Bench plane

A bench plane, comprising:

• (a) a plane body having a sole penetrated by a mouth,
• (b) a frog adjustably attached to the body and having:
• (i) a foot extending through the mouth and having a surface co-planar with the sole, and
• (ii) tines that project from the frog,
• (c) a handle secured to the frog between tines that project from the frog,
• (d) a blade positioned against the frog, the blade having:
• (i) a cutting arris formed by intersection between a back bevel and another surface, and
• (ii) an opposed pair of side edges,
• (e) a blade adjustment mechanism positioned between a portion of the blade and the frog,
• (f) two set screws in the body, one of which set screws contacts each of the pair of blade opposed side edges,
• (g) a chip breaker secured to the blade,
• (h) a lever cap securing the blade and the chip breaker to the frog,
• (i) two screws longitudinally centered on the plane body for adjustably securing the frog to the plane body, both of which are accessible when the blade and the chip breaker are secured to the frog, and
• (j) a thumbnut captured within the frog and threaded onto a screw shaft attached to the body for adjusting the longitudinal position of the frog on the body.

A bench plane, comprising:

• a plane body having a sole,
• a plane blade having a front surface, a back surface, two sides, and a bevel intersecting (a) the front surface or another surface of the blade to form a cutting arris, and (b) the back surface,
• a frog attached to the plane body and to which the blade is adjustably attached, the frog having a frog foot having a sloping surface along which the blade slides during adjustment and that is in contact with the blade at least immediately adjacent to the intersection of the blade back surface and the bevel,
• a chip breaker secured to the blade,
• a lever cap securing the blade and the chip breaker to the frog, and
• two screws longitudinally centered on the plane body securing the frog to the body, one of which screws is accessible through openings in the lever cap, the chip breaker and the blade.

A kit for providing (1) a bench plane having plane sole both in front and in back of a plane blade cutting arris and (2) a chisel plane having plane sole only in back of the plane blade cutting arris, the kit comprising:

• a handle attached to a frog having planar structure for contact with a plane body structure,
• a blade attached to the frog, the blade having a front surface, a back surface, and a bevel intersecting (a) the front surface or another surface of the blade to form a cutting arris, and (b) the back surface,
• a bench plane body attachable to the frog and having a bench plane body planar structure for contact with the frog planar structure and having a sole structure to provide plane sole both in front and in back of the blade, and
• a chisel plane body attachable to the frog and having a chisel plane body planar structure for contact with the frog planar structure and having a sole structure to provide plane sole only in back of the blade,
• the frog having a foot that:
• (a) projects below the plane of the planar structure of the respective one of the bench plane body or the chisel plane body when the frog is attached to one of the plane bodies, and
• (b) has a sloping surface along which the blade slides during adjustment and that is in contact with the blade at least immediately adjacent to the intersection of the blade back surface and the bevel.

A kit for providing (1) a bench plane having a first length and (2) a bench plane having a second length, the kit comprising:

• a handle attached to a frog,
• a blade attached to the frog, the blade having a front surface, a back surface, two sides, and a bevel intersecting (a) the front surface or another surface of the blade to from a cutting arris, and (b) the back surface,
• a first bench plane body having a mouth and a first length attachable to the frog,
• a second bench plane body having a mouth and a second length different from the first length attachable to the frog, and
• wherein the frog has a frog foot that projects into the mouth of the first plane body or the mouth of the second plane body when the frog is attached to a respective one of the two plane bodies and having a sloping surface along which the blade slides during adjustment and that is in contact with the blade at least immediately adjacent to the intersection of the blade back surface and the bevel.

An assembly for attachment to a bench plane body to provide a bench plane, comprising:

• a blade having a back surface, a front surface, and a cutting arris defined, in part, by a bevel intersecting the back surface,
• a frog attached to the blade and having a planar structure for contact with the plane body and foot projecting below the planar structure and having a sloping surface and a bottom surface for contact with a workpiece,
• a handle attached to the frog, and
• a mechanism for adjusting projection of the blade from the frog and tilt of the blade cutting arris relative to the frog.

A bench plane frog assembly, comprising:

• a frog adapted to be secured to the bed of a metal plane body,
• a rear handle attached to the frog,
• a blade having a back face terminating at an arris-forming bevel at one end of the blade and a cutting arris formed by the bevel,
• a chip breaker, and
• a lever cap securing the blade and the chip breaker to the frog, the frog having a planar structure for contact with a plane body and a frog foot projecting below the planar structure and having a sloping surface along which the blade slides during adjustment and that is in contact with the blade below the plane of the frog planar structure and at least immediately adjacent to the intersection of the blade back face and the bevel.
