Patent number: 8960518Abstract: The invention relates to a device for setting fasteners, in particular a driving tool, comprising at least one striking pin for a particular fastener, wherein the striking pin and the fastener to be set by the striking pin are guided at least in some sections in a channel, which comprises at least one stationary channel part and a channel closure flap arranged so as to be pivotable relative to the channel part. The channel closure flap is held at the upper end thereof by an eccentric shaft that can be adjusted about the rotational axis, wherein the closure flap comprises at least one holding part corresponding to the channel part for forming a lock. The eccentric shaft preferably comprises two end sections oriented coaxially to each other and a center part arranged eccentrically to the end sections, wherein the closure flap is rotatably mounted on the center part of the eccentric shaft.Type: GrantFiled: January 8, 2010Date of Patent: February 24, 2015Assignee: Illinois Tool Works Inc.Inventors: Torsten Weigmann, Olaf Hahndel

Patent number: 8733609Abstract: In a fastening apparatus, a lockable slider is movably held along a magazine carrier, and coupled to a feeding element for a movement of fastening elements into an operating position below a firing pin. An adjustable retaining part for locking the slider is disposed on the magazine carrier, and has, in its locking position, at least one component section which protrudes into the feed path of the slider for a form closure with the slider in its locking position. The component section has at least one sliding surface running obliquely to the guide surfaces of the magazine carrier for shifting the retaining part from the locking position. The retaining part has a shoulder running approximately perpendicularly to the guide surfaces of the magazine carrier, which is configured so that it directly adjoins the obliquely running sliding surface.Type: GrantFiled: February 17, 2010Date of Patent: May 27, 2014Assignee: Illinois Tool Works Inc.Inventors: Torsten Weigmann, Olaf Hahndel
