Abstract Horizontal rolls define troughs between them for reception and support of whole citrus fruit, each roll including a plurality of thin metal rings mounted in axially spaced relationship, each ring having a continuous series of pointed teeth on its periphery, and each ring being inclined to its rotary axis whereby rotary movement of the rings causes wobble movement of the disk peripheries so that penetration of the teeth is substantially uniform over the entire outer surface of each fruit. The rolls are turned in the same direction, each successive roll in a series turning at a slower speed. Washers are positioned between each pair of toothed rings and are free to move radially to prevent buildup of seeds, buttons, pieces of peel or other foreign matter on the toothed rings.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
145 words
Apparatus for extracting oil from the rind of whole citrus fruit, comprising, in combination: a plurality of parallel horizontal rolls defining troughs between them for reception and support of whole citrus fruit, each roll comprising a shaft having an axis of rotation, a series of parallel rings mounted in inclined position on the shaft, each ring being formed of thin metal and having a continuous series of pointed teeth on its periphery, a plurality of spacer disks each mounted on the shaft between two adjacent rings, means for clamping said metal rings and spacer disks end to end, a plurality of annular washers each loosely encircling a spacer disk and having clearance space between adjacent rings, whereby rotary movement of the shaft, rings and spacers causes wobble movement of the disk peripheries, radial movement of the washers serving to displace material accumulating between adjacent rings.

Dependent Claim
