When is a rule not a rule? When it’s four rules!
This deceptively simple rolling ruler offers an unexpected “twist” on the conventional design. Made of what appears to be turned rosewood, only subtle differences in the grain of the wood betray its secret: each section unscrews to reveal different sized compartments within, turning a basic desk accessory into a portable writing set.
The largest compartment is long enough for pencils or quills, while two smaller ones might have been used to hold nibs or even a small ink bottle, judging by the profiled interior partition. The only distinguishing feature on its outer surface is the inscription “H. H. DALTON. PATENT” around a crown symbol at one end of the rule.
I have not yet managed to trace the patent referred to, so any information would be welcome. What the photos cannot convey is the ridiculous level of craftsmanship required to make the parts fit together so perfectly, without which it would be absolutely useless as a ruler. I have seen many other so-called rulers that double as pencil cases, but Dalton’s is the Fabergé egg to their Kinder Surprise.
