CLASS 35: Hoists.

Patented in the German Empire on October 16, 1881.

This screw winch should preferably be used where pulley blocks, wall, walking, rotating, ceiling and similar cranes or similar lifting devices cannot be attached, or where they obstruct the traffic. It consists of a spindle a, which at its upper end carries a head piece b covered with planks for receiving the objects to be lowered or lifted. In order to protect the spindle and head piece against lateral fluctuations, the same is provided with two strong brackets, each of which carries two rollers guided in strong rails.

The spindle is moved up and down by rotating the bevel gear c running on balls and the wheel C ₁ , which sits on the shaft d , which is driven by the gear reduction f and the chain wheels g gi . This gear transmission is arranged in such a way that loads can be moved up and down at three different speeds. If there is mechanical driving force, the sprocket g _{1 is replaced by} one fixed and two loose pulleys for open and crossed belts, which are driven by the main shaft using a cable disengagement so that either the open or the crossed one Belt comes into effect.

The balls on which the bevel gear c runs are held at a certain distance from one another by a ring y provided with corresponding holes. To protect against rust, the spindle is surrounded by a sufficiently wide tube, which at the same time contains the oil necessary for lubrication.

The gear transmission / on the block i can be attached at any distance from the spindle α and also in any direction, as it is movably connected by the drive chain k to the shaft d , which, as a result of the arrangement of the bevel gear mechanism c C ₁ , is directed in every direction can be. If a spindle with a thread of not too great a pitch is used, it stands by itself at any height without any special device, so that safety and safety devices are superfluous. The shaft opening is closed by a cover provided with correspondingly long feet, FIG. 2. The same is opened when the spindle is moved upwards, in that the head piece b lifts it out through the feet.
