Riveting gangs worked in well-organized teams, like acrobats in the circus. The man known as the heater (or passer) heated the rivets in a forge, then tossed them to the upper floor. There the rivets were scooped out of the air by the catcher, who used a tin bucket. The bucker-up jammed the red-hot rivet into a hole in the steel and held it there while the riveter, or gun-man, drove the bolt home with a pneumatic gun. The rivets were carried to the gang by bolt boys, many of whom dreamed one day of joining the team.
