I think what look like wheels are actually the base that would have been concreted into the ground. As S4 said it would have had a bearing at the top. That would probably have carried the paddle arms to mix pug with dirt, etc. for Brick making.

Many years ago there was something similar at the north end of Cryalls Lane and also near Chilton Playing Field, Sittingbourne. Both were partially submerged in water and `alive` with newts. When I was about 9/10 we spent some time watching the newts darting about. We called these machines `Mixers` and assumed they were used in the brickmaking industry. If I remember correctly there a number of these `mixers` in the St. Michaels Road area and undoubtedly used in brickmaking..

Could be the base of a crane, a hand worked one at that. However I do have a slight issue with the fact the pole is tapered, there is a bearing area at the top but I'd need to see more before being certain. I doubt if it is the base for a waggon turn-table as they tend to have a narrow base (just a big peg really) and are not load bearing as the wheels around the circumference take the weight. There is a crane listed on the map, could be the base of that.

The 1897 map shows that there was a railway goods yard with wagon t.tables and a crane roughly on a line between the modern St. Michaels Road and the railway. Could our mystery item be a spigot for one of these t.tables or the crane?.

Are they wheels? There are no spokes and the lower one seems to be the other half to the top one. I got the impression it might be the base of something.

It could be part of a puddling or pugmill but the wheels look a bit thin

It looks like part of a clay puddling machine.  The size seems about right to me.   Or, I could be completely wrong.  Still, an interesting find.

This large lump of Machinery was dug up along St Michaels Road by Regeneration Scheme Contractors.
The road was built over the old Brickfields to the North of the Railway back in the mid 1960's.
Can any of the you recognise what piece of Brickfield equipment it belonged to. I used to play on the site in the 1950.s and don't recollect seeing anything like it.
