ABSTRACT:
A carpet scribing device and gauge for measuring the size of a carpet module adjoining a baseboard. The device comprises a rod on which is slidably mounted a block encased in a bracket having a dependent portion which abuts against the edge of laid carpeting. The end of the rod which abuts against the floor board is provided with a needle extending angularly downwardly with its point in vertical alignment with said end of the rod. By reversal of the block on the rod, the device is useful for carpeting stairs.
