COMBINED VEGETABLE SLICER AND SLITTER Filed Apiil 16, 1945 JAM/ 26 KRILOW Patented Feb. 11, 1947 ir- STATE TEN OFFICE GOMBINED VEGETABLE SLICER AND SLITTER 4- Claims. 1 The primary object of this invention is to combine in a single hand operated utensil means for spirally slicing a vegetable and at the same time slitting the spiral as formed into a plurality of strips or ribbons.
A further object of the invention is to provide a hand utensil that cuts a vegetable into a multiplicity of continuously spiraled narrow strips in one continuous operation.
Another object of the invention is to provide a utensil that will cut a raw vegetable into a plurality of strips or ribbons of uniform size that may be made edible by a minimum of cooking to preserve the maximum vitamin content during such operation.
Still another object of this invention is to provide a well known type of hand rotatable spiral vegetable slicer with means for automatically slitting the cut spiral into strips during the spiral cutting operation.
In the drawing:
Figure 1 is a perspective view of the slicer and slitter in operation;
Figure 2 is a front view of the cutter;
Figure 3 is an end view showing the angular incidence of the screw with respect to the knife;
Figure 4 is a bottom plan view of the cutter;
Figure 5 is a section on the line 5-5 of Figure 4; and
Figure 6 is a partial section of a modified form of cutter wherein the slitting knives are formed integral.
The rotatable hand type spiral slicer for raw vegetables, usually potatoes, is well known in the art. In the type illustrated, it comprises a knife I, having a front cutting edge 2 with a finger loop 3 at one end and a penetrating screw A at the other. The screw has an angular incidence with respect to the knife that is not greater than the pitch of the screw to lead the cutting edge into the vegetable in use.
In use, the vegetable, usually a potato, is washed and pared. While held in one hand, the screw 45 is caused to penetrate the top of the vegetable and when the knife i held in the other hand with a finger in the loop fieengages the vegetable, continuous rotary operation will slice the vegetable spirally. However, the resulting spiral is half the width of the vegetable. My invention relates to an improvement on such a product wherein the spiral is slit into a plurality of ribbons or strips suitable for making a la Julienne or shoestring potatoes, etc.
In this invention, the underside of the knife I is provided with a plurality of spaced slitting knives 5. In the form shown in Figures 2, 3 and 4, the knives 5 are struck down from a base 6 and are arranged in spaced parallel relation and extend longitudinally with respect to the base 6 and knife blade. The knife I has inwardly extending slots 1 from the cutting edge 2, and the ends of the base Ii form tongues 8 extending through the slots 1. The extremities of the tongues 8 are bent over the reverse side of the knife I toward each other as clearly shown in Figure 5 to secure the base 6 and slitting knives 5 in position which will be at right angles to the knife blade.
In the modified form shown in Figure 6, the slitting knives 5 are formed integral with the knife I and are bent downward therefrom in the manner shown. The function of the slitting knives is identical in each instance only in one form they are formed separately from the knife and secured thereto while in the other, they are formed as an integral part of the knife blade.
When the utensil is used to cut a potato P, as shown in Figure 1, the slitting knives 5 will cut the spiral formed by the cutting edge 2 of the knife I into a plurality of spiraled ribbons or strips during the usual slicing operation and without varying from the usual method of operating a slicer of this character. This will automatically spirally slice the potato and slit the spiral into a pluralit of uniformly sized spiral ribbons or strips suitable for preparing shoestring potatoes or other fancy shaped vegetables.
By equally spacing the slitting knives 5, the spiral ribbons or strips formed as shown in Figure 1, are of a uniform size and have the additional advantage of reducing the cooking time of the product with a consequent preservation of the vitamin content of the prepared food. The slitting means employed in this invention does not vary or modify 'in any manner the spiral slicing operation of the utensil and results in the formation of a new product not heretofore obtainable from spiral hand slicers of this character. The combination vegetable slicer and slitter thus constructed is economical to manufacture and provides a simplified means for readily cutting the vegetable into a plurality of uniform continuous spiral strips when desired.
Other and further objects of the invention will be apparent from the detail description thereof, wherein only preferred embodiments of the invention are shown and described.
I claim:
1. A combined vegetable spiral slicer and slitter including a hand operated knife, a. penetrating screw at one end thereof, and a plurality of slitting knives carried by said knife.
2. A combined vegetable spiral slicer and slitter including a hand operated knife, a penetrating screw at one end thereof, and a plurality of spaced slitting knives extending at right angles to the plane of said knife.
3. A combined vegetable spiral slicer and slitter including a hand operated knife, a penetrating screw at one end thereof, a plurality of spaced slitting knives, and means for securing said knives to the under side of the first mentioned knife.
4. In a device of the character described, a 15 vegetable slicing knife comprising a, slicing knife blade having a vegetable penetrating screw and knife tilting means at one end, a finger loop at the other end, and a plurality of spaced slitting knives extending from the slicing knife blade to 4 slit the spiral cut by the operation of the slicing knife into a pluralit of strips.
