Abstract
Abstract A rounded food article, such as a lemon, tomato or apple, is instantaneously divided into a number of radial sections by forcing it through a conical cup of radial blades within which it is impaled on a central spike to which the central ends of the blades are joined. The article is forced through the wedge-shaped spaces between the blades by an annular array of bent rod fingers depending from a head to which an operating handle is attached. The plunger assembly slides over a pair of vertical rods towards the blade assembly engaged within a recess in the base. The fingers extend completely through the blades when the plunger is fully engaged within the blades. The substantial weight of the plunger facilitates its rapid downward movement toward the blade, and a set of three legs raise the base sufficiently from the table to allow the food sections to be freely discharged onto it.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
308 words
A device for sectioning a rounded food article comprising a base, a conical cup of internally sharp radial blades mounted in the base and having an apex disposed towards the base with substantially wedge-shaped spaces between the blades, a plunger, slide guide means connecting the plunger for reciprocating movement towards the base and return, the plunger including a annular array of fingers depending from it which freely engage within the wedge-shaped spaces between the radial blades when the plunger is moved towards the blades, the fingers each comprising a linear element having two ends, one end of each of the fingers being attached to the plunger and the other end being free, stop means on the base and plunger for terminating their engagement with each other, the fingers being long enough to substantially pass through the blades when the movement of the plunger into engagement with the base is terminated, a spike having a point and a stem centrally mounted at the central junction of the blades to form their apex disposed within the cup, the point of the spike extending upwardly adjacent the entrance to the cup for holding the article aligned for engagement by the plunger and for initiating the radial splitting of the article which is continued and completed by the blades, the stem of the spike freely terminating a short distance below the cup of blades, the fingers each comprising an elongated resilient rod having an inwardly bent foot, the inwardly bent feet terminating in a circular array leaving a circular space between their ends for receiving the spike, the inwardly bent feet also being upwardly inclined from their junctions with the rods to inwardly disposed ends whereby the rods are guided through the wedge-shaped spaces with their feet in smooth contact with the article they are pushing through the conical cup of blades.

A device for sectioning a rounded food article comprising a base, a conical cup of internally sharp radial blades mounted in the base and having an apex disposed towards the base with substantially wedge-shaped spaces between the blades, a plunger, slide guide means connecting the plunger for reciprocating movement towards the base and return, the plunger including a annular array of fingers depending from it which freely engage within the wedge-shaped spaces between the radial blades when the plunger is moved towards the blades, the fingers each comprising a linear element having two ends, one end of each of the fingers being attached to the plunger and the other end being free, stop means on the base and plunger for terminating their engagement with each other, the fingers being long enough to substantially pass through the blades when the movement of the plunger into engagement with the base is terminated, a spike having a point and a stem centrally mounted at the central junction of the blades to form their apex disposed within the cup, the point of the spike extending upwardly adjacent the entrance to the cup for holding the article aligned for engagement by the plunger and for initiating the radial splitting of the article which is continued and completed by the blades, the stem of the spike freely terminating a short distance below the cup of blades, the fingers each comprising an elongated resilient rod having an inwardly bent foot, the inwardly bent feet terminating in a circular array leaving a circular space between their ends for receiving the spike, the inwardly bent feet also being upwardly inclined from their junctions with the rods to inwardly disposed ends whereby the rods are guided through the wedge-shaped spaces with their feet in smooth contact with the article they are pushing through the conical cup of blades.
Claim 3
Dependent Claim
28 words
A device as set forth in claim 1 wherien the junctions of the elongated rods with their inwardly bent feet are curved and are disposed below the feet.
Claim 4
Dependent Claim
17 words
A device as set forth in claim 2 wherein the elongated rods comprise relatively thick metal wires.
Claim 5
Dependent Claim
37 words
A device as set forth in claim 3 wherein the inner ends of the feet are disposed in a circular array which substantially closely receives the spike between them when the fingers engage within the wedge-shaped spaces.
Claim 6
Independent Claim
16 words
A device as set forth in claim4 wherein the metal wires are about 1/8 inch thick.
Claim 7
Dependent Claim
67 words
A device as set forth in claim 1 wherein the upper arms of the rods adjacent the plunger are inwardly bent, the plunger having a hub disposed on its lower end between the elongated rods, and securing means removably attaching the hub to the bottom of the plunger with the upper bent arms of the rods removably captured between the hub and the bottom of the plunger.
Claim 8
Dependent Claim
78 words
A device as set forth in claim 6 wherein the inner extremities of the upper arms are bent to lie parallel to the rods to provide locking pegs, the hub includes slots at its periphery for receiving the elongated rods, and a circular array of holes in a substantially central area of the hub for removably receiving the pegs whereby the fingers are securely attached to the hub in a relatively stiff but resilient and non-rotating annular array.
Claim 9
Dependent Claim
28 words
A device as set forth in claim 1 wherein the point of the spike is disposed approximately 1/2 inch below the mouth of the conical cup of blades.
Claim 10
Dependent Claim
28 words
A device as set forth in claim 8 wherein the bottom end of the spike extends approximately 3/4 inch below the bottom of the conical cup of blades.
Claim 11
Dependent Claim
17 words
A device as set forth in claim 8 wherein the spike is approximately 3/16 inch in diameter.
Claim 12
Dependent Claim
24 words
A device as set forth in claim 1 wherein the conical cup of blades has an included angle ranging from approximately 60° to 120°.
Claim 13
Dependent Claim
24 words
A device as set forth in claim 1 wherein the conical cup of blades has an included angle ranging from approximately 75° to 105°.
Claim 14
Dependent Claim
21 words
A device as set forth in claim 1 wherein the conical cup of blades has an included angle of about 90°.
Claim 15
Dependent Claim
36 words
A device as set forth in claim 1 wherein legs extend downwardly from the base for elevating it above a working surface to permit the sections of the food article to be discharged from the device.
Claim 16
Dependent Claim
41 words
A device as set forth in claim 1 wherein the slide guide means comprises a pair of vertical rods mounted on the base at the sides of the blades and a pair of slide bearings on the plunger engaging the rods.
