Abstract
A cutter adapted for cutting a range of different diameter plastic pipe and tubing with a pair of jaw members pivoted on a pivot pin intermediate their ends with the first of the jaw members pivoted within the second of the jaw members. The first of the jaw members having a knife blade and the second jaw member having a cradle with a cutting cage into which the knife extends. The pivot pin being longitudinally adjustable in the second jaw member for changing the pivot axis.
Claims13
A cutter adapted for cutting a range of different diameter plastic pipe and tubing into multiple separate pieces, the cutter comprising a pair of jaw members pivotally connected intermediate their ends, a pivot pin about which a first of the jaw members is pivoted within a second of the jaw members, the first jaw member having a handle at one end and a knife blade extending from the other end opposite to said handle, said knife blade having a longitudinal cutting edge, the other of said jaw members having a handle at one end and a cradle with a generally semicircular non-sharpened cutting cage at the other end into which the knife blade extends, said pivot pin being longitudinally adjustable in the second jaw member for changing the pivot axis of the first jaw member thereby changing the effective cutting cage of the cradle and the angle at which the cutting edge of the knife blade makes on initial contact with the pipe and tubing.
A cutter adapted for cutting a range of different diameter plastic pipe and tubing comprising a pair of jaw members pivotally connected intermediate their ends, a pivot pin about which a first of the jaw members is pivoted within a second of the jaw members, the first jaw member having a channel-shaped handle at one end and a knife blade extending from the other end opposite to said handle, said channel shaped handle having a pair of opposing sidewalls joined by a bottom wall, said knife blade having a longitudinal cutting edge, the other of said jaw members being channel shaped with a pair of opposing sidewalls joined by a top wall and forming a handle at one end and a cradle with a generally semi-circular cutting cage and an upstanding end wall at the other end, said handle and cradle integrally joined together with a mounting block, a knife receiving slot in the mounting block, cradle and upstanding end wall for receiving the cutting edge of said knife blade when said handles are closed together with the channel-shaped handle of the first jaw member opposed to an nested within the channel0shaped second jaw member, said pivot pin being longitudinally adjustable stepwise in the mounting block relative to the second jaw member for changing the pivot axis of the first jaw member thereby changing the effective cutting cage of the cradle and the angle at which the cutting edge of the knife blade makes on initial contact with the pipe and tubing.
A cutter adapted for cutting a range of different diameter plastic pipe and tubing comprising a pair of jaw members pivotally connected intermediate their ends, a pivot pin about which a first of the jaw members is pivoted within a second of the jaw members, the first jaw member having a channel-shaped handle at one end and a knife blade extending from the other end opposite to said handle, said channel shaped handle having a pair of opposing sidewalls joined by a bottom wall with a finger loop for trigger for pivoting open the cutter, said knife blade having a longitudinal cutting edge, the other of said jaw members being channel shaped with a pair of opposing sidewalls joined by a top wall and forming a handle at one end and a cradle with a generally semi-circular cutting cage and an upstanding end wall at the other end, said handle and cradle integrally joined together with a mounting block, a knife receiving slot in the mounting block, cradle and upstanding end wall for receiving the cutting edge of said knife blade when said handles are closed together with the channel-shaped handle of the first jaw member opposed to and nested within the channel-shaped second jaw member, said pivot pin being longitudinally adjustable stepwise relative to the second jaw member for changing the pivot axis of the first jaw. member thereby changing the effective cutting cage of the cradle and the angle at which the cutting edge of the knife blade makes on initial contact with the pipe and tubing.
