Hill Climbers & Oddities at the Wheels Through Time museum
In addition to the nifty bikes and cars on display at the Wheels Through Time Museum, there are some odd contraptions too. This is a reciprocating ice saw, powered by a 1915 HD motorcycle. The large straight saw blade slices forward and back. Think of it as a piston… (ignore the round blade on the wall, that is a different display). The motor & gearbox spins a big rear wheel sprocket, but there is no rear wheel attached to it. Instead that rear axle works as a crankshaft. The crank is shown pointing downwards in the photo. Attached to it is a long connecting rod, slanting upwards about three feet to the back end of the saw blade. The blade runs to and fro on some linear supports which go all the way back to the rear axle. And the whole setup is mounted on what looks like an old frame rail from a pre WWII car. A motorcycle rear wheel and a a wheel from a cart allow the user to move the car frame and thus the whole apparatus into position over the ice. Keep the children and the dogs out of the way when running this thing! click the pic for a larger photo.
A little airplane, powered by an early V twin motor. IOE type inlet valves can just be seen.
