These boats had what was referred to as roller reefing, in which the mainsail was reefed by wrapping the foot of the sail around the boom. As you note there was a rod which connected the casting on the boom to the slide on the mast. The parts were machined so that the boom could rotate when the boom is pulled aft from the mast and then would lock in place at that point of rotation when the spring pulled the boom back towards the slide. Typically the lock would engage at four points; 0, 90, 180, and 270 degrees of rotation.
