An impact device, useful for driving nails, staples and other fastening elements. The driving member is driven by frictional engagement with a rotating high speed flywheel. The device has a safety provision whereby it cannot be actuated until the nose of the device is pressed against a work piece. This action also produces a movement of a support means, such as a roller, towards the rotating flywheel. It should be pointed out that the tool could be designed, in the alternative, with a fixed support means and movable flywheel. Actuation of the trigger mov...


An impact tool comprising: (a) an impact member; (b) a rotatable flywheel and means to drive the same, and support means spaced apart by less than the thickness of the impact member; (c) means for introducing the impact member between said flywheel and said support means; and (d) means permitting at least one of said flywheel and support means to yield with respect to the other to permit the impact member to pass therebetween, while maintaining force against the impact member.
