Open the CIPO recordAbstract From the Canadian patent
A visual marker for indicating or identifying rolled drawings provides a marker member in the form of a flat disc with a boss on a rear surface of the disc. A wire loop has ends turned inwardly for receipt as a press-fit in a slot defined in the boss. The ends define an axis which can rotate within the slot so that a front face of the disc can either be positioned at right angles to the plane of the loop for presenting axially from the end of the rolled drawing or substantially in the plane of the loop for facing upwardly when the loop is positioned horizontally between planar sheet or for example, a stack of paper.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
