A torque limiter and a retrievable chain knocker tool, each separately configured for use with a drain cleaning apparatus are described. The drain cleaning apparatus includes a drum housing defining an interior region, a cable carrier rotatably mounted within the housing interior region, and a transmission assembly operatively configured for transferring rotary power to an end portion of flexible cable retained in the housing.

Torque limiter for powered drain cleaner

Drain cleaners are described that include rotatable drums which retain drain cleaning cable. Mounted on the rotatable drum is a motor and optional gearbox for imparting rotation to the drain cleaning cable. The drain cleaners can also include a cable clamp mounted on the rotatable drum. The drain cleaners are configured such that the rotatable drum is free of positional preference regardless of orientation of the drain cleaner.

A bipod support for a drain cleaning machine is described. The bipod support includes a base, a plurality of legs, a retaining member, and a latch. The retaining member and latch are configured to engage and secure the drain cleaning machine to the bipod support. The bipod support enables rocking movement of the drain cleaning machine while supporting the weight of the machine. Also described are related methods of use of the bipod support.

Motor dampening provisions are described. Incorporation and use of the motor dampener(s) in a rotary type drain cleaning machine enables elimination of a clutch in the machine. Also described are clutch-free drive systems using the motor dampener(s). Also described are torque countering members that are used in conjunction with the motor dampener(s).

A drain cleaning system is described that includes a drain cleaning device with a flexible drain cleaning cable, and two or more sections of guide hoses that can be attached to one another and/or to the device. Also described are systems that include provisions for advancing or retracting the drain cleaning cable and which can also be coupled to one or more of the guide hoses.

A clear or generally transparent cover or enclosure for plumbing tools is described. The clear cover enables viewing of interior regions of the plumbing tools. In particular versions, the covers are used with drum type drain cleaning devices and enable visual inspection of the drum and/or a flexible drain cleaning cable associated with the device.

Clear drum covers for plumbing tools

Various assemblies for indicating movement and direction of drain cleaning cables used in plumbing tools are described. Generally, the plumbing tools include a cam that is in operable engagement with a guide tube. Upon axial movement of cable relative to the tool, the cam causes reciprocal movement of an indicator. The plumbing tools can additionally include switches and/or electronics in communication with the indicator to thereby provide information or processing of tool operation.

Cable coupling assemblies are described which can be readily engaged and separated from one another. The couplings are particularly useful for use in torque transmitting cables such as those used in drain cleaning applications.

Adapters are described which enable a wide array of tools to be secured and/or mounted in a chain pipe vise. Also described are methods of using adapters with chain pipe vises in order to stably mount tools in the chain pipe vise.

Adapters for chain pipe vises

Various feed control devices for plumbing tools such as drain cleaning machines are disclosed. The feed control devices include a collection of angled rollers that contact a cable or snake of the drain cleaning machine. Another collection of a single or dual angled roller(s) are mounted or otherwise engaged with a handle, and can be selectively positioned and contacted with the cable. By changing the position of the handle, rotation of the cable is translated to axial movement thereby advancing or retracting the cable. Also described are drain cleaning devices utilizing the feed control devices.

Battery

Beveling tools having a variety of features are described. The tools can utilize a combination of handles, a protective external frame, guide rollers that are positionally adjusted by swing arms with timing lobes, or by an alternative guide bar mounting system, a helical knurled drive roller, guide rollers that have a convex or crowned face, skewed guide rollers, a positive clutch assembly for governing force applied to the guide rollers, a hand crank assembly for moving the tool when mounted on a workpiece, position adjustment provisions for varying the position of a milling head, and indicators providing visual feedback to an operator.

Transportable beveling tool

Quick release mechanisms for auger type cleanout tools are described. The mechanisms enable engagement and disengagement of a handle to an auger without the use of separate retainers or fasteners. Also described are auger type tools and related methods of use utilizing the quick release mechanisms.

Quick release mechanisms for plumbing tools

An inspection system and method for use in underground utility construction, especially underground boring operations, is provided. The inspection system generally includes a sensor, a sensor carrier apparatus, and an output device. The sensor is employed to obtain inspection data regarding the condition of a tunnel created in an underground boring operation. The sensor carrier is adapted to incorporate the sensor and connect to means for transporting the sensor through the tunnel. The output device receives an output signal from the sensor corresponding to the inspection data and presents it to an operator for interpretation and/or otherwise documents and/or records the inspection data.
