Abstract
Abstract A dump body vehicle including a frame and a body, the rear end of the body being pivotally supported from upstanding resilient suspension assemblies supported, in turn, from crank axles journaled at the rear end of the frame to rock rearwardly at times, the front end of the body being longitudinally slidable relative to the frame and guidedly supported from the frame which is formed to provide a rearwardly and downwardly inclined section which lowers the front end of the body commensurately as the rear end of the body descends during such rocking of the suspension assemblies, whereby the body assumes a substantially horizontal depressed position for easy loading, together with a latching device to hold the suspension assemblies against such rocking for transit. Another latching device can be withdrawn to permit the front end of the body to rise relative to the frame to a dumping position, and a winch and cable are provided to move the body forwardly to transit position and, when the body is in its transit position, to elevate its front end. An open-ended pulley is provided so that the cable may be readily engaged therewith to facilitate the advantageous application of force to move the body forwardly, or disengaged therefrom to facilitate the advantageous application of force to lift the front end of the body.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
154 words
A dump body vehicle comprising a frame, crank axle means journalled at the rear of said frame to support the same, wheels journalled on said crank axle means, suspension means supported from and moving with said means, a body having its rear end supported from said suspension means for rocking movement about an elevated axis parallel with the journal axis of said axle means, means for supporting the forward end of said body from said frame for forward and rearward movement relative to said frame, retractable latch means for restraining sAid axle means, at times, against rocking movement about the journal of said axle means, a second retractable latch means for restraining the front end of said body, at times, against elevation relative to said frame, and means carried by said frame for applying force to said body tending to move said body forwardly, and to elevate its front end, relative to said frame.
Claim 2
Dependent Claim
154 words
A dump body vehicle comprising a frame, crank axle means journalled at the rear of said frame to support the same, wheels journalled on said crank axle means, suspension means supported from and moving with said means, a body having its rear end supported from said suspension means for rocking movement about an elevated axis parallel with the journal axis of said axle means, means for supporting the forward end of said body from said frame for forward and rearward movement relative to said frame, retractable latch means for restraining sAid axle means, at times, against rocking movement about the journal of said axle means, a second retractable latch means for restraining the front end of said body, at times, against elevation relative to said frame, and means carried by said frame for applying force to said body tending to move said body forwardly, and to elevate its front end, relative to said frame.
Claim 3
Dependent Claim
154 words
A dump body vehicle comprising a frame, crank axle means journalled at the rear of said frame to support the same, wheels journalled on said crank axle means, suspension means supported from and moving with said means, a body having its rear end supported from said suspension means for rocking movement about an elevated axis parallel with the journal axis of said axle means, means for supporting the forward end of said body from said frame for forward and rearward movement relative to said frame, retractable latch means for restraining sAid axle means, at times, against rocking movement about the journal of said axle means, a second retractable latch means for restraining the front end of said body, at times, against elevation relative to said frame, and means carried by said frame for applying force to said body tending to move said body forwardly, and to elevate its front end, relative to said frame.
Claim 4
Dependent Claim
154 words
A dump body vehicle comprising a frame, crank axle means journalled at the rear of said frame to support the same, wheels journalled on said crank axle means, suspension means supported from and moving with said means, a body having its rear end supported from said suspension means for rocking movement about an elevated axis parallel with the journal axis of said axle means, means for supporting the forward end of said body from said frame for forward and rearward movement relative to said frame, retractable latch means for restraining sAid axle means, at times, against rocking movement about the journal of said axle means, a second retractable latch means for restraining the front end of said body, at times, against elevation relative to said frame, and means carried by said frame for applying force to said body tending to move said body forwardly, and to elevate its front end, relative to said frame.
Claim 5
Dependent Claim
26 words
The vehicle of claim 1 including manipulable means mounted on said frame adjacent the front end thereof and operatively connected to retract said first-named latch means.
Claim 6
Dependent Claim
26 words
The vehicle of claim 1 including manipulable means mounted on said body near the front end thereof and operatively connected to retract said second latch means.
Claim 7
Dependent Claim
166 words
A dump body vehicle comprising a pair of joined, parallel, longitudinally-extending beams, a crank axle for each of said beams, each axle having an end portion journalled transversely near the rear end of its associated beam, a second transverse end portion upon which a wheel is journalled, and an intermediate body portion, a platform fixed relative to the body portion of each axle and extending forwardly therefrom to overlie the associated beam, suspension means upstanding from each platform, a body having its rear region disposed between the pivotally supported from said suspension means, latch means carried by each beam and engageable with the associated platform, at times, to retain said platforms, and therefore said axles, against turning movement about the common axis of said journalled axle end portions, and means at the forward end region of said body and cooperating with said beams to enforce controlled downward movement of said front body region as said body moves rearwardly relative to said frame to tilt said axles.
Claim 8
Dependent Claim
166 words
A dump body vehicle comprising a pair of joined, parallel, longitudinally-extending beams, a crank axle for each of said beams, each axle having an end portion journalled transversely near the rear end of its associated beam, a second transverse end portion upon which a wheel is journalled, and an intermediate body portion, a platform fixed relative to the body portion of each axle and extending forwardly therefrom to overlie the associated beam, suspension means upstanding from each platform, a body having its rear region disposed between the pivotally supported from said suspension means, latch means carried by each beam and engageable with the associated platform, at times, to retain said platforms, and therefore said axles, against turning movement about the common axis of said journalled axle end portions, and means at the forward end region of said body and cooperating with said beams to enforce controlled downward movement of said front body region as said body moves rearwardly relative to said frame to tilt said axles.
Claim 9
Dependent Claim
