Cable Conduit Motors.

An electrical engineer has invented a device for getting the hauling line for cables and wires through the conduit pipes. It consists of three rubber-tired wheels and a special clockwork arrangement that will send the wheels 400 feet at one winding. This new form of motorcar drags string through the pipe and the rest is easy.
