Patent number: 5596810Abstract: A hand machine tool operated with two hands has a machine housing composed of insulating synthetic plastic shells, a fixed, web-shaped main handle formed as a part of the machine housing, an auxiliary handle, a drive including a motor and a transmission, at least one inner housing accommodating the motor and the transmission and surrounded by the synthetic plastic shells, and a tool driven by the drive. The handles, the machine housing, the inner housing and the tool are arranged so that forces applied to at least one of the handles are withdrawn from the machine housing by transferring the forces by the main handle directly to the inner housing without deforming the machine housing and then transferring the forces from the inner housing to the tool.Type: GrantFiled: March 7, 1994Date of Patent: January 28, 1997Assignee: Robert Bosch GmbHInventors: Werner Neubert, Joachim Schadow, Joachim Mueller, Manfred-Otto Staebler, Manfred Dohr, Heinz Warkentin

Patent number: 5473820Abstract: A power-operated sword saw comprises a plate-shaped sword having a lower region with a guiding groove, two saw blades reciprocatingly movable in opposite directions parallel to one another and each having a front saw blade tip and an opposite clamping end. The saw blades have a toothed side provided with a plurality of teeth and an opposite saw blade back guided in the guiding groove of the sword. A drive is coupled with the clamping ends of the saw blades through a clamping unit. The saw blades are jointly coupled with the clamping unit and released from the clamping unit by a blocking element which blocks the clamping ends in a coupling position and release the clamping ends in a contact-free manner.Type: GrantFiled: March 7, 1994Date of Patent: December 12, 1995Assignee: Robert Bosch GmbHInventors: Werner Neubert, Joachim Schadow, Joachim Mueller, Manfred-Otto Staebler, Manfred Dohr, Heinz Warkentin

Patent number: 5398414Abstract: An electric hand saw has a stationary sword having a lower side, a reciprocatable saw blade received in the lower side of the sword and having a rear end portion, a machine housing having a transmission outlet in which the rear end portion of the saw blade is received. The machine housing has a longitudinal slot located under the rear end portion of the saw blade. A suction passage is mounted on the lower side of the machine housing and has a sucking-in opening extending from the front end side of the suction passage to the longitudinal slot of the machine housing located under the rear end portion of the saw blade.Type: GrantFiled: January 10, 1994Date of Patent: March 21, 1995Assignee: Robert Bosch GmbHInventors: Werner Neubert, Joachim Schadow, Joachim Mueller, Manfred-Otto Staebler, Manfred Dohr, Herbert Faerber, Heinz Warkentin

Patent number: 4506711Abstract: A cutting roller for a hand-operated planing tool includes an elongated primary member and two pressure members, symmetrically surrounding the primary member at two side faces thereof. A plurality of planing knives are clamped between the pressure members and the primary member. The cutting roller is provided with fit elements which are attached to the primary member and fit in the recesses formed in the pressure members. During the assembly the fit members are aligned with the bearings of the cutting roller in the housing of the planing tool and then are attached to the primary member. The planing knives thereby are always aligned in the correct position with respect to the primary member. The pressure members are secured to the primary member by bolts.Type: GrantFiled: September 14, 1983Date of Patent: March 26, 1985Assignee: Robert Bosch GmbHInventors: Gerhard Armbruster, Werner Neubert, Gunter Schaal
