A line marking device (10) includes an elongated body (15) which mounts a marking filament (20) that is loaded with marking powder (55). When the filament (20) is snapped against a surface, a portion of the powder (55) is deposited on that surface along a well defined line. The body (15) also mounts a protractor (30) and spirit levels (22, 23) that are used to locate or set the device (10) in a predetermined position prior to snapping the marking filament (20) against the surface to be marked. 'The marking filament (20) extends through a shuttle chamber (53) that contains a supply of marking powder (55). That shuttle (50) is moved back and forth on the body (15) to recharge the marking filament (20) with the marking powder (55). In a second embodiment of this invention the marking filament (20) is pressed rather than snapped against the surface to be marked.

Un dispositif (10) pour marquer une ligne comporte un corps allongé (15) qui porte un filament marqueur (20) qui est chargé d'une poudre de marquage (55). Quand le filament (20) vient frapper contre une surface, une partie de la poudre (55) est déposée sur cette surface le long d'une ligne bien définie. Le corps (15) porte également un équerre (30) et des niveaux à alcool (22, 23) qui sont utilisés pour localiser ou immobiliser le dispositif (10) dans une position prédéterminée avant que le filament (20) ne vienne heurter la surface pour la marquer. Le filament de marquage (20) traverse une chambre (53) à navette qui contient une source de poudre de marquage (55). La navette (50) fait un mouvement de va-et-vient sur le corps (15) pour recharger le filament marqueur (20) avec la poudre de marquage (55). Dans une seconde forme d'exécution de cette invention, le filament marqueur (20) est pressé contre la surface à marquer au lieu de la heurter.
