The point of Gannon’s invention was to make it easier and less expensive to secure slates or tiles to roofs. He developed a method of attaching "slates or tiles to the roofs of fire-proof buildings" more quickly and securely without "necessitating the perforation of the slate or tile and the use of nuts or screws."
