Abstract
A support for an idler gear is pivotally mounted about the driving gear axis in a gear driven platen drive for a typewriter. A constraining member mounted with the interchangeable platen engages and constrains the support in a position to insure engagement of the idler with the platen gear and may be sized or shaped to insure proper positioning of the support and idler for a number of different platen gears of varying diameters, allowing platens and platen gears to be readily changed to vary the line feed increment as desired by the operator.
