This design sounds worthy of making... http://www.bbc.co.uk/news/uk-england-berkshire-35503613 A number of unique and intriguing mousetraps have been designed throughout history. The best are true marvels of engineering, beautiful in their mechanical simplicity. One of the greatest has to be the Perpetual Mouse Trap patented by Colin Pullinger & Sons in 1861. The model that the Museum of English Rural Life (MERL) in Berkshire, UK has on display just caught a mouse without any bait. The staff at MERL came in Wednesday morning to an email from an assistant curator that read: "There appears to be a dead mouse in this mousetrap, which is not described as being there on the database." As Pullinger & Sons claim right on the trap, it will indeed "last a lifetime." BugBear |

Paul, Where would we get enough information to make a dimensioned drawing? I'm not familiar with British patents - would there be patent drawings ? John Ruth |

Here is a article in the Sussex Industrial History journal that has about everything you would ever want to know about Pullinger's mouse trap. No dimensioned drawings however. sias2.pastfinder.org.uk/sih_1970_2008/24-1994.pdf ~~~~~~~~~~~~~~~~~~~~~~ Bob Page in da U.P. of Michigan ________________________________ From: paul womack |

Nothing in the European Patent Database http://worldwide.espacenet.com/searchResults?ST=singleline&locale=en_EP &submitted=true&DB=worldwide.espacenet.com&query=colin+pullinger">http://worldwi de.espacenet.com/searchResults?ST=singleline&locale=en_EP&submitted=true&DB=worl dwide.espacenet.com&query=colin+pullinger Might be a bit too old.

Got this by googling patent pullinger colin And bypassing all the current news. Also, it has not been digitized apparently. http://discovery.nationalarchives.gov.uk/details/r/C14036653 Kirk in HMB, CA |

paul womack wrote: > This design sounds worthy of making... The book Kirk linked to (Animal Traps and Trapping, by James A. Bateman, 2003) has a worrying statement; "When the patent for this trap expired, many imitations appear to have been marketed, but mostly these were inefficient compared with the original. An acceptable variation was made for a number of years by the firm of Duke, Waring, Crisp & Co, at the Soho wireworks, in London." Now, the makers of the the "inefficient versions" presumably had access to the originals, ad could make a close copy, and yet they still failed. This leads to me to suspect two possibilities * they cheapened the manufacture by cutting corners that lessened the operational quality * the original is simple in principle, but the the details, sizes weights etc all need fine tuning to work well. It could be both, of course. The second reason would be a strong objection to creating a reproduction based on diagrams "in principle", and an overall shot from the web. Which is all the information we currently have :-( BugBear |
