Aladdin Solid Brass Tilt Frame Hanger

I would attach a wire cable run through a small pulley to the chain and fasten the other cable end to a hook on the wall. Lower the entire assembly to the table to light or extinguish the light. There are also old '60s lamps that have a lowering/raising assembly in the middle of their cords between the ceiling and the lamp which can be modified. (Replace electrical cord with flexible wire). Hope this helps!

As for accessing this overhead light, the one user who tied it to the wall had one idea. One drawback of tying it to something is that you must untie it to get to it and that allows for the possibility of dropping it. I would have one end of the cord secured as a fall stop just in case. But, creative engineers solved this problem long ago. The old fashioned way of dealing with raising and lowering an overhead light is with a counterweight. Run a wire cable through pulleys to and down the wall with a weight the equal to the light. You can then raise and lower the light as desired and it will stay at whatever point you release it. If you want the counterweight out of sight,you can run it up in your attic if that's an option. Of course, you will want to secure the lamp holder whenever you remove the lamp for cleaning or refilling. About that, friction through the pulleys is usually sufficient to prevent the lamp from moving as the oil burns away. The difference in weight is just not that significant unless you have a large font. A counter weight can be made of nearly anything. Cement in a can with a ring bolt to attach the cable to works great. If it is going to be visible, sand or other material could be put in a length of capped PVC tube finished to whatever appearance suits. Old wall clock counterweights might work. This at least suggests some of many possibilities. I hope this helps.
