Pipe cutter
First Claim
1. A pipe cutter for cutting a pipe, the pipe cutter comprising:
- a cutting head assembly including a first carriage and a second carriage spaced apart to define a cutting area, the first carriage having a first portion supporting a cutting mechanism and the second carriage configured to support a pipe within the cutting area, wherein the carriages have a locked state and an unlocked state, andfurther wherein when the carriages are in the unlocked state, the carriages are movable relative to each other and biased into the cutting area;
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 a second portion of the first carriage in a locked state relative to the second carriage, the locking mechanism comprising,an actuation member rotatably coupled to the second portion of the first carriage, wherein rotation of the cutting head assembly causes rotation of the actuation member relative to the first carriage, anda locking member configured for engagement with the first carriage and the second carriage upon rotation of the actuation member, wherein engagement of the locking member with the first carriage and the second carriage holds the carriages in the locked state,wherein the first carriage includes a biasing member between the first portion and the second portion, wherein upon rotation of the cutting head assembly the actuation member rotates relative to the first carriage and deflects the biasing member such that a biasing force acts on the cutting mechanism to cut the pipe.

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.

21. A pipe cutter for cutting a pipe, the pipe cutter comprising:
a cutting head assembly including, a first carriage including a biasing arm having a first portion with a cutting mechanism, and having a second portion, a second carriage spaced apart from the first carriage to define a cutting area, the second carriage including a support surface for supporting a pipe within the cutting area, an over-center position for the pipe, the over-center position defined by the cutting mechanism and the support surface, wherein the carriages have an unlocked state for inserting the pipe into the cutting area and a locked state for cutting the pipe, wherein when the first carriage is in the unlocked state the first carriage is movable relative to the second carriage and is biased into the cutting area, and a spring biasing the second carriage into the cutting area such that when the second carriage is in the unlocked state, the second carriage is movable relative to the first carriage; a drive assembly configured to rotate the cutting head assembly; and a locking mechanism configured for moving the carriages from the unlocked state to the locked state and for holding the carriages in the locked state when the pipe is positioned in the over-center position, the locking mechanism comprising, an actuation member rotatably coupled to the second portion of the first carriage, wherein rotation of the cutting head assembly causes rotation of the actuation member relative to the first carriage, and a locking member configured for engagement with the second portion of the first carriage and the second carriage upon rotation of the actuation member, wherein engagement of the locking member locks the second portion of the first carriage and the second carriage together and deflects the biasing arm such that a biasing force acts on the cutting mechanism to cut the pipe. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
