I have one of the old cast iron differential style chain hoists made by "D. Round & Sons Makers - Cleveland O. U.S.A." that had belonged to my grandfather. It's old but doesn't appear to be very worn so I'd like to put it back to light duty work (sentiment and all). At some point someone cut the chain off of it and I don't have a sample of what it had.
The differential sprockets have cast grooves and ledges on them for the chain to lock into, but they are not mirror representations of the chain. The dimensions I measured ended up being a non-existent size of chain, so I went for something we had on the rack and it seemed to fit ok and worked with no load.... until it got under a slight load the chain would slip in the sprockets, so obviously it's not the right size chain.
Before I start buying random chains, is there any way to measure a link chain sprocket to determine what size it takes?
My research turns up lots of stuff for roller chain, but nothing on link chain. I did find that the company is still in business making industrial lifts and hoists, so I shot them an email, but I imagine this is small potatoes for them.

I did find a picture of another of the same hoist, so worst case I can take the calipers to the computer screen and do some math.....
