Archery Bow String Suppressor With Adjustable Spring Tension

Abstract

An archery bow string suppression device with adjustable spring tension and isolated free floating transfer rod designed to be used to dampen the shock and vibration normally associated with firing a bow or crossbow.

1 . An archery bow string suppressor adapted to be removably attached to a fitting or hole on an archery bow or cross bow, said string suppressor comprising:
 a shaft having a cushion member of vibration damping material mounted on a first end for contacting a bow string and dampening string vibrations,   a body having a chamber within which a second end of said shaft is located;   a mounting bolt having a head which may be surrounded by an O ring located at or near one end of said chamber; and   a spring located in said chamber having an end which may be seated on an O ring around the head of the mounting bolt and another end resting on an adjustable internal bushing.   
   
   
       2 . The archery bow string suppressor of  claim 1  wherein said second end of said shaft is attached to a first bushing and a second bushing located adjacent to said first bushing. 
   
   
       3 . The archery bow string suppressor of  claim 2  wherein said first and second bushings are movably attached to shaft, said shaft containing threads, etchings, grooves, or similar items designed to maintain said bushings in their desired location. 
   
   
       4 . The archery bow string suppressor of  claim 3  wherein one end of said spring seats on the first bushing. 
   
   
       5 . The archery bow string suppressor of  claim 4  wherein said spring may or may not be compressed. 
   
   
       6 . The archery bow string suppressor of  claim 5  wherein said first and second bushings are composed of or contained vibration absorbing material such as rubber or elastomer. 
   
   
       7 . The archery bow string suppressor of  claim 6  wherein said first bushing controls spring tension and shaft travel. 
   
   
       8 . The archery bow string suppressor of  claim 7  wherein said second bushing provides adjustment of the location of the cushion member relative to the bow string when the string suppressor is attached to an archery bow or cross bow. 
   
   
       9 . The archery bow string suppressor of  claim 8  wherein a scale is located on said shaft to indicate the distance that the shaft moves when an arrow is shot. 
   
   
       10 . The archery bow string suppressor of  claim 9  wherein an O ring or similar type device is moveably coupled to the shaft to mark the distance on the scale that the shaft moves when an arrow is shot. 
   
   
       11 . The archery bow string suppressor of  claim 10  wherein said rod is isolated from said body through the use of said first and second bushings as well as additional isolation bushings mounted in said body. 
   
   
       12 . A method of stabilizing a bow string with a string suppressor adapted to be removably attached to a fitting or hole on an archery bow or cross bow, said method comprising:
 providing a shaft having a cushion member of vibration damping material mounted on a first end for contacting a bow string and dampening string vibrations,   providing a body having a chamber within which a second end of said shaft is located;   locating a mounting bolt having a head which may be surrounded by an O ring at one end of said chamber; and   placing a spring in said chamber with one end seated against the O ring or mounting cap and an opposite end seated against said adjustment bushing.   
   
   
       13 . The archery bow string suppressor of  claim 12  wherein second end of said shaft is attached to a first bushing and a second bushing located adjacent to said first bushing. 
   
   
       14 . The method of  claim 13  wherein said first and second bushings are movably attached to the shaft. 
   
   
       15 . The method of  claim 14  wherein a bushing of vibration absorbing material isolates the body from the shaft. 
   
   
       16 . The method of  claim 15  wherein said first and second bushings are composed of or contain vibration absorbing material such as rubber or other elastomers. 
   
   
       17 . The method of  claim 16  wherein said first bushing controls spring tension and shaft travel. 
   
   
       18 . The method of  claim 17  wherein said second bushing provides adjustment of the location of the cushion member relative to the bow string when the string suppressor is attached to a archery bow or cross bow. 
   
   
       19 . The archery bow string suppressor of  claim 18  wherein a scale is located on said shaft and an O ring or similar device is moveably coupled to the shaft to mark a distance on the scale that the shaft moves when an arrow is fired. 
   
   
       20 . The method of  claim 13  wherein said second bushing provides final adjustment of the location of the cushion member relative to the bow string when the string suppressor is attached to a bow; and said first bushing sets string tension to control shaft travel when an arrow is shot.
