A conveyor, for tree stems, formed of a fixed section and of a section capable of pivoting upwardly about an axis transverse to the direction of travel of the tree stems. The fixed as well as the pivotable sections are provided with gripper rollers adapted to drive the tree stems in the conveyor.

A device for moving a wheeled vehicle along a predetermined path having a track alongside the path with pusher means operating slidably along the track and arranged to push against the wheel of a vehicle in the path to move the vehicle along the path and mechanism to move the pusher means slidably along the track.

A conveyor for forwarding carriers along a support, the carriers being engaged by pusher members attached to an endless driven chain supported on a track adjacent to the carrier support. Each pusher member is pivotally mounted and is associated with a pivoted control member located forwardly of the pusher member and connected thereto by a link, the two members being normally urged to positions in which the pusher member is drivingly engageable with a carrier and the control member is engageable ...

A conveyor includes a driving member and a chain consisting of a plurality of articulated links. Each of the links includes a platform adapted to support a load in cantilever manner.

A reciprocating bar conveyor having a plurality of parallel eccentrically supported bars angularly spaced from each other and grouped into at least two sets. Each set may be angularly spaced from each other set, and each set includes at least six bars which are individually angularly spaced from each other bar of the set. Each set of bars is supported on a pair of eccentric axles, only one of which need be connected to a drive motor.

An article conveyor comprising a first pair of plates mounted for cyclic movement with respect to a second pair of fixed plates so as to move an article stepwise along the second pair of plates. Means are provided, operated by the cyclic movement of the first pair of plates, for stopping the first pair of plates in various positions in their path of movement.

Apparatus for conveying sheet material or the like in suspension comprising clamping means adapted to be opened, closed and rotated in response to movement thereof.

A conveyor is conveying ballbearing balls or the like without mutual contact through an apparatus for surface treatment as degreasing of the balls wtih a solvent. The conveyor comprises several stationary and movable support members, the latter being arranged between the stationary members and each member having surface which is inclining downwardly in the direction of transport. At least one of the movable support members is pivotably mounted so that its surface can alter its inclination to inc...

A conveyor for transporting parcel goods and the like over a track comprises a frame and an endless conveyor belt comprising a transport portion and a return portion, which is supported by the frame and which is driven by a driving device. The conveyor belt is provided with a number of elongated (in transverse direction), substantially rigid supporting elements, which are directly or indirectly interconnected and which can pivot relative to each other at least about an axis parallel to the plane...

A conveyor is provided in which the belt or a plurality of bands (2-36) forming a composite belt extend between free running guide rollers (38, 40). A. Drive shaft (50) runs adjacent the belt or bands and one or more pinch wheels are movable by actuators to cause the belt or bands to be driven from the drive shaft.
