Abstract
A vegetable peeling device for carrots, squash, turnips and the like employs a plurality of parallel pairs of cutting blades spring loaded toward each other. The pairs of blades are stacked about a common center and they are arranged at equal angular intervals around the common center. A vegetable pushed between the stacked pairs of blades has pairs of strips of skin peeled therefrom as it passes each of the pairs of blades and emerges fully peeled.
Claims11
A vegetable peeling apparatus for peeling generally cylindrical vegetables comprising:
- at least first and second pairs of parallel knife members:
- resilient means for urging the knife members of each pair of knife members toward each other to position spaced apart by a distance of less than a diameter of said vegetable;
- guide means on the upstream side of each of said knife members, said guide means having outwardly flaring parts effective to guide said vegetable between sair pair of knife members;
- means for pushing a vegetable to be peeled completely between all of said pairs of parallel knife members, said guide means being effective for moving said parallel knife members of each pair of knife members apart a distance sufficient to accommodate the vegetable therebetween;
- means on each knife member for slicing a strip of peel from the vegetable as it is forced therepast whereby said first and second strips of peel are sliced from opposed sides of the vegetable;
- and
- said at least first and second pairs of parallel knife members being angularly offset from each other so that each pair of knife members slices first and second strips of peel from different surface portions of the vegetable.

A vegetable peeling apparatus for peeling generally cylindrical vegetables comprising:
- at least first and second cutting knife assemblies:
- each of said cutting knife assemblies including first and second opposed knife members;
- said first knife member having a first guide plate having a first angled entry portion and a first knife bar supported spaced from said first guide plate;
- said second knife member having a second guide plate having a second angled entry portion and a second knife bar supported spaced from said second guide plate;
- resilient means for urging said first and second knife members toward each other to positions spaced apart by a distance of less than a diameter of said vegetable;
- said first and second knife bars being substantially parallel;
- said first and second angled entry portions being flared outward to permit forcing a vegetable therebetween against the urging of said resilient means and effective for forcing said knife members apart a distance sufficient to accommodate the vegetable;
- means for pushing the vegetable completely through all of said at least first and second cutting knife assemblies, each of said first and second knife members being effective to slice a strip of peel from said vegetable as it is forced therepast;
- said first and second knife bars of said first cutting knife assembly being angularly disposed with respect to said first and second knife bars of said second cutting knife assembly to slice two different strips of peel from said vegetable;
- and
- means on each of said knife members for permitting pivoting of said knife member a limited angular extent about an axis parallel to said knife bar whereby surface irregularities in the vegetable are accommodated.

A vegetable peeling apparatus for peeling generally cylindrical vegetables comprising:
- at least first and second cutting knife assemblies;
- each of said at least first and second cutting knife assemblies having at least first and second knife members equally angularly spaced about an axis;
- means for urging the knife members of each cutting knife assembly toward said axis to a position spaced apart by a distance of less than a diameter of said vegetable;
- means for pushing a vegetable to be peeled along said axis successively completely between said knife members of all of said first and second cutting knife assemblies;
- guide means at the upstream side of said knife members responsive to the pushing of the vegetable between said knife members for moving said knife members away from said axis to accommodate the vegetable therebetween;
- means on each knife member for slicing a strip of peel from the vegetable as it is forced therepast, whereby at least first and second strips of peel are sliced from said vegetable at equally angularly spaced locations;
- and
- said at least first and second knife member of said first cutting knife assembly and said at least first and second knife members of said second cutting knife assembly being angularly offset from each other so that each knife member slices a strip of peel from a different surface portion of the vegetable.
