Abstract
Abstract A rounded food article, such as a tomato or potato, is quickly 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 fingers depending from a plunger to which a handle is attached. The plunger assembly slides over a pair of vertical guides 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 plunger includes obstructing tabs in the event both vertical rods are not properly engaged in the plunger, such that the plunger is angularly displaced and the fingers strike the base rather than the blades or spike. Four legs give the device a steady foundation and raise the base sufficiently from the table to allow the long food sections to be freely discharged onto it.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
139 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, slide guide means connected to the base, a plunger having an outer perimeter having slide guide ways located at the outer perimeter of the plunger in which the slide guides engage, the plunger transversing towards the base and returning along the slide guide means, the plunger having slide guide obstructing tabs attached to the outer perimeter of the plunger adjacent on each side of the slide guide ways causing the plunger to rotate when the plunger is installed inproperly without all the slide guide ways cooperating with the slide guides such that the plunger strikes the base rather than said blades;
Claim 2
Independent Claim
139 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, slide guide means connected to the base, a plunger having an outer perimeter having slide guide ways located at the outer perimeter of the plunger in which the slide guides engage, the plunger transversing towards the base and returning along the slide guide means, the plunger having slide guide obstructing tabs attached to the outer perimeter of the plunger adjacent on each side of the slide guide ways causing the plunger to rotate when the plunger is installed inproperly without all the slide guide ways cooperating with the slide guides such that the plunger strikes the base rather than said blades;
Claim 3
Dependent Claim
174 words
an annular array of fingers depending from the plunger 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, the fingers being long enough to substantially pass through the blades when the movement of the plunger into engagement with the base is terminated, stop means on the base and plunger for terminating their engagement with each other, 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.
Claim 4
Dependent Claim
174 words
an annular array of fingers depending from the plunger 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, the fingers being long enough to substantially pass through the blades when the movement of the plunger into engagement with the base is terminated, stop means on the base and plunger for terminating their engagement with each other, 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.
Claim 5
Dependent Claim
24 words
A device as set forth in claim 1 wherein the base has four legs with a range of heights from 7 to 9 inches.
Claim 6
Dependent Claim
34 words
A device as set forth in claim 1 wherein the plunger has a handle parallel to the top surface of the plunger and 2 and 3 inches from the surface top of the plunger.
Claim 7
Dependent Claim
19 words
A device as set forth in claim 1 wherein there are six wedged-shaped spaces between the radially mounted blades.
Claim 8
Dependent Claim
19 words
A device as set forth in claim 1 wherein there are eight wedged-shaped spaces between the radially mounted blades.
Claim 9
Dependent Claim
22 words
A device as set forth in claim 1 wherein the diameter of the radially sharp blades is between 3 and 4 inches.
Claim 10
Dependent Claim
24 words
A device as set forth in claim 1 wherein the included angle of the conical cup of blades is between 75 and 105 degrees.
Claim 11
Dependent Claim
24 words
A device as set forth in claim 1 wherein the slide guides consist of two rods of diameter ranging from 1/4 to 1/2 inch.
Claim 12
Dependent Claim
29 words
A device as set forth in claim 1 wherein the plunger contains four slide guide ways; two on each side separated by a 1/4 to 3/4 of an inch.
Claim 13
Dependent Claim
24 words
A device as set forth in claim 1 wherein the length of the fingers connected to the plunger are 2 to 23/4 inches long.
Claim 14
Dependent Claim
24 words
A device as set forth in claim 1 wherein the length of the slide guides is in the range of 8 to 10 inches.
