Patent number: 6341542Abstract: An automatic screwing device, especially a hand screwdriver, consisting of a screwdriver and a collet to hold a secured protruding screw. The screwdriver is coupled to an actuating device so that it can rotate and move forward in relation to the collet. The actuating device has a first threaded element which can be driven rotationally and connected to the screwdriver and at least a second threaded element which is connected to the collet and interacts with the first threaded element. By providing two different thread pitches on the first and/or second element the screwdriver can advance at two different speeds while rotational speed of the first element remains the same.Type: GrantFiled: April 7, 1999Date of Patent: January 29, 2002Assignee: Weber Schraubautomaten GmbHInventors: Reiner Ade, Wolfgang Listmeier, Bolger Wolf

Patent number: 4856389Abstract: The invention relates to a device for setting fastener elements or pins, particularly to a screw-setting device. The device comprises a housing in which a retainer shaft for a setting tool is mounted at least for axial displacement, at least one advance drive mechanism within the housing and adapted to be connected to the retainer shaft, a switching sleeve mounted for displacement together with the retainer shaft and defining at least one switch-off point, at least one sensor device supported in the housing for defining the switch-off point, and an adjustment mechanism for adjusting the switch-off point. In known devices of this type, the accurate and rapid adjustment of the switch-off point is difficult. According to the invention the adjustment mechanism is provided within the housing between the switching sleeve and the retainer shaft.Type: GrantFiled: July 22, 1987Date of Patent: August 15, 1989Assignee: Weber-Schraubautomaten GmbH & Co., K.G.Inventor: Karl-Heinz Weber
