  • Patent number: 11646539
    Abstract: A crimping tool with a crimping opening extending at an angle to the axial direction of the tool. The tool can include jaws with multiple crimping openings cooperatively defined thereby at different angles relative to the longitudinal axial direction of the tool. For example, the crimping openings can begin at a respective faces of the jaw and such faces can extend at different angles relative to the longitudinal axial direction of the tool. In this manner, the tool can allow crimping of connectors at a variety of different angles, reduce jaw length and width, and improve the leverage of the crimpers.

  • Publication number: 20230134778
    Abstract: Adjustable pliers includes a first plier half, a second plier half coupled to the first plier half, and a stud disposed in a slot of the second plier half. The first plier half includes a first handle and a first working tip opposite the first handle. The second plier half includes a second handle and second working tip opposite the second handle. The slot extends along a path from a first end of the path to a second end of the path, the path extends in a first direction at the first end of the path and extending in a second direction substantially parallel to the first direction at the second end of the path. A performance parameter is defined, at least in part, by a relationship between dimensions of the slot or of the second working tip.

  • Publication number: 20230083975
    Abstract: Tools, for example, hexagon sockets, dodecagonal sockets, splined sockets, wrenches, etc., that have inner surface geometries adapted to engage a flank of a fastener at a point away from a corner of the fastener. This increases the strength and life of the socket, reduces a risk of the fastener becoming locked or stuck in the socket, and reduces the risk of the fastener being stripped or the socket slipping on the fastener.

  • Patent number: 11548120
    Abstract: Disclosed is a tool, such as pliers, with handle offsets and stop features. In an embodiment, the tool has a minimum of about 0.50 inches of clearance between handles in an area where a user's index finger contacts the handles. This is accomplished by offsetting upper and lower handles of the tool. For example, the lower handle may be offset about 1.10 inches from a pivot point between the handles. Similarly, an end of the upper handle may be offset by about 1.150 inches from the pivot point when jaws of the tool are adjusted to a closed position.

  • Patent number: 11541518
    Abstract: Disclosed is a tool head, such as a socket, having an annular groove that allows gripping of the tool head to remove the tool head from a tool having a lug, such as ratchet, torque or impact wrenches. The groove is spaced from the drive engagement end of the socket for improved gripping performance. The groove dimensions were determined to improve gripping performance as well. For example, the groove can have a depth of 0.020?-0.050?, preferably 0.020?-0.030?. More broadly, the groove can have a depth of 5.0%-15.0%, and preferably 5.0%-10.5%, of the drive end outer diameter. The groove can, either alone or in combination with the above ranges, have a width of 0.25-0.47?, preferably 0.29-0.43?. The groove can, either alone or in combination with the above ranges, begin at a distance of 0.070-0.160?, preferably 0.090-0.140?, and have an end of groove farthest from the end of the socket of 0.32-0.63?, preferably 0.38-0.57?.

  • Publication number: 20220234172
    Abstract: High leverage locking-type pliers incorporating a four bar linkage system adapted to amplify force applied by the user to an object gripped between jaws of the pliers. The pliers include first and second handles, first and second jaws, and a center link rotatably or pivotally coupled to the first and second handles. A first link pivot where the center link rotatably or pivotally couples to the second handle may be a first distance L1 away from a second jaw pivot where the second jaw rotatably or pivotally couples the second handle. A first jaw pivot where the second jaw rotatably or pivotally couples the first handle is a second distance L2 away from the second jaw pivot. In an embodiment, the first distance L1 is about 34% to about 70% of the second distance L2.

  • Patent number: 11254552
    Abstract: A lift arm of a floor jack is composed of a number of components made from metal bar stock. The lift arm is adapted to transfer power and motion from a power unit to a saddle, which is adapted to be placed at a lift point of the vehicle, thereby applying pressure to the lift point and raising the vehicle.

  • Publication number: 20210394341
    Abstract: Sockets, for example, hexagon sockets, dodecagonal sockets, and splined sockets, that have inner surface geometries adapted to engage a flank of a fastener at a point away from a corner of the fastener. In general, the sockets engage the flank of the fastener at a distance of about 30 to 60 percent of half a length of the flank away from the corner of the fastener. This increases the strength and life of the socket, reduces a risk of the fastener becoming locked or stuck in the socket, and reduces the risk of the fastener being stripped or the socket slipping on the fastener.

  • Patent number: 11130215
    Abstract: Methods and systems for increasing the efficiency of a remote wrench. The remote wrench can include a flexible plate within the tool housing or as part of the housing that is more flexible than the rigid housing in conventional remote wrenches that has been shown to limit efficiency. Additionally, a fixed support and a base can be provided that are collectively capable of being coupled to the remote wrench, preferably at the flexible plate, to increase efficiency. The remote wrench operation is therefore improved by reducing inefficiencies and providing a maximum torque output.

  • Patent number: 11111119
    Abstract: A hydraulic power unit for a floor jack that includes an internally-adjustable relief valve that is inaccessible to an operator without removing the power unit from the jack assembly and disassembling the power unit. By placing the relief valve inside of the hydraulic assembly, hidden from operators, the relief valve is less likely to be accidently adjusted when using or servicing the jack.

  • Patent number: 10987745
    Abstract: A method of manufacturing a punch, such as a socket punch, using wire EDM with at least six steps. The method involves forming a blank, holding the blank with an adapter, machining grooves in the blank, manufacturing a side relief of a working portion using wire EDM, milling the working portion to a final size, and forming a cone point on the end of the working portion. The method allows the punch to be manufactured more quickly and from a CAD model, therefore removing the need for over-specialized equipment and improving manufacturing times.

  • Patent number: 10864616
    Abstract: A tool that includes a wrench body a first drive end, and a ratchet gear disposed in an aperture in the first drive end. A first cavity is formed in the first drive end and in communication with the aperture. First and second pawls are disposed in the first cavity, and the first and second pawls each includes teeth adapted to engage the ratchet gear. A second cavity is formed in the first drive end and is in communication with the first cavity. The second cavity receives a reversing disc adapted to selectively engage the first and second pawls to cause engagement and dis-engagement of the first and second pawls with the ratchet gear. By orienting the pawls to allow the second cavity to have a minimum depth, the head of the wrench can be stiffened, thereby increasing fatigue strength and rigidity of the wrench.

  • Publication number: 20200306820
    Abstract: A punch, such as a socket punch, with an angle on a portion of the punch and method of manufacturing a punch with an angle on a portion of the punch using wire EDM. A punch for a cold forming process includes a base portion adapted to be a structural backbone for the punch and a work portion extending from the base portion that performs a punching operation. In addition, grooves and a hex portion are formed in the working portion with an electric discharge machining (“EDM”) machine. Further, a cone point is machined on an end of the hex portion and a land area with an inwardly tapered angle formed between the hex portion and the cone point. The punch can be manufactured more quickly and from a CAD model, therefore removing the need for over-specialized equipment and improving manufacturing times.
