摘要: Agricultural discs are given a hardened annular run by providing a differential heat treatment. During the heat treatment step an annular ring of heat conductive material is placed on the outer periphery of the disc. Thus ensures that the outer edge is of greater hardness than the central portion of the disc.

摘要: A cast rail clip support of the kind used in concrete railway sleepers wherein one portion (17) of the rail clip is held in the rail clip support (19) and a second portion of the clip (16) bears down on the rail flange. The recess (26) of the rail clip support has slots (32) shaped to accommodate in a neat fit the base portion 17 of the rail clip. The clip when held in the recess 16 abuts the lower contact surface 33 and the end of the base portion 17 abuts the upper contact surface 34 which is inclined 3.degree. above the horizontal. This arrangement presents the clip from being accidentally knocked from its position in the rail clip support.

摘要: An implement for agricultural machines which is attachable to a tine of such a machine. The earth engaging portion includes steeply inclined side faces 11 and an inclined point 10 with a protrusion 14 which assists in directing work flow. The relatively flat portion 12 lies above the side faces 11 between them and the shaft portion 8 which is attachable to the tine. These implements are formed from conventional implement blanks and the height of the side faces is the same as that of conventional implements but the angle of inclination is greater.

摘要: Apparatus for removing elastic rail fasteners of the kind that are applied transversely of the rail. The apparatus removes two fasteners simultaneously from a rail seat. The apparatus comprises a carrier frame (10) having a pair of opposed abutment plates (14 and 15) which move arcuately parallel to the rail (12). Associated with each plate (14 or 15) is an extraction lever (26a and 26b) which moves arcuately transverse to the rail. The abutment plates align the apparatus with the fastener (40), compress the arms (44) of the fastener (40) and the extraction levers (26a and 26b) pull the fasteners (40) from the rail seat.

摘要: Apparatus for applying elastic rail fasteners to a rail seat in which the fasteners are applied in a direction at right angles to the rail. A carriage supports a pivoted frame which can be rotated to align with a rail tie. Each end of the frame carries a pair of dependent arms and each pair is moved hydraulically. Abutment faces on the ends of the dependent arms contact the rail fasteners and the simultaneous contraction of each pair results in the fitting of four rail fasteners in one application. Rail tie position sensors are provided adjacent the abutment faces for correctly aligning the frame with the rail tie.
