STRIKER LIFTING MEANS FOR TRAPS
An added lever so the trapper never touches the dead mouse.
The trap operates as an ordinary snap trap: the mouse depresses the bait plate, the latch releases, and the spring-driven striker flies over onto the animal. A separate wire rod passes through the coil spring and mounting staples, carrying an inclined arm that lies beneath one side of the striker and ends in a finger piece outside the striker's path. The trapper presses down on the finger piece; the inclined arm rises and lifts the striker off the animal, which drops free without being handled. The same arm may be used to raise the striker when setting the trap.
“The general object of the present invention is to provide means whereby the striker may be released or lifted from the stricken animal without the fingers of the trapper's hands touching the animal”— Carey E. Bunker, from the specification
