DEVICE FOR HAMMERING IN ELEMENTS BY THE POWER OF GUNPOWDER, CONNECTED TO AN APPARATUS FOR LEADING MAGAZINES

摘要

In an explosive charge-driven setting gun using a piston for inserting fastening elements into a receiving material, a feed mechanism is pivotally connected to the gun body so that it can selectively position fastening elements in alignment with the muzzle opening in the gun body and move the piston into the firing position. The feed mechanism forms a guideway for a magazine holding the fastening elements and a pawl in the feed mechanism moves the magazine for positioning the fastening elements in alignment with the muzzle opening. During each complete cycle of pivotal movement of the fastening mechanism, a fastening element is moved into the firing position and the pawl is displaced for moving the next fastening element into the firing position.
