ABSTRACT:
A cutting tool for severing a workpiece includes a main frame having a horizontal rail member and a grooved channel running its longitudinal length. There is an upright rigid head formed at one end of the frame which can either be a straight, a C-shaped or a pincerlike type of upright member. The upright head has a slot. The blade can reciprocate along the grooved channel and enter the head so that the blade can fully sever a workpiece placed in the gap between the blade and head. The cutting blade can either be V-shaped or concave shaped. The base of the cutting blade has a flange cooperating with the grooved channel for guiding the blade. The cutting blade is manipulated by a hydraulic piston which is mounted to the rear of the frame. The fluid pressure causes a shaft to extend or retract with the cutting blade attached to it. Additional features of the basic invention include handles for allowing the operator to manipulate the tool and accessories such as a portable hydraulic pump which is powered by a battery operated DC electric motor or an AC electric motor or a small gasoline driven piston engine to turn the hydraulic pump to supply hydraulic fluid under pressure to the cutting tool. There is a spreader adaptor for attachment to the tool to allow the tool to spread apart pieces of metal. There is also a clamping pliers to keep the workpiece from deforming while being cut.
