Archery Bow with Limb Spacing Adjustment

Abstract

In some embodiments, an archery bow comprises a limb assembly comprising a first limb and a second limb, the second limb comprising limb threads. An axle assembly is supported by the first limb and the second limb. The axle assembly comprises an axle comprising axle threads. A first connection between the axle assembly and the first limb comprises a fixed connection. A second connection between the axle assembly and the second limb comprises the limb threads engaged with the axle threads. Rotation of the axle with respect to the limb assembly adjusts a distance between the first limb and the second limb.

1 . An archery bow comprising:
 a limb assembly comprising a first limb and a second limb; the second limb comprising limb threads;   an axle assembly supported by the first limb and the second limb, the axle assembly comprising an axle comprising axle threads;   a first connection between the axle assembly and the first limb, the first connection comprising a fixed connection; and   a second connection between the axle assembly and the second limb, the second connection comprising the limb threads engaged with the axle threads;   wherein rotation of the axle with respect to the limb assembly adjusts a distance between the first limb and the second limb.   
     
     
         2 . The archery bow of  claim 1 , wherein the first connection excludes helical threads oriented between the first limb and the axle. 
     
     
         3 . The archery bow of  claim 1 , wherein rotation of the axle with respect to the limb assembly moves the second limb along a length of the axle but does not move the first limb along the length of the axle. 
     
     
         4 . The archery bow of  claim 1 , the axle assembly comprising a fastener assembly attached to the axle, the fastener assembly abutting the first limb. 
     
     
         5 . The archery bow of  claim 4 , the fastener assembly comprising a fastener and a washer, the fastener engaging the axle, the washer abutting the first limb. 
     
     
         6 . The archery bow of  claim 1 , the second connection comprising a locking mechanism arranged to prevent the axle from rotating with respect to the second limb. 
     
     
         7 . The archery bow of  claim 6 , the locking mechanism comprising a fastener arranged to apply a force between the axle and the second limb. 
     
     
         8 . The archery bow of  claim 1 , the axle comprising a flange arranged to locate a rotatable member. 
     
     
         9 . The archery bow of  claim 8 , comprising a roller bearing in contact with the flange. 
     
     
         10 . The archery bow of  claim 9 , comprising a spacer surrounding the axle, the spacer abutting the roller bearing, the spacer in compression along its length. 
     
     
         11 . The archery bow of  claim 1 , the first limb comprising a first bracket, the axle assembly abutting the first bracket. 
     
     
         12 . The archery bow of  claim 11 , the second limb comprising a second bracket, the second bracket comprising the limb threads. 
     
     
         13 . The archery bow of  claim 12 , the axle comprising a marking, the marking visible through a window in the second bracket. 
     
     
         14 . An archery bow comprising:
 a first limb comprising a first bracket;   a second limb comprising a second bracket, the second bracket comprising bracket threads;   an axle comprising a first portion and a second portion, the first portion attached to the first bracket, the second portion comprising axle threads engaged with the bracket threads;   wherein rotation of the axle with respect to the second bracket adjusts a distance between the first bracket and the second bracket.   
     
     
         15 . The device of  claim 14 , further comprising a rotatable member supported by the axle. 
     
     
         16 . The device of  claim 15 , wherein the axle comprises a flange, the rotatable member abutting the flange. 
     
     
         17 . The device of  claim 14 , further comprising a bearing oriented between the first bracket and the axle. 
     
     
         18 . The device of  claim 17 , wherein the rotatable member contacts the bearing. 
     
     
         19 . The device of  claim 14 , further comprising a fastener attached to the axle. 
     
     
         20 . The device of  claim 14 , wherein the axle comprises a marking, the marking visible through a window in the second bracket.
