Abstract
152,885. Goodman, R. J. Dec. 2, 1919. Wood-screws. - A selfcountersinking screw has one or more V-shaped notches 2 in the head, the edges of the notches being of different lengths and tangential to circles of different diameters concentric with the head of the screw. Inclined or curved grooves 4 run from the notches down the stem of the screw to the thread. Reference has been directed by the Comptroller to Specifications 11387/05, 24725/12, and 140,983.
