Abstract

651,151. Bolting. ERICSSON TELEPHONES, Ltd., and WILMAN, C. W. May 14, 1948, No. 13271. [Class 89(i)] [Also in Groups XIII, XXIV, XXXII and XXXVII] In a device for magnifica tion of a relative movement produced by the differentia: thermal expansion of a rigid frame and a series of bowed leaf springs mounted therein (see Group XIII) the leai springs are supported at each end by a screw 3 split to embrace the frame 1 and adjustably secured thereto by two nuts 9 (one only being shown in Fig. 2) which engage with slots 11 on either side of the frame member. Packing pieces may be inserted in the split ends of the screws to prevent closing.
