Abstract
A button attaching device for attaching a button to a layer of material includes a C-frame having a top portion, an intermediate portion and a bottom portion. A plurality of needle block assemblies are disposed inside the top portion of the C-frame in a stack. A manually operable plunger is slidably mounted on the top portion of the C-frame for up and down movement and positioned to receive and move downward the lowermost needle block assembly in the stack. Each needle block assembly includes a block of elastomeric material, a pair of rodless fastener dispensing needles and a fastener of the type having a foot at each end of a filament. Each foot is removably mounted on one of the pair of rodless fastener dispensing needles. In use, a button and a layer of material to which the button is to be attached are positioned on top of an anvil formed on the bottom portion of the C-frame. The lowermost needle block assembly is pushed down by the plunger so that the needles extend through a pair of holes in the button and through the layer of material. The plunger is then retracted leaving the button secured to the layer of material by the fastener.
