Abstract
A tab rack bar and tab stops are disclosed which provide for the ability to set a first set of tab stops on one side of the tab rack by displacing the tab stops into the path of the tabulator mechanism and then by rotating the tab rack set a second set of tab stops completely independent of the first set of tab stops by likewise displacing the tab stop into the path of the tabulator mechanism. The double tab rack and tab stops provides the capability of presetting and then selecting a first set of tab stops such as may be used for letter type correspondence and a second set of tab stops which may be used for columnar layout or statistical report typing, without having to clear and then reset the desired tab stops each time you care to switch.
