Abstract
A measuring rule including a numerical counter with a tapered knurled shaft mounted for rotation, a rotating spool having an elongated cord wound around it and spring bias means for rewinding the cord around the spool. Stop means are provided for automatically preventing rewinding of the cord about the spool until the stop means is disengaged by the user of the rule, while permitting the cord to be freely pulled off the spool. The cord passes from the spool around the knurled shaft to turn it and the counter as the cord is pulled off the spool, through the stop means and out of the housing so that the length of cord pulled out of the rule and passing around the knurled shaft is indicated by the numerical counter. Error correcting means are further provided for adjusting the location where the cord passes around the tapered shaft along its length.
