Here in Cheshire it's a clothes horse, but DGM was from Lancashire and always called it a maiden!
We had a pulley which raised and lowered just in front of the black leaded range in the parlour. In the days before we had a washing machine of any sort, washing would be done in the 'dolly tub' in the scullery, put through the mangle (which got it drier than any modern spin dryer can) then dried on the line in summer, or the pulley in winter. The clothes horse or maiden was only ever used in our house to 'air' clothes, never actually to dry them.
