Abstract
An industrial animal trap is provided to effectively, continually, and rapidly exterminate rodents, pigeons, and other animal pests in an efficient and safe manner. The animal trap has a feeding chamber, a killing chamber, and an optional discharge chamber, which are separated by moveable walls. In the preferred form, the chambers are in horizontal alignment and the animal trap has a horizontally moveable front wall which sequentially pushes the animal from the feeding chamber to the killing and discharge chambers.

An animal trap, comprising:
- a feeding compartment for attracting an animal with the aroma of bait, said feeding compartment defining an access opening for ingress of said animal into said feeding compartment;
- a killing compartment positioned in generally lateral alignment with said feeding compartment;
- killing means operatively associated with said killing compartment for killing said animal in said killing compartment;
- intermediate wall means being moveable from a normally closed position extending between and separating said feeding compartment from said killing compartment to an open position substantially out of said compartments;
- and
- drive wall means being moveable from one position providing the end wall of said feeding compartment when said intermediate wall means is in said normally closed position to said normally closed position of said intermediate wall means when said intermediate wall means is in said open position to move said animal into said killing compartment.

An animal trap, comprising:
- a feeding chamber defining an access opening for entrance of an animal and bait passageways for passage of scent of a bait to attract the animal into the feeding chamber;
- a killing chamber communicating and positioned in substantial horizontal alignment and registration with said feeding chamber;
- a discharge chamber communicating and positioned in substantial horizontal alignment and registration with said killing chamber for discharging animals killed in said killing chamber;
- said feeding, killing, and discharge chambers having a common, substantially coplanar horizontal ceiling and a common, substantially coplanar horizontal floor;
- an intermediate vertically moveable, power-driven vertical wall being moveable from a normally closed position extending between and separating said feeding and killing chambers to an upward open position generally outside of said chambers;
- a vertically moveable, power-driven, vertical end wall being moveable from a normally closed position extending between and separating said killing and discharge chambers to an upward open position generally outside of said chambers;
- a power-driven front vertical wall being horizontally moveable from an initial position providing a front wall for said feeding chamber when said intermediate wall is in said normally closed position, to an intermediate position occupying the normally closed position of said intermediate wall when said intermediate wall is raised in said open position to push said animal into said killing chamber, to an end position occupying the normally closed position of said end wall when said end wall is raised in said open position to push the killed animal into said discharge chamber;
- and
- a set of vertical, power-driven spikes for entering into said killing chamber when said front wall is in said intermediate position to impale said animal.
