Abstract: A cordless heating tool, including a housing, a battery coupled to the housing, a heat source, a control circuit for controlling power of the heat source, one or more reflectors mounted on the housing to focus radiant energy from the heat source toward a focal region, an opening in the housing for receiving an object to be heated in the focal region.

Abstract: A heating tool, including a housing having a handle, a heat source, a control circuit for controlling power of the heat source, one or more reflectors mounted in the housing to focus radiant energy from the heat source toward a focal region, an opening in the housing for receiving an object to be heated in the focal region, and a blower directing cooling air toward the reflectors and exiting the housing.

Abstract: A handheld heating tool has a pair of elliptical reflectors with the major axes of the ellipses being at an acute angle to each other and intersecting in a focal region including one focus of each ellipse. A pair of incandescent bulbs are mounted so that each bulb filament is at the other focus of one of the elliptical reflectors. Thus, radiant energy from both bulbs is concentrated at the focal region. This focal region lies in a channel at the front of the housing of the tool. An object to be heated lying in the channel receives radiant energy from the lamps and reflectors. A blower directs cooling air toward the reflectors and along different paths within the housing to exit through the channel. One such path is between the outside of the reflectors and adjacent reflector shields.

Abstract: A pushbutton switch has a housing with a reciprocating plunger. The plunger is made in two parts with a hollow insert pressed in place to provide a slot inside the plunger with a longitudinally extending portion and a spirally extending portion. A rotatable shaft fits within the hollow insert and has a plurality of teeth at the lower end of the shaft. An electrical contact member with three circumferentially extending fingers is on the shaft over the teeth and with the fingers extending downwardly for contacting three electrical terminals in the housing to which contact may be made by external leads. When the plunger of the switch is depressed, the shaft moves downwardly and rotates without rotating the electrical contact member. When the plunger is released, the shaft also moves upwardly and rotates in the reverse direction whereupon a tooth engages a pawl extending downwardly from the contact member, advancing the contact member in rotation and changing the state of the switch.
