Abstract
668,764. Making screws. ROLLINSON, E. W. (Eaton Manufacturing Co.). Jan. 5, 1950, No. 303/50. Class 83 (ii). [Also in Group XXV] Self-locking screws, having two threaded sections axially out of lead and connected by a resilient section, are made by machining the screw with an unthreaded section 20 and with a uniform bore 22, Fig. 2, extending through the unthreaded section and a short distance into the section 16. The walls 24 of the unthreaded section are then swaged or rolled inwards to render the section resilient and produce the required difference in the lead of the threaded sections. If greater flexibility be required flats are milled on the sections 20, prior to rolling, dividing the section into two parts. In a modification three concavities 222, Fig. 7, are pressed into the unthreaded section which is divided into three by turning a groove to remove the parts A.
