Abstract

946,251. Measuring. R.W.R.CHISWELL. May 30,1962 [Jan. 9,1961], No. 867/61. Heading G1M. [Also in Division G4] A measuring device comprises a graduated body member 15 having a transparent part and enclosing an elastic, graduated scale member 11. Member 11 can be extended by a ball chain 19 and is releasably held in extended position by a locking member 22 comprising a spring urged slidable body 25 and balls 33. The instrument is used to reproduce drawings to a different scale.
