Abstract
Abstract Whole oriented onions are sliced in a slicer by holding the onions on a horizontal cutter-bearing plate and by rotating the plate to continuously remove slices from the lower ends of the onions until the onions are fully sliced. Non-oriented onions are recirculated between a feed hopper and the conveyor leading to the slicer.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
102 words
An onion slicer comprising a rotary plate, slicing knife means carried by said plate, an onion feed conveyor positioned to deliver onions tangentially to said plate, transfer means movable transversely of said conveyor operable to move onions from said conveyor onto said plate, means to position an onion on said plate for slicing by said knife means, means to continuously press said onion against said plate as it is sliced by said knife means, and means to convey onion slices away from said plate comprising an aperture in said plate to pass said slices as they are formed by said knife means.
Claim 2
Dependent Claim
102 words
An onion slicer comprising a rotary plate, slicing knife means carried by said plate, an onion feed conveyor positioned to deliver onions tangentially to said plate, transfer means movable transversely of said conveyor operable to move onions from said conveyor onto said plate, means to position an onion on said plate for slicing by said knife means, means to continuously press said onion against said plate as it is sliced by said knife means, and means to convey onion slices away from said plate comprising an aperture in said plate to pass said slices as they are formed by said knife means.
Claim 3
Dependent Claim
61 words
The slicer of claim 1 including an onion feed hopper associated with said conveyor, means to transfer onions from said hopper onto the feed conveyor, a bypass conveyor adapted to receive non-oriented onions from the feed conveyor at a transfer station and return them to said hopper, and means to transfer non-oriented onions from said feed conveyor to said bypass conveyor.
Claim 4
Dependent Claim
36 words
The slicer of claim 2, said means to transfer onions from said hopper onto the feed conveyor comprising a cyclically movable wall member for said hopper operable to prevent the bridging of onions within said hopper.
Claim 5
Dependent Claim
81 words
An onion slicer comprising a horizontally disposed rotary plate, slicing knife means carried by said plate, means to position an onion on said plate for slicing comprising a U-shaped pocket member mounted above said plate, hold-down means to continuously press said onion against said plate as it is sliced by said knife means, and means to convey onion slices away from said plate comprising an aperture in said plate to pass said slices as they are formed by said knife means.
Claim 6
Dependent Claim
81 words
An onion slicer comprising a horizontally disposed rotary plate, slicing knife means carried by said plate, means to position an onion on said plate for slicing comprising a U-shaped pocket member mounted above said plate, hold-down means to continuously press said onion against said plate as it is sliced by said knife means, and means to convey onion slices away from said plate comprising an aperture in said plate to pass said slices as they are formed by said knife means.
Claim 7
Dependent Claim
64 words
The slicer of claim 4, said hold-down means comprising a pivotally mounted arm member extending lengthwise of said pocket member and adapted to be cammed upwardly by the movement of an onion into said pocket member, and means associated with said hold-down means operable to continuously press said arm member onto an onion in said pocket member until the onion has been fully sliced.
Claim 8
Dependent Claim
48 words
The slicer of claim 5 including a feed conveyor to feed onions along a path extending at a right angle to the open end of said U-shaped pocket member, and pusher means to move onions one at a time off of said feed conveyor into said pocket member.
Claim 9
Dependent Claim
65 words
The slicer of claim 6, including means to retract said pusher means, means to position another onion in line with the retracted pusher means for movement into said pocket member, and means responsive to pivotal movement of said arm member through a predetermined angle as an onion is fully sliced to actuate said pusher means and position another onion within said pocket member for slicing.
Claim 10
Dependent Claim
62 words
An onion slicer comprising a horizontally disposed rotary plate, slicing knife means carried by said plate, means to position an onion on said plate for slicing comprising a pocket member open at the top and bottom mounted above said plate, and means to adjustably position said pocket member relative to said plate to control the clearance therebetween and thereby control slicing efficiency.
Claim 11
Dependent Claim
62 words
An onion slicer comprising a horizontally disposed rotary plate, slicing knife means carried by said plate, means to position an onion on said plate for slicing comprising a pocket member open at the top and bottom mounted above said plate, and means to adjustably position said pocket member relative to said plate to control the clearance therebetween and thereby control slicing efficiency.
