Abstract
A plurality of adjacent open-ended flat timing belts each has parallel spaced teeth, and opposite end portions of each belt are connected to a shuttle or carriage platform by corresponding relatively adjustable clamping blocks and plates having teeth engaging the teeth on the belts. The belts extend around a common drive sprocket having engaging teeth and formed as part of a drive shaft connected to a multiple speed drive having reversible electric motors and oil-shear clutch and brake discs. The belts also extend around a tail shaft having corresponding tail sprockets with teeth, and adjacent tail sprockets are free to rotate relative to each other. One of the clamping blocks for each belt is adjusted relative to the platform and the other clamping block for the belt to obtain the same tension in all belts so that each belt may be operated at its full rated capacity.
