摘要： A method and component for repairing broken conduit ends extending from concrete foundations is disclosed. The method and component for repairing broken conduit ends of this invention eliminates the need to break up the concrete foundation around the broken conduit end. The specialized repair components include a reaming bit for milling out and turning down the inside wall of the broken conduit end and repair coupling for joining a new section of conduit to the broken conduit end. The reaming bit is designed to be used with any conventional handheld power drill. The reaming bit mills out the inside of the broken conduit end so that the repair coupling can be inserted into the broken conduit end. With the coupling fitted into the broken conduit end, a new section of conduit can be connected completing the repair. Because the coupling is inserted into the broken end of the conduit instead of over it, the concrete foundation around the conduit does not have to be disturbed providing a structurally more secure repair.

摘要： The machining head for machining valve seats comprises a driving system, a housing, a carriage feed assembly, a cutting tip mounted on the carriage, and a counterweight assembly. The driving system rotates a machining head on a spindle axis, and further provides independent vertical translation of each of a driving arbor and a spindle, both of which are independent of the rotation of the spindle. The carriage has both forward and backward feed capability for moving the cutting tip radially inward or outward as it cuts. Vertical movement of the arbor is converted into force for moving the carriage by a cantilever pivoting around a fixed point. The counterweight assembly, linked to the arbor by a second cantilever, counterbalances the shift in weight caused by the movement of the carriage in order to maintain dynamic balancing as the machining head rotates.

摘要： This invention is a portable pneumatic cutter tool for cutting countersinks into a workpiece 17 having pre-drilled holes 15. When pressure is applied, a piston return cylinder 57 and a feed rate cylinder 79 are also pressurized, which sets a body piston 72 and spindle piston 80 reacts against a spindle bar 82 which holds nose 94 in its outer-most limit position. A pistol grip drill 44 drives a geared belt 34 to cut the countersink after actuation by trigger 45. A flare tube shaft 14 expands a multiple finger and pad arrangement of a collet 12 to provide clamp-up on the back side of workpiece 17. Clamp-up on the front side of workpiece 17 is provided by pneumnatic pressure and solid mechanical stops 16. The countersink cutter 18 advances into workpiece 17, reaching its depth, and returns automatically to its start position.

摘要： A valve seat refitting apparatus. A cylindrical main body portion has a longitudinal bore which receives a centering guide. Longitudinal slots around the outer periphery of the main body portion receive cutting blades rigidly attached to cutting blade support. Radial and longitudinal positioning screws serve to position the supports and cutting blades to refit a variety of valve seats. Set screws lock the blade supports in the desired position. A bushing removably attached to the centering guide also allows the centering guide to be adapted to fit different size valve seats.

摘要： A portable milling tool for milling pipes, tubes, cylinders, and the like has an expandable sleeve at one end thereof for securing and centering the tool to a workpiece. An adjustable in-line rod connects the sleeve to the tool and permits the sleeve to release or secure the workpiece. An in-line shaft moves the tool into or out of engagement with the workpiece. The tool also is of compact design allowing it to be used in on-site situations wherein tool size is a problem as in milling boiler tubes.

摘要： A portable horizontal drill press for drilling holes in the surfaces of highway vehicles and construction type equipment including a T-shaped base support beam which is mounted on swivel type wheels with low clearance provided to minimize tipping. A drill support column having a slidable mounting platform for an industrial type drill motor is mounted at one end of the beam support structure. The drill motor platform includes a hand wheel and lead screw combination which is used for feeding the drill motor into the work. The height of the drill motor platform can be adjusted either by a rack and pinion gear provided on a one-piece solid column or the column can be provided in several telescoping sections which can also combine a rack and pinion gear for the upper section of the column. A similar height elevating and positioning arrangement can be provided for a center support column provided at the opposite end of the base support beam. The center support column can be longitudinally moved with respect to the drill platform along the elongated support beam for adjusting the position of the drill center column in relation to the drill motor. A drill center rod is provided on the center support column and adjusted to contact that opposite side of the object so as to back-up the drill during the drilling process. In one embodiment the drill support column has a pivoting socket arrangement whereby the column can be laid down parallel to the support beam to allow the center column to be moved under an object having low clearance and then erected for positioning the drill center opposite the location of the area to be drilled.

摘要： A rotary reaming and counterboring tool includes a central body (28), a proximal mounting flange (30) and a distal end (36), longitudinal lands (44) and straight flutes (40) between the lands. The lands overhang the distal end of the cutter body and are provided with forward facing (relative to the cutting direction) radial reaming cutting edges (64) at the distal ends of the lands and counterboring radial cutting edges (68) at radially stepped portions of the lands. The lands are generally trapezoidal in cross section and a central bore (56) extends through the central body for accommodating a mandrel that supports the cutting tool and its driving head during operation of the tool to perform a reaming and counterboring operation.
