Latest Patents

Murphy holds a patent for a "Variable pitch feed of fasteners." This invention features a unitary, single toothed feed pawl that enhances the efficiency of fastener feeding. In the first embodiment, the design prevents back-up of the fasteners using a downwardly pointed detent tooth that bites into a secondary runner bar of the fastener assemblage, ideally positioned beyond the fastener ejection axis. The second embodiment includes a secondary runner bar with a series of lands spaced at the same pitch as the fasteners. Here, the detent comprises a pin biased toward the runner bar, allowing it to intermittently engage the lands. This innovative design ensures that individual fasteners are securely positioned for ejection, effectively preventing back-up of the fastener assemblage.
