摘要： A handle-connecting assemby for hand-held machine tools comprises a wire element having a loop engaging a tool-supporting projection of the tool and a hollow member adapted to receive the ends of the wire element. The ends of the wire element are rigidly connected to a head of a bolt, the end threaded portion of which is threaded into a handle. The wire element connecting the tool-supporting projection to the handle provides for sufficient flexibility of such connection thereby the handle may positioned at an acute angle to the axis of elongation of the projection.

摘要： A rock drill comprises a shaft having a leading and a trailing end, a shank connected to the trailing end, and a drill head connected to the leading end of the shaft. Means for transporting drilling from the leading end toward the trailing end of the shaft are provided which include at least one channel extending parallel to the shaft from the drill head toward the shank. A shell coaxially surrounds the shaft and bounds the channel, which shell has an open front end adjacent the drill head, a closed rear end facing the shank and at least one transverse bore adjacent the rear end of the shaft and open at the outer surface of the shell.

摘要： A portable power tool wherein the housing contains a pump, a tank for a supply of oil for the pump, an electric motor for the pump and one or more hydraulic motors which receive pressurized oil from the pump and impart movements to a rotary and/or reciprocable tool, such as a rock drill or chisel. The motor which imparts reciprocatory movements to the tool is a cylinder and piston unit whose piston is rigid with a piston rod serving to strike against the tool whenever the piston performs a forward stroke. A valve assembly having a motor-driven rotary spool controls the flow of pressurized fluid to and the outflow of spent fluid from the cylinder. A spring brakes the rearward movements of the piston, and a bladder type accumulator is connected with the outlet of the pump. The tank is cooled by currents of air which are induced by a blower on the output shaft of the electric motor and which cool the electric motor before they reach cooling fins provided at the outer side of the tank.

摘要： A hand-guided power tool comprises a housing and a base plate mounted below the housing. The base plate is adapted to be juxtaposed with an object which has material to be removed therefrom. A tool element such as a reciprocable cutting blade extends through a slot formed in the base plate and is operative for removing material from the object with concomitant production of undesirable particulate material in the circumambient region of the element. A channel member is also mounted below the housing but at a distance from the base plate to thereby form a suction channel which is in communication with the circumambient region of the tool element and which is operative for removing and guiding the particulate material from the tool element.
