Crescent wrench

An adjustable wrench comprising:

• a main body, said main body including an elongate handle portion and a head portion,
• said head portion including a fixed primary jaw, said primary jaw including a fixed grasping face having a distal segment and a proximal segment,
• said head portion further including a pair of spaced parallel track segments extending from said proximal segment of said fixed grasping face, said track segments each including an upper slide face and defining a central channel therebetween,
• a sliding secondary jaw, said secondary jaw including a sliding grasping face having an upper segment and a lower segment, said lower segment being substantially narrower than said upper segment such that said lower segment is slidably disposed between said track segments,
• said sliding secondary jaw further including an elongate gear member extending tangentially from said lower segment of said sliding grasping face and being axially and slidingly disposed within said central channel such that sliding of said gear member within said channel results in corresponding sliding of said secondary jaw along said track segment, thereby positioning said sliding secondary jaw a desired distance from said fixed primary jaw,
• said gear member including a plurality of gear teeth,
• a worm gear disposed within said head portion, said worm gear being structured and disposed to engage said gear teeth on said gear member such that rotation of said worm gear results in corresponding axial movement of said gear member within said central channel,
• said wider upper segment of said sliding grasping face including a pair of parallel jaw slide faces disposed on opposite sides of said lower segment of said sliding grasping face, said jaw slide faces slidingly and matingly confronting said upper slide faces of said parallel track segments,
• a vertical bore extending through at least one of said jaw slide faces into said sliding secondary jaw,
• a vertical spring disposed within said vertical bore,
• a plurality of spaced recesses disposed along a corresponding one of said upper slide faces of said parallel track segments, said recesses being spaced predetermined distances from one another, and
• a ballbearing disposed between said vertical spring and said corresponding one of said upper slide faces of said parallel track segments, said spring exerting an outwardly biasing force on said ballbearing such that upon positioning of said vertical bore atop one of said spaced recesses, said ballbearing is urged partially into said one recess thereby resulting in removable locked engagement of said ballbearing within said one recess and a substantially audible sound being made so as to signal locked engagement at one of said plurality of recesses.
