This April 12, 1954, Power Tower patent filing by Wallace Johnson and Robert Fisher was said to be designed for other vehicles besides the jeep, but given it’s length, it’s hard to imagine it would work on anything that wasn’t flat like the top of the jeep.
Here’s a description: The present invention relates to a power tower for use by workmen employed as painters, electrical fixture repairrnen, aircraft maintenance men, window washers, and a multitude of similar occupations wherein it is necessary toperform a task at some distance above the ground and thus ordinarily require the use of ladders or scaffolding of some type. More particularly, the invention relates to a workmans platform supported by a collapsible tower structure which in turn is mounted on a wheeled vehicle.
