Abstract
A mole trap includes a steel rod frame having parallel spaced legs adapted to penetrate the ground on opposite sides of a mole hill or tunnel. The legs are integrally connected by a handle portion and also by a stop bar, and a spike plate having depending spikes is preloaded against the stop bar by compression springs mounted on the legs. An L-shaped latch lever is pivotally supported by the stop bar and supports a trip plate adapted to contact the ground where the mole tunnel has been depressed. The spike plate and spikes are retracted upwardly against the springs to a set position by pulling a flexible strap extending from the handle portion around a roller supported by the spike plate for rotation on an eccentric axis to provide a mechanical advantage. A roller on the latch lever automatically blocks the spike plate when elevated to the set position.
