  • Patent number: 11911878
    Abstract: A ratchet wrench (1) has a flexible clutch ring (500) that forms the mid part of a laminate-like structure comprising a wrench head (200), the clutch ring (500) and a drive element (40). When under load, the compression forces applied to the clutch ring (500) are substantially dissipated around its circumference (508) and inner surface (509), this inward force clamping upon the inherently strong drive outer surface (45). The laminate-like construction enables a reduction in the width or depth of the wrench head without a loss in strength.

  • Patent number: 11883937
    Abstract: The main fixed handle optionally incorporates two swivel out arms, which can form part of a three-legged base. When operated thus, the jaws and moving handle point generally upwards from the formed base, the moving handle can now be operated by one hand leaving the other free to position the workpiece. The moving handle can incorporate a further locking switch that can be utilised in both a switchable locking position or non-locking position upon a sprung toothed strut between the handles, at least one of which further incorporates a curved resilient portion in order to provide useful sprung closure of the parallel moving jaws upon the workpiece in the locking method. A lanyard can be optimally attached to the swivel out arm ends to provide the user with a chest mounted portable vice.

  • Patent number: 11865676
    Abstract: An adjustable wrench (1) with a head portion (200), automatically adjustable within its size range. The fastener (80) to be operated is fitted between the fixed jaw (201) and moving jaw (300), the operators thumb pressure released, automatically propelling the moving jaw 300 towards the fixed jaw (200), the use of four workpiece contacting surfaces (202, 203, 302, 303), two within each opposing jaw (201, 300), engaging the four corresponding actual levered faces (83) to each apply a drive force to a hexagonal fastener head 81. The head portion (200) illustrated in section in order to show the gear teeth (403) on the head end (402) of the handle (400) levering closed the moving jaw (300) via its associated wedge-shaped rack gear (312).

  • Patent number: 11554465
    Abstract: Pliers (1) comprising jaw (201, 301) portions incorporating gripping faces for the clamping of the desired workpiece (90), three pivotal handle (202) portions and a sprung toothed strut (60) positioned between the handles (202). A bow shaped resilient portion (408) or portions, incorporated within the third arm (200, 300, 400) portion, when the pliers are operated this resilient portion imparts a sprung pressure upon the clamped workpiece (90) by the gripping face (203, 303) of the jaws (201, 301). The third arm (200, 300, 400) and bend promoting portion are contiguous with each other. The jaws (201, 301) can further be usefully locked in the required clamping position upon the workpiece (90) by a toothed sprung strut (60) pivotally attached to the first and third arms (200) and conveniently being locked or unlocked according to the locking switch (500, 50) pivotal within the first arm (200, 300, 400).

  • Patent number: 11453103
    Abstract: A locking clutch ratchet wrench (1) is configured such that a clutch ring (500) forms the mid part of aminate like structure. Under torque applying conditions, the compression forces applied to the clutch ring (500) are substantially dissipated around the circumference (507) of the clutch ring. This inwardly directed force clamp against the inherently strong outer surface 405 of the drive element (400). The resultant pseudo laminate structure of the drive element (400), clutch (500) and housing (201, 202) enables the construction of a proportionately stronger ratchet wrench of reduced height or width.

  • Publication number: 20220219293
    Abstract: A ratchet comprises a head portion with a circular central housing having modular inserts in the form of three flat ring like layers, two outer fixed ramped profile layers engaged into housing locking profiles with a sequential actuating layer capable of limited rotation between. Opposing direction pawls are situated within the fixed layer ramped profiles. The actuating layer has engagement and disengagement profiles at either end of its pawl recesses projecting the incumbent pawls against the fixed layer ramped profiles in the chosen direction projecting them inwards locking the pawl teeth within the driven element teeth, whilst simultaneously disengaging the pawls facing the other direction. The actuating layer biasing protrusion resiliently projected in the chosen direction by a robust sprung plunger acting from within a switch bore, in the reverse direction the actuating layer resiliently rotates against said sprung plunger allowing the pawl teeth to resiliently slide over one another.

  • Patent number: 11179829
    Abstract: The ratchet 1 is designed such that the flexible clutch ring 500 forms the mid part of an extremely strong laminate like housing 200 structure, under torque conditions the resultant compression forces applied to the clutch ring 500 are substantially dissipated around its circumference 507 and inner surface 508, this inward force clamping upon the inherently strong drive outer surface 405. The resultant pseudo laminate like construction of the drive 400, clutch 500 and housing 201, 202 enables a proportionately far stronger reduced width ratchet 1.

  • Patent number: 11173581
    Abstract: An adjustable wrench has a wrench head provided with a fixed jaw, a movable jaw carried by the wrench head, a first movable jaw actuator mounted on the wrench head and a second movable jaw actuator mounted on said wrench head. The movable jaw is provided with teeth engagable by the first and second movable jaw actuators and the first movable jaw actuator is movable to an inoperative position to enable actuation of the movable jaw by the second movable jaw actuator.

  • Publication number: 20210122012
    Abstract: The wrench has a thumb switch, when operated, opens against a spring bias the pivotal ring portion around the axis pin attached to the fixed head portion of the wrench head portion, allowing a tube or pipe attached to the fastener to access the confines of the wrench head hexagonal inner profile via the said access channel now provided, the opening of the pivotal ring portion involves approximately 50% of the wrench head portion, the said pivotal ring portion encompassing approximately 50% of the wrench head inner profile. The corner profiles next to the swivel joints are scalloped such that when the pivotal ring is opened the scallops substantially align forming a passageway required for the abutting fastener drive corner to traverse through.
