Tow bar assembly

A tow bar assembly adapted to be attached to the front portion of a trailing vehicle, for towing by a towing vehicle having a draft hitch member, comprising:

• a. a cooperative hitch member adapted to detachably couple with said draft hitch member in operative position,
• b. a pair of elongated draft bars having leading and trailing end portions,
• c. means pivotally connecting each of said leading end portions to said cooperative hitch member to permit pivotal movement of said draft bars in a substantially horizontal plane when said hitch members are coupled in operative position,
• d. an attachment member for each draft bar, each of said attachment members having means for detachable connection to a trailing vehicle,
• e. coupling means connecting the trailing end portion of each draft bar to a corresponding attachment member,
• f. each of said coupling means comprising a pair of laterally spaced ears projecting rearward from each of said trailing end portions,
• g. said coupling means further comprising a tongue projecting forward from said corresponding attachment member between said ears, and a transverse pin connecting said ears and said tongue for relative pivotal movement about the longitudinal axis of said pin,
• h. the spacing between said ears being greater than the dimension of said tongue in the same direction as said ear spacing, to permit translatory shifting movement of said tongue between said ears.
