Abstract
1359436 Strain recorder TECHNOLOGY Inc 8 Aug 1972 [9 Aug 1971; 24 May 1972] 36920/72 Headings G1J and G1M A member P to be strain tested has a baseplate 15 cemented to it at end 16 only, the other end of the plate being provided with a tapered button 36 on a spring 38 to rotatably mount a dyed plastics marking disc or target 45. A plate 50 adjacent the other end of plate 15 is also cemented to the member P and supports a scriber point 55 and a pivotable cover 60 to which is fixed a plate 72 having pressed out fingers 70. In operation the target 45 is held against the scriber 55 by a spring 26 and the pivoted down cover 60 so that when relative movement takes place under stress between the plates 16 and 50 the scriber moves radially with respect to the target which is rotated or indexed by the ratcheting fingers 70 so that the strains are scratched or recorded in a zig-zag along a generally circular path.
