Abstract: “CONVEYOR SYSTEM WITH DIFFERENT APPLICATIONS AND ISOLATION OF THE CONVEYED PRODUCT IN RELATION TO THE DRIVE SYSTEM”, is a conveyor for grains, seeds, fruit, granulated and ground products and similar products. The conveyor has different applications and isolates the product conveyed from the drive system. There are two or more tubes, and in each set of tubes there is a swivel with a drive system using roller chain, chain, cable, belt, et cetera. In this manner, the drive system is isolated from the product, avoiding mechanical damages, contamination, and also increasing the performance of the system.

Abstract: A conveyor chain and system includes a conveyor chain having of side link assemblies and flight arm assemblies to form an elongated chain. The flight arm assemblies include an opposing flight arm that has an elongated body and an integral base formed with the body. A vertical sprocket opening is formed in the integral base and extends vertically through the integral base to engage a tooth of a drive sprocket to drive the flight arm. The side link assemblies include opposing side straps that include a base and a pair of side strap bosses extending outwardly from the base. The side strap bosses engage a tooth of a drive sprocket to drive the side strap. A driving member includes a pair of sprockets to engage the link and flight arm assemblies from both sides of the chain. An alternative embodiment incorporates a third sprocket located between the other sprockets.

Abstract: A chain driven by two sprockets spaced a short distance apart along their common axial centerline. The chain includes elongated pins that extend beyond the outer surfaces of the chain link plates, on both sides, by a distance about equal to the width of the spaced apart sprockets. The chain is aligned midway between the sprockets, and the sprocket teeth drive on the extended portion of the chain pins. Where a flight is attached to the chain links, the pins are extended still further, to fit into the indentations or holes in the flights. This provides an exposed length of each pin in alignment with the sprocket on each side for driving purposes. The chain has a piece extending between the plates to reduce the likelihood of a pin extending further outside of one side plate or the other. A shoulder on the pin further reduces the likelihood of this happening.

Abstract: A transmission system for transmitting pushing forces along straight and curved paths includes a guide channel (1) and a line of transmission members (10) arranged in the guide channel. The transmission members are acted on by a drive. The transmission members (10) are in contact with each other at end contact faces where the contact faces are formed with mating ring-shaped ridge (11) and a ring-shaped groove, respectively. The ridge (11) and groove (12) are matched to each other such that they are positioned inside each other when the members are arranged coaxially and contacting each other. The cross sections of the ridge (11) and groove (12) are such that ridge and groove are pivotable in relation to each other when engaged. A line of such transmission members arranged in a straight line and pressure loaded forms a buckling-resistant bar which does not exert forces on straight regions (1.2) of an enclosing guide channel (1). In curved guide channel parts (1.

Abstract: An automatic retractor system for retracting a finger element extending from a transport belt, as for example, in a document set compiler and eject apparatus, including a belt transport system having ejector fingers extending therefrom for assisting in the transport of the document set from a compiler tray to an output tray. In particular, the automatic retractor includes a restraint arm coupled between the transport belt and the free end of the eject finger for pulling back on the finger as the belt travels over the circumference of a roll member defining the path of travel of the transport belt.

Abstract: An improved drag link chain is fabricated from a plurality of links joined together in articulated relationship for moving bulk material along a trough or other conveying surface. The links are made having an open end and a closed end. The closed end includes a barrel having a flat side for pushing material. The barrel is disposed within the closed end with its flat side facing inwardly from the closed end toward the open end of the link. The barrel has a rounded back side that seats on a tooth of a sprocket so that a joint of articulation is caused between an inner diameter of a bore of the barrel and an outer diameter of a pin that joins together open and closed ends of tandemly connected links to form an endless drag chain. The barrels of the links, when engaged by teeth of a sprocket are seated thereon with no relative rotation therebetween and thereby avoid excessive wear on the barrels and the teeth of the sprocket.

Abstract: A horizontal plow system method and apparatus has been developed for the homogenous blending and reclaiming of bulk solid particulate matter, such as coal, at a utility plant. The horizontal plow system apparatus comprises one or more displacement assemblies, each further comprising a receiving stationary top plate and a horizontal flight subassembly. Coal is deposited via gravitational forces from an elongated slot bin storage onto the receiving stationary top plate and is then pushed on a bias and ultimately displaced by angular flights during travel of the horizontal flight subassembly along the receiving stationary top plate. Operation of the displacement assembly serves to displace the bulk solid from the sides of the receiving stationary top plate such that portions of coal from along the entire length of the elongated slot bin storage are continuously and simultaneously falling onto a moving transfer belt below, thereby insuring a more even blending of the coal.

Abstract: Drag type feed chains employing links interconnecting one with the other at positions sufficiently above the center lines of the links to increase the strength of the associated abrasion dragging surfaces of the links.

Abstract: The entraining element is constructed of a carrier, a striking member and a support member. The striking member is fixed to the conveyor chain via the carrier and has a resilient striking plate which extends transversely of the gripper shuttle path for returning a shuttle to the picker. The support member is mounted behind the striking plate to define a gap with the striking plate in the unloaded state. Upon deflection of the striking plate during loading, the plate abuts resiliently against the support member.

Abstract: A chain drive includes an endless chain formed of forked links and trained about a drive sprocket and a return sprocket. Each sprocket includes circumferentially arranged teeth and a polygon which radially supports the chain links as they travel about the sprockets. The drive sprocket engages the links only with the leading flanks of the sprocket teeth, while the return sprocket engages the forked links only with the trailing flanks of the sprocket teeth.

Abstract: A cargo transport system is provided for a vessel in which a transfer mechanism separately transfers discrete cargo loads from a loading station on the deck of the vessel to a vertically extending conveyor system. A powered cargo delivery system sequentially forces cargo loads from the loading station onto the transfer mechanism. A sensing device detects the approach of a receptacle of the vertically extending conveyor system and actuates the transfer mechanism to transport one load from the loading station to the approaching receptacle. The sensing device also actuates the cargo delivery system to force the following cargo load onto the transfer mechanism after the elapse of a pre-set interval during which time the transfer mechanism transfers a load to a receptacle and returns to a load acceptance position. The cargo delivery means is preferably formed of sprockets turning an endless chain to which are fastened push bars.

The construction of the links and pivot pins is such that the links and pivot pins can be disconnected without the use of tools. One of the lower links has a pusher dog thereon and is constructed and arranged to permit removal and assembly thereof without the use of tools with respect to the remainder of the chain.
