Abstract
Abstract A combination tool and tool holder assembly, the tool holder member of which comprises upper and lower sides and converging edge portions which define a tool support section; a tool member adapted for operative support on the tool support section and having one or more cutting portions adapted to overlie the converging edge portions thereof so as to project outwardly therefrom for engagement with a workpiece to be machined; means for operatively securing the tool member on the tool holder member, and means for resisting rotational, transverse and longitudinal movement of the tool member relative to the tool holder member including a generally channellike recess formed on one side of one of the members and a complementary shaped embossed portion formed on the confronting side of the other of the members adapted for operative engagement with the recess.

Total Claims: 4
Claim 1
Independent Claim
346 words
In combination in a tool and tool holder assembly, a tool holder member comprising an elongated body having upper and lower sides and converging edge portions defining a tool supporting section, said supporting section having a generally planar first engageable surface, a tool member adapted to be operatively mounted on said surface and having a cutting portion adapted to overlie said converging edge portions thereof so as to project outwardly therefrom for engagement with a workpiece, said tool member having upper and lower generally planar second engageable surfaces adapted to alternately engage said first surface on said supporting section of said holder member upon mounting of said tool member thereon, fastening means extending between said members for securing said tool member on said tool holder, and means for resisting rotational, transverse and longitudinal movement of said tool member relative to said tool holder member including a pair of generally channellike recess means formed in said first engageable surface of said tool holder member or both of said second engageable surfaces of said tool member, one of said recess means extending longitudinally of said tool holder member and the other of said recess means extending transversely of said tool holder member, and a pair of embossed means formed on the other of said first engageable surface of said tool holder member or both of said second engageable surfaces of said tool member, one of said embossed means extending longitudinally of said tool holder member and the other of the embossed portions extending transversely of said tool holder member, said recess means and said embossed means being of a complementary shape and having tapered mutually engageable sidE surfaces, and means defining aligned openings at the intersection of said embossed portions and said channellike recesses adapted for reception of said fastening means, whereby said tool member may be selectively inverted upon said holder member and said embossed means may be nestingly engageable within said recess means in either inverted position of said tool member for resisting said relative movement of said tool member with respect to said holder member.
Claim 2
Dependent Claim
346 words
In combination in a tool and tool holder assembly, a tool holder member comprising an elongated body having upper and lower sides and converging edge portions defining a tool supporting section, said supporting section having a generally planar first engageable surface, a tool member adapted to be operatively mounted on said surface and having a cutting portion adapted to overlie said converging edge portions thereof so as to project outwardly therefrom for engagement with a workpiece, said tool member having upper and lower generally planar second engageable surfaces adapted to alternately engage said first surface on said supporting section of said holder member upon mounting of said tool member thereon, fastening means extending between said members for securing said tool member on said tool holder, and means for resisting rotational, transverse and longitudinal movement of said tool member relative to said tool holder member including a pair of generally channellike recess means formed in said first engageable surface of said tool holder member or both of said second engageable surfaces of said tool member, one of said recess means extending longitudinally of said tool holder member and the other of said recess means extending transversely of said tool holder member, and a pair of embossed means formed on the other of said first engageable surface of said tool holder member or both of said second engageable surfaces of said tool member, one of said embossed means extending longitudinally of said tool holder member and the other of the embossed portions extending transversely of said tool holder member, said recess means and said embossed means being of a complementary shape and having tapered mutually engageable sidE surfaces, and means defining aligned openings at the intersection of said embossed portions and said channellike recesses adapted for reception of said fastening means, whereby said tool member may be selectively inverted upon said holder member and said embossed means may be nestingly engageable within said recess means in either inverted position of said tool member for resisting said relative movement of said tool member with respect to said holder member.
Claim 3
Dependent Claim
229 words
In combination in a tool and tool holder assembly, a tool holder member comprising an elongated body having upper and lower sides and converging edge portions defining a tool-supporting section, a tool member adapted to be operatively supported on said section of said tool holder member and having a cutting portion adapted to overlie said converging edge portions thereof so as to project outwardly therefrom for engagement with a workpiece, fastening means for securing said tool member on said tool holder, and means for resisting rotational, transverse and longitudinal movement of said tool member relative to said tool holder member, said last-mentioned means including first and second channellike recesses formed in said tool-supporting section of said tool holder member, one of said recesses extending longitudinally of said tool holder member and the other of said recesses extending transversely of said member, first and second sets of embossed portions formed on the upper and lower sides of said tool member, one of the embossed portions of each set thereof extending longitudinally of said tool holder member and the other of the embossed portions of each set thereof extending transversely of said tool holder member, said embossed portions and said channellike recesses having tapered mutually engageable side surfaces, and means defining aligned openings at the intersection of said embossed portions and said channellike recesses adapted for reception of said fastening means.
Claim 4
Dependent Claim
229 words
In combination in a tool and tool holder assembly, a tool holder member comprising an elongated body having upper and lower sides and converging edge portions defining a tool-supporting section, a tool member adapted to be operatively supported on said section of said tool holder member and having a cutting portion adapted to overlie said converging edge portions thereof so as to project outwardly therefrom for engagement with a workpiece, fastening means for securing said tool member on said tool holder, and means for resisting rotational, transverse and longitudinal movement of said tool member relative to said tool holder member, said last-mentioned means including first and second channellike recesses formed in said tool-supporting section of said tool holder member, one of said recesses extending longitudinally of said tool holder member and the other of said recesses extending transversely of said member, first and second sets of embossed portions formed on the upper and lower sides of said tool member, one of the embossed portions of each set thereof extending longitudinally of said tool holder member and the other of the embossed portions of each set thereof extending transversely of said tool holder member, said embossed portions and said channellike recesses having tapered mutually engageable side surfaces, and means defining aligned openings at the intersection of said embossed portions and said channellike recesses adapted for reception of said fastening means.
