Abstract
A planetary-type kitchen mixer-kneader having two spindles both of which turn in the same direction and travel in identical circular orbits as they sweep in an orbital path along the inside wall surfaces of the mixing bowl. The spindles are adapted to carry wire whips, flat beaters, and dough hooks, the latter in pairs which cooperate by means of their shapes and deflector blades, to simultaneously mix and work the dough and retain it low in the bowl.
Claims9
A planetary kitchen mixer-kneader, comprising in combination:
- (a) a rotary head mounted for rotation about a vertical axis,
- (b) a fixedly mounted gear having teeth, and having the same axis as the vertical axis of the rotary head,
- (c) power means including gearing, for rotating said rotary head,
- (d) a pair of vertical spindles turnably mounted in the rotary head and having pinions meshing with the teeth of the fixed gear to effect like-direction turning of the spindles as the head is rotatably driven,
- (e) a pair of dough hooks respectively carried by said spindles, and
- (f) a mixing bowl disposed about said dough hooks, said hooks traversing the inside surface of the bowl in an orbital path as the head turns, and said hooks having laterally-offset portions which are complementary in providing clearance between the hooks during the like-direction turning of the latter.

An anti-climb dough hook attachment for electric mixers, comprising in combination:
- (a) a hub adapted to be secured to the spindle of a mixer,
- (b) a hook carried by and depending from said hub, and
- (c) a pair of angularly-disposed blades having opposite flat sides which are disposed in oblique planes with respect to the axis of the hook, said blades being rigid with the hook and hub, and depending from the latter,
- (d) said blades being disposed on opposite sides of the hook and having an inclination which tends to force dough downwardly of the hook as it rotates about its axis.
