Not the simple chain, like used for pulling a log. I’m talking about the type of chain used w/sprockets, like the modern bicycle chain or timing chain used in a car? [Untitled] A Brief History of Chain The Complete Guide to Chain: A Brief History of Chain …

Without looking yet, I’m going to guess the Dodge boys. Well OK, I was a little off. I don’t remember what class it was in but we talked about all the the early designs of engines and so on that simply could not be produced without more modern machine tools. The ideas were all there but they just…

Yep, it’s the Scientists who get all the fame and glory but it’s the hundreds of nameless Engineers who actually turn it into reality.

Looks like typical gm engineering drawings.

[image] LoudThunder: This 1943 Mack FCSW mining dump truck used Chain Drive… Up until… maybe… 10 years ago, I used to see a couple of really old Mack chain-drive trucks at a supplier of gravel, stone, and mulch. So far, I haven’t been able to find any photos of comparable ones for confirmat…

[image] VDCdriver: I don’t think that they could have been any newer than the '30s. I may be wrong but I think they were still had chain drive up till the late 40s and early 50s.

As a kid, one of our neighbors had a house moving business and he would park his equipment behind his house. I don’t know what year the big Mack was, maybe 40’s, but I distinctly remember the chain drive. Big heavy chain, like on farm equipment.

For more on this topic, Google will show you an interesting u-tube how bicycle chains are manufactured. Not as simple a design as you might think. For example there’s two kinds of the side links, inner & outer, and they are made different ways. The inner links have to be more robust b/c they c…

I put a million miles on my bike and had the original chain. My cassette was wasted but chain seemed ok. Tech said it was an illusion. So I replaced both. Actually I changed 1 front sprocket too.

[image] Cavell: So I replaced both (the chain and the cogs). The old chain may look ok, but it stretches with use, so the pitch change means it won’t mate up correctly with the new cogs. An old chain will usually skip with new cogs. Ask me how I know! … lol … I’ve had to replace chains and…

Guess who invented the roller-bearing chain?

Google “chain driven trucks” and then Click on Images. I’m sure your memory will be refreshed. That is what I did and I was surprised that the photo of the '43 Mack came up and after I Clicked on it, I Clicked on “Visit” and Goggle linked me to the source. I originally thought chain driven vehicles never made it past '35 or so and that the rear end “pumpkin” with Differential and Planetary gears kind of took the world by storm…
