Anesthesia tank

Anesthesia tank

Large round gasometer, or tank, used to hold nitrous oxide anesthesia (a) is painted black with very elaborate hand-painted floral designs in gold, green and brown. A large chrome valve and nozzle are at base of tank. Tank lid (b) is also black with floral designs. Lower part of lid is galvanized tin and extends 17" down into tank. Tank sits on black cast iron base (c) with elaborate, decorative scrollwork around the bottom. Base is a pedestal which divides into two arms. Top ring of base is bolted to arms of pedestal. On top of tank is an elaborate chrome bracket (c) attached with rods to the sides of the tank. The bracket supports a chrome rod (e), which was once attached to the center of the tank lid. A hook on the bracket's side possibly held a hose. Lid of tank is designed to slide up as the tank fills with gas providing constant pressure. The bracket on top would support the lid as it slides. Inside the tank is a galvanized tin pipe one inch diameter (f), a cone attachment (g), a .75" diameter pipe (h), and a 1.25" diameter for it (i). Pipes inside allow gas to be drawn off the top.

Gasometer was used by Dr. John Vincent Cole in Marysville, Montana.
