20150330771 | DIGITAL MEASUREMENT UNIT FOR FISH TAPE DEVICE OR DUCT RODDING DEVICE - An assembly includes a fish tape device or a duct rodding device having digital measurement unit attached thereto. A tape is housed in the fish tape device or a duct rodding device and is paid out of the device. The digital measurement unit includes an optical sensor which is positioned proximate to the tape. As the tape is passed by the optical sensor, the optical sensor uses digital image correlation to take successive images of the tape to determine a length measurement of tape that has passed by the optical sensor. | 11-19-2015 |
20150139774 | ROTARY CHUCK - A rotary chuck includes a clamp assembly, a first drive mechanism for operating the clamp assembly to clamp an associated workpiece, a frame rotationally fixed to the clamp assembly, and a second drive mechanism for rotating the frame and the clamp assembly. The second drive mechanism can rotate the frame and the clamp assembly around 360 degrees. A pair of alignment springs are engaged with a mounting plate upon which the second drive mechanism is mounted. The mounting plate can pivot relative to a stable surface to which it is mounted, and the springs limit the pivotal movement. Each first and second drive mechanism includes a motor, and are connected to a microprocessor for operation of the respective motor. | 05-21-2015 |
20150071721 | ARBOR ASSEMBLY FOR USE WITH A CUTTING DEVICE, SUCH AS A CUTTER OR HOLE SAW - An assembly is provided for forming holes in a workpiece. The assembly includes an arbor, a pin sleeve and a cutting device. The arbor has a nose having at least one threaded portion and at least one unthreaded portions on an external surface thereof. The arbor also has at least one pin passageway extending therethrough. The pin sleeve has at least one pin extending from a main body. The arbor extends through the pin sleeve. The cutting device has a back plate and a plurality of teeth extending therefrom. The back plate has a passageway defined by a wall with at least one threaded portion and at least one unthreaded portion. The at least one threaded portion of the cutting device is capable of engaging with the at least one threaded portion of the nose, and the at least one pin of the pin sleeve is capable of engagement with the at least one pin passageway of the arbor to secure the components together. | 03-12-2015 |
20140318344 | DIE WITH PROFILED BASE WALL AND ITS ASSOCIATED PUNCH - An assembly includes a die and a punch which cut a hole in a workpiece. The die has a base wall having outer and inner surfaces and a passageway extending therethrough, and a wall extending from the base wall. The inner surface of the base wall has at least one portion which is angled relative to a central axis of the die. The punch includes a body having a bore therethrough, a leading edge on the body which is capable of piercing and cutting a workpiece, and cutting edges on the body for cutting a hole in the workpiece. The leading edge has inclined surfaces between the bore and the piercing points which engage with the portion of the inner surface of the die. | 10-30-2014 |
20140270673 | CABLE ROLLER - A cable roller for use in positioning a cable relative to a cable tray or relative to a ceiling of a building includes a mounting channel, a support assembly attached thereto which is moveable relative to the mounting channel, and at least one roller attached to the support assembly for allowing the cable to roll thereover. The support assembly can be moved from a closed position to an open position to allow for the easy removal of the cable from the cable roller. | 09-18-2014 |
20140035557 | NON-CONTACT, HAND-HELD VOLTAGE DETECTOR - A non-contact, hand-held voltage detector is used to determine if AC voltage is present in a tamper-resistant receptacle. The voltage detector includes a pair of pins to open both shutters of the tamper-resistant receptacle. | 02-06-2014 |
20130145916 | SLEEVE FOR A PUNCH ASSEMBLY - A punch assembly includes a punch, a sleeve, a draw stud and a die. The sleeve adds rigidity to the draw stud, thereby reducing elastic deflection of the draw stud, reducing bending moment on the draw stud, reducing punching force, and extending the punch, draw stud and die fatigue life. The sleeve also aids in axial alignment of the punch, die and workpiece with a pilot hole drilled through a workpiece. | 06-13-2013 |
20130145915 | PUNCH PROFILE FOR A PUNCH, AND THE ASSEMBLY IN WHICH THE PUNCH IS USED - A punch assembly includes a punch, a sleeve, a draw stud and a die. The punch has a punch profile which provides a cutting edge that has a uniform “sharpness” along entire perimeter of the punch. The punch assembly provides additional punch-to-die clearance over what was done in the prior art. This reduces excessive punching forces which result from axial deflection of the draw stud and “tipping” of a large diameter punch as the draw stud deflects under a load. | 06-13-2013 |
20130081843 | Hydraulically Operated Tool Including A Bypass Assembly - A bypass assembly varies the hydraulic motor revolutions per minute (rpm) of a hydraulically driven tool, such as a wrench or a drill. This controls the torque of a driven mechanical mechanism, such as used on an impact wrench. The tool includes a body having a supply channel capable of being connected a source of fluid, a bypass spool channel in fluid communication with the supply channel, and a return channel in fluid communication with the bypass spool channel via a port and in fluid communication with the source. A bypass spool seats in the bypass spool channel. The bypass spool can be rotated to three discrete positions within the bypass spool channel to provide three different settings of revolutions per minute (rpm) of the gear motor. | 04-04-2013 |
20130081839 | HYDRAULICALLY OPERATED TOOL WITH RELIEF VALVE ASSEMBLY - A relief valve assembly limits the maximum torque of a gear motor of a hydraulically driven tool. The relief valve assembly dumps flow to a return channel to return hydraulic fluid to the supply when the relief valve assembly is activated. The relief valve assembly is placed in the channel of a directional valve spool, and varies its pressure setting depending upon spool position. This is useful to vary the pressure settings of a hydraulic motor in different directions. | 04-04-2013 |
20130081838 | Handle For A Hydraulically Driven Tool With Heat Transmission Reducing Properties - A handle for a hydraulically driven tool is provided reduces the amount of heat transmitted to the user of the tool as a result of the high temperature fluid flowing through the inner body of the handle. The inner body is formed of a heat transmissive material which has at least one channel through which the fluid flows. The handle has a number of properties which reduces heat transmission to the user, including standoffs, ribs and fastener receiving extensions. | 04-04-2013 |
20100297870 | RJ MODULAR CONNECTOR - An RJ modular connector is provided that has wire channels that slope downward and end at openings in the bottom of the connector through which the stripped wires extend. In use, the outer jacket insulation is removed from an end portion of the cable, leaving lengths of exposed wires. The length of the exposed wire is unimportant. The wires are arranged in an essentially flat configuration and inserted longitudinally into the connector and then directed downward by the downward slope of the channels, so that the distal ends of the respective wires extend through the bottom of the connector. The protruding wire ends are then compared with a standard to confirm the correct color identification pattern for them and corresponding wire position. After the comparison is made, the protruding wire ends are crimped/secured and sheared off. Conductive contact blades are inserted, and pierce the wires. | 11-25-2010 |
20090203252 | RJ MODULAR CONNECTOR - An RJ modular connector is provided that has wire channels that slope upward and end at openings in the top of the connector through which the stripped wires extend. In use, the outer jacket insulation is removed from an end portion of the cable, leaving lengths of exposed wires. The length of the exposed wire is unimportant. The wires are arranged in an essentially flat configuration and inserted longitudinally into the connector and then directed upward by the upward slope of the channels, so that the distal ends of the respective wires extend through the top of the connector.
