Not Betty
Beatty, as in Beatty Brothers of Fergus, Ontario; the makers of the first automatic washing machines sold in Canada. IIRC they had their start in commercial laundries.
Over the years Beatty Bros made not only washing machines, but dryers, ironers/mangles and other commercial and residental laundry appliances sold on both sides of the border. Had a table top mangle from them, that I sold on to a hospital in Hawaii.
Beatty Bros. applinaces turn up quite often on eBay, and were/are very common in the mid-west and states close to the border.
Does that answer your question?
