Abstract

Margin stop 10 for a typewriter is positioned along a writing line to different lateral locations defined by margin rack 11 having coarsely spaced rack teeth 12. Stop 10 is releasably connected to rack 12 by either of a pair of upright wire pins 13 or 14 provided by the ends of single bent wire member 15. Ends 13 and 14 are spaced a distance 16 equal to a multiple of the spacing between teeth 12 plus one half the spacing between teeth 12 such that only one end 13 or 14 can be in engagement with the teeth 12 at any one time. Stop 10 is relocated by depressing slider 17 rearwardly to lift ends 13 and 14 from rack 12. After stop 10 is repositioned, slider 17 is released to draw ends 13 and 14 forwardly such that one or the other falls into a space between adjacent teeth 12.

Fine Pitch Margin Stop

Margin stop 10 for a typewriter is positioned along a writing line to different lateral locations defined by margin rack 11 having coarsely spaced rack teeth 12. Stop 10 is releasably connected to rack 12 by either of a pair of upright wire pins 13 or 14 provided by the ends of single bent wire member 15. Ends 13 and 14 are spaced a distance 16 equal to a multiple of the spacing between teeth 12 plus one half the spacing between teeth 12 such that only one end 13 or 14 can be in engagement with the teeth 12 at any one time. Stop 10 is relocated by depressing slider 17 rearwardly to lift ends 13 and 14 from rack 12. After stop 10 is repositioned, slider 17 is released to draw ends 13 and 14 forwardly such that one or the other falls into a space between adjacent teeth 12. Thus, stop 10 can be placed in different locations spaced at intervals equal to one half the spacing of teeth 12.
