The present invention relates generally to the field of electrical wire feeding. More specifically, the present invention relates to a fish tape drilling attachment device primarily comprised of a housing, further comprised of at least one bearing, at least one shaft, at least one cam, and at least one cam lever. A fish tape can be fed through the housing such that it is contacted by the cam, wherein the shaft can spin freely within the housing via the bearing such that the hammer action of the drill causes the fish tape to act like a spring to slowly move the fish tape through a piece of conduit. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices, and methods of manufacture.
A fish tape is a thin piece of steel wire in a flat style that is coiled at a predetermined length. To be able to pull a wire through a pipe/conduit, you must first run the fish tape through the pipe. When pushing a fish tape into a conduit, friction is created. To overcome this friction, electricians typically pinch the fish tape with a pair of pliers and rapidly push the tape into the conduit in bursts. This movement makes the tape act like a spring to slowly move the tape through the conduit. However, this method is extremely inefficient, time-consuming, and physically exhausting. In addition, fish tape often gets stuck at the ends of long conduits. Extra manpower is usually needed to pull apart conduits at the end of runs to help feed the fish tape through as well. Hazards may also occur when technicians climb up into rafters to pull apart electrical wiring systems. All these extra steps and roadblocks result in increased costs and decreased productivity for electrical companies.
Therefore, there exists a long-felt need in the art for a device that aids an electrician in running fish tape more efficiently. There also exists a long-felt need in the art for a fish tape drilling attachment device that eliminates the need to use lineman pliers and the need to pull apart conduits. Further, there exists a long-felt need in the art for a fish tape drilling attachment device that can be universally used with any drill.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a fish tape drilling attachment device. The device is primarily comprised of a housing further comprised of at least one bearing, at least one shaft, at least one cam, and at least one cam lever. A fish tape can be fed through the housing such that it is contacted by the cam. The shaft can spin freely within the housing via the bearing such that the hammer action of the drill causes the fish tape to act like a spring to slowly move the fish tape through a piece of conduit.
In this manner, the fish tape drilling attachment device of the present invention accomplishes all of the foregoing objectives and provides a more efficient method of running fish tape. In doing so, the device eliminates the need to use lineman pliers and the need to pull apart conduits. Further, the device can be universally used with any drill making it extremely versatile.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some general concepts in a simplified form as a prelude to the more detailed description that is presented later.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a fish tape drilling attachment device. The device is primarily comprised of a housing, further comprised of at least one bearing, at least one shaft, at least one cam, and at least one cam lever. The housing is preferably generally cylindrical in shape and is comprised of a front wall, a side wall, and a rear wall. The rear wall is comprised of at least one opening that allows at least one shaft to reside within an interior space of the housing. A first end of the shaft is preferably a standard quick-connect shaft that allows the device to be attached to any power drill known in the art. At least one first bearing attaches to or contacts the second end near the rear wall within the interior space which ensures alignment of the shaft within the opening and interior space during use. At least one second bearing attaches to or contacts the second end near the front wall within the interior space that allows load from the shaft to be applied and rotation to continue.
The housing is further comprised of at least one cam located within the housing, wherein the position of the cam within the housing can be adjusted via at least one cam lever. Fish tape can be fed through an opening of the housing that extends from the front wall to the rear wall such that the cam contacts the fish tape within the housing.
After the shaft is attached to a drill via the drill chuck, rotation of the chuck will cause the shaft to spin. The bearings allow the shaft to spin freely within the interior space such that the hammer action of the drill causes the fish tape to act like a spring to slowly move the fish tape through a piece of conduit.
Accordingly, the fish tape drilling attachment device of the present invention is particularly advantageous as it provides a more efficient method of running fish tape. The device eliminates the need to use lineman pliers and the need to pull apart conduits and can be universally used with any drill, making it extremely versatile. In this manner, the fish tape drilling attachment device overcomes the limitations of existing methods of using fish tape known in the art.
