Abstract: The printed sheet guide mechanism in an offset printing press comprises a stay provided parallel to a delivery roller which is in frictional contact with the eject rollers to rotate therewith, and a pair of guide members each of which has a slanted or curved guide flap. Each of the guide members is secured to the stay so that they are adjustable in their lateral movement, and is also so adapted as to hold at its both edges the printed sheet delivered out passing between the eject rollers and delivery rollers. The guide flap provided in each guide member is designed to bend or curve both edges of the printed sheet to give stiffness thereto.

Abstract: A fluid bearing system for journalling a rotatable shaft in which an annular housing is fixed about the shaft and is provided with an inlet for the supply of fluid under pressure. At least one bearing compression chamber is formed in the housing and/or the shaft and is distributed about the periphery of the shaft. The housing and the shaft form an integrated throttle control means in which a restrictor opening and a discharge opening is formed between the housing and the shaft for the flow through of fluid from the inlet. The openings are simultaneously varied relative to each other in an opposing manner as a function of the size and distribution of the load placed on the shaft.

Abstract: A vehicle has, at at least one end, bumper apparatus that includes a bumper oriented transversely of the vehicle and located at a particular distance from a traveled surface on which the vehicle is supported. In order to maintain the distance between the bumper and the traveled surface generally constant, a support is provided for the bumper. The support is coupled to two mounts that impact different movements to the support upon movement generally perpendicular to the traveled surface by a vehicle body portion located adjacent the bumper. The different movements imparted to the support effect movement of the bumper relative to the adjacent vehicle body portion opposite in direction and approximately equal in amplitude to the movement of the vehicle body portion. In one embodiment, the support includes a lever and the bumper is mounted at one end of the lever. The lever is coupled to its two mounts at its other end and intermediate its ends, respectively.

Abstract: A ball bushing device adapted to be mounted on a shaft, comprising a sleeve element containing a bore defined by an interior wall surface, plural balls within the sleeve, and a raceway structure between the balls and the sleeve element, the raceway structure having curved elastic plate members and having a generally concavo-convex surface facing toward the shaft and the concave surface facing toward the sleeve element.

Abstract: A capsule positioning machine for supplying a plurality of capsules successively in a predetermined posture, which is useable with the capsules each composed of a container and a cap mounted thereon. The machine comprises a transport drum and an inverting drum both supported for rotation in the opposite directions at the same peripheral velocity and formed with a plurality of pockets. Each of the pockets in the transport drum is stepped to provide a large diameter portion of a diameter slightly greater than the outer diameter of the cap of each of the capsules and a reduced diameter portion of a diameter substantially equal to or slightly smaller than the outer diameter of the cap, but slightly greater than the outer diameter of the container. Any of the capsules received in the respective pockets in the transport drum with the container engaged in the reduced diameter portion can be transferred to the inverting drum thereby to invert the posture of the capsule.

Abstract: A copying machine for producing one or more copy sheets from a document original has a carriage for the original which is driven by an endless circulating chain. The carriage is uncoupled from the chain at each end of its reciprocating stroke and the further movement of the chain then actuates other control functions while the carriage is stationary and uncoupled. Only one driving motor is therefore needed in the machine. The copy sheet guide path is defined in relation to the movement of the carriage so that a copy sheet traverses the whole guide path during one reciprocating stroke of the carriage. The copy sheets are held in a cassette-type stack holder which is inserted vertically and which forms an extension of a vertical leg of the copy sheet guide path.

Abstract: Paper inserts, such as statements, payroll checks, and the like, are stacked on the downward sloping bottom of a hopper behind inward extending front stop plates that form a clearance over the hopper bottom. A pair of pinch rollers are constantly driven in front of the stop plates to pass on inserts delivered thereto. At least one front feed roller is disposed substantially below the stop plates and two rear feed rollers are disposed behind the stop plates. The front and rear feed rollers are of resilient material and project upward above the bottom of the hopper. A cylindrical gate is adjustably positioned above the front feed roller so that an intermittent rotation of the feed rollers advances the lowermost insert of the stack under the gate to be engaged by the pairs of constantly driven pinch rollers.

Abstract: A tensioning mechanism for the chain of a scraper elevator device that includes a pair of pivotally interconnected lever arms which support guide rollers. The lever arms are movable by an adjuster link in a scissors fashion for maintaining tension on the chain.
