ROAD MEASURING WHEELS 
(Perambulators) 
A1548 to A1550 
AI548 This Perambulator or Road Measurer has been designed to provide a 
specially light, accurate and reliable apparatus. It has a detachable handle, and 
the whole fits into a light pine case, which is quite portable. The wheel has a 
heavy metal rim which is turned true, and is exactly two yards in circumference. 
It runs on ball bearings, and its semi-revolutions are recorded upon a very 
compact revolution counter, showing the number of single yards traversed by 
the wheel up to 99,999 yards. It forms the lightest and most simple and accurate 
apparatus for measuring distances on roads. 
A1549 Ditto, but improved design, with “ Sorbo ” rubber tyre. 
A1550 Ditto, as A1548, with metal rim, in metres. 
A1551 Ditto, improved design, with “Sorbo” rubber tyre, in metres.
