This from Drew Smith:
In various comments by Bill Post, Phil Stenholm, and others the term “inhalator” is used. The original inhalators were beasts and heavy. Here are a few pictures as well as a newspaper article about Prospect Heights FD’s first E&J Resuscitator-Inhalator. The PHFD currently has two of these although neither is in-service. As indicated in the article, the first unit was acquired in 1948. A second unit was acquired sometime later. The black and white photo with the E&J is from sometime in the 1960s. In a wooden case, with two steel D cylinders and the large brass chrome-plated “guts” this thing is easily close to weighing 50 pounds.
