Capito
Rat and Mouse Trap (From The Ironmonger, 1900)
This advertisement clearly demonstrates the way in which the perpetual mousetrap
works, described as the "Greatest Success of the Century". Bait is placed
just inside the door. The rat or mouse is lured in. The weight of the mouse
on the platform inside the door releases a hook that closes the door, trapping
the mouse inside. As its exit has been blocked the mouse is forced onwards
and upwards to the top of the trap. At the top of the trap the mouse topples
into the canister of water below and drowns. However, at the top of the
trap is a device connected to the front door by a wire. As the mouse falls
to its death it operates the device which opens the door for the next unsuspecting
mouse. |
