Electrically heated soldering tool having work gripping jaws

In an electric heat gun, the combination of a case, said case including a pistol-grip handle portion adapted to be held in a person's hand, an upper stationary jaw secured to said case and extending forwardly from a front end thereof, a pivotable lower jaw pivotable toward and away from said upper jaw, said lower jaw being pivotable about a transverse pin supported laterally in said case, said lower jaw extending forwardly from the front end of said case, and arranged in juxtaposed relation to the upper jaw for clamping an object therebetween, a trigger-like lever protruding from said case, and being positioned relative to said handle, for being squeezed by an operator's finger while holding said handle, said trigger-like lever being connected to said pivotable lower jaw for pivoting said pivotable jaw about said pin, heating means associated with each of said jaws for heating said jaws, and means associated with said case for energizing said heating means, said heating means comprising an electric heating element within an interior of each of said jaws, said means for energizing said heating elements comprising an electric circuit extending into an interior of said case, said electric circuit including an on-off switch and an indicator lamp supported by said case, an electric extension cord extending outwardly of said case, and an outer end of said extension cord having a male plug for connection to a household electric socket, and the confronting portions of each said jaws being approximately semi-cylindrical in shape, so that, together, they can grasp around a cylindrical pipe when the pivotable jaw is moved toward the stationary jaw by said lever for heating said pipe;

• each of said jaws being interchangeably removable from said case, each of said jaws having a pair of jack-like prongs and adapted to be inserted into a jack-like socket, said prongs being electrically connected to said heating element in said jaw and said jack-like socket forming a part of said electric circuit, one of said jack-like sockets being integral with said case, and the other of said jack-like sockets being carried on an arm that is integral with the free end of said trigger-like lever pivotable about said transverse pin;
• said electric heat gun additionally including a separately controlled forced air draft system that includes a motor-driven fan associated with said case and operated by a manually triggered switch button, an air duct extending from said fan into each of said jaws, and a plurality of radially extending openings on the confronting portion of each jaw and communicating with said air duct for directing air against a surface of a work held by said jaws.
