Abstract

367,750. Washers. DARDELET, H. L., 5, Rue Menou, Nantes, Loire Inferieure, France. Aug. 19, 1930, No. 24825. Convention date, Aug. 19, 1929. Void [Published under Sect. 91 of the Acts]. [Class 89 (i).] To reduce the shear stress on bolts 4 securing members 3, 2, concentric grooves 2a, 3a are cut around the bolt holes and form a housing for a washer 1 having concentric ribs engaging the grooves. The washer may be of conical form initially, and of such thickness that the plates 2, 3 are not in contact. A cutter 6 for shaping the grooves may be combined with the bolt hole drill 8, Fig. 6, or may take the form of a blade 12 secured in a guiding- bar 5 by a set screw 14.
