Readers may find that remarkable in of itself, however there is more.
The No 11 is still working some 170 years after it was invented by Mr O Connor further testament to our heritage, Victorian craftsmanship and ingenuity. If that was not enough there is still yet more.
On the back of Mr Patrick O Connors inventiveness and his skill in designing floor springs it brought him wealth, so much so he was able to have a number of houses built in North Drive, Wavertree, number 29 and number 31 (Urn House and Urn Mount). Which leads me on further still.
The reason why number 29 and number 31 are called Urn House and Urn Mount are because while these houses and another (number 27) were being built in the late 1860's some 8 prehistoric terracotta burial Urns (dating back 3000 years to the Bronze Age) containing human remains and arrow heads were discovered by workman digging the footings, two of which are now in the Liverpool Museum and are known as the Wavertree Urns, others are built into the walls of the properties above, number 27, Urn House and Urn Mount built for Mr O Connor on the back of his door spring inventions and the money generated by the sale of them.
Please feel free to leave positive comment if you have enjoyed reading about Irish born, Patentee, Ironmonger, Manufacturer, Inventor, Chair of Wavertree Local Health Board and Liverpolitan Patrick O Connor or his number 11 door spring.
