| 20080276768 | MANUAL CLUTCH ASSEMBLY AND SERVICE TOOL - An assembly tool for installing a clutch pressure plate and clutch housing of a manual clutch on the flywheel of an engine includes a bell shaped housing which receives and pivotally supports a plurality of fingers having outwardly directed claws. A coaxial cylindrical portion of the bell shaped housing includes male threads which receive a complementarily threaded collar which may be rotated to engage, radially extend and retract the fingers. Internal threads in the cylindrical portion of the housing receive a complementarily threaded portion of a push rod. The push rod includes a thrust bearing at an end that engages the fingers of the pressure plate and may be rotated to engage, retract and extend the pressure plate. A method of clutch housing installation utilizing the tool is also disclosed. | 11-13-2008 |
| 20090049961 | TORQUE RELEASING CLUTCH FOR A SCREW DRIVER BLADE - A torque releasing clutch for a screw driver blade is installed in a connect rod, including a spring, ball holes for fitting steel balls, and a washer respectively in the holes to restrict the spring and the steel balls within the groove of the clutch so that the clutch moves forward and backward regularly. When a screw is driven in an object for a preset depth, the clutch may push forward the screw driver blade so that the torque-releasing steel balls may release the screw driver blade in time. Then, even if the screw driver should still have some torque, it might only rotate the connect rod idly, keeping the driver blade immovable. Thus the remaining torque might not damage the blade slot of the screw, in addition to avoiding the remaining torque returning to a user of the screw driver and harming the user. | 02-26-2009 |

| 20100224038 | SCREW GUIDE - A fastener guide includes a shaft having a first end for transferring torque to a fastener and a second end for receiving a torque from an external source, the shaft including a threaded portion and an axial groove extending axially along the threaded portion. The fastener guide also includes a sleeve slidable axially with respect to the shaft, the sleeve having a first end proximate the first end of the shaft and a second end proximate the second end of the shaft, and a depth-adjustment ring having a threaded inner surface for engaging the threaded portion of the sleeve and a detent ring for selectively engaging the axial groove. | 09-09-2010 |
| 20110000344 | DEPTH GAUGE AND ADJUSTMENT TOOL FOR ADJUSTABLE FASTENER RECEPTACLES AND METHOD - A depth gauge and adjustment tool ( | 01-06-2011 |
| 20120055294 | OILFIELD TUBULAR SPIN-IN AND SPIN-OUT DETECTION FOR MAKING-UP AND BREAKING-OUT TUBULAR STRINGS - Spin-in and spin-out apparatus and methods are presented wherein an oilfield tubular spinner used in combination with a wrench detects the shouldering-up of tubulars during make-up and tubular thread disengagement during break-out. Sensors are employed to quantify measurables indicative of shouldering-up and thread disengagement, the measurables being used to shutdown spin-in and spin-out operations. Thresholds are employed to detect measurable values of interest. Timers may be employed to monitor and control the spin-in and spin-out operations. | 03-08-2012 |
| 20130112049 | Torque Tool Cycle Counter - A tool for applying torque to workpieces, having a sensor adapted to detect a rotational parameter measured during application of torque to each of the workpieces, wherein the rotational parameter includes an amount of angular rotation applied to each of the workpieces an/or an amount of torque applied to each of the workpieces, a memory operably coupled to the sensor and including a stored number of cycles, wherein the sensor is adapted to add a cycle count to the stored number of cycles each time that the rotational parameter meets a parameter threshold to indicate a number of the workpieces in which the rotational parameter meets the parameter threshold, and an indicator adapted to indicate to a user when the parameter threshold has been met for one of the workpieces and to indicate the stored number of cycles. | 05-09-2013 |
| 20130139657 | HIGH SPEED, HIGH TORQUE SCREW FASTENERS AND DRIVE SYSTEMS - A fastener system including a threaded fastener having a slot formed in the fastener head. Facets are formed in the slot walls, each facet having an angle of less than ninety degrees with respect to the base of the slot such that the slot has a variable width and at least a portion of the width of the base is greater than the width of the opening of the slot. A driver bit includes a blade configured to be inserted into the slot of the fastener. At least a portion of the free end of the blade has an increased width such that the blade is locked within the slot of the fastener when torque is applied to the driver bit. | 06-06-2013 |
| 20130340576 | Screw Driving Device - A screw driving device is provided which can counter-sink a screw at angles off of normal from a workpiece. The device includes a shank held in contact with a screw bit to drive the tip when a plurality of balls are held in contact between a screw bit head and a sleeve surrounding the shank and to disengage the shank from the bit when the screw is at a desired counter-sunk depth. The disengagement of the shank from the screw bit is provided by permitting the plurality of balls to slide out of contact between the rotating shank and bit to thus disengage the shank from the screw bit. | 12-26-2013 |
| 20150090077 | HAND TOOL CAPABLE OF INDICATING REVOLUTION NUMBER - A hand tool includes a central shaft extending along an axis and having a threaded section, a tool head sleeved rotatably on the central shaft, a pressing block sleeved movably on the central shaft, an adjusting member threaded to the threaded section of the central shaft and rotatable to move the pressing block on the central shaft, and an indication unit. The indication unit includes a slide slot formed in a handle, an indicating member disposed movably on the handle and having a guiding projection movable within the slide slot, and a revolution number scale disposed on the handle and adjacent to the slide slot. The indicating member is connected to and co-movable with the adjusting member. | 04-02-2015 |
| 20150122089 | SCREW DRIVING DEVICE WITH ADJUSTABLE COUNTERSINK DEPTH - A screw driving device with adjustable countersink depth has a resilient depth adjustment sleeve that permits a depth to which a screw is driven by the device to be adjusted by rotation of the resilient depth adjustment sleeve. Rotation of the resilient depth adjustment sleeve is impeded by engagement of a detent in elongated axial stop grooves in an interior wall of the resilient depth adjustment sleeve so that an adjusted position is not lost during normal use. | 05-07-2015 |
| 20160101508 | SHAFT RATCHET RELEASE AND SEALING MECHANISM - A torque wrench having a handle and an output shaft is disclosed. The output shaft may be constrained to turn only unidirectionally due to a ratchet. Rotation of the output shaft may be permanently disabled by an internal mechanism. Torque imposed on the output shaft may be limited by a torque responsive cam clutch. The handle forms or is part of an enclosure enclosing internal components such as the ratchet, the internal disablement mechanism, and the torque responsive cam clutch. A seal between the body and the output shaft prevents ingress and egress of lubricants and contamination between the inside of the body and the output shaft. | 04-14-2016 |

The detent is received in the through hole and partially protrudes into the insertion groove. The abutting assembly is sleeved outside the rod body, and the detent is sandwiched between the abutting assembly and rod body. The first elastic member abuts against the rod body and abutting assembly to bias the abutting assembly toward an abutting position. The connecting rod further includes at least one abutting section protruding radially and an annular groove, and is axially movable relative to the rod body to comoving or idling position. | 04-21-2016 |
