  • Patent number: 7108077
    Abstract: 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.

  • Patent number: 6249982
    Abstract: A manual planing machine, has a planer shaft having at least one longitudinal slot, an elongated flat planer knife clamped in a detachable manner in the and formed as a dual-cutting mini reversible tip with at least one cutter and with a back groove extending parallel to the cutter and with a holding rib on a side of the longitudinal slot to prevent an intentional detachment from the planer shaft, the planer knife carrying only one the cutter, extending in a corrugated manner in such a way that troughs of the cutter lie on a common first straight line having the same spacing relative to the back groove as a cutter of a mini reversible tip, while its crest lie on a common second straight line which extends 0.5-1.5 mm radially above the first straight line, the planar knife carrying a contact edge which is right-tangled and is flattened relative to a back, instead of another cutter at a side located opposite from the at least one cutter for support at the radial stop of the planar shaft.

  • Patent number: 6131627
    Abstract: A planer (10), in particular a hand held planer for machining wood, with a planer housing (12), which includes a planer shaft (20), supported rotatably in at least one direction with an outer contour (23), which in a longitudinal groove (46) has at least one planer blade (21), which is braced on a centrifugal wedge (56) that can be prestressed with a spring (54) or the like can be produced more simply and economically in that the centrifugal wedge (56) is fastened to the planer shaft (20), elastically movably relative to it, in captive fashion solely by the spring (54), in particular being removable without destruction, and substantially without touching the planer shaft (20).

  • Patent number: 6092573
    Abstract: The plane head for the hand-held planing machine includes a cylindrical base body (11) made from a group of identical stamped sheets (18) arranged axially next to each other and each provided with a punched hole (150) so as to form a base body cavity (15); a planing knife (14) protruding radially beyond an outer surface of the base body (11) from a longitudinal groove (13) and fixed therein by a form-fitting connection or form-locking connection so that the planing knife cannot be radially dislodged from the base body; and a chuck wedge (16) received in the base body cavity (15) so that the planing knife (14) is clamped in the base body (11) by centrifugal force during rotation of the plane head.

  • Patent number: 5414935
    Abstract: 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.

  • Patent number: 4601104
    Abstract: 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.
