Here’s something a friend uncovered: Guide to the United States for the Jewish Immigrant, published in 1916.
Besides providing helpful information about transportation options in the US, the benefits of farming as a profession, and how to become a citizen, it includes legal advice; bigamy, spitting in public, and beating or shaking a rug are illegal. The second of these, spitting, is also disgusting.
It advises, “The Jew, like any other foreigner, is appreciated when he lives the American social life. Until then he counts for nothing.” Though it also urges, “Be proud of your race, your birth and your family, a Jew is all the better an American for being a good Jew.”

Rug beating? What was that about?

Sounds odd, doesn’t it? I can only guess it relates to something that was still common in Poland until recently. Since no one had a vacuum,they would be hung outside and beaten with a rug beater to get all the dust out.
