the cable 40 b causes the actuator link 160 to pull on the actuator arm 185 this in turn causes movement of the pinion gear or toothed wheel 152 movement of the gear 152 against the rack 200 in the rotating slide plate 195 causes the guide pins 180 to move along the guide cam slots 190 as the guide pins 180 move along the guide cam slots 190 to the position shown in fig5 a the support fingers 120 are simultaneously forced inward toward the central axis 113 encompassing trapping holding and containing the arrow 40 about 360 degrees of the circumference of the arrow shaft once the bowstring has been drawn back to full draw the orientation of the bow can be changed from vertical to horizontal without any risk of the arrow falling out of the rest when the archer releases the bowstring 40 the actuator link 160 loses its tension against the actuator arm 185 the spring 170 then causes the gear 152 to rapidly rotate the rotating slide plate 195 in the opposite direction causing the guide pins 180 to move back along the guide cam slots 190 and outwardly from the arrow the support fingers 120 then fully retract allowing passage of the arrow shaft and fletching without interference the spring 170 prevents any recoil in the mechanism from causing the support fingers to rebound into the path of the arrow unless otherwise defined all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs although methods and materials similar to or equivalent to those described herein can be used in the.
