NEW ELEVATOR WORKS WITHOUT CABLES
Elevators travel under their own, self-contained power in a system upon which a New York inventor has just received a patent. Each car is suspended from a hollow drum containing a driving motor. Under control of the operator, the drum revolves and climbs a vertical series of rollers by means of a worm on its exterior, as shown in the diagrams. Reaching the top of its endless shaft, the drum inverts itself and starts down the other side, the elevator car remaining upright meanwhile. Advantages of the new system, the inventor declares, are that extra cars may be used during rush hours and withdrawn when not needed; also, that the system removes present restrictions that limit the height of elevator shafts.
Wouldn’t it be easier to just reverse the direction the drum turns when it needs to go down? You’d be able to reuse the old cable-driven elevator shafts, at least.

It is a clever idea for a propulsion system. It would depend on how much power it uses compared to other systems. I do not get how adding more than one car to the same shaft could ever work - the two cars would need to be able to pass each other.

Oh - I see, never mind
This system would probably take way to much energy as there does not seem to be a counterweight.

Interesting idea.
The elevator shaft doesn’t have to be vertical and
doesn’t have to be in the center of the building.
Are there any two axis elevators, real or proposed?

I’m not sure if these count, but the elevator that goes up the Eiffel tower, the one that goes up the St. Louis Arch, and the elevators at the Luxor in Las Vegas all move horizontally as well as they move up and down.

I know that Otis had designed a vertical/horizontal elevator called the Odyssey during the 90’s. Not sure what happened with it.

A paternoster is a two-shaft elevator. See http://en.wikipedia.org/wiki/Paternoster

There is one of these installed in the New York Hall of Science, in the part of the building that dates from the World’s Fair. When I worked there a few years ago employees would avoid it like the plague as you were more likely to get stuck then to make it your destination.
