Abstract
A planer including a housing having a base planing surface for contacting a workpiece, a rotatable blade cylinder located within said housing and including more than one cutting blade for engaging with and planing the work piece. A drive means is associated with the blade cylinder and operable to cause rotation of the blade cylinder. The drive means is located within the housing, above the axis of rotation of the blade cylinder and a chip an debris removal channel passes from the location of the cylinder to the rear end of the planer.
Claims20
A powered planer tool, said planer tool having a cylinder with at least one cutter blade mounted thereon;
- a motor to cause the cylinder to rotate about an axis of rotation with a portion of the cylinder exposed through an opening in a planing surface of the planer to cause the removal of material from a surface of a workpiece along which the planing surface is moved;
- said cylinder and motor mounted within a housing and wherein the motor is positioned in the housing above the axis of rotation of the cylinder;
- and
- the housing includes a chip and debris removal system, said system, said system has at least one channel that passes from an opening at or adjacent to a blade chamber in which the cylinder is located, said channel leading to at least two passages, each passage having an opening to allow the passage of chips and debris from the housing, with one passage leading to an opening on a first side of the housing to the rear of the blade chamber, and the other passage leading to an opening at a rear or the other side of the housing to the rear of the blade chamber.
A powered planer tool, said planer tool having a cylinder with at least one cutter blade mounted thereon;
- a motor to cause the cylinder to rotate about an axis of rotation with a portion of the cylinder exposed through an opening in a planing surface of the planer to cause the removal of material from a surface along which the planing surface is moved;
- said cylinder and motor mounted within a housing and wherein the cylinder for the planer is provided with more than two straight cutting blades;
- said blades positioned substantially 120 degrees or less, apart around the cylinder periphery;
- and
- the housing includes a chip and debris removal system, said system has at least one channel that passes from an opening at or adjacent to a blade chamber in which the cylinder is located, each channel leading to at least two passages, each passage having an opening to allow the passage of chips and debris from the housing, with one passage leading to an opening on a first side of the housing to the rear of the blade chamber, and the other passage leading to an opening at a rear or the other side of the housing to the rear of the blade chamber.
A powered planer tool, said planer tool comprising:
- a cylinder with at least one cutter blade mounted thereon;
- a motor to cause the cylinder to rotate about an axis of rotation with a portion of the cylinder exposed through an opening in a planing surface of the planer to cause the removal of material from a surface along which the planing surface is moved;
- said cylinder and motor mounted within a housing and wherein the blade cylinder for the planer is provided with two or more helically shaped blades;
- said blades positioned substantially 180 degrees or less, apart around the cylinder periphery;
- and
- the housing includes a chip and debris removal system, said system has at least one channel that passes from an opening at or adjacent to a blade chamber in which the cylinder is located, each channel leading to a passage, each passage having an opening to allow the passage of chips and debris from the housing, with one passage leading to an opening on a first side of the housing to the rear of the blade chamber, and the other passage leading to an opening at a rear or the other side of the housing to the rear of the blade chamber.
