Abstract: A rattrap installation which includes a detector as well as power driven executing member for performance of successive operations after an automatic removal of previously executed rats. A device is provided for releasing a bait scent for a predetermined period of time and a steep climbing element extends vertically downwardly from the trap and has a length of several times a body length of the fully grown rat. The executing member is disposed at a position corresponding to a location of a neck region of the rat when a nose of the rat is located in a release area of a bait scent. A built-in energy source is provided in the trap for enabling an activation of the executing member a large number of times.

Abstract: A rodent trap that is constructed with a housing having a rodent entry and containing a launching mechanism that is activated by a photo sensor when a rodent enters the housing, the launching mechanism ejecting the rodent through an opening in the top of the housing and into a receptacle for disposal.

Abstract: An electric mouse trap is provided and consists of a solenoid powered by an electrical circuit mounted in a housing. The solenoid has a movable plunger pivotally connected to end of a trapping lever. An electric switch is carried on bottom of the housing under the trapping lever and is electrically connected to the circuit. A mouse entering an access opening in the housing will eat bait on the switch so that the switch will close activating the solenoid moving the trapping lever down onto the mouse.

Abstract: A mouse exterminating device and method is presented with improved safety features. Activated electrical circuitry causes the mouse to be suffocated by impingement of a horizontal blade while a thermal switch prevents the device from overheating thus reducing the chance of fire. Indicator lights demonstrate whether the device is turned on and also if the device has been activated by a mouse.

Abstract: A rodent trap characterized by a rodent receiving chamber, a partition selectively movable across the chamber in a rodent eradicating relationship, a movable floor portion continually urged to an overlying position with respect to a rodent receiving tray, where the floor portion moves with the partition and cam action releases the floor portion to the aforesaid overlying position. A pressure sensitive switch holds the rodent bait and initiates sequential operation. The trap further employs a two-way solenoid for partition movement and a one-way gearing arrangement for selective floor portion position control.

Abstract: A power operated rodent exterminating apparatus includes a pneumatic actuator for moving a pivotally mounted striking bar from a retracted position to a striking position and automatically returning to a retracted position. A detector plate is mounted on the apparatus frame in the path of the movement of the striking bar to a striking position in contact with a portion of the frame. Ejector mechanism including pivotally mounted opposed gate members are operable upon retraction of the striking bar to sweep the detector plate to clear a rodent therefrom. A control circuit is operable to sequentially effect actuation of the striking bar and the ejector mechanism and to repeatedly cycle the ejector mechanism until the detector mechanism is reset.

Abstract: A rodent exterminating apparatus having a frame on which a pivotally mounted striking bar is operable to be moved from a retracted position to a striking position by a pneumatic actuator including a one way spring return rolling diaphragm operated plunger. The actuator is operated by a pneumatic control circuit which senses the presence of a rodent to cause a fast acting valve to direct pressure air to the actuator from a reservoir chamber which is formed as part of the actuator. The control circuit includes a pneumatic time delay device which automatically moves the control valve to reset the striking bar after a predetermined period of time commencing with deactivation of a trigger or proximity sensor in the control circuit.
