Abstract: This invention relates generally to textile carding machines and the like, and more particularly to a drive apparatus for driving a feed roll on such a machine so that a constant drive speed is provided and so the drive speed may be conveniently altered by exchanging gears of different ratios, wherein the drive apparatus includes a bracket having at least one vertical side member and a transfer shaft adjustably carried within the vertical side member. A first gear, which is driven by a drive bevel gear carried on a main input shaft, is carried on the transfer shaft, and a draft change gear is removably carried on the transfer shaft for rotation with the first gear. The draft change gear is meshed with a feed roll change gear which is carried on the feed roll drive shaft for driving the feed roll. The draft change gear and the feed roll change gear may be readily removed and replaced to alter the gear ratio of the drive apparatus and the drive speed of the feed roll with the transfer shaft being adjustable to accommodate the change of the gears.
