Control cable

DETAILED DESCRIPTION OF THE DRAWINGS Now, with more particular reference to the drawings, the present invention is a control cable shown generally at 10, which is readily adaptable to be used to operate a toy car 11, or the like, from a remote control box 12 which contains the steering wheel 13 and the battery 23 or other source of electrical power.
The control box also contains the switch 14 which controls both the forward and reverse directions of movement of the toy, as well as regulating its speed.
The toy car 11 can be steered by the steering wheel 13 over the flat surface 16.
The control cable 10 may take the form of an arch above the flat surface 16.
The arching of the control cable keeps it off the flat surface 16 and does not hamper the movement of the car 11.
The control cable 10 is made up of a suitable length of wire 17.
A three to four foot length has been found suitable for the purpose.
At each end of the control cable, the cable 10 has a connector 15 and another connector 15'.
These connectors are interchangeable and will plug into the control box 12 and the toy car 11.
The control cable is made up of a spring wire 17, which may be of a suitable diameter, for example, twenty to thirty thousandths of an inch in diameter, depending on the strength required.
The spring wire is used to carry electric current, as well as to provide a mechanical control means.
The spring wire 17 is turned or twisted by the steering wheel 13 by a belt 43 running over pulleys 45 and 48.
A second electrical conductor is provided by a small wire 18 which may be approximately eight thousandths of an inch in diameter and which may be wound around the spring wire with an insulation between the wire 17 and wire 18.
To make the control cable 10 according to the invention, a spring wire 17 is dipped in a vinyl or other suitable insulation material in the liquid state.
This vinyl material is permitted to harden and the resulting vinyl coating 19 provides electrical insulation for the spring wire 17.
The first vinyl coating 19 then has the small wire 18 wound around it and electrically insulated from it
