BALER STUFFER MECHANISM

ADVANCING MECHANISM AND SYSTEM UTILIZING SAME FOR RAISING AND LOWERING A WORK PLATFORM

Bryant F Webb, Donald 0 Bigelow assigned to New Holland Inc A baler feed assembly includes a stuffer mechanism having a smooth acting lever or slotted member which moves between a substantially vertical position and a substantially horizontal position. The slotted member pivots about a fixed shaft and includes an upper slot and a lower slot. A crank shaft having a roller member associated therewith, engages the upper slot by means of the roller member to thereby impart motion to the slotted member so that the slotted member can move between the aforesaid positions. A spring is connected to the slotted member at one end and to a fixed support at another end. Preferably, the spring is connected so that its line of action is aligned with the center of the fixed shaft when the slotted member is in the substantially vertical position. By this construction, when the slotted member is moved from the vertical position, the spring insures that the roller member, associated with the crank shaft, is in engagement with only one side of the upper slot. This insures that the roller member is free of engagement with the other side of the upper slot, thereby insuring smooth and jitter-free motion of the stuffer mechanism.

Don Gillis A work platform (10) is guided for up and down movement along support columns (12). Advance/retract cylinders (50, 52) are interconnected between a portion (26) of the platform (10) and a first support (28). Advance/retract cylinders (64,66) are interconnected between the platform (10) and a second support (30). Each support is in the nature of a clamping mechanism. Each includes a pair of clamp members (32,34) and (54,56) which are pivotally connected together. Hydraulic cylinders (46,48) and (60,62) move the members (32, 34) and (54, 56) together and apart. When these members (32,34) and (54, 46) are moved apart, they move grip pads (44,58) into gripping contact with the support column (12). When they are moved together, they move the gripping pads (44, 58) out of contact with the support column (12). In use, one support (28, 30) is clamped to the support column (12) while the other is unclamped. The advance/retract cylinders (50,52) or (64,66) associated with the clamped support (28) or (30) are either advanced or retracted, for the purpose of moving the platform (10) relatively along the support column (12). At the same time, the other set of advance/retract cylinders (50, 52) or (64, 66) are either fully retracted or fully advanced, to a start position.

FLYWHEEL MECHANISMS FOR ANTI-SKID BRAKING SYSTEMS Glyn P R Farr, Warwickshire, United Kingdom assigned to Lucas Industries Public Limited Company In a flywheel mechanism of the axially expanding type a clutch plate which is rotatable with a shaft and from which the mechanism is driven, is provided on pitch circles of greater and smaller diameters with outer and inner clutch faces with which complementary clutch faces on the mechanism are alternately engageable. This defines first and second clutch engagements of higher and lower torque settings which are respectively, when the flywheel operative, mechanism is in an inoperative brake-applying position and when the flywheel mechanism is in an operative brake-applying expanded position.

8702106 QUICK DISCONNECT MECHANISM Jeffrey Dean METCALF assigned to SUNDSTRAND CORPORATION In an actuation system having a pair of motors (10, 12) simultaneously operable for driving a movable member through a torque-summing gear box, there is a need to have a simply constructed minimal cost, light weight quick disconnect mechanism operable to disconnect a motor which has failed fixed so that the other motor can continue to operate. The quick disconnect mechanism utilizes a tapered jaw clutch
