  • Patent number: 4644813
    Abstract: An improved roller door drive assembly comprising a drum, upon which a curtain is rolled, and a gear coaxially mounted to and engaged with the drum. The means of engagement consists of a plurality of forks projecting from the gear adapted to engage drum spokes. This arrangement prevents the ends of the drum while running in a swashplate manner from dragging the gear out of alignment with its driving pinion. In so doing this engagement means prevents excessive wear.
