Don't you'll get .../wash-house winder

Hi

A schoolboy tells his teacher that one of the pupils from his class is abused by her granny. He says:

You see Ethel hev rabbits, and afore the row I

allust used to help her get their cow parsley; and I still

do, though I ain’t supposed to. While we was plucking

the parsley, Ethel say to me she ’s going to hev another

accident, she know; there ’s something her granny want

her to do and she ’on’t, and whenever she ’on’t do what

her granny want, then she hev a accident. Poured a kettle

of water over her foot last time – that was when I told

my mum. So last night Ethel and me, we took the rabbit

food round their yard, and her granny was in the washhouse.

She say to me, “You run along, Sydney Baines,

don’t you’ll get your breeches warmed. And you come

here, Ethel, and give us a hand with this mangling.” I

didn’t go straight away, I looked in the wash-house

winder and I seen Ethel’s granny take her hand and hold

it in the rollers time she give the handle a twist.

1. Don't you'll get your breeches warmed - does it mean: run and don't wet your pants?

2. Does it mean that probably through the window he looked into the room where the mangle was (I looked in the wash-house winder) and there he saw Ethel and her granny? Is seems to me that "winder" here means the same as a "mangle", but I'm not sure. A mangle in the wash-house.

Thanks
