Re: 1869 Roper caloric engine info & engraving
There are at least two versions of the Roper engine shown in early Scientific American Magazine online at Cornell's "Making of America" site. One of these is quite spindly and frail looking much like the HF Museum entity. The other is a bit later model and appears more robust.
Someone out there in cyberland has reproduced the Roper engine and ran it for a short video? I haven't seen this for a while but I expect someone knows the link? Joe K

Re: 1869 Roper caloric engine info & engraving
Hi joe and j..
There was a guy named Olaf Bergie who made copies of several air engines and one was a roper. Oly passed awa but I think his son is possibly showing the engines at lake itaska show. He also made a big ericsson engine It's been a while but check on the buckett and trewella engine too. I think they are similar design. he's a link to some pics of the roper
