Claim 8

The portable handheld planer of claim 6, wherein said one side of the housing is provided with a channel in which said elongated member and an upstanding elongated portion of the guard means are positioned.

Claim 9

The portable handheld planer of claim 4, further comprising fence means, at the opposite side of the housing, including a bracket having an essentially upstanding portion and an essentially horizontal portion, the horizontal portion extending outwardly from the side of the housing, an elongated member below said horizontal portion adapted and constructed to be clamped together at a predetermined position, the end of the elongated member proximate the housing having a wall normal to the elongated member and disposed to be movable under the planing tool and housing to achieve a desirable fixed position.

Claim 10

A portable handheld planer for planing a workpiece, comprising: a housing containing a substantially cylindrical planing tool rotatably mounted for rotation about a horizontal axis; a motor for driving the planing tool; a combination guard and adjustable rabbeting depth gauge mounted on one side of said housing, and comprising guard means, resilient means, abutment means, and stop means; said guard means being mounted adjacent one end of the planing tool for blocking access to said end during the planing operation, and being slideably mounted in the housing for movement in a direction transverse to said horizontal axis; said resilient means resiliently urging said guard means downwardly for engagement with the workpiece into which a rabbet cut is to be made; said abutment means limiting downward movement of said guard means; said stop means being adjustable in elevation for controlling the extent to which the guard means may be moved upwardly during the planning operation thereby adjustably setting the depth to which the rabbet cut is to be made; and fence means, mounted on the other side of said housing, for controlling the width of the rabbet cut.

Claim 11

A portable handheld planer for planing a workpiece, comprising: a housing containing a substantially cylindrical planing tool rotatably mounted for rotation about a horizontal axis; a motor for driving the planing tool; a combination guard and adjustable rabbeting depth gauge mounted on one side of said housing, and comprising guard means, resilient means, abutment means, and stop means; said guard means being mounted adjacent one end of the planing tool for blocking access to said end during the planing operation, and being slideably mounted in the housing for movement in a direction transverse to said horizontal axis; said resilient means resiliently urging said guard means downwardly for engagement with the workpiece into which a rabbet cut is to be made; said abutment means limiting downward movement of said guard means; said stop means being adjustable in elevation for controlling the extent to which the guard means may be moved upwardly during the planning operation thereby adjustably setting the depth to which the rabbet cut is to be made; and fence means, mounted on the other side of said housing, for controlling the width of the rabbet cut.

Claim 12

The portable handheld planer of claim 9, further comprising: shoe means, connected to said housing, for supporting the planer on the workpiece, and in conjunction with said planing tool determining the size of the cut produced by each pass during the planing operation; and wherein said guard means is movable relative to said shoe means and said resilient means yieldably allows upward movement of said guard means relative to said shoe means while a rabbet is being cut.

Claim 13

The portable handheld planer of claim 1 or 10, wherein said shoe means has a rear shoe extending rearwardly of said planing tool, and a forward shoe extending forwardly of said planing tool, said forward shoe being adjustable vertically with respect to said rear shoe for adjusting the size of cut produced during each said pass.

Claim 14

A portable handheld planer for planing a workpiece, comprising: a housing having a vertically disposed channel therein; a planing tool rotatably mounted in said housing; a motor mounted in said housing for driving said planing tool; forward and rear shoes forming the bottom of said housing and adapted to support the planer on the workpiece, there being an opening between said shoes through which said planing tool extends to a small extent; a guard plate disposed vertically and to one side of said shoes adjacent to one end of said planing tool for blocking access thereto, and having an upward extension slideably mounted in said channel to permit vertical movement of said guard plate relative to said shoes, said guard plate having a horizontally disposed shoe at the bottom thereof, said guard plate shoe being disposed adjacent and outwardly of said one end of said planing tool and adapted to slideably engage an unplaned portion of the workpiece; abutment means, associated with said channel, for limiting the downward movement of said guard plate thereby determining the lowest position thereof; a stop member mounted in said channel and adjustable vertically therein for controlling the extent to which said guard plate shoe can be moved upwardly relative to said housing bottom, whereby the depth is set to which the completed rabbet will be made; resilient means for urging said guard plate downwardly against the unplaned portion of the workpiece, whereby whenever the planer is raised from the work piece said guard plate is urged downwardly to said lowest position; and a fence assembly adjustably mounted on the other side of said housing, and having a fence parallel to said guard plate and adjustable theretowards and away therefrom to determine the width of the rabbet.

Claim 15

A portable handheld planer for planing a workpiece, comprising: a housing having a vertically disposed channel therein; a planing tool rotatably mounted in said housing; a motor mounted in said housing for driving said planing tool; forward and rear shoes forming the bottom of said housing and adapted to support the planer on the workpiece, there being an opening between said shoes through which said planing tool extends to a small extent; a guard plate disposed vertically and to one side of said shoes adjacent to one end of said planing tool for blocking access thereto, and having an upward extension slideably mounted in said channel to permit vertical movement of said guard plate relative to said shoes, said guard plate having a horizontally disposed shoe at the bottom thereof, said guard plate shoe being disposed adjacent and outwardly of said one end of said planing tool and adapted to slideably engage an unplaned portion of the workpiece; abutment means, associated with said channel, for limiting the downward movement of said guard plate thereby determining the lowest position thereof; a stop member mounted in said channel and adjustable vertically therein for controlling the extent to which said guard plate shoe can be moved upwardly relative to said housing bottom, whereby the depth is set to which the completed rabbet will be made; resilient means for urging said guard plate downwardly against the unplaned portion of the workpiece, whereby whenever the planer is raised from the work piece said guard plate is urged downwardly to said lowest position; and a fence assembly adjustably mounted on the other side of said housing, and having a fence parallel to said guard plate and adjustable theretowards and away therefrom to determine the width of the rabbet.
