Patent number: 4048792Abstract: A forage harvester row crop header having fore-and-aft dividers defining elongated passageways therebetween is provided with a rotary member disposed within a pocket defined in a rear portion of one of the outboard dividers to assist in the feeding of crop along the passageway. The rotary member is capstan shaped having its axis of rotation inclined upwardly and rearwardly with respect to the top surface of the respective outboard divider. The lower surface of the rotary member forms a smooth transition with the top surface of the divider and thus, in profile, the divider and the rotary member are represented by a line which gradually slopes, from the forward end of the divider upwardly and rearwardly and therefrom smoothly contours upwardly and rearwardly a short distance and therefrom upwardly and forwardly, thereby providing a substantially uninterrupted surface for the flow of draped over crop along the divider and the rotary member.Type: GrantFiled: August 11, 1976Date of Patent: September 20, 1977Assignee: Sperry Rand CorporationInventors: Joe E. Shriver, Donald O. Norman

Patent number: 4048862Abstract: A linkage is provided to simultaneously control two independent hydraulic drive motors for a vehicle, each having a control arm movable between a high speed position and a low speed position. The linkage comprises a control shaft having a pair of spaced-apart cam elements mounted thereon which engage each of the control arms to pivot them in opposite direction as the shaft is rotated. The linkage is also movable in an axial direction which thereby insures that both control arms reach corresponding high or low speed positions. For instance, if one control arm should reach a respective position prior to the time the other control arm reaches its corresponding position, further rotation of the shaft and cam elements therewith also results in axial movement thereof thus insuring that such other control arm reaches its corresponding position.Type: GrantFiled: October 14, 1975Date of Patent: September 20, 1977Assignee: Sperry Rand CorporationInventors: Joseph C.

Patent number: 4035999Abstract: A roll forming machine picks up crop material and forms, twine wraps and discharges rolls or large round bales thereof as the machine is continuously moving across the field. The machine has front and rear roll forming chambers. Crop material is being continuously delivered either through the front chamber to the rear chamber of the machine wherein formation of a roll is being completed or to the front chamber of the machine wherein formation of a roll is being initiated as the completely formed roll located in the rear chamber is being twine wrapped and then discharged from the machine. Once the rear roll has been wrapped and discharged from the rear chamber and when the roll in the front chamber reaches a predetermined diameter size, the partially formed roll in the front chamber is then transferred to the rear chamber where formation thereof is continued.Type: GrantFiled: February 9, 1976Date of Patent: July 19, 1977Inventors: Jack W.

Patent number: 4026205Abstract: A machine to form compact rolls of hay of substantial size by picking up a swath or windrow of hay and the like from a field, engage it by cooperating upper and lower endless flexible aprons driven in suitable direction to coil the hay into a compact roll while supported upon floor means mounted stationarily in the bottom of the machine to effect baling of all the hay without loss upon the ground. When the roll type bale of hay reaches a predetermined diameter, the upper apron raises to stop driving the same and provide an exit and the lower apron assists in ejecting the bale onto the ground, or the machine can transport it to a desired location for discharge, if desired. The upper apron initially is in contracted position and means are included to provide tension upon the upper conveyor to resist expansion of the same around part of the roll as the diameter thereof increases, said tensioning means also are such as to provide substantially uniform pressure upon the roll as it increases in size.Type: GrantFiled: June 3, 1974Date of Patent: May 31, 1977Assignee: Sperry Rand CorporationInventors: Allison W.

Patent number: 4020913Abstract: In a draft implement having an input power driveline and a tongue adapted to be articulately connected to a tractor, an arm is pivotally mounted on the tongue and supports the driveline rearwardly of a forward telescoping assembly of the driveline which includes forward and rear universal joints. Centering tension springs extending along the tongue and interconnecting the pivotal arm and the tongue maintain the arm in a centered position in which the rear universal joint is positioned the same distance rearwardly of the tractor/implement articulate connection point as that at which the forward universal joint is positioned forwardly of the connection point. The springs will yield to allow the arm to pivot laterally to either side of the tongue to accommodate bottoming out of the telescoping assembly during sharp turns of the tractor relative to the implement. Once the tractor is re-articulated out of the sharp turn relative to the implement, the springs return the arm to its centered position.Type: GrantFiled: September 15, 1975Date of Patent: May 3, 1977Assignee: Sperry Rand CorporationInventor: George E.
