Gas cylinder lifting device. 34-second video:

Found the patent with a search on the inventor's name at the wonderful but complex US Patent Full-Text and Image Database Advanced Search, with the search query: IN/(guerrero AND fred) AND APT/1. That's IN for inventor name, and APT/1 means utility patents, as opposed to design patents or plant patents.
