  • Patent number: 4790423
    Abstract: Bottles are conveyed by a pair of side gripping belts, either neck leading or base leading in a direction parallel to an axis extending through the neck and the base of the bottle. In the path of the bottle and upstream therefrom is positioned a split ramp, inclined upward relative to the direction of travel. The split ramps interfere with the forward travel of a base leading bottle and cooperates with the gripping belts to cause the neck of the bottle to raise arcuately so as to orient the bottle to a standing position, on its base. Moving belts are disposed between the split ramp. The split ramp allows passage of part of a bottle conveyed in neck leading position such that the moving belts interfere with the forward travel of the neck leading bottle and cause the neck of the bottle to change its direction of travel to an arcuate, upward direction for orienting the bottle to a standing position, on its base.

  • Patent number: 4768640
    Abstract: The invention specifies a method and a device for supplying assembly parts which adhere to or entangle with each other. Individual assembly parts are extracted from an unsorted quantity of assembly parts in a separating or singling operation. These are aligned in a predetermined position and delivered to a delivery point. A partial quantity of separated or singled assembly parts aligned in a predetermined position is formed during a scooping operation. The assembly parts of this partial quantity are extracted singly and in aligned form.

  • Patent number: 4759437
    Abstract: A handrail for an aircraft belt loader in which a pair of parallel support arms pivotally support a rigid rail member with a variable-length link converted to be non-parallel with the support arms when the handrail is erect or operative. When the handrail is collapsed, the link is shortened and a compression spring inside of the link is further compressed so that maximum erecting force is applied when the handrail is stowed.

  • Patent number: 4757893
    Abstract: An apparatus for driving and positively spacing attachments along a moving timing chain is disclosed, consisting of at least three chains or belts and means for driving the chains or belts at different speeds and/or directions relative to each other. Attachment carrying lugs are positively held between a first and second chain for a determined distance over a path defined by the first chain, an then released by the second chain to subsequently move into positive engagement between the first chain and a third chain. The speeds and directions of the chains determine the spacing of the lugs and associated attachments.

  • Patent number: 4756404
    Abstract: A chain for a trough conveyor includes individual chain links connected with each other by hinge bolts. Removable flight attachment members, which may be flat or curved, connected with each other by at least one cross piece are provided on both sides of the chain links. Two bearing blocks are provided, each with a bore for receiving the hinge bolt. The cross piece rests on the trough by way of a rest surface. At least one support surface disposed in relation to the cross piece in the direction of the chain serves for preventing the tipping of the flight attachment arms when under the action of operating forces. An alternative embodiment includes a dual U-shaped frame about a frame of bearing blocks and cross pieces.

  • Patent number: 4750605
    Abstract: A system for transferring workpieces generally vertically from a station at one height in a workpiece support or transfer device to a station at another height in another transfer device or support. The workpiece is moved vertically by an elevator which travels along a path through the stations from a point below the lower station to a point above the upper station. To smoothly and rapidly move the workpiece the elevator is accelerated and decelerated and dwells at least when picking up and depositing a workpiece. To avoid collisions, interference and the necessity of precisely synchronizing movement of the transfer and elevator, when in its fully raised and lowered positions, the elevator is clear of and does not interfere with the transfer and supports and any workpieces in the stations.

  • Patent number: 4749078
    Abstract: Conveyor idler supports and spacing members are secured to a downwardly facing surface or framework, and adjusted laterally and vertically to facilitate accurate alignment of adjacent idlers in a series. Installation is facilitated, since accuracy in boring securing holes in the downwardly facing surface is less critical than with prior art conveyor support structures, in both the lateral and longitudinal directions. Also spacer assemblies are provided for accurately spacing adjacent idler supports.

  • Patent number: 4746000
    Abstract: A curved escalator includes guide tracks for defining a stairway path which includes a constant slope intermediate section, horizontal landing sections, and transient sections smoothly connecting the intermediate section and the landing sections. Each section of differing slope has a differing radius of curvature which when viewed in plan, is inversely proportional to the slope angle, thereby eliminating the need for drive chains to change the distance between the step axles. Turn-around mechanisms that are compact and simple in structure are also disclosed.

  • Patent number: 4744455
    Abstract: A dispenser and component feeder for integration with automated assembly equipment is adapted for the high speed placement of self-orienting components of varying sizes and includes, a linear vibratory chute for transferring the self-orienting components from the storage hopper to an adjustable single roller feed assembly where the self-orienting components are conveyed to a pick-up position, the single roller feed assembly having a roller to facilitate in conveying the self-orienting components, and alternately reciprocating rod members to segregate a self-orienting component at the pick-up position. A pick-up and placement assembly is operative to pick-up the segregated self-orienting component from the pick-up position and move the same to a position for placement on an associated conveyor on the automated assembly equipment.

  • Patent number: 4744457
    Abstract: A method for collecting commodities in a group, a longitudinal series of commodities being fed set by set into a tapered pusher on which stages having enough size to accommodate square commodities are continuously formed, a pusher advancing a length equal to one commodity so that the commodity group is pushed out in such a condition that the contacting surfaces of the commodities in the row disagree with the contacting surfaces of the commodities in the adjacent rows. A device for collecting commodities uses a tapered pusher on which stages having a longitudinal length shorter than a length of a square commodity and a substantially same lateral length as a width of the square commodity are continuously formed, the pusher being disposed on an operation table provided at a side of a conveyor for conveying commodities to move in a longitudinal direction parallel to the conveyor.

  • Patent number: 4741430
    Abstract: A helical conveyor system is disclosed. A conveyor belt 11 is positively driven by drive cage 21 around a plurality of vertically spaced helical loops. A pair of supplemental positive drives 25 and 26, which are driven at the same speed and synchronized with the drive cage, engage the belt 11 near its entry into and exit from the helical portion of its endless path. Vertical driving bars 45 on the drive cage 21 positively engage the cross rod heads 14 of the belt 11 in its helical path. The driving surfaces of the bars 45 are relieved at 61 and 62 to prevent driving engagement with the rod heads 14 over an inlet section of the first loop and an exit section of the last loop. The driving bars 45 also engage the ends of the rod heads 14 to limit the penetration of the driving bars past the edge of the belt.

  • Patent number: 4738774
    Abstract: An apparatus for loading open top grain hopper rail cars and trucks which eliminates the buildup of a core of small material and grains directly beneath the load out spout. Also, the grain will not build up heat as easily with the core eliminated and a more representative sample, for grading purposes, can be obtained from the hopper car or truck. The spout line buster is a small, stove-shaped chamber which attaches to the end of a grain load out spout and is lowered about six inches into the hopper rail car or truck being loaded. The grain passes through the down spout and enters the spout line buster where the flow of the grain is directed and slowed by a series of baffles or flow guides. In the model designed for loading hopper rail cars, the grain strikes a screen assembly consisting of a cone screen and two diagonal screens.
