Abstract
Abstract The disclosure relates to trailer or semi-trailer body of the wedge type having a horizontal roof and a rearwardly downwardly sloping floor providing a greater height at the rear opening than at the front. The body is of unique construction having the posts and front wall parallel to each other and at right angles to the underframing and lower rail. The roof and rear door frame are disposed at right angles to each other in horizontal and vertical respectively, the arrangement being such as to readily lend itself to mass production of the body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
110 words
In a wedge type trailer body to be mounted on front and rear wheels, an underframe having a lower rail at each side which slopes downwardly toward the rear when supported on the front and rear wheels, side walls comprising a plurality of spaced posts of substantially equal length extending upwardly from said lower side rails at right angles thereto, and a top rail at each side having a downwardly extending flange of a width to overlap the upper ends of said posts when the upper edge portion of said top side rails are disposed in a substantially horizontal plane and said lower side rails slope downwardly toward the rear.
Claim 2
Dependent Claim
110 words
In a wedge type trailer body to be mounted on front and rear wheels, an underframe having a lower rail at each side which slopes downwardly toward the rear when supported on the front and rear wheels, side walls comprising a plurality of spaced posts of substantially equal length extending upwardly from said lower side rails at right angles thereto, and a top rail at each side having a downwardly extending flange of a width to overlap the upper ends of said posts when the upper edge portion of said top side rails are disposed in a substantially horizontal plane and said lower side rails slope downwardly toward the rear.
Claim 3
Dependent Claim
56 words
A wedge type trailer body as recited claim 1, wherein a rear door frame is secured to the end of the body so as to be disposed in a vertical plane at right angles to the plane of the upper edge portion of said top side rails and at an angle to said lower side rails.
Claim 4
Dependent Claim
33 words
A wedge type trailer or semi-trailer body as recited in claim 1, wherein the bottom edge of said flanges has substantially the same slope as that of the side rails of the underframe.
Claim 5
Dependent Claim
41 words
A wedge type trailer in accordance with claim 1, including a front wall disposed at right angle to said lower side rails and at an angle with respect to the plane of the upper edge portion of said top side rails.

Claim 8
Dependent Claim
111 words
In a wedge type trailer body to be mounted on front and rear wheels, an underframe which slopes downwardly toward the rear when supported on the front and rear wheels, side walls comprising upper and lower side rails, respectively, a plurality of spaced posts of substantially equal length extending fron one of said rails at right angles thereto, the other of said side rails having a vertically extending flange of a width to overlap the ends of said posts when the top edge of said upper side rail is disposed in a substantially horizontal plane and the bottom edge of said lower side rail slopes downwardly generally parallel to said underframe.
Claim 9
Dependent Claim
