 Wooden PISTON 4th STAGE Pattern Foundry Mold 

This one of a kind original decorative wood pattern was hand crafted by expert industrial craftsmen of yesteryear. The pattern maker was the “artist” of the industry. First was the dream, then the drawing (blue print), then the wood pattern, then the metal casting to be machined to the finished product. The wood pattern had to be made to strict tolerances else the finished product would be off thus scrapped. This is what makes these patterns so beautiful; they were made to precision the old fashioned timely way! They were not massed produced but one of a kind!  

This pattern was used in the foundry process to help produce a  PISTON 4th stage.  Once casted, the Cast Iron piston will go on an Engine Lathe to be machine with grooves for piston rings. A hole will be drilled in the center for the piston rod to go through. This is what we call a "steeple" as other piston will also be "stacked" onto the rod 1st - 4th stage). This pattern come from a company with a history manufacturing steam engines, and steam driven compressors.

These patterns are used on Steam Engines, Steam Driven Compressors and other drive types (Electric, Diesel, etc). This  core box was used as part of the piston casting. 

The beautiful Pattern is hard wood, most likely mahogany. This pattern is Approx. 14 1/4" in Diameter x  8 3/4" high

Total weight for this decorative Industrial era wood pattern is about 15 lbs. 

Pattern makers or wood workers will really appreciate these pieces. Perhaps you have a fancy for steam driven equipment of yester year. In fact anyone interested in American Industrial History will enjoy this one of a kind souvenir from the past.

 In addition to this pattern mold you will receive a four page history of the Norwalk Iron Works, which opened its doors in 1864.
