Abstract

840,493. Helical springs. BOSCH G.m.b.H., R. April 10, 1958 [April 11, 1957], No. 11375/58. Class 108(3). Spring 6, Fig. 2, has a last convolution 9 the outer diameter of which is smaller than the inner diameter of convolution 10. Thus, when the spring is compressed the last two convolutions do not come into contact with each other. A U-shaped plate 14, Fig. 3, slides into groove 16 and supports convolution 13 of spring 12. Convolution 13 is a tight fit between rod 17 and edges 18 formed on both sides of slot 15. In a further embodiment a convolution 22, Fig. 4, has the full pitch of the other convolutions and a convolution 20 only occupies three quarters of a turn. The end convolutions could have a greater diameter than the rest of the convolutions rather than a smaller diameter.
