  • Rat or mouse trap
    Patent number: 4662101
    Abstract: A mousetrap (10) is made of a pivoting platform (12) suspended over a pitfall (14). The platform (12) is balanced in a manner such that it normally assumes a horizontal position, thus giving a mouse an appearance of a stable bridge over the pitfall. When the mouse (42) steps onto the platform (12) for the purpose of obtaining bait placed thereon, however, the platform (12) spins and dumps the mouse into the pitfall thereby trapping it.
