     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 9 thereof, a new and improved bowling training apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the bowling training apparatus 10 of the instant invention essentially comprises a support shaft 11, having respective first and second support legs 12 and 13 orthogonally and integrally mounted to the support shaft 11 at opposed ends of the support shaft, wherein the first and second support legs 12 and 13 are arranged in a coextensive and parallel relationship relative to one another. The first support leg 12 includes a first support head at the free distal end of the first support leg, with the second support leg having a second support head 15 at a free distal end of the second support leg, with the first head 14 having a first head support shaft 16 orthogonally mounted fixedly to the first head 14 in an orthogonal relationship relative to the first support leg 12. The second head 15 has a second head support shaft 17 integrally mounted to the second head in an orthogonal relationship relative to the second support leg 13, wherein the first and second head support shafts 16 and 17 are mounted within respective first and second gutter channels 26 and 27 of a bowling lane 25 as the support shaft 11 spans the bowling lane between the gutter channels 26 and 27, as indicated in FIG. 2. Respective first, second, and third signal members 21, 22, and 23 respectively are slidably mounted along the support shaft 11 in a rotatable relationship, to be discussed in more detail below, with respective first, second, and third resilient ring pairs 18, 19, and 20 mounted to opposed sides of the respective first, second, and third signal members 21, 22, and 23 to effect selective positioning of the signal members along the support shaft 11. In this manner, the resilient ring pairs may be longitudinally displaced along the support shaft 11 to position a respective signal member therebetween to provide for a target orientation of the signal members relative to the bowling lane as the bowling ball 24 passes below the support shaft 11. As the bowling ball 24 effects contact with one of the signal members 21-23, the signal members are rotatably displaced along the support shaft 11 for visual indication of positioning of the bowling ball relative to the bowling lane, as indicated. Each of the signal members 21-23 includes a rotary hub 28 rotatably mounted to the support shaft 11, with the rotary hub 28 having a hub flange 29 and a shaft 30, wherein the flange and shaft are diametrically aligned relative to one another on opposed sides of an associated rotary hub 28. In this manner, the rotary hub 29 is spaced from the bowling lane 25 a predetermined spacing that is less than the predetermined diameter defined by the bowling ball 24 to effect contact with a bowling ball relative to the flange 29 to effect rotary displacement of an associated signal member, as indicated in FIG. 2. 
     With reference to FIGS. 5 and 6 indicates that each of the support legs 12 and 13 (for purposes of illustration only the second support leg 13 is described, but it should be understood that they are to be of identical construction), wherein each support leg includes a leg externally threaded end portion 32 threadedly receiving an internally threaded locking collar 33 that includes a collar annular flange 36. The collar annular flange 36 is arranged to be received within an annular groove 35 of an extension shank 34 that is coaxially aligned with the locking collar 33 and the leg 13, with the free distal end of the extension shank 34 having mounted thereon the associated second head 15. In this manner, height adjustment of the support shaft 11 is provided to accommodate varying heights of an associated gutter relative to a bowling lane 25. 
     The FIGS. 5 and 7 through 9 further indicate that each of the signal members may be arranged for interlocking relative to one another to provide for a greater target area relative to the bowling ball 24. To this end, each flange 29 includes a locking tube 37 and a locking rod 38, each pivotally mounted relative to the flange 29. A locking tube 37 is arranged to receive a locking rod 38 of an adjacent signal member 29 and in this manner, such as indicated in FIG. 9, provide for interlocking of a plurality or all of the signal members as desired to provide for the greater target area of the bowling ball as it passes beneath the support shaft 11. 
     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.
