Patent number: 7108077Abstract: A power tool (10) with a housing (12) which accommodates a driven shaft (32) for holding a material-removing tool (40) and which sets the driven shaft into rotary oscillating motion capable of being produced by an eccentric (22) rotating around an axis extending at a right angle to the driven shaft (32), the eccentric engaging in a connecting element coupled with the driven shaft (32), is usable in a more diverse manner because the rotary oscillating motion of the driven shaft (32) and, therefore, the tool (40), is adjustable with a certain travel and is therefore adaptable to special applications.Type: GrantFiled: November 30, 2004Date of Patent: September 19, 2006Assignee: Robert Bosch GmbHInventor: Adolf Zaiser

Patent number: 5414935Abstract: A motor driven hand power tool has a saw including a saw blade, a separating tool formed as a saw blade movable about a tilting axis extending parallel to a cutting line of sight and fixable in each turning position relative to a workpiece which is subdivided by a cutting joint into a product-side and a refuse-side with product and refuse-side cutting edges, a base plate over which the saw blade is positioned. The saw blade is arranged so that the tilting axis extends at a distance under a lower side of the base plate, and the distance is dimensioned so that the tilting axis in a working position of the power tool is located under an upper surface of the workpiece in an interior of the workpiece.Type: GrantFiled: December 1, 1993Date of Patent: May 16, 1995Assignee: Robert Bosch GmbHInventors: Karl-Heinz Braunbach, Adolf Zaiser, Hans Bloechle, Thomas Demuth

Patent number: 4601104Abstract: In order to achieve an improved chip and shaving ejection in a portable per, a small portion of the motor cooling air stream is diverted and directed through an air passage into a chip ejection channel. The volume flow of this chip ejection air stream may be controlled by a control slider gate to suit various operating conditions. The chip ejection air stream also serves to cool the drive belt and planing head. The diverted air flow keeps the chips in a sufficiently loose state to assure an effective, clog-free ejection of chips. Furthermore, a deflection flap is used in the chip ejection channel to eject the chips to either side of the tool as desired.Type: GrantFiled: February 19, 1985Date of Patent: July 22, 1986Assignee: Karl M.
