Abstract
A drive system cooperating with the drive mechanism of a ratchet wrench enables a user to use the wrench for its intended purpose and also spin the drive at high speed by pulling an endless belt. The belt is contained in a manner which causes structures on the belt to engage with exposed gear teeth of the ratchet wrench or an attachment. The containment structure provides for proper alignment and positioning of the belt to allow for the desired engagement with the drive teeth even after the user releases grip from the belt. The containment structure further allows an opposite end of the belt to hang loose and thus be easily accessible by a user. The drive system can be used on a socket ratchet without exposed teeth by adding gear teeth to a ratchet drive member or socket either permanently, as an added part or as an extension to the socket ratchet or socket.
