Cutlery implement including spring biased adjustable clamping jaws for holding food items
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to cutlery implements, and more particularly pertains to a food grasping tong designed specifically for use in handling and eating barbecued ribs. Barbecued ribs are typically served covered with a barbecue sauce which is somewhat sticky and messy to handle. Conventionally, these ribs are manually grasped in the fingers of the consumer during eating. In order to provide a neater method of eating these flavorful but messy ribs, the present invention provides a specially designed food grasping tongs for grasping and manipulating a barbecued rib while it is being eaten. 
     2. Description of the Prior Art 
     Various types of cutlery implements for grasping food items during eating are known in the prior art. A typical example of such a cutlery implement is to be found in U.S. Pat. No. 1,539,669, which issued to E. Hauser on May 26, 1925. This patent discloses a pair of insertion forks having manual grasping handle portions and which are adapted for insertion into opposite ends of an ear of corn. U.S. Pat. No. 2,999,713, which issued to J. Jones on Sept. 12, 1961, discloses a corn ear grasping implement having a wire frame with spring biased pivotal opposed grasping jaws. U.S. Pat. No. 3,794,368, which issued to J. Majeske on Feb. 26, 1974, discloses a cork screw tYpe insertion implement for use in eating an ear of corn. U.S. Pat. No. 3,805,384, which issued to A. Falcone on Apr. 23, 1974, discloses a hand manipulated tool for grasping and removing kernels from an ear of corn. U.S. Pat. No. 3,995,902, which issued to B. Sciaino, Jr. on Dec. 7, 1976, discloses a pair of insertion spikes for insertion into opposite ends of an ear of corn which are receivable in telescoping relation during storage. 
     While the above mentioned devices are directed to cutlery implements for grasping food items, none of these devices disclose a food grasping tongs having a spring steel wire frame with crossing frame members forming opposite ends of a torsional coil spring and having juxtaposed clamping jaws. Additionally, none of the aforesaid devices disclose a food grasping tongs with clamping jaws having an adjustable separation and provided with friction enhancing projections. Inasmuch as the art is relatively crowded with respect to these various types of cutlery implements, it can be appreciated that there is a continuing need for and interest in improvements to such cutlery implements, and in this respect, the present invention addresses this need and interest.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved cutlery implement embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the first embodiment 10 of the invention includes a frame formed from spring steel wire, preferably fourteen gauge type 304 stainless, which is bent into the illustrated approximately FIG. 8 configuration. The frame includes a torsional coil spring portion 20 having opposite ends forming frame members 12 and 14. The frame members 12 and 14 cross in overlying relation and have free end portions 22 and 24 provided with respective grasping jaws 26 and 28. The juxtaposed grasping jaws 26 and 28 have facing grasping surfaces which are formed by metal plates bent into a slightly concave curvature, as shown. Plastic circular handle portions 16 and 18 are formed on the frame members 12 and 14 to facilitate manual manipulation of the cutlery implement and to allow the grasping jaws 26 and 28 to be manually moved to an open position. The torsional coil spring 20 provides a spring bias which maintains the grasping jaws 26 and 28 in the illustrated closed position. 
     FIG. 2 is a side view which further illustrates the construction of the cutlery implement 10 of FIG. 1. 
     As shown in FIG. 3, a food item, such as a barbecued rib R, may be held between the jaws 26 and 28 during consumption. The handles 16 and 18 are preferably formed from a dishwasher safe plastic material to enable convenient cleaning of the cutlery implement 10 after use. As may now be understood, the cutlery implement 10 permits ordinarily messy barbecued ribs R to be consumed without soiling the fingers and hands of the consuming individual. 
     FIG. 4 is illustrates a slightly modified second embodiment 10&#39; of the present invention, formed identically as illustrated and described with reference to FIGS. 1 through 3, with the exception of the grasping jaws 26&#39; and 28&#39;. The grasping jaws 26&#39; and 28&#39; are each formed from a planar disk provided with respective pointed projections 30 and 32 for frictional engagement with a food item. A cylindrical centrallY threaded sleeve 34 and 38 is centrally secured to an outer face of each of the jaws 26&#39; and 28&#39; and is utilized to form an adjustable threaded connection with the respective end portions 22 and 24 of the wire frame. Position locking nuts 36 and 40 are utilized to secure the clamping jaws 26&#39; and 28&#39; in a selected adjusted position. 
     FIG. 5 is a detail view, partially in cross section, which illustrates the internally threaded blind bore 39 of the sleeve 38 together with the threaded bore 41 of the lock nut 40. As shown, the distal end portion 25 of the frame member 24 is threaded, to allow engagement with the lock nut 40 and sleeve 38. As may now be understood, the separation of the clamping jaws 26&#39; and 28&#39; may be adjusted by virtue of these threaded connections. The spring steel wire frame is preferably configured to provide abutting engagement between the jaws 26&#39; and 28&#39;, when both of the jaws are adjusted for minimum separation. Thus, when the jaws are configured for a greater separation, they will be slightly spaced when biased to their fully closed position. By appropriate adjustment, the cutlery implement 10&#39; may be utilized with a wide variety of different dimensioned food items, and may be particularly adjusted for use in grasping short ribs by both opposite ends thereof, or for use in grasping only one end. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
