A Leffel turbine in a casing

Not selected for Google Earth or Google Maps [?]

This is a turbine and casing very much like that used by the Tamaiti Gold Sluicing Co. It doesn't show the turbine so well - it is visible with its shaft horizontal to the right of the casing seen through the penstock opening. The discharge tube is curved down to the right and would have for best effect have been connected to a reasonably long (10') draft tube - a way of exposing the turbine to "suction" on its discharge face. On the discharge casing can be seen the output shaft powered gearing that drove the governor and the rack and pinion that kept the wicker gates at a position to either maintain power or maintain revs/minute depending on what the turbine was used for. This apparatus is mainly missing from the Tamaiti turbine as it now can be seen.

Panoramio's terms of use specifically excludes pictures that are not your own, pictures taken indoors and pictures of machinery. I have had contact with the site moderators who however have agreed that the pictures maps old photos etc which I am publishing and particularly machinery in-situ and "on the ground" will be accepted and occasionally end up on Google Earth because they are supportive of Panoramio and Google earth being utilised like I am using it to elucidate and explain heritage - I'm very pleased as you might guess.
