Abstract
Abstract A single axle, vehicle trailer having a platform, or box, that can be easily tilted for loading or unloading without disconnection of the hitch from the towing automobile. The trailer frame is especially designed for antitorque strength and rigidity, relative to its size and weight, rendering it particularly suitable for transporting special loads such as one or two motorized snow vehicles or the like. Four angle members outline the elongated rectangular wheel-carried frame that has a uniquely applied backbone reinforcing it along the longitudinal median and to which backbone the draft tongue or tow bar is pivotally connected.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
180 words
A tiltable trailer comprising an elongated rectangular frame, a pair of wheels supporting said frame, a tongue pivotally connected to said frame and a latch releasably locking the frame to the tongue against relative pivotal movement, wherein said frame consists of front, side and rear angle members, the front and opposite side angle members each having one arm of the angle extending vertically and the other arm extending horizontally inwards and the rear angle member having one arm of the angle depending vertically and the other arm extending horizontally inwardly, the four angle members having their respective inwardly extending horizontal arms in a common plane and being connected to adjoining angle members at the corners of the frame by a welded joint, a vertically disposed transversely extending reinforcing plate attached to each of said front and rear angle members at the center thereof, and a reinforcing backbone disposed on the longitudinal median of said frame being a pipe of rectangular cross section connected by a welded joint to the confronting sides of said front and rear angle member reinforcing plates.
Claim 2
Dependent Claim
180 words
A tiltable trailer comprising an elongated rectangular frame, a pair of wheels supporting said frame, a tongue pivotally connected to said frame and a latch releasably locking the frame to the tongue against relative pivotal movement, wherein said frame consists of front, side and rear angle members, the front and opposite side angle members each having one arm of the angle extending vertically and the other arm extending horizontally inwards and the rear angle member having one arm of the angle depending vertically and the other arm extending horizontally inwardly, the four angle members having their respective inwardly extending horizontal arms in a common plane and being connected to adjoining angle members at the corners of the frame by a welded joint, a vertically disposed transversely extending reinforcing plate attached to each of said front and rear angle members at the center thereof, and a reinforcing backbone disposed on the longitudinal median of said frame being a pipe of rectangular cross section connected by a welded joint to the confronting sides of said front and rear angle member reinforcing plates.
Claim 3
Dependent Claim
112 words
The tiltable trailer according to claim 1, wherein said tongue has a pair of braces secured to opposite sides thereof forwardly of the front of said frame, pivot plates depending at opposite sides of said frame, said braces diverging to opposite sides of the frame to engage said pivot plates, a vertically disposed hinge plate on each side of said backbone just forward of the center of the frame and depending below said backbone to accommodate the rear end of said tongue therebetween, and pivots connecting said tongue with said hinge plates and the rear ends of said braces with said pivot plates respectively, all of said pivots being in axial alignment.
Claim 4
Dependent Claim
57 words
The tiltable trailer according to claim 1, wherein said tongue is a pipe of rectangular cross section directly underlying said backbone and said reinforcing plate attached to the front angle member has a centrally located rectangular tongue-accommodating notch extending therein from the bottom to maintain said tongue in longitudinal alignment with the median of the trailer frame.
