A detachable tool body is connected to the mandrel by means of a universal type coupling. The mating end of the drive shaft is constructed with U-shaped element having a pair of arms extending axially towards the tool body. The inner surfaces of the arms form a partially cylindrical seat. A similar U-shaped element having a pair of similar arms is constructed on the tool body with basically a mirror image profile relative to the drive shaft element. In the assembled position the mated arms define an inner bearing chamber (seat) having dual cylindrical surfaces with transverse axes. A barrel is constructed, which is shaped to nest in the seat formed by the mated pair of U-shaped elements and acts as a bearing which allows dual axes of motion. The adjustment rod of the abrasive element adjustment mechanism extends from the drive shaft through a bore in the barrel and into the tool body. |

An automatic welding machine includes a welding torch attached to a torch transporting carriage clamped to a guide rail by at least one pair of opposed wheels in contact with opposite sides of the rail. A drive source, connected to an axle of one of the wheels drives the carriage along with rail. At least one of the wheels which roll the carriage along the rail is of elastic material, such as rubber or synthetic resin, having a high coefficient of friction to prevent unwanted movement of the carriage along the rail when the driving power from the drive source is removed. |

A hone stop assembly for use with a honing tool in reconditioning the cylinder bores of an internal combustion engine block. The assembly includes a frame mountable to an engine block, a disk-shaped hone stop, and suitable adjustable connections from the hone stop to the frame to allow the stop to be selectively positioned adjacent to an end of a cylinder bore. A honing tool inserted from the other end of the cylinder bore will contact the hone stop rather than any engine castings adjacent to the end of the cylinder, preventing damage to the honing stones and facilitating accurate reconditioning of the cylinder walls while reducing the tendency of the mechanic to taper the cylinder walls. |

An apparatus for holding of workpieces with at least one vertical bore, particularly for holding a connecting rod, for a honing operation. The apparatus includes two workpiece receiving plates between which the workpiece is insertable with horizontal and vertical play. The workpiece receiving plates have an opening for receiving the honing tool. A holding device is provided and is fixable relative to a workpiece receiving plate; vertically the holding device engages the workpiece free of play at a slight engagement pressure. The holding device is freely movable toward the workpiece in a first direction, and is immovable in the opposite direction. The honing device comprises at least one angle lever, which is tiltable or pivotally journalled relative to a workpiece receiving plate, has one arm engaging against the workpiece, and has the other arm connected with a device which restrains the angle lever in the release or loosening direction. |

PROBLEM TO BE SOLVED: To provide a drilling machine for a brittle material for a drill to be detachably fixed to a drill rod surely by a lock coupling part and capable of a transmitting a drilling torque. SOLUTION: For the purpose of relatively accurate positioning, a drill head (2) has a conical shape part (10), which is engaged at its center within a corresponding receiving port (11) of the drill rod (3) in an operating state as shown. As an axial looseness preventing means, a restricting member (15) constituted as a hollow nut is provided to be engaged with threads (16) of the head having a reverse pitch and threads (17) of the rod. The head and the rod can be simply clamped to each other or separated from each other by rotating the member. The coupling part enclosed by the member is simultaneously optimally protected against an external influence. Accordingly, a drilling machine (1) can accurately drill without excess wear or complicate handling. |
