Abstract
Abstract The machine includes an alignment section, such as including oppositely rotating pairs of spiral rolls, which receive the onions from a front conveyor and move the onions toward a cutter for removing the tops and placing the onions, top down, during such movement. a paddle wheel having flexible blades, beneath the alignment rolls, urges the tops toward the cutter, while a flexible skirt is engaged by the blades to wipe the onion tops off the blades. A conveyor, which receives the topped onions from the cutter, is used as a picking table, for culling purposes, while the onions are delivered through hollow, upright chutes into sacks, with reversible plates in the chutes for directing the onions to alternate sacks, and handle-operated bars for moving a sack off hooks, at the lower edge of the chute opposite the operator.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
171 words
In apparatus for harvesting onions and the like: a. alignment means for moving onions from a leading end thereof across to a discharge end thereof and at the same time orient and turn said onions to a top-down position with the onion tops depending from the alignment means; b. cutter means at the discharge end of the alignment means for severing the onion tops; c. means beneath said alignment means adjacent to said cutter means for urging said depending onion tops toward said cutter means, said top urging means being mounted upon a rotatable shaft disposed parallel to the discharge end of said alignment means and including blade sections radially outstanding from the shaft for movement underneath and adjacent to both said alignment means and said cutter means and toward said cutter means as an incident of rotation of the shaft; and d. a depending skirt formed of resilient but relatively stiff material and disposed in position to be engaged by said blade sections after movement thereof beneath said cutter means.

Claim 3
Dependent Claim
21 words
In the apparatus defined in claim 1, wherein: said blade sections are flat, rectangular sheets of comparatively stiff but resilient material.
Claim 4
Independent Claim
170 words
An apparatus for harvesting vegetables, such as onions, by picking up such vegetables, topping the same and thereafter conveying the same for sacking, including: a sacking chute having walls forming a rectangular boxlike structure open at the top and bottom and through which vegetables may move, said chute being proportioned so that two open-mouth sacks may be placed at the bottom thereof to receive vegetables falling into the chute and each of two opposing walls of said chute having a pair of disjoined, oppositely inclined, downwardly converging slots; a deflector plate within said chute adapted to overlie one sack and to deflect vegetables falling thereon into the other sack; supporting means extending from each corner of the deflector plate and through a corresponding slot; a handle connected to said supporting means at one wall of said chute for shifting the deflector plate from one side of the chute to the other to deflect vegetables into a selected sack; and means for releasably holding the respective sacks in position for filling.
