  • Patent number: 6619486
    Abstract: A self-pivoted catcher for the up-stacking of die-cut thermoformed components comprises a low mass loop of material having opposed ends thereofjournaled in a guide pin which is affixed in a narrow web of a catcher plate between apertures therein. The catcher is adapted to move upwardly with movement of the die-cut component as the individual component is separated from a previously die-cut larger sheet of components by the pusher as the pusher is advanced through the catcher plate. The loop is also adapted to engage the underside of a lip of the die-cut component thereby retaining the die-cut component on an upper side edge of the catcher.

  • Patent number: 6599078
    Abstract: An assembly for positioning and removably supporting cargo on the exterior of a vehicle, wherein the cargo is preferably mounted on a mobile carrier assembly such as a hand truck. A hoist assembly includes a winch and lifting cable and is concurrently supported, along with the mobile carrier, on a base which is removably secured to a hitch structure mounted on the vehicle. A support assembly is secured to the base and is structured to independently but concurrently support both the hoist assembly and the mobile carrier, with or without the cargo thereon. Upon removal of the mobile carrier from the vehicle, the cargo supported thereon can be transported over the ground or other support surface to an intended location for use without requiring repeated loading and unloading of the cargo from the mobile carrier.

  • Patent number: 6598725
    Abstract: A coin acceptor produces an output or operates a switch or vending mechanism when a coin acceptor slide reaches a certain point of advance relative to a housing. The slide receives coins or tokens tendered by a customer (“coins”) and carries the coins into a discriminator responsive to size, shape or the like. The discriminator can have feeler levers, a limited passage size or similar features that permit the slide to advance if all the correct coins are present, or obstruct movement of the slide if coins are missing or are the wrong type. The discriminator is breakable with sufficient force, which could break away the feeler levers or other test structures the obstruct movement unless the correct coins are in place, which would permit the slide to be operated repeatedly without the correct coins.

  • Patent number: 6582180
    Abstract: An object-sorting system has a conveyor having a horizontally extending stretch, a plurality of pushers fixed on and spaced along the conveyor and extending upward from the stretch thereof, and an upright chute adapted to hold a stack of objects and having a downwardly open outlet spaced above an upstream end of the conveyor stretch. An elongated support surface extends horizontally above the stretch and has an upstream end below the outlet port. A drive advances the stretch and thereby displaces the pushers downstream past the outlet so that the pushers engage at least a lowermost object of the stack in the chute and move the engaged object(s) downstream along the support surface. The support surface can pivot about an axis at the support-surface downstream end and thereby change a vertical spacing between the support surface upstream end and the outlet port.

  • Patent number: 6565427
    Abstract: In a coin pay-out device to which the present invention is applied, the rotary arm of the second change slide is extended to a space between adjacent first change slides and the rear end side of the rotary arm is used as a stopper for disabling the rotation of the rotary arm. Consequently, it is possible to dispose the solenoids of the second change slide and the solenoids of the first change slides side by side. As a result, the disposition space of each solenoid can be reduced both in the transverse direction, as well as in the front-rear direction, thereby the whole size of the coin pay-out device can be reduced. Furthermore, because the second change slide is the rotary arm that turns around the fixed supporting member having a movable supporting member at its tip, which is to be fit in the guide groove of the pay-out link, the second change slide is simplified in structure.

  • Patent number: 6558109
    Abstract: Wafers are separated individually from a stack by directing multiple jets of fluid between an outermost wafer in the stack and an adjacent wafer. The jets have sufficient pressure and are sufficiently spaced apart around the wafer stack to cause the outermost wafer to separate longitudinally from the adjacent wafer without lateral movement there between. In the illustrated embodiment, a chuck is attached to a planar surface of the outermost wafer. The attached wafer and wafer stack, once separated by the jet of fluid, are moved relatively apart, such as by movement of the chuck. The wafers in the stack are thereby separated without contact between a wafer edge and a solid object (such as a container wall or hand), minimizing the risk of wafer breakage.

  • Patent number: 6550600
    Abstract: A plurality of gates with control arms and cam arms that pivot to open and close a plurality of coin stalls, so that a coin will enter the first open stall, engage the cam arm to pivot the control arm to close that stall, and come to rest on one of a plurality of support arms. A coin select mechanism includes an actuator operatively connected to a coin select member with pins that engage slots with openings in the arms. The actuator is selectively operated to slide the coin select member to align one of the pins with the opening of one of the arms, to permit that arm to pivot to release the coin in that stall. A coin release mechanism includes an actuator operatively connected to a release member with pins that engage the release the arms so that only the desired coin stall is emptied.

  • Patent number: 6533529
    Abstract: An adjustable coupling connector apparatus for accommodating a range of mating excavator couplers. The connector apparatus includes two parallel bars upon which an excavator coupler clamps. One of the bars is fixed in position to risers extending from a connector base. Each end of the other bar is attached to a point off center of a circular plate so that as the plate is rotated, the bar moves laterally relative to the bar axis. The plates are rotatably positioned in holes in the risers, and captivating side plates are welded to the risers for covering a portion of each plate, securing the plates from movement parallel to its axis but allowing the plate to rotate. Holes in the circular plates and side plates are provided, and a bolt is placed through each of the side plates and circular plates for securing each circular plate in a fixed position.
