Archery Bows and Archery Bow Components

Abstract

Compound bows and cross bows with flexible bow limbs and novel bottom (or power) cams which have reduced lean and wobble during the end part of bow draw, thereby reducing noise and vibration as an arrow is shot from the bow and contributing to the accuracy of the bows in which they are installed.

The invention claimed is: 
     
         1 . A hybrid compound bow neutral cam system comprising:
 a hybrid archery bow with a riser, a first limb and a second limb both operably attached to the riser;   a first cam rotatably attached to the first limb and a second cam rotatably attached to the second limb;   the second cam comprising:
 a center bow string guide track; 
 a first control cable guide track on a first side of the center bow string guide track and a second control cable guide track on a second side of the center bow string guide track; 
 a first buss cable guide track on a first side of the center bow string guide track and a second buss cable guide track on a second side of the center bow string guide track; 
   
       an archery bow string attached at a first end to the first cam and at a second end routed in the center bow string guide track and secured at a second end to the second cam; 
       a control cable attached at a first end to the first cam and at a second end, split into a first control cable portion and a second control cable portion, the first control cable portion routed in the first control cable guide track and secured to the second cam and the second control cable portion routed in the second control cable guide track and secured to the second cam; and 
       a buss cable attached at a first end to the first cam and at a second end, split into a first buss cable portion and a second buss cable portion, the first buss cable portion routed in the first buss cable guide track and secured to the second cam and the second buss cable portion routed in the second buss cable guide track and secured to the second cam. 
     
     
         2 . A hybrid compound bow neutral cam system as recited in  claim 1  and further comprising:
 a guide rod mounted to a lower portion of the riser, 
 a buss cable guide mounted to the guide rod positioned between the first buss cable portion and a second buss cable portion; and 
 a control cable guide mounted to the guide rod positioned between the first control cable portion and the second control cable portion. 
 
     
     
         3 . An archery bow with a hybrid cam system which comprises:
 an elongated, rigid riser; upper and lower, flexible bow limb components pivotably anchored at leading ends thereof to opposite ends of the rigid riser;   upper and lower cams rotatably supported from trailing ends of the upper and lower bow limb components; a bow string strung between the upper and lower cams; a fulcrum about which an associated one of the bow limb components is bent; the fulcrum contacting the limb component at a location between the leading and trailing ends of the limb component; and the bow further comprising:   an operator-rotatable poundage adjuster cam having bow-contacting, poundage setting determining segments or elements at different predetermined distances from the axis of rotation of the cam for setting the bend in the limb component and thereby determining the poundage of the bow;   the lower cam comprising:
 a center bow string guide track; 
 a first control cable guide track on a first side of the center bow string guide track and a second control cable guide track on a second side of the center bow string guide track; 
 a first buss cable guide track on a first side of the center bow string guide track and a second buss cable guide track on a second side of the center bow string guide track; 
 the bow string attached at a first end to the first cam and at a second end routed in the center bow string guide track and secured at a second end to the second cam; 
 a control cable attached at a first end to the first cam and at a second end, split into a first control cable portion and a second control cable portion, the first control cable portion routed in the first control cable guide track and secured to the second cam and the second control cable portion routed in the second control cable guide track and secured to the second cam; and 
   a buss cable attached at a first end to the first cam and at a second end, split into a first buss cable portion and a second buss cable portion, the first buss cable portion routed in the first buss cable guide track and secured to the second cam and the second buss cable portion routed in the second buss cable guide track and secured to the second cam.   
     
     
         4 . An archery bow with a hybrid cam system as recited in  claim 3  and further comprising:
 a guide rod mounted to a lower portion of the riser, 
 a buss cable guide mounted to the guide rod positioned between the first buss cable portion and a second buss cable portion; and 
 a control cable guide mounted to the guide rod positioned between the first control cable portion and the second control cable portion. 
 
     
     
         5 . An archery bow with a hybrid cam system as recited in  claim 4  in which the fulcrum is the poundage adjuster cam 
     
     
         6 . An archery bow with a hybrid cam system as recited in  claim 4  in which the poundage adjuster comprises a cam component actuatable by an operator to displace the leading end of the bow limb component.
