Abstract
Abstract The structure disclosed embraces a pair of vertical angle iron brackets welded to the rear ends of side walls of a truck service body in the plane of the rear end opening of the latter. A rectangular sheet metal tail gate having tapering end flanges welded thereto, the latter being provided with upper and lower pairs of laterally extending bolts, the lower pair of which extend laterally into vertical slots in the lower portions of said brackets and the upper pair of which extend laterally into notches formed in the upper ends of said brackets. The tail gate is normally held in vertical position closing the rear end of the truck body and is adapted to be readily shifted to horizontally rearwardly extending position by lifting said tail gate to remove the upper bolts from said notches and then swinging it downwardly until the wider lower ends of said end flanges abut against lower end portions of said brackets, this rigidly supporting the tail gate horizontally.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
240 words
In a tail gate structure adapted to be applied as a unit exclusively to a transverse vertical plane provided by the rear end faces of the side walls of the bed of a truck service body, the combination of: a pair of vertical right angle sheet metal brackets having primary aligned webs extending inwardly and secured by welding means to said side wall end faces and having parallel secondary webs extending rearwardly from outer edges of said primary webs, said secondary webs having a pair of aligned notches in their upper ends and a pair of aligned slots near their lower ends; a rectangular tail gate formed of sheet metal to fit between said secondary webs and having upwardly tapered parallel sheet metal flanges welded to its opposite ends, the latter flanges being bolt-hole apertured opposite said notches and slots; and two pair of bolts with spacing sleeves, said bolts penetrating said apertures with said sleeves extending through and occupying said notches and slots in said secondary webs, said tail gate being supported vertically by said bolts, the upper bolts being liftable from said notches to permit the tail gate being swung downward into horizontal rearward extension of said truck bed, the tail gate being supported in its lower horizontal position by said lower pair of bolts and by the wide lower ends of said tapered end flanges abutting flush against lower end portions of said vertical primary bracket webs.

Claim 3
Dependent Claim
68 words
A combination as recited in claim 1 wherein said tail gate is rearwardly bent along its upper and lower edges for reinforcement purposes so as to be received between and be welded to corresponding ends of said sheet metal end flanges, the lower edge of said tail gate being bevel-bent to allow said tail gate to freely rotate about said lower bolts between its vertical and horizontal positions.
