Abstract: A printing system for transferring ink from an inked ribbon supplied from a ribbon roll having a tubular core with an inner surface onto a substrate. The system includes a rotatable locking cam hub having a reel hub with a first surface engageable with the inner surface of the ribbon roll, and an eccentric hub having a second surface engageable with the inner surface of the ribbon roll. The eccentric hub is rotatable relative to the reel hub to provide a variable diameter between the first surface of the reel hub and the second surface of the eccentric hub. The diameter of the locking cam hub may be reduced by rotating the eccentric hub relative to the reel hub to permit disposal of the ribbon roll tubular core about locking cam hub, and the diameter of the locking cam hub may be increased by rotating the eccentric hub relative to the reel hub to engageably retain the inner surface of the ribbon roll by the first surface of the reel hub and the second surface of the eccentric hub.

Abstract: An imprinting system having a typeface for transferring ink supplied from an inked ribbon roll onto a substrate, and an ink ribbon cassette removably coupleable to a mounting member of the imprinting system to facilitate service and maintenance. An alignment member of the imprinting system is disposeable in a first alignment aperture of the ink ribbon cassette to align the ink ribbon cassette relative to the imprinting system. A lever having an engagement surface is pivotally coupled to the ink ribbon cassette and is engageable with a locking pin coupled to the imprinting system, wherein the engagement surface of the lever is engageable with the locking pin as the lever is pivoted to firmly retain the ink ribbon cassette mounted on the mounting member. A handle having multiple gripping members is coupled to an outer side portion of the ink ribbon cassette to facilitate gripping the cassette and for stably supporting the ink ribbon cassette disassembled from the imprinting system.

Abstract: A new and improved indexing table for supporting a workpiece on a machine tool and the like includes a base with a workpiece supporting table carried on a support shaft journaled for rotation to index the workpiece for machine tool operations. A drive system is provided for rotating the table in one direction about a longitudinal axis of the support shaft and an indexing wheel is provided on the shaft having a plurality of index slots spaced angularly around the periphery for securing the table in selected indexing positions. A shot pin is provided for engaging selected slots in the wheel to lock the table in a fixed position and when the shot pin is retracted, the table is then permitted to rotate toward a next indexing position.

Abstract: A gear finishing machine is provided which utilizes a driven rotary finishing gear and two idler finishing gears. In addition a reciprocating oscillatory mechanism that employs leaf springs as the coupling member, changes rotary into reciprocating motion, which serves to oscillate the workpiece gear across the finishing gears. The machine is capable of either burnishing or honing the workpiece gear according to the ratio of the rotary to sliding velocity of the workpiece gear relative to the finishing gears, duty cycle, and loading pressures. Sensors are utilized which detect undersize and oversize gears, the withdrawing of the driven burnishing gear to the correct location to eject the workpiece gear and the presence of gears in the input and output chute which serve as control signals for the machine.

Abstract: A ring gear burnishing machine is disclosed that has a pair of burnishing stations in which ring gear workpieces are burnished in an overlapping cycle that minimizes burnishing time. Each burnishing station consists of a support table which is coupled to an air cylinder spring and is vertically displaceable so that a burnishing gear is placed on the support table when it is in its lowered position, and burnishing takes place when the support table is in its raised position. Burnishing is accomplished by a pair of burnishing gears at each station. One of the burnishing gears of each pair is driven and the other burnishing gear of the pair is an idler gear. A gear engagement mechanism that includes a pivotable support holder and a pair of rollers which engage the periphery of the ring gear is designed so that the rollers, which do not distort the ring gear, push it into mesh first with one of the rotating burnishing gears, and then with the other burnishing gear of the pair.

Abstract: A molding machine into which nested stacks of preforms or parisons at ambient temperatures are loaded, which denests and applies the preforms individually onto complementary shaped mandrels in the machine. The preforms are made of a thermoplastic material, such as polystyrene, and the mandrels of the molding machine are internally heated to heat each parison as the machine is intermittently rotated. The mandrels are circumferentially mounted about a carriage in the machine and the carriage rotates about a horizontal axis. When viewing the machine at the side at which the carriage rotates in a counterclockwise direction, the preforms are individually applied to the mandrels at the 3 o'clock position by a loading mechanism. From the 3 o'clock position around and to the 6 o'clock position each preform is being heated on its mandrel.

Abstract: A boring bar having a removable indexable cutting insert with a plurality of cutting edges is disclosed. The cutting insert is held in place in the bar by a locking finger on an insert clamp which is locked into place by a ball which is wedged against a release pin that engages the clamp. The ball may be moved so as to allow the pin to move, thereby releasing the force applied by the clamp whenever the insert is to be indexed or whenever a replacement of the insert is required. This is achieved by either manual or hydraulic control of a wedge shaft that engages the ball.
