Actually It's Newer Than That!
Electro-Hygiene had its beginnings in March of 1934 as a wholly owned subsidiary of the P.A.Geier Co. On August 8, 1941 Electro-Hygiene became a company in its own standing when Arthur R. Frankenfeld, F.J. Gottron, and James Farrell filed for incorporation, and P.A. Geier continued to build their vacuums for them until they went out of business in 1983. Arthur Frankenfeld was still the president of Electro-Hygiene when I was selling them in 1974, and I had the privelege of meeting him at a sales convention at the home office in Dayton, OH.
The first model of Electro-Hygiene was the model 80, which had a smooth, polished surface and an inline switch on the cord. It was built from March of 1934 until the late 30's, when the model 94 was introduced, which was produced until they switched over for war production in 1942. The 94 had a hammered finish (not hammertone, but an actual hammered finish), and a switch on the handle, with the cord having a pigtail connection at the bottom of the handle so it could be broken down for use as a hand vac. Both the model 80 and the 94 had a black bag with Electro in red and Hygiene in gold running horizontally across the bag.
After the war, the model 230 was produced, still a straight suction machine, from 1945 until 1954, and during the last year of production a slightly modified version, the 2-230, was produced. With the 230 they went back to the smooth polished finish, redesigned the bag, with Electro running horizontally and Hygiene running vertically down the bag, first black with red & gold printing then later blue with red & gold printing.
The reason Electro-Hygiene remained a straight suction machine long after Royal began producing vacs with a revolving brush was that they didn't know what to do about the crystal chamber, which was such an important part of the Electro-Hygiene that they refused to market a machine without it. A chamber was designed that would snap on the front in place of the adjust-o-rite cover, and the first revolving brush Electro-Hygiene, the model 285, was introduced in 1955. Now for some pics. First, the model 80,all original except the bag and the cord.
