Abstract: An electric overhead trolley conveyor is described whereby electric trolleys can drive automatically with reduced velocity in inclining, declining or vertical sections or in selected horizontal sections of the rail without a special control of the electric motor or the drive. For this purpose, chains or racks are provided in sections for reduced speed which mesh with sprocket wheels or gears of the electric trolleys. In the other areas of the rail the electric trolleys are driven by a drive wheel. The circumferential velocity of the drive wheel is greater than the circumferential velocity of the sprocket wheel or gear. In the slow movement sections the circumferential velocity difference is compensated by the drive wheel which has an outer ring, that may rotate relative to an inner hub which is fixedly connected with the drive shaft.

Abstract: A power and free conveyor system wherein a plurality of conveyor units or trolleys in the form of part suspension frames and the like may be moved by a continuously moving chain but the relationship of the chain to each conveyor is such that no latching or unlatching of the units is necessary to stop a particular unit at a station or when a stack-up of conveyor units occurs. Resumption of motion occurs automatically when intentional stopping or stack-up is relieved. The drive chain engages a plurality of freely rotating sprockets arranged on the trolley in a manner in which the chain forms a loop diverging from the general alignment of the chain. The acceleration and drive of the trolleys is thus controlled by a variable tension arrangement on one of the drive sprockets of the chain.

Abstract: A lower chord electric trolley conveyor comprising a rail with an upper flange which is directly connected to a support structure. The electric trolley receives its current from a bus bar attached to the rail. The drive wheels of the trolley engage the upper side of the lower flange of the rail. Upper flanges extend from a vertical web of the rail toward both sides while a lower flange extends only toward one side. The electric trollery wraps around the lower part of the rail. It comprises counter pressure rolls in front of and behind the drive wheel. The counter pressure rolls engage the surface of the upper flange which faces the lower flange. Several support rolls engage both sides of the vertical web of the rail. The bus bar is connected to the side of the vertical web of the rail facing away from the drive wheel.

Abstract: A detachable chair or gondola lift is disclosed wherein an alternator is driven by a rope bull-wheel. The alternator supplies a synchronous motor for driving friction wheels or other mechanisms for driving the cars in an end station of the chair or gondola lift. The electrical connection between the alternator and the synchronous motor ensures synchronous rotation of the motor. The alternator can be connected to the bull-wheel by a multiplier gear, the bull-wheel being either a tension bull-wheel or a driving bull-wheel. In the case of a tension bull-wheel, the alternator is mounted on the bull-wheel support carriage to avoid a flexible mechanical transmission. The alternator can be coupled to the high speed shaft of a driving bull-wheel reducer gear, for example, by a trapizoidal belt transmission. At low speed, the excitation of the alternator is increased to preserve the synchronism of the movements.

Abstract: A vertically adjustable emergency support for the bodies of, for example, rail vehicles. Due to wear of the wheel tires, the bogie frame and the car body supported on it tend to descend. In the case of emergency supports in the region of the center pivot, where access is difficult, it is proposed, in order to compensate for this drop, to connect the striker plate which faces an emergency spring at a distance "w" to a box underneath which as vertically guided via guide elements on sliding-contact liners of a cut-out in the bogie frame. If the distance "w" increases due to wear of the wheel tires, an adjustment has to be made by raising the box via a plate connected to the center pivot. Plates of a thickness which compensates for the wear are inserted between the box and abutments which are connected to the bogie frame. After securing the plates via bolts, the car body is lowered again, whereupon the distance "w" is restored.

Abstract: A trolley pole is supported on a vertical shaft so as to be rotatable from side to side while in its elevated, operating position. The shaft is supported on a support structure which is tiltably mounted on a base plate on a vehicle. The base plate can be tilted by extending the arm of a linear actuator. When the base plate is tilted, the pole is lowered and centered and a gravity operated latch structure comes into effect to maintain the pole centered whenever it is not in its operating position. A control circuit coupled to the actuator extends and retracts the actuator arm to pivot the support structure between an upright and a stowed position.
