Yosef Karo

“ Paragraph 4 - If wine flows from grapes in a tub that had not yet been pressed, the droppings are not usable because the drinks that flowed out are forbidden, and therefore he is not permitted to put a dish underneath because he will disqualify the dish from being used for other purposes, [as it would now contain something forbidden] . ”

“ Paragraph 2 - If a barrel on the roof broke, he can bring a container and put it underneath, as long has he doesn't bring an additional container to collect the liquid in the air that fell off the roof and another container to connect to the roof. If he's using one container, it is allowed even to collect in the air or to attach to the roof.
סעיף ב - אם נשברה חבית בראש גגו מביא כלי ומניח תחתיה ובלבד שלא יביא כלי אחר ויקלט לקבל מן הקלוח באויר לאחר שירד מן הגג, ולא יביא כלי אחר ויצרף אותו לראש הגג. ואם מציל בכלי אחד, מציל אפלו קולט או מצרף. ”
