Abstract: A method of forming a recess in a work, a work in which the recess is to be formed is a material that can be cut. A cutting tool for forming the recess is held by a moving apparatus at a prescribed angle relative to the work. The cutting tool is moved in a carving direction for carving the work at the prescribed angle, and a thin cutting fin is vertically formed. Then, the cutting tool is moved in the horizontal direction, and the cutting fin is cut and separated from the work. The fin-forming step and the cutting step are repeatedly performed in sequence, whereby a recess having a prescribed depth d and area is formed in the work.

Abstract: An external weld bead is removed and processed from a welded pipe traveling in a downstream direction. The weld bead is separated from the pipe, guided through a guide passage having an inlet and an outlet, and cut into pieces at the guide passage outlet in a location above the pipe.

Abstract: Methods of producing a pipe include curling a skelp into a cylindrical shape by bringing laterally opposed edges of the skelp together to form a seam, butt welding the seam to define the pipe downstream of the skelp, thereby leaving a radially inwardly extending weld bead. The weld bead is deburred off the pipe according to a depth of cut of a cutting tool. The depth of cut may be adjusted during deburring, and/or rotation of the cutting tool may be adjusted during deburring. The methods may be carried out using one or both of an adjustment device carried by a housing to pivot an adjustment member for adjustment of an upstream guide to adjust a depth of cut of the cutting tool into the weld bead, or an adjustment device carried by the housing and coupled to the cutting tool to rotate the cutting tool during deburring.

Abstract: A hand planer comprises a housing, a planer head supported in the housing, a motor driving the planer head, a fan blower connected with the motor for generating a flow of air for moving chips, a chip ejector, two air guidance ducts through which the flow of air is guided from the fan blower to the chip ejector, a chip conveying duct having a chip discharge opening such that planed chips exit the chip conveying duct through the chip discharge opening, the chip ejector accommodating both the chips and the flow of air, and guides for guiding the flow of air in a switchable manner to the chip conveying duct via one of the two air guidance ducts. Therefore the problem of ejecting the chips in a preselected direction with extreme precision and high efficiency is met.

Abstract: A railroad tie adzer has a cutter head and means for rotating the cutter head to surface the tie plate area of a tie. A cutter guard extends peripherally about the path of rotation of the cutter head, and there is a vacuum duct opening into the cutter guard to remove debris during the adzing operation. A volute deflector is positioned within the cutter guard and extends partially about and outside of the path of movement of the cutter head. The volute deflector extends from adjacent the vacuum duct circumferentially in the direction of cutter head movement. There is an inclined ramp adjacent the entrance to the vacuum duct to direct debris from adzing, moving in a volute or spiral pattern, as defined by the deflector, into the vacuum duct. The vacuum duct is connected to a fan which in turn is connected to a separator from which the separated dust and debris are discharged away from the adzer.

Abstract: Rail heads are planed with a mobile machine moving continuously along a track and comprising a frame and a rail planing tool mounting linked to the frame. The mounting is adjusted vertically relative to the running surface of the rail head and pressed thereagainst, and guided along the rail head by a guide roller laterally guiding the mounting along a selected side of the rail head and two additional guide rollers vertically guiding the mounting along the running surface of the rail head. A tool head including a tool holder is mounted on the mounting for displacement relative thereto and a rail planing tool is replaceably mounted in the tool holder and detachably carries a cutting blade having a cutting edge for planing chips or shavings off the rail head by the forward thrust of the machine. A pick-up magnet removes the chips.

Abstract: A billet scalper including a die assembly with a scalping die, a pressing mechanism with a stem member in axial alignment with the scalping die for pressing a billet thereinto, and a chip ejector located around the circumference of the scalping die and movable axially back and forth beyond a free end face of the scalping die to remove chips therefrom. The die assembly including the scalping die is movable between a position at the center of the scalper and an outer receded position to permit easy maintenance and service of the die assembly including replacements and cleaning of scalping dies. In a preferred form, the scalper is constructed integrally with an extrusion press to perform the billet scalping operation in timed relation with the extruding operation to shorten the time of press cycle.

Abstract: Conditioning apparatus for a cast metal bar is disclosed which comprises a conveyor having a plurality of blocks each of which has a surface depression defining a bar support and guide channel, an endless support to which the blocks are mounted in an endless series with the block bar support and guide channels tandemly aligned, and means for driving the endless support and series of blocks along a circuitous path that extends generally linearly through a bar conditioning station. The apparatus also comprises hold down roller means located at the bar conditioning station for holding a cast metal bar in the bar support and guide channels of blocks being driven through the bar condition station; means for trimming a cast metal bar supported and guided in the bar support and guide channels of blocks at the bar conditioning station, and means for flushing bar trimmings from the bar supported on the conveyor at the conditioning station.
