Abstract: Deflector at top of toasting chamber enhances flow of cooling air in a space between the outer cover of a toaster and the inner wall of a "double wall" structure by projection inward relative to the top opening in the toaster cover.

Abstract: An overtemperature protector for an appliance having an electrical heating element includes a fixed contact, a movable contact carried by a spring blade and settable into engagement with the fixed contact to complete the energizing circuit to the heating element by stressing the spring blade, and a torsion spring having an arm engageable with the spring blade to hold the contacts in engagement against the stress bias of the spring blade. A fusible pin retains the arm of the torsion spring in engagement with the spring blade, thus locking the contacts closed. Excessive heat in the appliance causes the pin to soften, thereby allowing the torsion spring to shear the pin and release the movable contact to open the heating element energizing circuit.

Abstract: An overtemperature protector for an appliance having an electrical heating element, the overtemperature protector being formed basically of just a spring blade positionable to bring a contact on the surface of the blade into circuit-energizing engagement with a fixed contact, and an insulator-capped fusible pin retaining the blade in that position. Excessive heat in the appliance softens the pin, allowing the spring blade force on the insulator cap to shear the pin and interrupt the circuit. The overtemperature protector is preferably incorporated in a thermostatic control, the fixed contact being supported on a lateral extension projecting from one circuit element of the thermostat assembly and the spring blade being supported within the assembly with an insulating spacer separating it from the thermostat element having the lateral extension. The spring blade is preferably sickle-shaped for compactness despite having a long length for low force to minimize effects of creep of the fusible pin.

Abstract: Pump chambers usable in beverage makers, for example, have a liquid-contacting heated surface provided with abrupt discontinuities--e.g. sharp edges or corners--to promote flaking-off of mineral deposits. These edges may be fins of rectangular or triangular cross-section.

Abstract: An electric steam-spray iron having a pump and a bi-stable valve in a single housing for drawing water from a reservoir and delivering it to either a spray nozzle or a steam generating chamber which communicates with steam ports in the sole plate. The valve's stable state is changed by rocking movement of the pump's piston.
