Abstract
Abstract This disclosure relates to a simplified integral button attacher without any moving parts. The attacher consists of a needle having a slotted portion therein for insertion of one end of an improved fastener into the free end of the slotted portion and gripping means portion for simultaneously pushing said fastener loaded needle through a button aperture and the fabric to which it is to be attached. Each of the improved fasteners have a vertical shaft with two sets of non-parallel transverse bars equally extending at each end thereof. The angular shape of the fasteners allows easier entry as needle and fasteners penetrate button and fabric. The angular shape also stresses the end bars and forces them to lie tightly against the under surface of the fabric.
