Can anyone help me to identify the use and the origin of this glassware?

I recently bought this from the auction. Painting on the case seems to be hand painted and there is a mark in the bottom “Pat. Appld. For”.

I wonder the usage for this glassware and year of it origin?

Thank you!


  • Why could there not be a patent number!!

    I guess there must have been some inserts in the two round openings. I am unsure of its original use.
