Patent attributes
A wirelessly controlled apparatus for pulling a free end of wire into the mouth of a conduit and out of the destination end of the conduit. The apparatus includes a wireless spooling controller having an RF transceiver in cooperating communication with a spooling machine having an RF transceiver, for transmitting signaling activating or deactivating the motor-drive of the spooling machine, and for receiving wire-pull completion signaling from the spooling machine. The spooling machine includes a chock pivot-mounted at a mounted end to a frame anchoring the spooling machine near the destination end of the conduit, the chock engageable with a motor-driven gear-wheel engageable with a cogged spool-wheel driven by the motor-drive. Pivotal movement of the chock to the gear-wheel facilitates the fulcrumatic disengagement of the gear-wheel from the spool-wheel cogs, to ready the spooling machine in a starting configuration; activation of the motor-driven gear-wheel essentially causes unchocking of the gear-wheel. The spooling machine also includes an extension spring having one end affixed to the motor-drive proximal to the gear-wheel, and another end affixed to the anchoring frame, spring biasing the unchocked gear-wheel into engagement with the spool-wheel cogs.
