  • Patent number: 12134169
    Abstract: A rotary impact tool includes a housing, an electric motor, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece. An anvil has a bore defining a hexagonal cross-sectional shape and having a nominal width of 7/16 inches. A hammer is rotationally and axially movable relative to the anvil for imparting the consecutive rotational impacts upon the anvil. A spring biases the hammer in an axial direction toward the anvil. A battery pack has a nominal voltage of at least 18 Volts and a nominal capacity of at least 5 Ah. The rotary impact tool has an overall weight including the battery pack that is less than or equal to 7.5 pounds.

  • Patent number: 12128529
    Abstract: The device is a multi-purpose drive socket capable of engaging both a penta-bolt and a hex-bolt. The device is specially adapted for use in the utility industry where multiple tools are typically needed for securing electrical equipment. The device contains a retractable plunger that slides in and out of the head opening. To remove a penta-bolt, the user simply presses the plunger head up against the head of the penta-bolt, causing the plunger to retract back into the socket body. Once fully inserted, the user can loosen or tighten the penta-bolt. To remove a hex-bolt, the user inserts the hex-head into a recessed opening in the plunger head and tightens down the hex-bolt until the hex-head breaks off at the shank. In the event the hex-head remains lodged in the plunger, the device also contains an ejector pin capable of dislodging and removing the hex-head.

  • Patent number: 12055260
    Abstract: A speed control apparatus for an inline pipeline inspection tool includes a body configured to be moved by a compressible product moving through a pipeline and a speed control mechanism supported by the body. The speed control mechanism includes a contact member that is positionable against an inner surface of the pipeline and an actuator configured to act on the contact member to adjust a speed of the body when the speed deviates from a predetermined speed. The speed control apparatus forms a drive system that provides forward propulsion to prevent the tool from slowing or stopping due to a problematic feature in the pipeline. The speed control apparatus also forms a brake system that minimizes overspeed conditions that can occur when built-up pressure initially dislodges the tool from the problematic feature in the pipeline.
