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.

Abstract: A method is disclosed for converting a mechanically-actuated drive unit to an air-actuated drive unit (18) in an industrial power transmission system of the type having a short-shaft motorized input drive employing an input shaft (16) releasably connected to an output shaft (20) by the drive unit. A spider (14, 42) having a hub (50) is affixed to the input shaft. The drive unit has an input member (86) connected to a radial flange (68) of the spider and an output member (92) connected to the output shaft. The drive unit includes an actuator member (88) for releasing and connecting the input and output members. In the method, the mechanically-actuated drive unit is replaced with the air-actuated drive unit. A diameter of the spider hub is reduced and a rotary air seal adaptor (12) is affixed directly onto the reduced diameter spider hub.

Abstract: A method and apparatus are illustrated for converting a brake on a rotating turret arm 12 of a paper unwinding stand 10 from a disc brake unit to a drum brake unit which includes providing an adapter bracket 30 by means of which the turret arm 12 accommodates drum brake structure in place of the disc brake unit. The adapter bracket means 30 includes an attachment flange 32 which attaches directly to a mounting plate 22 of a removed disc brake unit 20. A support flange 34 is carried by the attachment flange which pivotably supports brake shoe means 36, 38 which engage a brake drum 46 adapted for connection to an end 16a of the paper roll shaft 16. The drum is hollow and includes a rotary union 60 through which a cooling fluid is circulated.
