Abstract
A writing guide for writing letters and words in a transverse line on a sheet mounted on the flat surface of a baseboard, includes a rectangular frame movable along a detent rod carried by the baseboard. The frame is rotatable around the rod to enable the sheet to be placed on and removed from the baseboard. The frame has two rigid spaced rails joined by rigid end plates. A flexible string has two laterally movable sections disposed between and parallel to the rails to define a space for writing transversely along the sheet. The string may be connected in electric circuit with an electrically operable sounding device, power supply, and metal tip of a writing implement, to sound an alarm when the tip of the writing implement contacts one of the string sections.
Claims9
A writing guide, comprising:
- a rectangular, flat frame having coplanar, parallel upper and lower rails joined by end plates, and adapted to overlay a sheet on a baseboard;
- a string means carried by said end plates and having two spaced string sections disposed between and parallel to said rails to define a space for writing a line on said sheet, said string means being flexible to yield laterally when contacted by a tip of a writing implement, to permit completion of a symbol being written on said sheet;
- a flat block disposed adjacent one of said end plates and coplanar therewith;
- attachment means engaging ends of said string sections with said block;
- guide means extending between said flat block and said one end plate to hold said block in sliding engagement with respect to said frame;
- and
- spring means extending between said flat block and said one end plate to permit said block to slide laterally against spring bias when either one of said string sections is flexed laterally.
