Abstract
617,076. Temperature-responsive actuating elements. WIGAN, E. R. Dec. 4, 1945, No. 32770. [Class 64(ii)] [Also in Groups XX, XXXII and XXXVII] A spring assemblage comprises a bimetallic or other spring member resilient in a direction transverse to its length, two anchorages spaced apart and rotatably adjustable about parallel axes, means for fixing the anchorages in their adjusted angular positions, at least one of the anchorages being arranged to permit adjustment of the spring transversely to the axis of rotation of the anchorage and means for clamping the spring in the latter adjusted position. In the construction shown in Fig. 1, a blade spring 1 of length l, is adjustably secured in anchorages 2, 2<1>, the distance apart x, of which, and the angular setting of which about an axis perpendicular to the plane of the mounting plate 4, are adjustable to control the behaviour of the spring under loads applied thereto, such as at 6. By suitable adjustment of the ratio l/x and/or the couples applied by the anchorages the stiffness of the spring under such loads may be reduced to zero or made negative to produce a snap-action spring. In the latter case the spring may be of bi-metallic form so that a snap-action occurs at a particular temperature. A spring of known negative stiffness may be coupled to an unknown spring of positive stiffness to effect calibration of the latter. In the construction shown in Fig. 3 the invention is applied to give parallel motion to a carriage 7 which is constrained to move rectilinearly along an axis xx due to its suspension by the springs 9, 9<1>, under the action of a lead screw 8. In Fig. 5 the carriage 7 is suspended by a single pair of springs 9. In Fig. 6 (not shown) the two springs of the construction shown in Fig. 3 are each of semi-circular shape and are combined at mutual anchorage points to form a single spring of oval shape, which when unstrained is circular. Other applications are to vehicle springs and to relay armatures.
