Abstract

287,129. Rafflenbeul, R. March 16, 1927, [Convention date]. Helical springs are constructed wit.h arcuate departures from the true helical shape in the direction of the axis. In the construction shown in Fig. 2, the spring departs from the helical shape three times in each turn alternately in opposite axial directions. Three or other odd number of departures is adopted for each turn in order that adjacent departures in adjacent coils may be opposite axially. These variations are produced in a true helical spring by introducing plugs 9, 10, 11 in suitable positions between the coils and then subjecting the spring to sufficient end pressure to distort it permanently.
