suitable devices?

Take the two ropes to a wall mounted wheel (if not already fitted) and
then attach both to a small block and tackle with standing block
fitted to the wall.

Using a luff (one double and one single block) you will gain 3 or 4
times mechanical advantage without spoiling the look of the assembly.

has a 6:1 advantage - which might be a bit too much but you could
always re-rig it.
