Item — Box: PCA0097-1
Identifier: PCA0097-1-6
Scope and Contents
A roll crusher dismantled for repair. (Howard Hayes is the man on the left). The mechanics on the maintenance crew were putting a shell on one of a set of two rolls. The circular device made of pipes was an oil or gas burner used to heat the shell. The shell was like a thick steel tire. It fitted over a very heavy split rim that was keyed to the axle. The men were tightening the split rim while the shell was hot. When the shell cooled it shrank to make a very secure fit.
