The 1930’s era gas-powered compressor in this photo was made by Schramm Inc., a century-old Pennsylvania company that is still in existence. In the old days Schramm made compressors; it now specializes in truck- and trailer-mounted drilling equipment for wells, geothermal, and energy exploration. The compressor shown here would have originally been up off the ground on iron wheels; the piece sticking out the front is the hand crank for starting the engine.

This was produced by the Power Machinery Company of Vancouver, BC and was first sold in 1949. Of course chainsaws have been around for longer than that. The first portable gas-powered model was built by Festo (the original owner of Festool) in 1925.

What you want to look at here are the two wooden frames with fuel tanks and motors attached; the one in front is labeled RM Wade &amp; Company. These are drag saws, which came after the hand-operated cross-cut saw but before the chainsaw. They consist of a two-stroke engine attached to a cross-cut saw blade. The one in back has a blade on it; the one in front does not. The blade on a drag saw could be oriented to fell standing trees or cut downed trees into shorter pieces. It’s a clever design, and as hard as it must have been to haul these things into the forest, it had to have been much easier than sawing by hand. To see one in action, search for “drag saw” on YouTube or <a href="http://www.youtube.com/watch?v=3WREE3xF2ko" xmlns="http://www.w3.org/1999/xhtml">click the link to this video</a>.
