Soldering gun having finger actuated feed unit apparatus

A soldering gun apparatus for feeding a solder wire to work, comprising

• a barrel member for passing solder wire therethrough and a depending handle portion for manipulation of the gun, a guide means for guiding of the wire from said barrel member, a feed wheel adapted to engage the wire and feed the wire through said barrel member and into said guide means, trigger means in said handle for rotating said feed wheel, a pressure wheel rotatably secured within said barrel in alignment with said feed wheel and including a pivotal support lever and a resilient means pivoting the lever and pressure wheel toward the feed wheel and establishing resilient engagement between the feed wheel and pressure wheel with the solder wire in the barrel, wherein the guide means includes a guide tube releasably secured to the forward end of said barrel member and projecting outwardly therefrom, a heating unit including a cylinder extending forwardly from said barrel and terminating in a soldering tip located outwardly of said wire guide tube, said cylinder having a longitudinal axis parallel to said guide tube, a clamp means coupled to said cylinder and including depending means extending downwardly to said guide tube, releasable means to firmly clamp said clamp means to said cylinder and to said guide tube to support said guide tube in predetermined orientation with respect to said cylinder and said soldering tip, said clamp means permitting angular displacement of said tube about said cylinder and in the plane through the longitudinal axis of said cylinder for optimum orientation of said wire guide tube with respect to said soldering tip.

A soldering gun apparatus for hand manipulation and for feeding solder wire to work, comprising a plastic housing including a barrel portion and an integrated depending handle portion, a heater cylinder secured to the forward end of said barrel portion and extending outwardly therefrom, a soldering tip unit secured to the outer end of said cylinder and having an outer portion extending at an angle to said cylinder and terminating in a solder melting cone-shaped tip, a wire guide secured to the forward end of said barrel beneath said cylinder and extending outwardly into alignment with the underside of said tip, a clamp unit including a generally U-shaped clamp member having a portion encircling said cylinder and having parallel depending arms extending downwardly to the opposite sides of said guide tube, a clamping bolt unit passing through said arms between said cylinder and said guide tube and operable to clamp said arms and thereby secure said guide tube in fixed relation relative to said cylinder, said clamp unit establishing angular orientation of said guide tube with respect to said tip and linear orientation of said guide tube between said clamping arms, a ratchet wheel rotatably mounted within said handle portion, a trigger unit coupled to rotate said wheel for moving of said solder wire through said barrel portion, a pressure wheel located within said barrel and in opposed alignment with said ratchet wheel and operable to hold said solder wire in engagement with said ratchet wheel, a pressure wheel lever pivotally mounted in said housing, said pressure wheel being rotatably mounted on said lever, said lever including an upwardly and outwardly extending stem, a spring member coupled to said stem and pivoting said lever to move said pressure wheel towards the ratchet wheel, a release means secured to said lever and extended through the outer wall of said housing to permit manual positioning of said lever to compress said spring and hold said wheel spaced from said solder wire.
