ABSTRACT:
A manipulable device for projecting a horizontally-extending straight square edged light bar images upon a paper work sheet to facilitate the pasting of small adhesively-waxed printed pieces or strips to be placed upon a paper work sheet lying upon the base support of the device. The selected locations are determined and effected by relative fore and aft adjustment between a light bar projecting fixture and its base support with the work sheet thereon. Since procedure of pasting up of printed pieces upon a layout sheet can be done without the usual T-square and triangle, both hands are left free to carry out the pasting operation. Vertical guides are effected as vertical interferences of the projecting light rays and registerable upon the layout sheet along with the horizontally-extended light bar. Vertical and horizontal measuring rulers are provided upon the layout sheet base support to which reference can be made when locating the projected straight edge light bar upon the layout sheet.
