Abstract

Abstract A toolholder for supporting thin rotary tools is disclosed, utilizing first and second tool rings having flange portions for respectively clamping and driving the sides of a rotary tool such as a thin grinding wheel, wherein the respective tool rings have generally circular tool support sections adjacent to their flange portions, and the circular tool support sections are relieved so as to form facial teeth or lugs on the two rings, and the respective teeth of the one ring engage the tooth spaces of the other ring and vice versa, when the rings are clamped against a thin tool. The first tool ring is adapted to locate and drive with a rotatable tool spindle, and the second tool ring is adapted to be carried in a concentric manner with the first ring and means is provided for clamping the rings together and enmeshing the respective tool support sections, so that a tool having a thickness equal to or less than the combined length of each tool support section of the respective rings may be clamped and supported on a substantially continuous bore support surface.

Claim 1
Independent Claim 182 words
A toolholder for supporting thin rotary tools, comprising: (a) a first tool ring having (1) a generally circular tool support section, (2) a flanged shoulder portion adjacent to said support section, (3) facial tooth means and tooth space means formed in said support section, (4) means for locating and driving said ring with a rotatable tool spindle; (b) a second tool ring having (1) a generally circular tool support section, (2) a flanged shoulder portion adjacent to said support section, (3) facial tool means and tooth space means formed in said support section; (c) means for supporting said first and second rings in a concentric manner with each other and with the tooth means of one ring aligned with and disposed facing the tooth space means of the other ring; and (d) means for clamping said rings together enmeshing respective tool support sections of said rings whereby a tool having a thickness equal to or less than the combined lengths of each of said tool support sections of said rings may be clamped and supported on a substantially continuous bore support surface.
Claim 2
Dependent Claim 182 words
A toolholder for supporting thin rotary tools, comprising: (a) a first tool ring having (1) a generally circular tool support section, (2) a flanged shoulder portion adjacent to said support section, (3) facial tooth means and tooth space means formed in said support section, (4) means for locating and driving said ring with a rotatable tool spindle; (b) a second tool ring having (1) a generally circular tool support section, (2) a flanged shoulder portion adjacent to said support section, (3) facial tool means and tooth space means formed in said support section; (c) means for supporting said first and second rings in a concentric manner with each other and with the tooth means of one ring aligned with and disposed facing the tooth space means of the other ring; and (d) means for clamping said rings together enmeshing respective tool support sections of said rings whereby a tool having a thickness equal to or less than the combined lengths of each of said tool support sections of said rings may be clamped and supported on a substantially continuous bore support surface.
