I forgot to mention: When my FIL was growing up the family had chickens. I think pretty much most everyone had backyard chickens in the 20's. Apparently his older brother was in charge of letting the chickens out of the coop. He rigged up an alarm clock - the old key wind type so that when it went off, the string winding around the key shaft would pull the chicken door open. You could always do that though I think I'd pull the bells off the top.![]()
There was a website showing someone making a door opener with just a clock but the mechanism looked too complicated to do something so simple. We figured we'll just keep opening/closing the door the old fashioned way with a pull string and our own arm power
