Abstract
A hammer tacker has a strike, a tack-driving piston, a tack-feeding mechanism, and a handle for a user to cause a strike against a target. The piston cycles between drive and retraction strokes. The tack-feeding mechanism cycles between recession and feed strokes to feed the tack in a next-to-lead position to the lead position after the preceding tack in the lead position is struck into the target, and includes an escaping driver for engaging a pallet of the tack in the next-to-lead position during the feed stroke to feed that tack to the lead position, as well as for escaping the pallet of that tack during the recession stroke and then receding to engage the pallet of the tack that succeeds to the next-to-lead position, if any. Wherein as the piston's drive stroke coincides with the recession stroke, the feed stroke lags after a pause behind the piston's retraction stroke.
