Obscure Cultural Trivia Contest: The Demon

I just got back from the Allgäu and/or upper Swabia, and quite enjoyed it. Some comments as time permits. For now, your mission is to identify this object:

Ye Gods, my tongue has been fused to my lower jaw!!

A few hints: it was made in 1730, and has a very specific purpose in the manufacture of a pretty common thing that is still very much in use today.

UPDATE: Kudos to Mathias Warkus, who correctly identified this as a spout for bran during the milling process. During the milling, the bran, which nobody wanted to eat in their bread back in 1730, was pushed to the side and fell out of this demon's mouth. The German name for this object is Kleiekotzer, 'bran-puker.' I spotted it in the German Bread Museum in Ulm, one of the many ludicrously specific small museums in Germany (including the German Packaging Museum in Heidelberg and the German Blade Museum in Solingen).
