ABSTRACT:
Disclosed is an apparatus for attaching an ornament by a pronged setting to sheet material, which includes a base having an anvil in the form of a turret on which the sheet material is placed and a pivotally connected head which receives the setting. A plunger on the head registers with the anvil when the head is pivoted relative to and toward the base. The plunger comprises a sleeve and a punch reciprocable axially within the sleeve. The sleeve contacts the sheet material and holds it in engagement with the anvil, and the punch moves axially within the sleeve to force the prongs of the setting into and through the sheet material and to deform the prongs so as to fasten the ornament to the material. A spring is disposed between the sleeve and the plunger to permit relative axial movement therebetween and to bias them apart after the ornament has been affixed. A pin extends radially through registered slots in the punch and the sleeve to attach them together and to limit the extent of relative movement therebetween. The slots are arranged in a manner which greatly facilitates the manufacture and assembly of the punch and sleeve. Different plungers can be readily attached to the head for use with different ornaments.
