Patented Feb. 6, 1 951 CORER William S. Hawley, Miami, Fla.
Original application A Divided an 661,798. 25, 1947, Serial No.
The present invention relates to corers for vegetables and fruit, the same being a division of my'copending application Serial No. 661,798, filed April 12, 1946, for a Culinary Utensil.
An important object of the invention is to provide a vegetable and fruit corer whereby cores can be cut in a much cleaner and convenient manner than is now possible with many of the conventional devices now being marketed.
Another object of r the invention is to provide a corer formed from a single piece of sheet metal and capable of being retailed for a nominal amount in five and ten cent stores and other stores handling low priced hardware.
These and various other objects and ad'- vantages of the invention will become apparent to the reader of the following description.
Figure 1 is a perspective view of the underside of the utensil;
Figure 2 is a perspective view of the upperside thereof;
Figure 3 is a longitudinal sectional view of the utensil taken along a plane as indicated by the line 3-3 of Figure 2; and
Figures 4 and 5 are cross sectional views of the utensil taken along planes as indicated by the lines 44 and 55, respectively, of Figure 2.
,1 Referring more particularly to the drawing, 6 designates generally the utensil in its entirety which is formed from a single elongated strip of relatively heavy gauge metal which is capable of being sharpened to form cutting edges, for a reason which will hereinafter become apparent.
The strip 6 is bowed transversely throughout its length so that the underside 1 thereof, as seen in Figure 1 is concave and the upperside 8, as seen in Figure 2, is convex. The intermediate portion!) of the strip 6, which forms the handle thereof, is wider than the end portion of the strip 5 and the side edges thereof are rolled inwardly and toward the upper surface 8 to form the rolled edges [0 which contact or substantially contact the upper surface 8 and which are adapted to be grasped by the user. One end ll of the strip 6 is tapered from the handle 9 to its extremity l2 which is rounded and sharpened. Said end II is preferably curved or bowed transversely to a greater extent than the remainder of the utensil 6, as indicated in Figure 5, and its tapered longitudinal edges l3 are sharpened throughout their lengths.
The intermediate portion of the handle 9, that is adjacent the tapered end I l, is transversely slit and the edge thereof, nearest the end I I, is bent downwardly, as best seen in Figure 3, to form a d this application August 770,483
1 Claim. (Cl. 30-25) peeling blade M the edge l5, of which, is sharpened on its upperside. The opposite end l6 of the strip 6 is relatively wide throughout its length and the side edge portions l1 thereof are preferably curved downwardly to a greater degree than its intermediate portion and protrudes below the rolled side edges ll] of the-handle 9, as seen in Figure 4. The end [-6, adjacent its extremity, is also transversely slit and the edge of said slit, remote to the handle 9, is bent downwardly to form a blade l8, as best seen in Figure 3, the edge of which is sharpened on its upperside as seen at l9.
From the foregoing it will be readily apparent that the tapered, transversely curved blade II is particularly constructed to function as a corer for removing the cores from apples, oranges, grapefruit and the like; The rounded sharpened end 12 will readily penetrate fruit and the cross sectional shape of the blade II will cause the blade to fit partially around the core after full penetration of the blade into the core has been effected. The utensil 6 can then be turned in either direction on its longitudinal axis to cause one or the other of the cutting edges [3 to sever the core from the remainder of the fruit after which the core can be withdrawn with the blade I l. The cutting edges I3 of the blade I l are also intended for use in scraping vegetables such as carrots. The blade M which is'narrower than the blade I8 provides a peeling blade for small vegetables and is spaced the proper'distance from the plane of the remainder of the intermediate portion of the handle to gauge the blade for peeling to the proper depth. A convex curvature of the handle portion is arranged to closely conform to the normal curvature of small vegetables to increase the utility of the blade 14. The wider blade [8 is constructed for peeling larger vegetables and is also spaced sufliciently from the remainder of the end Hi to properly gauge the depth that the blade l8 will cut into avegetable which is in contact with the concave surface of the end I6. The width and curvature of the end l6 is arranged to cause it to form as nearly as possible to the curvature of larger vegetables, such as potatoes. In using the utensil B for any of the aforedescribed cutting operations the rolled edges in of the handle 9 is grasped by the operation and, as will be readily apparent, the utensil 6 may be grasped relatively near to whichever of the cutting edges is being utilized thus insuring more effective use of the utensil.
Various modifications and changes are contemplated and may obviously be resorted to without departing from the spirit and scope of the invention as hereinafter defined by the appended claim.
I claim as my invention:
A culinary utensil formed from a single elongated strip of metal having one end forming a coring blade, said strip being bowed transversely from end to end thereof, the side edges of the end forming the coring blade being tapered to and terminating in a rounded extremity, said tapered edges and extremity being sharpened, the portion of the strip extending from the inner, enlarged end of the blade being wider than the blade and having rolled side edges forming reverse bends extending away from the concave side of the strip and forming a handle.
WILLIAM S. HAWLEY.
