or are being added," he writes in the book's introduction. "‘Passing English’ ripples from countless sources, forming a river of new language which has its tide and its ebb, while its current brings down new ideas and carries away those that have dribbled out of fashion." http://mentalfloss.com/article/53529/56-delightful-victorian-slang-terms-you-should-be-using
