Abstract: 1493711 Machine for forming round bales HESSTON CORP 20 Aug 1975 [2 Oct 1974] 34515/75 Heading A1F A machine for forming round bales of hay by rolling a hay mass over ground covered with loose hay carries a mechanism 72 at its rear comprising upper and lower rotatable drums 76, 78 around which are looped sideby-side flexible belts 106 which carry a series of bifurcated lifters 108, Fig. 5, to project from the belt as they pass around the drums and serve to sweep up hay and add it to the mass ahead of the mechanism; which mass is rolled along the ground partly by engagement with the forward, upwardly moving runs of the belts 106. The machine comprises a housing 10 provided with opposite side walls 11, open along its front 12, top 14, and bottom 16, and normally closed at its rear 18 by an end gate 20 which is pivotable about a horizontal axis 22 to an open position, Fig. 8. A tongue 24 at the front of the housing adapts the latter for coupling with a towing vehicle. A pair of ground wheels 26 are rotatably mounted on stub shafts 36 on the ends of respective lift arms 34, the other end of the lift arms being pivotably mounted about a transverse axis 32 on the housing 10; a hydraulic assembly 38 on each side of housing 10 interconnects the corresponding lift arm 34 and sidewall 11 to provide raising and lowering of the housing about the axis 32. A lost motion linkage 44 on each side of housing 10 interconnects the rearmost end of the corresponding lift arm 34 and a crank 52, operation of which effects the swinging of the end gate 20 about the axis 22; the linkage is such that a joint 50 is bent when the housing is fully lowered as shown in Fig. 1. As the housing is raised by the hydraulic assembly 38 the joint 50 is straightened out, after this point a catch 60 holding the endgate closed is released and the crank 52 is operated to open the endgate. As shown in Fig. 3, the interior of the housing 10 contains a pair of arched baleforming elements 120, 128 pivoted about transverse axes 124, 134; as the bale builds up the elements are progressively raised against the action of springs 132, 146 from the position shown in full lines to the position shown in dotted lines, to form an expanding forming chamber for the bale. In addition, the axis 134 of the forward element 118 is swingable against the action of spring 146 to the position shown in dotted lines to expand the chamber fore-and-aft as the bale is developed. When the bale has reached its full size in the chamber, cord is fed through tubes 156 which swing to and fro laterally of the bale; the machine is driven onto clear ground and the cord wraps around the bale. When enough cord has been wrapped it is severed by suitable sickles 162, and the endgate is raised to discharge the bale.
