Mouse trap designs
[edit] Spring-loaded bar mousetrap

Mousetrap, mouse, bait (chocolate)
The first spring-loaded mouse trap was invented by William C. Hooker of Abingdon Illinois, who received US patent 528671 for his design in 1894.[1][2] James Henry Atkinson, a British inventor who in 1897 invented a prototype called the "Little Nipper", probably had seen the Hooker trap in the shops o
r in advertisements and used it as the basis of his model.[3]
The traditional type was invented by Sir Hiram Stevens Maxim (who also invented the Maxim gun). It is a simple device with a heavily spring-loaded bar and a trip to release it. Stereotypically, cheese is placed on the trip as bait. Other food such as oats, chocolate, bread, meat, butter and peanut butter are also effective. The spring-loaded bar swings down rapidly and with great force when anything, usually a mouse or a rat, touches the trip. The design is such that the mouse's neck or spinal cord will be broken, or its ribs or skull crushed, by the force of the bar. Rats can easily escape from a mousetrap, so a larger version is used for them. Newer spring mouse traps have a plastic extended trigger made to look like a piece of Swiss cheese that is the color of American cheese.
John Mast of Lititz, Pennsylvania obtained an American patent for a similar snap-action device in 1899.[4]
Some modern plastic designs have the advantages that the trap can be set by the pressure of a single finger on a tab and that a dead mouse can be removed from the trap without touching the corpse.
