Abstract: An example hand wrench is provided. The hand wrench may include a handle (15) having a handle opening (12), and an orbital member (24) received within the handle opening. The orbital member may be configured to move orbitally about a point axis. The hand ratchet wrench may further include a driver affixed to the orbital member. The driver may be configured to receive a socket that interfaces with a fastener to turn the fastener.
Abstract: A tapping device is configured to be used within a drill press or lathe or other device capable of holding a cylindrical object. The tapping device has an upper projection for being axially fixed in, for example, a drill press. The remainder of the body of the tapping device is rotatable with respect to the upper projection and includes side handles for providing handy mechanical advantage to the turning of the tapping device body. The end of the body opposite the upper projection includes a chuck for holding a typical tapping tool. The projection is connected to an internal shaft which engages the body of the tapping tool and is spring biased to draw the projection and internal shaft within the body of the tapping tool. Conversely, when the tapping tool is supported in, as an example, a drill press chuck, such spring urging acts to lift the body of the tapping tool in the direction of the projection.
Abstract: A hand tool can remove burrs from an aperture in a workpiece. The tool has a hollow handle and a shaft rotatably mounted in the handle to reciprocate axially therein. The tool has a thruster for urging the shaft to extend axially. A rider is mounted in the handle for engaging and rotating the shaft as it extends axially from the handle. This rider can allow axial retraction of the shaft into the handle without rotation. A deburring bit (e.g. a countersink bit) is mounted at an outer end of the shaft. Thus the bit turns when the shaft extends as the handle withdraws from the workpiece.
Abstract: A tool couple which is used with a manually-operated threading die to aid in cutting the initial threads on a pipe or bolt. The device is used to force the anterior cutting edge of the die firmly against the outer, unthreaded surface of the workpiece at the outset of a threading operation. The die is kept wedged, as the initial threads are being cut, between the workpiece and a rotatable member of the tool couple so that the die cannot slip backward toward the leading edge of the workpiece. To keep the die so wedged, the rotatable member is advanced in the direction of the end of the workpiece at approximately the same rate as the die is moved along the longitudinal axis of the workpiece. By maintaining the anterior cutting edge of the die in juxtaposition to the advancing edge of the thread, the device prevents a chamfering of the leading edge of the workpiece as the threading die is turned.
Abstract: An apparatus and process for restricting fluid flow in a pipeline by inflation of an expandable flexible sleeve which is attached to a plug having a through hole for the inflation fluid. Several embodiments of flow restrictor cartridges are disclosed including cartridges having retainer arms which pivot outwardly against the interior wall of the pipeline restricting the axial expansion of the flexible sleeve upon inflation, thereby providing higher pressurization of the flexible sleeve for use in pipelines of pressures up to about 100 psi. The flow restrictor cartridges may be used in combination with an insertion assembly and by placement of a boring tip on the flow restrictor cartridge may be used with a disclosed cartridge insertion tool providing reduced loss of pipeline contents upon boring a hole in the pipeline followed by insertion and inflation of the flexible sleeve for restricting fluid flow in the pipe.
