Abstract
Abstract Disclosed are cargo-carrying wagons equipped with a lineally elongate conveyor having a rearward intake-end communicating with a low elevation of the wagon cargo-storage comparment, the conveyor being provided with an elongate external tubular housing including a forward outlet-end for cargo discharge and the conveyor housing being pivotably associated with the forwardly disposed drayage or towing vehicle. For apt employment with an agricultural corn planter and analgous towing vehicles having a plurality of laterally spaced cargo-holding bins, an intermediate-hopper underlies the conveyor outlet-end and a pair of horizontal laterally extending secondary-conveyors communicate with the hopper interior and ultimately supply cargo to the cargo-holding bins.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
In combination with an overland tractor vehicle, a cargocarrying rollable wagon having a cargo-storage compartment and including an elongate forwardly and upwardly extending power actuated conveyor lying along a vertical plane and having a rearward intake-end communicating with the wagon at the bottom front portion of the cargo-storage compartment and a forward discharge-end, said conveyor being provided with an external tubular housing connected to the wagon and also including a forward outlet spout depending from the housing adjacent the conveyor discharge-end, said conveyor tubular housing nearer the outlet thereof than to its rearward wagon connection having means for being removably pivotably attached to the tractor hitch for towing purposes, said means including a revolvable stud depending from the housing and lying along the hitch-axis and providing the pivotal connection to the forward tractor means.
Claim 2
Dependent Claim
134 words
In combination with an overland tractor vehicle, a cargocarrying rollable wagon having a cargo-storage compartment and including an elongate forwardly and upwardly extending power actuated conveyor lying along a vertical plane and having a rearward intake-end communicating with the wagon at the bottom front portion of the cargo-storage compartment and a forward discharge-end, said conveyor being provided with an external tubular housing connected to the wagon and also including a forward outlet spout depending from the housing adjacent the conveyor discharge-end, said conveyor tubular housing nearer the outlet thereof than to its rearward wagon connection having means for being removably pivotably attached to the tractor hitch for towing purposes, said means including a revolvable stud depending from the housing and lying along the hitch-axis and providing the pivotal connection to the forward tractor means.
Claim 3
Dependent Claim
20 words
The combination of claim 1 wherein the elongate forwardly extending conveyor is a helical auger having a cylindrically tubular housing.
Claim 4
Dependent Claim
127 words
The combination of claim 2 wherein the pivotably attached drayage means is a conventional corn planter apparatus equipped with a plurality of laterally spaced cargo-holding bins which might take the form of fertilizer-holding bins; wherein there is an intermediate-hopper communicating with the primary-conveyor discharge-end and located above said cargo-holding bins; wherein there is at least one horizontal laterally lineally extending secondary-conveyor attached to and communicating with the intermediate-hopper to move flowable cargo laterally therefrom, said at least one secondary-conveyor being provided with an underlying shielding therealong; wherein there is a plurality of upright delivery-spouts spaced along and depending from the secondary-conveyor shielding to deliver flowable cargo to underlying cargo-holding bins; and wherein the delivery-spouts overlie the respective cargo-holding bins of the pivotably attached corn planter drayage means.
Claim 5
Dependent Claim
45 words
The combination of claim 1 wherein there is an intermediate-hopper underlying the outlet-spout of the primary-conveyor housing and attached to said housing; and wherein there is at least one horizontal laterally extending secondary-conveyor communicating with the intermediate-hopper interior to move flowable cargo lineally laterally therefrom.
Claim 6
Dependent Claim
56 words
The combination of claim 4 wherein there is a pair of laterally extending and lineally-aligned secondary-conveyors communicating with the intermediate-hopper interior, each said secondary-conveyor being provided with an underlying shielding therealong; and wherein there is a plurality of upright delivery-spouts spaced along and respectively depending from the secondary-conveyor shielding to deliver cargo to underlying cargo-holding bins.
Claim 7
Dependent Claim
34 words
The combination of claim 5 wherein each of said secondary-conveyors is a helical auger powerably actuatably rotatable from the forward drayage means; and wherein each auger type secondary-conveyor is provided with surrounding tubular shielding.
Claim 8
Dependent Claim
76 words
The combination of claim 6 wherein the pivotably attached forward drayage means includes a conventional corn planter apparatus equipped with a plurality of laterally spaced distinct cargo-holding bins Such as might be fertilizer-holding bins; wherein the intermediate-hopper is attached to the collar of the primary-conveyor tubular housing; wherein the secondary-conveyor comprises two co-rotatable helical augers rotated by a single actuation means; and wherein the delivery-spouts overlie the respective cargo-holding bins of the corn planter drayage means.
