Definitions

• This invention relates to a combination of two trailers to carry grain and grain harvesting headers for combines. More particularly, this invention relates to an improved header trailer that can move combine headers between field locations and can be carried piggyback in over the road transport within the grain bed body of a piggyback transport trailer. This invention relates also to a powered hoist that can be mounted on the combine and used to lift the improved header trailer.
• the type of grain transfer trailer of this invention is novel because of the use of divider doors in combination with the under belly auger. This provides a trailer with partitioned bins that can be used to haul two or more grain loads that must be handled separately.
• sideboards have been common for years. But most types have not been designed for quick removal .
• the sideboard assembly of this invention provides a quick means to fold the sideboards to provide a lower side for easy loading or unloading of the trailer.
• Trailers to haul combine headers have been used for many years.
• the type of trailer used has been one with a structure beneath the header. This invention places the trailer structure over the header so that a hoist can be used to pick-up and rotate the header.
• a novel feature of this invention is to carry the header trailer piggyback inside the grain bed body of the grain transfer trailer.
• a hoist mounted to the front end of the combine is necessary. Hoists have been mounted on combines for many years. The design of prior art hoists, however, is not adequate to safely lift a combine header and header trailer for piggyback transport on the grain transfer trailer.
• the combine hoist of this invention has an extendable foot. This foot protects the combine from being tipped over when lifting a heavy load on the front end hoist.
• This invention provides an improved system for transportation of headers. By carrying the headers within the bed of a grain transfer trailer a more compact loading of field harvesting equipment in over the road transport is facilitated. It is therefore an object of this invention to provide a grain transfer trailer which can carry two combine headers and a header trailer within the grain bed body thereof.
• the header can then be positioned beneath the horizontal overhead structure of the trailer by means of a turntable which rotates the header lifting hoist.

• the grain transfer trailer 30 is pulled by a semi-tractor in over the road operation. At a harvest location the grain transfer trailer would be loaded with grain in the field and carry this cargo to a storage location. The grain transfer trailer 30 would carry two combine headers 60 and the ovehead pick-up trailer 40 to the harvest location.
• FIG. 1 shows the sequence in which the cargo to be carried to the harvest location is loaded into the grain transfer trailer 30.
• First a header 60 is loaded into the lower portion of the grain transfer trailer.
• a second header 60 rides above, carried within the body of the overhead pick-up header trailer 40 which is mounted piggyback on the grain transfer trailer 30.
• the headers 60, and the overhead pick-up header trailer 40 are removed from the grain transfer trailer 30 as shown in FIG. 3.
• the front-end mounted overhead hoist 70 is mounted on the combine 57. First the overhead pick-up header trailer 40, and combine header 60 are removed as one load from their piggyback position and set on the ground. Then a header 60 is removed from the grain transfer trailer 30.
• the front- end mounted overhead hoist 70 is removed from the combine 57 and stowed in an upright position.
• the extendable support members 66 hold the front end mounted overhead hoist 70 in the upright position.
• the header 60 can then be attached to the combine 57 to perform harvesting operations.
• the front-end mounted hoist 70 can be mounted on the combine 57 quickly if needed to provide towing power by use of the horizontal pulling winch 75. This towing power could be used to assist another vehicle that has lost traction in soft ground.
• the overhead pick-up header trailer would be used to move combine headers 60 from field location to field location.
• the overhead pick-up header trailer 40 could lift and rotate the overhead pick-up trailer to be carried under its structure in over the road transport between field locations.
• the grain transfer trailer 30 could receive grain directly from the combine 57 with sideboard assembly 28 folded. With the sideboard assembly 28 in the extended position the grain carrying capacity of the grain transfer trailer 30 could be increased. With the sideboard assembly 28 in the extended position the grain transfer trailer 30 could be loaded by a second grain transfer trailer 30 or similar vehicle.
• the grain transfer trailer 30 is shown in FIG. 1. Its structure includes grain bed body 10, ground engaging wheels 29 and king pin 34 for attachment to semi-tractor.
• the grain transfer trailer 30 is used to haul grain during harvesting operations and transfer grain to other vehicles by using overhead auger 24, fed by vertical auger 23, powered by vertical and overhead auger drive motor 37.
• the grain bed body 10 is divided into three bins by grain bed body divider doors 11.
• the grain transfer trailer 30 could receive grain directly from the combine 57.
• the sideboard assembly 28 could be extended by rotating sideboard scissor jack drive shaft 14 causing sideboard scissor mechanism 15 to open.
• sideboard scissor mechanism 15 opens front sideboard door 16, rear sideboard door 19, and sideboard divider doors 12 extend across grain bed body 10.
• the grain from the grain bed body 10 is unloaded by underbelly auger 22 driven by underbelly auger drive motor 36.
• Flow of grain from the forward part of the trailer is controlled by large bin hopper door 25.
• Flow of graii. from the rear part of the trailer is controlled by medium bin hopper door 26.
• Flow of grain from the center part of the trailer is controlled by small bin hopper door 27.
• the upper bin auger 21 When grain is unloaded from the forward part of- the grain bed body 10 the upper bin auger 21 is turned by upper bin auger drive motor 35. The grain discharged from the upper bin auger 21 flows through large bin hopper door 25.
• the overhead pick-up header trailer 40 is used to move combine headers from one field location to another. Fabric belts extending from the header hoist and turntable 43 are used to lift the lower header cradle 31 or upper header cradle 32 which is mated to the header attachment bracket 33.
• the header attachment bracket 33 is connected to the header 60. On some combine headers the header attachment bracket could remain on the header 60 when it was mounted on the combine 57. On other models it might be necessary to remove the header attachment bracket 33 when using the header 60 to harvest grain.
• the overhead pick-up header trailer 40 is backed with dolly jack stands 46 and 47 and rear-wheeled assembly 42 elevated as shown in Fig. 6.

• the header hoist and turntable 43 can be rotated by the turntable drive motor 44.
• the drive wheels 82 are rotated by drive shafts 84 which receive power from differential gearbox 83.
• Rolling wheels 85 provide horizontal stability for turntable frame 90.
• the track wheels 81 rolling against the turntable track 80 cause the turntable frame 90 to rotate about its center.
• the front-wheeled assembly 47 is lower by the double action hydraulic lift cylinder 68 and the rear-wheeled assembly 42 is lowered by hydraulic lift cylinder 69.
