ABSTRACT:
A hand operated tubing cutter adapted to apply a selectable force to tubing to be cut, with the cutter having an elongate, substantially "C" shaped body member and defining a recess for receiving a piece of tubing to be cut. A spaced pair of rollers is operatively mounted in the central recess, directly against which rollers a piece of tubing to be cut is to be placed. An elongate cavity is disposed in the body member in substantial alignment with the pair of rollers, and an elongate ram member is slidably disposed in a non-rotatable manner in the elongate cavity, one end of which ram member supports a cutter wheel. The cutter wheel is rotatably supported in an opposed relationship to the rollers, and a rotatable adjustment device is located on the body member at a location comparatively remote form the rollers. A compression spring is disposed in the body member and operably interconnected with the ram member. The rotatable adjustment device is selectively rotatable to control the positioning of the ram member and therefore the positioning of the cutter wheel with respect to the rollers. The selective rotation of the rotatable adjustment device also modifies the force applied to the ram member by the spring, and therefore the force applied to the cutter wheel, thereby selectively controlling the amount of force consistently applied by the cutter wheel during the cutting of tubing residing on the rollers.
