This is an 1850 Ashcroft USA Gauge, Blower Lub. Oil, bronze tube Duragauge. The Ashcroft MFG. Co. dates back to 1852 when Edward H. Ashcroft bought the rights to a French pressure gauge design to revolutionize the pressure gauges for steam engines. The invention of a pressure gauge that could monitor high pressure decreased the amount of steam engine accidents.
The gauge is made off bronze and cast iron. The dial face reads: Blower Lub. Oil – 1/4 Lb. Subd. – Duraguage – 1850 Ashcroft U.S.A. – Patent Dates Inside – Bronze Tube Duragauge. The Bronze ring around the front is 6 1/4 in diameter. The glass on the top of the dial has a few nicks and measures about 4 inches wide. The back of main housing measures about 4 1/2 inches wide. From the face to back it measures 2 1/4 inches with the connector it is 3 3/4 inches. When mounted to the wall, this pressure gauge will extend out from the mounting surface by about 3/4 inches. The connection point for the source being measured is bronze and measures 1 1/2 inches. It weights 4.8 Pounds and reads up to 30.
This is a very versatile item. It will be of interest for a broad range of designers – Steam Punk to nautical design in mind.
