A conveyor trolley for use in a conveyor system of the type referred to as "power and free systems" is provided with a driving pawl and a backup pawl at its forward end, and means for lowering both pawls as the trolley is moved through a transfer station from a powered main line to a powdered, secondary storage or processing line. The trolley is also provided with a normally inactive dog on its rearward end that is raised only at the transfer station into the path of the pushers of the main line...

A plurality of cylinders are connected to rollers that are in contact with one of two endless conveying belts of a conveying apparatus to control the forces exerted on an article being moved by said apparatus.

A conveying system for a hydrostatic cooker having carrier bars mounted on a processing conveyor of predetermined pitch, and having removable adapters for adapting carriers to controllably handle a wide range of container sizes, including easily deformable containers such as aluminum or plastic containers supported on their ends. The adapters are removably mounted on the carrier bars and have a curved camming surface adapted to cam containers that are supported on their ends into positions where...

An extruder conveying screw comprising a core having two helical flights thereon, the first of which extends between opposite ends of the screw to define a helical channel and the second of which extends generally across the channel over a portion intermediate the length of the screw, and a casing around said screw characterized in that said second flight is terminated at its upstream end in spaced relationship to the wall of the first flight and further in that the second flight is provided wit...

In order to be able to move pellets (10) in different sections of a conveying path at different speeds on chain conveyors (14, 16), without having to use step-by-step transmissions, it is proposed to place the pellets on at least two chain conveyors (14, 16), which travel at different speeds. By controlling the frictional resistance between the contact members (22 to 28) of the pellets (10) and the endless conveyors (14 and 16), it is possible to determine by which of the chain conveyors the pel...

A conveying system including a complex track the sections of which are connected by junctions. Means are provided to prevent the vehicles reaching simultaneously the junction from impinging against each other and to this end feelers are provided on such vehicles so that in the case of a simultaneous arrival, the vehicles are constrained to follow each its normal track assumed to lie parallel with that followed by the other vehicle. Means are furthermore provided for controlling without any compu...

In a system for transporting articles, such as packaging containers, between work stations by means of an endless conveyor having spaced supports thereon and holders for the articles mounted either directly on the conveyor or on the supports attached to the conveyor, the improvement of utilizing permanent magnets for securing the holders in a readily releasable manner. A method is provided which requires that the magnetic field be sufficient to resist gravity separation but insufficient to preve...

In an adjustment zone (B), the spacings between objects, which are conveyed by independently movable holding elements (2) along a rail track (1) are e.g. for a processing operation adjusted to a predefined value larger than the minimum spacing. To achieve this, a continuously circulating and compressible, adjusting chain (5) running in a circulating track is provided, which adjusting chain (5) is elongatable in a controlled manner. The circulating track extends at least in the adjustment zone (B...

A conveying system comprised of a rail and at least one transport hanger which can travel back and forth along the rail on rollers, the rollers having horizontal axes of rotation, the rail having horizontal conveyer support projections which are located at the bottom of the rail and along which the rollers are positioned for travel back and forth along the rail carrying the transport hanger with them, trolley wires which are insulated from one another being located on the rail to the side of the...

A conveying apparatus, particular for use in conveying large products such as engines around a production line, comprises a pallet which is driven with respect to a pair of guide rails. Power supply rails are provided on guide rails and power is drawn from these as the pallet moves to continuously power the pallet without requiring any on board power supply. Coding means are provided at particular spaced locations with respect to the rails and means are provided on the underside of the pallet to...
