The Lady Wearing A Black Lace Blouse
Wearing glasses is using an extractor, which where very common in laundromats and indeed commercial laundries as well.
Because early washing machines of all types (aside from perhaps Frigidaires) had such low final spin speeds, laundry would emerge quite wet. Heavy and sturdy items like towels, jeans, some linens,blankets, and such would be taken from the washing machine and put into the extractor to spin out more water, thus less time would be required for drying either in a tumble dryer or on the lines. Bock is a common name today for commercial extractors.
While also common for home use in the UK and Europe, extractors weren't really a huge sell for home use in the United States.
As for commercial use, even today some laundries still send heavy items from washing machines through an extractor because their washing machines have low final spin speeds. Or, they are still using old machines that are mainly "washers" and laundry is moved to "extractors" to be spun. If one looks at commercial laundry catalogs you'll see machines that wash and spin still described as "washers & extractors".
Due to liability issues extractors are mostly gone from laundromats. Last time one saw one was a laundromat in Brooklyn near Fort Greene.
