The Patent Shaft and Axeltree Company Est 1840



" Buenos Aires Transporter Bridge"


During our research we have uncovered the following information which I feel will place a different light on the Patent Shaft gates and I am sure surprise all that read the article.

I do hope the councilors who will be deciding the fate of the gates that so many passed through appreciate the achievements they made and history the Patent Shaft has.

Many thanks goes to the great grandson of Graham Harris

P.S. I believe that my grandfather, Henry Lionel Harris, came to Argentina as an engineer, contracted for the construction of this bridge.




Our history is being eroded just like these gates, please help me to restore these gates and the history they stand for.

If you have any comments or maybe a bit of history about the Patent Shaft then please email to the address below. I will endeavor with your help to restore these gates and hopefully the memories they represented.
