Abstract
Tip retainer mechanisms are designed primarily to secure a tip to an adapter nose for use in a variety of applications. In applications where a spring retainer is located in a recess of the adapter nose and trapped in the recess by the assembly of the tip thereon, it is necessary for the spring retainer to be properly positioned in the recess to enable easy insertion of the pin through the respective holes in the tip, adapter nose, and spring retainer. In the subject arrangement, the holder substantially encircles the outer diameter of a spring retainer. When assembled, the holder and spring retainer are placed in a recess of the adapter nose and a bore of the spring retainer is substantially axially aligned with a transverse bore of the adapter nose. Furthermore, the holder is made of an elastomeric material and has a thickness greater than a depth of the recess. Consequently, upon assembly of the tip on the adapter nose, the pin may be easily inserted through the respective holes of the tip, the transverse bore of the adapter nose, and the properly aligned bore of the spring retainer. Due to the compressive forces of the elastomeric holder, the tip is snugly held against the adapter nose to substantially eliminate the vibrations between the tip and the adapter nose.
