ABSTRACT:
Within a rigid housing cavity, freely moveably received members respectively support oppositely oriented spaced needles. Double "T" bar end type attachments situated between parallel connector bars are dispensed through the needles to attach buttons. Depressing protrusions accessible from the exterior of the housing moves the needle support members to alter the needle spacing to accomodate buttons with a variety of thread hole spacings. In order to reduce the peak force necessary to sever the attachments from the connector bars, the connector bars are severed from the ends of each attachment at slightly different times during the trigger stroke. A triangular linkage associated with the trigger provides a mechanical advantage which increases at an increasing rate, transmitting maximum force towards the end of the stroke, as the filament connecting the "T" bars stretches around the portion of the button between the thread holes. The ejector rods are moveably mounted such that alignment between each ejector rod and the associated needle is maintained regardless of changes in the relative position of the needles.
