Very little is known about this most unusual and delightful little hand-powered shaper except that it was probably made circa 1900 to 1920 and bears a close resemblance to another model marked "Polygon".
With a conventional elevating knee on one side, the base, was formed into a large socket at the back to accept the swivelling-head unit. At each side of the main cylindrical boss were elevating "V" pads, the function of which is unclear. The ram travel was 6" and the side movement of the head, which carried an automatic ratchet feed, a remarkable 10".
One interesting point about the Bradley was the availability of a separate head for cutting internal keyways that interchanged with the standard clapper box..
