Abstract:

Apparatus for repairing portions of damaged material such as clothing fabric is described. A piece of mending cloth identical to the damaged material is placed over the damaged area of a fabric to be repaired, aligned and further placed upon a flat cutting die of metal having several different sized round holes therein. The proper hole is selected, the top edge about the parimeter acting as the cutting die. A cooperating punch assembly containing a cylindrical holder which can contain one metal sphere or two such spheres. If the punch assembly contains two such spheres, one may be swiveled or turned end for end so as to cut with the desired sphere. The spherical ball partically protrudes from the one end of a holder through a hole about which surrounds a shoulder area for cooperating with the die plate. The spherical ball is held loosely within the holder by retaining means opposite to the shoulder region. A rigid shaft, spring loaded extends from that part of the sphere remote from the fabric striking end of the sphere to the outer end of the cylindrical holder.
