With reference now to the drawings, and in particular to FIGS. 1 to 10 thereof, a new and improved archery bow sighting apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

More specifically, the archery bow sighting apparatus 10 of the invention essentially comprises a framework defined by a plurality of front legs 11 spaced from and parallel a plurality of rear legs 12. A horizontal support beam 13 is mounted orthogonally between the front and rear legs 11 and 12, with a front and rear vertical post 14 and 15 respectively mounted medially to the lower horizontal support beam 13 in a coplanar relationship relative to the respective front and rear legs 11 and 12. Each of the front and rear vertical posts 14 and 15 respectively include a respective front and rear telescoping leg 16 and 17 mounted therewithin, A lock rod 17a is orthogonally directed through each vertical post to effect vertical positioning of each telescoping leg within a respective post. A top horizontal support beam 18 is orthogonally mounted to each upper terminal end of the respective front and rear telescoping legs 16 and 17 to permit vertical adjustment of the top horizontal support beam 18 to accommodate individual archery shooters to permit their sighting along the top horizontal support beam 18. The top horizontal support beam 18 mounts a respective right guide rail 19 and a left guide rail 20 in parallel relatioship relative to one another and on opposed longitudinal sides of the top horizontal support beam 18, in a manner as illustrated in FIGS. 8, 9, and 10. A central drive screw 21 is positioned medially of and parallel to the right and left guide rails 19 and 20 and is threadedly directed through a bow string retraction member 23. Retraction member 23, as illustrated in FIG. 3 for example, utilizes a tensioning block 22 receiving the right guide rail 19, the left guide rail 20, and the central drive screw 21 therethrough. The retraction member 23 includes a string release member 24 for securement and retraction of the associated bow string therewithin. FIG. 9 illustrates a modified bow string retraction member 23a that includes a retraction member vertical plate 25 orthogonally mounted to a retraction member lower horizontal support plate 26 that is fixedly mounted to a top surface of the tensioning block 22. A retraction member upper horizontal support plate 27 is spaced above and parallel the lower horizontal support plate 26, and includes a receiving slot 28 to receive the low bow string therewithin. An adjusting slot and lock screw 29 and 29a respectively permit lateral displacement of the retraction member vertical plate 25 relative to the retraction member lower horizontal plate 26, as illustrated in FIG. 9. A peep sight vertical support plate 30 mounted parallel to and above the vertical plate 25 includes a support blade slot 31 positioned medially thereof to adjustably mount a peep sight member 32 therewithin that is directed laterally of the slot 31 for sighting of the arrow "A" relative to the associated bow structure "B" upon release of the arrow relative to the bow "B" as illustrated in FIG. 10. A release pin 33 directed releasably into the upper horizontal support plate 27 maintains the bow string "S" within the slot 28 prior to retraction of the pin 33 relative to the slot.

A plumb bob and support line 34 (see FIG. 10) are sighted along a setting line 34a to intersect upper and lower terminal ends of the bow "B". To permit vertical adjustment and positioning in alignment of the sighting line 34a, a bow mounting plate 35 includes (see FIGS. 5, 6, and 10) mounting "U" bolt 39 orthogonally directed through the mounting plate 35 to secure the bow "B" to the mounting plate. A mounting "U" bolt springs 40 positioned between the mounting plate 35 and the bow "B" effect tensioning of the bow "B" in relative position to the mounting plate, as illustrated in FIGS. 5 and 6. An adjusting rod 41 positioned below and medially between the mounting "U" bolt legs of the mounting "U" bolt 39 is threadedly directed through the mounting plate 35 and includes a rear terminal end impinging upon the bow "B" to effect rotation of the bow "B" upon the mounting "U" bolt 39 and thereby effects adjustment and vertically positioning of the bow "B" along the setting line 34a.

In retraction of the bow string "S", by the retraction member 23 as illustrated in FIG. 9 for example, a bow string gauge block 36 is positioned and received on the top surface of each respective right guide rail 19, left guide rail 20, and central drive screw 21 by the block 36 that includes a plurality of arcuate recesses 37 that are spaced apart a predetermined spacing substantially equal to a predetermined spacing defined between the respective right guide rail 19, left guide rail 20, and central drive screw 21 (see FIGS. 5 and 5a). A gauge block rod 38 projects orthogonally relative to the right and left guide rails 19 and 20 to provide positioning of the bow string retraction relative to the bow "B", as illustrated in FIG. 5.

Alternative devices are utilized to effect retraction of the bow string such as a pneumatic cylinder 46 (see FIG. 8) utilizing a support plate 47 mounting the pneumatic cylinder, or alternatively the use of a motorized gear drive 48 to effect selective rotation of the central drive screw 21. If desired, the central drive screw 21 may further utilize (see FIG. 7) a drive wheel 49 orthogonally mounted to a rear terminal end of the drive screw projecting exteriorly of the gear drive 48. Further, as illustrated in FIG. 7, a telescoping leg drive front rod 50 is mounted to each lower terminal end of each of the front and rear telescoping legs 16 and 17 to effect selective adjustment of each leg relative to the respective front and rear vertical posts 14 and 15.
