Whipper

A whipper comprising, in combination,

• a gear housing,
• a bowl of substantially uniform cross section having side walls and a base,
• a bowl skirt depending from said gear housing proportioned to coact with the sidewalls of the upper portion of the bowl,
• a support interiorly of the gear housing for a plurality of gears,
• said support having a peripheral ring,
• an interlocking key element on said ring,
• an interlocking key element interior of said gear housing,
• an opening in said housing for penetration by a crank,
• said key elements being positioned and coordinating whereby on rotation of the same the opening in the housing for positioning of the crank is fixed,
• and drive shaft means interior of the housing and secured to the support,
• and means on one end of said drive shaft for interlocking said crank,
• whereby upon insertion of the crank through the opening in the housing the interlocking between the housing and the support is secured by the penetration of the crank through the opening in the housing.

An orbital whipper comprising, in combination,

• a gear assembly including a ring gear and a plurality of beater gears coacting with the ring gear,
• a beater plate journaling the beater gears for orbital movement while the beater gears rotate,
• a plurality of beaters removably secured to the beater gears,
• a crank,
• a bevel gear means and a drive shaft coupling the crank to rotate the beater plate and beater gears,
• said crank rotating in a plane substantially perpendicular to the plane of the ring gear and beater plate,
• said plurality of beaters comprising at least three beaters located on equidistant radial and circumferential spacing each from the other beneath the beater plate,
• each beater having at least three depending tines open ended at their lower extremities and each beater being interchangeable with the others,
• said gear assembly being connected to rotate all beaters in one direction and orbit the beaters in the opposite direction,
• said gear assembly having a ring gear plate,
• said bevel gear means having a bevel gear secured to the drive shaft,
• said bevel gear means having a beater bevel gear journaled in the ring gear plate and secured to the adjacent beater plate,
• said bevel gear to said beater bevel gear having a 2:1 ratio and said ring gear to said beater gears having a 5:1 ratio, whereby these ratios result in two orbits of the beater plate for each rotation of the crank and ten rotations of the beaters for each rotation of the crank,
• whereby the gear assembly, beaters and crank is a free standing assembly atop the open ends of the beater tines for storage and drainage of the beaters.

An orbital whipper comprising, in combination,

• a gear housing,
• a crank,
• a beater plate at the bottom of said housing,
• a plurality of beater gears each having a depending spline extending downwardly through the beater plate,
• collars surrounding a portion of said beater gear splines extending downwardly from the beater plate,
• an inwardly extending collar interiorly of the beater gear spline defining a neck therein,
• a plurality of beaters having sockets thereatop proportioned to receive the beater gear splines and collars,
• a snap acting split head in the socket and beater gear spline to removably secure the beater to the beater gear when inserted into the beater gear collar.

An orbital whipper for a plurality of beaters, and a removable beater characterized by,

• means for rotating a beater,
• a beater,
• a socket atop the beater,
• said socket having means for removably securing the same to the orbital whipper,
• a plurality of parallel open ended tines extending downwardly from said socket,
• each tine having opposed knife edges,
• each tine having a central thickened section and uniform cross section of isosceles trapezoidal configuration,
• each tine having a centrally curved lower extremity, the curve being less than 45.degree.,
• said lower extremity having a central thickened portion,
• all said lower extremities terminating in a plane perpendicular to the axis of the tines,
• whereby the thickened portion of the tine drives mixed substances centrally of the beater and the lower curved portion strips the bottom of a bowl and yet upon withdrawing the beater from the mixed substances they will drain from the lower curved ends of the tines.

In a whipper having a gear housing assembly, including a ring gear plate and a beater plate, said ring gear plate having a ring gear, a drive shaft secured to the ring gear plate in substantially parallel orientation with the plane of the ring gear, 90.degree. gear means secured to said drive shaft, a crank for rotating the drive shaft to actuate the 90.degree. gear means to rotate the beater plate, a plurality of beater gears journaled within the beater plate to coact with the ring gear, each of said beater gears having beater securing means extending downwardly therefrom and through the beater plate, the improvement consisting essentially

• a plurality of beaters coupled to the beater securing means,
• said plurality of beaters comprising three beaters located on equidistant radial and circumferential spacing each from the other beneath the beater plate,
• all of said beaters having a gear connection coacting with the ring gear formed and proportioned so that each beater rotates in the same direction as the adjacent beater,
• all of said beaters being positioned with reference to the beater plate so that said beaters rotate in the same orbital path,
• and said gear means to rotate on the beater plate being connected to rotate said beater plate in a direction opposite the direction of rotation of each such beater,
• the beaters being of uniform size and length and interchangeable,
• each beater having open ended depending tines of uniform length,
• said tines each having a linear uniform cross-section with lateral edges defining oppositely disposed cutting edges, whereby the beater assembly separated from the bowl is free standing in the upright position to facilitate interim positioning and promote drainage cleaning of the beater tines.
