Abstract
Abstract A cutting assembly for cutting vegetable products, such as potatoes and the like, into a longitudinally extending central core and a plurality of longitudinally extending outer strips having a generally arcuate cross section. The cutting assembly is preferably mounted along an hydraulic flow path for passage of the product one at a time at a relatively high velocity into cutting engagement with the assembly. The cutting assembly includes a housing and a cylindrically-shaped core knife in the housing which defines a circular leading cutting edge along the axis of the flow path. A plurality of radially extending strip knives are angularly arranged between the core knife and the housing to support the core knife in position and to define radially extending leading cutting edges for engaging the product. The core knife and the strip knives also cooperate with the housing to define flow paths through the cutting assembly of substantially constant cross section for separate passage of the appropriate product pieces without substantial reduction in the applied hydraulic pressure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
155 words
A cutting assembly for dividing a product such as a potato into a generally cylindrical central core and a plurality of longitudinally extending outer strips each having a generally arcuate cross section, comprising: an exterior housing having a central longitudinal passage formed therein; a generally cylindrical hollow core knife having a generally circular cutting edge at one axial end thereof and being sized for reception into said housing generally along the axis of said passage; and a plurality of strip knives each extending radially between said housing and said core knife for structurally supporting said core knife with respect to said housing and including a cutting edge presented in the same direction as said core knife cutting edge, said core knife and said strip knives being operable to divide the product into the core for passage through said core knife and said plurality of outer strips for passage between said core knife and said housing.
Claim 2
Dependent Claim
155 words
A cutting assembly for dividing a product such as a potato into a generally cylindrical central core and a plurality of longitudinally extending outer strips each having a generally arcuate cross section, comprising: an exterior housing having a central longitudinal passage formed therein; a generally cylindrical hollow core knife having a generally circular cutting edge at one axial end thereof and being sized for reception into said housing generally along the axis of said passage; and a plurality of strip knives each extending radially between said housing and said core knife for structurally supporting said core knife with respect to said housing and including a cutting edge presented in the same direction as said core knife cutting edge, said core knife and said strip knives being operable to divide the product into the core for passage through said core knife and said plurality of outer strips for passage between said core knife and said housing.
Claim 3
Dependent Claim
24 words
The cutting assembly as claimed in Claim 1 wherein said core knife has a central longitudinal passage formed therethrough of substantially constant cross section.
Claim 4
Dependent Claim
51 words
The cutting assembly as claimed in Claim 1 wherein said strip knives and said core knife cooperate with said housing to define a plurality of longitudinal passages between said core knife and said housing, each of said plurality of longitudinal passages having a substantially constant cross section throughout the length thereof.
Claim 5
Dependent Claim
30 words
The cutting assembly as claimed in Claim 3 wherein said cutting edges of said strip knives are disposed generally in the same radial plane as said core knife cutting edge.
Claim 6
Dependent Claim
82 words
The cutting assembly as claimed in Claim 1 wherein said core knife has a plurality of radially outwardly open and longitudinally extending slots formed in the outer diameter surface thereof, and wherein said housing has a corresponding plurality of radially inwardly open and longitudinally extending slots formed -in the inner diameter surface thereof in alignment with said core knife slots, said strip knives each being removably receivable within one of said core knife slots and an aligned one of said housing slots.
Claim 7
Dependent Claim
78 words
The cutting assembly as claimed in Claims 1 or 5 wherein said core knife has a longitudinally extending central passage formed therein, and an outer diameter surface having a generally cone-shaped configuration progressively expanding radially outwardly from said core knife cutting edge to the opposite axial end thereof, and wherein said central longitudinal passage in said housing has an inner diameter surface progressively expanding radially outwardly generally in parallel with said outer diameter surface of said core knife.
Claim 8
Dependent Claim
71 words
The cutting assembly as claimed in Claim 6 wherein each of said core knife slots is formed over at least a portion of said outer diameter surface axially opposite said core knife cutting edge, and wherein each of said strip knives has a radially inner edge shaped for mating reception into one of said core knife slots and for mating engagement with the remaining length of said core knife outer diameter.
Claim 9
Dependent Claim
44 words
The cutting assembly as claimed in Claim 1 further including means fixed in position relative to said housing and connected to the end of said core knife opposite said core knife cutting edge for structurally supporting said core knife with respect to said housing.
Claim 10
Dependent Claim
37 words
The cutting assembly as claimed in Claim 1 including means coupled to said core knife at its axial end opposite said core knife cutting edge for dividing said core into a plurality of relatively small longitudinal strips.
Claim 11
Dependent Claim
70 words
The cutting assembly according to any one of the preceding claims in combination with an hydraulic pressure conduit, means for propelling the product one at a time through said pressure conduit along with a propelling hydraulic fluid, an inner discharge conduit, and an outer discharge conduit positioned generally concentrically about the inner discharge conduit, the exterior housing of_the cutting assembly being connected between said pressure conduit and said outer conduit.
