Abstract: A mower-conditioner includes a header or platform which is equipped with a rotary disc cutter bar having a relatively long length with at least two cutting units being outboard of a central discharge passage where a pair of conditioner rolls are mounted for receiving the cut crop. Aiding in conveying crop to the discharge passage are right- and left-hand sets of three crop converging drums provided at each side of the discharge passage. The outer drums of the two sets are respectively mounted to the top of the right- and left-hand end cutting units of the cutter bar while the other two drums on each side are located behind an inward and rearward extending line that is tangent to the cylindrical path traced by the outer and inner ones of the drums on each side of the discharge passage. In one embodiment, a direct drive transmission is provided, and in a second embodiment a hydraulic motor is provided, for driving the inner two converging drums of each set.

Abstract: A rotary cutterbar includes a gear case containing a series-parallel set of gears including idler gears and pinion gears for driving the cutting discs of the cutter units. The gear case includes top and bottom walls and the idler gears are each received on a hub including an enlarged upper end located in a hole provided in the top wall and a threaded lower end screwed into a hole provided in the bottom wall. The hubs each have a plastic outer shell encasing a metal insert extending axially within the shell, with the shell forming the sole contact between each hub and the gear case whereby vibrations and shock loads respectively due to gear tooth contact and a cutter knife contacting an obstacle are absorbed by the shell to lessen the transmission of noise and the magnitude of the impact force. O-ring grooves are provided in the plastic shell and receive o-rings for preventing leakage from the gear case through the holes in the top and bottom walls.

Abstract: A mower-conditioner includes a header or platform which is equipped with a rotary disc cutter bar having a relatively long length with at least two cutting units being outboard of a central discharge passage where a pair of conditioner rolls are mounted for receiving the cut crop. Aiding in conveying crop to the discharge passage are right- and left-hand sets of three crop converging drums provided at each side of the discharge passage. The outer drums of the two sets are respectively mounted to the top of the right- and left-hand end cutting units of the cutter bar while the other two drums on each side are located behind an inward and rearward extending line that is tangent to the cylindrical path traced by the outer and inner ones of the drums on each side of the discharge passage. In one embodiment, a direct drive transmission is provided, and in a second embodiment a hydraulic motor is provided, for driving the inner two converging drums of each set.

Abstract: The invention relates to an airjet weaving-machine auxiliary nozzle (8) in the form of a hollow needle (11) having a closed tip (12), the auxiliary nozzle having a bulge at its distal end extending towards one side only of the nozzle centerline, such that the bulge extends towards a reed of a weaving machine in which the nozzle is installed relative to the centerline.

Abstract: A loom reed including upper and lower bars which support reed dents and extend along the length of the reed is provided with a connecting device for connecting a brace to the upper bar to restrict longitudinal movement of the reed during loom operation.

Abstract: A rotary disc cutter and a rotary impeller are disclosed as examples of devices which utilize a coupling arrangement forming a detent, for the cutter knives of the disc cutter and the impeller tines of the rotary impeller, which acts, in response to centrifugal force during operation, to retain the knives and tines in radially extended positions. In the rotary disc cutter and one variant of the rotary impeller, respective holes in ends of the knives and tines are shaped to cooperate with a square section of respective fasteners so as to accomplish the detent action, while in a second variant of the rotary impeller, the detent action is due to the cooperation between respective fasteners and complementary shaped tine mount sections.

Abstract: A loom reed including upper and lower bars which support reed dents and extend along the length of the reed is provided with a connecting device for connecting a brace to the upper bar to restrict longitudinal movement of the reed during loom operation. A method of bracing a reed against longitudinal movement is disclosed.

Abstract: An elongated connecting blade or bracing element (14) is used to fix a reed (1) to a batten beam (12). The blade runs substantially in the longitudinal direction (A) of the reed (1) and is connected to the upper profiled bar (4) of the reed (1) and to the batten beam (12) while being spaced away from the reed (1), in order to reduce a displacement of the reed (1) in the longitudinal direction (A).

Abstract: A rotary cutter disc includes shields for the nuts of the knife mounting bolts. Each shield includes a U-shaped well in which a respective one of the nuts is located, the well being oriented so that its open side is directed away from the center of the disc, whereby centrifugal force ejects crop particles and other matter from the well. In one embodiment, the shield is provided with inclined wear surfaces which also serve as crop guide vanes. In a second embodiment, the shield is integral with a crop guide vane. In each embodiment, the underside of the shield is provided with a locating lug which is adjacent the knife mount bolt hole in the bottom wall of the shield. The disc is provided with an elongated knife mounting bolt hole and the shield locating lug is positioned to enter the elongated hole alongside the knife mounting bolt so as to properly orient the shield and keep the shield from rotating when the mounting bolt nut is being screwed on or off.
