Description: |
| Abstract:
An object of my invention is the-provision of a fixture or a mechanism for holding and guiding a tool that is to be ground in cooperative grinding relationship with a grinding device such as, for example, a rotary or abrasive grinder.
Claim:
In a mechanism for holding and guiding a tool having a longitudinal spiral portion with a longitudinal cutting edge that is adapted to be ground by passing the same longitudinally and rotatively along a grinder having a grinding surface of less width than the longitudinal length of the spiral cutting edge, thus making the spiral cutting edge that is ground project beyond the grinding surface of the grinder, in combination, means for holding the said tool, a header, means for slidably and rotatively mounting the tool holding means in the header, so that the tool may be longitudinally and rotatively passed along the grinding surface of the grinder, thus making the spiral cutting edge that is ground project beyond the grinding surface of the grinder, a guide adapted to engage the longitudinal spiral portion of the said tool and thus constrain the said longitudinal cutting edge, when the tool is longitudinally passed In the feeding direction along the grinding surface of the grinder, to ride upon the guide and thereby rotate and align itself relative to the grinding surface of the grinder, means for mounting the guide to the header, a base, means for pivotally mounting the header to the base so that the spiral portion of the tool, which has been rotated by the guide relative to the grinding surface of the grinder during the feeding movement and which by reason of the spiral tends to leave the guide upon its return movement, may be pivoted away from the grinding surface of the grinder and thereby allow the ground spiral cutting edge to be returned to its initial feeding position without being damaged by contacting the grinding surface of the grinder. |
