Abstract
A spring end cap for use in rotatably driving a glass conveyor roll of ceramic is disclosed as incorporating helical spring coils that clamp onto an end of the roll. Each spring coil has a diameter in an undeflected condition slightly less than the diameter of the roll end so that coil deflection increasing the coil diameter allows the coils to receive the roll end prior to being released in order to clamp over a round outer surface of the end. Different embodiments of the end cap are utilized with frictionally driven rolls as well as with toothed sprocket or gear driven rolls. Ease of installation is achieved when the spring coils are all part of a single helical spring. The end cap can also be utilized to repair a broken roll end and then must include at least three helical springs whose coils are axially threaded so as to provide circumferentially spaced clamping that secures the broken roll end to the rest of the roll at the fracture.
