Embodiment Construction

[0017] The subject threader is of a configuration similar to known manual threaders commonly found in the electrical construction trade. However, embodiments of the subject threader also utilize a motor and drive assembly configured to transmit rotational power from the motor to the rotatable barrel. In many embodiments, the drive assembly includes a gear box incorporated into the handle or housing, and a ring gear positioned along the outer diameter of the rotatable barrel. In certain embodiments, the handle also includes a battery holder or "shoe" for a commercially available lithium-ion battery, such as an 18-volt lithium-ion battery available from Ridge Tool under the RIDGID name. Alternatively, the device can be configured to accept 12-volt lithium-ion batteries available from various suppliers for reduced power and runtime. Typically, the handle includes a trigger and switch arrangement to regulate the operation of the motor. A variety of electric motors can be used in...

Abstract

A motorized threader having a rotatable barrel for pulling a wire through a conduit or other closed area is described. The threader uses an electric motor and a gear assembly to extend or retract the threader and a thread affixed thereto. The threading device comprises an electric mode and a manual mode. When in the manual mode, an operator may manually rotate the barrel to extend or retract the threader.

Description

technical field [0001] This topic deals with what is commonly referred to as a "fish tape". Electrical contractors use this tool when running wire in conduit. Background technique [0002] Threaders have been known for many years and a variety of such products are available from tool suppliers including Greenlee Tool Company, Klein Tools and Southwire Tools. There are also many lower quality brands on the market. All known products share many similar features and generally rely on manual operation to extend and retract the threader from the cartridge housing. [0003] The main function of a threader is to pull electrical leads through a conduit or hollow space such as inside a wall. The basic principle of operation of such tools relies on manually extending a relatively stiff wire and rotating the housing barrel relative to the handle. The needle threader feeds out in a similar fashion to a tape measure. Relatively stiff threader wires can be extended into proposed path...
