Vintage Roller Ruler Mechanical Measuring Pencil 6" Long.
From "Three Points of the Compass" online (that does an extraordinary job of describing this piece), we quote a few excerpts:
The Roller Rule was invented by John Hoe Morehead of Clarkdale, Arizona. This combination propelling pencil and measure was used by thousands of Americans as not only a general measuring device, it also found favour when used with inch scale maps. This “measuring attachment for pencils” received U.S. Patent No. 1599780 on 14 September 1926.
The metal and plastic measure is a beauty. It is quite chunky in the hand but not as bulbous as a fountain pen. Black and gold. Measurement indicators are properly engraved and painted cream. Use of the measurer is immediately intuitive. Held normally, it is a propelling pencil, inverted and held in the same manner, it is a measuring device. Measurement of lines, be they on a map, or whatever else, is achieved by rolling the end-cap, fitted with a grippy rubber tyre around its circumference, along whatever requires measuring. The distance the wheel travels is indicated in inches along the window in the length of the pencil’s shaft. This window indicates from 0-36 in marked two inch increments with unmarked inch increments between these.
One complete rotation of the wheeled end-cap, or ‘Inch-ometer‘, measures two inches. This roller wheel end-cap has a rubber tyre fitted to stop it slipping on maps and other surfaces. Spare tyres could be purchased, costing ten cents for two.
The circumference of the cap has indications of fractions of an inch- 0, 1/4, 1/2, 3/4, 1, 1 1/4, 1 1/2, 1 3/4. There are also one eighth of an inch increments marked so it is perfectly possible to measure any scale distance up to 36 inches in one eighth of an inch graduations. And then, having reached 36 inches, simply continue measuring in the reverse direction. Perhaps unsurprisingly, I find it measures perfectl
The measures is 150mm long with a 12mm thick barrel. It weighs 27g and is comfortable in the hand, not too thin or thick and easy to grasp. The short ‘leads’ are 1.2mm in diameter and spare graphite can be stored within the propelling end of the pencil.
The Roller Rule is a lovely relic of its time and still works faultlessly, whether as a measurer, or simply as a pencil.
