Abstract
Abstract A food-comminuting plate includes a pair of parallel rails on which a removable food-holder can be guided for reciprocation and limited rotation relative to the plate. Comminuting blades on the plate are located between the rails. The holder is a concave shell of an extent to span the rails and its hollow opens toward the comminuting plate. The shell hollow has food-impaling pins; and a plunger extends through the shell for pressing the food along the pins toward the plate as the food is reduced by comminution. The plunger and food-impaling pins are rotatable through a limited angle. Among the blades of the comminuting plate may be an elongated cutting blade having opposite ends received in slots in the rails. Such blade is adjustable relative to the general surface of the comminuting plate by mounting screws which extend through and are recessed in the rails.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
125 words
A fruit and vegetable comminuter for cutting or grating food articles, comprising a comminuting plate, a food article holder, and means guiding said food article holder for reciprocation and limited rotation relative to said comminuting plate, said food holder including a hollow housing opening toward said comminuting plate for receiving a food article therein, a plunger located in said housing, engageable with a food article therein and movable toward said comminuting plate for pressing the food article toward said comminuting plate relative to said housing and means engaged between said housing and said plunger, guiding said plunger for reciprocation relative to said housing toward and away from said comminuting plate and connecting said plunger and said housing for conjoint rotation relative to said comminuting plate.
Claim 2
Dependent Claim
125 words
A fruit and vegetable comminuter for cutting or grating food articles, comprising a comminuting plate, a food article holder, and means guiding said food article holder for reciprocation and limited rotation relative to said comminuting plate, said food holder including a hollow housing opening toward said comminuting plate for receiving a food article therein, a plunger located in said housing, engageable with a food article therein and movable toward said comminuting plate for pressing the food article toward said comminuting plate relative to said housing and means engaged between said housing and said plunger, guiding said plunger for reciprocation relative to said housing toward and away from said comminuting plate and connecting said plunger and said housing for conjoint rotation relative to said comminuting plate.
Claim 3
Dependent Claim
28 words
The comminuter defined in claim 1, and manually engageable means located exteriorly of the housing and connected to the plunger for effecting reciprocation thereof relative to the housing.
Claim 4
Dependent Claim
46 words
The comminuter defined in claim 1, in which the comminuting plate has therein a straight slot disposed with its length inclined relative to the direction of reciprocation of the food article holder with respect to the comminuting plate, and a slicing blade located in said slot.
Claim 5
Dependent Claim
51 words
The comminuter defined in claim 3, in which the blade has a central groove on one side and a corresponding ridge on its opposite side extending lengthwise of the blade, and means engaging opposite end portions of the blade to effect movement thereof toward and away from the food article holder.
Claim 6
Dependent Claim
51 words
The comminuter defined in claim 1, in which the comminuting plate has a group of hooked blades outstanding therefrom toward the food article holder, each blade including a shank having one end connected to the comminuting plate and its opposite end carrying a cantilever projection extending generally parallel to the plate.
Claim 7
Dependent Claim
83 words
The comminuter defined in claim 1, in which the comminuting plate has a plurality of rows of teeth extending lengthwise of the direction of reciprocation of the food article holder with respect to the comminuting plate, teeth in each row being staggered relative to other teeth in that row, each tooth being in the form of a wedge having a cutting corner and tapering away from such cutting corner and the cutting corners of adjacent teeth in each row facing in opposite directions.
Claim 8
Dependent Claim
65 words
The comminuter defined in claim 6, in which each tooth is elongated in the direction of reciprocation of the food article holder with respect to the comminuting plate and the teeth are arranged in pairs with the lengths of the teeth in each pair overlapping in a direction transversely of the direction of reciprocation of the food article holder with respect to the comminuting plate.
Claim 9
Dependent Claim
138 words
A fruit and vegetable comminuter for cutting or grating food articles, comprising a comminuting plate, a food article holder, and means guiding said food article holder for movement relative to said comminuting plate in a path generally parallel to the surface of said comminuting plate, said food article holder including a hollow housing opening toward said comminuting plate for receiving a food article therein, a plunger located in said housing, engageable with a food article therein and movable toward said comminuting plate for pressing the food article toward said comminuting plate relative to said housing, and a plurality of cantilever pins located in the hollow of said housing, carried fixedly thereby and projecting therefrom toward said comminuting plate to impale a food product, movement of said plunger toward said comminuting plate stripping the food article from said pins.
Claim 10
Dependent Claim
138 words
A fruit and vegetable comminuter for cutting or grating food articles, comprising a comminuting plate, a food article holder, and means guiding said food article holder for movement relative to said comminuting plate in a path generally parallel to the surface of said comminuting plate, said food article holder including a hollow housing opening toward said comminuting plate for receiving a food article therein, a plunger located in said housing, engageable with a food article therein and movable toward said comminuting plate for pressing the food article toward said comminuting plate relative to said housing, and a plurality of cantilever pins located in the hollow of said housing, carried fixedly thereby and projecting therefrom toward said comminuting plate to impale a food product, movement of said plunger toward said comminuting plate stripping the food article from said pins.
Claim 11
Dependent Claim
27 words
The comminuter defined in claim 8, in which the plunger is engaged with the pins so as to prevent rotation of the plunger relative to the housing.
Claim 12
Dependent Claim
18 words
The comminuter defined in claim 9, in which the plunger has apertures therein through which the pins extend.
Claim 13
Dependent Claim
69 words
The comminuter defined in claim 8, in which the comminuting plate has spaced parallel flanges outstanding from one side thereof, the food article holder has extensions projecting from opposite sides thereof engageable with said flanges, respectively, and rotation-limiting means carried by said extensions and engageable with said flanges for enabling substantial rotative movement of the food article holder relative to the comminuting plate, but limiting such relative rotational movement.
Claim 14
Dependent Claim
60 words
The comminuter defined in claim 11, in which the extensions taper away from the housing to tips, the root portion of each extension having an arcuate strip engageable with a flange of the comminuting plate for guiding rotation of the food article holder relative to the comminuting plate, and the rotation-limiting means are mounted on the tips of the extensions.
Claim 15
Dependent Claim
44 words
The comminuter defined in claim 8, and article-engaging means carried by the plunger and engageable with a food article to deter movement of the food article relative to the plunger in a direction transversely of the direction of plunger movement toward the comminuting plate.
