Patent number: 5749208Abstract: The mowing implement of a mowing apparatus, rotating about a vertical axis, is driven over a transmission comprising a freewheel mechanism and driving pins. A drive shaft is connected with the freewheel mechanism so that there cannot be any mutual rotation therebetween. In a basic orientation parallel to the axis of rotation of the mowing implement, these driving pins produce a driving connection between the freewheel mechanism and the mowing implement for driving the latter. In the event of a stoppage of the drive shaft, the driving pins, together with the freewheel mechanism, carry out a lifting motion, which interrupts the driving connection between the mowing implement and the freewheel mechanism. During their lifting motion, the driving pins activate a braking device in the region of the interior of the transmission housing above the freewheel mechanism. This braking device rapidly brings the mowing implement, which continues to run, to a stop.Type: GrantFiled: September 26, 1996Date of Patent: May 12, 1998Assignee: Maschinenfabrik Kemper GmbHInventors: Richard Wuebbels, Alfons Resing

Patent number: 5600941Abstract: In a two-channel magnetic metal detector for a forage harvester, positive and negative adaptive detection thresholds are varied according to long term changes in the noise component induced in detection coils by moving ferrous parts of the crop feed mechanism. The adaptive detection thresholds are set at levels determined by the positive and negative peak averages of the noise components in the channels while the crop feed mechanism is running at normal speed. Start-up transient noise induced in the detection coil as the crop feed mechanism accelerates may exceed the adaptive thresholds as thus set, thereby triggering false indications that a tramp metal object has been detected in the crop feed path. At start-up of the crop feed mechanism, the detection thresholds are raised to prevent false indications. An increase in a channel noise signal is taken as an indication that the crop feed mechanism is accelerating.Type: GrantFiled: March 31, 1995Date of Patent: February 11, 1997Assignee: New Holland North America, Inc.Inventor: Richard P.

Patent number: 4802326Abstract: An overload coupling for the protection of drive trains on machines, particularly agricultural machines powered by a tractor, protects against overloading in at least one rotational direction. A coupling sleeve is mounted for rotation around a coupling hub of the overload coupling. Relative rotation between the hub and sleeve is about a coupling axis. A plurality of circumferentially spaced recesses are provided in the coupling hub which each contain a rotatably mounted rotor. The rotors are mounted about their own rotor axes which are parallel to but spaced apart from the coupling axis. Each rotor contains a radially movable driver cam which is spring-loaded and has cam surfaces for engaging detent grooves in the sleeve. With the driver cams engaged in the detent grooves, relative rotation between the hub and sleeve is resisted. By shaping the cam surfaces and adjacent abutment surfaces of the driver cams, the direction and force of disengagement can be set between the coupling hub and coupling sleeve.Type: GrantFiled: October 14, 1987Date of Patent: February 7, 1989Assignee: Jean Walterscheid GmbHInventor: Hubert Geisthoff

Patent number: 4400930Abstract: A harvester in the form of a self-propelled combine (11) has a crop header (24) and conveying means (31, 32) feeding crop material to a threshing rotor (34). The speed of rotation of the rotor (34) is adjustable by changing the speed of a variable speed belt drive (50) in the drive train from an engine (16) to the threshing rotor (34). The variable speed belt drive (50) is of a type whose speed ratio cannot be changed unless it is running. A special rotor clutch (71) is interposed between the variable speed belt drive (50) and the threshing rotor (34) to permit the variable speed drive to be disconnected from the threshing rotor. Thus, when the rotor (34) stops rotating because of excess crop material, the rotor clutch (71) may be operated to break the power train between the variable speed belt drive (50) and the threshing rotor (34) and the variable speed belt drive (50) may be run and adjusted to a lower output speed.Type: GrantFiled: May 10, 1982Date of Patent: August 30, 1983Assignee: Allis-Chalmers CorporationInventors: Michael L. Huhman, Larry R. James

Patent number: 4323136Abstract: An agricultural machine has at least one movable tool, such as a cultivating rotor, mower or raking member, spreader disc, or other driven member such as a tractor wheel or freely rotatable roller, which parts are interrupted in movement by a protective mechanism. The mechanism can be a pawl device associated with an overload coupling in the drive train that is actuated by a mechanical or electrical monitor to overload the device. The monitor can be a pivoted cover that partly overlies a rear roller or space adjacent same with projections that intercept the roller or a trip bar with contacts that opens or closes a circuit in a system that interrupts the drive to the moving parts responsive to contact with an external object. In another variation, the circuit can have sensors such as infrared or photoelectric cells to detect the presence or lack of presence of a human operator and these sensors can be placed in a tractor cab.Type: GrantFiled: December 4, 1979Date of Patent: April 6, 1982Assignee: C. van der Lely N.V.Inventors: Cornelis van der Lely, Ary van der Lely

Patent number: RE31464Abstract: Quick or instantaneous stopping of rapidly rotating members places severe stress loads on components. These loads are substantially reduced by providing a quick-stopping apparatus including a damped member having an attached element which is movable into engagement with a rotating member. In response to such engagement, the energy of the rotating member is rapidly decelerated through the damped member thus reducing peak stress loads associated with almost instantaneous deceleration.Type: GrantFiled: September 30, 1982Date of Patent: December 20, 1983Assignee: Sperry CorporationInventors: Wayne B. Martenas, Edward H. Priepke, Robert A. Wagstaff
