What are these things??

Recommended Posts

OK, we dragged these two objects out of the scrap but we don't know what they are. We put them near our railway siding and people have been asking what they are. I need to put a signboard on them.  Nearest we can figure is that they are presses or filters of some kind. Highly likely they have a connection to the mining industry. Any idea what they are?

Plate filter. Some wineries use them. image.png.5e4561aea720cf6b3b1a8674fd5df6c9.png


I saw them being used at  some of the wineries I did work for. Breweries also use them. Basic design where you add or subtract the number of plates depending on what and how clean you need.

The filter media is missing.

Woody! You have nailed it! It is quite likely they were used in the sugar industry, as I know quite a lot of our stuff came up from the Innisfail area. You have seen these at our place - in the scrap on the other side of the river, but I didn't think to ask you about them when you've been here.  I think we have an ESCA catalogue somewhere too, so I'll check.

The maker is S.H. Johnson & Co Ltd - but not sure what country Stratford is in. I guess there are a lot of Stratfords. Can't find any company reference on the net.

 Thanks for the pics.

You know how distracted i get up there!

Yeah, I know our coffee shop is a distraction for you.

And I found out that the Stratford works of S.H. Johnson were  established in 1876 in London. (Grace's Guide) Now under the London Olympic Stadium.

I worked for S H Johnson & Co Ltd in the late fifties.  They made filter presses for many different industries.  British Sugar and I C I bought a lot of them.  Boake Roberts was a neighbour in Carpenters Road, Stratford, East London and they used the filter presses for chemical processing.  They must have sold all over the world as the ones in the top picture turned up in Australia.  

The frames were cast in the foundry which looked like a scene out of the 19th century.  They also made the filter cloths but the rubber gaskets were made by Northern Rubber in Retford.  The works backed up to the river Lea.  This is a picture of the area
