Electric Kettle: Immersion Heater with a Steam and Switch-On-Dry Cut-Out (Taylor, US 4,358,666)
An automatic electric kettle boils water with an immersion heater and switches itself off. J. C. Taylor (US 4,358,666, 1982) mounts one control on the heater's head: a bimetal disc touching the hot head cuts the power if the kettle is switched on dry, and a second bimetal disc in the steam trips an over-centre lever that cuts it when the water boils.
In his kettle (Fig. 14) the steam leaves through a hole high in the wall and runs down a passage between the handle and the wall to the control. A knob resets it.

"The effect is that when the water boils, the lever 16 is tripped by the actuator 22 from its first to its second position, thus interrupting the supply of electricity to the heating element."

Fit the immersion heater
Make the kettle body with a spout, lid and handle, an opening low in the back wall for the heater head and a hole high in the wall under the handle for steam. Fix the immersion heater's head watertight in the low opening, with its element low in the kettle and its hot return brazed to the head so the head heats up if the element runs dry. Form a steam passage between the handle and the wall from the high hole down to the head. Body material, size and heater rating are not given.

Build the switch-on-dry unit
On the head mount a switch unit with three pins (line, neutral and earth) for the kettle lead's socket. Wire the line pin to one cold end of the element through a movable contact on a springy conductive strip and a fixed contact. Rivet the tongue of a snap-acting bimetal disc to a pillar so its body touches the head. Fit a sliding link that the disc pushes: at about 120 °C (Taylor: "say 120° C.") the disc snaps over and the link parts the contacts.

Press a disc of sheet bimetal into a domed die, with a cut-out that leaves a tongue in the middle, so it snaps over when steam heats it. Mount it by its rim on a lever that rocks on two knife edges in notches of a body seated over the switch unit, held by two over-centre C-springs, with a shroud round the pins and a steam opening sealed by an O-ring. A finger of the lever passes through the sliding link; a knob on the lever comes out through the housing. The trip temperature and bimetal grade are not given.

Close up and use
Close up and use
Screw the outer housing over both units into the threaded pillars, the knob through its opening and the steam passage meeting the steam unit's channel. Fill, plug in the lead and press the knob down to close the contacts. When the water boils, steam reaches the disc, the lever snaps over and the power goes off; switched on dry, the head heats and the other disc cuts it and holds the lever off. Press the knob to reset.
