Cliff Peterson, a civil engineer who collects patent models,
made the buy of his life when he bought more then 40,000 of them
for half a million dollars in 1979.

Now he’s opening the more than 800 crates they came in and
putting prices on them. Some of the models deal with steam
inventions.

Here are samples of drawings and papers from a package Cliff
sent IMA:

Steam engine valve gear, by P. W. Gates, D. R. Fraser and Thomas
Chalmers, all of Chicago, patented July 5, 1859’a new and
improved valve cut-off gear.’

Improvement for feeding boiler in locomotive, marine and
stationary steam engines, by William H. Hubbell and David Matthew,
Philadelphia, PA, patented May 29, 1855.

Means for taking the side strain from the rotative shaft and

Kentucky, September 18, 1866.
