  • Patent number: 5758385
    Abstract: A cap for a broom has a shroud that simulates the appearance of the head of a straw broom and has front, rear, end and top walls defining an internal cavity. A cylindrical socket extends inwardly of the cavity from the top wall and may be threaded to receive the threaded end of a broom handle. A collar upstanding from the top wall provides additional support for the handle. An integrally moulded post projects into the cavity from the bottom of the socket and a nut, preferably a wing nut, is threadably secured to the post. The shroud can be filled with straws and a curable mass poured into the cavity to bind the straws together. The nut will be embedded within the curable mass as it cures and will prevent the mass and straws from coming out of the shroud during use.
