  • Patent number: 4829700
    Abstract: An animal trap discloses an elongated housing having open and closed ends, and a door pivotally biased to the closed position. A panel is disposed near the closed end of the housing and extends generally laterally within the housing above the bottom thereof. An elongated pawl member is connected at one end with the panel and is pivotally connected at its opposite end to the housing near the open end thereof. The pawl member has a tooth at its opposite end and is urged in an upward direction by a spring member connected thereto and in engagement with the bottom wall of the housing. The tooth is positioned to engage the door when it is moved to the open position to retain the door in the open position. The tooth is movable to a position wherein it releases the door to enable it to be moved to the closed position when an animal enters the housing and steps on the panel to pivotally move it and the pawl member downwardly.

  • Patent number: 4557067
    Abstract: An animal trap comprising an elongated housing having open and closed ends, a door pivotally mounted at its lower end on the housing adjacent the open end and movable between an upright closed position wherein it closes the open end and an open position wherein it is disposed within the housing in a substantially laterally extending position near the bottom of the housing. The door is biased to the closed position. A panel is pivotally connected at one end to the housing and extends generally laterally within the housing near the bottom thereof toward the closed end. An elongated pawl member is pivotally connected at one end with the adjacent end of the panel opposite to the one end thereof, and is pivotally connected at its opposite end to the housing. The pawl member has a tooth at its opposite end and is urged in an upward direction. The tooth is positioned to engage the door when it is moved to the open position to retain the door in the open position.
