Abstract
Abstract A tool component adapted to be connected to another element of a tool assembly includes a rearwardly facing surface and a truncated conical recess extending rearwardly therefrom. The recess is adapted to receive a correspondingly configured projection of the other element. A portion of the rearwardly facing surface defines a support surface engageable with the other element. The recess is non-circular in cross-section so as to be rendered non-rotatable relative to the other element. The recess includes a rearwardly open hole extending along the axis and a threaded fastening bolt disposed in the hole to draw the projection into the recess.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
A tool component for a tool assembly, said component adapted to be connected to another element of the assembly, said component comprising a body defining a front-to-rear extending center axis, said body including a rearwardly facing surface and a truncated conical recess extending rearwardly from said rearwardly facing surface and adapted to receive a correspondingly configured projection of the other element, a portion of said rearwardly facing surface disposed laterally outwardly of said recess defining a support surface engageable with the other element, said recess being non-circular in a cross-section taken perpendicular to said center axis so as to be rendered non-rotatable relative to the other element when receiving the projection thereof, said recess including a rearwardly open hole extending along said axis and a threaded fastening bolt disposed in said hole to draw the projection into said recess.
Claim 2
Dependent Claim
139 words
A tool component for a tool assembly, said component adapted to be connected to another element of the assembly, said component comprising a body defining a front-to-rear extending center axis, said body including a rearwardly facing surface and a truncated conical recess extending rearwardly from said rearwardly facing surface and adapted to receive a correspondingly configured projection of the other element, a portion of said rearwardly facing surface disposed laterally outwardly of said recess defining a support surface engageable with the other element, said recess being non-circular in a cross-section taken perpendicular to said center axis so as to be rendered non-rotatable relative to the other element when receiving the projection thereof, said recess including a rearwardly open hole extending along said axis and a threaded fastening bolt disposed in said hole to draw the projection into said recess.
Claim 3
Dependent Claim
29 words
Tool component according to claim 1, wherein a surface of said recess in cross-section has at least one portion which extends radially beyond a circle inscribed within the cross-section.
Claim 4
Dependent Claim

Claim 7
Dependent Claim
32 words
A tool component according to claim 1, wherein said recess is three-sided, each side being convexly curved as said recess is viewed in cross-section, said three sides being of equal circumferential length.
Claim 8
Dependent Claim
19 words
A tool component according to claim 1, wherein said tool component comprises a tool holder for receiving a tool.
Claim 9
Dependent Claim
24 words
