Abstract
A pipe cutter includes a jaw formed on one end of a handle and includes a cutter blade pivotally coupled to the handle and having a cutter edge adapted to be moved toward the jaw for cutting a pipe. The cutter blade includes a number of ratchet teeth formed in the bottom peripheral portion and includes a depression having two end portions. A handgrip includes an actuator for engaging with the ratchet teeth and for rotating the cutter blade. A pawl may prevente the cutter blade from rotating in the reverse direction. An adjusting member is pivotally coupled to the handle and includes a protrusion slidably engaging with the depression of the cutter blade and engageable with either of the end portions of the depression for adjusting the distance between the cutter edge and the jaw.
Claims7
A pipe cutter comprising:
- a body including a first end having a handle and including a second end having a jaw for engaging with a pipe to be cut,
- a cutter blade pivotally coupled to said body at a spindle and adapted to rotate in an active direction and a reverse direction, said cutter blade including a cutter edge adapted to be moved toward said jaw of said body for cutting the pipe, said cutter blade including a bottom peripheral portion having a plurality of ratchet teeth, said cutter blade including a depression having a first and a second end portions,
- a handgrip pivotally coupled to said body for allowing said handgrip to be moved toward and away from said handle, said handgrip including an actuator for engaging with said ratchet teeth of said cutter blade and for allowing said handgrip to rotate said cutter blade when said handgrip is moved toward said handle,
- means for engaging with said ratchet teeth of said cutter blade and for allowing said cutter blade to rotate in said active direction and for preventing said cutter blade to rotate in said reverse direction,
- an adjusting member pivotally coupled to said body at a pivot axle and including a protrusion for slidably engaging with said depression of said cutter blade, said protrusion being adapted to engage with either of said first and said second end portions of said depression, and
- means for maintaining said protrusion in either of said first and said second end portions of said depression,
- said cutter edge being spaced away from said jaw at a greater distance for cutting the pipe of greater diameter when said protrusion is engaged with said first end portion of said depression, and said cutter edge being spaced away from said jaw at a shorter distance when said protrusion is engaged with said second end portion of said depression for cutting the pipe of smaller diameter.
