  • Patent number: 4289953
    Abstract: A solder extractor includes a tubular heater and removable tip carrying front unit having a rear cowl of heat insulating material and a relatively oblique rear unit including a tubular handle of heat insulated material and having a front portion with longitudinal outer ribs telescoping the cowl and separably secured thereto by screws. A transparent solder receiver tube is separably housed in the handle and its front end releasably engages a seal plug carried by a conveyor tube extending from the heater bore and its rear end is sealed by a tube coupling carrying closure member which is releasably locked to the handle member. A cooperating window in the cowl and handle permit continuous viewing of the juncture of the tip extension and the solder receiver tube. The handle has a longitudinal channel which slidably houses an electric cable connected to the heater and permits the handle to be slid rearwardly on the cable when the handle is detached from the cowl.

  • Patent number: 4230250
    Abstract: The solder extractor includes a hollow handle rear section housing a suction connected receiver and a front section carrying an electrically heated tubular tip and a coaxial communicating rearwardly projecting coupling tube. One of a pair of end-to-end hinged posts projects forwardly and eccentrically from the rear section and the front section is coupled to the other post by an elongated bolt slidably engaging axial bores in the posts and screw engaging the rear section. In operative position the post are coaxially locked and the rear section secured to the posts with the coupling tube connected to the receiver by the tightened bolt and to position the sections for cleaning the bolt is retracted to allow retraction of the front section and coupling tube and to relatively unlock the posts to permit the swinging of the rear section affording access to the bore therethrough for cleaning.
