Abstract: Drive and driven shafts are rotatably supported in a wall portion of a press frame and have free end portions extending into a gear case. A first drive gear is nonrotatably secured to the drive shaft and a second driven gear is nonrotatably secured to the driven shaft. A T-shaped member is pivotally connected to the wall and has an intermediate shaft member nonrotatably positioned in a slot for longitudinal movement therein. The intermediate shaft has a free end portion extending into the gear case with intermediate gears rotatably mounted thereon. The T-shaped member is arranged to be suitably adjusted to maintain different sized intermediate gears in meshing relation with different sized drive and driven gears so that the drive shaft imparts a preselected angular velocity to the driven shaft through the gear train. A pair of support arms each have an aperture adjacent one end and an elongated longitudinally extending slot adjacent the other end.

Abstract: A method of multiple powder coating wherein articles to be coated are fed to a conveyor which comprises a pair of Geneva gears secured to both ends of a rotatable shaft. The Geneva gears have a plurality of channels around the periphery thereof for holding the articles. The gears are rotated intermittently at an interval of one channel and an article to be coated is fed to a pair of channels at every Y intermittent rotations, where Y is the number of coatings to be applied. The article is coated once in each cycle of rotation of the Geneva gears and is removed following X times Y intermittent rotations, where X is the number of channels around the periphery of each gear. X is odd when Y is even and X/Y is a decimal when Y is odd.

Abstract: The digit rolls of a counter a connected through transfer pinions in that pins extending axially from one roll towards another one engage a pinion once per revolution and the pinion turns the other roll by one step. The pins of the two rolls overlap axially with a slight radial clearance so that the gap between the rolls is just slightly larger than the length of either pin. The pins have semicircular, triangular, trapezoidal or rectangular cross-section.

Abstract: A cyclically operable clutch in which first and second driven gears are provided with interrupted gear tooth sections normally located opposite a motor driven drive gear. The second gear is operably connected to a cyclically operable driven mechanism and the first gear is spring urged to rotate relative to the second gear. A latch normally maintains the first gear out of mesh with the drive gear. Upon release of the latch, the first gear is spring advanced into mesh with the drive gear and a lost motion connection between the driven gears transmits rotation to the second gear to advance the latter into mesh with the drive gear.

Abstract: Perforated information-bearing media in strip form, for example film in cinematographic devices, is driven either intermittently or continuously. The normally used Geneva stop (Maltese cross), which is connected via an output shaft to the sprocket engaging in the film perforations, can be disengaged from the continuously rotarily driven pin disc by axial displacement of either the Geneva stop of the pin disc effected by clutch means. For rewinding or unwinding the film at continuous high speed simultaneously with said clutch-disengagement between Geneva stop and pin disc, clutch members of a continuously driven, on the output shaft axially displaceable and free running clutch disc, engage in the slots or recesses in the Geneva stop at the position of the Geneva stop which corresponds to the frame standstill.

Abstract: Automatic machinery for performing multiple operations on different parts of workpieces includes an incrementally rotating, workpiece supporting turret provided with three workpiece supports. Upon rotating of the turret, a workpiece loaded on a support located at a first position is indexed about the axis of the turret to a second position at which a first operation is performed thereon, then to a third, idle position. Continued rotation of the turret results in an index of the workpiece to the first position, then again to the second position at which a second operation is performed thereon. After the next index to the third position, the workpiece is unloaded from the support. As the turret is indexed, the workpiece is rotated relative to the turret whereupon the workpiece is oriented differently each time it reaches the second position causing the operations to take place on different parts of the workpiece.

Abstract: A torque converter that uses the reaction of energy storing devices to mechanically convert a given input angular velocity into an output torque. The torque converter is comprised of an input shaft which delivers an oscillatory motion to an inertia device, such as a flywheel, through connecting rods and lever arms. The inertia device transfers the oscillatory motion to the output shaft through differential gears and overrunning clutches. In the preferred embodiment, two inertia devices mounted on parallel axes with each 90.degree. out of phase provide a smooth, continuous output torque.

Abstract: A wrapping machine assembly accelerates articles from a supply conveyor to a wrapping conveyor. Separating bars moved in an orbit over the accelerating portion of the assembly enter into the gap between articles created by acceleration of the leading article or articles. The separating bars and the accelerating portion of the machine are driven intermittently by a drive transmission which is synchronized and driven cyclically with the wrapping conveyor. The intermittent drive which forms the novelty of this invention has a belt loop driven continuously in synchronism with the wrapping conveyor. The belt loop drives an accelerating conveyor and the separating bars, but the driving motion is converted to intermittent motion by a pair of idler rolls which engage the opposite reaches of the belt loop, and swing transversely of the belt reaches to alternately lengthen one reach and shorten the other reach.
