Various drop head coupling assemblies are described. The coupling assemblies enable a drop head tool typically used in drain cleaning operations to be releasably engaged with a drain cleaning cable. The coupling assemblies enable the drop head tool to undergo a wide range of motion relative to the drain cleaning cable, particularly during rotation of the cable and drop head.

A powered fish tape having a rotatable drum is described for pulling electrical wires through conduit or other enclosed regions. The fish tape utilizes an electric motor and a gear assembly for extending or retracting the fish tape and wires attached thereto. The fish tape includes a powered mode and a manual mode. When placed in the manual mode, an operator may manually rotate the drum to extend or retract the fish tape.

Battery powered fish tape

Drain cleaning tools are described. The tools typically include a hollow drum for housing a drain cleaning cable, an elongated cable guide, a locking nut engageable with the cable guide for selectively engaging the cable, and a rotatable handle on the cable guide. A particular configuration is used at an open end of the cable guide to facilitate engagement, i.e., selective locking and unlocking, of the cable. One or more flexible members are provided in the cable guide for rotatably retaining the handle about the cable guide.

A locking system is described that is intuitive to use and provides a high degree of security. The locking system is a multipoint locking system and includes a plurality of components that provide engagement between components. Also described are cabinets and enclosures using the locking system.

Tool chest locking mechanism

A C-type tubing cutter is described that accommodates and cuts a range of tubing or workpiece sizes. The cutter includes a radially positionable roller carriage that can be selectively positioned in one of several predetermined positions corresponding to different tubing sizes. The cutter also includes a trigger that can be engaged with the roller carriage to lock the carriage in a desired position. Certain versions of the cutters also utilize arcuate slots or tracks along which a cutter wheel is positionable.

C-type tubing cutter

A hand-held hydraulic assembly includes a work tool having a hydraulic cylinder or main body, a ram piston disposed in the hydraulic main body and a spring or other biasing member mounted on the ram piston. An interchangeable work head is selectively engaged to the ram piston of the work tool. The ram piston is axially displaceable in the main body for actuating the work head. A quick release coupling mounted to the work tool releasably connects the interchangeable work head to the work tool.

Work tools having interchangeable work heads

A tool for selective attachment to pipe or other elongated objects. The tool includes a handgrip for gripping the tool by hand, which is attached to a base. The tool includes a flexible fastener or strap for wrapping around the pipe, and a tensioner for exerting tension on the fastener to clamp the pipe between the fastener and the base.

Gripping tools

Hand tool

Various systems, tools, and methods are described for rendering regions of coated pipe suitable for receiving press fittings. The systems, tools, and methods may also be applicable for transforming regions of pipe, coated or uncoated, and which are otherwise unsuitable for sealingly engaging press fittings, so that reliable and leak-proof seals can be made between the pipe and press fittings.

Preparation tools for pipe ends and related methods

A tool for crimping at least two members together and confirming that the crimp is acceptable. The tool includes a pair of opposed clamping jaws. Each of the clamping jaws has a crimping surface that contacts at least one of the members when crimping the members together. The tool also includes a pair of opposed arms that move the crimping surfaces of the opposed clamping jaws toward one another to define a crimping position and away from one another to define a release position. The tool also includes a gauge that defines a first size determining member that allows receipt of the members crimped together and a second size determining member that rejects receipt of the members crimped together.

A press frame for attaching connectors to workpieces such as cables and pipes is described. The press frame is adapted to be releasably attached to a hand-held, battery powered press tool. The press frame includes selectively interchangeable components that enable a wide range of different styles, sizes, and configurations of electrical connectors to be attached to cables.

Tool for powered pressing of cable connectors

A jaw assembly for use with a crimping tool is described, wherein the assembly includes a jaw arm and a side plate where the side plate is configured to fail in a manner noticeable to a user of the jaw assembly prior to the anticipated failure of the jaw arm. The side plate includes a stress riser, such as a milled slot formed in one face of the sideplate, to ensure such failure.

Controlled cycle-life jaw assembly

Pressing tool body

A jaw arm for a compression tool has a jaw recess at one end and a jaw insert is supported in the recess for pivotal displacement relative thereto about an insert axis. A compression tool comprises a pair of parallel spaced apart side plates, and a pair of the jaw arms pivotally mounted between the plates. The pivotal inserts are self-aligning with respect to a pipe and coupling to be crimped together and provide for use of the compression tool in areas with limited accessibility.

Jaw arm for compression tools

A crimping assembly is disclosed. The assembly includes cam profiles on the ends of the arms. The cam profiles are engaged by the crimping tool and control the input force versus displacement of the tool. The cam profile includes a first portion defined by a radius, a second portion adjacent the first portion and defined by a non-linear equation, and a third portion adjacent the second portion and defined by a linear equation. The assembly further includes a passive mode of failure in the side plates. The arms of the assembly have a hardness greater than the side plates and have a maximum section height at their point of rotation for increasing their strength. The assembly further includes a leaf spring disposed between the arms and held therebetween by pins disposed in holes defined in the sides of the arms. A crimp ring having an increased diameter is disclosed for reducing the crimping force required to crimp 3-inch fittings.
