Abstract
Plier-like grommet-setting tool has integral pyramidal punch and annular fabric cutter on one jaw and turntable on opposite jaw. Turntable presents two zones, one for cutting a hole in the fabric with the use of the cutter, and the other for setting the grommet eyelet with the use of the punch. Turntable may be readily shifted to present the proper zone under the punch. The tool is especially adapted for setting heavy-duty eyelets and grommets.
Claims5
A plier-like grommet-setting tool having a pair of opposing swinging jaws and including:
- a pyramidal punch attached to one of the jaws facing the other jaw and having planar inclined sides with eyelet barrel-cutting edges at the juncture of adjacent sides, the punch narrowing as its distal end is approached, the base of the punch being surrounded by an annular eyelet-rolling trough also facing the other jaw, the punch having an annular cutter at the distal end thereof, the cutter facing the said other jaw;
- a turntable of tough plastic pivotally attached to the said other jaw, the turntable having a substantially planar surface facing said one jaw, the surface having separate working zones, which may be selectively brought into alignment with the punch by rotating the turntable when the jaws are open, one of the zones being flat and adapted to serve as impingement surface for the annular cutter when the jaws are closed with fabric inbetween, the other of the zones having a recess adapted to accommodate at least part of the punch, and an annular depression surrounding the recess for holding the flange of an eyelet during the rolling of the eyelet barrel by the punch.
A plier-like grommet setting tool having a pair of opposing swinging jaws and including on one jaw a pyramidal punch having an annular cutter at its smaller distal end and on the other jaw a plastic turntable having working zones, one zone having indented means to hold an eyelet flange while the eyelet barrel is being rolled by the punch, and the other zone having flat impingement means adapted to work with the cutter when the jaws are closed on a piece of fabric, the zones being selectively alignable under the punch by rotation of the turntable.
