     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved survey apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the survey apparatus 10 of the instant invention essentially comprises a first table assembly 11 cooperative with a second table assembly 12 to provide for alignment between the tables in a range finding and alignment orientation relative to one another. To this end, the first table assembly 11 includes a first table first plate 13 pivotally mounted to a first table second plate 14 about a first axle is, with a second table first plate 16 pivotally mounted relative to a second table second plate 17 about a second axle 15a (see FIG. 3). A first axle leg 18 is mounted in parallel adjacency relative to the first axle 15, with a second axle leg 19 mounted in parallel adjacency relative to the second axle 15a, such that first legs 20 are orthogonally mounted to the first table first plate 13, with second legs 21 orthogonally mounted to the first table second plate 14. Threaded legs 22 are orthogonally mounted to the second table first plate 16, with fourth legs 23 orthogonally mounted to the second table second plate 17. As the first table first plate and the second table first plate 13 and 16 respectively are arranged for alignment relative to one another, and are to be leveled employing respective first and second spirit levels 29 and 29a (see FIGS. 2 and 3 respectively), the first through fourth legs may be provided with adjustment of various types such as telescoping, threaded inter-engagement, and the like, in a manner known in the prior art and believed to be available in the prior art to one requiring such adjusting ability. Further, the first table first plate 13 and the second table first plate 16 are provided respectively with first and second compass members 28 and 28a respectively, as illustrated in FIGS. 2 and 3 respectively. A sighting scope 24 is mounted to the first table first plate 13, with a sighting scope 24 mounted in longitudinal alignment on the first table first plate for sighting through the first sight tube, that includes the sight tube orthogonally intersecting cross hairs 32 to assist in alignment, with a second sight tube 26 mounted to the second table first plate for alignment with a third sight tube 27. The second sight tube 26 includes second tube guide indicia 31 oriented within the second sight tube at ninety degree intervals, with the third sight tube 27 including a third tube mirror end wall 33 having orthogonally intersecting third tube cross hairs 34, such as indicated in the FIG. 3b. In this manner, longitudinal alignment of the sighting scope 24 is directed for aligning the first table first plate with the second table first plate. It should be noted that the sighting scope 24 is arranged for pivotal mounting orthogonally relative about a sight scope support shaft 24a that in turn is pivotally mounted orthogonally relative to the first table first plate. A digital range finder 35 may be optionally employed by the sighting scope, in a manner as indicated in FIG. 4, of a type as exemplified in the U.S. Pat. No. 4,531,833 incorporated herein by reference. To this end, a laser emitter housing 37 is mounted to the sighting scope (see FIG. 6) directing a laser beam 38 that is arranged to effect alignment with a guide plate 39 mounted to the second plate tube 26, with the guide plate 39 having a guide plate aperture 40 to provide visible alignment with a target plate 41, that in turn is mounted to the third sight tube 27. The target plate 41 includes target plate cross hair intersection 42 to receive the laser beam 38 to further enhance alignment of the first table first plate with the second table first plate. The first table second plate 4 and the second table second plate 17 are provided with respective first and second arcuate scales 30 and 30a respectively that are concentric with the respective first and second axles 15 and 15a respectively to provide for measuring angular orientation of the first table second plate and the second table second plate relative to the respective first table first plate and the second table first plate in measuring angular orientations within a room and the like when directing orthogonal angulations. If desired, a digital indicator member 43 may be mounted relative to the first table first plate and the second table first plate for providing visual indication of angular measurement with respective tail plates within a respective table assembly. 
     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 tile 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.
