  • Patent number: 10046470
    Abstract: A pipe cutter for cutting a pipe includes a cutting head assembly having a first carriage and a second carriage spaced apart to define a cutting area. The first carriage supports a cutting mechanism, and the second carriage is configured to support a pipe within the cutting area. The carriages have a locked state and an unlocked state such that when the carriages are in the unlocked state, the carriages are movable relative to each other and biased into the cutting area. The pipe cutter also includes a drive assembly configured to rotate the cutting head assembly and a locking mechanism configured for changing the carriages from the unlocked state to the locked state and for holding the carriages in the locked state. The locking mechanism includes an actuation member rotatably coupled to the first carriage.

  • Patent number: 9233427
    Abstract: A power tool includes a housing having a handle configured for a user, the handle defining a first axis, a motor supported by the housing, the motor defining a second axis along a length of the motor, a tool element movably supported by the housing and drivingly coupled to the motor, the tool element defining a third axis along a length of the tool element. Each of the first, second, and third axes are oblique with respect to each of the other axes.

  • Patent number: 8853578
    Abstract: A power tool having a paddle switch is configured to allow easier actuation of a switch mechanism. The power tool comprises a housing, a support surface disposed within the housing, a switch mechanism having a first position and a second position, a paddle member including an input surface and a hinge pin positioned a distance from the support surface, and a multiplier member pivotally connected to the hinge pin and having a first arm and a second arm. The first arm of the multiplier member extends from the hinge pin along a first longitudinal axis, and the second arm of the multiplier member extends from the hinge pin along a second longitudinal axis that is not parallel to the first longitudinal axis. The second arm is disposed to contact the support surface when force is applied to the input surface, causing rotation of the multiplier member about the hinge pin. The rotation of the hinge pin causes the first arm to contact the switch mechanism and move it from the first position to the second position.

  • Patent number: 8763257
    Abstract: A power tool, such as a pipe cutter, includes a rotatable cutting head assembly, an electric motor connectable to a rechargeable battery, and a controller. The controller is configured to monitor the state of charge on the battery, compare the state of charge to one or more thresholds, and prevent or limit operation of the power tool when the state of charge is less than or equal to one or more of the thresholds. In some embodiments, the threshold includes the state of charge required to cut a pipe, the state of charge required to return the cutting head assembly to a home position, and a state of charge indicative of an overdischarged condition of the battery. In some embodiments, the controller is configured to detect when the pipe cutter has completed cutting the pipe and returns the cutting head assembly to the home position.
