     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 9 thereof, a new and improved archery bow arrow rest apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 1 will be described. 
     More specifically, the archery bow arrow rest apparatus 1 of the instant invention essentially comprises cooperation with an archery bow 10 having an archery bow handle 11, wherein a mounting plate 12 is mounted to the archery bow in adjacency to the handle extending orthogonally relative to the archery bow between the archery bow and associated bow string (not shown). A support head 13 is fixedly mounted to the mounting plate 12, with the support head having a support plate 14 integral with and extending orthogonally relative to the support head and in an orthogonal relationship relative to the mounting plate 12, with the support plate 14 having a support plate opening 15. An arrow shield 16 extends from the support plate 14 for shielding relative to an arrow, as indicated in FIG. 2, mounted upon the apparatus. A support head boss 17 extends below the support plate 14 that is integral with the support head 13, with the support head boss 17 rotatably mounting a rotary shaft 18 orthogonally therethrough, with the rotary shaft 18 oriented below and parallel the support plate 14 extending below the opening 15. Respective first and second collars 19 and 20 mounted to the rotary shaft 18 are positioned on opposed sides of the support head boss 17 to position the rotary shaft 18 relative to the support head boss 17. A guide block 21 is provided receiving the rotary shaft 18 therethrough, with the guide block including a shaft receiving bore 22 to receive the rotary shaft 18, with a shaft fastener 23 directed through the guide block bottom wall 24 to engage the rotary shaft 18 within the shaft receiving bore 22 to permit selective adjustment and positioning of the guide block 21 relative to the support plate 14 and the associated plate opening 15. 
     Reference to FIG. 3 indicates a return spring 25 having its first end mounted to the first collar 19 and its second end mounted to the support plate 14 to bias and maintain the guide block 21 in a substantially orthogonal orientation relative to the support plate 14 permitting its deflection in a rotary manner upon guidance of an arrow relative to the guide block 21. The guide block 21 includes a guide block base 47, wherein the guide block base 47 includes respective first and second plates 26 and 27 arranged in a parallel coextensive relationship relative to one another defining a gap 28 therebetween. The first plate 26 includes a first plate canted top wall 29, with the second plate including a second plate canted top wall 30 defining an obtuse included angle between the first and second plate canted top walls 29 and 30 respectively to accommodate an arrow thereon. Respective first and second polymeric bore TEFLON inserts 31 and 33 are mounted to respective first and second plates 26 and 27. The first insert 31 is mounted and received within the first insert through the canted top wall 29 at an intersection of the canted top wall and the first plate interior wall 32. A second plate interior wall 34 arranged in a facing mirror image relationship relative to the first plate interior wall is such that the second plate interior wall 34 and the second plate canted top wall 30 form an intersection to receive the second insert 33. The insert construction, as indicated in FIG. 5 of a generally T-shaped configuration, received within the a T-shaped slot relative to the first and second plates, as indicated in FIG. 4 for example. 
     The FIGS. 6 and 7 indicates the use of a modified guide block 21a, having the first plate 26 including a T-shaped slot 46 (see FIG. 8) slidable along a T-shaped projection 46a mounted to the guide block base 47. In this manner, variation of the gap 28 is available in support of arrows of varying diameters. A threaded adjuster rod 35 extends orthogonally through the first and second plates 26 and 27, wherein the adjuster rod 35 has its first end rotatably and fixedly oriented within the first plate and threadedly directed through a threaded adjuster rod 35, whereupon rotation of the adjuster rod permits displacement of the first plate relative to the second plate in an adjustable relationship. 
     The FIGS. 8 and 9 further includes a further modified guide block 21b, to include first and second indicator lights 37 and 38. The first indicator light 37 is positioned in adjacency to the first plate canted top wall, wherein the indicator light is positioned substantially medially adjacent the first plate interior wall 32. A first battery 39 mounted within the first plate is operative through a first switch to effect illumination of the first and second indicator lights 37 and 38. A second switch 41 operative through a second battery 42 mounted in the second plate effects selective actuation of respective third, fourth, and fifth indicator lights 43, 44, and 45. The third indicator light 43 is positioned in adjacency to the second plate canted top wall spaced an equal distance relative to the guide block base 47 as the first indicator light 47. Further, the fourth indicator light 44 is spaced medially and in adjacency to the second plate interior wall 34 at a further equal spacing as the second indicator light 38, with the fifth indicator light 45 positioned into the guide block base 47 below and medially of the first and second interior walls 32 and 34. In this manner, during evening and during periods of diminished available light, the first through fifth indicator lights may be employed for the positioning of an arrow on the guide block to properly orient the guide block and arrow for release relative to a target. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall 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.
