Shock protection apparatus

A shock protection apparatus comprising, in combination, a machine being towed, a towing vehicle coupled to and for towing the machine being towed, and an electrically insulating insert coupled between the vehicle and machine to prevent the transfer of an electrical shock from the vehicle to the machine, wherein said machine includes a towing tongue and said electrically insulating insert is constructed and arranged in said tongue so as to provide a gap between separate metal portions of said tongue, and wherein the separate metal tongue portions are spaced apart and the electrically insulating insert has a length greater than the spacing between the separate metal tongue portions so that respective ends of the electrically insulating insert extend into a center hollow section of respective separate metal tongue portions.

For a vehicle that tows a trailing machine or the like, an electrically insulating insert that is disposed between a frame of the vehicle and trailing machine to prevent electrical shock signals from passing from the vehicle to the trailing machine, wherein the trailing machine includes a towing tongue and said electrically insulating insert is constructed and arranged in said tongue so as to provide a gap between separate metal portions of said tongue, and wherein the electrically insulating insert is comprised of a series of telescopically arranged tubular pieces.
