     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new Pin Vise 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 Pin Vise 10 comprises a base member 20, a support shaft 30 secured to the cornice of the base member 20 at one end and projecting orthogonally to the base member 20, a top member 40 secured to the end of the support shaft 30 opposite of the base member 20 and parallel to the base member 20, where the top member 40 includes a cylindrical spring recess 44 at one end and a syncline notch 42 at the opposite end, and a spring loaded pin retaining means 50 slidably secured to the top member 40 thereby removably retaining various sizes of pins 12 mesial it and the top member 40 for grinding to a specified length. 
     As best illustrated in FIGS. 1 through 4, it can be shown that the spring loaded pin retaining means 50 includes an L-shaped member 52 including an aligning slot 53 along the lengthened side. There at least two aligning bolt 59s project slidably through the aligning slot 53 then secured to the top member 40 allowing the L-shaped member 52 to slide on a horizontal plane. The L-shaped member 52 includes an adjusting bolt 54 threadably engaging the end adjacent to the aligning slot 53 parallel to the aligning slot 53. The adjusting bolt 54 projects slidably through a compression spring 55 which is mesial within the spring recess 44 and the adjusting bolt 54, providing force to separate the L-shaped member 52 and the top member 40 as best disclosed in FIGS. 2 and 3 of the drawings. As best shown in FIG. 2 of the drawings, a first bolt 58 projects through a cantilever 56, then through a bushing 57, then secured to the end of the L-shaped member 52 opposite of the adjusting bolt 54 and projecting orthogonally to the longitudinal axis of said adjusting bolt 54. The cantilever 56 is pivotally secured to the first bolt 58. The cantilever&#39;s 56 end nearest the top member 40 is formed into a syncline shape which corresponds to and is received by the syncline notch 42 of the top member 40 as best shown in FIG. 2. The pin 12 is removably received mesial the syncline notch 42 and the end of the cantilever 56 syncline shaped. The top member 40 includes a diamond point 51 on the cornice for dressing the surface grinder wheel. A cuff 32 slidably surrounds the support shaft 30 mesial the base member 20 and the top member 40 as shown in FIG. 1 of the drawings. The cuff 32 is locked into position by an unnumbered tightening bolt. A support member 34 is secured to the cuff 32 opposite of the tightening bolt and projecting parallel to the top member 40 as shown in FIG. 1 and 6 of the drawings. The support member 34 supports the bottom end of the pin 12 thereby preventing said pin 12 from descending during grinding to the proper length. The top member 40 and the base member 20 are preferably each secured to the support shaft 30 by an unnumbered threaded bolt centrally positioned as shown in FIG. 5 of the drawings. A bottom dowel 36 is preferably secured within the base member 20 and the support shaft 30 thereby preventing rotation as shown in FIG. 5 of the drawings. A top dowel 38 is secured within the top member 40 and the support shaft 30 thereby preventing rotation. The components are preferably constructed from hardened steel. 
     In use, the user pulls down the end of the cantilever 56 opposite of the end which is syncline shaped. The user then positions the upper portion of the pin 12 within the syncline notch 42 and the bottom end juxtaposed to the cornice of the support member 34. The user then pivots the cantilever 56 so the longitudinal axis of the cantilever 56 is parallel to the base member 20 and where the syncline shaped end is juxtaposed to the pin 12 thereby retaining said pin 12 mesial the cantilever 56 and the top member 40. The compression spring 55 pulls the cantilever 56 towards the pin 12 so as to retain said pin 12 for grinding. The user grinds the pin 12 until the proper length has been achieved. Thereafter, the user then pivots the cantilever 56 to release the pin 12 from the present invention. The user removes the pin 12 and repeats the above procedure for a plurality of other pins 12 of various sizes. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     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.
