Abstract

395,331. Washers. MANFRONI, I., 2, Via Petrarca, Genoa, Italy. Oct. 8, 1931, No. 28002. Convention date, Oct. 9, 1930. Void [Published under Sect. 91 of the Acts]. [Class 89 (i).] The washer 1 is made wedge-section so that when the nut is screwed tight, it tends to incline with respect to the axis of the bolt and thus locks the threads of the bolt and the nut together.
