Wooden
Piston 1st Stage
Pattern Foundry Mold!
This
one of a kind
original decorative wood patterns 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 produce a
"PISTON 1ST STAGE”
.
Casting will be from Cast Iron. This pattern comes from a company with a history manufacturing
steam engines, and steam driven compressors.
Piston shape is very unique! Once casted the part will go on an engine lathe to be machined, piston ring grooves will be cut into the piston casting. Then the back of the piston will be drilled and tapped for the piston rod, then be installed on a compressor. Pistons are used on Steam Engines, Steam Driven Compressors and other drive types (Electric, Diesel, etc). Piston will compress the gas in a reciprocating manner in the cylinder.
Based on the part number this pattern dates back to 1947. Pattern is hard wood, most likely mahogany. Pattern is Approx. 9 1/4"  in diameter x 4 1/2" tall.
Total weight for this decorative industrial Post World War 11 era wood patterns is about 4 lbs.
You old 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, now Norwalk Compressor Company which opened its doors in 1864 and is still in operation today.
