Abstract: A vibration damper for inhibiting harmonic vibrations in a brake rotor during resurfacing operations is made by forming an elastic tube or band into a closed loop with tubular iron weights strung thereon before the loop is joined. The elastic tube is first stretched lengthwise to make its lateral dimensions small enough to thread through the tubular weights, and the tube is then relaxed and its ends are interconnected. The elasticity of the thus formed damper holds the tubular iron weights in preselected position on the tube and also allows it to be stretched over the edge of brake rotors which vary considerably in size. The resilient tube of the damper resiliently engages the outer periphery of the rotor to retain the weights in place on the periphery of the rotor as the weights damp the vibrations which occur while the spinning rotor is having its radial braking surfaces machined.

Abstract: A machine for repitting peach halves which have previously been subjected to a pitting operation, but wherein the peach halves are not completely pitted because of split or fragmented pits remaining attached to the fruit. The machine automatically feeds the peach halves, centers them relative to a pitting knife, and re-pits the halves to remove any pit fragments which have escaped the initial pitting operation. Since the initial pitting is done by first cutting whole peaches in half along their entire planes and the resulting peach halves cannot be repitted in the same machine, the present peach repitting machine provides a recovery system for the primary pitting operation in order to increase the overall yield without hand-pitting.

Abstract: A fluid-operated cylinder operates a rack which is in constant mesh with a pinion gear. The pinion gear is mounted on the power input shaft of a fluid-operated jaw clutch, having toothed driving and driven elements, and arranged to engage only when the rack is driven in one direction so that the output shaft of the clutch has intermittent rotary motion in one direction. The rack extends through a stop block and includes an axially adjustable collar which abuts the stop block at one limit of movement of the rack. At the same time, a switch actuator on the rack contacts the actuator of a switch mounted on the stop block to reverse the direction of the rack. In order to adjust the driving stroke of the piston rod in the air cylinder, and hence the driving stroke of the rack, the stop block is provided with a toothed mounting surface and can be selectively positioned along a similarly-toothed mounting plate.

Abstract: The foot-operated speed control shaft for the hydrostatic transmission of a garden tractor is provided with an operating handle which is pivoted on the shaft for fore and aft movement, and is slightly flexed laterally. This flexure energizes a friction block which is secured to the handle and slides across a fixed braking surface to arrest the control shaft in any selected rotative position. The upper part of the operating handle includes a tube enclosing a spring-loaded plunger and rod. The rod has a lower end extending past the edge of a quadrant which is secured to the control shaft. According to the position of the plunger, the rod end can be either seated within a notch in the edge of the quadrant, or can be locked out of contact with the notch. Since the quadrant is attached to the control shaft, the two control systems, i.e.

Abstract: A series of articulated product gripper mechanisms are mounted on a continuously operating pickup conveyor having a reach adjacent the product transfer zone of a continuously operating transport conveyor that has cold plates running through a freezing tunnel. The gripper mechanisms are employed to transfer frozen confections such as ice cream bars, ice cream cones, ice cream cups, and stickless or stick novelties from the transport conveyor cold plates to the pickup conveyor. Each gripper mechanism includes replaceable gripping tongs or fingers appropriate to the particular type of confection being handled, and is operable to pick up the moving confection, invert and dip the confection in a coating bath and in a dry confection applicator, and release the coated confection in predetermined orientation onto the inlet conveyor of an associated wrapping machine.

Abstract: A vertically disposed nozzle continuously extrudes a descending column or bar of semi-frozen confection which passes through a ring gear. A cutoff wire is anchored to the ring gear and to a second, laterally adjacent ring gear. Slip rings adjacent the ring gears electrically energize and heat the cutoff wire. Both gears are driven in the same direction, and the anchor points are located to maintain uniform interspacing and thus keep the cutoff wire linear to transversely slice the moving product bar. The gears and cutoff wire are adjustably mounted to be unitarily tilted from the horizontal so that the product bar is repetitively severed along parallel lines to produce slices each having uniform thickness, with the severance lines perpendicular to the side surfaces of the product bar. A wiper is arranged to clean the cutoff wire after each cutting stroke so that the product will not accumulate and burn onto the cutoff wire.

Abstract: A sheet feeding device includes an elevator table for supporting a stack of sheets and a front sheet vacuum head for lifting and presenting the front edge portion of the top sheet to feed rolls. A rear sheet separator includes a pivoted vacuum shoe having a curved, vacuumized face for lifting the rear edge portion of the top sheet prior to directing a rear air jet forwardly between the top upper sheet and the underlying sheet, and prior to feeding of the sheet. A rearwardly directed air jet at the front of the stack cooperates with the rear jet to provide an air cushion beneath the top sheet. The rear sheet separator shoe is mounted on upper and lower links which are actuated by an air cylinder to roll the vacuum shoe along the sheet as the shoe lifts the top sheet.

Abstract: A live roll conveyor receives randomly supplied upstanding containers, such as cans, and arrests the leading cans with a pattern stop bar having pockets that arrange a transverse row of cans to receive a next assembled row of cans in nesting relation. When a backlog of alternately offset rows of cans extends upstream of an overhead clamp spaced from the pattern bar, the clamp locks two rows of containers to hold back the further upstream containers, and the pattern stop moves downstream so that one assembled charge of nested containers is moved unitarily downstream by the live rolls. A separator or retaining plate with downturned edge flanges is placed on the charge of cans, the pattern stop is further retracted to expose an underlying guide bar and allow the charge to seat against the guide bar, a gate is lowered to allow lateral discharge of the charge of cans, and a sweep arm pushes the charge to a laterally adjacent container basket of a containerized cooker.
