ABSTRACT:
Adjustable handles for road surface cutting saws are disclosed. The handles are elongated tubular members projecting rearwardly from opposite side edge sections of a generally vertically disposed housing. The handles are independently adjustable, forwardly and rearwardly in the longitudinal direction and angularly about a transverse horizontal axis, to position hand grips on the handles in optimum position for operator control of the saw, operator access to the saw controls and storage of the handles in a forwardmost position to enable the saw to be stored in a compact condition. A pair of substantially identical clamp assemblies including inner and outer clamp elements are mounted on the inside of the side walls adjacent the rear of the housing and clampingly hold the handles in the selected longitudinal and angular positions. A bolt extending substantially transversely through the inner and outer clamp element of each clamp assembly and the side wall cooperates with a knob on the outside of the side wall to tighten or loosen the clamp elements.
