Handle for kitchen tools

An agitator assembly for a blender appliance including a diaphragm closure for the bottom opening in a blender vessel with a pair of spaced bearings supported on said diaphragm and a two-piece shaft assembly to interconnect the motor drive and the comminuting blades, the two-pieces being coupled by a spline connection which eliminates the need for accurate bearing alignment.

Agitator assembly for use in blender appliance

A motor control circuit is provided for an appliance or the like of the type utilizing a speed adjustment device that controls an adjustable centrifugally controlled governor device. The governor includes a switch contact arrangement which is connected in the triggering circuit of a power switching device, a TRIAC for example, for selectively connecting the motor of the appliance to the power source connections. The switch contacts of the governor device open and close as the rotational speed of the motor increases and decreases respectively from the speed selected on the speed adjustment device. A variable impedance element mechanically coupled to and adjusted by the speed adjustment device is also provided in the triggering circuit of the power switching device in series with the governor switch contacts to vary the triggering of the power switching device as the speed setting is varied. Thus, a variable speed versus motor supply voltage characteristic is provided when the governor contacts are closed. A wider range of stable speed control is provided than is obtained with a governor device alone. Low speed cogging and high speed hunting problems are also minimized. The variable impedance element in various embodiments is arranged to provide a variable impedance characteristic over a portion of the speed adjustment device range and a fixed impedance over the remainder of the range.

Speed responsive motor control circuit

An automatic control for egg cookers, baby bottle warmer, etc. is designed around a conventional slide switch of the type normally biased to the open position. Manually actuated means are provided to move the slide switch to its ON position, whereupon a mechanical latch automatically latches onto the knob of the slide switch to hold it in its ON position. When the cooking has been completed, a bi-metal releases the latch and permits the biasing means to open the switch and terminate the heating.

Automatic control for electric heating device

A multi-purpose kitchen appliance having two pairs of output spindles with each pair being driven at different preselected speeds, one pair of said spindles having dough hook receiving bores and the other pair having mixing beater receiving bores, a turntable-supported bowl with said dough hooks and said mixing beaters being selectively disposed in said bowl for mixing material therein, interlock means preventing simultaneous driving engagement of said dough hooks with their spindles and said mixing beaters with their spindles, and means for selectively ejecting said dough hooks and said mixing beaters from said pairs of spindles.

Multi-purpose kitchen appliance

A multi-purpose kitchen appliance for performing the functions of food mixing, blending, and the grinding or chopping of food. A power unit includes a low speed and a high speed power delivery shaft at the upper end thereon which are connectable alternatively to a blender vessel or a transversely extending head including gearing to drive a pair of food mixing elements. The head for driving the mixing elements is provided with means for detachably supporting and driving other attachments such as a food grinder. The power unit rests on a base having a laterally extending portion which has a turntable supporting a bowl into which the food mixing elements extend when the transversely extending head is positioned for food mixing. The transverse head is mountable on the power unit in alternate positions so that by connecting the food grinder to the gear train in the head, the chopped food or meat may be delivered to the bowl position on the turntable. The head is provided with means to pivotally connect it to the power unit or to rigidly latch the head in a fixed position with respect to the power unit.
