Soldering irons

A gas heated soldering iron comprising a soldering head, a combustion chamber in said head, a flame suppression barrier enclosing said chamber, a bunsen tube for supplying a combustible gas/air mixture to said chamber, a jet directing gas into said bunsen tube, an air inlet aperture for supplying air to gas issuing from the jet, air control means for controlling the amount of air drawn in through said air inlet aperture, and a valve mechanism for automatically regulating the pressure of gas supplied for combustion.

A gas heated soldering iron comprising an elongate tubular stem, a soldering head at one end of said stem, a combustion chamber within said head, means at the other end of said stem for releasably receiving a container of pressurized gas to serve as a handle for said soldering iron, means resisting axial release of said container but permitting release under the action of non-axial forces, means for effecting gas flow communication between the interior of the container and said chamber, and means for admitting air to the gas flow to form a combustible mixture.

A gas heated soldering iron comprising a stem, a bunsen tube extending from one end of said stem, jet means for supplying gas to said bunsen tube, air inlet means for forming a combustible mixture with said gas, a hollow soldering head having a combustion chamber enclosed by flame suppression means, said bunsen tube having its outlet within said chamber, and means electrically insulating said head from said bunsen tube and said stem.

A gas heated soldering iron comprising a stem, a soldering head at one end of said stem, a jet for supplying gas to a combustion chamber within said head, means for supplying air to said gas to form a combustible mixture, means disposed at the other end of said stem for releasably receiving a gas container which serves as a handle for said soldering iron, gas flow regulating means for providing an automatically regulated flow of gas from said container, means extending axially of said stem for communicating said gas to said jet, and means operative on rotation of said stem to adjust said gas flow regulating means and vary the pressure of gas supplied to said jet.

A gas heated soldering iron comprising a stem, a soldering head at one end of said stem, a jet for supplying gas to a combustion chamber within said head, means for supplying air to said gas to form a combustible mixture, gas flow regulating means at the other end of said stem for providing an automatically regulated flow of gas from a container, means communicating an outlet of said gas flow regulating means with said jet, and a container holding member for releasably receiving a gas container, said holding member being rotatable with respect to said gas flow regulating means and movable axially in response to such rotation, means being effective on rotation of said container and holding member to adjust said gas flow regulating means and vary the pressure of gas supplied to said jet.

A gas heated soldering iron comprising a soldering head, a combustion chamber in said head, perforate flame suppression means enclosing said chamber, jet means in flow communication with a container of pressurized gas, a passage interconnecting said jet means and said chamber for supplying gas from said jet to said chamber, air inlet means for admitting air to said passage at a location remote from said chamber to form a combustible mixture, means for receiving a pressurized gas container having a depressible valve, means for controlledly depressing said valve to release gas from said container, and means responsive to pressure fluctuations in the gas flow to control the force exerted on said valve by said depressing means to ensure an automatically regulated flow of gas to said jet.

A gas heated soldering iron comprising an elongate stem, a soldering head at one end of the stem, carrying means adapted to receive a container of pressurized gas at the other end of the stem, a combustion chamber in said head, flame suppression means enclosing said chamber, jet means connectible to a source of pressurized gas, a passage interconnecting said jet means and said chamber, air inlet aperture means into said passage remote from said chamber for supplying air to gas issuing from said jet means, an insulating casing surrounding said stem and shielding said air inlet aperture means, said casing being spaced from said stem and defining an air-flow conduit from one end of said stem to the other, and means for admitting air into the conduit being provided adjacent the said other end of the stem.
