Abstract

729,628. Scaling-tools. ATKINSON, A. E. Sept. 18, 1953, No. 25843/53. Class 99 (2). [Also in Group XXI] Each spring finger 8 of a scaling-tool comprises a closely-coiled helix 12 of spring wire and one or more deformable inserts 13, 14, 15 positioned within the helix. The shape of the finger is determined by the shape to which each insert is deformed when within the helix, and the resilience of the finger is due to those portions of the helix in which there is no insert. The finger may be U-shaped. Specifications 668,350 and 701,540, [both in Group XXI], are referred to.
