The patent for this portable reeling device was filed on December 25, 1962. It isn’t just for a jeep, but a jeep-like vehicle is shown and referenced. I’ve never seen any evidence this was ever manufactured; anyone else?

From the patent, “Now with more particular reference to the drawing, FIGS. 1, 2, 3, and 4 show an embodiment of the invention with a jeep as the means to drive a power driven communication wire reel 16. The communication wire is retrieved and wound onto the communication wire reel 16 by activating outwardly an adjustable speed disk 31 with a clutch lever 20. The power to perform this function is derived from a power take-off 38 from the engine.

Persons familiar with jeeps of the military variety know that such jeeps have a transmission which connects the motor to two shafts which are connected in parallel. One of the shafts drives the ground engaging wheels of the vehicle while the other shaft is connected to a power take-off. This power take-01f may be used to drive a hydraulic system or other attachment. In this case, the power take-off 38 is connected to the shaft 37 and thence to a universal joint 36 and, from there, to the clutch for driving the reel. A pressure spring 35 is held in place and away from a spinning friction power disk 33 by means of a bearing 34 which is fixed to the friction power disk 33. The constant pressure which is exerted on the bearing 34 forces the friction power disk 33 outwardly and against the adjustable speed disk 31. By moving the clutch lever 20 to the left, a pivot 40 in a clutch lever support plate 22 will force lever lugs 39 to the right.”
