ABSTRACT:
Double "T" bar fasteners are dispensed through spaced needles which extend from different portions of the attacher housing. To attach a button, the needles are inserted through the thread holes of the button as it is held adjacent to the material to which it is to be attached. The housing portions are resiliently connected so that the portions can be moved relative to each other to vary the needle spacing and thus accommodate buttons with different hole spacing. The portions are biased to return to the original position. The portions may be halves of the housing connected by a living hinge. Internal compartments within each housing half enclose portions of fastener feed mechanism. The compartments are accessible when the housing is open to permit insertion of the parts and close when the housing halves snap-fit together. Each feed mechanism portion includes a spring loaded pawl with a tooth which normally engages an index wheel. The pawls are manually caused to travel along a path defined by oval guide tracks in the housing wall to cause the index wheels to simultaneously rotate and feed the fasteners.
