Wooden
2nd Stage Cylinder
Pattern FoundryMold
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
"2nd Stage Cylinder”
.
Casting will be from Ductile Iron. Theses patterns come from a company with a history manufacturing
steam engines, and steam driven compressors.
Cylinder is very unique! Once casted the part will go on a VTL for boring and machining then, then on an HBM to have the valve pockets machined out, then drilled and tapped then be installed on a multistage compressor. "60-40-18 is the material
designation which means the cylinder will be casted using ductile Iron. "HP" Means "High Pressure"
Cylinders are used on Steam Engines, Steam Driven Compressors and other drive types (Electric, Diesel, etc). Cylinder will house the piston to compress the gas in a reciprocating manner in the cylinder.
Based on the part number this pattern dates back to 1946. Pattern is hard wood, most likely mahogany. Pattern is Approx. 25"” Long x  17" in dia.
Total weight for this decorative post World War II era wood patterns is about 45 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.
