Title: Rotary cultivator dog clutch noise reducer - using spigot inserted to hold free ring against rotation on disengagement
IPC: F16D11/04
Filed: 1976-05-13
Abstract: Drive from the engine is transmitted by a chain to a sprocket wheel (11) mounted freely at the junction of the two wheel shafts. two sliding rings (15) one on each side of the sprocket, carry dogs (13) to engage in slots in the sprocket and are spring (12) loaded towards the sprocket. Between each ring and the shaft is fitted another ring (16) freely mounted on the shaft. The mating faces of the two rings (15, 16) have a sinusoidal form for meshing. Gaps between the sinusoidal teeth on the free ring (16) allow a manually operated spigot (18) to be inserted and stop the ring which rotates when the clutch is engaged. As the ring is stopped, the sinusoidal teeth force the sliding ring outwards along the shaft, disengaging the dogs. On further insertion, the spigot enters recesses (19) in the sliding ring to prevent intermittent re-engagement.

Title: Large dia. bale press - has roller engaged with endless apron to close exit from forming space as formed bale is discharged
IPC: A01F15/07
Filed: 1976-10-19
Abstract: The large dia. bale press has an auxiliary roller (15) which engages the endless bale-forming apron (12). This closes the exit from the bale-forming space (14) as the rear frame (21) is pivoted upwards about its pivot (23) on the front frame (1) to discharge the formed bale. The auxiliary roller is linked to the rear chassis (21) to move to its closing position when the chassis pivots upwards. A locking device (40) holds the roller in its closing position while the rear chassis is pivoted upwards. Downwards pivoting of the rear chassis releases the locking device.
