Default Driving a vertical shaft

Belts do it all of the time.

Consider the old time drill press.

The spindle is verticle to the ground. So the pulley
runs in the plane of the floor, but elevated to the top of the
drill press.

The motor is mounted on a plate on the floor or below the head of the
drill press. It is a horizontal (normal mounting) with a cone facing
the user with the axis perpendicular to that of the post or spindle.

In the back are re-direction pulleys that take the loop from the top cone
horz back and over the re-direction pulley - down to the motor cone, around
and back up over a second re-direction pulley on the way back to the top cone.

The belt is a L shape and the belt is round or 4 sided.

Here is a concept:

Dad had one - but these are used on other tools.

How do you drive a vertical shaft with a horizontal motor mount?

I understand mitre gear, spiral gear and a worm drive. Is there another way?
I have been looking through several texts and am not having much luck. Is
there a way to do it with a chain? I cannot see a V-belt doing it. Some sort
of friction drive instead of gears? But how good is the power transmission
in such case?

Thanks,
