Abstract
1377607 Testing timber MEASURING & PROCESS CONTROL Ltd 26 Nov 1971 [27 Nov 1970] 56534/70 Heading G1S A length of timber 1 is tested by applying equal bending couples at two points along its length, changing the magnitude or direction of the couples, and measuring the change of curvature so produced along the length of the timber. The couples may be applied by abutments 9, 10 and load applying rams 13 or by pivoted jaws Fig. 2 (not shown). The change in shape of the timber as the couples are reversed Fig. 5 (not shown) or increased Fig. 4 (not shown) is measured by a series of feelers 15 and sensors 14. The sensors 14 may include linear transducers or strain gauges and their outputs may be fed to a computer programmed to recognize possible patterns of curvature and arranged to effect marking or grading of the timber. The abutments 9, 10 and rams 13 may be movable by power operated means and preferably are automatically positioned according to the length of timber. In the arrangement of Fig. 7 for longer pieces of timber, the right hand end is tested at a first station 17, the middle at a second station 18, and the left hand end at a third station 19.
