Abstract: Apparatus and method for automatically and continuously lubricating a rotary drive of an industrial drive such as a pump, roll, or other driven member is disclosed. The apparatus includes a rotary drive coupling assembly that is connected between an input shaft and an output shaft which drives the driven member. There is an axial bore drilled through the center of an input shaft and a transverse bore which communicates with the axial bore and terminates at an exterior of the input shaft. The shaft coupling assembly preferably comprises a first shaft coupling and a second shaft coupling which are connected by a connecting member. A bridge conduit spans the first shaft coupling and terminates at a manifold which is carried about the connecting member. From the manifold, a plurality of injector valves distribute pressurized lubricant delivered by a timed pressure pump to the shaft couplings. Preferably the shaft couplings comprise universal type joint couplings having a plurality of bearings.

Abstract: A sealing strip and joint for a papermaking machine suction roll is disclosed which includes in combination a stationary suction box and a perforated cylindrical shell which rotates around the stationary suction box disposed centrally within the cylindrical shell. The suction box includes slots constructed near at least two outside edges of the suction box extending across the width of the suction box. A composite seal strip extends throughout the width of each slot which includes a plurality of elongated seal strips jointed together end-to-end in the slots. A plurality of joints are spaced along the length of the composite sealing strip defined by ends of adjacent seal strips joined together. The joints include a first end section of a first strip and a second end section of a second strip mated together in an abutting relation. The first end section and second end section have interfitted radius surfaces which mate against each other against the rotation of said cylindrical shell.
