Abstract
A device for dispensing a plastic staple from fastener stock includes a housing, an ejection mechanism for dispensing the staple, a severing mechanism for separating the staple from the fastener stock and an indexing mechanism for advancing the fastener stock into the housing. The ejection mechanism includes a pair of needles, a pair of movable slides, a pair of ejector rods and an actuator pin extending perpendicularly between the slides. The severing mechanism includes a pivotally mounted cam having a non-linear slot which receives the actuator pin and a knife blade coupled to the cam. The indexing mechanism includes a feed slide and a rotatable feed dog for displacing the feed slide. The feed slide includes a pair of inwardly compressible spring arms which sequentially engage the fastener stock. During the ejection process, the actuator pin travels horizontally within the housing and selectively pivots the cam and the feed dog.
