Vintage 1905 Juice O Mat

Have you ever heard of a Juice o Mat? I found one this morning at a garage sale. I went to lift it off of the table and it was heavy...no aluminum here! It had a beautiful retro look and it seems functional. I looked around on the internet an apparently folks collect this item but there doesn't seem to be much history on the piece. I wish the Rival Company would create a product history on their web site. I definitely would like to learn more.
